5 Changes between 0.9.7a and 0.9.8 [xx XXX xxxx]
7 *) Add full support for -rpath/-R, both in shared libraries and
8 applications, at least on the platforms where it's known how
12 *) In crypto/ec/ec_mult.c, implement fast point multiplication with
13 precomputation, based on wNAF splitting: EC_GROUP_precompute_mult()
14 will now compute a table of multiples of the generator that
15 makes subsequent invocations of EC_POINTs_mul() or EC_POINT_mul()
16 faster (notably in the case of a single point multiplication,
18 [Nils Larsch, Bodo Moeller]
20 *) IPv6 support for certificate extensions. The various extensions
21 which use the IP:a.b.c.d can now take IPv6 addresses using the
22 formats of RFC1884 2.2 . IPv6 addresses are now also displayed
26 *) Added an ENGINE that implements RSA by performing private key
27 exponentiations with the GMP library. The conversions to and from
28 GMP's mpz_t format aren't optimised nor are any montgomery forms
29 cached, and on x86 it appears OpenSSL's own performance has caught up.
30 However there are likely to be other architectures where GMP could
31 provide a boost. This ENGINE is not built in by default, but it can be
32 specified at Configure time and should be accompanied by the necessary
34 ./config -DOPENSSL_USE_GMP -lgmp
37 *) "openssl engine" will not display ENGINE/DSO load failure errors when
38 testing availability of engines with "-t" - the old behaviour is
39 produced by increasing the feature's verbosity with "-tt".
42 *) ECDSA routines: under certain error conditions uninitialized BN objects
43 could be freed. Solution: make sure initialization is performed early
44 enough. (Reported and fix supplied by Nils Larsch <nla@trustcenter.de>
48 *) Key-generation can now be implemented in RSA_METHOD, DSA_METHOD
49 and DH_METHOD (eg. by ENGINE implementations) to override the normal
50 software implementations. For DSA and DH, parameter generation can
51 also be overriden by providing the appropriate method callbacks.
54 *) Change the "progress" mechanism used in key-generation and
55 primality testing to functions that take a new BN_GENCB pointer in
56 place of callback/argument pairs. The new API functions have "_ex"
57 postfixes and the older functions are reimplemented as wrappers for
58 the new ones. The OPENSSL_NO_DEPRECATED symbol can be used to hide
59 declarations of the old functions to help (graceful) attempts to
60 migrate to the new functions. Also, the new key-generation API
61 functions operate on a caller-supplied key-structure and return
62 success/failure rather than returning a key or NULL - this is to
63 help make "keygen" another member function of RSA_METHOD etc.
65 Example for using the new callback interface:
67 int (*my_callback)(int a, int b, BN_GENCB *cb) = ...;
71 BN_GENCB_set(&my_cb, my_callback, my_arg);
73 return BN_is_prime_ex(some_bignum, BN_prime_checks, NULL, &cb);
74 /* For the meaning of a, b in calls to my_callback(), see the
75 * documentation of the function that calls the callback.
76 * cb will point to my_cb; my_arg can be retrieved as cb->arg.
77 * my_callback should return 1 if it wants BN_is_prime_ex()
78 * to continue, or 0 to stop.
83 *) Change the ZLIB compression method to be stateful, and make it
84 available to TLS with the number defined in
85 draft-ietf-tls-compression-04.txt.
88 *) Add the ASN.1 structures and functions for CertificatePair, which
89 is defined as follows (according to X.509_4thEditionDraftV6.pdf):
91 CertificatePair ::= SEQUENCE {
92 forward [0] Certificate OPTIONAL,
93 reverse [1] Certificate OPTIONAL,
94 -- at least one of the pair shall be present -- }
96 Also implement the PEM functions to read and write certificate
97 pairs, and defined the PEM tag as "CERTIFICATE PAIR".
99 This needed to be defined, mostly for the sake of the LDAP
100 attribute crossCertificatePair, but may prove useful elsewhere as
104 *) Make it possible to inhibit symlinking of shared libraries in
105 Makefile.shared, for Cygwin's sake.
108 *) Extend the BIGNUM API by creating new macros that behave like
111 void BN_set_sign(BIGNUM *a, int neg);
112 int BN_get_sign(const BIGNUM *a);
114 and avoid the need to access 'a->neg' directly in applications.
115 [Nils Larsch <nla@trustcenter.de>]
117 *) Implement fast modular reduction for pseudo-Mersenne primes
118 used in NIST curves (crypto/bn/bn_nist.c, crypto/ec/ecp_nist.c).
119 EC_GROUP_new_curve_GFp() will now automatically use this
121 [Nils Larsch <nla@trustcenter.de>]
123 *) Add new lock type (CRYPTO_LOCK_BN).
126 *) Change the ENGINE framework to automatically load engines
127 dynamically from specific directories unless they could be
128 found to already be built in or loaded. Move all the
129 current engines except for the cryptodev one to a new
131 The engines in engines/ are built as shared libraries if
132 the "shared" options was given to ./Configure or ./config.
133 Otherwise, they are inserted in libcrypto.a.
134 /usr/local/ssl/engines is the default directory for dynamic
135 engines, but that can be overriden at configure time through
136 the usual use of --prefix and/or --openssldir, and at run
137 time with the environment variable OPENSSL_ENGINES.
138 [Geoff Thorpe and Richard Levitte]
140 *) Add Makefile.shared, a helper makefile to build shared
141 libraries. Addapt Makefile.org.
144 *) Add version info to Win32 DLLs.
145 [Peter 'Luna' Runestig" <peter@runestig.com>]
147 *) Add new 'medium level' PKCS#12 API. Certificates and keys
148 can be added using this API to created arbitrary PKCS#12
149 files while avoiding the low level API.
151 New options to PKCS12_create(), key or cert can be NULL and
152 will then be omitted from the output file. The encryption
153 algorithm NIDs can be set to -1 for no encryption, the mac
154 iteration count can be set to 0 to omit the mac.
156 Enhance pkcs12 utility by making the -nokeys and -nocerts
157 options work when creating a PKCS#12 file. New option -nomac
158 to omit the mac, NONE can be set for an encryption algorithm.
159 New code is modified to use the enhanced PKCS12_create()
160 instead of the low level API.
163 *) Extend ASN1 encoder to support indefinite length constructed
164 encoding. This can output sequences tags and octet strings in
165 this form. Modify pk7_asn1.c to support indefinite length
166 encoding. This is experimental and needs additional code to
167 be useful, such as an ASN1 bio and some enhanced streaming
170 Extend template encode functionality so that tagging is passed
171 down to the template encoder.
174 *) Let 'openssl req' fail if an argument to '-newkey' is not
175 recognized instead of using RSA as a default.
178 *) Add support for ECC-based ciphersuites from draft-ietf-tls-ecc-01.txt.
179 As these are not official, they are not included in "ALL";
180 the "ECCdraft" ciphersuite group alias can be used to select them.
181 [Vipul Gupta and Sumit Gupta (Sun Microsystems Laboratories)]
183 *) Add ECDH engine support.
184 [Nils Gura and Douglas Stebila (Sun Microsystems Laboratories)]
186 *) Add ECDH in new directory crypto/ecdh/.
187 TODO: more general interface (return x coordinate, not its hash)
188 TODO: bug: pad x with leading zeros if necessary
189 [Douglas Stebila (Sun Microsystems Laboratories)]
191 *) Let BN_rand_range() abort with an error after 100 iterations
192 without success (which indicates a broken PRNG).
195 *) Change BN_mod_sqrt() so that it verifies that the input value
196 is really the square of the return value. (Previously,
197 BN_mod_sqrt would show GIGO behaviour.)
200 *) Add named elliptic curves over binary fields from X9.62, SECG,
201 and WAP/WTLS; add OIDs that were still missing.
203 [Sheueling Chang Shantz and Douglas Stebila
204 (Sun Microsystems Laboratories)]
206 *) Extend the EC library for elliptic curves over binary fields
207 (new files ec2_smpl.c, ec2_smpt.c, ec2_mult.c in crypto/ec/).
210 EC_GF2m_simple_method
214 EC_GROUP_new_curve_GF2m
215 EC_GROUP_set_curve_GF2m
216 EC_GROUP_get_curve_GF2m
217 EC_POINT_set_affine_coordinates_GF2m
218 EC_POINT_get_affine_coordinates_GF2m
219 EC_POINT_set_compressed_coordinates_GF2m
221 Point compression for binary fields is disabled by default for
222 patent reasons (compile with OPENSSL_EC_BIN_PT_COMP defined to
225 As binary polynomials are represented as BIGNUMs, various members
226 of the EC_GROUP and EC_POINT data structures can be shared
227 between the implementations for prime fields and binary fields;
228 the above ..._GF2m functions (except for EX_GROUP_new_curve_GF2m)
229 are essentially identical to their ..._GFp counterparts.
230 (For simplicity, the '..._GFp' prefix has been dropped from
231 various internal method names.)
233 An internal 'field_div' method (similar to 'field_mul' and
234 'field_sqr') has been added; this is used only for binary fields.
236 [Sheueling Chang Shantz and Douglas Stebila
237 (Sun Microsystems Laboratories)]
239 *) Optionally dispatch EC_POINT_mul(), EC_POINT_precompute_mult()
240 through methods ('mul', 'precompute_mult').
242 The generic implementations (now internally called 'ec_wNAF_mul'
243 and 'ec_wNAF_precomputed_mult') remain the default if these
244 methods are undefined.
246 [Sheueling Chang Shantz and Douglas Stebila
247 (Sun Microsystems Laboratories)]
249 *) New function EC_GROUP_get_degree, which is defined through
250 EC_METHOD. For curves over prime fields, this returns the bit
251 length of the modulus.
253 [Sheueling Chang Shantz and Douglas Stebila
254 (Sun Microsystems Laboratories)]
256 *) New functions EC_GROUP_dup, EC_POINT_dup.
257 (These simply call ..._new and ..._copy).
259 [Sheueling Chang Shantz and Douglas Stebila
260 (Sun Microsystems Laboratories)]
262 *) Add binary polynomial arithmetic software in crypto/bn/bn_gf2m.c.
263 Polynomials are represented as BIGNUMs (where the sign bit is not
264 used) in the following functions [macros]:
267 BN_GF2m_sub [= BN_GF2m_add]
268 BN_GF2m_mod [wrapper for BN_GF2m_mod_arr]
269 BN_GF2m_mod_mul [wrapper for BN_GF2m_mod_mul_arr]
270 BN_GF2m_mod_sqr [wrapper for BN_GF2m_mod_sqr_arr]
272 BN_GF2m_mod_exp [wrapper for BN_GF2m_mod_exp_arr]
273 BN_GF2m_mod_sqrt [wrapper for BN_GF2m_mod_sqrt_arr]
274 BN_GF2m_mod_solve_quad [wrapper for BN_GF2m_mod_solve_quad_arr]
275 BN_GF2m_cmp [= BN_ucmp]
277 (Note that only the 'mod' functions are actually for fields GF(2^m).
278 BN_GF2m_add() is misnomer, but this is for the sake of consistency.)
280 For some functions, an the irreducible polynomial defining a
281 field can be given as an 'unsigned int[]' with strictly
282 decreasing elements giving the indices of those bits that are set;
283 i.e., p[] represents the polynomial
284 f(t) = t^p[0] + t^p[1] + ... + t^p[k]
286 p[0] > p[1] > ... > p[k] = 0.
287 This applies to the following functions:
292 BN_GF2m_mod_inv_arr [wrapper for BN_GF2m_mod_inv]
293 BN_GF2m_mod_div_arr [wrapper for BN_GF2m_mod_div]
296 BN_GF2m_mod_solve_quad_arr
300 Conversion can be performed by the following functions:
305 bntest.c has additional tests for binary polynomial arithmetic.
307 Two implementations for BN_GF2m_mod_div() are available.
308 The default algorithm simply uses BN_GF2m_mod_inv() and
309 BN_GF2m_mod_mul(). The alternative algorithm is compiled in only
310 if OPENSSL_SUN_GF2M_DIV is defined (patent pending; read the
311 copyright notice in crypto/bn/bn_gf2m.c before enabling it).
313 [Sheueling Chang Shantz and Douglas Stebila
314 (Sun Microsystems Laboratories)]
316 *) Add new error code 'ERR_R_DISABLED' that can be used when some
317 functionality is disabled at compile-time.
318 [Douglas Stebila <douglas.stebila@sun.com>]
320 *) Change default behaviour of 'openssl asn1parse' so that more
321 information is visible when viewing, e.g., a certificate:
323 Modify asn1_parse2 (crypto/asn1/asn1_par.c) so that in non-'dump'
324 mode the content of non-printable OCTET STRINGs is output in a
325 style similar to INTEGERs, but with '[HEX DUMP]' prepended to
326 avoid the appearance of a printable string.
327 [Nils Larsch <nla@trustcenter.de>]
329 *) Add 'asn1_flag' and 'asn1_form' member to EC_GROUP with access
331 EC_GROUP_set_asn1_flag()
332 EC_GROUP_get_asn1_flag()
333 EC_GROUP_set_point_conversion_form()
334 EC_GROUP_get_point_conversion_form()
335 These control ASN1 encoding details:
336 - Curves (i.e., groups) are encoded explicitly unless asn1_flag
337 has been set to OPENSSL_EC_NAMED_CURVE.
338 - Points are encoded in uncompressed form by default; options for
339 asn1_for are as for point2oct, namely
340 POINT_CONVERSION_COMPRESSED
341 POINT_CONVERSION_UNCOMPRESSED
342 POINT_CONVERSION_HYBRID
344 Also add 'seed' and 'seed_len' members to EC_GROUP with access
348 EC_GROUP_get_seed_len()
349 This is used only for ASN1 purposes (so far).
350 [Nils Larsch <nla@trustcenter.de>]
352 *) Add 'field_type' member to EC_METHOD, which holds the NID
353 of the appropriate field type OID. The new function
354 EC_METHOD_get_field_type() returns this value.
355 [Nils Larsch <nla@trustcenter.de>]
362 providing useful interfaces to EC_POINT_point2oct() and
363 EC_POINT_oct2point().
364 [Nils Larsch <nla@trustcenter.de>]
366 *) Change internals of the EC library so that the functions
367 EC_GROUP_set_generator()
368 EC_GROUP_get_generator()
370 EC_GROUP_get_cofactor()
371 are implemented directly in crypto/ec/ec_lib.c and not dispatched
372 to methods, which would lead to unnecessary code duplication when
373 adding different types of curves.
374 [Nils Larsch <nla@trustcenter.de> with input by Bodo Moeller]
376 *) Implement compute_wNAF (crypto/ec/ec_mult.c) without BIGNUM
377 arithmetic, and such that modified wNAFs are generated
378 (which avoid length expansion in many cases).
381 *) Add a function EC_GROUP_check_discriminant() (defined via
382 EC_METHOD) that verifies that the curve discriminant is non-zero.
384 Add a function EC_GROUP_check() that makes some sanity tests
385 on a EC_GROUP, its generator and order. This includes
386 EC_GROUP_check_discriminant().
387 [Nils Larsch <nla@trustcenter.de>]
389 *) Add ECDSA in new directory crypto/ecdsa/.
391 Add applications 'openssl ecparam' and 'openssl ecdsa'
392 (these are based on 'openssl dsaparam' and 'openssl dsa').
394 ECDSA support is also included in various other files across the
395 library. Most notably,
396 - 'openssl req' now has a '-newkey ecdsa:file' option;
397 - EVP_PKCS82PKEY (crypto/evp/evp_pkey.c) now can handle ECDSA;
398 - X509_PUBKEY_get (crypto/asn1/x_pubkey.c) and
399 d2i_PublicKey (crypto/asn1/d2i_pu.c) have been modified to make
400 them suitable for ECDSA where domain parameters must be
401 extracted before the specific public key;
402 - ECDSA engine support has been added.
403 [Nils Larsch <nla@trustcenter.de>]
405 *) Include some named elliptic curves, and add OIDs from X9.62,
406 SECG, and WAP/WTLS. Each curve can be obtained from the new
408 EC_GROUP_new_by_nid(),
409 and the list of available named curves can be obtained with
410 EC_get_builtin_curves().
411 Also add a 'curve_name' member to EC_GROUP objects, which can be
415 [Nils Larsch <nla@trustcenter.de, Bodo Moeller]
417 *) Remove a few calls to bn_wexpand() in BN_sqr() (the one in there
418 was actually never needed) and in BN_mul(). The removal in BN_mul()
419 required a small change in bn_mul_part_recursive() and the addition
420 of the functions bn_cmp_part_words(), bn_sub_part_words() and
421 bn_add_part_words(), which do the same thing as bn_cmp_words(),
422 bn_sub_words() and bn_add_words() except they take arrays with
426 Changes between 0.9.7 and 0.9.7a [XX xxx 2003]
428 *) Add support for FreeBSD on IA64.
429 [dirk.meyer@dinoex.sub.org via Richard Levitte, resolves #454]
431 *) Adjust DES_cbc_cksum() so it returns the same value as the MIT
432 Kerberos function mit_des_cbc_cksum(). Before this change,
433 the value returned by DES_cbc_cksum() was like the one from
434 mit_des_cbc_cksum(), except the bytes were swapped.
435 [Kevin Greaney <Kevin.Greaney@hp.com> and Richard Levitte]
437 *) Allow an application to disable the automatic SSL chain building.
438 Before this a rather primitive chain build was always performed in
439 ssl3_output_cert_chain(): an application had no way to send the
440 correct chain if the automatic operation produced an incorrect result.
442 Now the chain builder is disabled if either:
444 1. Extra certificates are added via SSL_CTX_add_extra_chain_cert().
446 2. The mode flag SSL_MODE_NO_AUTO_CHAIN is set.
448 The reasoning behind this is that an application would not want the
449 auto chain building to take place if extra chain certificates are
450 present and it might also want a means of sending no additional
451 certificates (for example the chain has two certificates and the
455 *) Add the possibility to build without the ENGINE framework.
456 [Steven Reddie <smr@essemer.com.au> via Richard Levitte]
458 *) Under Win32 gmtime() can return NULL: check return value in
459 OPENSSL_gmtime(). Add error code for case where gmtime() fails.
462 *) DSA routines: under certain error conditions uninitialized BN objects
463 could be freed. Solution: make sure initialization is performed early
464 enough. (Reported and fix supplied by Ivan D Nestlerode <nestler@MIT.EDU>,
465 Nils Larsch <nla@trustcenter.de> via PR#459)
468 *) Another fix for SSLv2 session ID handling: the session ID was incorrectly
469 checked on reconnect on the client side, therefore session resumption
470 could still fail with a "ssl session id is different" error. This
471 behaviour is masked when SSL_OP_ALL is used due to
472 SSL_OP_MICROSOFT_SESS_ID_BUG being set.
473 Behaviour observed by Crispin Flowerday <crispin@flowerday.cx> as
477 *) IA-32 assembler support enhancements: unified ELF targets, support
478 for SCO/Caldera platforms, fix for Cygwin shared build.
481 *) Add support for FreeBSD on sparc64. As a consequence, support for
482 FreeBSD on non-x86 processors is separate from x86 processors on
483 the config script, much like the NetBSD support.
484 [Richard Levitte & Kris Kennaway <kris@obsecurity.org>]
486 Changes between 0.9.6h and 0.9.7 [31 Dec 2002]
488 *) Fix session ID handling in SSLv2 client code: the SERVER FINISHED
489 code (06) was taken as the first octet of the session ID and the last
490 octet was ignored consequently. As a result SSLv2 client side session
491 caching could not have worked due to the session ID mismatch between
493 Behaviour observed by Crispin Flowerday <crispin@flowerday.cx> as
497 *) Change the declaration of needed Kerberos libraries to use EX_LIBS
498 instead of the special (and badly supported) LIBKRB5. LIBKRB5 is
502 *) The hw_ncipher.c engine requires dynamic locks. Unfortunately, it
503 seems that in spite of existing for more than a year, many application
504 author have done nothing to provide the necessary callbacks, which
505 means that this particular engine will not work properly anywhere.
506 This is a very unfortunate situation which forces us, in the name
507 of usability, to give the hw_ncipher.c a static lock, which is part
509 NOTE: This is for the 0.9.7 series ONLY. This hack will never
510 appear in 0.9.8 or later. We EXPECT application authors to have
511 dealt properly with this when 0.9.8 is released (unless we actually
512 make such changes in the libcrypto locking code that changes will
513 have to be made anyway).
516 *) In asn1_d2i_read_bio() repeatedly call BIO_read() until all content
517 octets have been read, EOF or an error occurs. Without this change
518 some truncated ASN1 structures will not produce an error.
521 *) Disable Heimdal support, since it hasn't been fully implemented.
522 Still give the possibility to force the use of Heimdal, but with
523 warnings and a request that patches get sent to openssl-dev.
526 *) Add the VC-CE target, introduce the WINCE sysname, and add
527 INSTALL.WCE and appropriate conditionals to make it build.
528 [Steven Reddie <smr@essemer.com.au> via Richard Levitte]
530 *) Change the DLL names for Cygwin to cygcrypto-x.y.z.dll and
531 cygssl-x.y.z.dll, where x, y and z are the major, minor and
532 edit numbers of the version.
533 [Corinna Vinschen <vinschen@redhat.com> and Richard Levitte]
535 *) Introduce safe string copy and catenation functions
536 (BUF_strlcpy() and BUF_strlcat()).
537 [Ben Laurie (CHATS) and Richard Levitte]
539 *) Avoid using fixed-size buffers for one-line DNs.
542 *) Add BUF_MEM_grow_clean() to avoid information leakage when
543 resizing buffers containing secrets, and use where appropriate.
546 *) Avoid using fixed size buffers for configuration file location.
549 *) Avoid filename truncation for various CA files.
552 *) Use sizeof in preference to magic numbers.
555 *) Avoid filename truncation in cert requests.
558 *) Add assertions to check for (supposedly impossible) buffer
562 *) Don't cache truncated DNS entries in the local cache (this could
563 potentially lead to a spoofing attack).
566 *) Fix various buffers to be large enough for hex/decimal
567 representations in a platform independent manner.
570 *) Add CRYPTO_realloc_clean() to avoid information leakage when
571 resizing buffers containing secrets, and use where appropriate.
574 *) Add BIO_indent() to avoid much slightly worrying code to do
578 *) Convert sprintf()/BIO_puts() to BIO_printf().
581 *) buffer_gets() could terminate with the buffer only half
585 *) Add assertions to prevent user-supplied crypto functions from
586 overflowing internal buffers by having large block sizes, etc.
589 *) New OPENSSL_assert() macro (similar to assert(), but enabled
593 *) Eliminate unused copy of key in RC4.
596 *) Eliminate unused and incorrectly sized buffers for IV in pem.h.
599 *) Fix off-by-one error in EGD path.
602 *) If RANDFILE path is too long, ignore instead of truncating.
605 *) Eliminate unused and incorrectly sized X.509 structure
609 *) Eliminate unused and dangerous function knumber().
612 *) Eliminate unused and dangerous structure, KSSL_ERR.
615 *) Protect against overlong session ID context length in an encoded
616 session object. Since these are local, this does not appear to be
620 *) Change from security patch (see 0.9.6e below) that did not affect
621 the 0.9.6 release series:
623 Remote buffer overflow in SSL3 protocol - an attacker could
624 supply an oversized master key in Kerberos-enabled versions.
628 *) Change the SSL kerb5 codes to match RFC 2712.
631 *) Make -nameopt work fully for req and add -reqopt switch.
632 [Michael Bell <michael.bell@rz.hu-berlin.de>, Steve Henson]
634 *) The "block size" for block ciphers in CFB and OFB mode should be 1.
635 [Steve Henson, reported by Yngve Nysaeter Pettersen <yngve@opera.com>]
637 *) Make sure tests can be performed even if the corresponding algorithms
638 have been removed entirely. This was also the last step to make
639 OpenSSL compilable with DJGPP under all reasonable conditions.
640 [Richard Levitte, Doug Kaufman <dkaufman@rahul.net>]
642 *) Add cipher selection rules COMPLEMENTOFALL and COMPLEMENTOFDEFAULT
643 to allow version independent disabling of normally unselected ciphers,
644 which may be activated as a side-effect of selecting a single cipher.
646 (E.g., cipher list string "RSA" enables ciphersuites that are left
647 out of "ALL" because they do not provide symmetric encryption.
648 "RSA:!COMPLEMEMENTOFALL" avoids these unsafe ciphersuites.)
649 [Lutz Jaenicke, Bodo Moeller]
651 *) Add appropriate support for separate platform-dependent build
652 directories. The recommended way to make a platform-dependent
653 build directory is the following (tested on Linux), maybe with
656 # Place yourself outside of the OpenSSL source tree. In
657 # this example, the environment variable OPENSSL_SOURCE
658 # is assumed to contain the absolute OpenSSL source directory.
659 mkdir -p objtree/"`uname -s`-`uname -r`-`uname -m`"
660 cd objtree/"`uname -s`-`uname -r`-`uname -m`"
661 (cd $OPENSSL_SOURCE; find . -type f) | while read F; do
662 mkdir -p `dirname $F`
663 ln -s $OPENSSL_SOURCE/$F $F
666 To be absolutely sure not to disturb the source tree, a "make clean"
667 is a good thing. If it isn't successfull, don't worry about it,
668 it probably means the source directory is very clean.
671 *) Make sure any ENGINE control commands make local copies of string
672 pointers passed to them whenever necessary. Otherwise it is possible
673 the caller may have overwritten (or deallocated) the original string
674 data when a later ENGINE operation tries to use the stored values.
675 [Götz Babin-Ebell <babinebell@trustcenter.de>]
677 *) Improve diagnostics in file reading and command-line digests.
678 [Ben Laurie aided and abetted by Solar Designer <solar@openwall.com>]
680 *) Add AES modes CFB and OFB to the object database. Correct an
681 error in AES-CFB decryption.
684 *) Remove most calls to EVP_CIPHER_CTX_cleanup() in evp_enc.c, this
685 allows existing EVP_CIPHER_CTX structures to be reused after
686 calling EVP_*Final(). This behaviour is used by encryption
687 BIOs and some applications. This has the side effect that
688 applications must explicitly clean up cipher contexts with
689 EVP_CIPHER_CTX_cleanup() or they will leak memory.
692 *) Check the values of dna and dnb in bn_mul_recursive before calling
693 bn_mul_comba (a non zero value means the a or b arrays do not contain
694 n2 elements) and fallback to bn_mul_normal if either is not zero.
697 *) Fix escaping of non-ASCII characters when using the -subj option
698 of the "openssl req" command line tool. (Robert Joop <joop@fokus.gmd.de>)
701 *) Make object definitions compliant to LDAP (RFC2256): SN is the short
702 form for "surname", serialNumber has no short form.
703 Use "mail" as the short name for "rfc822Mailbox" according to RFC2798;
704 therefore remove "mail" short name for "internet 7".
705 The OID for unique identifiers in X509 certificates is
706 x500UniqueIdentifier, not uniqueIdentifier.
707 Some more OID additions. (Michael Bell <michael.bell@rz.hu-berlin.de>)
710 *) Add an "init" command to the ENGINE config module and auto initialize
711 ENGINEs. Without any "init" command the ENGINE will be initialized
712 after all ctrl commands have been executed on it. If init=1 the
713 ENGINE is initailized at that point (ctrls before that point are run
714 on the uninitialized ENGINE and after on the initialized one). If
715 init=0 then the ENGINE will not be iniatialized at all.
718 *) Fix the 'app_verify_callback' interface so that the user-defined
719 argument is actually passed to the callback: In the
720 SSL_CTX_set_cert_verify_callback() prototype, the callback
721 declaration has been changed from
724 int (*cb)(X509_STORE_CTX *,void *);
725 in ssl_verify_cert_chain (ssl/ssl_cert.c), the call
726 i=s->ctx->app_verify_callback(&ctx)
727 has been changed into
728 i=s->ctx->app_verify_callback(&ctx, s->ctx->app_verify_arg).
730 To update applications using SSL_CTX_set_cert_verify_callback(),
731 a dummy argument can be added to their callback functions.
732 [D. K. Smetters <smetters@parc.xerox.com>]
734 *) Added the '4758cca' ENGINE to support IBM 4758 cards.
735 [Maurice Gittens <maurice@gittens.nl>, touchups by Geoff Thorpe]
737 *) Add and OPENSSL_LOAD_CONF define which will cause
738 OpenSSL_add_all_algorithms() to load the openssl.cnf config file.
739 This allows older applications to transparently support certain
740 OpenSSL features: such as crypto acceleration and dynamic ENGINE loading.
741 Two new functions OPENSSL_add_all_algorithms_noconf() which will never
742 load the config file and OPENSSL_add_all_algorithms_conf() which will
743 always load it have also been added.
746 *) Add the OFB, CFB and CTR (all with 128 bit feedback) to AES.
747 Adjust NIDs and EVP layer.
748 [Stephen Sprunk <stephen@sprunk.org> and Richard Levitte]
750 *) Config modules support in openssl utility.
752 Most commands now load modules from the config file,
753 though in a few (such as version) this isn't done
754 because it couldn't be used for anything.
756 In the case of ca and req the config file used is
757 the same as the utility itself: that is the -config
758 command line option can be used to specify an
762 *) Move default behaviour from OPENSSL_config(). If appname is NULL
763 use "openssl_conf" if filename is NULL use default openssl config file.
766 *) Add an argument to OPENSSL_config() to allow the use of an alternative
767 config section name. Add a new flag to tolerate a missing config file
768 and move code to CONF_modules_load_file().
771 *) Support for crypto accelerator cards from Accelerated Encryption
772 Processing, www.aep.ie. (Use engine 'aep')
773 The support was copied from 0.9.6c [engine] and adapted/corrected
774 to work with the new engine framework.
775 [AEP Inc. and Richard Levitte]
777 *) Support for SureWare crypto accelerator cards from Baltimore
778 Technologies. (Use engine 'sureware')
779 The support was copied from 0.9.6c [engine] and adapted
780 to work with the new engine framework.
783 *) Have the CHIL engine fork-safe (as defined by nCipher) and actually
784 make the newer ENGINE framework commands for the CHIL engine work.
785 [Toomas Kiisk <vix@cyber.ee> and Richard Levitte]
787 *) Make it possible to produce shared libraries on ReliantUNIX.
788 [Robert Dahlem <Robert.Dahlem@ffm2.siemens.de> via Richard Levitte]
790 *) Add the configuration target debug-linux-ppro.
791 Make 'openssl rsa' use the general key loading routines
792 implemented in apps.c, and make those routines able to
793 handle the key format FORMAT_NETSCAPE and the variant
795 [Toomas Kiisk <vix@cyber.ee> via Richard Levitte]
797 *) Fix a crashbug and a logic bug in hwcrhk_load_pubkey().
798 [Toomas Kiisk <vix@cyber.ee> via Richard Levitte]
800 *) Add -keyform to rsautl, and document -engine.
801 [Richard Levitte, inspired by Toomas Kiisk <vix@cyber.ee>]
803 *) Change BIO_new_file (crypto/bio/bss_file.c) to use new
804 BIO_R_NO_SUCH_FILE error code rather than the generic
805 ERR_R_SYS_LIB error code if fopen() fails with ENOENT.
810 ERR_peek_last_error_line
811 ERR_peek_last_error_line_data.
815 ERR_peek_error_line_data,
816 but report on the latest error recorded rather than the first one
817 still in the error queue.
818 [Ben Laurie, Bodo Moeller]
820 *) default_algorithms option in ENGINE config module. This allows things
822 default_algorithms = ALL
823 default_algorithms = RSA, DSA, RAND, CIPHERS, DIGESTS
826 *) Prelminary ENGINE config module.
829 *) New experimental application configuration code.
832 *) Change the AES code to follow the same name structure as all other
833 symmetric ciphers, and behave the same way. Move everything to
834 the directory crypto/aes, thereby obsoleting crypto/rijndael.
835 [Stephen Sprunk <stephen@sprunk.org> and Richard Levitte]
837 *) SECURITY: remove unsafe setjmp/signal interaction from ui_openssl.c.
838 [Ben Laurie and Theo de Raadt]
840 *) Add option to output public keys in req command.
841 [Massimiliano Pala madwolf@openca.org]
843 *) Use wNAFs in EC_POINTs_mul() for improved efficiency
844 (up to about 10% better than before for P-192 and P-224).
847 *) New functions/macros
849 SSL_CTX_set_msg_callback(ctx, cb)
850 SSL_CTX_set_msg_callback_arg(ctx, arg)
851 SSL_set_msg_callback(ssl, cb)
852 SSL_set_msg_callback_arg(ssl, arg)
854 to request calling a callback function
856 void cb(int write_p, int version, int content_type,
857 const void *buf, size_t len, SSL *ssl, void *arg)
859 whenever a protocol message has been completely received
860 (write_p == 0) or sent (write_p == 1). Here 'version' is the
861 protocol version according to which the SSL library interprets
862 the current protocol message (SSL2_VERSION, SSL3_VERSION, or
863 TLS1_VERSION). 'content_type' is 0 in the case of SSL 2.0, or
864 the content type as defined in the SSL 3.0/TLS 1.0 protocol
865 specification (change_cipher_spec(20), alert(21), handshake(22)).
866 'buf' and 'len' point to the actual message, 'ssl' to the
867 SSL object, and 'arg' is the application-defined value set by
868 SSL[_CTX]_set_msg_callback_arg().
870 'openssl s_client' and 'openssl s_server' have new '-msg' options
871 to enable a callback that displays all protocol messages.
874 *) Change the shared library support so shared libraries are built as
875 soon as the corresponding static library is finished, and thereby get
876 openssl and the test programs linked against the shared library.
877 This still only happens when the keyword "shard" has been given to
878 the configuration scripts.
880 NOTE: shared library support is still an experimental thing, and
881 backward binary compatibility is still not guaranteed.
882 ["Maciej W. Rozycki" <macro@ds2.pg.gda.pl> and Richard Levitte]
884 *) Add support for Subject Information Access extension.
885 [Peter Sylvester <Peter.Sylvester@EdelWeb.fr>]
887 *) Make BUF_MEM_grow() behaviour more consistent: Initialise to zero
888 additional bytes when new memory had to be allocated, not just
889 when reusing an existing buffer.
892 *) New command line and configuration option 'utf8' for the req command.
893 This allows field values to be specified as UTF8 strings.
896 *) Add -multi and -mr options to "openssl speed" - giving multiple parallel
897 runs for the former and machine-readable output for the latter.
900 *) Add '-noemailDN' option to 'openssl ca'. This prevents inclusion
901 of the e-mail address in the DN (i.e., it will go into a certificate
902 extension only). The new configuration file option 'email_in_dn = no'
904 [Massimiliano Pala madwolf@openca.org]
906 *) Change all functions with names starting with des_ to be starting
907 with DES_ instead. Add wrappers that are compatible with libdes,
908 but are named _ossl_old_des_*. Finally, add macros that map the
909 des_* symbols to the corresponding _ossl_old_des_* if libdes
910 compatibility is desired. If OpenSSL 0.9.6c compatibility is
911 desired, the des_* symbols will be mapped to DES_*, with one
914 Since we provide two compatibility mappings, the user needs to
915 define the macro OPENSSL_DES_LIBDES_COMPATIBILITY if libdes
916 compatibility is desired. The default (i.e., when that macro
917 isn't defined) is OpenSSL 0.9.6c compatibility.
919 There are also macros that enable and disable the support of old
920 des functions altogether. Those are OPENSSL_ENABLE_OLD_DES_SUPPORT
921 and OPENSSL_DISABLE_OLD_DES_SUPPORT. If none or both of those
922 are defined, the default will apply: to support the old des routines.
924 In either case, one must include openssl/des.h to get the correct
925 definitions. Do not try to just include openssl/des_old.h, that
928 NOTE: This is a major break of an old API into a new one. Software
929 authors are encouraged to switch to the DES_ style functions. Some
930 time in the future, des_old.h and the libdes compatibility functions
931 will be disable (i.e. OPENSSL_DISABLE_OLD_DES_SUPPORT will be the
932 default), and then completely removed.
935 *) Test for certificates which contain unsupported critical extensions.
936 If such a certificate is found during a verify operation it is
937 rejected by default: this behaviour can be overridden by either
938 handling the new error X509_V_ERR_UNHANDLED_CRITICAL_EXTENSION or
939 by setting the verify flag X509_V_FLAG_IGNORE_CRITICAL. A new function
940 X509_supported_extension() has also been added which returns 1 if a
941 particular extension is supported.
944 *) Modify the behaviour of EVP cipher functions in similar way to digests
945 to retain compatibility with existing code.
948 *) Modify the behaviour of EVP_DigestInit() and EVP_DigestFinal() to retain
949 compatibility with existing code. In particular the 'ctx' parameter does
950 not have to be to be initialized before the call to EVP_DigestInit() and
951 it is tidied up after a call to EVP_DigestFinal(). New function
952 EVP_DigestFinal_ex() which does not tidy up the ctx. Similarly function
953 EVP_MD_CTX_copy() changed to not require the destination to be
954 initialized valid and new function EVP_MD_CTX_copy_ex() added which
955 requires the destination to be valid.
957 Modify all the OpenSSL digest calls to use EVP_DigestInit_ex(),
958 EVP_DigestFinal_ex() and EVP_MD_CTX_copy_ex().
961 *) Change ssl3_get_message (ssl/s3_both.c) and the functions using it
962 so that complete 'Handshake' protocol structures are kept in memory
963 instead of overwriting 'msg_type' and 'length' with 'body' data.
966 *) Add an implementation of SSL_add_dir_cert_subjects_to_stack for Win32.
967 [Massimo Santin via Richard Levitte]
969 *) Major restructuring to the underlying ENGINE code. This includes
970 reduction of linker bloat, separation of pure "ENGINE" manipulation
971 (initialisation, etc) from functionality dealing with implementations
972 of specific crypto iterfaces. This change also introduces integrated
973 support for symmetric ciphers and digest implementations - so ENGINEs
974 can now accelerate these by providing EVP_CIPHER and EVP_MD
975 implementations of their own. This is detailed in crypto/engine/README
976 as it couldn't be adequately described here. However, there are a few
977 API changes worth noting - some RSA, DSA, DH, and RAND functions that
978 were changed in the original introduction of ENGINE code have now
979 reverted back - the hooking from this code to ENGINE is now a good
980 deal more passive and at run-time, operations deal directly with
981 RSA_METHODs, DSA_METHODs (etc) as they did before, rather than
982 dereferencing through an ENGINE pointer any more. Also, the ENGINE
983 functions dealing with BN_MOD_EXP[_CRT] handlers have been removed -
984 they were not being used by the framework as there is no concept of a
985 BIGNUM_METHOD and they could not be generalised to the new
986 'ENGINE_TABLE' mechanism that underlies the new code. Similarly,
987 ENGINE_cpy() has been removed as it cannot be consistently defined in
991 *) Change ASN1_GENERALIZEDTIME_check() to allow fractional seconds.
994 *) Change mkdef.pl to sort symbols that get the same entry number,
995 and make sure the automatically generated functions ERR_load_*
996 become part of libeay.num as well.
999 *) New function SSL_renegotiate_pending(). This returns true once
1000 renegotiation has been requested (either SSL_renegotiate() call
1001 or HelloRequest/ClientHello receveived from the peer) and becomes
1002 false once a handshake has been completed.
1003 (For servers, SSL_renegotiate() followed by SSL_do_handshake()
1004 sends a HelloRequest, but does not ensure that a handshake takes
1005 place. SSL_renegotiate_pending() is useful for checking if the
1006 client has followed the request.)
1009 *) New SSL option SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION.
1010 By default, clients may request session resumption even during
1011 renegotiation (if session ID contexts permit); with this option,
1012 session resumption is possible only in the first handshake.
1014 SSL_OP_ALL is now 0x00000FFFL instead of 0x000FFFFFL. This makes
1015 more bits available for options that should not be part of
1016 SSL_OP_ALL (such as SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION).
1019 *) Add some demos for certificate and certificate request creation.
1022 *) Make maximum certificate chain size accepted from the peer application
1023 settable (SSL*_get/set_max_cert_list()), as proposed by
1024 "Douglas E. Engert" <deengert@anl.gov>.
1027 *) Add support for shared libraries for Unixware-7
1028 (Boyd Lynn Gerber <gerberb@zenez.com>).
1031 *) Add a "destroy" handler to ENGINEs that allows structural cleanup to
1032 be done prior to destruction. Use this to unload error strings from
1033 ENGINEs that load their own error strings. NB: This adds two new API
1034 functions to "get" and "set" this destroy handler in an ENGINE.
1037 *) Alter all existing ENGINE implementations (except "openssl" and
1038 "openbsd") to dynamically instantiate their own error strings. This
1039 makes them more flexible to be built both as statically-linked ENGINEs
1040 and self-contained shared-libraries loadable via the "dynamic" ENGINE.
1041 Also, add stub code to each that makes building them as self-contained
1042 shared-libraries easier (see README.ENGINE).
1045 *) Add a "dynamic" ENGINE that provides a mechanism for binding ENGINE
1046 implementations into applications that are completely implemented in
1047 self-contained shared-libraries. The "dynamic" ENGINE exposes control
1048 commands that can be used to configure what shared-library to load and
1049 to control aspects of the way it is handled. Also, made an update to
1050 the README.ENGINE file that brings its information up-to-date and
1051 provides some information and instructions on the "dynamic" ENGINE
1052 (ie. how to use it, how to build "dynamic"-loadable ENGINEs, etc).
1055 *) Make it possible to unload ranges of ERR strings with a new
1056 "ERR_unload_strings" function.
1059 *) Add a copy() function to EVP_MD.
1062 *) Make EVP_MD routines take a context pointer instead of just the
1063 md_data void pointer.
1066 *) Add flags to EVP_MD and EVP_MD_CTX. EVP_MD_FLAG_ONESHOT indicates
1067 that the digest can only process a single chunk of data
1068 (typically because it is provided by a piece of
1069 hardware). EVP_MD_CTX_FLAG_ONESHOT indicates that the application
1070 is only going to provide a single chunk of data, and hence the
1071 framework needn't accumulate the data for oneshot drivers.
1074 *) As with "ERR", make it possible to replace the underlying "ex_data"
1075 functions. This change also alters the storage and management of global
1076 ex_data state - it's now all inside ex_data.c and all "class" code (eg.
1077 RSA, BIO, SSL_CTX, etc) no longer stores its own STACKS and per-class
1078 index counters. The API functions that use this state have been changed
1079 to take a "class_index" rather than pointers to the class's local STACK
1080 and counter, and there is now an API function to dynamically create new
1081 classes. This centralisation allows us to (a) plug a lot of the
1082 thread-safety problems that existed, and (b) makes it possible to clean
1083 up all allocated state using "CRYPTO_cleanup_all_ex_data()". W.r.t. (b)
1084 such data would previously have always leaked in application code and
1085 workarounds were in place to make the memory debugging turn a blind eye
1086 to it. Application code that doesn't use this new function will still
1087 leak as before, but their memory debugging output will announce it now
1088 rather than letting it slide.
1090 Besides the addition of CRYPTO_cleanup_all_ex_data(), another API change
1091 induced by the "ex_data" overhaul is that X509_STORE_CTX_init() now
1092 has a return value to indicate success or failure.
1095 *) Make it possible to replace the underlying "ERR" functions such that the
1096 global state (2 LHASH tables and 2 locks) is only used by the "default"
1097 implementation. This change also adds two functions to "get" and "set"
1098 the implementation prior to it being automatically set the first time
1099 any other ERR function takes place. Ie. an application can call "get",
1100 pass the return value to a module it has just loaded, and that module
1101 can call its own "set" function using that value. This means the
1102 module's "ERR" operations will use (and modify) the error state in the
1103 application and not in its own statically linked copy of OpenSSL code.
1106 *) Give DH, DSA, and RSA types their own "**_up_ref()" function to increment
1107 reference counts. This performs normal REF_PRINT/REF_CHECK macros on
1108 the operation, and provides a more encapsulated way for external code
1109 (crypto/evp/ and ssl/) to do this. Also changed the evp and ssl code
1110 to use these functions rather than manually incrementing the counts.
1112 Also rename "DSO_up()" function to more descriptive "DSO_up_ref()".
1115 *) Add EVP test program.
1118 *) Add symmetric cipher support to ENGINE. Expect the API to change!
1121 *) New CRL functions: X509_CRL_set_version(), X509_CRL_set_issuer_name()
1122 X509_CRL_set_lastUpdate(), X509_CRL_set_nextUpdate(), X509_CRL_sort(),
1123 X509_REVOKED_set_serialNumber(), and X509_REVOKED_set_revocationDate().
1124 These allow a CRL to be built without having to access X509_CRL fields
1125 directly. Modify 'ca' application to use new functions.
1128 *) Move SSL_OP_TLS_ROLLBACK_BUG out of the SSL_OP_ALL list of recommended
1129 bug workarounds. Rollback attack detection is a security feature.
1130 The problem will only arise on OpenSSL servers when TLSv1 is not
1131 available (sslv3_server_method() or SSL_OP_NO_TLSv1).
1132 Software authors not wanting to support TLSv1 will have special reasons
1133 for their choice and can explicitly enable this option.
1134 [Bodo Moeller, Lutz Jaenicke]
1136 *) Rationalise EVP so it can be extended: don't include a union of
1137 cipher/digest structures, add init/cleanup functions for EVP_MD_CTX
1138 (similar to those existing for EVP_CIPHER_CTX).
1143 EVP_MD_CTX_init(&md); /* new function call */
1144 EVP_DigestInit(&md, EVP_sha1());
1145 EVP_DigestUpdate(&md, in, len);
1146 EVP_DigestFinal(&md, out, NULL);
1147 EVP_MD_CTX_cleanup(&md); /* new function call */
1151 *) Make DES key schedule conform to the usual scheme, as well as
1152 correcting its structure. This means that calls to DES functions
1153 now have to pass a pointer to a des_key_schedule instead of a
1154 plain des_key_schedule (which was actually always a pointer
1157 des_key_schedule ks;
1159 des_set_key_checked(..., &ks);
1160 des_ncbc_encrypt(..., &ks, ...);
1162 (Note that a later change renames 'des_...' into 'DES_...'.)
1165 *) Initial reduction of linker bloat: the use of some functions, such as
1166 PEM causes large amounts of unused functions to be linked in due to
1167 poor organisation. For example pem_all.c contains every PEM function
1168 which has a knock on effect of linking in large amounts of (unused)
1169 ASN1 code. Grouping together similar functions and splitting unrelated
1170 functions prevents this.
1173 *) Cleanup of EVP macros.
1176 *) Change historical references to {NID,SN,LN}_des_ede and ede3 to add the
1177 correct _ecb suffix.
1180 *) Add initial OCSP responder support to ocsp application. The
1181 revocation information is handled using the text based index
1182 use by the ca application. The responder can either handle
1183 requests generated internally, supplied in files (for example
1184 via a CGI script) or using an internal minimal server.
1187 *) Add configuration choices to get zlib compression for TLS.
1190 *) Changes to Kerberos SSL for RFC 2712 compliance:
1191 1. Implemented real KerberosWrapper, instead of just using
1192 KRB5 AP_REQ message. [Thanks to Simon Wilkinson <sxw@sxw.org.uk>]
1193 2. Implemented optional authenticator field of KerberosWrapper.
1195 Added openssl-style ASN.1 macros for Kerberos ticket, ap_req,
1196 and authenticator structs; see crypto/krb5/.
1198 Generalized Kerberos calls to support multiple Kerberos libraries.

1200 Jeffrey Altman <jaltman@columbia.edu>
1201 via Richard Levitte]
1203 *) Cause 'openssl speed' to use fully hard-coded DSA keys as it
1204 already does with RSA. testdsa.h now has 'priv_key/pub_key'
1205 values for each of the key sizes rather than having just
1206 parameters (and 'speed' generating keys each time).
1209 *) Speed up EVP routines.

1227 *) Added the OS2-EMX target.
1228 ["Brian Havard" <brianh@kheldar.apana.org.au> and Richard Levitte]
1230 *) Rewrite apps to use NCONF routines instead of the old CONF. New functions
1231 to support NCONF routines in extension code. New function CONF_set_nconf()
1232 to allow functions which take an NCONF to also handle the old LHASH
1233 structure: this means that the old CONF compatible routines can be
1234 retained (in particular wrt extensions) without having to duplicate the
1235 code. New function X509V3_add_ext_nconf_sk to add extensions to a stack.
1238 *) Enhance the general user interface with mechanisms for inner control
1239 and with possibilities to have yes/no kind of prompts.
1242 *) Change all calls to low level digest routines in the library and
1243 applications to use EVP. Add missing calls to HMAC_cleanup() and
1244 don't assume HMAC_CTX can be copied using memcpy().
1245 [Verdon Walker <VWalker@novell.com>, Steve Henson]
1247 *) Add the possibility to control engines through control names but with
1248 arbitrary arguments instead of just a string.
1249 Change the key loaders to take a UI_METHOD instead of a callback
1250 function pointer. NOTE: this breaks binary compatibility with earlier
1251 versions of OpenSSL [engine].
1252 Adapt the nCipher code for these new conditions and add a card insertion
1256 *) Enhance the general user interface with mechanisms to better support
1257 dialog box interfaces, application-defined prompts, the possibility
1258 to use defaults (for example default passwords from somewhere else)
1259 and interrupts/cancellations.
1262 *) Tidy up PKCS#12 attribute handling. Add support for the CSP name
1263 attribute in PKCS#12 files, add new -CSP option to pkcs12 utility.
1266 *) Fix a memory leak in 'sk_dup()' in the case reallocation fails. (Also
1267 tidy up some unnecessarily weird code in 'sk_new()').
1268 [Geoff, reported by Diego Tartara <dtartara@novamens.com>]
1270 *) Change the key loading routines for ENGINEs to use the same kind
1271 callback (pem_password_cb) as all other routines that need this
1275 *) Increase ENTROPY_NEEDED to 32 bytes, as Rijndael can operate with
1276 256 bit (=32 byte) keys. Of course seeding with more entropy bytes
1277 than this minimum value is recommended.
1280 *) New random seeder for OpenVMS, using the system process statistics
1281 that are easily reachable.
1284 *) Windows apparently can't transparently handle global
1285 variables defined in DLLs. Initialisations such as:
1287 const ASN1_ITEM *it = &ASN1_INTEGER_it;
1289 wont compile. This is used by the any applications that need to
1290 declare their own ASN1 modules. This was fixed by adding the option
1291 EXPORT_VAR_AS_FN to all Win32 platforms, although this isn't strictly
1292 needed for static libraries under Win32.
1295 *) New functions X509_PURPOSE_set() and X509_TRUST_set() to handle
1296 setting of purpose and trust fields. New X509_STORE trust and
1297 purpose functions and tidy up setting in other SSL functions.
1300 *) Add copies of X509_STORE_CTX fields and callbacks to X509_STORE
1301 structure. These are inherited by X509_STORE_CTX when it is
1302 initialised. This allows various defaults to be set in the
1303 X509_STORE structure (such as flags for CRL checking and custom
1304 purpose or trust settings) for functions which only use X509_STORE_CTX
1305 internally such as S/MIME.
1307 Modify X509_STORE_CTX_purpose_inherit() so it only sets purposes and
1308 trust settings if they are not set in X509_STORE. This allows X509_STORE
1309 purposes and trust (in S/MIME for example) to override any set by default.
1311 Add command line options for CRL checking to smime, s_client and s_server
1315 *) Initial CRL based revocation checking. If the CRL checking flag(s)
1316 are set then the CRL is looked up in the X509_STORE structure and
1317 its validity and signature checked, then if the certificate is found
1318 in the CRL the verify fails with a revoked error.
1320 Various new CRL related callbacks added to X509_STORE_CTX structure.
1322 Command line options added to 'verify' application to support this.
1324 This needs some additional work, such as being able to handle multiple
1325 CRLs with different times, extension based lookup (rather than just
1326 by subject name) and ultimately more complete V2 CRL extension
1330 *) Add a general user interface API (crypto/ui/). This is designed
1331 to replace things like des_read_password and friends (backward
1332 compatibility functions using this new API are provided).
1333 The purpose is to remove prompting functions from the DES code
1334 section as well as provide for prompting through dialog boxes in
1335 a window system and the like.
1338 *) Add "ex_data" support to ENGINE so implementations can add state at a
1339 per-structure level rather than having to store it globally.
1342 *) Make it possible for ENGINE structures to be copied when retrieved by
1343 ENGINE_by_id() if the ENGINE specifies a new flag: ENGINE_FLAGS_BY_ID_COPY.
1344 This causes the "original" ENGINE structure to act like a template,
1345 analogous to the RSA vs. RSA_METHOD type of separation. Because of this
1346 operational state can be localised to each ENGINE structure, despite the
1347 fact they all share the same "methods". New ENGINE structures returned in
1348 this case have no functional references and the return value is the single
1349 structural reference. This matches the single structural reference returned
1350 by ENGINE_by_id() normally, when it is incremented on the pre-existing
1354 *) Fix ASN1 decoder when decoding type ANY and V_ASN1_OTHER: since this
1355 needs to match any other type at all we need to manually clear the
1359 *) Changes to the "openssl engine" utility to include;
1360 - verbosity levels ('-v', '-vv', and '-vvv') that provide information
1361 about an ENGINE's available control commands.
1362 - executing control commands from command line arguments using the
1363 '-pre' and '-post' switches. '-post' is only used if '-t' is
1364 specified and the ENGINE is successfully initialised. The syntax for
1365 the individual commands are colon-separated, for example;
1366 openssl engine chil -pre FORK_CHECK:0 -pre SO_PATH:/lib/test.so
1369 *) New dynamic control command support for ENGINEs. ENGINEs can now
1370 declare their own commands (numbers), names (strings), descriptions,
1371 and input types for run-time discovery by calling applications. A
1372 subset of these commands are implicitly classed as "executable"
1373 depending on their input type, and only these can be invoked through
1374 the new string-based API function ENGINE_ctrl_cmd_string(). (Eg. this
1375 can be based on user input, config files, etc). The distinction is
1376 that "executable" commands cannot return anything other than a boolean
1377 result and can only support numeric or string input, whereas some
1378 discoverable commands may only be for direct use through
1379 ENGINE_ctrl(), eg. supporting the exchange of binary data, function
1380 pointers, or other custom uses. The "executable" commands are to
1381 support parameterisations of ENGINE behaviour that can be
1382 unambiguously defined by ENGINEs and used consistently across any
1383 OpenSSL-based application. Commands have been added to all the
1384 existing hardware-supporting ENGINEs, noticeably "SO_PATH" to allow
1385 control over shared-library paths without source code alterations.
1388 *) Changed all ENGINE implementations to dynamically allocate their
1389 ENGINEs rather than declaring them statically. Apart from this being
1390 necessary with the removal of the ENGINE_FLAGS_MALLOCED distinction,
1391 this also allows the implementations to compile without using the
1392 internal engine_int.h header.
1395 *) Minor adjustment to "rand" code. RAND_get_rand_method() now returns a
1396 'const' value. Any code that should be able to modify a RAND_METHOD
1397 should already have non-const pointers to it (ie. they should only
1398 modify their own ones).
1401 *) Made a variety of little tweaks to the ENGINE code.
1402 - "atalla" and "ubsec" string definitions were moved from header files
1403 to C code. "nuron" string definitions were placed in variables
1404 rather than hard-coded - allowing parameterisation of these values
1405 later on via ctrl() commands.
1406 - Removed unused "#if 0"'d code.
1407 - Fixed engine list iteration code so it uses ENGINE_free() to release
1408 structural references.
1409 - Constified the RAND_METHOD element of ENGINE structures.
1410 - Constified various get/set functions as appropriate and added
1411 missing functions (including a catch-all ENGINE_cpy that duplicates
1412 all ENGINE values onto a new ENGINE except reference counts/state).
1413 - Removed NULL parameter checks in get/set functions. Setting a method
1414 or function to NULL is a way of cancelling out a previously set
1415 value. Passing a NULL ENGINE parameter is just plain stupid anyway
1416 and doesn't justify the extra error symbols and code.
1417 - Deprecate the ENGINE_FLAGS_MALLOCED define and move the area for
1418 flags from engine_int.h to engine.h.
1419 - Changed prototypes for ENGINE handler functions (init(), finish(),
1420 ctrl(), key-load functions, etc) to take an (ENGINE*) parameter.
1423 *) Implement binary inversion algorithm for BN_mod_inverse in addition
1424 to the algorithm using long division. The binary algorithm can be
1425 used only if the modulus is odd. On 32-bit systems, it is faster
1426 only for relatively small moduli (roughly 20-30% for 128-bit moduli,
1427 roughly 5-15% for 256-bit moduli), so we use it only for moduli
1428 up to 450 bits. In 64-bit environments, the binary algorithm
1429 appears to be advantageous for much longer moduli; here we use it
1430 for moduli up to 2048 bits.
1433 *) Rewrite CHOICE field setting in ASN1_item_ex_d2i(). The old code
1434 could not support the combine flag in choice fields.
1437 *) Add a 'copy_extensions' option to the 'ca' utility. This copies
1438 extensions from a certificate request to the certificate.
1441 *) Allow multiple 'certopt' and 'nameopt' options to be separated
1442 by commas. Add 'namopt' and 'certopt' options to the 'ca' config
1443 file: this allows the display of the certificate about to be
1444 signed to be customised, to allow certain fields to be included
1445 or excluded and extension details. The old system didn't display
1446 multicharacter strings properly, omitted fields not in the policy
1447 and couldn't display additional details such as extensions.
1450 *) Function EC_POINTs_mul for multiple scalar multiplication
1451 of an arbitrary number of elliptic curve points
1452 \sum scalars[i]*points[i],
1453 optionally including the generator defined for the EC_GROUP:
1454 scalar*generator + \sum scalars[i]*points[i].
1456 EC_POINT_mul is a simple wrapper function for the typical case
1457 that the point list has just one item (besides the optional
1461 *) First EC_METHODs for curves over GF(p):
1463 EC_GFp_simple_method() uses the basic BN_mod_mul and BN_mod_sqr
1464 operations and provides various method functions that can also
1465 operate with faster implementations of modular arithmetic.
1467 EC_GFp_mont_method() reuses most functions that are part of
1468 EC_GFp_simple_method, but uses Montgomery arithmetic.
1470 [Bodo Moeller; point addition and point doubling
1471 implementation directly derived from source code provided by
1472 Lenka Fibikova <fibikova@exp-math.uni-essen.de>]
1474 *) Framework for elliptic curves (crypto/ec/ec.h, crypto/ec/ec_lcl.h,
1475 crypto/ec/ec_lib.c):
1477 Curves are EC_GROUP objects (with an optional group generator)
1478 based on EC_METHODs that are built into the library.
1480 Points are EC_POINT objects based on EC_GROUP objects.
1482 Most of the framework would be able to handle curves over arbitrary
1483 finite fields, but as there are no obvious types for fields other
1484 than GF(p), some functions are limited to that for now.
1487 *) Add the -HTTP option to s_server. It is similar to -WWW, but requires
1488 that the file contains a complete HTTP response.
1491 *) Add the ec directory to mkdef.pl and mkfiles.pl. In mkdef.pl
1492 change the def and num file printf format specifier from "%-40sXXX"
1493 to "%-39s XXX". The latter will always guarantee a space after the
1494 field while the former will cause them to run together if the field
1495 is 40 of more characters long.
1498 *) Constify the cipher and digest 'method' functions and structures
1499 and modify related functions to take constant EVP_MD and EVP_CIPHER
1503 *) Hide BN_CTX structure details in bn_lcl.h instead of publishing them
1504 in <openssl/bn.h>. Also further increase BN_CTX_NUM to 32.
1507 *) Modify EVP_Digest*() routines so they now return values. Although the
1508 internal software routines can never fail additional hardware versions
1512 *) Clean up crypto/err/err.h and change some error codes to avoid conflicts:
1514 Previously ERR_R_FATAL was too small and coincided with ERR_LIB_PKCS7
1515 (= ERR_R_PKCS7_LIB); it is now 64 instead of 32.
1518 ERR_R_NESTED_ASN1_ERROR
1520 ERR_R_MISSING_ASN1_EOS
1521 were 4 .. 9, conflicting with
1522 ERR_LIB_RSA (= ERR_R_RSA_LIB)
1524 ERR_LIB_PEM (= ERR_R_PEM_LIB).
1525 They are now 58 .. 63 (i.e., just below ERR_R_FATAL).
1527 Add new error code 'ERR_R_INTERNAL_ERROR'.
1530 *) Don't overuse locks in crypto/err/err.c: For data retrieval, CRYPTO_r_lock
1534 *) New option '-subj arg' for 'openssl req' and 'openssl ca'. This
1535 sets the subject name for a new request or supersedes the
1536 subject name in a given request. Formats that can be parsed are
1537 'CN=Some Name, OU=myOU, C=IT'
1539 'CN=Some Name/OU=myOU/C=IT'.
1541 Add options '-batch' and '-verbose' to 'openssl req'.
1542 [Massimiliano Pala <madwolf@hackmasters.net>]
1544 *) Introduce the possibility to access global variables through
1545 functions on platform were that's the best way to handle exporting
1546 global variables in shared libraries. To enable this functionality,
1547 one must configure with "EXPORT_VAR_AS_FN" or defined the C macro
1548 "OPENSSL_EXPORT_VAR_AS_FUNCTION" in crypto/opensslconf.h (the latter
1549 is normally done by Configure or something similar).
1551 To implement a global variable, use the macro OPENSSL_IMPLEMENT_GLOBAL
1552 in the source file (foo.c) like this:
1554 OPENSSL_IMPLEMENT_GLOBAL(int,foo)=1;
1555 OPENSSL_IMPLEMENT_GLOBAL(double,bar);
1557 To declare a global variable, use the macros OPENSSL_DECLARE_GLOBAL
1558 and OPENSSL_GLOBAL_REF in the header file (foo.h) like this:
1560 OPENSSL_DECLARE_GLOBAL(int,foo);
1561 #define foo OPENSSL_GLOBAL_REF(foo)
1562 OPENSSL_DECLARE_GLOBAL(double,bar);
1563 #define bar OPENSSL_GLOBAL_REF(bar)
1565 The #defines are very important, and therefore so is including the
1566 header file everywhere where the defined globals are used.
1568 The macro OPENSSL_EXPORT_VAR_AS_FUNCTION also affects the definition
1569 of ASN.1 items, but that structure is a bit different.
1571 The largest change is in util/mkdef.pl which has been enhanced with
1572 better and easier to understand logic to choose which symbols should
1573 go into the Windows .def files as well as a number of fixes and code
1574 cleanup (among others, algorithm keywords are now sorted
1575 lexicographically to avoid constant rewrites).
1578 *) In BN_div() keep a copy of the sign of 'num' before writing the
1579 result to 'rm' because if rm==num the value will be overwritten
1580 and produce the wrong result if 'num' is negative: this caused
1581 problems with BN_mod() and BN_nnmod().
1584 *) Function OCSP_request_verify(). This checks the signature on an
1585 OCSP request and verifies the signer certificate. The signer
1586 certificate is just checked for a generic purpose and OCSP request
1590 *) Add OCSP_check_validity() function to check the validity of OCSP
1591 responses. OCSP responses are prepared in real time and may only
1592 be a few seconds old. Simply checking that the current time lies
1593 between thisUpdate and nextUpdate max reject otherwise valid responses
1594 caused by either OCSP responder or client clock inaccuracy. Instead
1595 we allow thisUpdate and nextUpdate to fall within a certain period of
1596 the current time. The age of the response can also optionally be
1597 checked. Two new options -validity_period and -status_age added to
1601 *) If signature or public key algorithm is unrecognized print out its
1602 OID rather that just UNKNOWN.
1605 *) Change OCSP_cert_to_id() to tolerate a NULL subject certificate and
1606 OCSP_cert_id_new() a NULL serialNumber. This allows a partial certificate
1607 ID to be generated from the issuer certificate alone which can then be
1608 passed to OCSP_id_issuer_cmp().
1611 *) New compilation option ASN1_ITEM_FUNCTIONS. This causes the new
1612 ASN1 modules to export functions returning ASN1_ITEM pointers
1613 instead of the ASN1_ITEM structures themselves. This adds several
1614 new macros which allow the underlying ASN1 function/structure to
1615 be accessed transparently. As a result code should not use ASN1_ITEM
1616 references directly (such as &X509_it) but instead use the relevant
1617 macros (such as ASN1_ITEM_rptr(X509)). This option is to allow
1618 use of the new ASN1 code on platforms where exporting structures
1619 is problematical (for example in shared libraries) but exporting
1620 functions returning pointers to structures is not.
1623 *) Add support for overriding the generation of SSL/TLS session IDs.
1624 These callbacks can be registered either in an SSL_CTX or per SSL.
1625 The purpose of this is to allow applications to control, if they wish,
1626 the arbitrary values chosen for use as session IDs, particularly as it
1627 can be useful for session caching in multiple-server environments. A
1628 command-line switch for testing this (and any client code that wishes
1629 to use such a feature) has been added to "s_server".
1630 [Geoff Thorpe, Lutz Jaenicke]
1632 *) Modify mkdef.pl to recognise and parse preprocessor conditionals
1633 of the form '#if defined(...) || defined(...) || ...' and
1634 '#if !defined(...) && !defined(...) && ...'. This also avoids
1635 the growing number of special cases it was previously handling.
1638 *) Make all configuration macros available for application by making
1639 sure they are available in opensslconf.h, by giving them names starting
1640 with "OPENSSL_" to avoid conflicts with other packages and by making
1641 sure e_os2.h will cover all platform-specific cases together with
1643 Additionally, it is now possible to define configuration/platform-
1644 specific names (called "system identities"). In the C code, these
1645 are prefixed with "OPENSSL_SYSNAME_". e_os2.h will create another
1646 macro with the name beginning with "OPENSSL_SYS_", which is determined
1647 from "OPENSSL_SYSNAME_*" or compiler-specific macros depending on
1651 *) New option -set_serial to 'req' and 'x509' this allows the serial
1652 number to use to be specified on the command line. Previously self
1653 signed certificates were hard coded with serial number 0 and the
1654 CA options of 'x509' had to use a serial number in a file which was
1658 *) New options to 'ca' utility to support V2 CRL entry extensions.
1659 Currently CRL reason, invalidity date and hold instruction are
1660 supported. Add new CRL extensions to V3 code and some new objects.
1663 *) New function EVP_CIPHER_CTX_set_padding() this is used to
1664 disable standard block padding (aka PKCS#5 padding) in the EVP
1665 API, which was previously mandatory. This means that the data is
1666 not padded in any way and so the total length much be a multiple
1667 of the block size, otherwise an error occurs.
1670 *) Initial (incomplete) OCSP SSL support.
1673 *) New function OCSP_parse_url(). This splits up a URL into its host,
1674 port and path components: primarily to parse OCSP URLs. New -url
1675 option to ocsp utility.
1678 *) New nonce behavior. The return value of OCSP_check_nonce() now
1679 reflects the various checks performed. Applications can decide
1680 whether to tolerate certain situations such as an absent nonce
1681 in a response when one was present in a request: the ocsp application
1682 just prints out a warning. New function OCSP_add1_basic_nonce()
1683 this is to allow responders to include a nonce in a response even if
1684 the request is nonce-less.
1687 *) Disable stdin buffering in load_cert (apps/apps.c) so that no certs are
1688 skipped when using openssl x509 multiple times on a single input file,
1689 e.g. "(openssl x509 -out cert1; openssl x509 -out cert2) <certs".
1692 *) Make ASN1_UTCTIME_set_string() and ASN1_GENERALIZEDTIME_set_string()
1693 set string type: to handle setting ASN1_TIME structures. Fix ca
1694 utility to correctly initialize revocation date of CRLs.
1697 *) New option SSL_OP_CIPHER_SERVER_PREFERENCE allows the server to override
1698 the clients preferred ciphersuites and rather use its own preferences.
1699 Should help to work around M$ SGC (Server Gated Cryptography) bug in
1700 Internet Explorer by ensuring unchanged hash method during stepup.
1701 (Also replaces the broken/deactivated SSL_OP_NON_EXPORT_FIRST option.)
1704 *) Make mkdef.pl recognise all DECLARE_ASN1 macros, change rijndael
1705 to aes and add a new 'exist' option to print out symbols that don't
1709 *) Additional options to ocsp utility to allow flags to be set and
1710 additional certificates supplied.
1713 *) Add the option -VAfile to 'openssl ocsp', so the user can give the
1714 OCSP client a number of certificate to only verify the response
1718 *) Update Rijndael code to version 3.0 and change EVP AES ciphers to
1719 handle the new API. Currently only ECB, CBC modes supported. Add new
1722 Add TLS AES ciphersuites as described in RFC3268, "Advanced
1723 Encryption Standard (AES) Ciphersuites for Transport Layer
1724 Security (TLS)". (In beta versions of OpenSSL 0.9.7, these were
1725 not enabled by default and were not part of the "ALL" ciphersuite
1726 alias because they were not yet official; they could be
1727 explicitly requested by specifying the "AESdraft" ciphersuite
1728 group alias. In the final release of OpenSSL 0.9.7, the group
1729 alias is called "AES" and is part of "ALL".)
1730 [Ben Laurie, Steve Henson, Bodo Moeller]
1732 *) New function OCSP_copy_nonce() to copy nonce value (if present) from
1733 request to response.
1736 *) Functions for OCSP responders. OCSP_request_onereq_count(),
1737 OCSP_request_onereq_get0(), OCSP_onereq_get0_id() and OCSP_id_get0_info()
1738 extract information from a certificate request. OCSP_response_create()
1739 creates a response and optionally adds a basic response structure.
1740 OCSP_basic_add1_status() adds a complete single response to a basic
1741 response and returns the OCSP_SINGLERESP structure just added (to allow
1742 extensions to be included for example). OCSP_basic_add1_cert() adds a
1743 certificate to a basic response and OCSP_basic_sign() signs a basic
1744 response with various flags. New helper functions ASN1_TIME_check()
1745 (checks validity of ASN1_TIME structure) and ASN1_TIME_to_generalizedtime()
1746 (converts ASN1_TIME to GeneralizedTime).
1749 *) Various new functions. EVP_Digest() combines EVP_Digest{Init,Update,Final}()
1750 in a single operation. X509_get0_pubkey_bitstr() extracts the public_key
1751 structure from a certificate. X509_pubkey_digest() digests the public_key
1752 contents: this is used in various key identifiers.
1755 *) Make sk_sort() tolerate a NULL argument.
1756 [Steve Henson reported by Massimiliano Pala <madwolf@comune.modena.it>]
1758 *) New OCSP verify flag OCSP_TRUSTOTHER. When set the "other" certificates
1759 passed by the function are trusted implicitly. If any of them signed the
1760 response then it is assumed to be valid and is not verified.
1763 *) In PKCS7_set_type() initialise content_type in PKCS7_ENC_CONTENT
1764 to data. This was previously part of the PKCS7 ASN1 code. This
1765 was causing problems with OpenSSL created PKCS#12 and PKCS#7 structures.
1766 [Steve Henson, reported by Kenneth R. Robinette
1767 <support@securenetterm.com>]
1769 *) Add CRYPTO_push_info() and CRYPTO_pop_info() calls to new ASN1
1770 routines: without these tracing memory leaks is very painful.
1771 Fix leaks in PKCS12 and PKCS7 routines.
1774 *) Make X509_time_adj() cope with the new behaviour of ASN1_TIME_new().
1775 Previously it initialised the 'type' argument to V_ASN1_UTCTIME which
1776 effectively meant GeneralizedTime would never be used. Now it
1777 is initialised to -1 but X509_time_adj() now has to check the value
1778 and use ASN1_TIME_set() if the value is not V_ASN1_UTCTIME or
1779 V_ASN1_GENERALIZEDTIME, without this it always uses GeneralizedTime.

1783 *) Fixes to BN_to_ASN1_INTEGER when bn is zero. This would previously
1784 result in a zero length in the ASN1_INTEGER structure which was
1785 not consistent with the structure when d2i_ASN1_INTEGER() was used
1786 and would cause ASN1_INTEGER_cmp() to fail. Enhance s2i_ASN1_INTEGER()
1787 to cope with hex and negative integers. Fix bug in i2a_ASN1_INTEGER()
1788 where it did not print out a minus for negative ASN1_INTEGER.
1791 *) Add summary printout to ocsp utility. The various functions which
1792 convert status values to strings have been renamed to:
1793 OCSP_response_status_str(), OCSP_cert_status_str() and
1794 OCSP_crl_reason_str() and are no longer static. New options
1795 to verify nonce values and to disable verification. OCSP response
1796 printout format cleaned up.
1799 *) Add additional OCSP certificate checks. These are those specified
1800 in RFC2560. This consists of two separate checks: the CA of the
1801 certificate being checked must either be the OCSP signer certificate
1802 or the issuer of the OCSP signer certificate. In the latter case the
1803 OCSP signer certificate must contain the OCSP signing extended key
1804 usage. This check is performed by attempting to match the OCSP
1805 signer or the OCSP signer CA to the issuerNameHash and issuerKeyHash
1806 in the OCSP_CERTID structures of the response.
1809 *) Initial OCSP certificate verification added to OCSP_basic_verify()
1810 and related routines. This uses the standard OpenSSL certificate
1811 verify routines to perform initial checks (just CA validity) and
1812 to obtain the certificate chain. Then additional checks will be
1813 performed on the chain. Currently the root CA is checked to see
1814 if it is explicitly trusted for OCSP signing. This is used to set
1815 a root CA as a global signing root: that is any certificate that
1816 chains to that CA is an acceptable OCSP signing certificate.
1819 *) New '-extfile ...' option to 'openssl ca' for reading X.509v3
1820 extensions from a separate configuration file.
1821 As when reading extensions from the main configuration file,
1822 the '-extensions ...' option may be used for specifying the
1824 [Massimiliano Pala <madwolf@comune.modena.it>]
1826 *) New OCSP utility. Allows OCSP requests to be generated or
1827 read. The request can be sent to a responder and the output
1828 parsed, outputed or printed in text form. Not complete yet:
1829 still needs to check the OCSP response validity.
1832 *) New subcommands for 'openssl ca':
1833 'openssl ca -status <serial>' prints the status of the cert with
1834 the given serial number (according to the index file).
1835 'openssl ca -updatedb' updates the expiry status of certificates
1837 [Massimiliano Pala <madwolf@comune.modena.it>]
1839 *) New '-newreq-nodes' command option to CA.pl. This is like
1840 '-newreq', but calls 'openssl req' with the '-nodes' option
1841 so that the resulting key is not encrypted.
1842 [Damien Miller <djm@mindrot.org>]
1844 *) New configuration for the GNU Hurd.
1845 [Jonathan Bartlett <johnnyb@wolfram.com> via Richard Levitte]
1847 *) Initial code to implement OCSP basic response verify. This
1848 is currently incomplete. Currently just finds the signer's
1849 certificate and verifies the signature on the response.
1852 *) New SSLeay_version code SSLEAY_DIR to determine the compiled-in
1853 value of OPENSSLDIR. This is available via the new '-d' option
1854 to 'openssl version', and is also included in 'openssl version -a'.
1857 *) Allowing defining memory allocation callbacks that will be given
1858 file name and line number information in additional arguments
1859 (a const char* and an int). The basic functionality remains, as
1860 well as the original possibility to just replace malloc(),
1861 realloc() and free() by functions that do not know about these
1862 additional arguments. To register and find out the current
1863 settings for extended allocation functions, the following
1864 functions are provided:
1866 CRYPTO_set_mem_ex_functions
1867 CRYPTO_set_locked_mem_ex_functions
1868 CRYPTO_get_mem_ex_functions
1869 CRYPTO_get_locked_mem_ex_functions
1871 These work the same way as CRYPTO_set_mem_functions and friends.
1872 CRYPTO_get_[locked_]mem_functions now writes 0 where such an
1873 extended allocation function is enabled.
1874 Similarly, CRYPTO_get_[locked_]mem_ex_functions writes 0 where
1875 a conventional allocation function is enabled.
1876 [Richard Levitte, Bodo Moeller]
1878 *) Finish off removing the remaining LHASH function pointer casts.
1879 There should no longer be any prototype-casting required when using
1880 the LHASH abstraction, and any casts that remain are "bugs". See
1881 the callback types and macros at the head of lhash.h for details
1882 (and "OBJ_cleanup" in crypto/objects/obj_dat.c as an example).
1885 *) Add automatic query of EGD sockets in RAND_poll() for the unix variant.
1886 If /dev/[u]random devices are not available or do not return enough
1887 entropy, EGD style sockets (served by EGD or PRNGD) will automatically
1889 The locations /var/run/egd-pool, /dev/egd-pool, /etc/egd-pool, and
1890 /etc/entropy will be queried once each in this sequence, quering stops
1891 when enough entropy was collected without querying more sockets.
1894 *) Change the Unix RAND_poll() variant to be able to poll several
1895 random devices, as specified by DEVRANDOM, until a sufficient amount
1896 of data has been collected. We spend at most 10 ms on each file
1897 (select timeout) and read in non-blocking mode. DEVRANDOM now
1898 defaults to the list "/dev/urandom", "/dev/random", "/dev/srandom"
1899 (previously it was just the string "/dev/urandom"), so on typical
1900 platforms the 10 ms delay will never occur.
1901 Also separate out the Unix variant to its own file, rand_unix.c.
1902 For VMS, there's a currently-empty rand_vms.c.
1905 *) Move OCSP client related routines to ocsp_cl.c. These
1906 provide utility functions which an application needing
1907 to issue a request to an OCSP responder and analyse the
1908 response will typically need: as opposed to those which an
1909 OCSP responder itself would need which will be added later.
1911 OCSP_request_sign() signs an OCSP request with an API similar
1912 to PKCS7_sign(). OCSP_response_status() returns status of OCSP
1913 response. OCSP_response_get1_basic() extracts basic response
1914 from response. OCSP_resp_find_status(): finds and extracts status
1915 information from an OCSP_CERTID structure (which will be created
1916 when the request structure is built). These are built from lower
1917 level functions which work on OCSP_SINGLERESP structures but
1918 wont normally be used unless the application wishes to examine
1919 extensions in the OCSP response for example.
1921 Replace nonce routines with a pair of functions.
1922 OCSP_request_add1_nonce() adds a nonce value and optionally
1923 generates a random value. OCSP_check_nonce() checks the
1924 validity of the nonce in an OCSP response.
1927 *) Change function OCSP_request_add() to OCSP_request_add0_id().
1928 This doesn't copy the supplied OCSP_CERTID and avoids the
1929 need to free up the newly created id. Change return type
1930 to OCSP_ONEREQ to return the internal OCSP_ONEREQ structure.
1931 This can then be used to add extensions to the request.
1932 Deleted OCSP_request_new(), since most of its functionality
1933 is now in OCSP_REQUEST_new() (and the case insensitive name
1934 clash) apart from the ability to set the request name which
1935 will be added elsewhere.
1938 *) Update OCSP API. Remove obsolete extensions argument from
1939 various functions. Extensions are now handled using the new
1940 OCSP extension code. New simple OCSP HTTP function which
1941 can be used to send requests and parse the response.
1944 *) Fix the PKCS#7 (S/MIME) code to work with new ASN1. Two new
1945 ASN1_ITEM structures help with sign and verify. PKCS7_ATTR_SIGN
1946 uses the special reorder version of SET OF to sort the attributes
1947 and reorder them to match the encoded order. This resolves a long
1948 standing problem: a verify on a PKCS7 structure just after signing
1949 it used to fail because the attribute order did not match the
1950 encoded order. PKCS7_ATTR_VERIFY does not reorder the attributes:
1951 it uses the received order. This is necessary to tolerate some broken
1952 software that does not order SET OF. This is handled by encoding
1953 as a SEQUENCE OF but using implicit tagging (with UNIVERSAL class)
1954 to produce the required SET OF.
1957 *) Have mk1mf.pl generate the macros OPENSSL_BUILD_SHLIBCRYPTO and
1958 OPENSSL_BUILD_SHLIBSSL and use them appropriately in the header
1959 files to get correct declarations of the ASN.1 item variables.
1962 *) Rewrite of PKCS#12 code to use new ASN1 functionality. Replace many
1963 PKCS#12 macros with real functions. Fix two unrelated ASN1 bugs:
1964 asn1_check_tlen() would sometimes attempt to use 'ctx' when it was
1965 NULL and ASN1_TYPE was not dereferenced properly in asn1_ex_c2i().
1966 New ASN1 macro: DECLARE_ASN1_ITEM() which just declares the relevant
1967 ASN1_ITEM and no wrapper functions.
1970 *) New functions or ASN1_item_d2i_fp() and ASN1_item_d2i_bio(). These
1971 replace the old function pointer based I/O routines. Change most of
1972 the *_d2i_bio() and *_d2i_fp() functions to use these.
1975 *) Enhance mkdef.pl to be more accepting about spacing in C preprocessor
1976 lines, recognice more "algorithms" that can be deselected, and make
1977 it complain about algorithm deselection that isn't recognised.
1980 *) New ASN1 functions to handle dup, sign, verify, digest, pack and
1981 unpack operations in terms of ASN1_ITEM. Modify existing wrappers
1982 to use new functions. Add NO_ASN1_OLD which can be set to remove
1983 some old style ASN1 functions: this can be used to determine if old
1984 code will still work when these eventually go away.
1987 *) New extension functions for OCSP structures, these follow the
1988 same conventions as certificates and CRLs.
1991 *) New function X509V3_add1_i2d(). This automatically encodes and
1992 adds an extension. Its behaviour can be customised with various
1993 flags to append, replace or delete. Various wrappers added for
1994 certifcates and CRLs.
1997 *) Fix to avoid calling the underlying ASN1 print routine when
1998 an extension cannot be parsed. Correct a typo in the
1999 OCSP_SERVICELOC extension. Tidy up print OCSP format.
2002 *) Make mkdef.pl parse some of the ASN1 macros and add apropriate
2003 entries for variables.
2006 *) Add functionality to apps/openssl.c for detecting locking
2007 problems: As the program is single-threaded, all we have
2008 to do is register a locking callback using an array for
2009 storing which locks are currently held by the program.
2012 *) Use a lock around the call to CRYPTO_get_ex_new_index() in
2013 SSL_get_ex_data_X509_STORE_idx(), which is used in
2014 ssl_verify_cert_chain() and thus can be called at any time
2015 during TLS/SSL handshakes so that thread-safety is essential.
2016 Unfortunately, the ex_data design is not at all suited
2017 for multi-threaded use, so it probably should be abolished.
2020 *) Added Broadcom "ubsec" ENGINE to OpenSSL.
2021 [Broadcom, tweaked and integrated by Geoff Thorpe]
2023 *) Move common extension printing code to new function
2024 X509V3_print_extensions(). Reorganise OCSP print routines and
2025 implement some needed OCSP ASN1 functions. Add OCSP extensions.
2028 *) New function X509_signature_print() to remove duplication in some
2032 *) Add a special meaning when SET OF and SEQUENCE OF flags are both
2033 set (this was treated exactly the same as SET OF previously). This
2034 is used to reorder the STACK representing the structure to match the
2035 encoding. This will be used to get round a problem where a PKCS7
2036 structure which was signed could not be verified because the STACK
2037 order did not reflect the encoded order.
2040 *) Reimplement the OCSP ASN1 module using the new code.
2043 *) Update the X509V3 code to permit the use of an ASN1_ITEM structure
2044 for its ASN1 operations. The old style function pointers still exist
2045 for now but they will eventually go away.
2048 *) Merge in replacement ASN1 code from the ASN1 branch. This almost
2049 completely replaces the old ASN1 functionality with a table driven
2050 encoder and decoder which interprets an ASN1_ITEM structure describing
2051 the ASN1 module. Compatibility with the existing ASN1 API (i2d,d2i) is
2052 largely maintained. Almost all of the old asn1_mac.h macro based ASN1
2053 has also been converted to the new form.
2056 *) Change BN_mod_exp_recp so that negative moduli are tolerated
2057 (the sign is ignored). Similarly, ignore the sign in BN_MONT_CTX_set
2058 so that BN_mod_exp_mont and BN_mod_exp_mont_word work
2059 for negative moduli.
2062 *) Fix BN_uadd and BN_usub: Always return non-negative results instead
2063 of not touching the result's sign bit.
2066 *) BN_div bugfix: If the result is 0, the sign (res->neg) must not be
2070 *) Changed the LHASH code to use prototypes for callbacks, and created
2071 macros to declare and implement thin (optionally static) functions
2072 that provide type-safety and avoid function pointer casting for the
2073 type-specific callbacks.
2076 *) Added Kerberos Cipher Suites to be used with TLS, as written in
2078 [Veers Staats <staatsvr@asc.hpc.mil>,
2079 Jeffrey Altman <jaltman@columbia.edu>, via Richard Levitte]
2081 *) Reformat the FAQ so the different questions and answers can be divided
2082 in sections depending on the subject.
2085 *) Have the zlib compression code load ZLIB.DLL dynamically under
2089 *) New function BN_mod_sqrt for computing square roots modulo a prime
2090 (using the probabilistic Tonelli-Shanks algorithm unless
2091 p == 3 (mod 4) or p == 5 (mod 8), which are cases that can
2092 be handled deterministically).
2093 [Lenka Fibikova <fibikova@exp-math.uni-essen.de>, Bodo Moeller]
2095 *) Make BN_mod_inverse faster by explicitly handling small quotients
2096 in the Euclid loop. (Speed gain about 20% for small moduli [256 or
2097 512 bits], about 30% for larger ones [1024 or 2048 bits].)
2100 *) New function BN_kronecker.
2103 *) Fix BN_gcd so that it works on negative inputs; the result is
2104 positive unless both parameters are zero.
2105 Previously something reasonably close to an infinite loop was
2106 possible because numbers could be growing instead of shrinking
2107 in the implementation of Euclid's algorithm.
2110 *) Fix BN_is_word() and BN_is_one() macros to take into account the
2111 sign of the number in question.
2113 Fix BN_is_word(a,w) to work correctly for w == 0.
2115 The old BN_is_word(a,w) macro is now called BN_abs_is_word(a,w)
2116 because its test if the absolute value of 'a' equals 'w'.
2117 Note that BN_abs_is_word does *not* handle w == 0 reliably;
2118 it exists mostly for use in the implementations of BN_is_zero(),
2119 BN_is_one(), and BN_is_word().
2122 *) New function BN_swap.
2125 *) Use BN_nnmod instead of BN_mod in crypto/bn/bn_exp.c so that
2126 the exponentiation functions are more likely to produce reasonable
2127 results on negative inputs.
2130 *) Change BN_mod_mul so that the result is always non-negative.
2131 Previously, it could be negative if one of the factors was negative;
2132 I don't think anyone really wanted that behaviour.
2135 *) Move BN_mod_... functions into new file crypto/bn/bn_mod.c
2136 (except for exponentiation, which stays in crypto/bn/bn_exp.c,
2137 and BN_mod_mul_reciprocal, which stays in crypto/bn/bn_recp.c)
2138 and add new functions:
2147 BN_mod_lshift1_quick
2151 These functions always generate non-negative results.
2153 BN_nnmod otherwise is like BN_mod (if BN_mod computes a remainder r
2154 such that |m| < r < 0, BN_nnmod will output rem + |m| instead).
2156 BN_mod_XXX_quick(r, a, [b,] m) generates the same result as
2157 BN_mod_XXX(r, a, [b,] m, ctx), but requires that a [and b]
2158 be reduced modulo m.
2159 [Lenka Fibikova <fibikova@exp-math.uni-essen.de>, Bodo Moeller]
2162 The following entry accidentily appeared in the CHANGES file
2163 distributed with OpenSSL 0.9.7. The modifications described in
2164 it do *not* apply to OpenSSL 0.9.7.
2166 *) Remove a few calls to bn_wexpand() in BN_sqr() (the one in there
2167 was actually never needed) and in BN_mul(). The removal in BN_mul()
2168 required a small change in bn_mul_part_recursive() and the addition
2169 of the functions bn_cmp_part_words(), bn_sub_part_words() and
2170 bn_add_part_words(), which do the same thing as bn_cmp_words(),
2171 bn_sub_words() and bn_add_words() except they take arrays with
2176 *) In 'openssl passwd', verify passwords read from the terminal
2177 unless the '-salt' option is used (which usually means that
2178 verification would just waste user's time since the resulting
2179 hash is going to be compared with some given password hash)
2180 or the new '-noverify' option is used.
2182 This is an incompatible change, but it does not affect
2183 non-interactive use of 'openssl passwd' (passwords on the command
2184 line, '-stdin' option, '-in ...' option) and thus should not
2188 *) Remove all references to RSAref, since there's no more need for it.
2191 *) Make DSO load along a path given through an environment variable
2192 (SHLIB_PATH) with shl_load().
2195 *) Constify the ENGINE code as a result of BIGNUM constification.
2196 Also constify the RSA code and most things related to it. In a
2197 few places, most notable in the depth of the ASN.1 code, ugly
2198 casts back to non-const were required (to be solved at a later
2202 *) Make it so the openssl application has all engines loaded by default.
2205 *) Constify the BIGNUM routines a little more.
2208 *) Add the following functions:
2210 ENGINE_load_cswift()
2212 ENGINE_load_atalla()
2214 ENGINE_load_builtin_engines()
2216 That way, an application can itself choose if external engines that
2217 are built-in in OpenSSL shall ever be used or not. The benefit is
2218 that applications won't have to be linked with libdl or other dso
2219 libraries unless it's really needed.
2221 Changed 'openssl engine' to load all engines on demand.
2222 Changed the engine header files to avoid the duplication of some
2223 declarations (they differed!).
2226 *) 'openssl engine' can now list capabilities.
2229 *) Better error reporting in 'openssl engine'.
2232 *) Never call load_dh_param(NULL) in s_server.
2235 *) Add engine application. It can currently list engines by name and
2236 identity, and test if they are actually available.
2239 *) Improve RPM specification file by forcing symbolic linking and making
2240 sure the installed documentation is also owned by root.root.
2241 [Damien Miller <djm@mindrot.org>]
2243 *) Give the OpenSSL applications more possibilities to make use of
2244 keys (public as well as private) handled by engines.
2247 *) Add OCSP code that comes from CertCo.
2250 *) Add VMS support for the Rijndael code.
2253 *) Added untested support for Nuron crypto accelerator.
2256 *) Add support for external cryptographic devices. This code was
2257 previously distributed separately as the "engine" branch.
2258 [Geoff Thorpe, Richard Levitte]
2260 *) Rework the filename-translation in the DSO code. It is now possible to
2261 have far greater control over how a "name" is turned into a filename
2262 depending on the operating environment and any oddities about the
2263 different shared library filenames on each system.
2266 *) Support threads on FreeBSD-elf in Configure.
2269 *) Fix for SHA1 assembly problem with MASM: it produces
2270 warnings about corrupt line number information when assembling
2271 with debugging information. This is caused by the overlapping
2273 [Bernd Matthes <mainbug@celocom.de>, Steve Henson]
2276 NCONF_get_number() has no error checking at all. As a replacement,
2277 NCONF_get_number_e() is defined (_e for "error checking") and is
2278 promoted strongly. The old NCONF_get_number is kept around for
2279 binary backward compatibility.
2280 Make it possible for methods to load from something other than a BIO,
2281 by providing a function pointer that is given a name instead of a BIO.
2282 For example, this could be used to load configuration data from an
2286 *) Fix for non blocking accept BIOs. Added new I/O special reason
2287 BIO_RR_ACCEPT to cover this case. Previously use of accept BIOs
2288 with non blocking I/O was not possible because no retry code was
2289 implemented. Also added new SSL code SSL_WANT_ACCEPT to cover
2293 *) Added the beginnings of Rijndael support.
2296 *) Fix for bug in DirectoryString mask setting. Add support for
2297 X509_NAME_print_ex() in 'req' and X509_print_ex() function
2298 to allow certificate printing to more controllable, additional
2299 'certopt' option to 'x509' to allow new printing options to be
2303 *) Clean old EAY MD5 hack from e_os.h.
2306 Changes between 0.9.6g and 0.9.6h [5 Dec 2002]
2308 *) New function OPENSSL_cleanse(), which is used to cleanse a section of
2309 memory from it's contents. This is done with a counter that will
2310 place alternating values in each byte. This can be used to solve
2311 two issues: 1) the removal of calls to memset() by highly optimizing
2312 compilers, and 2) cleansing with other values than 0, since those can
2313 be read through on certain media, for example a swap space on disk.
2316 *) Bugfix: client side session caching did not work with external caching,
2317 because the session->cipher setting was not restored when reloading
2318 from the external cache. This problem was masked, when
2319 SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG (part of SSL_OP_ALL) was set.
2320 (Found by Steve Haslam <steve@araqnid.ddts.net>.)
2323 *) Fix client_certificate (ssl/s2_clnt.c): The permissible total
2324 length of the REQUEST-CERTIFICATE message is 18 .. 34, not 17 .. 33.
2325 [Zeev Lieber <zeev-l@yahoo.com>]
2327 *) Undo an undocumented change introduced in 0.9.6e which caused
2328 repeated calls to OpenSSL_add_all_ciphers() and
2329 OpenSSL_add_all_digests() to be ignored, even after calling
2333 *) Change the default configuration reader to deal with last line not
2334 being properly terminated.
2337 *) Change X509_NAME_cmp() so it applies the special rules on handling
2338 DN values that are of type PrintableString, as well as RDNs of type
2339 emailAddress where the value has the type ia5String.
2340 [stefank@valicert.com via Richard Levitte]
2342 *) Add a SSL_SESS_CACHE_NO_INTERNAL_STORE flag to take over half
2343 the job SSL_SESS_CACHE_NO_INTERNAL_LOOKUP was inconsistently
2344 doing, define a new flag (SSL_SESS_CACHE_NO_INTERNAL) to be
2345 the bitwise-OR of the two for use by the majority of applications
2346 wanting this behaviour, and update the docs. The documented
2347 behaviour and actual behaviour were inconsistent and had been
2348 changing anyway, so this is more a bug-fix than a behavioural
2350 [Geoff Thorpe, diagnosed by Nadav Har'El]
2352 *) Don't impose a 16-byte length minimum on session IDs in ssl/s3_clnt.c
2353 (the SSL 3.0 and TLS 1.0 specifications allow any length up to 32 bytes).
2356 *) Fix initialization code race conditions in
2357 SSLv23_method(), SSLv23_client_method(), SSLv23_server_method(),
2358 SSLv2_method(), SSLv2_client_method(), SSLv2_server_method(),
2359 SSLv3_method(), SSLv3_client_method(), SSLv3_server_method(),
2360 TLSv1_method(), TLSv1_client_method(), TLSv1_server_method(),
2361 ssl2_get_cipher_by_char(),
2362 ssl3_get_cipher_by_char().
2363 [Patrick McCormick <patrick@tellme.com>, Bodo Moeller]
2365 *) Reorder cleanup sequence in SSL_CTX_free(): only remove the ex_data after
2366 the cached sessions are flushed, as the remove_cb() might use ex_data
2367 contents. Bug found by Sam Varshavchik <mrsam@courier-mta.com>
2368 (see [openssl.org #212]).
2369 [Geoff Thorpe, Lutz Jaenicke]
2371 *) Fix typo in OBJ_txt2obj which incorrectly passed the content
2372 length, instead of the encoding length to d2i_ASN1_OBJECT.
2375 Changes between 0.9.6f and 0.9.6g [9 Aug 2002]
2377 *) [In 0.9.6g-engine release:]
2378 Fix crypto/engine/vendor_defns/cswift.h for WIN32 (use '_stdcall').
2379 [Lynn Gazis <lgazis@rainbow.com>]
2381 Changes between 0.9.6e and 0.9.6f [8 Aug 2002]
2383 *) Fix ASN1 checks. Check for overflow by comparing with LONG_MAX
2384 and get fix the header length calculation.
2385 [Florian Weimer <Weimer@CERT.Uni-Stuttgart.DE>,
2386 Alon Kantor <alonk@checkpoint.com> (and others),
2389 *) Use proper error handling instead of 'assertions' in buffer
2390 overflow checks added in 0.9.6e. This prevents DoS (the
2391 assertions could call abort()).
2392 [Arne Ansper <arne@ats.cyber.ee>, Bodo Moeller]
2394 Changes between 0.9.6d and 0.9.6e [30 Jul 2002]
2396 *) Add various sanity checks to asn1_get_length() to reject
2397 the ASN1 length bytes if they exceed sizeof(long), will appear
2398 negative or the content length exceeds the length of the
2400 [Steve Henson, Adi Stav <stav@mercury.co.il>, James Yonan <jim@ntlp.com>]
2402 *) Fix cipher selection routines: ciphers without encryption had no flags
2403 for the cipher strength set and where therefore not handled correctly
2404 by the selection routines (PR #130).
2407 *) Fix EVP_dsa_sha macro.
2411 SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS
2412 for disabling the SSL 3.0/TLS 1.0 CBC vulnerability countermeasure
2413 that was added in OpenSSL 0.9.6d.
2415 As the countermeasure turned out to be incompatible with some
2416 broken SSL implementations, the new option is part of SSL_OP_ALL.
2417 SSL_OP_ALL is usually employed when compatibility with weird SSL
2418 implementations is desired (e.g. '-bugs' option to 's_client' and
2419 's_server'), so the new option is automatically set in many
2423 *) Changes in security patch:
2425 Changes marked "(CHATS)" were sponsored by the Defense Advanced
2426 Research Projects Agency (DARPA) and Air Force Research Laboratory,
2427 Air Force Materiel Command, USAF, under agreement number
2430 *) Add various sanity checks to asn1_get_length() to reject
2431 the ASN1 length bytes if they exceed sizeof(long), will appear
2432 negative or the content length exceeds the length of the
2433 supplied buffer. (CAN-2002-0659)
2434 [Steve Henson, Adi Stav <stav@mercury.co.il>, James Yonan <jim@ntlp.com>]
2436 *) Assertions for various potential buffer overflows, not known to
2438 [Ben Laurie (CHATS)]
2440 *) Various temporary buffers to hold ASCII versions of integers were
2441 too small for 64 bit platforms. (CAN-2002-0655)
2442 [Matthew Byng-Maddick <mbm@aldigital.co.uk> and Ben Laurie (CHATS)>
2444 *) Remote buffer overflow in SSL3 protocol - an attacker could
2445 supply an oversized session ID to a client. (CAN-2002-0656)
2446 [Ben Laurie (CHATS)]
2448 *) Remote buffer overflow in SSL2 protocol - an attacker could
2449 supply an oversized client master key. (CAN-2002-0656)
2450 [Ben Laurie (CHATS)]
2452 Changes between 0.9.6c and 0.9.6d [9 May 2002]
2454 *) Fix crypto/asn1/a_sign.c so that 'parameters' is omitted (not
2455 encoded as NULL) with id-dsa-with-sha1.
2456 [Nils Larsch <nla@trustcenter.de>; problem pointed out by Bodo Moeller]
2458 *) Check various X509_...() return values in apps/req.c.
2459 [Nils Larsch <nla@trustcenter.de>]
2461 *) Fix BASE64 decode (EVP_DecodeUpdate) for data with CR/LF ended lines:
2462 an end-of-file condition would erronously be flagged, when the CRLF
2463 was just at the end of a processed block. The bug was discovered when
2464 processing data through a buffering memory BIO handing the data to a
2465 BASE64-decoding BIO. Bug fund and patch submitted by Pavel Tsekov
2466 <ptsekov@syntrex.com> and Nedelcho Stanev.
2469 *) Implement a countermeasure against a vulnerability recently found
2470 in CBC ciphersuites in SSL 3.0/TLS 1.0: Send an empty fragment
2471 before application data chunks to avoid the use of known IVs
2472 with data potentially chosen by the attacker.
2475 *) Fix length checks in ssl3_get_client_hello().
2478 *) TLS/SSL library bugfix: use s->s3->in_read_app_data differently
2479 to prevent ssl3_read_internal() from incorrectly assuming that
2480 ssl3_read_bytes() found application data while handshake
2481 processing was enabled when in fact s->s3->in_read_app_data was
2482 merely automatically cleared during the initial handshake.
2483 [Bodo Moeller; problem pointed out by Arne Ansper <arne@ats.cyber.ee>]
2485 *) Fix object definitions for Private and Enterprise: they were not
2486 recognized in their shortname (=lowercase) representation. Extend
2487 obj_dat.pl to issue an error when using undefined keywords instead
2488 of silently ignoring the problem (Svenning Sorensen
2489 <sss@sss.dnsalias.net>).
2492 *) Fix DH_generate_parameters() so that it works for 'non-standard'
2493 generators, i.e. generators other than 2 and 5. (Previously, the
2494 code did not properly initialise the 'add' and 'rem' values to
2495 BN_generate_prime().)
2497 In the new general case, we do not insist that 'generator' is
2498 actually a primitive root: This requirement is rather pointless;
2499 a generator of the order-q subgroup is just as good, if not
2503 *) Map new X509 verification errors to alerts. Discovered and submitted by
2504 Tom Wu <tom@arcot.com>.
2507 *) Fix ssl3_pending() (ssl/s3_lib.c) to prevent SSL_pending() from
2508 returning non-zero before the data has been completely received
2509 when using non-blocking I/O.
2510 [Bodo Moeller; problem pointed out by John Hughes]
2512 *) Some of the ciphers missed the strength entry (SSL_LOW etc).
2513 [Ben Laurie, Lutz Jaenicke]
2515 *) Fix bug in SSL_clear(): bad sessions were not removed (found by
2516 Yoram Zahavi <YoramZ@gilian.com>).
2519 *) Add information about CygWin 1.3 and on, and preserve proper
2520 configuration for the versions before that.
2521 [Corinna Vinschen <vinschen@redhat.com> and Richard Levitte]
2523 *) Make removal from session cache (SSL_CTX_remove_session()) more robust:
2524 check whether we deal with a copy of a session and do not delete from
2525 the cache in this case. Problem reported by "Izhar Shoshani Levi"
2526 <izhar@checkpoint.com>.
2529 *) Do not store session data into the internal session cache, if it
2530 is never intended to be looked up (SSL_SESS_CACHE_NO_INTERNAL_LOOKUP
2531 flag is set). Proposed by Aslam <aslam@funk.com>.
2534 *) Have ASN1_BIT_STRING_set_bit() really clear a bit when the requested
2538 *) [In 0.9.6d-engine release:]
2539 Fix a crashbug and a logic bug in hwcrhk_load_pubkey().
2540 [Toomas Kiisk <vix@cyber.ee> via Richard Levitte]
2542 *) Add the configuration target linux-s390x.
2543 [Neale Ferguson <Neale.Ferguson@SoftwareAG-USA.com> via Richard Levitte]
2545 *) The earlier bugfix for the SSL3_ST_SW_HELLO_REQ_C case of
2546 ssl3_accept (ssl/s3_srvr.c) incorrectly used a local flag
2547 variable as an indication that a ClientHello message has been
2548 received. As the flag value will be lost between multiple
2549 invocations of ssl3_accept when using non-blocking I/O, the
2550 function may not be aware that a handshake has actually taken
2551 place, thus preventing a new session from being added to the
2554 To avoid this problem, we now set s->new_session to 2 instead of
2555 using a local variable.
2556 [Lutz Jaenicke, Bodo Moeller]
2558 *) Bugfix: Return -1 from ssl3_get_server_done (ssl3/s3_clnt.c)
2559 if the SSL_R_LENGTH_MISMATCH error is detected.
2560 [Geoff Thorpe, Bodo Moeller]
2562 *) New 'shared_ldflag' column in Configure platform table.
2565 *) Fix EVP_CIPHER_mode macro.
2566 ["Dan S. Camper" <dan@bti.net>]
2568 *) Fix ssl3_read_bytes (ssl/s3_pkt.c): To ignore messages of unknown
2569 type, we must throw them away by setting rr->length to 0.
2570 [D P Chang <dpc@qualys.com>]
2572 Changes between 0.9.6b and 0.9.6c [21 dec 2001]
2574 *) Fix BN_rand_range bug pointed out by Dominikus Scherkl
2575 <Dominikus.Scherkl@biodata.com>. (The previous implementation
2576 worked incorrectly for those cases where range = 10..._2 and
2577 3*range is two bits longer than range.)
2580 *) Only add signing time to PKCS7 structures if it is not already
2584 *) Fix crypto/objects/objects.h: "ld-ce" should be "id-ce",
2585 OBJ_ld_ce should be OBJ_id_ce.
2586 Also some ip-pda OIDs in crypto/objects/objects.txt were
2587 incorrect (cf. RFC 3039).
2588 [Matt Cooper, Frederic Giudicelli, Bodo Moeller]
2590 *) Release CRYPTO_LOCK_DYNLOCK when CRYPTO_destroy_dynlockid()
2591 returns early because it has nothing to do.
2592 [Andy Schneider <andy.schneider@bjss.co.uk>]
2594 *) [In 0.9.6c-engine release:]
2595 Fix mutex callback return values in crypto/engine/hw_ncipher.c.
2596 [Andy Schneider <andy.schneider@bjss.co.uk>]
2598 *) [In 0.9.6c-engine release:]
2599 Add support for Cryptographic Appliance's keyserver technology.
2600 (Use engine 'keyclient')
2601 [Cryptographic Appliances and Geoff Thorpe]
2603 *) Add a configuration entry for OS/390 Unix. The C compiler 'c89'
2604 is called via tools/c89.sh because arguments have to be
2605 rearranged (all '-L' options must appear before the first object
2607 [Richard Shapiro <rshapiro@abinitio.com>]
2609 *) [In 0.9.6c-engine release:]
2610 Add support for Broadcom crypto accelerator cards, backported
2612 [Broadcom, Nalin Dahyabhai <nalin@redhat.com>, Mark Cox]
2614 *) [In 0.9.6c-engine release:]
2615 Add support for SureWare crypto accelerator cards from
2616 Baltimore Technologies. (Use engine 'sureware')
2617 [Baltimore Technologies and Mark Cox]
2619 *) [In 0.9.6c-engine release:]
2620 Add support for crypto accelerator cards from Accelerated
2621 Encryption Processing, www.aep.ie. (Use engine 'aep')
2622 [AEP Inc. and Mark Cox]
2624 *) Add a configuration entry for gcc on UnixWare.
2625 [Gary Benson <gbenson@redhat.com>]
2627 *) Change ssl/s2_clnt.c and ssl/s2_srvr.c so that received handshake
2628 messages are stored in a single piece (fixed-length part and
2629 variable-length part combined) and fix various bugs found on the way.
2632 *) Disable caching in BIO_gethostbyname(), directly use gethostbyname()
2633 instead. BIO_gethostbyname() does not know what timeouts are
2634 appropriate, so entries would stay in cache even when they have
2636 [Bodo Moeller; problem pointed out by Rich Salz <rsalz@zolera.com>
2638 *) Change ssl23_get_client_hello (ssl/s23_srvr.c) behaviour when
2639 faced with a pathologically small ClientHello fragment that does
2640 not contain client_version: Instead of aborting with an error,
2641 simply choose the highest available protocol version (i.e.,
2642 TLS 1.0 unless it is disabled). In practice, ClientHello
2643 messages are never sent like this, but this change gives us
2644 strictly correct behaviour at least for TLS.
2647 *) Fix SSL handshake functions and SSL_clear() such that SSL_clear()
2648 never resets s->method to s->ctx->method when called from within
2649 one of the SSL handshake functions.
2650 [Bodo Moeller; problem pointed out by Niko Baric]
2652 *) In ssl3_get_client_hello (ssl/s3_srvr.c), generate a fatal alert
2653 (sent using the client's version number) if client_version is
2654 smaller than the protocol version in use. Also change
2655 ssl23_get_client_hello (ssl/s23_srvr.c) to select TLS 1.0 if
2656 the client demanded SSL 3.0 but only TLS 1.0 is enabled; then
2657 the client will at least see that alert.
2660 *) Fix ssl3_get_message (ssl/s3_both.c) to handle message fragmentation
2664 *) Avoid infinite loop in ssl3_get_message (ssl/s3_both.c) if a
2665 client receives HelloRequest while in a handshake.
2666 [Bodo Moeller; bug noticed by Andy Schneider <andy.schneider@bjss.co.uk>]
2668 *) Bugfix in ssl3_accept (ssl/s3_srvr.c): Case SSL3_ST_SW_HELLO_REQ_C
2669 should end in 'break', not 'goto end' which circuments various
2670 cleanups done in state SSL_ST_OK. But session related stuff
2671 must be disabled for SSL_ST_OK in the case that we just sent a
2674 Also avoid some overhead by not calling ssl_init_wbio_buffer()
2675 before just sending a HelloRequest.
2676 [Bodo Moeller, Eric Rescorla <ekr@rtfm.com>]
2678 *) Fix ssl/s3_enc.c, ssl/t1_enc.c and ssl/s3_pkt.c so that we don't
2679 reveal whether illegal block cipher padding was found or a MAC
2680 verification error occured. (Neither SSLerr() codes nor alerts
2681 are directly visible to potential attackers, but the information
2682 may leak via logfiles.)
2684 Similar changes are not required for the SSL 2.0 implementation
2685 because the number of padding bytes is sent in clear for SSL 2.0,
2686 and the extra bytes are just ignored. However ssl/s2_pkt.c
2687 failed to verify that the purported number of padding bytes is in
2691 *) Add OpenUNIX-8 support including shared libraries
2692 (Boyd Lynn Gerber <gerberb@zenez.com>).
2695 *) Improve RSA_padding_check_PKCS1_OAEP() check again to avoid
2696 'wristwatch attack' using huge encoding parameters (cf.
2697 James H. Manger's CRYPTO 2001 paper). Note that the
2698 RSA_PKCS1_OAEP_PADDING case of RSA_private_decrypt() does not use
2699 encoding parameters and hence was not vulnerable.
2702 *) BN_sqr() bug fix.
2703 [Ulf Möller, reported by Jim Ellis <jim.ellis@cavium.com>]
2705 *) Rabin-Miller test analyses assume uniformly distributed witnesses,
2706 so use BN_pseudo_rand_range() instead of using BN_pseudo_rand()
2707 followed by modular reduction.
2708 [Bodo Moeller; pointed out by Adam Young <AYoung1@NCSUS.JNJ.COM>]
2710 *) Add BN_pseudo_rand_range() with obvious functionality: BN_rand_range()
2711 equivalent based on BN_pseudo_rand() instead of BN_rand().
2714 *) s3_srvr.c: allow sending of large client certificate lists (> 16 kB).
2715 This function was broken, as the check for a new client hello message
2716 to handle SGC did not allow these large messages.
2717 (Tracked down by "Douglas E. Engert" <deengert@anl.gov>.)
2720 *) Add alert descriptions for TLSv1 to SSL_alert_desc_string[_long]().
2723 *) Fix buggy behaviour of BIO_get_num_renegotiates() and BIO_ctrl()
2724 for BIO_C_GET_WRITE_BUF_SIZE ("Stephen Hinton" <shinton@netopia.com>).
2727 *) Rework the configuration and shared library support for Tru64 Unix.
2728 The configuration part makes use of modern compiler features and
2729 still retains old compiler behavior for those that run older versions
2730 of the OS. The shared library support part includes a variant that
2731 uses the RPATH feature, and is available through the special
2732 configuration target "alpha-cc-rpath", which will never be selected
2734 [Tim Mooney <mooney@dogbert.cc.ndsu.NoDak.edu> via Richard Levitte]
2736 *) In ssl3_get_key_exchange (ssl/s3_clnt.c), call ssl3_get_message()
2737 with the same message size as in ssl3_get_certificate_request().
2738 Otherwise, if no ServerKeyExchange message occurs, CertificateRequest
2739 messages might inadvertently be reject as too long.
2740 [Petr Lampa <lampa@fee.vutbr.cz>]
2742 *) Enhanced support for IA-64 Unix platforms (well, Linux and HP-UX).
2745 *) Modified SSL library such that the verify_callback that has been set
2746 specificly for an SSL object with SSL_set_verify() is actually being
2747 used. Before the change, a verify_callback set with this function was
2748 ignored and the verify_callback() set in the SSL_CTX at the time of
2749 the call was used. New function X509_STORE_CTX_set_verify_cb() introduced
2750 to allow the necessary settings.
2753 *) Initialize static variable in crypto/dsa/dsa_lib.c and crypto/dh/dh_lib.c
2754 explicitly to NULL, as at least on Solaris 8 this seems not always to be
2755 done automatically (in contradiction to the requirements of the C
2756 standard). This made problems when used from OpenSSH.
2759 *) In OpenSSL 0.9.6a and 0.9.6b, crypto/dh/dh_key.c ignored
2760 dh->length and always used
2762 BN_rand_range(priv_key, dh->p).
2764 BN_rand_range() is not necessary for Diffie-Hellman, and this
2765 specific range makes Diffie-Hellman unnecessarily inefficient if
2766 dh->length (recommended exponent length) is much smaller than the
2767 length of dh->p. We could use BN_rand_range() if the order of
2768 the subgroup was stored in the DH structure, but we only have
2773 BN_rand(priv_key, l, ...)
2775 where 'l' is dh->length if this is defined, or BN_num_bits(dh->p)-1
2781 RSA_eay_public_encrypt
2782 RSA_eay_private_decrypt
2783 RSA_eay_private_encrypt (signing)
2784 RSA_eay_public_decrypt (signature verification)
2786 (default implementations for RSA_public_encrypt,
2787 RSA_private_decrypt, RSA_private_encrypt, RSA_public_decrypt),
2788 always reject numbers >= n.
2791 *) In crypto/rand/md_rand.c, use a new short-time lock CRYPTO_LOCK_RAND2
2792 to synchronize access to 'locking_thread'. This is necessary on
2793 systems where access to 'locking_thread' (an 'unsigned long'
2794 variable) is not atomic.
2797 *) In crypto/rand/md_rand.c, set 'locking_thread' to current thread's ID
2798 *before* setting the 'crypto_lock_rand' flag. The previous code had
2799 a race condition if 0 is a valid thread ID.
2800 [Travis Vitek <vitek@roguewave.com>]
2802 *) Add support for shared libraries under Irix.
2803 [Albert Chin-A-Young <china@thewrittenword.com>]
2805 *) Add configuration option to build on Linux on both big-endian and
2807 [Ralf Baechle <ralf@uni-koblenz.de>]
2809 *) Add the possibility to create shared libraries on HP-UX.
2812 Changes between 0.9.6a and 0.9.6b [9 Jul 2001]
2814 *) Change ssleay_rand_bytes (crypto/rand/md_rand.c)
2815 to avoid a SSLeay/OpenSSL PRNG weakness pointed out by
2816 Markku-Juhani O. Saarinen <markku-juhani.saarinen@nokia.com>:
2817 PRNG state recovery was possible based on the output of
2818 one PRNG request appropriately sized to gain knowledge on
2819 'md' followed by enough consecutive 1-byte PRNG requests
2820 to traverse all of 'state'.
2822 1. When updating 'md_local' (the current thread's copy of 'md')
2823 during PRNG output generation, hash all of the previous
2824 'md_local' value, not just the half used for PRNG output.
2826 2. Make the number of bytes from 'state' included into the hash
2827 independent from the number of PRNG bytes requested.
2829 The first measure alone would be sufficient to avoid
2830 Markku-Juhani's attack. (Actually it had never occurred
2831 to me that the half of 'md_local' used for chaining was the
2832 half from which PRNG output bytes were taken -- I had always
2833 assumed that the secret half would be used.) The second
2834 measure makes sure that additional data from 'state' is never
2835 mixed into 'md_local' in small portions; this heuristically
2836 further strengthens the PRNG.
2839 *) Fix crypto/bn/asm/mips3.s.
2842 *) When only the key is given to "enc", the IV is undefined. Print out
2843 an error message in this case.
2846 *) Handle special case when X509_NAME is empty in X509 printing routines.
2849 *) In dsa_do_verify (crypto/dsa/dsa_ossl.c), verify that r and s are
2850 positive and less than q.
2853 *) Don't change *pointer in CRYPTO_add_lock() is add_lock_callback is
2854 used: it isn't thread safe and the add_lock_callback should handle
2856 [Paul Rose <Paul.Rose@bridge.com>]
2858 *) Verify that incoming data obeys the block size in
2859 ssl3_enc (ssl/s3_enc.c) and tls1_enc (ssl/t1_enc.c).
2863 [Ulf Möller, Bodo Möller]
2865 *) The countermeasure against Bleichbacher's attack on PKCS #1 v1.5
2866 RSA encryption was accidentally removed in s3_srvr.c in OpenSSL 0.9.5
2867 when fixing the server behaviour for backwards-compatible 'client
2868 hello' messages. (Note that the attack is impractical against
2869 SSL 3.0 and TLS 1.0 anyway because length and version checking
2870 means that the probability of guessing a valid ciphertext is
2871 around 2^-40; see section 5 in Bleichenbacher's CRYPTO '98
2874 Before 0.9.5, the countermeasure (hide the error by generating a
2875 random 'decryption result') did not work properly because
2876 ERR_clear_error() was missing, meaning that SSL_get_error() would
2877 detect the supposedly ignored error.
2879 Both problems are now fixed.
2882 *) In crypto/bio/bf_buff.c, increase DEFAULT_BUFFER_SIZE to 4096
2883 (previously it was 1024).
2886 *) Fix for compatibility mode trust settings: ignore trust settings
2887 unless some valid trust or reject settings are present.
2890 *) Fix for blowfish EVP: its a variable length cipher.
2893 *) Fix various bugs related to DSA S/MIME verification. Handle missing
2894 parameters in DSA public key structures and return an error in the
2895 DSA routines if parameters are absent.
2898 *) In versions up to 0.9.6, RAND_file_name() resorted to file ".rnd"
2899 in the current directory if neither $RANDFILE nor $HOME was set.
2900 RAND_file_name() in 0.9.6a returned NULL in this case. This has
2901 caused some confusion to Windows users who haven't defined $HOME.
2902 Thus RAND_file_name() is changed again: e_os.h can define a
2903 DEFAULT_HOME, which will be used if $HOME is not set.
2904 For Windows, we use "C:"; on other platforms, we still require
2905 environment variables.
2907 *) Move 'if (!initialized) RAND_poll()' into regions protected by
2908 CRYPTO_LOCK_RAND. This is not strictly necessary, but avoids
2909 having multiple threads call RAND_poll() concurrently.
2912 *) In crypto/rand/md_rand.c, replace 'add_do_not_lock' flag by a
2913 combination of a flag and a thread ID variable.
2914 Otherwise while one thread is in ssleay_rand_bytes (which sets the
2915 flag), *other* threads can enter ssleay_add_bytes without obeying
2916 the CRYPTO_LOCK_RAND lock (and may even illegally release the lock
2917 that they do not hold after the first thread unsets add_do_not_lock).
2920 *) Change bctest again: '-x' expressions are not available in all
2924 Changes between 0.9.6 and 0.9.6a [5 Apr 2001]
2926 *) Fix a couple of memory leaks in PKCS7_dataDecode()
2927 [Steve Henson, reported by Heyun Zheng <hzheng@atdsprint.com>]
2929 *) Change Configure and Makefiles to provide EXE_EXT, which will contain
2930 the default extension for executables, if any. Also, make the perl
2931 scripts that use symlink() to test if it really exists and use "cp"
2932 if it doesn't. All this made OpenSSL compilable and installable in
2936 *) Fix for asn1_GetSequence() for indefinite length constructed data.
2937 If SEQUENCE is length is indefinite just set c->slen to the total
2938 amount of data available.
2939 [Steve Henson, reported by shige@FreeBSD.org]
2940 [This change does not apply to 0.9.7.]
2942 *) Change bctest to avoid here-documents inside command substitution
2943 (workaround for FreeBSD /bin/sh bug).
2944 For compatibility with Ultrix, avoid shell functions (introduced
2945 in the bctest version that searches along $PATH).
2948 *) Rename 'des_encrypt' to 'des_encrypt1'. This avoids the clashes
2949 with des_encrypt() defined on some operating systems, like Solaris
2953 *) Check the result of RSA-CRT (see D. Boneh, R. DeMillo, R. Lipton:
2954 On the Importance of Eliminating Errors in Cryptographic
2955 Computations, J. Cryptology 14 (2001) 2, 101-119,
2956 http://theory.stanford.edu/~dabo/papers/faults.ps.gz).
2959 *) MIPS assembler BIGNUM division bug fix.
2962 *) Disabled incorrect Alpha assembler code.
2965 *) Fix PKCS#7 decode routines so they correctly update the length
2966 after reading an EOC for the EXPLICIT tag.
2968 [This change does not apply to 0.9.7.]
2970 *) Fix bug in PKCS#12 key generation routines. This was triggered
2971 if a 3DES key was generated with a 0 initial byte. Include
2972 PKCS12_BROKEN_KEYGEN compilation option to retain the old
2973 (but broken) behaviour.
2976 *) Enhance bctest to search for a working bc along $PATH and print
2978 [Tim Rice <tim@multitalents.net> via Richard Levitte]
2980 *) Fix memory leaks in err.c: free err_data string if necessary;
2981 don't write to the wrong index in ERR_set_error_data.
2984 *) Implement ssl23_peek (analogous to ssl23_read), which previously
2988 *) Replace rdtsc with _emit statements for VC++ version 5.
2989 [Jeremy Cooper <jeremy@baymoo.org>]
2991 *) Make it possible to reuse SSLv2 sessions.
2994 *) In copy_email() check for >= 0 as a return value for
2995 X509_NAME_get_index_by_NID() since 0 is a valid index.
2996 [Steve Henson reported by Massimiliano Pala <madwolf@opensca.org>]
2998 *) Avoid coredump with unsupported or invalid public keys by checking if
2999 X509_get_pubkey() fails in PKCS7_verify(). Fix memory leak when
3000 PKCS7_verify() fails with non detached data.
3003 *) Don't use getenv in library functions when run as setuid/setgid.
3004 New function OPENSSL_issetugid().
3007 *) Avoid false positives in memory leak detection code (crypto/mem_dbg.c)
3008 due to incorrect handling of multi-threading:
3010 1. Fix timing glitch in the MemCheck_off() portion of CRYPTO_mem_ctrl().
3012 2. Fix logical glitch in is_MemCheck_on() aka CRYPTO_is_mem_check_on().
3014 3. Count how many times MemCheck_off() has been called so that
3015 nested use can be treated correctly. This also avoids
3016 inband-signalling in the previous code (which relied on the
3017 assumption that thread ID 0 is impossible).
3020 *) Add "-rand" option also to s_client and s_server.
3023 *) Fix CPU detection on Irix 6.x.
3024 [Kurt Hockenbury <khockenb@stevens-tech.edu> and
3025 "Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
3027 *) Fix X509_NAME bug which produced incorrect encoding if X509_NAME
3030 [This change does not apply to 0.9.7.]
3032 *) Use the cached encoding of an X509_NAME structure rather than
3033 copying it. This is apparently the reason for the libsafe "errors"
3034 but the code is actually correct.
3037 *) Add new function BN_rand_range(), and fix DSA_sign_setup() to prevent
3038 Bleichenbacher's DSA attack.
3039 Extend BN_[pseudo_]rand: As before, top=1 forces the highest two bits
3040 to be set and top=0 forces the highest bit to be set; top=-1 is new
3041 and leaves the highest bit random.
3042 [Ulf Moeller, Bodo Moeller]
3044 *) In the NCONF_...-based implementations for CONF_... queries
3045 (crypto/conf/conf_lib.c), if the input LHASH is NULL, avoid using
3046 a temporary CONF structure with the data component set to NULL
3047 (which gives segmentation faults in lh_retrieve).
3048 Instead, use NULL for the CONF pointer in CONF_get_string and
3049 CONF_get_number (which may use environment variables) and directly
3050 return NULL from CONF_get_section.
3053 *) Fix potential buffer overrun for EBCDIC.
3056 *) Tolerate nonRepudiation as being valid for S/MIME signing and certSign
3057 keyUsage if basicConstraints absent for a CA.
3060 *) Make SMIME_write_PKCS7() write mail header values with a format that
3061 is more generally accepted (no spaces before the semicolon), since
3062 some programs can't parse those values properly otherwise. Also make
3063 sure BIO's that break lines after each write do not create invalid
3067 *) Make the CRL encoding routines work with empty SEQUENCE OF. The
3068 macros previously used would not encode an empty SEQUENCE OF
3069 and break the signature.
3071 [This change does not apply to 0.9.7.]
3073 *) Zero the premaster secret after deriving the master secret in
3077 *) Add some EVP_add_digest_alias registrations (as found in
3078 OpenSSL_add_all_digests()) to SSL_library_init()
3079 aka OpenSSL_add_ssl_algorithms(). This provides improved
3080 compatibility with peers using X.509 certificates
3081 with unconventional AlgorithmIdentifier OIDs.
3084 *) Fix for Irix with NO_ASM.
3085 ["Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
3087 *) ./config script fixes.
3088 [Ulf Moeller, Richard Levitte]
3090 *) Fix 'openssl passwd -1'.
3093 *) Change PKCS12_key_gen_asc() so it can cope with non null
3094 terminated strings whose length is passed in the passlen
3095 parameter, for example from PEM callbacks. This was done
3096 by adding an extra length parameter to asc2uni().
3097 [Steve Henson, reported by <oddissey@samsung.co.kr>]
3099 *) Fix C code generated by 'openssl dsaparam -C': If a BN_bin2bn
3100 call failed, free the DSA structure.
3103 *) Fix to uni2asc() to cope with zero length Unicode strings.
3104 These are present in some PKCS#12 files.
3107 *) Increase s2->wbuf allocation by one byte in ssl2_new (ssl/s2_lib.c).
3108 Otherwise do_ssl_write (ssl/s2_pkt.c) will write beyond buffer limits
3109 when writing a 32767 byte record.
3110 [Bodo Moeller; problem reported by Eric Day <eday@concentric.net>]
3112 *) In RSA_eay_public_{en,ed}crypt and RSA_eay_mod_exp (rsa_eay.c),
3113 obtain lock CRYPTO_LOCK_RSA before setting rsa->_method_mod_{n,p,q}.
3115 (RSA objects have a reference count access to which is protected
3116 by CRYPTO_LOCK_RSA [see rsa_lib.c, s3_srvr.c, ssl_cert.c, ssl_rsa.c],
3117 so they are meant to be shared between threads.)
3118 [Bodo Moeller, Geoff Thorpe; original patch submitted by
3119 "Reddie, Steven" <Steven.Reddie@ca.com>]
3121 *) Fix a deadlock in CRYPTO_mem_leaks().
3124 *) Use better test patterns in bntest.
3127 *) rand_win.c fix for Borland C.
3130 *) BN_rshift bugfix for n == 0.
3133 *) Add a 'bctest' script that checks for some known 'bc' bugs
3134 so that 'make test' does not abort just because 'bc' is broken.
3137 *) Store verify_result within SSL_SESSION also for client side to
3138 avoid potential security hole. (Re-used sessions on the client side
3139 always resulted in verify_result==X509_V_OK, not using the original
3140 result of the server certificate verification.)
3143 *) Fix ssl3_pending: If the record in s->s3->rrec is not of type
3144 SSL3_RT_APPLICATION_DATA, return 0.
3145 Similarly, change ssl2_pending to return 0 if SSL_in_init(s) is true.
3149 Both ssl2_peek and ssl3_peek, which were totally broken in earlier
3150 releases, have been re-implemented by renaming the previous
3151 implementations of ssl2_read and ssl3_read to ssl2_read_internal
3152 and ssl3_read_internal, respectively, and adding 'peek' parameters
3153 to them. The new ssl[23]_{read,peek} functions are calls to
3154 ssl[23]_read_internal with the 'peek' flag set appropriately.
3155 A 'peek' parameter has also been added to ssl3_read_bytes, which
3156 does the actual work for ssl3_read_internal.
3159 *) Initialise "ex_data" member of RSA/DSA/DH structures prior to calling
3160 the method-specific "init()" handler. Also clean up ex_data after
3161 calling the method-specific "finish()" handler. Previously, this was
3162 happening the other way round.
3165 *) Increase BN_CTX_NUM (the number of BIGNUMs in a BN_CTX) to 16.
3166 The previous value, 12, was not always sufficient for BN_mod_exp().
3169 *) Make sure that shared libraries get the internal name engine with
3170 the full version number and not just 0. This should mark the
3171 shared libraries as not backward compatible. Of course, this should
3172 be changed again when we can guarantee backward binary compatibility.
3175 *) Fix typo in get_cert_by_subject() in by_dir.c
3176 [Jean-Marc Desperrier <jean-marc.desperrier@certplus.com>]
3178 *) Rework the system to generate shared libraries:
3180 - Make note of the expected extension for the shared libraries and
3181 if there is a need for symbolic links from for example libcrypto.so.0
3182 to libcrypto.so.0.9.7. There is extended info in Configure for
3185 - Make as few rebuilds of the shared libraries as possible.
3187 - Still avoid linking the OpenSSL programs with the shared libraries.
3189 - When installing, install the shared libraries separately from the
3193 *) Fix SSL_CTX_set_read_ahead macro to actually use its argument.
3195 Copy SSL_CTX's read_ahead flag to SSL object directly in SSL_new
3196 and not in SSL_clear because the latter is also used by the
3197 accept/connect functions; previously, the settings made by
3198 SSL_set_read_ahead would be lost during the handshake.
3199 [Bodo Moeller; problems reported by Anders Gertz <gertz@epact.se>]
3201 *) Correct util/mkdef.pl to be selective about disabled algorithms.
3202 Previously, it would create entries for disableed algorithms no
3206 *) Added several new manual pages for SSL_* function.
3209 Changes between 0.9.5a and 0.9.6 [24 Sep 2000]
3211 *) In ssl23_get_client_hello, generate an error message when faced
3212 with an initial SSL 3.0/TLS record that is too small to contain the
3213 first two bytes of the ClientHello message, i.e. client_version.
3214 (Note that this is a pathologic case that probably has never happened
3215 in real life.) The previous approach was to use the version number
3216 from the record header as a substitute; but our protocol choice
3217 should not depend on that one because it is not authenticated
3218 by the Finished messages.
3221 *) More robust randomness gathering functions for Windows.
3222 [Jeffrey Altman <jaltman@columbia.edu>]
3224 *) For compatibility reasons if the flag X509_V_FLAG_ISSUER_CHECK is
3225 not set then we don't setup the error code for issuer check errors
3226 to avoid possibly overwriting other errors which the callback does
3227 handle. If an application does set the flag then we assume it knows
3228 what it is doing and can handle the new informational codes
3232 *) Fix for a nasty bug in ASN1_TYPE handling. ASN1_TYPE is used for
3233 a general "ANY" type, as such it should be able to decode anything
3234 including tagged types. However it didn't check the class so it would
3235 wrongly interpret tagged types in the same way as their universal
3236 counterpart and unknown types were just rejected. Changed so that the
3237 tagged and unknown types are handled in the same way as a SEQUENCE:
3238 that is the encoding is stored intact. There is also a new type
3239 "V_ASN1_OTHER" which is used when the class is not universal, in this
3240 case we have no idea what the actual type is so we just lump them all
3244 *) On VMS, stdout may very well lead to a file that is written to
3245 in a record-oriented fashion. That means that every write() will
3246 write a separate record, which will be read separately by the
3247 programs trying to read from it. This can be very confusing.
3249 The solution is to put a BIO filter in the way that will buffer
3250 text until a linefeed is reached, and then write everything a
3251 line at a time, so every record written will be an actual line,
3252 not chunks of lines and not (usually doesn't happen, but I've
3253 seen it once) several lines in one record. BIO_f_linebuffer() is
3256 Currently, it's a VMS-only method, because that's where it has
3257 been tested well enough.
3260 *) Remove 'optimized' squaring variant in BN_mod_mul_montgomery,
3261 it can return incorrect results.
3262 (Note: The buggy variant was not enabled in OpenSSL 0.9.5a,
3263 but it was in 0.9.6-beta[12].)
3266 *) Disable the check for content being present when verifying detached
3267 signatures in pk7_smime.c. Some versions of Netscape (wrongly)
3268 include zero length content when signing messages.
3271 *) New BIO_shutdown_wr macro, which invokes the BIO_C_SHUTDOWN_WR
3272 BIO_ctrl (for BIO pairs).
3275 *) Add DSO method for VMS.
3278 *) Bug fix: Montgomery multiplication could produce results with the
3282 *) Add RPM specification openssl.spec and modify it to build three
3283 packages. The default package contains applications, application
3284 documentation and run-time libraries. The devel package contains
3285 include files, static libraries and function documentation. The
3286 doc package contains the contents of the doc directory. The original
3287 openssl.spec was provided by Damien Miller <djm@mindrot.org>.
3290 *) Add a large number of documentation files for many SSL routines.
3291 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
3293 *) Add a configuration entry for Sony News 4.
3294 [NAKAJI Hiroyuki <nakaji@tutrp.tut.ac.jp>]
3296 *) Don't set the two most significant bits to one when generating a
3297 random number < q in the DSA library.
3300 *) New SSL API mode 'SSL_MODE_AUTO_RETRY'. This disables the default
3301 behaviour that SSL_read may result in SSL_ERROR_WANT_READ (even if
3302 the underlying transport is blocking) if a handshake took place.
3303 (The default behaviour is needed by applications such as s_client
3304 and s_server that use select() to determine when to use SSL_read;
3305 but for applications that know in advance when to expect data, it
3306 just makes things more complicated.)
3309 *) Add RAND_egd_bytes(), which gives control over the number of bytes read
3313 *) Add a few more EBCDIC conditionals that make `req' and `x509'
3314 work better on such systems.
3315 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
3317 *) Add two demo programs for PKCS12_parse() and PKCS12_create().
3318 Update PKCS12_parse() so it copies the friendlyName and the
3319 keyid to the certificates aux info.
3322 *) Fix bug in PKCS7_verify() which caused an infinite loop
3323 if there was more than one signature.
3324 [Sven Uszpelkat <su@celocom.de>]
3326 *) Major change in util/mkdef.pl to include extra information
3327 about each symbol, as well as presentig variables as well
3328 as functions. This change means that there's n more need
3329 to rebuild the .num files when some algorithms are excluded.
3332 *) Allow the verify time to be set by an application,
3333 rather than always using the current time.
3336 *) Phase 2 verify code reorganisation. The certificate
3337 verify code now looks up an issuer certificate by a
3338 number of criteria: subject name, authority key id
3339 and key usage. It also verifies self signed certificates
3340 by the same criteria. The main comparison function is
3341 X509_check_issued() which performs these checks.
3343 Lot of changes were necessary in order to support this
3344 without completely rewriting the lookup code.
3346 Authority and subject key identifier are now cached.
3348 The LHASH 'certs' is X509_STORE has now been replaced
3349 by a STACK_OF(X509_OBJECT). This is mainly because an
3350 LHASH can't store or retrieve multiple objects with
3351 the same hash value.
3353 As a result various functions (which were all internal
3354 use only) have changed to handle the new X509_STORE
3355 structure. This will break anything that messed round
3356 with X509_STORE internally.
3358 The functions X509_STORE_add_cert() now checks for an
3359 exact match, rather than just subject name.
3361 The X509_STORE API doesn't directly support the retrieval
3362 of multiple certificates matching a given criteria, however
3363 this can be worked round by performing a lookup first
3364 (which will fill the cache with candidate certificates)
3365 and then examining the cache for matches. This is probably
3366 the best we can do without throwing out X509_LOOKUP
3367 entirely (maybe later...).
3369 The X509_VERIFY_CTX structure has been enhanced considerably.
3371 All certificate lookup operations now go via a get_issuer()
3372 callback. Although this currently uses an X509_STORE it
3373 can be replaced by custom lookups. This is a simple way
3374 to bypass the X509_STORE hackery necessary to make this
3375 work and makes it possible to use more efficient techniques
3376 in future. A very simple version which uses a simple
3377 STACK for its trusted certificate store is also provided
3378 using X509_STORE_CTX_trusted_stack().
3380 The verify_cb() and verify() callbacks now have equivalents
3381 in the X509_STORE_CTX structure.
3383 X509_STORE_CTX also has a 'flags' field which can be used
3384 to customise the verify behaviour.
3387 *) Add new PKCS#7 signing option PKCS7_NOSMIMECAP which
3388 excludes S/MIME capabilities.
3391 *) When a certificate request is read in keep a copy of the
3392 original encoding of the signed data and use it when outputing
3393 again. Signatures then use the original encoding rather than
3394 a decoded, encoded version which may cause problems if the
3395 request is improperly encoded.
3398 *) For consistency with other BIO_puts implementations, call
3399 buffer_write(b, ...) directly in buffer_puts instead of calling
3402 In BIO_puts, increment b->num_write as in BIO_write.
3403 [Peter.Sylvester@EdelWeb.fr]
3405 *) Fix BN_mul_word for the case where the word is 0. (We have to use
3406 BN_zero, we may not return a BIGNUM with an array consisting of
3410 *) Avoid calling abort() from within the library when problems are
3411 detected, except if preprocessor symbols have been defined
3412 (such as REF_CHECK, BN_DEBUG etc.).
3415 *) New openssl application 'rsautl'. This utility can be
3416 used for low level RSA operations. DER public key
3417 BIO/fp routines also added.
3420 *) New Configure entry and patches for compiling on QNX 4.
3421 [Andreas Schneider <andreas@ds3.etech.fh-hamburg.de>]
3423 *) A demo state-machine implementation was sponsored by
3424 Nuron (http://www.nuron.com/) and is now available in
3425 demos/state_machine.
3428 *) New options added to the 'dgst' utility for signature
3429 generation and verification.
3432 *) Unrecognized PKCS#7 content types are now handled via a
3433 catch all ASN1_TYPE structure. This allows unsupported
3434 types to be stored as a "blob" and an application can
3435 encode and decode it manually.
3438 *) Fix various signed/unsigned issues to make a_strex.c
3440 [Oscar Jacobsson <oscar.jacobsson@celocom.com>]
3442 *) ASN1 fixes. i2d_ASN1_OBJECT was not returning the correct
3443 length if passed a buffer. ASN1_INTEGER_to_BN failed
3444 if passed a NULL BN and its argument was negative.
3445 [Steve Henson, pointed out by Sven Heiberg <sven@tartu.cyber.ee>]
3447 *) Modification to PKCS#7 encoding routines to output definite
3448 length encoding. Since currently the whole structures are in
3449 memory there's not real point in using indefinite length
3450 constructed encoding. However if OpenSSL is compiled with
3451 the flag PKCS7_INDEFINITE_ENCODING the old form is used.
3454 *) Added BIO_vprintf() and BIO_vsnprintf().
3457 *) Added more prefixes to parse for in the the strings written
3458 through a logging bio, to cover all the levels that are available
3459 through syslog. The prefixes are now:
3461 PANIC, EMERG, EMR => LOG_EMERG
3462 ALERT, ALR => LOG_ALERT
3463 CRIT, CRI => LOG_CRIT
3464 ERROR, ERR => LOG_ERR
3465 WARNING, WARN, WAR => LOG_WARNING
3466 NOTICE, NOTE, NOT => LOG_NOTICE
3467 INFO, INF => LOG_INFO
3468 DEBUG, DBG => LOG_DEBUG
3470 and as before, if none of those prefixes are present at the
3471 beginning of the string, LOG_ERR is chosen.
3473 On Win32, the LOG_* levels are mapped according to this:
3475 LOG_EMERG, LOG_ALERT, LOG_CRIT, LOG_ERR => EVENTLOG_ERROR_TYPE
3476 LOG_WARNING => EVENTLOG_WARNING_TYPE
3477 LOG_NOTICE, LOG_INFO, LOG_DEBUG => EVENTLOG_INFORMATION_TYPE
3481 *) Made it possible to reconfigure with just the configuration
3482 argument "reconf" or "reconfigure". The command line arguments
3483 are stored in Makefile.ssl in the variable CONFIGURE_ARGS,
3484 and are retrieved from there when reconfiguring.
3488 [Assar Westerlund <assar@sics.se>, Richard Levitte]
3490 *) Add the arguments -CAfile and -CApath to the pkcs12 utility.
3493 *) The obj_dat.pl script was messing up the sorting of object
3494 names. The reason was that it compared the quoted version
3495 of strings as a result "OCSP" > "OCSP Signing" because
3496 " > SPACE. Changed script to store unquoted versions of
3497 names and add quotes on output. It was also omitting some
3498 names from the lookup table if they were given a default
3499 value (that is if SN is missing it is given the same
3500 value as LN and vice versa), these are now added on the
3501 grounds that if an object has a name we should be able to
3502 look it up. Finally added warning output when duplicate
3503 short or long names are found.
3506 *) Changes needed for Tandem NSK.
3507 [Scott Uroff <scott@xypro.com>]
3509 *) Fix SSL 2.0 rollback checking: Due to an off-by-one error in
3510 RSA_padding_check_SSLv23(), special padding was never detected
3511 and thus the SSL 3.0/TLS 1.0 countermeasure against protocol
3512 version rollback attacks was not effective.
3514 In s23_clnt.c, don't use special rollback-attack detection padding
3515 (RSA_SSLV23_PADDING) if SSL 2.0 is the only protocol enabled in the
3516 client; similarly, in s23_srvr.c, don't do the rollback check if
3517 SSL 2.0 is the only protocol enabled in the server.
3520 *) Make it possible to get hexdumps of unprintable data with 'openssl
3521 asn1parse'. By implication, the functions ASN1_parse_dump() and
3522 BIO_dump_indent() are added.
3525 *) New functions ASN1_STRING_print_ex() and X509_NAME_print_ex()
3526 these print out strings and name structures based on various
3527 flags including RFC2253 support and proper handling of
3528 multibyte characters. Added options to the 'x509' utility
3529 to allow the various flags to be set.
3532 *) Various fixes to use ASN1_TIME instead of ASN1_UTCTIME.
3533 Also change the functions X509_cmp_current_time() and
3534 X509_gmtime_adj() work with an ASN1_TIME structure,
3535 this will enable certificates using GeneralizedTime in validity
3536 dates to be checked.
3539 *) Make the NEG_PUBKEY_BUG code (which tolerates invalid
3540 negative public key encodings) on by default,
3541 NO_NEG_PUBKEY_BUG can be set to disable it.
3544 *) New function c2i_ASN1_OBJECT() which acts on ASN1_OBJECT
3545 content octets. An i2c_ASN1_OBJECT is unnecessary because
3546 the encoding can be trivially obtained from the structure.
3549 *) crypto/err.c locking bugfix: Use write locks (CRYPTO_w_[un]lock),
3550 not read locks (CRYPTO_r_[un]lock).
3553 *) A first attempt at creating official support for shared
3554 libraries through configuration. I've kept it so the
3555 default is static libraries only, and the OpenSSL programs
3556 are always statically linked for now, but there are
3557 preparations for dynamic linking in place.
3558 This has been tested on Linux and Tru64.
3561 *) Randomness polling function for Win9x, as described in:
3562 Peter Gutmann, Software Generation of Practically Strong
3566 *) Fix so PRNG is seeded in req if using an already existing
3570 *) New options to smime application. -inform and -outform
3571 allow alternative formats for the S/MIME message including
3572 PEM and DER. The -content option allows the content to be
3573 specified separately. This should allow things like Netscape
3574 form signing output easier to verify.
3577 *) Fix the ASN1 encoding of tags using the 'long form'.
3580 *) New ASN1 functions, i2c_* and c2i_* for INTEGER and BIT
3581 STRING types. These convert content octets to and from the
3582 underlying type. The actual tag and length octets are
3583 already assumed to have been read in and checked. These
3584 are needed because all other string types have virtually
3585 identical handling apart from the tag. By having versions
3586 of the ASN1 functions that just operate on content octets
3587 IMPLICIT tagging can be handled properly. It also allows
3588 the ASN1_ENUMERATED code to be cut down because ASN1_ENUMERATED
3589 and ASN1_INTEGER are identical apart from the tag.
3592 *) Change the handling of OID objects as follows:
3594 - New object identifiers are inserted in objects.txt, following
3595 the syntax given in objects.README.
3596 - objects.pl is used to process obj_mac.num and create a new
3598 - obj_dat.pl is used to create a new obj_dat.h, using the data in
3601 This is currently kind of a hack, and the perl code in objects.pl
3602 isn't very elegant, but it works as I intended. The simplest way
3603 to check that it worked correctly is to look in obj_dat.h and
3604 check the array nid_objs and make sure the objects haven't moved
3605 around (this is important!). Additions are OK, as well as
3606 consistent name changes.
3609 *) Add BSD-style MD5-based passwords to 'openssl passwd' (option '-1').
3612 *) Addition of the command line parameter '-rand file' to 'openssl req'.
3613 The given file adds to whatever has already been seeded into the
3614 random pool through the RANDFILE configuration file option or
3615 environment variable, or the default random state file.
3618 *) mkstack.pl now sorts each macro group into lexical order.
3619 Previously the output order depended on the order the files
3620 appeared in the directory, resulting in needless rewriting
3624 *) Patches to make OpenSSL compile under Win32 again. Mostly
3625 work arounds for the VC++ problem that it treats func() as
3626 func(void). Also stripped out the parts of mkdef.pl that
3627 added extra typesafe functions: these no longer exist.
3630 *) Reorganisation of the stack code. The macros are now all
3631 collected in safestack.h . Each macro is defined in terms of
3632 a "stack macro" of the form SKM_<name>(type, a, b). The
3633 DEBUG_SAFESTACK is now handled in terms of function casts,
3634 this has the advantage of retaining type safety without the
3635 use of additional functions. If DEBUG_SAFESTACK is not defined
3636 then the non typesafe macros are used instead. Also modified the
3637 mkstack.pl script to handle the new form. Needs testing to see
3638 if which (if any) compilers it chokes and maybe make DEBUG_SAFESTACK
3639 the default if no major problems. Similar behaviour for ASN1_SET_OF
3640 and PKCS12_STACK_OF.
3643 *) When some versions of IIS use the 'NET' form of private key the
3644 key derivation algorithm is different. Normally MD5(password) is
3645 used as a 128 bit RC4 key. In the modified case
3646 MD5(MD5(password) + "SGCKEYSALT") is used insted. Added some
3647 new functions i2d_RSA_NET(), d2i_RSA_NET() etc which are the same
3648 as the old Netscape_RSA functions except they have an additional
3649 'sgckey' parameter which uses the modified algorithm. Also added
3650 an -sgckey command line option to the rsa utility. Thanks to
3651 Adrian Peck <bertie@ncipher.com> for posting details of the modified
3652 algorithm to openssl-dev.
3655 *) The evp_local.h macros were using 'c.##kname' which resulted in
3656 invalid expansion on some systems (SCO 5.0.5 for example).
3657 Corrected to 'c.kname'.
3658 [Phillip Porch <root@theporch.com>]
3660 *) New X509_get1_email() and X509_REQ_get1_email() functions that return
3661 a STACK of email addresses from a certificate or request, these look
3662 in the subject name and the subject alternative name extensions and
3663 omit any duplicate addresses.
3666 *) Re-implement BN_mod_exp2_mont using independent (and larger) windows.
3667 This makes DSA verification about 2 % faster.
3670 *) Increase maximum window size in BN_mod_exp_... to 6 bits instead of 5
3671 (meaning that now 2^5 values will be precomputed, which is only 4 KB
3672 plus overhead for 1024 bit moduli).
3673 This makes exponentiations about 0.5 % faster for 1024 bit
3674 exponents (as measured by "openssl speed rsa2048").
3677 *) Rename memory handling macros to avoid conflicts with other
3679 Malloc => OPENSSL_malloc
3680 Malloc_locked => OPENSSL_malloc_locked
3681 Realloc => OPENSSL_realloc
3682 Free => OPENSSL_free
3685 *) New function BN_mod_exp_mont_word for small bases (roughly 15%
3686 faster than BN_mod_exp_mont, i.e. 7% for a full DH exchange).
3689 *) CygWin32 support.
3690 [John Jarvie <jjarvie@newsguy.com>]
3692 *) The type-safe stack code has been rejigged. It is now only compiled
3693 in when OpenSSL is configured with the DEBUG_SAFESTACK option and
3694 by default all type-specific stack functions are "#define"d back to
3695 standard stack functions. This results in more streamlined output
3696 but retains the type-safety checking possibilities of the original
3700 *) The STACK code has been cleaned up, and certain type declarations
3701 that didn't make a lot of sense have been brought in line. This has
3702 also involved a cleanup of sorts in safestack.h to more correctly
3703 map type-safe stack functions onto their plain stack counterparts.
3704 This work has also resulted in a variety of "const"ifications of
3705 lots of the code, especially "_cmp" operations which should normally
3706 be prototyped with "const" parameters anyway.
3709 *) When generating bytes for the first time in md_rand.c, 'stir the pool'
3710 by seeding with STATE_SIZE dummy bytes (with zero entropy count).
3711 (The PRNG state consists of two parts, the large pool 'state' and 'md',
3712 where all of 'md' is used each time the PRNG is used, but 'state'
3713 is used only indexed by a cyclic counter. As entropy may not be
3714 well distributed from the beginning, 'md' is important as a
3715 chaining variable. However, the output function chains only half
3716 of 'md', i.e. 80 bits. ssleay_rand_add, on the other hand, chains
3717 all of 'md', and seeding with STATE_SIZE dummy bytes will result
3718 in all of 'state' being rewritten, with the new values depending
3719 on virtually all of 'md'. This overcomes the 80 bit limitation.)
3722 *) In ssl/s2_clnt.c and ssl/s3_clnt.c, call ERR_clear_error() when
3723 the handshake is continued after ssl_verify_cert_chain();
3724 otherwise, if SSL_VERIFY_NONE is set, remaining error codes
3725 can lead to 'unexplainable' connection aborts later.
3726 [Bodo Moeller; problem tracked down by Lutz Jaenicke]
3728 *) Major EVP API cipher revision.
3729 Add hooks for extra EVP features. This allows various cipher
3730 parameters to be set in the EVP interface. Support added for variable
3731 key length ciphers via the EVP_CIPHER_CTX_set_key_length() function and
3732 setting of RC2 and RC5 parameters.
3734 Modify EVP_OpenInit() and EVP_SealInit() to cope with variable key length
3737 Remove lots of duplicated code from the EVP library. For example *every*
3738 cipher init() function handles the 'iv' in the same way according to the
3739 cipher mode. They also all do nothing if the 'key' parameter is NULL and
3740 for CFB and OFB modes they zero ctx->num.
3742 New functionality allows removal of S/MIME code RC2 hack.
3744 Most of the routines have the same form and so can be declared in terms
3747 By shifting this to the top level EVP_CipherInit() it can be removed from
3748 all individual ciphers. If the cipher wants to handle IVs or keys
3749 differently it can set the EVP_CIPH_CUSTOM_IV or EVP_CIPH_ALWAYS_CALL_INIT
3752 Change lots of functions like EVP_EncryptUpdate() to now return a
3753 value: although software versions of the algorithms cannot fail
3754 any installed hardware versions can.
3757 *) Implement SSL_OP_TLS_ROLLBACK_BUG: In ssl3_get_client_key_exchange, if
3758 this option is set, tolerate broken clients that send the negotiated
3759 protocol version number instead of the requested protocol version
3763 *) Call dh_tmp_cb (set by ..._TMP_DH_CB) with correct 'is_export' flag;
3764 i.e. non-zero for export ciphersuites, zero otherwise.
3765 Previous versions had this flag inverted, inconsistent with
3766 rsa_tmp_cb (..._TMP_RSA_CB).
3767 [Bodo Moeller; problem reported by Amit Chopra]
3769 *) Add missing DSA library text string. Work around for some IIS
3770 key files with invalid SEQUENCE encoding.
3773 *) Add a document (doc/standards.txt) that list all kinds of standards
3774 and so on that are implemented in OpenSSL.
3777 *) Enhance c_rehash script. Old version would mishandle certificates
3778 with the same subject name hash and wouldn't handle CRLs at all.
3779 Added -fingerprint option to crl utility, to support new c_rehash
3783 *) Eliminate non-ANSI declarations in crypto.h and stack.h.
3786 *) Fix for SSL server purpose checking. Server checking was
3787 rejecting certificates which had extended key usage present
3788 but no ssl client purpose.
3789 [Steve Henson, reported by Rene Grosser <grosser@hisolutions.com>]
3791 *) Make PKCS#12 code work with no password. The PKCS#12 spec
3792 is a little unclear about how a blank password is handled.
3793 Since the password in encoded as a BMPString with terminating
3794 double NULL a zero length password would end up as just the
3795 double NULL. However no password at all is different and is
3796 handled differently in the PKCS#12 key generation code. NS
3797 treats a blank password as zero length. MSIE treats it as no
3798 password on export: but it will try both on import. We now do
3799 the same: PKCS12_parse() tries zero length and no password if
3800 the password is set to "" or NULL (NULL is now a valid password:
3801 it wasn't before) as does the pkcs12 application.
3804 *) Bugfixes in apps/x509.c: Avoid a memory leak; and don't use
3805 perror when PEM_read_bio_X509_REQ fails, the error message must
3806 be obtained from the error queue.
3809 *) Avoid 'thread_hash' memory leak in crypto/err/err.c by freeing
3810 it in ERR_remove_state if appropriate, and change ERR_get_state
3811 accordingly to avoid race conditions (this is necessary because
3812 thread_hash is no longer constant once set).
3815 *) Bugfix for linux-elf makefile.one.
3818 *) RSA_get_default_method() will now cause a default
3819 RSA_METHOD to be chosen if one doesn't exist already.
3820 Previously this was only set during a call to RSA_new()
3821 or RSA_new_method(NULL) meaning it was possible for
3822 RSA_get_default_method() to return NULL.
3825 *) Added native name translation to the existing DSO code
3826 that will convert (if the flag to do so is set) filenames
3827 that are sufficiently small and have no path information
3828 into a canonical native form. Eg. "blah" converted to
3829 "libblah.so" or "blah.dll" etc.
3832 *) New function ERR_error_string_n(e, buf, len) which is like
3833 ERR_error_string(e, buf), but writes at most 'len' bytes
3834 including the 0 terminator. For ERR_error_string_n, 'buf'
3836 [Damien Miller <djm@mindrot.org>, Bodo Moeller]
3838 *) CONF library reworked to become more general. A new CONF
3839 configuration file reader "class" is implemented as well as a
3840 new functions (NCONF_*, for "New CONF") to handle it. The now
3841 old CONF_* functions are still there, but are reimplemented to
3842 work in terms of the new functions. Also, a set of functions
3843 to handle the internal storage of the configuration data is
3844 provided to make it easier to write new configuration file
3845 reader "classes" (I can definitely see something reading a
3846 configuration file in XML format, for example), called _CONF_*,
3847 or "the configuration storage API"...
3849 The new configuration file reading functions are:
3851 NCONF_new, NCONF_free, NCONF_load, NCONF_load_fp, NCONF_load_bio,
3852 NCONF_get_section, NCONF_get_string, NCONF_get_numbre
3854 NCONF_default, NCONF_WIN32
3856 NCONF_dump_fp, NCONF_dump_bio
3858 NCONF_default and NCONF_WIN32 are method (or "class") choosers,
3859 NCONF_new creates a new CONF object. This works in the same way
3860 as other interfaces in OpenSSL, like the BIO interface.
3861 NCONF_dump_* dump the internal storage of the configuration file,
3862 which is useful for debugging. All other functions take the same
3863 arguments as the old CONF_* functions wth the exception of the
3864 first that must be a `CONF *' instead of a `LHASH *'.
3866 To make it easer to use the new classes with the old CONF_* functions,
3867 the function CONF_set_default_method is provided.
3870 *) Add '-tls1' option to 'openssl ciphers', which was already
3871 mentioned in the documentation but had not been implemented.
3872 (This option is not yet really useful because even the additional
3873 experimental TLS 1.0 ciphers are currently treated as SSL 3.0 ciphers.)
3876 *) Initial DSO code added into libcrypto for letting OpenSSL (and
3877 OpenSSL-based applications) load shared libraries and bind to
3878 them in a portable way.
3879 [Geoff Thorpe, with contributions from Richard Levitte]
3881 Changes between 0.9.5 and 0.9.5a [1 Apr 2000]
3883 *) Make sure _lrotl and _lrotr are only used with MSVC.
3885 *) Use lock CRYPTO_LOCK_RAND correctly in ssleay_rand_status
3886 (the default implementation of RAND_status).
3888 *) Rename openssl x509 option '-crlext', which was added in 0.9.5,
3889 to '-clrext' (= clear extensions), as intended and documented.
3890 [Bodo Moeller; inconsistency pointed out by Michael Attili
3893 *) Fix for HMAC. It wasn't zeroing the rest of the block if the key length
3894 was larger than the MD block size.
3895 [Steve Henson, pointed out by Yost William <YostW@tce.com>]
3897 *) Modernise PKCS12_parse() so it uses STACK_OF(X509) for its ca argument
3898 fix a leak when the ca argument was passed as NULL. Stop X509_PUBKEY_set()
3899 using the passed key: if the passed key was a private key the result
3900 of X509_print(), for example, would be to print out all the private key
3904 *) des_quad_cksum() byte order bug fix.
3905 [Ulf Möller, using the problem description in krb4-0.9.7, where
3906 the solution is attributed to Derrick J Brashear <shadow@DEMENTIA.ORG>]
3908 *) Fix so V_ASN1_APP_CHOOSE works again: however its use is strongly
3910 [Steve Henson, pointed out by Brian Korver <briank@cs.stanford.edu>]
3912 *) For easily testing in shell scripts whether some command
3913 'openssl XXX' exists, the new pseudo-command 'openssl no-XXX'
3914 returns with exit code 0 iff no command of the given name is available.
3915 'no-XXX' is printed in this case, 'XXX' otherwise. In both cases,
3916 the output goes to stdout and nothing is printed to stderr.
3917 Additional arguments are always ignored.
3919 Since for each cipher there is a command of the same name,
3920 the 'no-cipher' compilation switches can be tested this way.
3922 ('openssl no-XXX' is not able to detect pseudo-commands such
3923 as 'quit', 'list-XXX-commands', or 'no-XXX' itself.)
3926 *) Update test suite so that 'make test' succeeds in 'no-rsa' configuration.
3929 *) For SSL_[CTX_]set_tmp_dh, don't create a DH key if SSL_OP_SINGLE_DH_USE
3930 is set; it will be thrown away anyway because each handshake creates
3932 ssl_cert_dup, which is used by SSL_new, now copies DH keys in addition
3933 to parameters -- in previous versions (since OpenSSL 0.9.3) the
3934 'default key' from SSL_CTX_set_tmp_dh would always be lost, meanining
3935 you effectivly got SSL_OP_SINGLE_DH_USE when using this macro.
3938 *) New s_client option -ign_eof: EOF at stdin is ignored, and
3939 'Q' and 'R' lose their special meanings (quit/renegotiate).
3940 This is part of what -quiet does; unlike -quiet, -ign_eof
3941 does not suppress any output.
3944 *) Add compatibility options to the purpose and trust code. The
3945 purpose X509_PURPOSE_ANY is "any purpose" which automatically
3946 accepts a certificate or CA, this was the previous behaviour,
3947 with all the associated security issues.
3949 X509_TRUST_COMPAT is the old trust behaviour: only and
3950 automatically trust self signed roots in certificate store. A
3951 new trust setting X509_TRUST_DEFAULT is used to specify that
3952 a purpose has no associated trust setting and it should instead
3953 use the value in the default purpose.
3956 *) Fix the PKCS#8 DSA private key code so it decodes keys again
3957 and fix a memory leak.
3960 *) In util/mkerr.pl (which implements 'make errors'), preserve
3961 reason strings from the previous version of the .c file, as
3962 the default to have only downcase letters (and digits) in
3963 automatically generated reasons codes is not always appropriate.
3966 *) In ERR_load_ERR_strings(), build an ERR_LIB_SYS error reason table
3967 using strerror. Previously, ERR_reason_error_string() returned
3968 library names as reason strings for SYSerr; but SYSerr is a special
3969 case where small numbers are errno values, not library numbers.
3972 *) Add '-dsaparam' option to 'openssl dhparam' application. This
3973 converts DSA parameters into DH parameters. (When creating parameters,
3974 DSA_generate_parameters is used.)
3977 *) Include 'length' (recommended exponent length) in C code generated
3978 by 'openssl dhparam -C'.
3981 *) The second argument to set_label in perlasm was already being used
3982 so couldn't be used as a "file scope" flag. Moved to third argument
3986 *) In PEM_ASN1_write_bio and some other functions, use RAND_pseudo_bytes
3987 instead of RAND_bytes for encryption IVs and salts.
3990 *) Include RAND_status() into RAND_METHOD instead of implementing
3991 it only for md_rand.c Otherwise replacing the PRNG by calling
3992 RAND_set_rand_method would be impossible.
3995 *) Don't let DSA_generate_key() enter an infinite loop if the random
3996 number generation fails.
3999 *) New 'rand' application for creating pseudo-random output.
4002 *) Added configuration support for Linux/IA64
4003 [Rolf Haberrecker <rolf@suse.de>]
4005 *) Assembler module support for Mingw32.
4008 *) Shared library support for HPUX (in shlib/).
4009 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE> and Anonymous]
4011 *) Shared library support for Solaris gcc.
4012 [Lutz Behnke <behnke@trustcenter.de>]
4014 Changes between 0.9.4 and 0.9.5 [28 Feb 2000]
4016 *) PKCS7_encrypt() was adding text MIME headers twice because they
4017 were added manually and by SMIME_crlf_copy().
4020 *) In bntest.c don't call BN_rand with zero bits argument.
4021 [Steve Henson, pointed out by Andrew W. Gray <agray@iconsinc.com>]
4023 *) BN_mul bugfix: In bn_mul_part_recursion() only the a>a[n] && b>b[n]
4024 case was implemented. This caused BN_div_recp() to fail occasionally.
4027 *) Add an optional second argument to the set_label() in the perl
4028 assembly language builder. If this argument exists and is set
4029 to 1 it signals that the assembler should use a symbol whose
4030 scope is the entire file, not just the current function. This
4031 is needed with MASM which uses the format label:: for this scope.
4032 [Steve Henson, pointed out by Peter Runestig <peter@runestig.com>]
4034 *) Change the ASN1 types so they are typedefs by default. Before
4035 almost all types were #define'd to ASN1_STRING which was causing
4036 STACK_OF() problems: you couldn't declare STACK_OF(ASN1_UTF8STRING)
4040 *) Change names of new functions to the new get1/get0 naming
4041 convention: After 'get1', the caller owns a reference count
4042 and has to call ..._free; 'get0' returns a pointer to some
4043 data structure without incrementing reference counters.
4044 (Some of the existing 'get' functions increment a reference
4045 counter, some don't.)
4046 Similarly, 'set1' and 'add1' functions increase reference
4047 counters or duplicate objects.
4050 *) Allow for the possibility of temp RSA key generation failure:
4051 the code used to assume it always worked and crashed on failure.
4054 *) Fix potential buffer overrun problem in BIO_printf().
4055 [Ulf Möller, using public domain code by Patrick Powell; problem
4056 pointed out by David Sacerdote <das33@cornell.edu>]
4058 *) Support EGD <http://www.lothar.com/tech/crypto/>. New functions
4059 RAND_egd() and RAND_status(). In the command line application,
4060 the EGD socket can be specified like a seed file using RANDFILE
4064 *) Allow the string CERTIFICATE to be tolerated in PKCS#7 structures.
4065 Some CAs (e.g. Verisign) distribute certificates in this form.
4068 *) Remove the SSL_ALLOW_ADH compile option and set the default cipher
4069 list to exclude them. This means that no special compilation option
4070 is needed to use anonymous DH: it just needs to be included in the
4074 *) Change the EVP_MD_CTX_type macro so its meaning consistent with
4075 EVP_MD_type. The old functionality is available in a new macro called
4076 EVP_MD_md(). Change code that uses it and update docs.
4079 *) ..._ctrl functions now have corresponding ..._callback_ctrl functions
4080 where the 'void *' argument is replaced by a function pointer argument.
4081 Previously 'void *' was abused to point to functions, which works on
4082 many platforms, but is not correct. As these functions are usually
4083 called by macros defined in OpenSSL header files, most source code
4084 should work without changes.
4087 *) <openssl/opensslconf.h> (which is created by Configure) now contains
4088 sections with information on -D... compiler switches used for
4089 compiling the library so that applications can see them. To enable
4090 one of these sections, a pre-processor symbol OPENSSL_..._DEFINES
4091 must be defined. E.g.,
4092 #define OPENSSL_ALGORITHM_DEFINES
4093 #include <openssl/opensslconf.h>
4094 defines all pertinent NO_<algo> symbols, such as NO_IDEA, NO_RSA, etc.
4095 [Richard Levitte, Ulf and Bodo Möller]
4097 *) Bugfix: Tolerate fragmentation and interleaving in the SSL 3/TLS
4101 *) Change the 'other' type in certificate aux info to a STACK_OF
4102 X509_ALGOR. Although not an AlgorithmIdentifier as such it has
4103 the required ASN1 format: arbitrary types determined by an OID.
4106 *) Add some PEM_write_X509_REQ_NEW() functions and a command line
4107 argument to 'req'. This is not because the function is newer or
4108 better than others it just uses the work 'NEW' in the certificate
4109 request header lines. Some software needs this.
4112 *) Reorganise password command line arguments: now passwords can be
4113 obtained from various sources. Delete the PEM_cb function and make
4114 it the default behaviour: i.e. if the callback is NULL and the
4115 usrdata argument is not NULL interpret it as a null terminated pass
4116 phrase. If usrdata and the callback are NULL then the pass phrase
4117 is prompted for as usual.
4120 *) Add support for the Compaq Atalla crypto accelerator. If it is installed,
4121 the support is automatically enabled. The resulting binaries will
4122 autodetect the card and use it if present.
4123 [Ben Laurie and Compaq Inc.]
4125 *) Work around for Netscape hang bug. This sends certificate request
4126 and server done in one record. Since this is perfectly legal in the
4127 SSL/TLS protocol it isn't a "bug" option and is on by default. See
4128 the bugs/SSLv3 entry for more info.
4131 *) HP-UX tune-up: new unified configs, HP C compiler bug workaround.
4134 *) Add -rand argument to smime and pkcs12 applications and read/write
4138 *) New 'passwd' tool for crypt(3) and apr1 password hashes.
4141 *) Add command line password options to the remaining applications.
4144 *) Bug fix for BN_div_recp() for numerators with an even number of
4148 *) More tests in bntest.c, and changed test_bn output.
4151 *) ./config recognizes MacOS X now.
4154 *) Bug fix for BN_div() when the first words of num and divsor are
4155 equal (it gave wrong results if (rem=(n1-q*d0)&BN_MASK2) < d0).
4158 *) Add support for various broken PKCS#8 formats, and command line
4159 options to produce them.
4162 *) New functions BN_CTX_start(), BN_CTX_get() and BT_CTX_end() to
4163 get temporary BIGNUMs from a BN_CTX.
4166 *) Correct return values in BN_mod_exp_mont() and BN_mod_exp2_mont()
4170 *) Change the SSLeay_add_all_*() functions to OpenSSL_add_all_*() and
4171 include a #define from the old name to the new. The original intent
4172 was that statically linked binaries could for example just call
4173 SSLeay_add_all_ciphers() to just add ciphers to the table and not
4174 link with digests. This never worked becayse SSLeay_add_all_digests()
4175 and SSLeay_add_all_ciphers() were in the same source file so calling
4176 one would link with the other. They are now in separate source files.
4179 *) Add a new -notext option to 'ca' and a -pubkey option to 'spkac'.
4182 *) Use a less unusual form of the Miller-Rabin primality test (it used
4183 a binary algorithm for exponentiation integrated into the Miller-Rabin
4184 loop, our standard modexp algorithms are faster).
4187 *) Support for the EBCDIC character set completed.
4188 [Martin Kraemer <Martin.Kraemer@Mch.SNI.De>]
4190 *) Source code cleanups: use const where appropriate, eliminate casts,
4191 use void * instead of char * in lhash.
4194 *) Bugfix: ssl3_send_server_key_exchange was not restartable
4195 (the state was not changed to SSL3_ST_SW_KEY_EXCH_B, and because of
4196 this the server could overwrite ephemeral keys that the client
4200 *) Turn DSA_is_prime into a macro that calls BN_is_prime,
4201 using 50 iterations of the Rabin-Miller test.
4203 DSA_generate_parameters now uses BN_is_prime_fasttest (with 50
4204 iterations of the Rabin-Miller test as required by the appendix
4205 to FIPS PUB 186[-1]) instead of DSA_is_prime.
4206 As BN_is_prime_fasttest includes trial division, DSA parameter
4207 generation becomes much faster.
4209 This implies a change for the callback functions in DSA_is_prime
4210 and DSA_generate_parameters: The callback function is called once
4211 for each positive witness in the Rabin-Miller test, not just
4212 occasionally in the inner loop; and the parameters to the
4213 callback function now provide an iteration count for the outer
4214 loop rather than for the current invocation of the inner loop.
4215 DSA_generate_parameters additionally can call the callback
4216 function with an 'iteration count' of -1, meaning that a
4217 candidate has passed the trial division test (when q is generated
4218 from an application-provided seed, trial division is skipped).
4221 *) New function BN_is_prime_fasttest that optionally does trial
4222 division before starting the Rabin-Miller test and has
4223 an additional BN_CTX * argument (whereas BN_is_prime always
4224 has to allocate at least one BN_CTX).
4225 'callback(1, -1, cb_arg)' is called when a number has passed the
4226 trial division stage.
4229 *) Fix for bug in CRL encoding. The validity dates weren't being handled
4233 *) New -pkcs12 option to CA.pl script to write out a PKCS#12 file.
4236 *) New function BN_pseudo_rand().
4239 *) Clean up BN_mod_mul_montgomery(): replace the broken (and unreadable)
4240 bignum version of BN_from_montgomery() with the working code from
4241 SSLeay 0.9.0 (the word based version is faster anyway), and clean up
4245 *) Avoid a race condition in s2_clnt.c (function get_server_hello) that
4246 made it impossible to use the same SSL_SESSION data structure in
4247 SSL2 clients in multiple threads.
4250 *) The return value of RAND_load_file() no longer counts bytes obtained
4251 by stat(). RAND_load_file(..., -1) is new and uses the complete file
4252 to seed the PRNG (previously an explicit byte count was required).
4253 [Ulf Möller, Bodo Möller]
4255 *) Clean up CRYPTO_EX_DATA functions, some of these didn't have prototypes
4256 used (char *) instead of (void *) and had casts all over the place.
4259 *) Make BN_generate_prime() return NULL on error if ret!=NULL.
4262 *) Retain source code compatibility for BN_prime_checks macro:
4263 BN_is_prime(..., BN_prime_checks, ...) now uses
4264 BN_prime_checks_for_size to determine the appropriate number of
4265 Rabin-Miller iterations.
4268 *) Diffie-Hellman uses "safe" primes: DH_check() return code renamed to
4269 DH_CHECK_P_NOT_SAFE_PRIME.
4270 (Check if this is true? OpenPGP calls them "strong".)
4273 *) Merge the functionality of "dh" and "gendh" programs into a new program
4274 "dhparam". The old programs are retained for now but will handle DH keys
4275 (instead of parameters) in future.
4278 *) Make the ciphers, s_server and s_client programs check the return values
4279 when a new cipher list is set.
4282 *) Enhance the SSL/TLS cipher mechanism to correctly handle the TLS 56bit
4283 ciphers. Before when the 56bit ciphers were enabled the sorting was
4286 The syntax for the cipher sorting has been extended to support sorting by
4287 cipher-strength (using the strength_bits hard coded in the tables).
4288 The new command is "@STRENGTH" (see also doc/apps/ciphers.pod).
4290 Fix a bug in the cipher-command parser: when supplying a cipher command
4291 string with an "undefined" symbol (neither command nor alphanumeric
4292 [A-Za-z0-9], ssl_set_cipher_list used to hang in an endless loop. Now
4293 an error is flagged.
4295 Due to the strength-sorting extension, the code of the
4296 ssl_create_cipher_list() function was completely rearranged. I hope that
4297 the readability was also increased :-)
4298 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
4300 *) Minor change to 'x509' utility. The -CAcreateserial option now uses 1
4301 for the first serial number and places 2 in the serial number file. This
4302 avoids problems when the root CA is created with serial number zero and
4303 the first user certificate has the same issuer name and serial number
4307 *) Fixes to X509_ATTRIBUTE utilities, change the 'req' program so it uses
4308 the new code. Add documentation for this stuff.
4311 *) Changes to X509_ATTRIBUTE utilities. These have been renamed from
4312 X509_*() to X509at_*() on the grounds that they don't handle X509
4313 structures and behave in an analagous way to the X509v3 functions:
4314 they shouldn't be called directly but wrapper functions should be used
4317 So we also now have some wrapper functions that call the X509at functions
4318 when passed certificate requests. (TO DO: similar things can be done with
4319 PKCS#7 signed and unsigned attributes, PKCS#12 attributes and a few other
4320 things. Some of these need some d2i or i2d and print functionality
4321 because they handle more complex structures.)
4324 *) Add missing #ifndefs that caused missing symbols when building libssl
4325 as a shared library without RSA. Use #ifndef NO_SSL2 instead of
4326 NO_RSA in ssl/s2*.c.
4327 [Kris Kennaway <kris@hub.freebsd.org>, modified by Ulf Möller]
4329 *) Precautions against using the PRNG uninitialized: RAND_bytes() now
4330 has a return value which indicates the quality of the random data
4331 (1 = ok, 0 = not seeded). Also an error is recorded on the thread's
4332 error queue. New function RAND_pseudo_bytes() generates output that is
4333 guaranteed to be unique but not unpredictable. RAND_add is like
4334 RAND_seed, but takes an extra argument for an entropy estimate
4335 (RAND_seed always assumes full entropy).
4338 *) Do more iterations of Rabin-Miller probable prime test (specifically,
4339 3 for 1024-bit primes, 6 for 512-bit primes, 12 for 256-bit primes
4340 instead of only 2 for all lengths; see BN_prime_checks_for_size definition
4341 in crypto/bn/bn_prime.c for the complete table). This guarantees a
4342 false-positive rate of at most 2^-80 for random input.
4345 *) Rewrite ssl3_read_n (ssl/s3_pkt.c) avoiding a couple of bugs.
4348 *) New function X509_CTX_rget_chain() (renamed to X509_CTX_get1_chain
4349 in the 0.9.5 release), this returns the chain
4350 from an X509_CTX structure with a dup of the stack and all
4351 the X509 reference counts upped: so the stack will exist
4352 after X509_CTX_cleanup() has been called. Modify pkcs12.c
4355 Also make SSL_SESSION_print() print out the verify return
4359 *) Add manpage for the pkcs12 command. Also change the default
4360 behaviour so MAC iteration counts are used unless the new
4361 -nomaciter option is used. This improves file security and
4362 only older versions of MSIE (4.0 for example) need it.
4365 *) Honor the no-xxx Configure options when creating .DEF files.
4368 *) Add PKCS#10 attributes to field table: challengePassword,
4369 unstructuredName and unstructuredAddress. These are taken from
4370 draft PKCS#9 v2.0 but are compatible with v1.2 provided no
4371 international characters are used.
4373 More changes to X509_ATTRIBUTE code: allow the setting of types
4374 based on strings. Remove the 'loc' parameter when adding
4375 attributes because these will be a SET OF encoding which is sorted
4379 *) Initial changes to the 'req' utility to allow request generation
4380 automation. This will allow an application to just generate a template
4381 file containing all the field values and have req construct the
4384 Initial support for X509_ATTRIBUTE handling. Stacks of these are
4385 used all over the place including certificate requests and PKCS#7
4386 structures. They are currently handled manually where necessary with
4387 some primitive wrappers for PKCS#7. The new functions behave in a
4388 manner analogous to the X509 extension functions: they allow
4389 attributes to be looked up by NID and added.
4391 Later something similar to the X509V3 code would be desirable to
4392 automatically handle the encoding, decoding and printing of the
4393 more complex types. The string types like challengePassword can
4394 be handled by the string table functions.
4396 Also modified the multi byte string table handling. Now there is
4397 a 'global mask' which masks out certain types. The table itself
4398 can use the flag STABLE_NO_MASK to ignore the mask setting: this
4399 is useful when for example there is only one permissible type
4400 (as in countryName) and using the mask might result in no valid
4404 *) Clean up 'Finished' handling, and add functions SSL_get_finished and
4405 SSL_get_peer_finished to allow applications to obtain the latest
4406 Finished messages sent to the peer or expected from the peer,
4407 respectively. (SSL_get_peer_finished is usually the Finished message
4408 actually received from the peer, otherwise the protocol will be aborted.)
4410 As the Finished message are message digests of the complete handshake
4411 (with a total of 192 bits for TLS 1.0 and more for SSL 3.0), they can
4412 be used for external authentication procedures when the authentication
4413 provided by SSL/TLS is not desired or is not enough.
4416 *) Enhanced support for Alpha Linux is added. Now ./config checks if
4417 the host supports BWX extension and if Compaq C is present on the
4418 $PATH. Just exploiting of the BWX extension results in 20-30%
4419 performance kick for some algorithms, e.g. DES and RC4 to mention
4420 a couple. Compaq C in turn generates ~20% faster code for MD5 and
4424 *) Add support for MS "fast SGC". This is arguably a violation of the
4425 SSL3/TLS protocol. Netscape SGC does two handshakes: the first with
4426 weak crypto and after checking the certificate is SGC a second one
4427 with strong crypto. MS SGC stops the first handshake after receiving
4428 the server certificate message and sends a second client hello. Since
4429 a server will typically do all the time consuming operations before
4430 expecting any further messages from the client (server key exchange
4431 is the most expensive) there is little difference between the two.
4433 To get OpenSSL to support MS SGC we have to permit a second client
4434 hello message after we have sent server done. In addition we have to
4435 reset the MAC if we do get this second client hello.
4438 *) Add a function 'd2i_AutoPrivateKey()' this will automatically decide
4439 if a DER encoded private key is RSA or DSA traditional format. Changed
4440 d2i_PrivateKey_bio() to use it. This is only needed for the "traditional"
4441 format DER encoded private key. Newer code should use PKCS#8 format which
4442 has the key type encoded in the ASN1 structure. Added DER private key
4443 support to pkcs8 application.
4446 *) SSL 3/TLS 1 servers now don't request certificates when an anonymous
4447 ciphersuites has been selected (as required by the SSL 3/TLS 1
4448 specifications). Exception: When SSL_VERIFY_FAIL_IF_NO_PEER_CERT
4449 is set, we interpret this as a request to violate the specification
4450 (the worst that can happen is a handshake failure, and 'correct'
4451 behaviour would result in a handshake failure anyway).
4454 *) In SSL_CTX_add_session, take into account that there might be multiple
4455 SSL_SESSION structures with the same session ID (e.g. when two threads
4456 concurrently obtain them from an external cache).
4457 The internal cache can handle only one SSL_SESSION with a given ID,
4458 so if there's a conflict, we now throw out the old one to achieve
4462 *) Add OIDs for idea and blowfish in CBC mode. This will allow both
4463 to be used in PKCS#5 v2.0 and S/MIME. Also add checking to
4464 some routines that use cipher OIDs: some ciphers do not have OIDs
4465 defined and so they cannot be used for S/MIME and PKCS#5 v2.0 for
4469 *) Simplify the trust setting structure and code. Now we just have
4470 two sequences of OIDs for trusted and rejected settings. These will
4471 typically have values the same as the extended key usage extension
4472 and any application specific purposes.
4474 The trust checking code now has a default behaviour: it will just
4475 check for an object with the same NID as the passed id. Functions can
4476 be provided to override either the default behaviour or the behaviour
4477 for a given id. SSL client, server and email already have functions
4478 in place for compatibility: they check the NID and also return "trusted"
4479 if the certificate is self signed.
4482 *) Add d2i,i2d bio/fp functions for PrivateKey: these convert the
4483 traditional format into an EVP_PKEY structure.
4486 *) Add a password callback function PEM_cb() which either prompts for
4487 a password if usr_data is NULL or otherwise assumes it is a null
4488 terminated password. Allow passwords to be passed on command line
4489 environment or config files in a few more utilities.
4492 *) Add a bunch of DER and PEM functions to handle PKCS#8 format private
4493 keys. Add some short names for PKCS#8 PBE algorithms and allow them
4494 to be specified on the command line for the pkcs8 and pkcs12 utilities.
4495 Update documentation.
4498 *) Support for ASN1 "NULL" type. This could be handled before by using
4499 ASN1_TYPE but there wasn't any function that would try to read a NULL
4500 and produce an error if it couldn't. For compatibility we also have
4501 ASN1_NULL_new() and ASN1_NULL_free() functions but these are faked and
4502 don't allocate anything because they don't need to.
4505 *) Initial support for MacOS is now provided. Examine INSTALL.MacOS
4507 [Andy Polyakov, Roy Woods <roy@centicsystems.ca>]
4509 *) Rebuild of the memory allocation routines used by OpenSSL code and
4510 possibly others as well. The purpose is to make an interface that
4511 provide hooks so anyone can build a separate set of allocation and
4512 deallocation routines to be used by OpenSSL, for example memory
4513 pool implementations, or something else, which was previously hard
4514 since Malloc(), Realloc() and Free() were defined as macros having
4515 the values malloc, realloc and free, respectively (except for Win32
4516 compilations). The same is provided for memory debugging code.
4517 OpenSSL already comes with functionality to find memory leaks, but
4518 this gives people a chance to debug other memory problems.
4520 With these changes, a new set of functions and macros have appeared:
4522 CRYPTO_set_mem_debug_functions() [F]
4523 CRYPTO_get_mem_debug_functions() [F]
4524 CRYPTO_dbg_set_options() [F]
4525 CRYPTO_dbg_get_options() [F]
4526 CRYPTO_malloc_debug_init() [M]
4528 The memory debug functions are NULL by default, unless the library
4529 is compiled with CRYPTO_MDEBUG or friends is defined. If someone
4530 wants to debug memory anyway, CRYPTO_malloc_debug_init() (which
4531 gives the standard debugging functions that come with OpenSSL) or
4532 CRYPTO_set_mem_debug_functions() (tells OpenSSL to use functions
4533 provided by the library user) must be used. When the standard
4534 debugging functions are used, CRYPTO_dbg_set_options can be used to
4535 request additional information:
4536 CRYPTO_dbg_set_options(V_CYRPTO_MDEBUG_xxx) corresponds to setting
4537 the CRYPTO_MDEBUG_xxx macro when compiling the library.
4539 Also, things like CRYPTO_set_mem_functions will always give the
4540 expected result (the new set of functions is used for allocation
4541 and deallocation) at all times, regardless of platform and compiler
4544 To finish it up, some functions that were never use in any other
4545 way than through macros have a new API and new semantic:
4548 CRYPTO_dbg_realloc()
4551 All macros of value have retained their old syntax.
4552 [Richard Levitte and Bodo Moeller]
4554 *) Some S/MIME fixes. The OID for SMIMECapabilities was wrong, the
4555 ordering of SMIMECapabilities wasn't in "strength order" and there
4556 was a missing NULL in the AlgorithmIdentifier for the SHA1 signature
4560 *) Some ASN1 types with illegal zero length encoding (INTEGER,
4561 ENUMERATED and OBJECT IDENTIFIER) choked the ASN1 routines.
4562 [Frans Heymans <fheymans@isaserver.be>, modified by Steve Henson]
4564 *) Merge in my S/MIME library for OpenSSL. This provides a simple
4565 S/MIME API on top of the PKCS#7 code, a MIME parser (with enough
4566 functionality to handle multipart/signed properly) and a utility
4567 called 'smime' to call all this stuff. This is based on code I
4568 originally wrote for Celo who have kindly allowed it to be
4569 included in OpenSSL.
4572 *) Add variants des_set_key_checked and des_set_key_unchecked of
4573 des_set_key (aka des_key_sched). Global variable des_check_key
4574 decides which of these is called by des_set_key; this way
4575 des_check_key behaves as it always did, but applications and
4576 the library itself, which was buggy for des_check_key == 1,
4577 have a cleaner way to pick the version they need.
4580 *) New function PKCS12_newpass() which changes the password of a
4584 *) Modify X509_TRUST and X509_PURPOSE so it also uses a static and
4585 dynamic mix. In both cases the ids can be used as an index into the
4586 table. Also modified the X509_TRUST_add() and X509_PURPOSE_add()
4587 functions so they accept a list of the field values and the
4588 application doesn't need to directly manipulate the X509_TRUST
4592 *) Modify the ASN1_STRING_TABLE stuff so it also uses bsearch and doesn't
4596 *) Modify the way the V3 extension code looks up extensions. This now
4597 works in a similar way to the object code: we have some "standard"
4598 extensions in a static table which is searched with OBJ_bsearch()
4599 and the application can add dynamic ones if needed. The file
4600 crypto/x509v3/ext_dat.h now has the info: this file needs to be
4601 updated whenever a new extension is added to the core code and kept
4602 in ext_nid order. There is a simple program 'tabtest.c' which checks
4603 this. New extensions are not added too often so this file can readily
4604 be maintained manually.
4606 There are two big advantages in doing things this way. The extensions
4607 can be looked up immediately and no longer need to be "added" using
4608 X509V3_add_standard_extensions(): this function now does nothing.
4609 [Side note: I get *lots* of email saying the extension code doesn't
4610 work because people forget to call this function]
4611 Also no dynamic allocation is done unless new extensions are added:
4612 so if we don't add custom extensions there is no need to call
4613 X509V3_EXT_cleanup().
4616 *) Modify enc utility's salting as follows: make salting the default. Add a
4617 magic header, so unsalted files fail gracefully instead of just decrypting
4618 to garbage. This is because not salting is a big security hole, so people
4619 should be discouraged from doing it.
4622 *) Fixes and enhancements to the 'x509' utility. It allowed a message
4623 digest to be passed on the command line but it only used this
4624 parameter when signing a certificate. Modified so all relevant
4625 operations are affected by the digest parameter including the
4626 -fingerprint and -x509toreq options. Also -x509toreq choked if a
4627 DSA key was used because it didn't fix the digest.
4630 *) Initial certificate chain verify code. Currently tests the untrusted
4631 certificates for consistency with the verify purpose (which is set
4632 when the X509_STORE_CTX structure is set up) and checks the pathlength.
4634 There is a NO_CHAIN_VERIFY compilation option to keep the old behaviour:
4635 this is because it will reject chains with invalid extensions whereas
4636 every previous version of OpenSSL and SSLeay made no checks at all.
4638 Trust code: checks the root CA for the relevant trust settings. Trust
4639 settings have an initial value consistent with the verify purpose: e.g.
4640 if the verify purpose is for SSL client use it expects the CA to be
4641 trusted for SSL client use. However the default value can be changed to
4642 permit custom trust settings: one example of this would be to only trust
4643 certificates from a specific "secure" set of CAs.
4645 Also added X509_STORE_CTX_new() and X509_STORE_CTX_free() functions
4646 which should be used for version portability: especially since the
4647 verify structure is likely to change more often now.
4649 SSL integration. Add purpose and trust to SSL_CTX and SSL and functions
4650 to set them. If not set then assume SSL clients will verify SSL servers
4653 Two new options to the verify program: -untrusted allows a set of
4654 untrusted certificates to be passed in and -purpose which sets the
4655 intended purpose of the certificate. If a purpose is set then the
4656 new chain verify code is used to check extension consistency.
4659 *) Support for the authority information access extension.
4662 *) Modify RSA and DSA PEM read routines to transparently handle
4663 PKCS#8 format private keys. New *_PUBKEY_* functions that handle
4664 public keys in a format compatible with certificate
4665 SubjectPublicKeyInfo structures. Unfortunately there were already
4666 functions called *_PublicKey_* which used various odd formats so
4667 these are retained for compatibility: however the DSA variants were
4668 never in a public release so they have been deleted. Changed dsa/rsa
4669 utilities to handle the new format: note no releases ever handled public
4670 keys so we should be OK.
4672 The primary motivation for this change is to avoid the same fiasco
4673 that dogs private keys: there are several incompatible private key
4674 formats some of which are standard and some OpenSSL specific and
4675 require various evil hacks to allow partial transparent handling and
4676 even then it doesn't work with DER formats. Given the option anything
4677 other than PKCS#8 should be dumped: but the other formats have to
4678 stay in the name of compatibility.
4680 With public keys and the benefit of hindsight one standard format
4681 is used which works with EVP_PKEY, RSA or DSA structures: though
4682 it clearly returns an error if you try to read the wrong kind of key.
4684 Added a -pubkey option to the 'x509' utility to output the public key.
4685 Also rename the EVP_PKEY_get_*() to EVP_PKEY_rget_*()
4686 (renamed to EVP_PKEY_get1_*() in the OpenSSL 0.9.5 release) and add
4687 EVP_PKEY_rset_*() functions (renamed to EVP_PKEY_set1_*())
4688 that do the same as the EVP_PKEY_assign_*() except they up the
4689 reference count of the added key (they don't "swallow" the
4693 *) Fixes to crypto/x509/by_file.c the code to read in certificates and
4694 CRLs would fail if the file contained no certificates or no CRLs:
4695 added a new function to read in both types and return the number
4696 read: this means that if none are read it will be an error. The
4697 DER versions of the certificate and CRL reader would always fail
4698 because it isn't possible to mix certificates and CRLs in DER format
4699 without choking one or the other routine. Changed this to just read
4700 a certificate: this is the best we can do. Also modified the code
4701 in apps/verify.c to take notice of return codes: it was previously
4702 attempting to read in certificates from NULL pointers and ignoring
4703 any errors: this is one reason why the cert and CRL reader seemed
4704 to work. It doesn't check return codes from the default certificate
4705 routines: these may well fail if the certificates aren't installed.
4708 *) Code to support otherName option in GeneralName.
4711 *) First update to verify code. Change the verify utility
4712 so it warns if it is passed a self signed certificate:
4713 for consistency with the normal behaviour. X509_verify
4714 has been modified to it will now verify a self signed
4715 certificate if *exactly* the same certificate appears
4716 in the store: it was previously impossible to trust a
4717 single self signed certificate. This means that:
4718 openssl verify ss.pem
4719 now gives a warning about a self signed certificate but
4720 openssl verify -CAfile ss.pem ss.pem
4724 *) For servers, store verify_result in SSL_SESSION data structure
4725 (and add it to external session representation).
4726 This is needed when client certificate verifications fails,
4727 but an application-provided verification callback (set by
4728 SSL_CTX_set_cert_verify_callback) allows accepting the session
4729 anyway (i.e. leaves x509_store_ctx->error != X509_V_OK
4730 but returns 1): When the session is reused, we have to set
4731 ssl->verify_result to the appropriate error code to avoid
4733 [Bodo Moeller, problem pointed out by Lutz Jaenicke]
4735 *) Fix a bug in the new PKCS#7 code: it didn't consider the
4736 case in PKCS7_dataInit() where the signed PKCS7 structure
4737 didn't contain any existing data because it was being created.
4738 [Po-Cheng Chen <pocheng@nst.com.tw>, slightly modified by Steve Henson]
4740 *) Add a salt to the key derivation routines in enc.c. This
4741 forms the first 8 bytes of the encrypted file. Also add a
4742 -S option to allow a salt to be input on the command line.
4745 *) New function X509_cmp(). Oddly enough there wasn't a function
4746 to compare two certificates. We do this by working out the SHA1
4747 hash and comparing that. X509_cmp() will be needed by the trust
4751 *) SSL_get1_session() is like SSL_get_session(), but increments
4752 the reference count in the SSL_SESSION returned.
4753 [Geoff Thorpe <geoff@eu.c2.net>]
4755 *) Fix for 'req': it was adding a null to request attributes.
4756 Also change the X509_LOOKUP and X509_INFO code to handle
4757 certificate auxiliary information.
4760 *) Add support for 40 and 64 bit RC2 and RC4 algorithms: document
4764 *) Add the possibility to add extra information to the memory leak
4765 detecting output, to form tracebacks, showing from where each
4766 allocation was originated: CRYPTO_push_info("constant string") adds
4767 the string plus current file name and line number to a per-thread
4768 stack, CRYPTO_pop_info() does the obvious, CRYPTO_remove_all_info()
4769 is like calling CYRPTO_pop_info() until the stack is empty.
4770 Also updated memory leak detection code to be multi-thread-safe.
4773 *) Add options -text and -noout to pkcs7 utility and delete the
4774 encryption options which never did anything. Update docs.
4777 *) Add options to some of the utilities to allow the pass phrase
4778 to be included on either the command line (not recommended on
4779 OSes like Unix) or read from the environment. Update the
4780 manpages and fix a few bugs.
4783 *) Add a few manpages for some of the openssl commands.
4786 *) Fix the -revoke option in ca. It was freeing up memory twice,
4787 leaking and not finding already revoked certificates.
4790 *) Extensive changes to support certificate auxiliary information.
4791 This involves the use of X509_CERT_AUX structure and X509_AUX
4792 functions. An X509_AUX function such as PEM_read_X509_AUX()
4793 can still read in a certificate file in the usual way but it
4794 will also read in any additional "auxiliary information". By
4795 doing things this way a fair degree of compatibility can be
4796 retained: existing certificates can have this information added
4797 using the new 'x509' options.
4799 Current auxiliary information includes an "alias" and some trust
4800 settings. The trust settings will ultimately be used in enhanced
4801 certificate chain verification routines: currently a certificate
4802 can only be trusted if it is self signed and then it is trusted
4806 *) Fix assembler for Alpha (tested only on DEC OSF not Linux or *BSD).
4807 The problem was that one of the replacement routines had not been working
4808 since SSLeay releases. For now the offending routine has been replaced
4809 with non-optimised assembler. Even so, this now gives around 95%
4810 performance improvement for 1024 bit RSA signs.
4813 *) Hack to fix PKCS#7 decryption when used with some unorthodox RC2
4814 handling. Most clients have the effective key size in bits equal to
4815 the key length in bits: so a 40 bit RC2 key uses a 40 bit (5 byte) key.
4816 A few however don't do this and instead use the size of the decrypted key
4817 to determine the RC2 key length and the AlgorithmIdentifier to determine
4818 the effective key length. In this case the effective key length can still
4819 be 40 bits but the key length can be 168 bits for example. This is fixed
4820 by manually forcing an RC2 key into the EVP_PKEY structure because the
4821 EVP code can't currently handle unusual RC2 key sizes: it always assumes
4822 the key length and effective key length are equal.
4825 *) Add a bunch of functions that should simplify the creation of
4826 X509_NAME structures. Now you should be able to do:
4827 X509_NAME_add_entry_by_txt(nm, "CN", MBSTRING_ASC, "Steve", -1, -1, 0);
4828 and have it automatically work out the correct field type and fill in
4829 the structures. The more adventurous can try:
4830 X509_NAME_add_entry_by_txt(nm, field, MBSTRING_UTF8, str, -1, -1, 0);
4831 and it will (hopefully) work out the correct multibyte encoding.
4834 *) Change the 'req' utility to use the new field handling and multibyte
4835 copy routines. Before the DN field creation was handled in an ad hoc
4836 way in req, ca, and x509 which was rather broken and didn't support
4837 BMPStrings or UTF8Strings. Since some software doesn't implement
4838 BMPStrings or UTF8Strings yet, they can be enabled using the config file
4839 using the dirstring_type option. See the new comment in the default
4840 openssl.cnf for more info.
4843 *) Make crypto/rand/md_rand.c more robust:
4844 - Assure unique random numbers after fork().
4845 - Make sure that concurrent threads access the global counter and
4846 md serializably so that we never lose entropy in them
4847 or use exactly the same state in multiple threads.
4848 Access to the large state is not always serializable because
4849 the additional locking could be a performance killer, and
4850 md should be large enough anyway.
4853 *) New file apps/app_rand.c with commonly needed functionality
4854 for handling the random seed file.
4856 Use the random seed file in some applications that previously did not:
4858 dsaparam -genkey (which also ignored its '-rand' option),
4861 x509 (when signing).
4862 Except on systems with /dev/urandom, it is crucial to have a random
4863 seed file at least for key creation, DSA signing, and for DH exchanges;
4864 for RSA signatures we could do without one.
4866 gendh and gendsa (unlike genrsa) used to read only the first byte
4867 of each file listed in the '-rand' option. The function as previously
4868 found in genrsa is now in app_rand.c and is used by all programs
4869 that support '-rand'.
4872 *) In RAND_write_file, use mode 0600 for creating files;
4873 don't just chmod when it may be too late.
4876 *) Report an error from X509_STORE_load_locations
4877 when X509_LOOKUP_load_file or X509_LOOKUP_add_dir failed.
4880 *) New function ASN1_mbstring_copy() this copies a string in either
4881 ASCII, Unicode, Universal (4 bytes per character) or UTF8 format
4882 into an ASN1_STRING type. A mask of permissible types is passed
4883 and it chooses the "minimal" type to use or an error if not type
4887 *) Add function equivalents to the various macros in asn1.h. The old
4888 macros are retained with an M_ prefix. Code inside the library can
4889 use the M_ macros. External code (including the openssl utility)
4890 should *NOT* in order to be "shared library friendly".
4893 *) Add various functions that can check a certificate's extensions
4894 to see if it usable for various purposes such as SSL client,
4895 server or S/MIME and CAs of these types. This is currently
4896 VERY EXPERIMENTAL but will ultimately be used for certificate chain
4897 verification. Also added a -purpose flag to x509 utility to
4898 print out all the purposes.
4901 *) Add a CRYPTO_EX_DATA to X509 certificate structure and associated
4905 *) New X509V3_{X509,CRL,REVOKED}_get_d2i() functions. These will search
4906 for, obtain and decode and extension and obtain its critical flag.
4907 This allows all the necessary extension code to be handled in a
4908 single function call.
4911 *) RC4 tune-up featuring 30-40% performance improvement on most RISC
4912 platforms. See crypto/rc4/rc4_enc.c for further details.
4915 *) New -noout option to asn1parse. This causes no output to be produced
4916 its main use is when combined with -strparse and -out to extract data
4917 from a file (which may not be in ASN.1 format).
4920 *) Fix for pkcs12 program. It was hashing an invalid certificate pointer
4921 when producing the local key id.
4922 [Richard Levitte <levitte@stacken.kth.se>]
4924 *) New option -dhparam in s_server. This allows a DH parameter file to be
4925 stated explicitly. If it is not stated then it tries the first server
4926 certificate file. The previous behaviour hard coded the filename
4930 *) Add -pubin and -pubout options to the rsa and dsa commands. These allow
4931 a public key to be input or output. For example:
4932 openssl rsa -in key.pem -pubout -out pubkey.pem
4933 Also added necessary DSA public key functions to handle this.
4936 *) Fix so PKCS7_dataVerify() doesn't crash if no certificates are contained
4937 in the message. This was handled by allowing
4938 X509_find_by_issuer_and_serial() to tolerate a NULL passed to it.
4939 [Steve Henson, reported by Sampo Kellomaki <sampo@mail.neuronio.pt>]
4941 *) Fix for bug in d2i_ASN1_bytes(): other ASN1 functions add an extra null
4942 to the end of the strings whereas this didn't. This would cause problems
4943 if strings read with d2i_ASN1_bytes() were later modified.
4944 [Steve Henson, reported by Arne Ansper <arne@ats.cyber.ee>]
4946 *) Fix for base64 decode bug. When a base64 bio reads only one line of
4947 data and it contains EOF it will end up returning an error. This is
4948 caused by input 46 bytes long. The cause is due to the way base64
4949 BIOs find the start of base64 encoded data. They do this by trying a
4950 trial decode on each line until they find one that works. When they
4951 do a flag is set and it starts again knowing it can pass all the
4952 data directly through the decoder. Unfortunately it doesn't reset
4953 the context it uses. This means that if EOF is reached an attempt
4954 is made to pass two EOFs through the context and this causes the
4955 resulting error. This can also cause other problems as well. As is
4956 usual with these problems it takes *ages* to find and the fix is
4957 trivial: move one line.
4958 [Steve Henson, reported by ian@uns.ns.ac.yu (Ivan Nejgebauer) ]
4960 *) Ugly workaround to get s_client and s_server working under Windows. The
4961 old code wouldn't work because it needed to select() on sockets and the
4962 tty (for keypresses and to see if data could be written). Win32 only
4963 supports select() on sockets so we select() with a 1s timeout on the
4964 sockets and then see if any characters are waiting to be read, if none
4965 are present then we retry, we also assume we can always write data to
4966 the tty. This isn't nice because the code then blocks until we've
4967 received a complete line of data and it is effectively polling the
4968 keyboard at 1s intervals: however it's quite a bit better than not
4969 working at all :-) A dedicated Windows application might handle this
4970 with an event loop for example.
4973 *) Enhance RSA_METHOD structure. Now there are two extra methods, rsa_sign
4974 and rsa_verify. When the RSA_FLAGS_SIGN_VER option is set these functions
4975 will be called when RSA_sign() and RSA_verify() are used. This is useful
4976 if rsa_pub_dec() and rsa_priv_enc() equivalents are not available.
4977 For this to work properly RSA_public_decrypt() and RSA_private_encrypt()
4978 should *not* be used: RSA_sign() and RSA_verify() must be used instead.
4979 This necessitated the support of an extra signature type NID_md5_sha1
4980 for SSL signatures and modifications to the SSL library to use it instead
4981 of calling RSA_public_decrypt() and RSA_private_encrypt().
4984 *) Add new -verify -CAfile and -CApath options to the crl program, these
4985 will lookup a CRL issuers certificate and verify the signature in a
4986 similar way to the verify program. Tidy up the crl program so it
4987 no longer accesses structures directly. Make the ASN1 CRL parsing a bit
4988 less strict. It will now permit CRL extensions even if it is not
4989 a V2 CRL: this will allow it to tolerate some broken CRLs.
4992 *) Initialize all non-automatic variables each time one of the openssl
4993 sub-programs is started (this is necessary as they may be started
4994 multiple times from the "OpenSSL>" prompt).
4995 [Lennart Bang, Bodo Moeller]
4997 *) Preliminary compilation option RSA_NULL which disables RSA crypto without
4998 removing all other RSA functionality (this is what NO_RSA does). This
4999 is so (for example) those in the US can disable those operations covered
5000 by the RSA patent while allowing storage and parsing of RSA keys and RSA
5004 *) Non-copying interface to BIO pairs.
5005 (still largely untested)
5008 *) New function ANS1_tag2str() to convert an ASN1 tag to a descriptive
5009 ASCII string. This was handled independently in various places before.
5012 *) New functions UTF8_getc() and UTF8_putc() that parse and generate
5013 UTF8 strings a character at a time.
5016 *) Use client_version from client hello to select the protocol
5017 (s23_srvr.c) and for RSA client key exchange verification
5018 (s3_srvr.c), as required by the SSL 3.0/TLS 1.0 specifications.
5021 *) Add various utility functions to handle SPKACs, these were previously
5022 handled by poking round in the structure internals. Added new function
5023 NETSCAPE_SPKI_print() to print out SPKAC and a new utility 'spkac' to
5024 print, verify and generate SPKACs. Based on an original idea from
5025 Massimiliano Pala <madwolf@comune.modena.it> but extensively modified.
5028 *) RIPEMD160 is operational on all platforms and is back in 'make test'.
5031 *) Allow the config file extension section to be overwritten on the
5032 command line. Based on an original idea from Massimiliano Pala
5033 <madwolf@comune.modena.it>. The new option is called -extensions
5034 and can be applied to ca, req and x509. Also -reqexts to override
5035 the request extensions in req and -crlexts to override the crl extensions
5039 *) Add new feature to the SPKAC handling in ca. Now you can include
5040 the same field multiple times by preceding it by "XXXX." for example:
5043 this is the same syntax as used in the req config file.
5046 *) Allow certificate extensions to be added to certificate requests. These
5047 are specified in a 'req_extensions' option of the req section of the
5048 config file. They can be printed out with the -text option to req but
5049 are otherwise ignored at present.
5052 *) Fix a horrible bug in enc_read() in crypto/evp/bio_enc.c: if the first
5053 data read consists of only the final block it would not decrypted because
5054 EVP_CipherUpdate() would correctly report zero bytes had been decrypted.
5055 A misplaced 'break' also meant the decrypted final block might not be
5056 copied until the next read.
5059 *) Initial support for DH_METHOD. Again based on RSA_METHOD. Also added
5060 a few extra parameters to the DH structure: these will be useful if
5061 for example we want the value of 'q' or implement X9.42 DH.
5064 *) Initial support for DSA_METHOD. This is based on the RSA_METHOD and
5065 provides hooks that allow the default DSA functions or functions on a
5066 "per key" basis to be replaced. This allows hardware acceleration and
5067 hardware key storage to be handled without major modification to the
5068 library. Also added low level modexp hooks and CRYPTO_EX structure and
5069 associated functions.
5072 *) Add a new flag to memory BIOs, BIO_FLAG_MEM_RDONLY. This marks the BIO
5073 as "read only": it can't be written to and the buffer it points to will
5074 not be freed. Reading from a read only BIO is much more efficient than
5075 a normal memory BIO. This was added because there are several times when
5076 an area of memory needs to be read from a BIO. The previous method was
5077 to create a memory BIO and write the data to it, this results in two
5078 copies of the data and an O(n^2) reading algorithm. There is a new
5079 function BIO_new_mem_buf() which creates a read only memory BIO from
5080 an area of memory. Also modified the PKCS#7 routines to use read only
5084 *) Bugfix: ssl23_get_client_hello did not work properly when called in
5085 state SSL23_ST_SR_CLNT_HELLO_B, i.e. when the first 7 bytes of
5086 a SSLv2-compatible client hello for SSLv3 or TLSv1 could be read,
5087 but a retry condition occured while trying to read the rest.
5090 *) The PKCS7_ENC_CONTENT_new() function was setting the content type as
5091 NID_pkcs7_encrypted by default: this was wrong since this should almost
5092 always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle
5093 the encrypted data type: this is a more sensible place to put it and it
5094 allows the PKCS#12 code to be tidied up that duplicated this
5098 *) Changed obj_dat.pl script so it takes its input and output files on
5099 the command line. This should avoid shell escape redirection problems
5103 *) Initial support for certificate extension requests, these are included
5104 in things like Xenroll certificate requests. Included functions to allow
5105 extensions to be obtained and added.
5108 *) -crlf option to s_client and s_server for sending newlines as
5109 CRLF (as required by many protocols).
5112 Changes between 0.9.3a and 0.9.4 [09 Aug 1999]
5114 *) Install libRSAglue.a when OpenSSL is built with RSAref.
5115 [Ralf S. Engelschall]
5117 *) A few more ``#ifndef NO_FP_API / #endif'' pairs for consistency.
5118 [Andrija Antonijevic <TheAntony2@bigfoot.com>]
5120 *) Fix -startdate and -enddate (which was missing) arguments to 'ca'
5124 *) New function DSA_dup_DH, which duplicates DSA parameters/keys as
5125 DH parameters/keys (q is lost during that conversion, but the resulting
5126 DH parameters contain its length).
5128 For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is
5129 much faster than DH_generate_parameters (which creates parameters
5130 where p = 2*q + 1), and also the smaller q makes DH computations
5131 much more efficient (160-bit exponentiation instead of 1024-bit
5132 exponentiation); so this provides a convenient way to support DHE
5133 ciphersuites in SSL/TLS servers (see ssl/ssltest.c). It is of
5134 utter importance to use
5135 SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
5137 SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
5138 when such DH parameters are used, because otherwise small subgroup
5139 attacks may become possible!
5142 *) Avoid memory leak in i2d_DHparams.
5145 *) Allow the -k option to be used more than once in the enc program:
5146 this allows the same encrypted message to be read by multiple recipients.
5149 *) New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts
5150 an ASN1_OBJECT to a text string. If the "no_name" parameter is set then
5151 it will always use the numerical form of the OID, even if it has a short
5155 *) Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp
5156 method only got called if p,q,dmp1,dmq1,iqmp components were present,
5157 otherwise bn_mod_exp was called. In the case of hardware keys for example
5158 no private key components need be present and it might store extra data
5159 in the RSA structure, which cannot be accessed from bn_mod_exp.
5160 By setting RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for
5161 private key operations.
5164 *) Added support for SPARC Linux.
5167 *) pem_password_cb function type incompatibly changed from
5168 typedef int pem_password_cb(char *buf, int size, int rwflag);
5170 ....(char *buf, int size, int rwflag, void *userdata);
5171 so that applications can pass data to their callbacks:
5172 The PEM[_ASN1]_{read,write}... functions and macros now take an
5173 additional void * argument, which is just handed through whenever
5174 the password callback is called.
5175 [Damien Miller <dmiller@ilogic.com.au>; tiny changes by Bodo Moeller]
5177 New function SSL_CTX_set_default_passwd_cb_userdata.
5179 Compatibility note: As many C implementations push function arguments
5180 onto the stack in reverse order, the new library version is likely to
5181 interoperate with programs that have been compiled with the old
5182 pem_password_cb definition (PEM_whatever takes some data that
5183 happens to be on the stack as its last argument, and the callback
5184 just ignores this garbage); but there is no guarantee whatsoever that
5187 *) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=...
5188 (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused
5189 problems not only on Windows, but also on some Unix platforms.
5190 To avoid problematic command lines, these definitions are now in an
5191 auto-generated file crypto/buildinf.h (created by crypto/Makefile.ssl
5192 for standard "make" builds, by util/mk1mf.pl for "mk1mf" builds).
5195 *) MIPS III/IV assembler module is reimplemented.
5198 *) More DES library cleanups: remove references to srand/rand and
5199 delete an unused file.
5202 *) Add support for the the free Netwide assembler (NASM) under Win32,
5203 since not many people have MASM (ml) and it can be hard to obtain.
5204 This is currently experimental but it seems to work OK and pass all
5205 the tests. Check out INSTALL.W32 for info.
5208 *) Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections
5209 without temporary keys kept an extra copy of the server key,
5210 and connections with temporary keys did not free everything in case
5214 *) New function RSA_check_key and new openssl rsa option -check
5215 for verifying the consistency of RSA keys.
5216 [Ulf Moeller, Bodo Moeller]
5218 *) Various changes to make Win32 compile work:
5219 1. Casts to avoid "loss of data" warnings in p5_crpt2.c
5220 2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned
5221 comparison" warnings.
5222 3. Add sk_<TYPE>_sort to DEF file generator and do make update.
5225 *) Add a debugging option to PKCS#5 v2 key generation function: when
5226 you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and
5227 derived keys are printed to stderr.
5230 *) Copy the flags in ASN1_STRING_dup().
5231 [Roman E. Pavlov <pre@mo.msk.ru>]
5233 *) The x509 application mishandled signing requests containing DSA
5234 keys when the signing key was also DSA and the parameters didn't match.
5236 It was supposed to omit the parameters when they matched the signing key:
5237 the verifying software was then supposed to automatically use the CA's
5238 parameters if they were absent from the end user certificate.
5240 Omitting parameters is no longer recommended. The test was also
5241 the wrong way round! This was probably due to unusual behaviour in
5242 EVP_cmp_parameters() which returns 1 if the parameters match.
5243 This meant that parameters were omitted when they *didn't* match and
5244 the certificate was useless. Certificates signed with 'ca' didn't have
5246 [Steve Henson, reported by Doug Erickson <Doug.Erickson@Part.NET>]
5248 *) Memory leak checking (-DCRYPTO_MDEBUG) had some problems.
5249 The interface is as follows:
5250 Applications can use
5251 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(),
5252 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop();
5253 "off" is now the default.
5254 The library internally uses
5255 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(),
5256 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on()
5257 to disable memory-checking temporarily.
5259 Some inconsistent states that previously were possible (and were
5260 even the default) are now avoided.
5262 -DCRYPTO_MDEBUG_TIME is new and additionally stores the current time
5263 with each memory chunk allocated; this is occasionally more helpful
5264 than just having a counter.
5266 -DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID.
5268 -DCRYPTO_MDEBUG_ALL enables all of the above, plus any future
5272 *) Introduce "mode" for SSL structures (with defaults in SSL_CTX),
5273 which largely parallels "options", but is for changing API behaviour,
5274 whereas "options" are about protocol behaviour.
5275 Initial "mode" flags are:
5277 SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when
5278 a single record has been written.
5279 SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write
5280 retries use the same buffer location.
5281 (But all of the contents must be
5285 *) Bugfix: SSL_set_options ignored its parameter, only SSL_CTX_set_options
5288 *) Fix problems with no-hmac etc.
5289 [Ulf Möller, pointed out by Brian Wellington <bwelling@tislabs.com>]
5291 *) New functions RSA_get_default_method(), RSA_set_method() and
5292 RSA_get_method(). These allows replacement of RSA_METHODs without having
5293 to mess around with the internals of an RSA structure.
5296 *) Fix memory leaks in DSA_do_sign and DSA_is_prime.
5297 Also really enable memory leak checks in openssl.c and in some
5299 [Chad C. Mulligan, Bodo Moeller]
5301 *) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess
5302 up the length of negative integers. This has now been simplified to just
5303 store the length when it is first determined and use it later, rather
5304 than trying to keep track of where data is copied and updating it to
5306 [Steve Henson, reported by Brien Wheeler
5307 <bwheeler@authentica-security.com>]
5309 *) Add a new function PKCS7_signatureVerify. This allows the verification
5310 of a PKCS#7 signature but with the signing certificate passed to the
5311 function itself. This contrasts with PKCS7_dataVerify which assumes the
5312 certificate is present in the PKCS#7 structure. This isn't always the
5313 case: certificates can be omitted from a PKCS#7 structure and be
5314 distributed by "out of band" means (such as a certificate database).
5317 *) Complete the PEM_* macros with DECLARE_PEM versions to replace the
5318 function prototypes in pem.h, also change util/mkdef.pl to add the
5319 necessary function names.
5322 *) mk1mf.pl (used by Windows builds) did not properly read the
5323 options set by Configure in the top level Makefile, and Configure
5324 was not even able to write more than one option correctly.
5325 Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended.
5328 *) New functions CONF_load_bio() and CONF_load_fp() to allow a config
5329 file to be loaded from a BIO or FILE pointer. The BIO version will
5330 for example allow memory BIOs to contain config info.
5333 *) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS.
5334 Whoever hopes to achieve shared-library compatibility across versions
5335 must use this, not the compile-time macro.
5336 (Exercise 0.9.4: Which is the minimum library version required by
5338 Note: All this applies only to multi-threaded programs, others don't
5342 *) Add missing case to s3_clnt.c state machine -- one of the new SSL tests
5343 through a BIO pair triggered the default case, i.e.
5344 SSLerr(...,SSL_R_UNKNOWN_STATE).
5347 *) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications
5348 can use the SSL library even if none of the specific BIOs is
5352 *) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value
5353 for the encoded length.
5354 [Jeon KyoungHo <khjeon@sds.samsung.co.kr>]
5356 *) Add initial documentation of the X509V3 functions.
5359 *) Add a new pair of functions PEM_write_PKCS8PrivateKey() and
5360 PEM_write_bio_PKCS8PrivateKey() that are equivalent to
5361 PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more
5362 secure PKCS#8 private key format with a high iteration count.
5365 *) Fix determination of Perl interpreter: A perl or perl5
5366 _directory_ in $PATH was also accepted as the interpreter.
5367 [Ralf S. Engelschall]
5369 *) Fix demos/sign/sign.c: well there wasn't anything strictly speaking
5370 wrong with it but it was very old and did things like calling
5371 PEM_ASN1_read() directly and used MD5 for the hash not to mention some
5375 *) Fix demos/selfsign.c: it used obsolete and deleted functions, changed
5376 to use the new extension code.
5379 *) Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c
5380 with macros. This should make it easier to change their form, add extra
5381 arguments etc. Fix a few PEM prototypes which didn't have cipher as a
5385 *) Add to configuration table a new entry that can specify an alternative
5386 name for unistd.h (for pre-POSIX systems); we need this for NeXTstep,
5387 according to Mark Crispin <MRC@Panda.COM>.
5391 *) DES CBC did not update the IV. Weird.
5394 des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does.
5395 Changing the behaviour of the former might break existing programs --
5396 where IV updating is needed, des_ncbc_encrypt can be used.
5399 *) When bntest is run from "make test" it drives bc to check its
5400 calculations, as well as internally checking them. If an internal check
5401 fails, it needs to cause bc to give a non-zero result or make test carries
5402 on without noticing the failure. Fixed.
5405 *) DES library cleanups.
5408 *) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be
5409 used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit
5410 ciphers. NOTE: although the key derivation function has been verified
5411 against some published test vectors it has not been extensively tested
5412 yet. Added a -v2 "cipher" option to pkcs8 application to allow the use
5416 *) Instead of "mkdir -p", which is not fully portable, use new
5417 Perl script "util/mkdir-p.pl".
5420 *) Rewrite the way password based encryption (PBE) is handled. It used to
5421 assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter
5422 structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms
5423 but doesn't apply to PKCS#5 v2.0 where it can be something else. Now
5424 the 'parameter' field of the AlgorithmIdentifier is passed to the
5425 underlying key generation function so it must do its own ASN1 parsing.
5426 This has also changed the EVP_PBE_CipherInit() function which now has a
5427 'parameter' argument instead of literal salt and iteration count values
5428 and the function EVP_PBE_ALGOR_CipherInit() has been deleted.
5431 *) Support for PKCS#5 v1.5 compatible password based encryption algorithms
5432 and PKCS#8 functionality. New 'pkcs8' application linked to openssl.
5433 Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE
5434 KEY" because this clashed with PKCS#8 unencrypted string. Since this
5435 value was just used as a "magic string" and not used directly its
5436 value doesn't matter.
5439 *) Introduce some semblance of const correctness to BN. Shame C doesn't
5443 *) "linux-sparc64" configuration (ultrapenguin).
5444 [Ray Miller <ray.miller@oucs.ox.ac.uk>]
5445 "linux-sparc" configuration.
5446 [Christian Forster <fo@hawo.stw.uni-erlangen.de>]
5448 *) config now generates no-xxx options for missing ciphers.
5451 *) Support the EBCDIC character set (work in progress).
5452 File ebcdic.c not yet included because it has a different license.
5453 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
5455 *) Support BS2000/OSD-POSIX.
5456 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
5458 *) Make callbacks for key generation use void * instead of char *.
5461 *) Make S/MIME samples compile (not yet tested).
5464 *) Additional typesafe stacks.
5467 *) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x).
5471 Changes between 0.9.3 and 0.9.3a [29 May 1999]
5473 *) New configuration variant "sco5-gcc".
5475 *) Updated some demos.
5476 [Sean O Riordain, Wade Scholine]
5478 *) Add missing BIO_free at exit of pkcs12 application.
5481 *) Fix memory leak in conf.c.
5484 *) Updates for Win32 to assembler version of MD5.
5487 *) Set #! path to perl in apps/der_chop to where we found it
5488 instead of using a fixed path.
5491 *) SHA library changes for irix64-mips4-cc.
5494 *) Improvements for VMS support.
5498 Changes between 0.9.2b and 0.9.3 [24 May 1999]
5500 *) Bignum library bug fix. IRIX 6 passes "make test" now!
5501 This also avoids the problems with SC4.2 and unpatched SC5.
5502 [Andy Polyakov <appro@fy.chalmers.se>]
5504 *) New functions sk_num, sk_value and sk_set to replace the previous macros.
5505 These are required because of the typesafe stack would otherwise break
5506 existing code. If old code used a structure member which used to be STACK
5507 and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with
5508 sk_num or sk_value it would produce an error because the num, data members
5509 are not present in STACK_OF. Now it just produces a warning. sk_set
5510 replaces the old method of assigning a value to sk_value
5511 (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code
5512 that does this will no longer work (and should use sk_set instead) but
5513 this could be regarded as a "questionable" behaviour anyway.
5516 *) Fix most of the other PKCS#7 bugs. The "experimental" code can now
5517 correctly handle encrypted S/MIME data.
5520 *) Change type of various DES function arguments from des_cblock
5521 (which means, in function argument declarations, pointer to char)
5522 to des_cblock * (meaning pointer to array with 8 char elements),
5523 which allows the compiler to do more typechecking; it was like
5524 that back in SSLeay, but with lots of ugly casts.
5526 Introduce new type const_des_cblock.
5529 *) Reorganise the PKCS#7 library and get rid of some of the more obvious
5530 problems: find RecipientInfo structure that matches recipient certificate
5531 and initialise the ASN1 structures properly based on passed cipher.
5534 *) Belatedly make the BN tests actually check the results.
5537 *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion
5538 to and from BNs: it was completely broken. New compilation option
5539 NEG_PUBKEY_BUG to allow for some broken certificates that encode public
5540 key elements as negative integers.
5543 *) Reorganize and speed up MD5.
5544 [Andy Polyakov <appro@fy.chalmers.se>]
5547 [Richard Levitte <richard@levitte.org>]
5549 *) New option -out to asn1parse to allow the parsed structure to be
5550 output to a file. This is most useful when combined with the -strparse
5551 option to examine the output of things like OCTET STRINGS.
5554 *) Make SSL library a little more fool-proof by not requiring any longer
5555 that SSL_set_{accept,connect}_state be called before
5556 SSL_{accept,connect} may be used (SSL_set_..._state is omitted
5557 in many applications because usually everything *appeared* to work as
5558 intended anyway -- now it really works as intended).
5561 *) Move openssl.cnf out of lib/.
5564 *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall
5565 -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
5566 -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+
5567 [Ralf S. Engelschall]
5569 *) Various fixes to the EVP and PKCS#7 code. It may now be able to
5570 handle PKCS#7 enveloped data properly.
5571 [Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve]
5573 *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
5574 copying pointers. The cert_st handling is changed by this in
5575 various ways (and thus what used to be known as ctx->default_cert
5576 is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
5577 any longer when s->cert does not give us what we need).
5578 ssl_cert_instantiate becomes obsolete by this change.
5579 As soon as we've got the new code right (possibly it already is?),
5580 we have solved a couple of bugs of the earlier code where s->cert
5581 was used as if it could not have been shared with other SSL structures.
5583 Note that using the SSL API in certain dirty ways now will result
5584 in different behaviour than observed with earlier library versions:
5585 Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
5586 does not influence s as it used to.
5588 In order to clean up things more thoroughly, inside SSL_SESSION
5589 we don't use CERT any longer, but a new structure SESS_CERT
5590 that holds per-session data (if available); currently, this is
5591 the peer's certificate chain and, for clients, the server's certificate
5592 and temporary key. CERT holds only those values that can have
5593 meaningful defaults in an SSL_CTX.
5596 *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure
5597 from the internal representation. Various PKCS#7 fixes: remove some
5598 evil casts and set the enc_dig_alg field properly based on the signing
5602 *) Allow PKCS#12 password to be set from the command line or the
5603 environment. Let 'ca' get its config file name from the environment
5604 variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req'
5608 *) Allow certificate policies extension to use an IA5STRING for the
5609 organization field. This is contrary to the PKIX definition but
5610 VeriSign uses it and IE5 only recognises this form. Document 'x509'
5614 *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic,
5615 without disallowing inline assembler and the like for non-pedantic builds.
5618 *) Support Borland C++ builder.
5619 [Janez Jere <jj@void.si>, modified by Ulf Möller]
5624 *) SHA-1 cleanups and performance enhancements.
5625 [Andy Polyakov <appro@fy.chalmers.se>]
5627 *) Sparc v8plus assembler for the bignum library.
5628 [Andy Polyakov <appro@fy.chalmers.se>]
5630 *) Accept any -xxx and +xxx compiler options in Configure.
5633 *) Update HPUX configuration.
5636 *) Add missing sk_<type>_unshift() function to safestack.h
5637 [Ralf S. Engelschall]
5639 *) New function SSL_CTX_use_certificate_chain_file that sets the
5640 "extra_cert"s in addition to the certificate. (This makes sense
5641 only for "PEM" format files, as chains as a whole are not
5645 *) Support verify_depth from the SSL API.
5646 x509_vfy.c had what can be considered an off-by-one-error:
5647 Its depth (which was not part of the external interface)
5648 was actually counting the number of certificates in a chain;
5649 now it really counts the depth.
5652 *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used
5653 instead of X509err, which often resulted in confusing error
5654 messages since the error codes are not globally unique
5655 (e.g. an alleged error in ssl3_accept when a certificate
5656 didn't match the private key).
5658 *) New function SSL_CTX_set_session_id_context that allows to set a default
5659 value (so that you don't need SSL_set_session_id_context for each
5660 connection using the SSL_CTX).
5663 *) OAEP decoding bug fix.
5666 *) Support INSTALL_PREFIX for package builders, as proposed by
5670 *) New Configure options "threads" and "no-threads". For systems
5671 where the proper compiler options are known (currently Solaris
5672 and Linux), "threads" is the default.
5675 *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
5678 *) Install various scripts to $(OPENSSLDIR)/misc, not to
5679 $(INSTALLTOP)/bin -- they shouldn't clutter directories
5680 such as /usr/local/bin.
5683 *) "make linux-shared" to build shared libraries.
5684 [Niels Poppe <niels@netbox.org>]
5686 *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
5689 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
5690 extension adding in x509 utility.
5693 *) Remove NOPROTO sections and error code comments.
5696 *) Partial rewrite of the DEF file generator to now parse the ANSI
5700 *) New Configure options --prefix=DIR and --openssldir=DIR.
5703 *) Complete rewrite of the error code script(s). It is all now handled
5704 by one script at the top level which handles error code gathering,
5705 header rewriting and C source file generation. It should be much better
5706 than the old method: it now uses a modified version of Ulf's parser to
5707 read the ANSI prototypes in all header files (thus the old K&R definitions
5708 aren't needed for error creation any more) and do a better job of
5709 translating function codes into names. The old 'ASN1 error code imbedded
5710 in a comment' is no longer necessary and it doesn't use .err files which
5711 have now been deleted. Also the error code call doesn't have to appear all
5712 on one line (which resulted in some large lines...).
5715 *) Change #include filenames from <foo.h> to <openssl/foo.h>.
5718 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
5719 0 (which usually indicates a closed connection), but continue reading.
5722 *) Fix some race conditions.
5725 *) Add support for CRL distribution points extension. Add Certificate
5726 Policies and CRL distribution points documentation.
5729 *) Move the autogenerated header file parts to crypto/opensslconf.h.
5732 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
5733 8 of keying material. Merlin has also confirmed interop with this fix
5734 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
5735 [Merlin Hughes <merlin@baltimore.ie>]
5737 *) Fix lots of warnings.
5738 [Richard Levitte <levitte@stacken.kth.se>]
5740 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
5741 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
5742 [Richard Levitte <levitte@stacken.kth.se>]
5744 *) Fix problems with sizeof(long) == 8.
5745 [Andy Polyakov <appro@fy.chalmers.se>]
5747 *) Change functions to ANSI C.
5750 *) Fix typos in error codes.
5751 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
5753 *) Remove defunct assembler files from Configure.
5756 *) SPARC v8 assembler BIGNUM implementation.
5757 [Andy Polyakov <appro@fy.chalmers.se>]
5759 *) Support for Certificate Policies extension: both print and set.
5760 Various additions to support the r2i method this uses.
5763 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
5764 return a const string when you are expecting an allocated buffer.
5767 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
5768 types DirectoryString and DisplayText.
5771 *) Add code to allow r2i extensions to access the configuration database,
5772 add an LHASH database driver and add several ctx helper functions.
5775 *) Fix an evil bug in bn_expand2() which caused various BN functions to
5776 fail when they extended the size of a BIGNUM.
5779 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
5780 support typesafe stack.
5783 *) Fix typo in SSL_[gs]et_options().
5784 [Nils Frostberg <nils@medcom.se>]
5786 *) Delete various functions and files that belonged to the (now obsolete)
5787 old X509V3 handling code.
5790 *) New Configure option "rsaref".
5793 *) Don't auto-generate pem.h.
5796 *) Introduce type-safe ASN.1 SETs.
5799 *) Convert various additional casted stacks to type-safe STACK_OF() variants.
5800 [Ben Laurie, Ralf S. Engelschall, Steve Henson]
5802 *) Introduce type-safe STACKs. This will almost certainly break lots of code
5803 that links with OpenSSL (well at least cause lots of warnings), but fear
5804 not: the conversion is trivial, and it eliminates loads of evil casts. A
5805 few STACKed things have been converted already. Feel free to convert more.
5806 In the fullness of time, I'll do away with the STACK type altogether.
5809 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
5810 specified in <certfile> by updating the entry in the index.txt file.
5811 This way one no longer has to edit the index.txt file manually for
5812 revoking a certificate. The -revoke option does the gory details now.
5813 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
5815 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
5816 `-text' option at all and this way the `-noout -text' combination was
5817 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
5818 [Ralf S. Engelschall]
5820 *) Make sure a corresponding plain text error message exists for the
5821 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
5822 verify callback function determined that a certificate was revoked.
5823 [Ralf S. Engelschall]
5825 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
5826 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
5827 all available cipers including rc5, which was forgotten until now.
5828 In order to let the testing shell script know which algorithms
5829 are available, a new (up to now undocumented) command
5830 "openssl list-cipher-commands" is used.
5833 *) Bugfix: s_client occasionally would sleep in select() when
5834 it should have checked SSL_pending() first.
5837 *) New functions DSA_do_sign and DSA_do_verify to provide access to
5838 the raw DSA values prior to ASN.1 encoding.
5841 *) Tweaks to Configure
5842 [Niels Poppe <niels@netbox.org>]
5844 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
5848 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
5851 *) New config option to avoid instructions that are illegal on the 80386.
5852 The default code is faster, but requires at least a 486.
5855 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
5856 SSL2_SERVER_VERSION (not used at all) macros, which are now the
5857 same as SSL2_VERSION anyway.
5860 *) New "-showcerts" option for s_client.
5863 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
5864 application. Various cleanups and fixes.
5867 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
5868 modify error routines to work internally. Add error codes and PBE init
5869 to library startup routines.
5872 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
5873 packing functions to asn1 and evp. Changed function names and error
5874 codes along the way.
5877 *) PKCS12 integration: and so it begins... First of several patches to
5878 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
5879 objects to objects.h
5882 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
5883 and display support for Thawte strong extranet extension.
5886 *) Add LinuxPPC support.
5887 [Jeff Dubrule <igor@pobox.org>]
5889 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
5890 bn_div_words in alpha.s.
5891 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
5893 *) Make sure the RSA OAEP test is skipped under -DRSAref because
5894 OAEP isn't supported when OpenSSL is built with RSAref.
5895 [Ulf Moeller <ulf@fitug.de>]
5897 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
5898 so they no longer are missing under -DNOPROTO.
5899 [Soren S. Jorvang <soren@t.dk>]
5902 Changes between 0.9.1c and 0.9.2b [22 Mar 1999]
5904 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
5905 doesn't work when the session is reused. Coming soon!
5908 *) Fix a security hole, that allows sessions to be reused in the wrong
5909 context thus bypassing client cert protection! All software that uses
5910 client certs and session caches in multiple contexts NEEDS PATCHING to
5911 allow session reuse! A fuller solution is in the works.
5912 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
5914 *) Some more source tree cleanups (removed obsolete files
5915 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
5916 permission on "config" script to be executable) and a fix for the INSTALL
5918 [Ulf Moeller <ulf@fitug.de>]
5920 *) Remove some legacy and erroneous uses of malloc, free instead of
5922 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
5924 *) Make rsa_oaep_test return non-zero on error.
5925 [Ulf Moeller <ulf@fitug.de>]
5927 *) Add support for native Solaris shared libraries. Configure
5928 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
5929 if someone would make that last step automatic.
5930 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
5932 *) ctx_size was not built with the right compiler during "make links". Fixed.
5935 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
5936 except NULL ciphers". This means the default cipher list will no longer
5937 enable NULL ciphers. They need to be specifically enabled e.g. with
5938 the string "DEFAULT:eNULL".
5941 *) Fix to RSA private encryption routines: if p < q then it would
5942 occasionally produce an invalid result. This will only happen with
5943 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
5946 *) Be less restrictive and allow also `perl util/perlpath.pl
5947 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
5948 because this way one can also use an interpreter named `perl5' (which is
5949 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
5950 installed as `perl').
5951 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
5953 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
5954 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
5956 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
5957 advapi32.lib to Win32 build and change the pem test comparision
5958 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
5959 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
5960 and crypto/des/ede_cbcm_enc.c.
5963 *) DES quad checksum was broken on big-endian architectures. Fixed.
5966 *) Comment out two functions in bio.h that aren't implemented. Fix up the
5967 Win32 test batch file so it (might) work again. The Win32 test batch file
5968 is horrible: I feel ill....
5971 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
5972 in e_os.h. Audit of header files to check ANSI and non ANSI
5973 sections: 10 functions were absent from non ANSI section and not exported
5974 from Windows DLLs. Fixed up libeay.num for new functions.
5977 *) Make `openssl version' output lines consistent.
5978 [Ralf S. Engelschall]
5980 *) Fix Win32 symbol export lists for BIO functions: Added
5981 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
5982 to ms/libeay{16,32}.def.
5983 [Ralf S. Engelschall]
5985 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
5986 fine under Unix and passes some trivial tests I've now added. But the
5987 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
5988 added to make sure no one expects that this stuff really works in the
5989 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
5990 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
5992 [Ralf S. Engelschall]
5994 *) Fix the generation of two part addresses in perl.
5995 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
5997 *) Add config entry for Linux on MIPS.
5998 [John Tobey <jtobey@channel1.com>]
6000 *) Make links whenever Configure is run, unless we are on Windoze.
6003 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
6004 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
6008 *) Add a useful kludge to allow package maintainers to specify compiler and
6009 other platforms details on the command line without having to patch the
6010 Configure script everytime: One now can use ``perl Configure
6011 <id>:<details>'', i.e. platform ids are allowed to have details appended
6012 to them (seperated by colons). This is treated as there would be a static
6013 pre-configured entry in Configure's %table under key <id> with value
6014 <details> and ``perl Configure <id>'' is called. So, when you want to
6015 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
6016 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
6017 now, which overrides the FreeBSD-elf entry on-the-fly.
6018 [Ralf S. Engelschall]
6020 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
6023 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
6024 on the `perl Configure ...' command line. This way one can compile
6025 OpenSSL libraries with Position Independent Code (PIC) which is needed
6026 for linking it into DSOs.
6027 [Ralf S. Engelschall]
6029 *) Remarkably, export ciphers were totally broken and no-one had noticed!
6033 *) Cleaned up the LICENSE document: The official contact for any license
6034 questions now is the OpenSSL core team under openssl-core@openssl.org.
6035 And add a paragraph about the dual-license situation to make sure people
6036 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
6037 to the OpenSSL toolkit.
6038 [Ralf S. Engelschall]
6040 *) General source tree makefile cleanups: Made `making xxx in yyy...'
6041 display consistent in the source tree and replaced `/bin/rm' by `rm'.
6042 Additonally cleaned up the `make links' target: Remove unnecessary
6043 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
6044 to speed processing and no longer clutter the display with confusing
6045 stuff. Instead only the actually done links are displayed.
6046 [Ralf S. Engelschall]
6048 *) Permit null encryption ciphersuites, used for authentication only. It used
6049 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
6050 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
6054 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
6055 signed attributes when verifying signatures (this would break them),
6056 the detached data encoding was wrong and public keys obtained using
6057 X509_get_pubkey() weren't freed.
6060 *) Add text documentation for the BUFFER functions. Also added a work around
6061 to a Win95 console bug. This was triggered by the password read stuff: the
6062 last character typed gets carried over to the next fread(). If you were
6063 generating a new cert request using 'req' for example then the last
6064 character of the passphrase would be CR which would then enter the first
6068 *) Added the new `Includes OpenSSL Cryptography Software' button as
6069 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
6070 button and can be used by applications based on OpenSSL to show the
6071 relationship to the OpenSSL project.
6072 [Ralf S. Engelschall]
6074 *) Remove confusing variables in function signatures in files
6075 ssl/ssl_lib.c and ssl/ssl.h.
6076 [Lennart Bong <lob@kulthea.stacken.kth.se>]
6078 *) Don't install bss_file.c under PREFIX/include/
6079 [Lennart Bong <lob@kulthea.stacken.kth.se>]
6081 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
6082 functions that return function pointers and has support for NT specific
6083 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
6084 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
6085 unsigned to signed types: this was killing the Win32 compile.
6088 *) Add new certificate file to stack functions,
6089 SSL_add_dir_cert_subjects_to_stack() and
6090 SSL_add_file_cert_subjects_to_stack(). These largely supplant
6091 SSL_load_client_CA_file(), and can be used to add multiple certs easily
6092 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
6093 This means that Apache-SSL and similar packages don't have to mess around
6094 to add as many CAs as they want to the preferred list.
6097 *) Experiment with doxygen documentation. Currently only partially applied to
6099 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
6100 openssl.doxy as the configuration file.
6103 *) Get rid of remaining C++-style comments which strict C compilers hate.
6104 [Ralf S. Engelschall, pointed out by Carlos Amengual]
6106 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
6107 compiled in by default: it has problems with large keys.
6110 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
6111 DH private keys and/or callback functions which directly correspond to
6112 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
6113 is needed for applications which have to configure certificates on a
6114 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
6116 For the RSA certificate situation is makes no difference, but
6117 for the DSA certificate situation this fixes the "no shared cipher"
6118 problem where the OpenSSL cipher selection procedure failed because the
6119 temporary keys were not overtaken from the context and the API provided
6120 no way to reconfigure them.
6121 The new functions now let applications reconfigure the stuff and they
6122 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
6123 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
6124 non-public-API function ssl_cert_instantiate() is used as a helper
6125 function and also to reduce code redundancy inside ssl_rsa.c.
6126 [Ralf S. Engelschall]
6128 *) Move s_server -dcert and -dkey options out of the undocumented feature
6129 area because they are useful for the DSA situation and should be
6130 recognized by the users.
6131 [Ralf S. Engelschall]
6133 *) Fix the cipher decision scheme for export ciphers: the export bits are
6134 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
6135 SSL_EXP_MASK. So, the original variable has to be used instead of the
6136 already masked variable.
6137 [Richard Levitte <levitte@stacken.kth.se>]
6139 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
6140 [Richard Levitte <levitte@stacken.kth.se>]
6142 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
6143 from `int' to `unsigned int' because it's a length and initialized by
6144 EVP_DigestFinal() which expects an `unsigned int *'.
6145 [Richard Levitte <levitte@stacken.kth.se>]
6147 *) Don't hard-code path to Perl interpreter on shebang line of Configure
6148 script. Instead use the usual Shell->Perl transition trick.
6149 [Ralf S. Engelschall]
6151 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
6152 (in addition to RSA certificates) to match the behaviour of `openssl dsa
6153 -noout -modulus' as it's already the case for `openssl rsa -noout
6154 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
6155 currently the public key is printed (a decision which was already done by
6156 `openssl dsa -modulus' in the past) which serves a similar purpose.
6157 Additionally the NO_RSA no longer completely removes the whole -modulus
6158 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
6160 [Ralf S. Engelschall]
6162 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
6163 BIO. See the source (crypto/evp/bio_ok.c) for more info.
6164 [Arne Ansper <arne@ats.cyber.ee>]
6166 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
6167 to be added. Now both 'req' and 'ca' can use new objects defined in the
6171 *) Add cool BIO that does syslog (or event log on NT).
6172 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
6174 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
6175 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
6176 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
6177 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
6180 *) Add preliminary config info for new extension code.
6183 *) Make RSA_NO_PADDING really use no padding.
6184 [Ulf Moeller <ulf@fitug.de>]
6186 *) Generate errors when private/public key check is done.
6189 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
6190 for some CRL extensions and new objects added.
6193 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
6194 key usage extension and fuller support for authority key id.
6197 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
6198 padding method for RSA, which is recommended for new applications in PKCS
6199 #1 v2.0 (RFC 2437, October 1998).
6200 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
6201 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
6202 against Bleichbacher's attack on RSA.
6203 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
6206 *) Updates to the new SSL compression code
6207 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
6209 *) Fix so that the version number in the master secret, when passed
6210 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
6211 (because the server will not accept higher), that the version number
6212 is 0x03,0x01, not 0x03,0x00
6213 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
6215 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
6216 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
6217 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
6220 *) Support for RAW extensions where an arbitrary extension can be
6221 created by including its DER encoding. See apps/openssl.cnf for
6225 *) Make sure latest Perl versions don't interpret some generated C array
6226 code as Perl array code in the crypto/err/err_genc.pl script.
6227 [Lars Weber <3weber@informatik.uni-hamburg.de>]
6229 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
6230 not many people have the assembler. Various Win32 compilation fixes and
6231 update to the INSTALL.W32 file with (hopefully) more accurate Win32
6235 *) Modify configure script 'Configure' to automatically create crypto/date.h
6236 file under Win32 and also build pem.h from pem.org. New script
6237 util/mkfiles.pl to create the MINFO file on environments that can't do a
6238 'make files': perl util/mkfiles.pl >MINFO should work.
6241 *) Major rework of DES function declarations, in the pursuit of correctness
6242 and purity. As a result, many evil casts evaporated, and some weirdness,
6243 too. You may find this causes warnings in your code. Zapping your evil
6244 casts will probably fix them. Mostly.
6247 *) Fix for a typo in asn1.h. Bug fix to object creation script
6248 obj_dat.pl. It considered a zero in an object definition to mean
6249 "end of object": none of the objects in objects.h have any zeros
6250 so it wasn't spotted.
6251 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
6253 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
6254 Masking (CBCM). In the absence of test vectors, the best I have been able
6255 to do is check that the decrypt undoes the encrypt, so far. Send me test
6256 vectors if you have them.
6259 *) Correct calculation of key length for export ciphers (too much space was
6260 allocated for null ciphers). This has not been tested!
6263 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
6264 message is now correct (it understands "crypto" and "ssl" on its
6265 command line). There is also now an "update" option. This will update
6266 the util/ssleay.num and util/libeay.num files with any new functions.
6268 perl util/mkdef.pl crypto ssl update
6269 it will update them.
6272 *) Overhauled the Perl interface (perl/*):
6273 - ported BN stuff to OpenSSL's different BN library
6274 - made the perl/ source tree CVS-aware
6275 - renamed the package from SSLeay to OpenSSL (the files still contain
6276 their history because I've copied them in the repository)
6277 - removed obsolete files (the test scripts will be replaced
6278 by better Test::Harness variants in the future)
6279 [Ralf S. Engelschall]
6281 *) First cut for a very conservative source tree cleanup:
6282 1. merge various obsolete readme texts into doc/ssleay.txt
6283 where we collect the old documents and readme texts.
6284 2. remove the first part of files where I'm already sure that we no
6285 longer need them because of three reasons: either they are just temporary
6286 files which were left by Eric or they are preserved original files where
6287 I've verified that the diff is also available in the CVS via "cvs diff
6288 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
6289 the crypto/md/ stuff).
6290 [Ralf S. Engelschall]
6292 *) More extension code. Incomplete support for subject and issuer alt
6293 name, issuer and authority key id. Change the i2v function parameters
6294 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
6295 what that's for :-) Fix to ASN1 macro which messed up
6296 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
6299 *) Preliminary support for ENUMERATED type. This is largely copied from the
6303 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
6304 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
6306 *) Make sure `make rehash' target really finds the `openssl' program.
6307 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
6309 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
6310 like to hear about it if this slows down other processors.
6313 *) Add CygWin32 platform information to Configure script.
6314 [Alan Batie <batie@aahz.jf.intel.com>]
6316 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
6317 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
6319 *) New program nseq to manipulate netscape certificate sequences
6322 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
6326 *) Fixes to BN code. Previously the default was to define BN_RECURSION
6327 but the BN code had some problems that would cause failures when
6328 doing certificate verification and some other functions.
6329 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
6331 *) Add ASN1 and PEM code to support netscape certificate sequences.
6334 *) Add ASN1 and PEM code to support netscape certificate sequences.
6337 *) Add several PKIX and private extended key usage OIDs.
6340 *) Modify the 'ca' program to handle the new extension code. Modify
6341 openssl.cnf for new extension format, add comments.
6344 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
6345 and add a sample to openssl.cnf so req -x509 now adds appropriate
6349 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
6350 error code, add initial support to X509_print() and x509 application.
6353 *) Takes a deep breath and start addding X509 V3 extension support code. Add
6354 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
6355 stuff is currently isolated and isn't even compiled yet.
6358 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
6359 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
6360 Removed the versions check from X509 routines when loading extensions:
6361 this allows certain broken certificates that don't set the version
6362 properly to be processed.
6365 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
6366 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
6367 can still be regenerated with "make depend".
6370 *) Spelling mistake in C version of CAST-128.
6371 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
6373 *) Changes to the error generation code. The perl script err-code.pl
6374 now reads in the old error codes and retains the old numbers, only
6375 adding new ones if necessary. It also only changes the .err files if new
6376 codes are added. The makefiles have been modified to only insert errors
6377 when needed (to avoid needlessly modifying header files). This is done
6378 by only inserting errors if the .err file is newer than the auto generated
6379 C file. To rebuild all the error codes from scratch (the old behaviour)
6380 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
6381 or delete all the .err files.
6384 *) CAST-128 was incorrectly implemented for short keys. The C version has
6385 been fixed, but is untested. The assembler versions are also fixed, but
6386 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
6387 to regenerate it if needed.
6388 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
6389 Hagino <itojun@kame.net>]
6391 *) File was opened incorrectly in randfile.c.
6392 [Ulf Möller <ulf@fitug.de>]
6394 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
6395 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
6396 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
6397 al: it's just almost always a UTCTime. Note this patch adds new error
6398 codes so do a "make errors" if there are problems.
6401 *) Correct Linux 1 recognition in config.
6402 [Ulf Möller <ulf@fitug.de>]
6404 *) Remove pointless MD5 hash when using DSA keys in ca.
6405 [Anonymous <nobody@replay.com>]
6407 *) Generate an error if given an empty string as a cert directory. Also
6408 generate an error if handed NULL (previously returned 0 to indicate an
6409 error, but didn't set one).
6410 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
6412 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
6415 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
6416 parameters. This was causing a warning which killed off the Win32 compile.
6419 *) Remove C++ style comments from crypto/bn/bn_local.h.
6420 [Neil Costigan <neil.costigan@celocom.com>]
6422 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
6423 based on a text string, looking up short and long names and finally
6424 "dot" format. The "dot" format stuff didn't work. Added new function
6425 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
6426 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
6427 OID is not part of the table.
6430 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
6431 X509_LOOKUP_by_alias().
6434 *) Sort openssl functions by name.
6437 *) Get the gendsa program working (hopefully) and add it to app list. Remove
6438 encryption from sample DSA keys (in case anyone is interested the password
6442 *) Make _all_ *_free functions accept a NULL pointer.
6443 [Frans Heymans <fheymans@isaserver.be>]
6445 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
6447 [Anonymous <nobody@replay.com>]
6449 *) s_server should send the CAfile as acceptable CAs, not its own cert.
6450 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
6452 *) Don't blow it for numeric -newkey arguments to apps/req.
6453 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
6455 *) Temp key "for export" tests were wrong in s3_srvr.c.
6456 [Anonymous <nobody@replay.com>]
6458 *) Add prototype for temp key callback functions
6459 SSL_CTX_set_tmp_{rsa,dh}_callback().
6462 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
6463 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
6466 *) X509_name_add_entry() freed the wrong thing after an error.
6467 [Arne Ansper <arne@ats.cyber.ee>]
6469 *) rsa_eay.c would attempt to free a NULL context.
6470 [Arne Ansper <arne@ats.cyber.ee>]
6472 *) BIO_s_socket() had a broken should_retry() on Windoze.
6473 [Arne Ansper <arne@ats.cyber.ee>]
6475 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
6476 [Arne Ansper <arne@ats.cyber.ee>]
6478 *) Make sure the already existing X509_STORE->depth variable is initialized
6479 in X509_STORE_new(), but document the fact that this variable is still
6480 unused in the certificate verification process.
6481 [Ralf S. Engelschall]
6483 *) Fix the various library and apps files to free up pkeys obtained from
6484 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
6487 *) Fix reference counting in X509_PUBKEY_get(). This makes
6488 demos/maurice/example2.c work, amongst others, probably.
6489 [Steve Henson and Ben Laurie]
6491 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
6492 `openssl' and second, the shortcut symlinks for the `openssl <command>'
6493 are no longer created. This way we have a single and consistent command
6494 line interface `openssl <command>', similar to `cvs <command>'.
6495 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
6497 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
6498 BIT STRING wrapper always have zero unused bits.
6501 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
6504 *) Make the top-level INSTALL documentation easier to understand.
6507 *) Makefiles updated to exit if an error occurs in a sub-directory
6508 make (including if user presses ^C) [Paul Sutton]
6510 *) Make Montgomery context stuff explicit in RSA data structure.
6513 *) Fix build order of pem and err to allow for generated pem.h.
6516 *) Fix renumbering bug in X509_NAME_delete_entry().
6519 *) Enhanced the err-ins.pl script so it makes the error library number
6520 global and can add a library name. This is needed for external ASN1 and
6521 other error libraries.
6524 *) Fixed sk_insert which never worked properly.
6527 *) Fix ASN1 macros so they can handle indefinite length construted
6528 EXPLICIT tags. Some non standard certificates use these: they can now
6532 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
6533 into a single doc/ssleay.txt bundle. This way the information is still
6534 preserved but no longer messes up this directory. Now it's new room for
6535 the new set of documenation files.
6536 [Ralf S. Engelschall]
6538 *) SETs were incorrectly DER encoded. This was a major pain, because they
6539 shared code with SEQUENCEs, which aren't coded the same. This means that
6540 almost everything to do with SETs or SEQUENCEs has either changed name or
6541 number of arguments.
6542 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
6544 *) Fix test data to work with the above.
6547 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
6548 was already fixed by Eric for 0.9.1 it seems.
6549 [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
6551 *) Autodetect FreeBSD3.
6554 *) Fix various bugs in Configure. This affects the following platforms:
6558 unixware-2.0-pentium
6562 *) Eliminate generated files from CVS. Reorder tests to regenerate files
6563 before they are needed.
6566 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
6570 Changes between 0.9.1b and 0.9.1c [23-Dec-1998]
6572 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
6573 changed SSLeay to OpenSSL in version strings.
6574 [Ralf S. Engelschall]
6576 *) Some fixups to the top-level documents.
6579 *) Fixed the nasty bug where rsaref.h was not found under compile-time
6580 because the symlink to include/ was missing.
6581 [Ralf S. Engelschall]
6583 *) Incorporated the popular no-RSA/DSA-only patches
6584 which allow to compile a RSA-free SSLeay.
6585 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
6587 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
6588 when "ssleay" is still not found.
6589 [Ralf S. Engelschall]
6591 *) Added more platforms to Configure: Cray T3E, HPUX 11,
6592 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
6594 *) Updated the README file.
6595 [Ralf S. Engelschall]
6597 *) Added various .cvsignore files in the CVS repository subdirs
6598 to make a "cvs update" really silent.
6599 [Ralf S. Engelschall]
6601 *) Recompiled the error-definition header files and added
6602 missing symbols to the Win32 linker tables.
6603 [Ralf S. Engelschall]
6605 *) Cleaned up the top-level documents;
6606 o new files: CHANGES and LICENSE
6607 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
6608 o merged COPYRIGHT into LICENSE
6609 o removed obsolete TODO file
6610 o renamed MICROSOFT to INSTALL.W32
6611 [Ralf S. Engelschall]
6613 *) Removed dummy files from the 0.9.1b source tree:
6614 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
6615 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f

6618 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
6619 [Ralf S. Engelschall]
6621 *) Added various platform portability fixes.
6624 *) The Genesis of the OpenSSL rpject:
6625 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
6626 Young and Tim J. Hudson created while they were working for C2Net until
6628 [The OpenSSL Project]
6631 Changes between 0.9.0b and 0.9.1b [not released]
6633 *) Updated a few CA certificates under certs/
6636 *) Changed some BIGNUM api stuff.
6639 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
6640 DGUX x86, Linux Alpha, etc.
6643 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
6644 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
6648 *) Add -strparse option to asn1pars program which parses nested
6650 [Dr Stephen Henson <shenson@bigfoot.com>]
6652 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
6655 *) DSA fix for "ca" program.
6658 *) Added "-genkey" option to "dsaparam" program.
6661 *) Added RIPE MD160 (rmd160) message digest.
6664 *) Added -a (all) option to "ssleay version" command.
6667 *) Added PLATFORM define which is the id given to Configure.
6670 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
6673 *) Extended the ASN.1 parser routines.
6676 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
6679 *) Added a BN_CTX to the BN library.
6682 *) Fixed the weak key values in DES library
6685 *) Changed API in EVP library for cipher aliases.
6688 *) Added support for RC2/64bit cipher.
6691 *) Converted the lhash library to the crypto/mem.c functions.
6694 *) Added more recognized ASN.1 object ids.
6697 *) Added more RSA padding checks for SSL/TLS.
6700 *) Added BIO proxy/filter functionality.
6703 *) Added extra_certs to SSL_CTX which can be used
6704 send extra CA certificates to the client in the CA cert chain sending
6705 process. It can be configured with SSL_CTX_add_extra_chain_cert().
6708 *) Now Fortezza is denied in the authentication phase because
6709 this is key exchange mechanism is not supported by SSLeay at all.
6712 *) Additional PKCS1 checks.
6715 *) Support the string "TLSv1" for all TLS v1 ciphers.
6718 *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
6719 ex_data index of the SSL context in the X509_STORE_CTX ex_data.
6722 *) Fixed a few memory leaks.
6725 *) Fixed various code and comment typos.
6728 *) A minor bug in ssl/s3_clnt.c where there would always be 4 0
6729 bytes sent in the client random.
