5 Changes between 0.9.7e and 0.9.8 [xx XXX xxxx]
7 *) Change ./Configure so that certain algorithms can be disabled by default.
8 The new counterpiece to "no-xxx" is "enable-xxx".
10 The patented RC5 and MDC2 algorithms will now be disabled unless
11 "enable-rc5" and "enable-mdc2", respectively, are specified.
13 (IDEA remains enabled despite being patented. This is because IDEA
14 is frequently required for interoperability, and there is no license
15 fee for non-commercial use. As before, "no-idea" can be used to
16 avoid this algorithm.)
20 *) Add processing of proxy certificates (see RFC 3820). This work was
21 sponsored by KTH (The Royal Institute of Technology in Stockholm) and
22 EGEE (Enabling Grids for E-science in Europe).
25 *) RC4 performance overhaul on modern architectures/implementations, such
26 as Intel P4, IA-64 and AMD64.
29 *) New utility extract-section.pl. This can be used specify an alternative
30 section number in a pod file instead of having to treat each file as
31 a separate case in Makefile. This can be done by adding two lines to the
34 =for comment openssl_section:XXX
36 The blank line is mandatory.
40 *) New arguments -certform, -keyform and -pass for s_client and s_server
41 to allow alternative format key and certificate files and passphrase
45 *) New structure X509_VERIFY_PARAM which combines current verify parameters,
46 update associated structures and add various utility functions.
48 Add new policy related verify parameters, include policy checking in
49 standard verify code. Enhance 'smime' application with extra parameters
50 to support policy checking and print out.
53 *) Add a new engine to support VIA PadLock ACE extensions in the VIA C3
54 Nehemiah processors. These extensions support AES encryption in hardware
55 as well as RNG (though RNG support is currently disabled).
56 [Michal Ludvig <michal@logix.cz>, with help from Andy Polyakov]
58 *) Deprecate BN_[get|set]_params() functions (they were ignored internally).
61 *) New FIPS 180-2 algorithms, SHA-224/-256/-384/-512 are implemented.
62 [Andy Polyakov and a number of other people]
64 *) Improved PowerPC platform support. Most notably BIGNUM assembler
65 implementation contributed by IBM.
66 [Suresh Chari, Peter Waltenberg, Andy Polyakov]
68 *) The new 'RSA_generate_key_ex' function now takes a BIGNUM for the public
69 exponent rather than 'unsigned long'. There is a corresponding change to
70 the new 'rsa_keygen' element of the RSA_METHOD structure.
71 [Jelte Jansen, Geoff Thorpe]
73 *) Functionality for creating the initial serial number file is now
74 moved from CA.pl to the 'ca' utility with a new option -create_serial.
76 (Before OpenSSL 0.9.7e, CA.pl used to initialize the serial
77 number file to 1, which is bound to cause problems. To avoid
78 the problems while respecting compatibility between different 0.9.7
79 patchlevels, 0.9.7e employed 'openssl x509 -next_serial' in
80 CA.pl for serial number initialization. With the new release 0.9.8,
81 we can fix the problem directly in the 'ca' utility.)
84 *) Reduced header interdepencies by declaring more opaque objects in
85 ossl_typ.h. As a consequence, including some headers (eg. engine.h) will
86 give fewer recursive includes, which could break lazy source code - so
87 this change is covered by the OPENSSL_NO_DEPRECATED symbol. As always,
88 developers should define this symbol when building and using openssl to
89 ensure they track the recommended behaviour, interfaces, [etc], but
90 backwards-compatible behaviour prevails when this isn't defined.
93 *) New function X509_POLICY_NODE_print() which prints out policy nodes.
96 *) Add new EVP function EVP_CIPHER_CTX_rand_key and associated functionality.
97 This will generate a random key of the appropriate length based on the
98 cipher context. The EVP_CIPHER can provide its own random key generation
99 routine to support keys of a specific form. This is used in the des and
100 3des routines to generate a key of the correct parity. Update S/MIME
101 code to use new functions and hence generate correct parity DES keys.
102 Add EVP_CHECK_DES_KEY #define to return an error if the key is not
103 valid (weak or incorrect parity).
106 *) Add a local set of CRLs that can be used by X509_verify_cert() as well
107 as looking them up. This is useful when the verified structure may contain
108 CRLs, for example PKCS#7 signedData. Modify PKCS7_verify() to use any CRLs
109 present unless the new PKCS7_NO_CRL flag is asserted.
112 *) Extend ASN1 oid configuration module. It now additionally accepts the
115 shortName = some long name, 1.2.3.4
118 *) Reimplemented the BN_CTX implementation. There is now no more static
119 limitation on the number of variables it can handle nor the depth of the
120 "stack" handling for BN_CTX_start()/BN_CTX_end() pairs. The stack
121 information can now expand as required, and rather than having a single
122 static array of bignums, BN_CTX now uses a linked-list of such arrays
123 allowing it to expand on demand whilst maintaining the usefulness of
127 *) Add a missing BN_CTX parameter to the 'rsa_mod_exp' callback in RSA_METHOD
128 to allow all RSA operations to function using a single BN_CTX.
131 *) Preliminary support for certificate policy evaluation and checking. This
132 is initially intended to pass the tests outlined in "Conformance Testing
133 of Relying Party Client Certificate Path Processing Logic" v1.07.
136 *) bn_dup_expand() has been deprecated, it was introduced in 0.9.7 and
137 remained unused and not that useful. A variety of other little bignum
138 tweaks and fixes have also been made continuing on from the audit (see
142 *) Constify all or almost all d2i, c2i, s2i and r2i functions, along with
143 associated ASN1, EVP and SSL functions and old ASN1 macros.
146 *) BN_zero() only needs to set 'top' and 'neg' to zero for correct results,
147 and this should never fail. So the return value from the use of
148 BN_set_word() (which can fail due to needless expansion) is now deprecated;
149 if OPENSSL_NO_DEPRECATED is defined, BN_zero() is a void macro.
152 *) BN_CTX_get() should return zero-valued bignums, providing the same
153 initialised value as BN_new().
154 [Geoff Thorpe, suggested by Ulf Möller]
156 *) Support for inhibitAnyPolicy certificate extension.
159 *) An audit of the BIGNUM code is underway, for which debugging code is
160 enabled when BN_DEBUG is defined. This makes stricter enforcements on what
161 is considered valid when processing BIGNUMs, and causes execution to
162 assert() when a problem is discovered. If BN_DEBUG_RAND is defined,
163 further steps are taken to deliberately pollute unused data in BIGNUM
164 structures to try and expose faulty code further on. For now, openssl will
165 (in its default mode of operation) continue to tolerate the inconsistent
166 forms that it has tolerated in the past, but authors and packagers should
167 consider trying openssl and their own applications when compiled with
168 these debugging symbols defined. It will help highlight potential bugs in
169 their own code, and will improve the test coverage for OpenSSL itself. At
170 some point, these tighter rules will become openssl's default to improve
171 maintainability, though the assert()s and other overheads will remain only
172 in debugging configurations. See bn.h for more details.
173 [Geoff Thorpe, Nils Larsch, Ulf Möller]
175 *) BN_CTX_init() has been deprecated, as BN_CTX is an opaque structure
176 that can only be obtained through BN_CTX_new() (which implicitly
177 initialises it). The presence of this function only made it possible
178 to overwrite an existing structure (and cause memory leaks).
181 *) Because of the callback-based approach for implementing LHASH as a
182 template type, lh_insert() adds opaque objects to hash-tables and
183 lh_doall() or lh_doall_arg() are typically used with a destructor callback
184 to clean up those corresponding objects before destroying the hash table
185 (and losing the object pointers). So some over-zealous constifications in
186 LHASH have been relaxed so that lh_insert() does not take (nor store) the
187 objects as "const" and the lh_doall[_arg] callback wrappers are not
188 prototyped to have "const" restrictions on the object pointers they are
189 given (and so aren't required to cast them away any more).
192 *) The tmdiff.h API was so ugly and minimal that our own timing utility
193 (speed) prefers to use its own implementation. The two implementations
194 haven't been consolidated as yet (volunteers?) but the tmdiff API has had
195 its object type properly exposed (MS_TM) instead of casting to/from "char
196 *". This may still change yet if someone realises MS_TM and "ms_time_***"
197 aren't necessarily the greatest nomenclatures - but this is what was used
198 internally to the implementation so I've used that for now.
201 *) Ensure that deprecated functions do not get compiled when
202 OPENSSL_NO_DEPRECATED is defined. Some "openssl" subcommands and a few of
203 the self-tests were still using deprecated key-generation functions so
204 these have been updated also.
207 *) Reorganise PKCS#7 code to separate the digest location functionality
208 into PKCS7_find_digest(), digest addtion into PKCS7_bio_add_digest().
209 New function PKCS7_set_digest() to set the digest type for PKCS#7
210 digestedData type. Add additional code to correctly generate the
211 digestedData type and add support for this type in PKCS7 initialization
215 *) New function PKCS7_set0_type_other() this initializes a PKCS7
216 structure of type "other".
219 *) Fix prime generation loop in crypto/bn/bn_prime.pl by making
220 sure the loop does correctly stop and breaking ("division by zero")
221 modulus operations are not performed. The (pre-generated) prime
222 table crypto/bn/bn_prime.h was already correct, but it could not be
223 re-generated on some platforms because of the "division by zero"
224 situation in the script.
225 [Ralf S. Engelschall]
227 *) Update support for ECC-based TLS ciphersuites according to
228 draft-ietf-tls-ecc-03.txt: the KDF1 key derivation function with
229 SHA-1 now is only used for "small" curves (where the
230 representation of a field element takes up to 24 bytes); for
231 larger curves, the field element resulting from ECDH is directly
232 used as premaster secret.
233 [Douglas Stebila (Sun Microsystems Laboratories)]
235 *) Add code for kP+lQ timings to crypto/ec/ectest.c, and add SEC2
236 curve secp160r1 to the tests.
237 [Douglas Stebila (Sun Microsystems Laboratories)]
239 *) Add the possibility to load symbols globally with DSO.
240 [Götz Babin-Ebell <babin-ebell@trustcenter.de> via Richard Levitte]
242 *) Add the functions ERR_set_mark() and ERR_pop_to_mark() for better
243 control of the error stack.
246 *) Add support for STORE in ENGINE.
249 *) Add the STORE type. The intention is to provide a common interface
250 to certificate and key stores, be they simple file-based stores, or
251 HSM-type store, or LDAP stores, or...
252 NOTE: The code is currently UNTESTED and isn't really used anywhere.
255 *) Add a generic structure called OPENSSL_ITEM. This can be used to
256 pass a list of arguments to any function as well as provide a way
257 for a function to pass data back to the caller.
260 *) Add the functions BUF_strndup() and BUF_memdup(). BUF_strndup()
261 works like BUF_strdup() but can be used to duplicate a portion of
262 a string. The copy gets NUL-terminated. BUF_memdup() duplicates
266 *) Add the function sk_find_ex() which works like sk_find(), but will
267 return an index to an element even if an exact match couldn't be
268 found. The index is guaranteed to point at the element where the
269 searched-for key would be inserted to preserve sorting order.
272 *) Add the function OBJ_bsearch_ex() which works like OBJ_bsearch() but
273 takes an extra flags argument for optional functionality. Currently,
274 the following flags are defined:
276 OBJ_BSEARCH_VALUE_ON_NOMATCH
277 This one gets OBJ_bsearch_ex() to return a pointer to the first
278 element where the comparing function returns a negative or zero
281 OBJ_BSEARCH_FIRST_VALUE_ON_MATCH
282 This one gets OBJ_bsearch_ex() to return a pointer to the first
283 element where the comparing function returns zero. This is useful
284 if there are more than one element where the comparing function
288 *) Make it possible to create self-signed certificates with 'openssl ca'
289 in such a way that the self-signed certificate becomes part of the
290 CA database and uses the same mechanisms for serial number generation
291 as all other certificate signing. The new flag '-selfsign' enables
292 this functionality. Adapt CA.sh and CA.pl.in.
295 *) Add functionality to check the public key of a certificate request
296 against a given private. This is useful to check that a certificate
297 request can be signed by that key (self-signing).
300 *) Make it possible to have multiple active certificates with the same
301 subject in the CA index file. This is done only if the keyword
302 'unique_subject' is set to 'no' in the main CA section (default
303 if 'CA_default') of the configuration file. The value is saved
304 with the database itself in a separate index attribute file,
305 named like the index file with '.attr' appended to the name.
308 *) Generate muti valued AVAs using '+' notation in config files for
312 *) Support for nameConstraints certificate extension.
315 *) Support for policyConstraints certificate extension.
318 *) Support for policyMappings certificate extension.
321 *) Make sure the default DSA_METHOD implementation only uses its
322 dsa_mod_exp() and/or bn_mod_exp() handlers if they are non-NULL,
323 and change its own handlers to be NULL so as to remove unnecessary
324 indirection. This lets alternative implementations fallback to the
325 default implementation more easily.
328 *) Support for directoryName in GeneralName related extensions
332 *) Make it possible to link applications using Makefile.shared.
333 Make that possible even when linking against static libraries!
336 *) Support for single pass processing for S/MIME signing. This now
337 means that S/MIME signing can be done from a pipe, in addition
338 cleartext signing (multipart/signed type) is effectively streaming
339 and the signed data does not need to be all held in memory.
341 This is done with a new flag PKCS7_STREAM. When this flag is set
342 PKCS7_sign() only initializes the PKCS7 structure and the actual signing
343 is done after the data is output (and digests calculated) in
347 *) Add full support for -rpath/-R, both in shared libraries and
348 applications, at least on the platforms where it's known how
352 *) In crypto/ec/ec_mult.c, implement fast point multiplication with
353 precomputation, based on wNAF splitting: EC_GROUP_precompute_mult()
354 will now compute a table of multiples of the generator that
355 makes subsequent invocations of EC_POINTs_mul() or EC_POINT_mul()
356 faster (notably in the case of a single point multiplication,
358 [Nils Larsch, Bodo Moeller]
360 *) IPv6 support for certificate extensions. The various extensions
361 which use the IP:a.b.c.d can now take IPv6 addresses using the
362 formats of RFC1884 2.2 . IPv6 addresses are now also displayed
366 *) Added an ENGINE that implements RSA by performing private key
367 exponentiations with the GMP library. The conversions to and from
368 GMP's mpz_t format aren't optimised nor are any montgomery forms
369 cached, and on x86 it appears OpenSSL's own performance has caught up.
370 However there are likely to be other architectures where GMP could
371 provide a boost. This ENGINE is not built in by default, but it can be
372 specified at Configure time and should be accompanied by the necessary
373 linker additions, eg;
374 ./config -DOPENSSL_USE_GMP -lgmp
377 *) "openssl engine" will not display ENGINE/DSO load failure errors when
378 testing availability of engines with "-t" - the old behaviour is
379 produced by increasing the feature's verbosity with "-tt".
382 *) ECDSA routines: under certain error conditions uninitialized BN objects
383 could be freed. Solution: make sure initialization is performed early
384 enough. (Reported and fix supplied by Nils Larsch <nla@trustcenter.de>
388 *) Key-generation can now be implemented in RSA_METHOD, DSA_METHOD
389 and DH_METHOD (eg. by ENGINE implementations) to override the normal
390 software implementations. For DSA and DH, parameter generation can
391 also be overriden by providing the appropriate method callbacks.
394 *) Change the "progress" mechanism used in key-generation and
395 primality testing to functions that take a new BN_GENCB pointer in
396 place of callback/argument pairs. The new API functions have "_ex"
397 postfixes and the older functions are reimplemented as wrappers for
398 the new ones. The OPENSSL_NO_DEPRECATED symbol can be used to hide
399 declarations of the old functions to help (graceful) attempts to
400 migrate to the new functions. Also, the new key-generation API
401 functions operate on a caller-supplied key-structure and return
402 success/failure rather than returning a key or NULL - this is to
403 help make "keygen" another member function of RSA_METHOD etc.
405 Example for using the new callback interface:
407 int (*my_callback)(int a, int b, BN_GENCB *cb) = ...;
411 BN_GENCB_set(&my_cb, my_callback, my_arg);
413 return BN_is_prime_ex(some_bignum, BN_prime_checks, NULL, &cb);
414 /* For the meaning of a, b in calls to my_callback(), see the
415 * documentation of the function that calls the callback.
416 * cb will point to my_cb; my_arg can be retrieved as cb->arg.
417 * my_callback should return 1 if it wants BN_is_prime_ex()
418 * to continue, or 0 to stop.
423 *) Change the ZLIB compression method to be stateful, and make it
424 available to TLS with the number defined in
425 draft-ietf-tls-compression-04.txt.
428 *) Add the ASN.1 structures and functions for CertificatePair, which
429 is defined as follows (according to X.509_4thEditionDraftV6.pdf):
431 CertificatePair ::= SEQUENCE {
432 forward [0] Certificate OPTIONAL,
433 reverse [1] Certificate OPTIONAL,
434 -- at least one of the pair shall be present -- }
436 Also implement the PEM functions to read and write certificate
437 pairs, and defined the PEM tag as "CERTIFICATE PAIR".
439 This needed to be defined, mostly for the sake of the LDAP
440 attribute crossCertificatePair, but may prove useful elsewhere as
444 *) Make it possible to inhibit symlinking of shared libraries in
445 Makefile.shared, for Cygwin's sake.
448 *) Extend the BIGNUM API by creating new macros that behave like
451 void BN_set_sign(BIGNUM *a, int neg);
452 int BN_get_sign(const BIGNUM *a);
454 and avoid the need to access 'a->neg' directly in applications.
455 [Nils Larsch <nla@trustcenter.de>]
457 *) Implement fast modular reduction for pseudo-Mersenne primes
458 used in NIST curves (crypto/bn/bn_nist.c, crypto/ec/ecp_nist.c).
459 EC_GROUP_new_curve_GFp() will now automatically use this
461 [Nils Larsch <nla@trustcenter.de>]
463 *) Add new lock type (CRYPTO_LOCK_BN).
466 *) Change the ENGINE framework to automatically load engines
467 dynamically from specific directories unless they could be
468 found to already be built in or loaded. Move all the
469 current engines except for the cryptodev one to a new
471 The engines in engines/ are built as shared libraries if
472 the "shared" options was given to ./Configure or ./config.
473 Otherwise, they are inserted in libcrypto.a.
474 /usr/local/ssl/engines is the default directory for dynamic
475 engines, but that can be overriden at configure time through
476 the usual use of --prefix and/or --openssldir, and at run
477 time with the environment variable OPENSSL_ENGINES.
478 [Geoff Thorpe and Richard Levitte]
480 *) Add Makefile.shared, a helper makefile to build shared
481 libraries. Addapt Makefile.org.
484 *) Add version info to Win32 DLLs.
485 [Peter 'Luna' Runestig" <peter@runestig.com>]
487 *) Add new 'medium level' PKCS#12 API. Certificates and keys
488 can be added using this API to created arbitrary PKCS#12
489 files while avoiding the low level API.
491 New options to PKCS12_create(), key or cert can be NULL and
492 will then be omitted from the output file. The encryption
493 algorithm NIDs can be set to -1 for no encryption, the mac
494 iteration count can be set to 0 to omit the mac.
496 Enhance pkcs12 utility by making the -nokeys and -nocerts
497 options work when creating a PKCS#12 file. New option -nomac
498 to omit the mac, NONE can be set for an encryption algorithm.
499 New code is modified to use the enhanced PKCS12_create()
500 instead of the low level API.
503 *) Extend ASN1 encoder to support indefinite length constructed
504 encoding. This can output sequences tags and octet strings in
505 this form. Modify pk7_asn1.c to support indefinite length
506 encoding. This is experimental and needs additional code to
507 be useful, such as an ASN1 bio and some enhanced streaming
510 Extend template encode functionality so that tagging is passed
511 down to the template encoder.
514 *) Let 'openssl req' fail if an argument to '-newkey' is not
515 recognized instead of using RSA as a default.
518 *) Add support for ECC-based ciphersuites from draft-ietf-tls-ecc-01.txt.
519 As these are not official, they are not included in "ALL";
520 the "ECCdraft" ciphersuite group alias can be used to select them.
521 [Vipul Gupta and Sumit Gupta (Sun Microsystems Laboratories)]
523 *) Add ECDH engine support.
524 [Nils Gura and Douglas Stebila (Sun Microsystems Laboratories)]
526 *) Add ECDH in new directory crypto/ecdh/.
527 [Douglas Stebila (Sun Microsystems Laboratories)]
529 *) Let BN_rand_range() abort with an error after 100 iterations
530 without success (which indicates a broken PRNG).
533 *) Change BN_mod_sqrt() so that it verifies that the input value
534 is really the square of the return value. (Previously,
535 BN_mod_sqrt would show GIGO behaviour.)
538 *) Add named elliptic curves over binary fields from X9.62, SECG,
539 and WAP/WTLS; add OIDs that were still missing.
541 [Sheueling Chang Shantz and Douglas Stebila
542 (Sun Microsystems Laboratories)]
544 *) Extend the EC library for elliptic curves over binary fields
545 (new files ec2_smpl.c, ec2_smpt.c, ec2_mult.c in crypto/ec/).
548 EC_GF2m_simple_method
552 EC_GROUP_new_curve_GF2m
553 EC_GROUP_set_curve_GF2m
554 EC_GROUP_get_curve_GF2m
555 EC_POINT_set_affine_coordinates_GF2m
556 EC_POINT_get_affine_coordinates_GF2m
557 EC_POINT_set_compressed_coordinates_GF2m
559 Point compression for binary fields is disabled by default for
560 patent reasons (compile with OPENSSL_EC_BIN_PT_COMP defined to
563 As binary polynomials are represented as BIGNUMs, various members
564 of the EC_GROUP and EC_POINT data structures can be shared
565 between the implementations for prime fields and binary fields;
566 the above ..._GF2m functions (except for EX_GROUP_new_curve_GF2m)
567 are essentially identical to their ..._GFp counterparts.
568 (For simplicity, the '..._GFp' prefix has been dropped from
569 various internal method names.)
571 An internal 'field_div' method (similar to 'field_mul' and
572 'field_sqr') has been added; this is used only for binary fields.
574 [Sheueling Chang Shantz and Douglas Stebila
575 (Sun Microsystems Laboratories)]
577 *) Optionally dispatch EC_POINT_mul(), EC_POINT_precompute_mult()
578 through methods ('mul', 'precompute_mult').
580 The generic implementations (now internally called 'ec_wNAF_mul'
581 and 'ec_wNAF_precomputed_mult') remain the default if these
582 methods are undefined.
584 [Sheueling Chang Shantz and Douglas Stebila
585 (Sun Microsystems Laboratories)]
587 *) New function EC_GROUP_get_degree, which is defined through
588 EC_METHOD. For curves over prime fields, this returns the bit
589 length of the modulus.
591 [Sheueling Chang Shantz and Douglas Stebila
592 (Sun Microsystems Laboratories)]
594 *) New functions EC_GROUP_dup, EC_POINT_dup.
595 (These simply call ..._new and ..._copy).
597 [Sheueling Chang Shantz and Douglas Stebila
598 (Sun Microsystems Laboratories)]
600 *) Add binary polynomial arithmetic software in crypto/bn/bn_gf2m.c.
601 Polynomials are represented as BIGNUMs (where the sign bit is not
602 used) in the following functions [macros]:
605 BN_GF2m_sub [= BN_GF2m_add]
606 BN_GF2m_mod [wrapper for BN_GF2m_mod_arr]
607 BN_GF2m_mod_mul [wrapper for BN_GF2m_mod_mul_arr]
608 BN_GF2m_mod_sqr [wrapper for BN_GF2m_mod_sqr_arr]
610 BN_GF2m_mod_exp [wrapper for BN_GF2m_mod_exp_arr]
611 BN_GF2m_mod_sqrt [wrapper for BN_GF2m_mod_sqrt_arr]
612 BN_GF2m_mod_solve_quad [wrapper for BN_GF2m_mod_solve_quad_arr]
613 BN_GF2m_cmp [= BN_ucmp]
615 (Note that only the 'mod' functions are actually for fields GF(2^m).
616 BN_GF2m_add() is misnomer, but this is for the sake of consistency.)
618 For some functions, an the irreducible polynomial defining a
619 field can be given as an 'unsigned int[]' with strictly
620 decreasing elements giving the indices of those bits that are set;
621 i.e., p[] represents the polynomial
622 f(t) = t^p[0] + t^p[1] + ... + t^p[k]
624 p[0] > p[1] > ... > p[k] = 0.
625 This applies to the following functions:
630 BN_GF2m_mod_inv_arr [wrapper for BN_GF2m_mod_inv]
631 BN_GF2m_mod_div_arr [wrapper for BN_GF2m_mod_div]
634 BN_GF2m_mod_solve_quad_arr
638 Conversion can be performed by the following functions:
643 bntest.c has additional tests for binary polynomial arithmetic.
645 Two implementations for BN_GF2m_mod_div() are available.
646 The default algorithm simply uses BN_GF2m_mod_inv() and
647 BN_GF2m_mod_mul(). The alternative algorithm is compiled in only
648 if OPENSSL_SUN_GF2M_DIV is defined (patent pending; read the
649 copyright notice in crypto/bn/bn_gf2m.c before enabling it).
651 [Sheueling Chang Shantz and Douglas Stebila
652 (Sun Microsystems Laboratories)]
654 *) Add new error code 'ERR_R_DISABLED' that can be used when some
655 functionality is disabled at compile-time.
656 [Douglas Stebila <douglas.stebila@sun.com>]
658 *) Change default behaviour of 'openssl asn1parse' so that more
659 information is visible when viewing, e.g., a certificate:
661 Modify asn1_parse2 (crypto/asn1/asn1_par.c) so that in non-'dump'
662 mode the content of non-printable OCTET STRINGs is output in a
663 style similar to INTEGERs, but with '[HEX DUMP]' prepended to
664 avoid the appearance of a printable string.
665 [Nils Larsch <nla@trustcenter.de>]
667 *) Add 'asn1_flag' and 'asn1_form' member to EC_GROUP with access
669 EC_GROUP_set_asn1_flag()
670 EC_GROUP_get_asn1_flag()
671 EC_GROUP_set_point_conversion_form()
672 EC_GROUP_get_point_conversion_form()
673 These control ASN1 encoding details:
674 - Curves (i.e., groups) are encoded explicitly unless asn1_flag
675 has been set to OPENSSL_EC_NAMED_CURVE.
676 - Points are encoded in uncompressed form by default; options for
677 asn1_for are as for point2oct, namely
678 POINT_CONVERSION_COMPRESSED
679 POINT_CONVERSION_UNCOMPRESSED
680 POINT_CONVERSION_HYBRID
682 Also add 'seed' and 'seed_len' members to EC_GROUP with access
686 EC_GROUP_get_seed_len()
687 This is used only for ASN1 purposes (so far).
688 [Nils Larsch <nla@trustcenter.de>]
690 *) Add 'field_type' member to EC_METHOD, which holds the NID
691 of the appropriate field type OID. The new function
692 EC_METHOD_get_field_type() returns this value.
693 [Nils Larsch <nla@trustcenter.de>]
700 providing useful interfaces to EC_POINT_point2oct() and
701 EC_POINT_oct2point().
702 [Nils Larsch <nla@trustcenter.de>]
704 *) Change internals of the EC library so that the functions
705 EC_GROUP_set_generator()
706 EC_GROUP_get_generator()
708 EC_GROUP_get_cofactor()
709 are implemented directly in crypto/ec/ec_lib.c and not dispatched
710 to methods, which would lead to unnecessary code duplication when
711 adding different types of curves.
712 [Nils Larsch <nla@trustcenter.de> with input by Bodo Moeller]
714 *) Implement compute_wNAF (crypto/ec/ec_mult.c) without BIGNUM
715 arithmetic, and such that modified wNAFs are generated
716 (which avoid length expansion in many cases).
719 *) Add a function EC_GROUP_check_discriminant() (defined via
720 EC_METHOD) that verifies that the curve discriminant is non-zero.
722 Add a function EC_GROUP_check() that makes some sanity tests
723 on a EC_GROUP, its generator and order. This includes
724 EC_GROUP_check_discriminant().
725 [Nils Larsch <nla@trustcenter.de>]
727 *) Add ECDSA in new directory crypto/ecdsa/.
729 Add applications 'openssl ecparam' and 'openssl ecdsa'
730 (these are based on 'openssl dsaparam' and 'openssl dsa').
732 ECDSA support is also included in various other files across the
733 library. Most notably,
734 - 'openssl req' now has a '-newkey ecdsa:file' option;
735 - EVP_PKCS82PKEY (crypto/evp/evp_pkey.c) now can handle ECDSA;
736 - X509_PUBKEY_get (crypto/asn1/x_pubkey.c) and
737 d2i_PublicKey (crypto/asn1/d2i_pu.c) have been modified to make
738 them suitable for ECDSA where domain parameters must be
739 extracted before the specific public key;
740 - ECDSA engine support has been added.
741 [Nils Larsch <nla@trustcenter.de>]
743 *) Include some named elliptic curves, and add OIDs from X9.62,
744 SECG, and WAP/WTLS. Each curve can be obtained from the new
746 EC_GROUP_new_by_nid(),
747 and the list of available named curves can be obtained with
748 EC_get_builtin_curves().
749 Also add a 'curve_name' member to EC_GROUP objects, which can be
753 [Nils Larsch <nla@trustcenter.de, Bodo Moeller]
755 *) Remove a few calls to bn_wexpand() in BN_sqr() (the one in there
756 was actually never needed) and in BN_mul(). The removal in BN_mul()
757 required a small change in bn_mul_part_recursive() and the addition
758 of the functions bn_cmp_part_words(), bn_sub_part_words() and
759 bn_add_part_words(), which do the same thing as bn_cmp_words(),
760 bn_sub_words() and bn_add_words() except they take arrays with
764 Changes between 0.9.7e and 0.9.7f [XX xxx XXXX]
766 *) Fix hang in EGD/PRNGD query when communication socket is closed
767 prematurely by EGD/PRNGD.
768 [Darren Tucker <dtucker@zip.com.au> via Lutz Jänicke, resolves #1014]
770 *) Prompt for pass phrases when appropriate for PKCS12 input format.
773 *) Add lots of checks for memory allocation failure, error codes to indicate
774 failure and freeing up memory if a failure occurs.
775 [Nauticus Networks SSL Team <openssl@nauticusnet.com>, Steve Henson]
777 *) Add new -passin argument to dgst.
780 *) Perform some character comparisons of different types in X509_NAME_cmp:
781 this is needed for some certificates that reencode DNs into UTF8Strings
782 (in violation of RFC3280) and can't or wont issue name rollover
786 *) Make an explicit check during certificate validation to see that
787 the CA setting in each certificate on the chain is correct. As a
788 side effect always do the following basic checks on extensions,
789 not just when there's an associated purpose to the check:
791 - if there is an unhandled critical extension (unless the user
792 has chosen to ignore this fault)
793 - if the path length has been exceeded (if one is set at all)
794 - that certain extensions fit the associated purpose (if one has
798 Changes between 0.9.7d and 0.9.7e [25 Oct 2004]
800 *) Avoid a race condition when CRLs are checked in a multi threaded
801 environment. This would happen due to the reordering of the revoked
802 entries during signature checking and serial number lookup. Now the
803 encoding is cached and the serial number sort performed under a lock.
804 Add new STACK function sk_is_sorted().
807 *) Add Delta CRL to the extension code.
810 *) Various fixes to s3_pkt.c so alerts are sent properly.
811 [David Holmes <d.holmes@f5.com>]
813 *) Reduce the chances of duplicate issuer name and serial numbers (in
814 violation of RFC3280) using the OpenSSL certificate creation utilities.
815 This is done by creating a random 64 bit value for the initial serial
816 number when a serial number file is created or when a self signed
817 certificate is created using 'openssl req -x509'. The initial serial
818 number file is created using 'openssl x509 -next_serial' in CA.pl
819 rather than being initialized to 1.
822 Changes between 0.9.7c and 0.9.7d [17 Mar 2004]
824 *) Fix null-pointer assignment in do_change_cipher_spec() revealed
825 by using the Codenomicon TLS Test Tool (CAN-2004-0079)
826 [Joe Orton, Steve Henson]
828 *) Fix flaw in SSL/TLS handshaking when using Kerberos ciphersuites
830 [Joe Orton, Steve Henson]
832 *) Make it possible to have multiple active certificates with the same
833 subject in the CA index file. This is done only if the keyword
834 'unique_subject' is set to 'no' in the main CA section (default
835 if 'CA_default') of the configuration file. The value is saved
836 with the database itself in a separate index attribute file,
837 named like the index file with '.attr' appended to the name.
840 *) X509 verify fixes. Disable broken certificate workarounds when
841 X509_V_FLAGS_X509_STRICT is set. Check CRL issuer has cRLSign set if
842 keyUsage extension present. Don't accept CRLs with unhandled critical
843 extensions: since verify currently doesn't process CRL extensions this
844 rejects a CRL with *any* critical extensions. Add new verify error codes
848 *) When creating an OCSP nonce use an OCTET STRING inside the extnValue.
849 A clarification of RFC2560 will require the use of OCTET STRINGs and
850 some implementations cannot handle the current raw format. Since OpenSSL
851 copies and compares OCSP nonces as opaque blobs without any attempt at
852 parsing them this should not create any compatibility issues.
855 *) New md flag EVP_MD_CTX_FLAG_REUSE this allows md_data to be reused when
856 calling EVP_MD_CTX_copy_ex() to avoid calling OPENSSL_malloc(). Without
857 this HMAC (and other) operations are several times slower than OpenSSL
861 *) Print out GeneralizedTime and UTCTime in ASN1_STRING_print_ex().
862 [Peter Sylvester <Peter.Sylvester@EdelWeb.fr>]
864 *) Use the correct content when signing type "other".
867 Changes between 0.9.7b and 0.9.7c [30 Sep 2003]
869 *) Fix various bugs revealed by running the NISCC test suite:
871 Stop out of bounds reads in the ASN1 code when presented with
872 invalid tags (CAN-2003-0543 and CAN-2003-0544).
874 Free up ASN1_TYPE correctly if ANY type is invalid (CAN-2003-0545).
876 If verify callback ignores invalid public key errors don't try to check
877 certificate signature with the NULL public key.
881 *) New -ignore_err option in ocsp application to stop the server
882 exiting on the first error in a request.
885 *) In ssl3_accept() (ssl/s3_srvr.c) only accept a client certificate
886 if the server requested one: as stated in TLS 1.0 and SSL 3.0
890 *) In ssl3_get_client_hello() (ssl/s3_srvr.c), tolerate additional
891 extra data after the compression methods not only for TLS 1.0
892 but also for SSL 3.0 (as required by the specification).
893 [Bodo Moeller; problem pointed out by Matthias Loepfe]
895 *) Change X509_certificate_type() to mark the key as exported/exportable
896 when it's 512 *bits* long, not 512 bytes.
899 *) Change AES_cbc_encrypt() so it outputs exact multiple of
900 blocks during encryption.
903 *) Various fixes to base64 BIO and non blocking I/O. On write
904 flushes were not handled properly if the BIO retried. On read
905 data was not being buffered properly and had various logic bugs.
906 This also affects blocking I/O when the data being decoded is a
910 *) Various S/MIME bugfixes and compatibility changes:
911 output correct application/pkcs7 MIME type if
912 PKCS7_NOOLDMIMETYPE is set. Tolerate some broken signatures.
913 Output CR+LF for EOL if PKCS7_CRLFEOL is set (this makes opening
914 of files as .eml work). Correctly handle very long lines in MIME
918 Changes between 0.9.7a and 0.9.7b [10 Apr 2003]
920 *) Countermeasure against the Klima-Pokorny-Rosa extension of
921 Bleichbacher's attack on PKCS #1 v1.5 padding: treat
922 a protocol version number mismatch like a decryption error
923 in ssl3_get_client_key_exchange (ssl/s3_srvr.c).
926 *) Turn on RSA blinding by default in the default implementation
927 to avoid a timing attack. Applications that don't want it can call
928 RSA_blinding_off() or use the new flag RSA_FLAG_NO_BLINDING.
929 They would be ill-advised to do so in most cases.
930 [Ben Laurie, Steve Henson, Geoff Thorpe, Bodo Moeller]
932 *) Change RSA blinding code so that it works when the PRNG is not
933 seeded (in this case, the secret RSA exponent is abused as
934 an unpredictable seed -- if it is not unpredictable, there
935 is no point in blinding anyway). Make RSA blinding thread-safe
936 by remembering the creator's thread ID in rsa->blinding and
937 having all other threads use local one-time blinding factors
938 (this requires more computation than sharing rsa->blinding, but
939 avoids excessive locking; and if an RSA object is not shared
940 between threads, blinding will still be very fast).
943 *) Fixed a typo bug that would cause ENGINE_set_default() to set an
944 ENGINE as defaults for all supported algorithms irrespective of
945 the 'flags' parameter. 'flags' is now honoured, so applications
946 should make sure they are passing it correctly.
949 *) Target "mingw" now allows native Windows code to be generated in
950 the Cygwin environment as well as with the MinGW compiler.
953 Changes between 0.9.7 and 0.9.7a [19 Feb 2003]
955 *) In ssl3_get_record (ssl/s3_pkt.c), minimize information leaked
956 via timing by performing a MAC computation even if incorrrect
957 block cipher padding has been found. This is a countermeasure
958 against active attacks where the attacker has to distinguish
959 between bad padding and a MAC verification error. (CAN-2003-0078)
961 [Bodo Moeller; problem pointed out by Brice Canvel (EPFL),
962 Alain Hiltgen (UBS), Serge Vaudenay (EPFL), and
963 Martin Vuagnoux (EPFL, Ilion)]
965 *) Make the no-err option work as intended. The intention with no-err
966 is not to have the whole error stack handling routines removed from
967 libcrypto, it's only intended to remove all the function name and
968 reason texts, thereby removing some of the footprint that may not
969 be interesting if those errors aren't displayed anyway.
971 NOTE: it's still possible for any application or module to have it's
972 own set of error texts inserted. The routines are there, just not
973 used by default when no-err is given.
976 *) Add support for FreeBSD on IA64.
977 [dirk.meyer@dinoex.sub.org via Richard Levitte, resolves #454]
979 *) Adjust DES_cbc_cksum() so it returns the same value as the MIT
980 Kerberos function mit_des_cbc_cksum(). Before this change,
981 the value returned by DES_cbc_cksum() was like the one from
982 mit_des_cbc_cksum(), except the bytes were swapped.
983 [Kevin Greaney <Kevin.Greaney@hp.com> and Richard Levitte]
985 *) Allow an application to disable the automatic SSL chain building.
986 Before this a rather primitive chain build was always performed in
987 ssl3_output_cert_chain(): an application had no way to send the
988 correct chain if the automatic operation produced an incorrect result.
990 Now the chain builder is disabled if either:
992 1. Extra certificates are added via SSL_CTX_add_extra_chain_cert().
994 2. The mode flag SSL_MODE_NO_AUTO_CHAIN is set.
996 The reasoning behind this is that an application would not want the
997 auto chain building to take place if extra chain certificates are
998 present and it might also want a means of sending no additional
999 certificates (for example the chain has two certificates and the
1003 *) Add the possibility to build without the ENGINE framework.
1004 [Steven Reddie <smr@essemer.com.au> via Richard Levitte]
1006 *) Under Win32 gmtime() can return NULL: check return value in
1007 OPENSSL_gmtime(). Add error code for case where gmtime() fails.
1010 *) DSA routines: under certain error conditions uninitialized BN objects
1011 could be freed. Solution: make sure initialization is performed early
1012 enough. (Reported and fix supplied by Ivan D Nestlerode <nestler@MIT.EDU>,
1013 Nils Larsch <nla@trustcenter.de> via PR#459)
1016 *) Another fix for SSLv2 session ID handling: the session ID was incorrectly
1017 checked on reconnect on the client side, therefore session resumption
1018 could still fail with a "ssl session id is different" error. This
1019 behaviour is masked when SSL_OP_ALL is used due to
1020 SSL_OP_MICROSOFT_SESS_ID_BUG being set.
1021 Behaviour observed by Crispin Flowerday <crispin@flowerday.cx> as
1022 followup to PR #377.
1025 *) IA-32 assembler support enhancements: unified ELF targets, support
1026 for SCO/Caldera platforms, fix for Cygwin shared build.
1029 *) Add support for FreeBSD on sparc64. As a consequence, support for
1030 FreeBSD on non-x86 processors is separate from x86 processors on
1031 the config script, much like the NetBSD support.
1032 [Richard Levitte & Kris Kennaway <kris@obsecurity.org>]
1034 Changes between 0.9.6h and 0.9.7 [31 Dec 2002]
1036 [NB: OpenSSL 0.9.6i and later 0.9.6 patch levels were released after
1039 *) Fix session ID handling in SSLv2 client code: the SERVER FINISHED
1040 code (06) was taken as the first octet of the session ID and the last
1041 octet was ignored consequently. As a result SSLv2 client side session
1042 caching could not have worked due to the session ID mismatch between
1044 Behaviour observed by Crispin Flowerday <crispin@flowerday.cx> as
1048 *) Change the declaration of needed Kerberos libraries to use EX_LIBS
1049 instead of the special (and badly supported) LIBKRB5. LIBKRB5 is
1053 *) The hw_ncipher.c engine requires dynamic locks. Unfortunately, it
1054 seems that in spite of existing for more than a year, many application
1055 author have done nothing to provide the necessary callbacks, which
1056 means that this particular engine will not work properly anywhere.
1057 This is a very unfortunate situation which forces us, in the name
1058 of usability, to give the hw_ncipher.c a static lock, which is part
1060 NOTE: This is for the 0.9.7 series ONLY. This hack will never
1061 appear in 0.9.8 or later. We EXPECT application authors to have
1062 dealt properly with this when 0.9.8 is released (unless we actually
1063 make such changes in the libcrypto locking code that changes will
1064 have to be made anyway).
1067 *) In asn1_d2i_read_bio() repeatedly call BIO_read() until all content
1068 octets have been read, EOF or an error occurs. Without this change
1069 some truncated ASN1 structures will not produce an error.
1072 *) Disable Heimdal support, since it hasn't been fully implemented.
1073 Still give the possibility to force the use of Heimdal, but with
1074 warnings and a request that patches get sent to openssl-dev.
1077 *) Add the VC-CE target, introduce the WINCE sysname, and add
1078 INSTALL.WCE and appropriate conditionals to make it build.
1079 [Steven Reddie <smr@essemer.com.au> via Richard Levitte]
1081 *) Change the DLL names for Cygwin to cygcrypto-x.y.z.dll and
1082 cygssl-x.y.z.dll, where x, y and z are the major, minor and
1083 edit numbers of the version.
1084 [Corinna Vinschen <vinschen@redhat.com> and Richard Levitte]
1086 *) Introduce safe string copy and catenation functions
1087 (BUF_strlcpy() and BUF_strlcat()).
1088 [Ben Laurie (CHATS) and Richard Levitte]
1090 *) Avoid using fixed-size buffers for one-line DNs.
1091 [Ben Laurie (CHATS)]
1093 *) Add BUF_MEM_grow_clean() to avoid information leakage when
1094 resizing buffers containing secrets, and use where appropriate.
1095 [Ben Laurie (CHATS)]
1097 *) Avoid using fixed size buffers for configuration file location.
1098 [Ben Laurie (CHATS)]
1100 *) Avoid filename truncation for various CA files.
1101 [Ben Laurie (CHATS)]
1103 *) Use sizeof in preference to magic numbers.
1104 [Ben Laurie (CHATS)]
1106 *) Avoid filename truncation in cert requests.
1107 [Ben Laurie (CHATS)]
1109 *) Add assertions to check for (supposedly impossible) buffer
1111 [Ben Laurie (CHATS)]
1113 *) Don't cache truncated DNS entries in the local cache (this could
1114 potentially lead to a spoofing attack).
1115 [Ben Laurie (CHATS)]
1117 *) Fix various buffers to be large enough for hex/decimal
1118 representations in a platform independent manner.
1119 [Ben Laurie (CHATS)]
1121 *) Add CRYPTO_realloc_clean() to avoid information leakage when
1122 resizing buffers containing secrets, and use where appropriate.
1123 [Ben Laurie (CHATS)]
1125 *) Add BIO_indent() to avoid much slightly worrying code to do
1127 [Ben Laurie (CHATS)]
1129 *) Convert sprintf()/BIO_puts() to BIO_printf().
1130 [Ben Laurie (CHATS)]
1132 *) buffer_gets() could terminate with the buffer only half
1134 [Ben Laurie (CHATS)]
1136 *) Add assertions to prevent user-supplied crypto functions from
1137 overflowing internal buffers by having large block sizes, etc.

1140 *) New OPENSSL_assert() macro (similar to assert(), but enabled
1142 [Ben Laurie (CHATS)]
1144 *) Eliminate unused copy of key in RC4.
1145 [Ben Laurie (CHATS)]
1147 *) Eliminate unused and incorrectly sized buffers for IV in pem.h.
1148 [Ben Laurie (CHATS)]
1150 *) Fix off-by-one error in EGD path.

1156 *) Eliminate unused and incorrectly sized X.509 structure
1158 [Ben Laurie (CHATS)]
1160 *) Eliminate unused and dangerous function knumber().
1161 [Ben Laurie (CHATS)]
1163 *) Eliminate unused and dangerous structure, KSSL_ERR.

1166 *) Protect against overlong session ID context length in an encoded
1167 session object. Since these are local, this does not appear to be
1169 [Ben Laurie (CHATS)]
1171 *) Change from security patch (see 0.9.6e below) that did not affect
1172 the 0.9.6 release series:
1174 Remote buffer overflow in SSL3 protocol - an attacker could
1175 supply an oversized master key in Kerberos-enabled versions.
1177 [Ben Laurie (CHATS)]
1179 *) Change the SSL kerb5 codes to match RFC 2712.
1182 *) Make -nameopt work fully for req and add -reqopt switch.
1183 [Michael Bell <michael.bell@rz.hu-berlin.de>, Steve Henson]
1185 *) The "block size" for block ciphers in CFB and OFB mode should be 1.
1186 [Steve Henson, reported by Yngve Nysaeter Pettersen <yngve@opera.com>]
1188 *) Make sure tests can be performed even if the corresponding algorithms
1189 have been removed entirely. This was also the last step to make
1190 OpenSSL compilable with DJGPP under all reasonable conditions.
1191 [Richard Levitte, Doug Kaufman <dkaufman@rahul.net>]
1193 *) Add cipher selection rules COMPLEMENTOFALL and COMPLEMENTOFDEFAULT
1194 to allow version independent disabling of normally unselected ciphers,
1195 which may be activated as a side-effect of selecting a single cipher.
1197 (E.g., cipher list string "RSA" enables ciphersuites that are left
1198 out of "ALL" because they do not provide symmetric encryption.
1199 "RSA:!COMPLEMEMENTOFALL" avoids these unsafe ciphersuites.)
1200 [Lutz Jaenicke, Bodo Moeller]
1202 *) Add appropriate support for separate platform-dependent build
1203 directories. The recommended way to make a platform-dependent
1204 build directory is the following (tested on Linux), maybe with
1207 # Place yourself outside of the OpenSSL source tree. In
1208 # this example, the environment variable OPENSSL_SOURCE
1209 # is assumed to contain the absolute OpenSSL source directory.
1210 mkdir -p objtree/"`uname -s`-`uname -r`-`uname -m`"
1211 cd objtree/"`uname -s`-`uname -r`-`uname -m`"
1212 (cd $OPENSSL_SOURCE; find . -type f) | while read F; do
1213 mkdir -p `dirname $F`
1214 ln -s $OPENSSL_SOURCE/$F $F
1217 To be absolutely sure not to disturb the source tree, a "make clean"
1218 is a good thing. If it isn't successfull, don't worry about it,
1219 it probably means the source directory is very clean.
1222 *) Make sure any ENGINE control commands make local copies of string
1223 pointers passed to them whenever necessary. Otherwise it is possible
1224 the caller may have overwritten (or deallocated) the original string
1225 data when a later ENGINE operation tries to use the stored values.
1226 [Götz Babin-Ebell <babinebell@trustcenter.de>]
1228 *) Improve diagnostics in file reading and command-line digests.
1229 [Ben Laurie aided and abetted by Solar Designer <solar@openwall.com>]
1231 *) Add AES modes CFB and OFB to the object database. Correct an
1232 error in AES-CFB decryption.
1235 *) Remove most calls to EVP_CIPHER_CTX_cleanup() in evp_enc.c, this
1236 allows existing EVP_CIPHER_CTX structures to be reused after
1237 calling EVP_*Final(). This behaviour is used by encryption
1238 BIOs and some applications. This has the side effect that
1239 applications must explicitly clean up cipher contexts with
1240 EVP_CIPHER_CTX_cleanup() or they will leak memory.
1243 *) Check the values of dna and dnb in bn_mul_recursive before calling
1244 bn_mul_comba (a non zero value means the a or b arrays do not contain
1245 n2 elements) and fallback to bn_mul_normal if either is not zero.
1248 *) Fix escaping of non-ASCII characters when using the -subj option
1249 of the "openssl req" command line tool. (Robert Joop <joop@fokus.gmd.de>)
1252 *) Make object definitions compliant to LDAP (RFC2256): SN is the short
1253 form for "surname", serialNumber has no short form.
1254 Use "mail" as the short name for "rfc822Mailbox" according to RFC2798;
1255 therefore remove "mail" short name for "internet 7".
1256 The OID for unique identifiers in X509 certificates is
1257 x500UniqueIdentifier, not uniqueIdentifier.
1258 Some more OID additions. (Michael Bell <michael.bell@rz.hu-berlin.de>)
1261 *) Add an "init" command to the ENGINE config module and auto initialize
1262 ENGINEs. Without any "init" command the ENGINE will be initialized
1263 after all ctrl commands have been executed on it. If init=1 the
1264 ENGINE is initailized at that point (ctrls before that point are run
1265 on the uninitialized ENGINE and after on the initialized one). If
1266 init=0 then the ENGINE will not be iniatialized at all.
1269 *) Fix the 'app_verify_callback' interface so that the user-defined
1270 argument is actually passed to the callback: In the
1271 SSL_CTX_set_cert_verify_callback() prototype, the callback
1272 declaration has been changed from
1275 int (*cb)(X509_STORE_CTX *,void *);
1276 in ssl_verify_cert_chain (ssl/ssl_cert.c), the call
1277 i=s->ctx->app_verify_callback(&ctx)
1278 has been changed into
1279 i=s->ctx->app_verify_callback(&ctx, s->ctx->app_verify_arg).
1281 To update applications using SSL_CTX_set_cert_verify_callback(),
1282 a dummy argument can be added to their callback functions.
1283 [D. K. Smetters <smetters@parc.xerox.com>]
1285 *) Added the '4758cca' ENGINE to support IBM 4758 cards.
1286 [Maurice Gittens <maurice@gittens.nl>, touchups by Geoff Thorpe]
1288 *) Add and OPENSSL_LOAD_CONF define which will cause
1289 OpenSSL_add_all_algorithms() to load the openssl.cnf config file.
1290 This allows older applications to transparently support certain
1291 OpenSSL features: such as crypto acceleration and dynamic ENGINE loading.
1292 Two new functions OPENSSL_add_all_algorithms_noconf() which will never
1293 load the config file and OPENSSL_add_all_algorithms_conf() which will
1294 always load it have also been added.
1297 *) Add the OFB, CFB and CTR (all with 128 bit feedback) to AES.
1298 Adjust NIDs and EVP layer.
1299 [Stephen Sprunk <stephen@sprunk.org> and Richard Levitte]
1301 *) Config modules support in openssl utility.
1303 Most commands now load modules from the config file,
1304 though in a few (such as version) this isn't done
1305 because it couldn't be used for anything.
1307 In the case of ca and req the config file used is
1308 the same as the utility itself: that is the -config
1309 command line option can be used to specify an
1313 *) Move default behaviour from OPENSSL_config(). If appname is NULL
1314 use "openssl_conf" if filename is NULL use default openssl config file.
1317 *) Add an argument to OPENSSL_config() to allow the use of an alternative
1318 config section name. Add a new flag to tolerate a missing config file
1319 and move code to CONF_modules_load_file().
1322 *) Support for crypto accelerator cards from Accelerated Encryption
1323 Processing, www.aep.ie. (Use engine 'aep')
1324 The support was copied from 0.9.6c [engine] and adapted/corrected
1325 to work with the new engine framework.
1326 [AEP Inc. and Richard Levitte]
1328 *) Support for SureWare crypto accelerator cards from Baltimore
1329 Technologies. (Use engine 'sureware')
1330 The support was copied from 0.9.6c [engine] and adapted
1331 to work with the new engine framework.
1334 *) Have the CHIL engine fork-safe (as defined by nCipher) and actually
1335 make the newer ENGINE framework commands for the CHIL engine work.
1336 [Toomas Kiisk <vix@cyber.ee> and Richard Levitte]
1338 *) Make it possible to produce shared libraries on ReliantUNIX.
1339 [Robert Dahlem <Robert.Dahlem@ffm2.siemens.de> via Richard Levitte]
1341 *) Add the configuration target debug-linux-ppro.
1342 Make 'openssl rsa' use the general key loading routines
1343 implemented in apps.c, and make those routines able to
1344 handle the key format FORMAT_NETSCAPE and the variant
1346 [Toomas Kiisk <vix@cyber.ee> via Richard Levitte]
1348 *) Fix a crashbug and a logic bug in hwcrhk_load_pubkey().
1349 [Toomas Kiisk <vix@cyber.ee> via Richard Levitte]
1351 *) Add -keyform to rsautl, and document -engine.
1352 [Richard Levitte, inspired by Toomas Kiisk <vix@cyber.ee>]
1354 *) Change BIO_new_file (crypto/bio/bss_file.c) to use new
1355 BIO_R_NO_SUCH_FILE error code rather than the generic
1356 ERR_R_SYS_LIB error code if fopen() fails with ENOENT.
1359 *) Add new functions
1361 ERR_peek_last_error_line
1362 ERR_peek_last_error_line_data.
1363 These are similar to
1366 ERR_peek_error_line_data,
1367 but report on the latest error recorded rather than the first one
1368 still in the error queue.
1369 [Ben Laurie, Bodo Moeller]
1371 *) default_algorithms option in ENGINE config module. This allows things
1373 default_algorithms = ALL
1374 default_algorithms = RSA, DSA, RAND, CIPHERS, DIGESTS
1377 *) Prelminary ENGINE config module.
1380 *) New experimental application configuration code.
1383 *) Change the AES code to follow the same name structure as all other
1384 symmetric ciphers, and behave the same way. Move everything to
1385 the directory crypto/aes, thereby obsoleting crypto/rijndael.
1386 [Stephen Sprunk <stephen@sprunk.org> and Richard Levitte]
1388 *) SECURITY: remove unsafe setjmp/signal interaction from ui_openssl.c.
1389 [Ben Laurie and Theo de Raadt]
1391 *) Add option to output public keys in req command.
1392 [Massimiliano Pala madwolf@openca.org]
1394 *) Use wNAFs in EC_POINTs_mul() for improved efficiency
1395 (up to about 10% better than before for P-192 and P-224).
1398 *) New functions/macros
1400 SSL_CTX_set_msg_callback(ctx, cb)
1401 SSL_CTX_set_msg_callback_arg(ctx, arg)
1402 SSL_set_msg_callback(ssl, cb)
1403 SSL_set_msg_callback_arg(ssl, arg)
1405 to request calling a callback function
1407 void cb(int write_p, int version, int content_type,
1408 const void *buf, size_t len, SSL *ssl, void *arg)
1410 whenever a protocol message has been completely received
1411 (write_p == 0) or sent (write_p == 1). Here 'version' is the
1412 protocol version according to which the SSL library interprets
1413 the current protocol message (SSL2_VERSION, SSL3_VERSION, or
1414 TLS1_VERSION). 'content_type' is 0 in the case of SSL 2.0, or
1415 the content type as defined in the SSL 3.0/TLS 1.0 protocol
1416 specification (change_cipher_spec(20), alert(21), handshake(22)).
1417 'buf' and 'len' point to the actual message, 'ssl' to the
1418 SSL object, and 'arg' is the application-defined value set by
1419 SSL[_CTX]_set_msg_callback_arg().
1421 'openssl s_client' and 'openssl s_server' have new '-msg' options
1422 to enable a callback that displays all protocol messages.
1425 *) Change the shared library support so shared libraries are built as
1426 soon as the corresponding static library is finished, and thereby get
1427 openssl and the test programs linked against the shared library.
1428 This still only happens when the keyword "shard" has been given to
1429 the configuration scripts.
1431 NOTE: shared library support is still an experimental thing, and
1432 backward binary compatibility is still not guaranteed.
1433 ["Maciej W. Rozycki" <macro@ds2.pg.gda.pl> and Richard Levitte]
1435 *) Add support for Subject Information Access extension.
1436 [Peter Sylvester <Peter.Sylvester@EdelWeb.fr>]
1438 *) Make BUF_MEM_grow() behaviour more consistent: Initialise to zero
1439 additional bytes when new memory had to be allocated, not just
1440 when reusing an existing buffer.
1443 *) New command line and configuration option 'utf8' for the req command.
1444 This allows field values to be specified as UTF8 strings.
1447 *) Add -multi and -mr options to "openssl speed" - giving multiple parallel
1448 runs for the former and machine-readable output for the latter.
1451 *) Add '-noemailDN' option to 'openssl ca'. This prevents inclusion
1452 of the e-mail address in the DN (i.e., it will go into a certificate
1453 extension only). The new configuration file option 'email_in_dn = no'
1454 has the same effect.
1455 [Massimiliano Pala madwolf@openca.org]
1457 *) Change all functions with names starting with des_ to be starting
1458 with DES_ instead. Add wrappers that are compatible with libdes,
1459 but are named _ossl_old_des_*. Finally, add macros that map the
1460 des_* symbols to the corresponding _ossl_old_des_* if libdes
1461 compatibility is desired. If OpenSSL 0.9.6c compatibility is
1462 desired, the des_* symbols will be mapped to DES_*, with one
1465 Since we provide two compatibility mappings, the user needs to
1466 define the macro OPENSSL_DES_LIBDES_COMPATIBILITY if libdes
1467 compatibility is desired. The default (i.e., when that macro
1468 isn't defined) is OpenSSL 0.9.6c compatibility.
1470 There are also macros that enable and disable the support of old
1471 des functions altogether. Those are OPENSSL_ENABLE_OLD_DES_SUPPORT
1472 and OPENSSL_DISABLE_OLD_DES_SUPPORT. If none or both of those
1473 are defined, the default will apply: to support the old des routines.
1475 In either case, one must include openssl/des.h to get the correct
1476 definitions. Do not try to just include openssl/des_old.h, that
1479 NOTE: This is a major break of an old API into a new one. Software
1480 authors are encouraged to switch to the DES_ style functions. Some
1481 time in the future, des_old.h and the libdes compatibility functions
1482 will be disable (i.e. OPENSSL_DISABLE_OLD_DES_SUPPORT will be the
1483 default), and then completely removed.
1486 *) Test for certificates which contain unsupported critical extensions.
1487 If such a certificate is found during a verify operation it is
1488 rejected by default: this behaviour can be overridden by either
1489 handling the new error X509_V_ERR_UNHANDLED_CRITICAL_EXTENSION or
1490 by setting the verify flag X509_V_FLAG_IGNORE_CRITICAL. A new function
1491 X509_supported_extension() has also been added which returns 1 if a
1492 particular extension is supported.
1495 *) Modify the behaviour of EVP cipher functions in similar way to digests
1496 to retain compatibility with existing code.
1499 *) Modify the behaviour of EVP_DigestInit() and EVP_DigestFinal() to retain
1500 compatibility with existing code. In particular the 'ctx' parameter does
1501 not have to be to be initialized before the call to EVP_DigestInit() and
1502 it is tidied up after a call to EVP_DigestFinal(). New function
1503 EVP_DigestFinal_ex() which does not tidy up the ctx. Similarly function
1504 EVP_MD_CTX_copy() changed to not require the destination to be
1505 initialized valid and new function EVP_MD_CTX_copy_ex() added which
1506 requires the destination to be valid.
1508 Modify all the OpenSSL digest calls to use EVP_DigestInit_ex(),
1509 EVP_DigestFinal_ex() and EVP_MD_CTX_copy_ex().
1512 *) Change ssl3_get_message (ssl/s3_both.c) and the functions using it
1513 so that complete 'Handshake' protocol structures are kept in memory
1514 instead of overwriting 'msg_type' and 'length' with 'body' data.
1517 *) Add an implementation of SSL_add_dir_cert_subjects_to_stack for Win32.
1518 [Massimo Santin via Richard Levitte]
1520 *) Major restructuring to the underlying ENGINE code. This includes
1521 reduction of linker bloat, separation of pure "ENGINE" manipulation
1522 (initialisation, etc) from functionality dealing with implementations
1523 of specific crypto iterfaces. This change also introduces integrated
1524 support for symmetric ciphers and digest implementations - so ENGINEs
1525 can now accelerate these by providing EVP_CIPHER and EVP_MD
1526 implementations of their own. This is detailed in crypto/engine/README
1527 as it couldn't be adequately described here. However, there are a few
1528 API changes worth noting - some RSA, DSA, DH, and RAND functions that
1529 were changed in the original introduction of ENGINE code have now
1530 reverted back - the hooking from this code to ENGINE is now a good
1531 deal more passive and at run-time, operations deal directly with
1532 RSA_METHODs, DSA_METHODs (etc) as they did before, rather than
1533 dereferencing through an ENGINE pointer any more. Also, the ENGINE
1534 functions dealing with BN_MOD_EXP[_CRT] handlers have been removed -
1535 they were not being used by the framework as there is no concept of a
1536 BIGNUM_METHOD and they could not be generalised to the new
1537 'ENGINE_TABLE' mechanism that underlies the new code. Similarly,
1538 ENGINE_cpy() has been removed as it cannot be consistently defined in
1542 *) Change ASN1_GENERALIZEDTIME_check() to allow fractional seconds.
1545 *) Change mkdef.pl to sort symbols that get the same entry number,
1546 and make sure the automatically generated functions ERR_load_*
1547 become part of libeay.num as well.
1550 *) New function SSL_renegotiate_pending(). This returns true once
1551 renegotiation has been requested (either SSL_renegotiate() call
1552 or HelloRequest/ClientHello receveived from the peer) and becomes
1553 false once a handshake has been completed.
1554 (For servers, SSL_renegotiate() followed by SSL_do_handshake()
1555 sends a HelloRequest, but does not ensure that a handshake takes
1556 place. SSL_renegotiate_pending() is useful for checking if the
1557 client has followed the request.)
1560 *) New SSL option SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION.
1561 By default, clients may request session resumption even during
1562 renegotiation (if session ID contexts permit); with this option,
1563 session resumption is possible only in the first handshake.
1565 SSL_OP_ALL is now 0x00000FFFL instead of 0x000FFFFFL. This makes
1566 more bits available for options that should not be part of
1567 SSL_OP_ALL (such as SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION).
1570 *) Add some demos for certificate and certificate request creation.
1573 *) Make maximum certificate chain size accepted from the peer application
1574 settable (SSL*_get/set_max_cert_list()), as proposed by
1575 "Douglas E. Engert" <deengert@anl.gov>.
1578 *) Add support for shared libraries for Unixware-7
1579 (Boyd Lynn Gerber <gerberb@zenez.com>).
1582 *) Add a "destroy" handler to ENGINEs that allows structural cleanup to
1583 be done prior to destruction. Use this to unload error strings from
1584 ENGINEs that load their own error strings. NB: This adds two new API
1585 functions to "get" and "set" this destroy handler in an ENGINE.
1588 *) Alter all existing ENGINE implementations (except "openssl" and
1589 "openbsd") to dynamically instantiate their own error strings. This
1590 makes them more flexible to be built both as statically-linked ENGINEs
1591 and self-contained shared-libraries loadable via the "dynamic" ENGINE.
1592 Also, add stub code to each that makes building them as self-contained
1593 shared-libraries easier (see README.ENGINE).
1596 *) Add a "dynamic" ENGINE that provides a mechanism for binding ENGINE
1597 implementations into applications that are completely implemented in
1598 self-contained shared-libraries. The "dynamic" ENGINE exposes control
1599 commands that can be used to configure what shared-library to load and
1600 to control aspects of the way it is handled. Also, made an update to
1601 the README.ENGINE file that brings its information up-to-date and
1602 provides some information and instructions on the "dynamic" ENGINE
1603 (ie. how to use it, how to build "dynamic"-loadable ENGINEs, etc).
1606 *) Make it possible to unload ranges of ERR strings with a new
1607 "ERR_unload_strings" function.
1610 *) Add a copy() function to EVP_MD.
1613 *) Make EVP_MD routines take a context pointer instead of just the
1614 md_data void pointer.
1617 *) Add flags to EVP_MD and EVP_MD_CTX. EVP_MD_FLAG_ONESHOT indicates
1618 that the digest can only process a single chunk of data
1619 (typically because it is provided by a piece of
1620 hardware). EVP_MD_CTX_FLAG_ONESHOT indicates that the application
1621 is only going to provide a single chunk of data, and hence the
1622 framework needn't accumulate the data for oneshot drivers.
1625 *) As with "ERR", make it possible to replace the underlying "ex_data"
1626 functions. This change also alters the storage and management of global
1627 ex_data state - it's now all inside ex_data.c and all "class" code (eg.
1628 RSA, BIO, SSL_CTX, etc) no longer stores its own STACKS and per-class
1629 index counters. The API functions that use this state have been changed
1630 to take a "class_index" rather than pointers to the class's local STACK
1631 and counter, and there is now an API function to dynamically create new
1632 classes. This centralisation allows us to (a) plug a lot of the
1633 thread-safety problems that existed, and (b) makes it possible to clean
1634 up all allocated state using "CRYPTO_cleanup_all_ex_data()". W.r.t. (b)
1635 such data would previously have always leaked in application code and
1636 workarounds were in place to make the memory debugging turn a blind eye
1637 to it. Application code that doesn't use this new function will still
1638 leak as before, but their memory debugging output will announce it now
1639 rather than letting it slide.
1641 Besides the addition of CRYPTO_cleanup_all_ex_data(), another API change
1642 induced by the "ex_data" overhaul is that X509_STORE_CTX_init() now
1643 has a return value to indicate success or failure.
1646 *) Make it possible to replace the underlying "ERR" functions such that the
1647 global state (2 LHASH tables and 2 locks) is only used by the "default"
1648 implementation. This change also adds two functions to "get" and "set"
1649 the implementation prior to it being automatically set the first time
1650 any other ERR function takes place. Ie. an application can call "get",
1651 pass the return value to a module it has just loaded, and that module
1652 can call its own "set" function using that value. This means the
1653 module's "ERR" operations will use (and modify) the error state in the
1654 application and not in its own statically linked copy of OpenSSL code.
1657 *) Give DH, DSA, and RSA types their own "**_up_ref()" function to increment
1658 reference counts. This performs normal REF_PRINT/REF_CHECK macros on
1659 the operation, and provides a more encapsulated way for external code
1660 (crypto/evp/ and ssl/) to do this. Also changed the evp and ssl code
1661 to use these functions rather than manually incrementing the counts.
1663 Also rename "DSO_up()" function to more descriptive "DSO_up_ref()".
1666 *) Add EVP test program.
1669 *) Add symmetric cipher support to ENGINE. Expect the API to change!
1672 *) New CRL functions: X509_CRL_set_version(), X509_CRL_set_issuer_name()
1673 X509_CRL_set_lastUpdate(), X509_CRL_set_nextUpdate(), X509_CRL_sort(),
1674 X509_REVOKED_set_serialNumber(), and X509_REVOKED_set_revocationDate().
1675 These allow a CRL to be built without having to access X509_CRL fields
1676 directly. Modify 'ca' application to use new functions.
1679 *) Move SSL_OP_TLS_ROLLBACK_BUG out of the SSL_OP_ALL list of recommended
1680 bug workarounds. Rollback attack detection is a security feature.
1681 The problem will only arise on OpenSSL servers when TLSv1 is not
1682 available (sslv3_server_method() or SSL_OP_NO_TLSv1).
1683 Software authors not wanting to support TLSv1 will have special reasons
1684 for their choice and can explicitly enable this option.
1685 [Bodo Moeller, Lutz Jaenicke]
1687 *) Rationalise EVP so it can be extended: don't include a union of
1688 cipher/digest structures, add init/cleanup functions for EVP_MD_CTX
1689 (similar to those existing for EVP_CIPHER_CTX).
1694 EVP_MD_CTX_init(&md); /* new function call */
1695 EVP_DigestInit(&md, EVP_sha1());
1696 EVP_DigestUpdate(&md, in, len);
1697 EVP_DigestFinal(&md, out, NULL);
1698 EVP_MD_CTX_cleanup(&md); /* new function call */
1702 *) Make DES key schedule conform to the usual scheme, as well as
1703 correcting its structure. This means that calls to DES functions
1704 now have to pass a pointer to a des_key_schedule instead of a
1705 plain des_key_schedule (which was actually always a pointer
1708 des_key_schedule ks;
1710 des_set_key_checked(..., &ks);
1711 des_ncbc_encrypt(..., &ks, ...);
1713 (Note that a later change renames 'des_...' into 'DES_...'.)
1716 *) Initial reduction of linker bloat: the use of some functions, such as
1717 PEM causes large amounts of unused functions to be linked in due to
1718 poor organisation. For example pem_all.c contains every PEM function
1719 which has a knock on effect of linking in large amounts of (unused)
1720 ASN1 code. Grouping together similar functions and splitting unrelated
1721 functions prevents this.
1724 *) Cleanup of EVP macros.
1727 *) Change historical references to {NID,SN,LN}_des_ede and ede3 to add the
1728 correct _ecb suffix.
1731 *) Add initial OCSP responder support to ocsp application. The
1732 revocation information is handled using the text based index
1733 use by the ca application. The responder can either handle
1734 requests generated internally, supplied in files (for example
1735 via a CGI script) or using an internal minimal server.
1738 *) Add configuration choices to get zlib compression for TLS.
1741 *) Changes to Kerberos SSL for RFC 2712 compliance:
1742 1. Implemented real KerberosWrapper, instead of just using
1743 KRB5 AP_REQ message. [Thanks to Simon Wilkinson <sxw@sxw.org.uk>]
1744 2. Implemented optional authenticator field of KerberosWrapper.
1746 Added openssl-style ASN.1 macros for Kerberos ticket, ap_req,
1747 and authenticator structs; see crypto/krb5/.
1749 Generalized Kerberos calls to support multiple Kerberos libraries.

1751 Jeffrey Altman <jaltman@columbia.edu>
1752 via Richard Levitte]
1754 *) Cause 'openssl speed' to use fully hard-coded DSA keys as it
1755 already does with RSA. testdsa.h now has 'priv_key/pub_key'
1756 values for each of the key sizes rather than having just
1757 parameters (and 'speed' generating keys each time).
1760 *) Speed up EVP routines.

1779 ["Brian Havard" <brianh@kheldar.apana.org.au> and Richard Levitte]
1781 *) Rewrite apps to use NCONF routines instead of the old CONF. New functions
1782 to support NCONF routines in extension code. New function CONF_set_nconf()
1783 to allow functions which take an NCONF to also handle the old LHASH
1784 structure: this means that the old CONF compatible routines can be
1785 retained (in particular wrt extensions) without having to duplicate the
1786 code. New function X509V3_add_ext_nconf_sk to add extensions to a stack.
1789 *) Enhance the general user interface with mechanisms for inner control
1790 and with possibilities to have yes/no kind of prompts.
1793 *) Change all calls to low level digest routines in the library and
1794 applications to use EVP. Add missing calls to HMAC_cleanup() and
1795 don't assume HMAC_CTX can be copied using memcpy().
1796 [Verdon Walker <VWalker@novell.com>, Steve Henson]
1798 *) Add the possibility to control engines through control names but with
1799 arbitrary arguments instead of just a string.
1800 Change the key loaders to take a UI_METHOD instead of a callback
1801 function pointer. NOTE: this breaks binary compatibility with earlier
1802 versions of OpenSSL [engine].
1803 Adapt the nCipher code for these new conditions and add a card insertion
1807 *) Enhance the general user interface with mechanisms to better support
1808 dialog box interfaces, application-defined prompts, the possibility
1809 to use defaults (for example default passwords from somewhere else)
1810 and interrupts/cancellations.
1813 *) Tidy up PKCS#12 attribute handling. Add support for the CSP name
1814 attribute in PKCS#12 files, add new -CSP option to pkcs12 utility.
1817 *) Fix a memory leak in 'sk_dup()' in the case reallocation fails. (Also
1818 tidy up some unnecessarily weird code in 'sk_new()').
1819 [Geoff, reported by Diego Tartara <dtartara@novamens.com>]
1821 *) Change the key loading routines for ENGINEs to use the same kind
1822 callback (pem_password_cb) as all other routines that need this
1826 *) Increase ENTROPY_NEEDED to 32 bytes, as Rijndael can operate with
1827 256 bit (=32 byte) keys. Of course seeding with more entropy bytes
1828 than this minimum value is recommended.
1831 *) New random seeder for OpenVMS, using the system process statistics
1832 that are easily reachable.
1835 *) Windows apparently can't transparently handle global
1836 variables defined in DLLs. Initialisations such as:
1838 const ASN1_ITEM *it = &ASN1_INTEGER_it;
1840 wont compile. This is used by the any applications that need to
1841 declare their own ASN1 modules. This was fixed by adding the option
1842 EXPORT_VAR_AS_FN to all Win32 platforms, although this isn't strictly
1843 needed for static libraries under Win32.
1846 *) New functions X509_PURPOSE_set() and X509_TRUST_set() to handle
1847 setting of purpose and trust fields. New X509_STORE trust and
1848 purpose functions and tidy up setting in other SSL functions.
1851 *) Add copies of X509_STORE_CTX fields and callbacks to X509_STORE
1852 structure. These are inherited by X509_STORE_CTX when it is
1853 initialised. This allows various defaults to be set in the
1854 X509_STORE structure (such as flags for CRL checking and custom
1855 purpose or trust settings) for functions which only use X509_STORE_CTX
1856 internally such as S/MIME.
1858 Modify X509_STORE_CTX_purpose_inherit() so it only sets purposes and
1859 trust settings if they are not set in X509_STORE. This allows X509_STORE
1860 purposes and trust (in S/MIME for example) to override any set by default.
1862 Add command line options for CRL checking to smime, s_client and s_server
1866 *) Initial CRL based revocation checking. If the CRL checking flag(s)
1867 are set then the CRL is looked up in the X509_STORE structure and
1868 its validity and signature checked, then if the certificate is found
1869 in the CRL the verify fails with a revoked error.
1871 Various new CRL related callbacks added to X509_STORE_CTX structure.
1873 Command line options added to 'verify' application to support this.
1875 This needs some additional work, such as being able to handle multiple
1876 CRLs with different times, extension based lookup (rather than just
1877 by subject name) and ultimately more complete V2 CRL extension
1881 *) Add a general user interface API (crypto/ui/). This is designed
1882 to replace things like des_read_password and friends (backward
1883 compatibility functions using this new API are provided).
1884 The purpose is to remove prompting functions from the DES code
1885 section as well as provide for prompting through dialog boxes in
1886 a window system and the like.
1889 *) Add "ex_data" support to ENGINE so implementations can add state at a
1890 per-structure level rather than having to store it globally.
1893 *) Make it possible for ENGINE structures to be copied when retrieved by
1894 ENGINE_by_id() if the ENGINE specifies a new flag: ENGINE_FLAGS_BY_ID_COPY.
1895 This causes the "original" ENGINE structure to act like a template,
1896 analogous to the RSA vs. RSA_METHOD type of separation. Because of this
1897 operational state can be localised to each ENGINE structure, despite the
1898 fact they all share the same "methods". New ENGINE structures returned in
1899 this case have no functional references and the return value is the single
1900 structural reference. This matches the single structural reference returned
1901 by ENGINE_by_id() normally, when it is incremented on the pre-existing
1905 *) Fix ASN1 decoder when decoding type ANY and V_ASN1_OTHER: since this
1906 needs to match any other type at all we need to manually clear the
1910 *) Changes to the "openssl engine" utility to include;
1911 - verbosity levels ('-v', '-vv', and '-vvv') that provide information
1912 about an ENGINE's available control commands.
1913 - executing control commands from command line arguments using the
1914 '-pre' and '-post' switches. '-post' is only used if '-t' is
1915 specified and the ENGINE is successfully initialised. The syntax for
1916 the individual commands are colon-separated, for example;
1917 openssl engine chil -pre FORK_CHECK:0 -pre SO_PATH:/lib/test.so
1920 *) New dynamic control command support for ENGINEs. ENGINEs can now
1921 declare their own commands (numbers), names (strings), descriptions,
1922 and input types for run-time discovery by calling applications. A
1923 subset of these commands are implicitly classed as "executable"
1924 depending on their input type, and only these can be invoked through
1925 the new string-based API function ENGINE_ctrl_cmd_string(). (Eg. this
1926 can be based on user input, config files, etc). The distinction is
1927 that "executable" commands cannot return anything other than a boolean
1928 result and can only support numeric or string input, whereas some
1929 discoverable commands may only be for direct use through
1930 ENGINE_ctrl(), eg. supporting the exchange of binary data, function
1931 pointers, or other custom uses. The "executable" commands are to
1932 support parameterisations of ENGINE behaviour that can be
1933 unambiguously defined by ENGINEs and used consistently across any
1934 OpenSSL-based application. Commands have been added to all the
1935 existing hardware-supporting ENGINEs, noticeably "SO_PATH" to allow
1936 control over shared-library paths without source code alterations.
1939 *) Changed all ENGINE implementations to dynamically allocate their
1940 ENGINEs rather than declaring them statically. Apart from this being
1941 necessary with the removal of the ENGINE_FLAGS_MALLOCED distinction,
1942 this also allows the implementations to compile without using the
1943 internal engine_int.h header.
1946 *) Minor adjustment to "rand" code. RAND_get_rand_method() now returns a
1947 'const' value. Any code that should be able to modify a RAND_METHOD
1948 should already have non-const pointers to it (ie. they should only
1949 modify their own ones).
1952 *) Made a variety of little tweaks to the ENGINE code.
1953 - "atalla" and "ubsec" string definitions were moved from header files
1954 to C code. "nuron" string definitions were placed in variables
1955 rather than hard-coded - allowing parameterisation of these values
1956 later on via ctrl() commands.
1957 - Removed unused "#if 0"'d code.
1958 - Fixed engine list iteration code so it uses ENGINE_free() to release
1959 structural references.
1960 - Constified the RAND_METHOD element of ENGINE structures.
1961 - Constified various get/set functions as appropriate and added
1962 missing functions (including a catch-all ENGINE_cpy that duplicates
1963 all ENGINE values onto a new ENGINE except reference counts/state).
1964 - Removed NULL parameter checks in get/set functions. Setting a method
1965 or function to NULL is a way of cancelling out a previously set
1966 value. Passing a NULL ENGINE parameter is just plain stupid anyway
1967 and doesn't justify the extra error symbols and code.
1968 - Deprecate the ENGINE_FLAGS_MALLOCED define and move the area for
1969 flags from engine_int.h to engine.h.
1970 - Changed prototypes for ENGINE handler functions (init(), finish(),
1971 ctrl(), key-load functions, etc) to take an (ENGINE*) parameter.
1974 *) Implement binary inversion algorithm for BN_mod_inverse in addition
1975 to the algorithm using long division. The binary algorithm can be
1976 used only if the modulus is odd. On 32-bit systems, it is faster
1977 only for relatively small moduli (roughly 20-30% for 128-bit moduli,
1978 roughly 5-15% for 256-bit moduli), so we use it only for moduli
1979 up to 450 bits. In 64-bit environments, the binary algorithm
1980 appears to be advantageous for much longer moduli; here we use it
1981 for moduli up to 2048 bits.
1984 *) Rewrite CHOICE field setting in ASN1_item_ex_d2i(). The old code
1985 could not support the combine flag in choice fields.
1988 *) Add a 'copy_extensions' option to the 'ca' utility. This copies
1989 extensions from a certificate request to the certificate.
1992 *) Allow multiple 'certopt' and 'nameopt' options to be separated
1993 by commas. Add 'namopt' and 'certopt' options to the 'ca' config
1994 file: this allows the display of the certificate about to be
1995 signed to be customised, to allow certain fields to be included
1996 or excluded and extension details. The old system didn't display
1997 multicharacter strings properly, omitted fields not in the policy
1998 and couldn't display additional details such as extensions.
2001 *) Function EC_POINTs_mul for multiple scalar multiplication
2002 of an arbitrary number of elliptic curve points
2003 \sum scalars[i]*points[i],
2004 optionally including the generator defined for the EC_GROUP:
2005 scalar*generator + \sum scalars[i]*points[i].
2007 EC_POINT_mul is a simple wrapper function for the typical case
2008 that the point list has just one item (besides the optional
2012 *) First EC_METHODs for curves over GF(p):
2014 EC_GFp_simple_method() uses the basic BN_mod_mul and BN_mod_sqr
2015 operations and provides various method functions that can also
2016 operate with faster implementations of modular arithmetic.
2018 EC_GFp_mont_method() reuses most functions that are part of
2019 EC_GFp_simple_method, but uses Montgomery arithmetic.
2021 [Bodo Moeller; point addition and point doubling
2022 implementation directly derived from source code provided by
2023 Lenka Fibikova <fibikova@exp-math.uni-essen.de>]
2025 *) Framework for elliptic curves (crypto/ec/ec.h, crypto/ec/ec_lcl.h,
2026 crypto/ec/ec_lib.c):
2028 Curves are EC_GROUP objects (with an optional group generator)
2029 based on EC_METHODs that are built into the library.
2031 Points are EC_POINT objects based on EC_GROUP objects.
2033 Most of the framework would be able to handle curves over arbitrary
2034 finite fields, but as there are no obvious types for fields other
2035 than GF(p), some functions are limited to that for now.
2038 *) Add the -HTTP option to s_server. It is similar to -WWW, but requires
2039 that the file contains a complete HTTP response.
2042 *) Add the ec directory to mkdef.pl and mkfiles.pl. In mkdef.pl
2043 change the def and num file printf format specifier from "%-40sXXX"
2044 to "%-39s XXX". The latter will always guarantee a space after the
2045 field while the former will cause them to run together if the field
2046 is 40 of more characters long.
2049 *) Constify the cipher and digest 'method' functions and structures
2050 and modify related functions to take constant EVP_MD and EVP_CIPHER
2054 *) Hide BN_CTX structure details in bn_lcl.h instead of publishing them
2055 in <openssl/bn.h>. Also further increase BN_CTX_NUM to 32.
2058 *) Modify EVP_Digest*() routines so they now return values. Although the
2059 internal software routines can never fail additional hardware versions
2063 *) Clean up crypto/err/err.h and change some error codes to avoid conflicts:
2065 Previously ERR_R_FATAL was too small and coincided with ERR_LIB_PKCS7
2066 (= ERR_R_PKCS7_LIB); it is now 64 instead of 32.
2069 ERR_R_NESTED_ASN1_ERROR
2071 ERR_R_MISSING_ASN1_EOS
2072 were 4 .. 9, conflicting with
2073 ERR_LIB_RSA (= ERR_R_RSA_LIB)
2075 ERR_LIB_PEM (= ERR_R_PEM_LIB).
2076 They are now 58 .. 63 (i.e., just below ERR_R_FATAL).
2078 Add new error code 'ERR_R_INTERNAL_ERROR'.
2081 *) Don't overuse locks in crypto/err/err.c: For data retrieval, CRYPTO_r_lock
2085 *) New option '-subj arg' for 'openssl req' and 'openssl ca'. This
2086 sets the subject name for a new request or supersedes the
2087 subject name in a given request. Formats that can be parsed are
2088 'CN=Some Name, OU=myOU, C=IT'
2090 'CN=Some Name/OU=myOU/C=IT'.
2092 Add options '-batch' and '-verbose' to 'openssl req'.
2093 [Massimiliano Pala <madwolf@hackmasters.net>]
2095 *) Introduce the possibility to access global variables through
2096 functions on platform were that's the best way to handle exporting
2097 global variables in shared libraries. To enable this functionality,
2098 one must configure with "EXPORT_VAR_AS_FN" or defined the C macro
2099 "OPENSSL_EXPORT_VAR_AS_FUNCTION" in crypto/opensslconf.h (the latter
2100 is normally done by Configure or something similar).
2102 To implement a global variable, use the macro OPENSSL_IMPLEMENT_GLOBAL
2103 in the source file (foo.c) like this:
2105 OPENSSL_IMPLEMENT_GLOBAL(int,foo)=1;
2106 OPENSSL_IMPLEMENT_GLOBAL(double,bar);
2108 To declare a global variable, use the macros OPENSSL_DECLARE_GLOBAL
2109 and OPENSSL_GLOBAL_REF in the header file (foo.h) like this:
2111 OPENSSL_DECLARE_GLOBAL(int,foo);
2112 #define foo OPENSSL_GLOBAL_REF(foo)
2113 OPENSSL_DECLARE_GLOBAL(double,bar);
2114 #define bar OPENSSL_GLOBAL_REF(bar)
2116 The #defines are very important, and therefore so is including the
2117 header file everywhere where the defined globals are used.
2119 The macro OPENSSL_EXPORT_VAR_AS_FUNCTION also affects the definition
2120 of ASN.1 items, but that structure is a bit different.
2122 The largest change is in util/mkdef.pl which has been enhanced with
2123 better and easier to understand logic to choose which symbols should
2124 go into the Windows .def files as well as a number of fixes and code
2125 cleanup (among others, algorithm keywords are now sorted
2126 lexicographically to avoid constant rewrites).
2129 *) In BN_div() keep a copy of the sign of 'num' before writing the
2130 result to 'rm' because if rm==num the value will be overwritten
2131 and produce the wrong result if 'num' is negative: this caused
2132 problems with BN_mod() and BN_nnmod().
2135 *) Function OCSP_request_verify(). This checks the signature on an
2136 OCSP request and verifies the signer certificate. The signer
2137 certificate is just checked for a generic purpose and OCSP request
2141 *) Add OCSP_check_validity() function to check the validity of OCSP
2142 responses. OCSP responses are prepared in real time and may only
2143 be a few seconds old. Simply checking that the current time lies
2144 between thisUpdate and nextUpdate max reject otherwise valid responses
2145 caused by either OCSP responder or client clock inaccuracy. Instead
2146 we allow thisUpdate and nextUpdate to fall within a certain period of
2147 the current time. The age of the response can also optionally be
2148 checked. Two new options -validity_period and -status_age added to
2152 *) If signature or public key algorithm is unrecognized print out its
2153 OID rather that just UNKNOWN.
2156 *) Change OCSP_cert_to_id() to tolerate a NULL subject certificate and
2157 OCSP_cert_id_new() a NULL serialNumber. This allows a partial certificate
2158 ID to be generated from the issuer certificate alone which can then be
2159 passed to OCSP_id_issuer_cmp().
2162 *) New compilation option ASN1_ITEM_FUNCTIONS. This causes the new
2163 ASN1 modules to export functions returning ASN1_ITEM pointers
2164 instead of the ASN1_ITEM structures themselves. This adds several
2165 new macros which allow the underlying ASN1 function/structure to
2166 be accessed transparently. As a result code should not use ASN1_ITEM
2167 references directly (such as &X509_it) but instead use the relevant
2168 macros (such as ASN1_ITEM_rptr(X509)). This option is to allow
2169 use of the new ASN1 code on platforms where exporting structures
2170 is problematical (for example in shared libraries) but exporting
2171 functions returning pointers to structures is not.
2174 *) Add support for overriding the generation of SSL/TLS session IDs.
2175 These callbacks can be registered either in an SSL_CTX or per SSL.
2176 The purpose of this is to allow applications to control, if they wish,
2177 the arbitrary values chosen for use as session IDs, particularly as it
2178 can be useful for session caching in multiple-server environments. A
2179 command-line switch for testing this (and any client code that wishes
2180 to use such a feature) has been added to "s_server".
2181 [Geoff Thorpe, Lutz Jaenicke]
2183 *) Modify mkdef.pl to recognise and parse preprocessor conditionals
2184 of the form '#if defined(...) || defined(...) || ...' and
2185 '#if !defined(...) && !defined(...) && ...'. This also avoids
2186 the growing number of special cases it was previously handling.
2189 *) Make all configuration macros available for application by making
2190 sure they are available in opensslconf.h, by giving them names starting
2191 with "OPENSSL_" to avoid conflicts with other packages and by making
2192 sure e_os2.h will cover all platform-specific cases together with
2194 Additionally, it is now possible to define configuration/platform-
2195 specific names (called "system identities"). In the C code, these
2196 are prefixed with "OPENSSL_SYSNAME_". e_os2.h will create another
2197 macro with the name beginning with "OPENSSL_SYS_", which is determined
2198 from "OPENSSL_SYSNAME_*" or compiler-specific macros depending on
2202 *) New option -set_serial to 'req' and 'x509' this allows the serial
2203 number to use to be specified on the command line. Previously self
2204 signed certificates were hard coded with serial number 0 and the
2205 CA options of 'x509' had to use a serial number in a file which was
2209 *) New options to 'ca' utility to support V2 CRL entry extensions.
2210 Currently CRL reason, invalidity date and hold instruction are
2211 supported. Add new CRL extensions to V3 code and some new objects.
2214 *) New function EVP_CIPHER_CTX_set_padding() this is used to
2215 disable standard block padding (aka PKCS#5 padding) in the EVP
2216 API, which was previously mandatory. This means that the data is
2217 not padded in any way and so the total length much be a multiple
2218 of the block size, otherwise an error occurs.
2221 *) Initial (incomplete) OCSP SSL support.
2224 *) New function OCSP_parse_url(). This splits up a URL into its host,
2225 port and path components: primarily to parse OCSP URLs. New -url
2226 option to ocsp utility.
2229 *) New nonce behavior. The return value of OCSP_check_nonce() now
2230 reflects the various checks performed. Applications can decide
2231 whether to tolerate certain situations such as an absent nonce
2232 in a response when one was present in a request: the ocsp application
2233 just prints out a warning. New function OCSP_add1_basic_nonce()
2234 this is to allow responders to include a nonce in a response even if
2235 the request is nonce-less.
2238 *) Disable stdin buffering in load_cert (apps/apps.c) so that no certs are
2239 skipped when using openssl x509 multiple times on a single input file,
2240 e.g. "(openssl x509 -out cert1; openssl x509 -out cert2) <certs".
2243 *) Make ASN1_UTCTIME_set_string() and ASN1_GENERALIZEDTIME_set_string()
2244 set string type: to handle setting ASN1_TIME structures. Fix ca
2245 utility to correctly initialize revocation date of CRLs.
2248 *) New option SSL_OP_CIPHER_SERVER_PREFERENCE allows the server to override
2249 the clients preferred ciphersuites and rather use its own preferences.
2250 Should help to work around M$ SGC (Server Gated Cryptography) bug in
2251 Internet Explorer by ensuring unchanged hash method during stepup.
2252 (Also replaces the broken/deactivated SSL_OP_NON_EXPORT_FIRST option.)
2255 *) Make mkdef.pl recognise all DECLARE_ASN1 macros, change rijndael
2256 to aes and add a new 'exist' option to print out symbols that don't
2260 *) Additional options to ocsp utility to allow flags to be set and
2261 additional certificates supplied.
2264 *) Add the option -VAfile to 'openssl ocsp', so the user can give the
2265 OCSP client a number of certificate to only verify the response
2269 *) Update Rijndael code to version 3.0 and change EVP AES ciphers to
2270 handle the new API. Currently only ECB, CBC modes supported. Add new
2273 Add TLS AES ciphersuites as described in RFC3268, "Advanced
2274 Encryption Standard (AES) Ciphersuites for Transport Layer
2275 Security (TLS)". (In beta versions of OpenSSL 0.9.7, these were
2276 not enabled by default and were not part of the "ALL" ciphersuite
2277 alias because they were not yet official; they could be
2278 explicitly requested by specifying the "AESdraft" ciphersuite
2279 group alias. In the final release of OpenSSL 0.9.7, the group
2280 alias is called "AES" and is part of "ALL".)
2281 [Ben Laurie, Steve Henson, Bodo Moeller]
2283 *) New function OCSP_copy_nonce() to copy nonce value (if present) from
2284 request to response.
2287 *) Functions for OCSP responders. OCSP_request_onereq_count(),
2288 OCSP_request_onereq_get0(), OCSP_onereq_get0_id() and OCSP_id_get0_info()
2289 extract information from a certificate request. OCSP_response_create()
2290 creates a response and optionally adds a basic response structure.
2291 OCSP_basic_add1_status() adds a complete single response to a basic
2292 response and returns the OCSP_SINGLERESP structure just added (to allow
2293 extensions to be included for example). OCSP_basic_add1_cert() adds a
2294 certificate to a basic response and OCSP_basic_sign() signs a basic
2295 response with various flags. New helper functions ASN1_TIME_check()
2296 (checks validity of ASN1_TIME structure) and ASN1_TIME_to_generalizedtime()
2297 (converts ASN1_TIME to GeneralizedTime).
2300 *) Various new functions. EVP_Digest() combines EVP_Digest{Init,Update,Final}()
2301 in a single operation. X509_get0_pubkey_bitstr() extracts the public_key
2302 structure from a certificate. X509_pubkey_digest() digests the public_key
2303 contents: this is used in various key identifiers.
2306 *) Make sk_sort() tolerate a NULL argument.
2307 [Steve Henson reported by Massimiliano Pala <madwolf@comune.modena.it>]
2309 *) New OCSP verify flag OCSP_TRUSTOTHER. When set the "other" certificates
2310 passed by the function are trusted implicitly. If any of them signed the
2311 response then it is assumed to be valid and is not verified.
2314 *) In PKCS7_set_type() initialise content_type in PKCS7_ENC_CONTENT
2315 to data. This was previously part of the PKCS7 ASN1 code. This
2316 was causing problems with OpenSSL created PKCS#12 and PKCS#7 structures.
2317 [Steve Henson, reported by Kenneth R. Robinette
2318 <support@securenetterm.com>]
2320 *) Add CRYPTO_push_info() and CRYPTO_pop_info() calls to new ASN1
2321 routines: without these tracing memory leaks is very painful.
2322 Fix leaks in PKCS12 and PKCS7 routines.
2325 *) Make X509_time_adj() cope with the new behaviour of ASN1_TIME_new().
2326 Previously it initialised the 'type' argument to V_ASN1_UTCTIME which
2327 effectively meant GeneralizedTime would never be used. Now it
2328 is initialised to -1 but X509_time_adj() now has to check the value
2329 and use ASN1_TIME_set() if the value is not V_ASN1_UTCTIME or
2330 V_ASN1_GENERALIZEDTIME, without this it always uses GeneralizedTime.
2331 [Steve Henson, reported by Kenneth R. Robinette
2332 <support@securenetterm.com>]
2334 *) Fixes to BN_to_ASN1_INTEGER when bn is zero. This would previously
2335 result in a zero length in the ASN1_INTEGER structure which was
2336 not consistent with the structure when d2i_ASN1_INTEGER() was used
2337 and would cause ASN1_INTEGER_cmp() to fail. Enhance s2i_ASN1_INTEGER()
2338 to cope with hex and negative integers. Fix bug in i2a_ASN1_INTEGER()
2339 where it did not print out a minus for negative ASN1_INTEGER.
2342 *) Add summary printout to ocsp utility. The various functions which
2343 convert status values to strings have been renamed to:
2344 OCSP_response_status_str(), OCSP_cert_status_str() and
2345 OCSP_crl_reason_str() and are no longer static. New options
2346 to verify nonce values and to disable verification. OCSP response
2347 printout format cleaned up.
2350 *) Add additional OCSP certificate checks. These are those specified
2351 in RFC2560. This consists of two separate checks: the CA of the
2352 certificate being checked must either be the OCSP signer certificate
2353 or the issuer of the OCSP signer certificate. In the latter case the
2354 OCSP signer certificate must contain the OCSP signing extended key
2355 usage. This check is performed by attempting to match the OCSP
2356 signer or the OCSP signer CA to the issuerNameHash and issuerKeyHash
2357 in the OCSP_CERTID structures of the response.
2360 *) Initial OCSP certificate verification added to OCSP_basic_verify()
2361 and related routines. This uses the standard OpenSSL certificate
2362 verify routines to perform initial checks (just CA validity) and
2363 to obtain the certificate chain. Then additional checks will be
2364 performed on the chain. Currently the root CA is checked to see
2365 if it is explicitly trusted for OCSP signing. This is used to set
2366 a root CA as a global signing root: that is any certificate that
2367 chains to that CA is an acceptable OCSP signing certificate.
2370 *) New '-extfile ...' option to 'openssl ca' for reading X.509v3
2371 extensions from a separate configuration file.
2372 As when reading extensions from the main configuration file,
2373 the '-extensions ...' option may be used for specifying the
2375 [Massimiliano Pala <madwolf@comune.modena.it>]
2377 *) New OCSP utility. Allows OCSP requests to be generated or
2378 read. The request can be sent to a responder and the output
2379 parsed, outputed or printed in text form. Not complete yet:
2380 still needs to check the OCSP response validity.
2383 *) New subcommands for 'openssl ca':
2384 'openssl ca -status <serial>' prints the status of the cert with
2385 the given serial number (according to the index file).
2386 'openssl ca -updatedb' updates the expiry status of certificates
2388 [Massimiliano Pala <madwolf@comune.modena.it>]
2390 *) New '-newreq-nodes' command option to CA.pl. This is like
2391 '-newreq', but calls 'openssl req' with the '-nodes' option
2392 so that the resulting key is not encrypted.
2393 [Damien Miller <djm@mindrot.org>]
2395 *) New configuration for the GNU Hurd.
2396 [Jonathan Bartlett <johnnyb@wolfram.com> via Richard Levitte]
2398 *) Initial code to implement OCSP basic response verify. This
2399 is currently incomplete. Currently just finds the signer's
2400 certificate and verifies the signature on the response.
2403 *) New SSLeay_version code SSLEAY_DIR to determine the compiled-in
2404 value of OPENSSLDIR. This is available via the new '-d' option
2405 to 'openssl version', and is also included in 'openssl version -a'.
2408 *) Allowing defining memory allocation callbacks that will be given
2409 file name and line number information in additional arguments
2410 (a const char* and an int). The basic functionality remains, as
2411 well as the original possibility to just replace malloc(),
2412 realloc() and free() by functions that do not know about these
2413 additional arguments. To register and find out the current
2414 settings for extended allocation functions, the following
2415 functions are provided:
2417 CRYPTO_set_mem_ex_functions
2418 CRYPTO_set_locked_mem_ex_functions
2419 CRYPTO_get_mem_ex_functions
2420 CRYPTO_get_locked_mem_ex_functions
2422 These work the same way as CRYPTO_set_mem_functions and friends.
2423 CRYPTO_get_[locked_]mem_functions now writes 0 where such an
2424 extended allocation function is enabled.
2425 Similarly, CRYPTO_get_[locked_]mem_ex_functions writes 0 where
2426 a conventional allocation function is enabled.
2427 [Richard Levitte, Bodo Moeller]
2429 *) Finish off removing the remaining LHASH function pointer casts.
2430 There should no longer be any prototype-casting required when using
2431 the LHASH abstraction, and any casts that remain are "bugs". See
2432 the callback types and macros at the head of lhash.h for details
2433 (and "OBJ_cleanup" in crypto/objects/obj_dat.c as an example).
2436 *) Add automatic query of EGD sockets in RAND_poll() for the unix variant.
2437 If /dev/[u]random devices are not available or do not return enough
2438 entropy, EGD style sockets (served by EGD or PRNGD) will automatically
2440 The locations /var/run/egd-pool, /dev/egd-pool, /etc/egd-pool, and
2441 /etc/entropy will be queried once each in this sequence, quering stops
2442 when enough entropy was collected without querying more sockets.
2445 *) Change the Unix RAND_poll() variant to be able to poll several
2446 random devices, as specified by DEVRANDOM, until a sufficient amount
2447 of data has been collected. We spend at most 10 ms on each file
2448 (select timeout) and read in non-blocking mode. DEVRANDOM now
2449 defaults to the list "/dev/urandom", "/dev/random", "/dev/srandom"
2450 (previously it was just the string "/dev/urandom"), so on typical
2451 platforms the 10 ms delay will never occur.
2452 Also separate out the Unix variant to its own file, rand_unix.c.
2453 For VMS, there's a currently-empty rand_vms.c.
2456 *) Move OCSP client related routines to ocsp_cl.c. These
2457 provide utility functions which an application needing
2458 to issue a request to an OCSP responder and analyse the
2459 response will typically need: as opposed to those which an
2460 OCSP responder itself would need which will be added later.
2462 OCSP_request_sign() signs an OCSP request with an API similar
2463 to PKCS7_sign(). OCSP_response_status() returns status of OCSP
2464 response. OCSP_response_get1_basic() extracts basic response
2465 from response. OCSP_resp_find_status(): finds and extracts status
2466 information from an OCSP_CERTID structure (which will be created
2467 when the request structure is built). These are built from lower
2468 level functions which work on OCSP_SINGLERESP structures but
2469 wont normally be used unless the application wishes to examine
2470 extensions in the OCSP response for example.
2472 Replace nonce routines with a pair of functions.
2473 OCSP_request_add1_nonce() adds a nonce value and optionally
2474 generates a random value. OCSP_check_nonce() checks the
2475 validity of the nonce in an OCSP response.
2478 *) Change function OCSP_request_add() to OCSP_request_add0_id().
2479 This doesn't copy the supplied OCSP_CERTID and avoids the
2480 need to free up the newly created id. Change return type
2481 to OCSP_ONEREQ to return the internal OCSP_ONEREQ structure.
2482 This can then be used to add extensions to the request.
2483 Deleted OCSP_request_new(), since most of its functionality
2484 is now in OCSP_REQUEST_new() (and the case insensitive name
2485 clash) apart from the ability to set the request name which
2486 will be added elsewhere.
2489 *) Update OCSP API. Remove obsolete extensions argument from
2490 various functions. Extensions are now handled using the new
2491 OCSP extension code. New simple OCSP HTTP function which
2492 can be used to send requests and parse the response.
2495 *) Fix the PKCS#7 (S/MIME) code to work with new ASN1. Two new
2496 ASN1_ITEM structures help with sign and verify. PKCS7_ATTR_SIGN
2497 uses the special reorder version of SET OF to sort the attributes
2498 and reorder them to match the encoded order. This resolves a long
2499 standing problem: a verify on a PKCS7 structure just after signing
2500 it used to fail because the attribute order did not match the
2501 encoded order. PKCS7_ATTR_VERIFY does not reorder the attributes:
2502 it uses the received order. This is necessary to tolerate some broken
2503 software that does not order SET OF. This is handled by encoding
2504 as a SEQUENCE OF but using implicit tagging (with UNIVERSAL class)
2505 to produce the required SET OF.
2508 *) Have mk1mf.pl generate the macros OPENSSL_BUILD_SHLIBCRYPTO and
2509 OPENSSL_BUILD_SHLIBSSL and use them appropriately in the header
2510 files to get correct declarations of the ASN.1 item variables.
2513 *) Rewrite of PKCS#12 code to use new ASN1 functionality. Replace many
2514 PKCS#12 macros with real functions. Fix two unrelated ASN1 bugs:
2515 asn1_check_tlen() would sometimes attempt to use 'ctx' when it was
2516 NULL and ASN1_TYPE was not dereferenced properly in asn1_ex_c2i().
2517 New ASN1 macro: DECLARE_ASN1_ITEM() which just declares the relevant
2518 ASN1_ITEM and no wrapper functions.
2521 *) New functions or ASN1_item_d2i_fp() and ASN1_item_d2i_bio(). These
2522 replace the old function pointer based I/O routines. Change most of
2523 the *_d2i_bio() and *_d2i_fp() functions to use these.
2526 *) Enhance mkdef.pl to be more accepting about spacing in C preprocessor
2527 lines, recognice more "algorithms" that can be deselected, and make
2528 it complain about algorithm deselection that isn't recognised.
2531 *) New ASN1 functions to handle dup, sign, verify, digest, pack and
2532 unpack operations in terms of ASN1_ITEM. Modify existing wrappers
2533 to use new functions. Add NO_ASN1_OLD which can be set to remove
2534 some old style ASN1 functions: this can be used to determine if old
2535 code will still work when these eventually go away.
2538 *) New extension functions for OCSP structures, these follow the
2539 same conventions as certificates and CRLs.
2542 *) New function X509V3_add1_i2d(). This automatically encodes and
2543 adds an extension. Its behaviour can be customised with various
2544 flags to append, replace or delete. Various wrappers added for
2545 certifcates and CRLs.
2548 *) Fix to avoid calling the underlying ASN1 print routine when
2549 an extension cannot be parsed. Correct a typo in the
2550 OCSP_SERVICELOC extension. Tidy up print OCSP format.
2553 *) Make mkdef.pl parse some of the ASN1 macros and add apropriate
2554 entries for variables.
2557 *) Add functionality to apps/openssl.c for detecting locking
2558 problems: As the program is single-threaded, all we have
2559 to do is register a locking callback using an array for
2560 storing which locks are currently held by the program.
2563 *) Use a lock around the call to CRYPTO_get_ex_new_index() in
2564 SSL_get_ex_data_X509_STORE_idx(), which is used in
2565 ssl_verify_cert_chain() and thus can be called at any time
2566 during TLS/SSL handshakes so that thread-safety is essential.
2567 Unfortunately, the ex_data design is not at all suited
2568 for multi-threaded use, so it probably should be abolished.
2571 *) Added Broadcom "ubsec" ENGINE to OpenSSL.
2572 [Broadcom, tweaked and integrated by Geoff Thorpe]
2574 *) Move common extension printing code to new function
2575 X509V3_print_extensions(). Reorganise OCSP print routines and
2576 implement some needed OCSP ASN1 functions. Add OCSP extensions.
2579 *) New function X509_signature_print() to remove duplication in some
2583 *) Add a special meaning when SET OF and SEQUENCE OF flags are both
2584 set (this was treated exactly the same as SET OF previously). This
2585 is used to reorder the STACK representing the structure to match the
2586 encoding. This will be used to get round a problem where a PKCS7
2587 structure which was signed could not be verified because the STACK
2588 order did not reflect the encoded order.
2591 *) Reimplement the OCSP ASN1 module using the new code.
2594 *) Update the X509V3 code to permit the use of an ASN1_ITEM structure
2595 for its ASN1 operations. The old style function pointers still exist
2596 for now but they will eventually go away.
2599 *) Merge in replacement ASN1 code from the ASN1 branch. This almost
2600 completely replaces the old ASN1 functionality with a table driven
2601 encoder and decoder which interprets an ASN1_ITEM structure describing
2602 the ASN1 module. Compatibility with the existing ASN1 API (i2d,d2i) is
2603 largely maintained. Almost all of the old asn1_mac.h macro based ASN1
2604 has also been converted to the new form.
2607 *) Change BN_mod_exp_recp so that negative moduli are tolerated
2608 (the sign is ignored). Similarly, ignore the sign in BN_MONT_CTX_set
2609 so that BN_mod_exp_mont and BN_mod_exp_mont_word work
2610 for negative moduli.
2613 *) Fix BN_uadd and BN_usub: Always return non-negative results instead
2614 of not touching the result's sign bit.
2617 *) BN_div bugfix: If the result is 0, the sign (res->neg) must not be
2621 *) Changed the LHASH code to use prototypes for callbacks, and created
2622 macros to declare and implement thin (optionally static) functions
2623 that provide type-safety and avoid function pointer casting for the
2624 type-specific callbacks.
2627 *) Added Kerberos Cipher Suites to be used with TLS, as written in
2629 [Veers Staats <staatsvr@asc.hpc.mil>,
2630 Jeffrey Altman <jaltman@columbia.edu>, via Richard Levitte]
2632 *) Reformat the FAQ so the different questions and answers can be divided
2633 in sections depending on the subject.
2636 *) Have the zlib compression code load ZLIB.DLL dynamically under
2640 *) New function BN_mod_sqrt for computing square roots modulo a prime
2641 (using the probabilistic Tonelli-Shanks algorithm unless
2642 p == 3 (mod 4) or p == 5 (mod 8), which are cases that can
2643 be handled deterministically).
2644 [Lenka Fibikova <fibikova@exp-math.uni-essen.de>, Bodo Moeller]
2646 *) Make BN_mod_inverse faster by explicitly handling small quotients
2647 in the Euclid loop. (Speed gain about 20% for small moduli [256 or
2648 512 bits], about 30% for larger ones [1024 or 2048 bits].)
2651 *) New function BN_kronecker.
2654 *) Fix BN_gcd so that it works on negative inputs; the result is
2655 positive unless both parameters are zero.
2656 Previously something reasonably close to an infinite loop was
2657 possible because numbers could be growing instead of shrinking
2658 in the implementation of Euclid's algorithm.
2661 *) Fix BN_is_word() and BN_is_one() macros to take into account the
2662 sign of the number in question.
2664 Fix BN_is_word(a,w) to work correctly for w == 0.
2666 The old BN_is_word(a,w) macro is now called BN_abs_is_word(a,w)
2667 because its test if the absolute value of 'a' equals 'w'.
2668 Note that BN_abs_is_word does *not* handle w == 0 reliably;
2669 it exists mostly for use in the implementations of BN_is_zero(),
2670 BN_is_one(), and BN_is_word().
2673 *) New function BN_swap.
2676 *) Use BN_nnmod instead of BN_mod in crypto/bn/bn_exp.c so that
2677 the exponentiation functions are more likely to produce reasonable
2678 results on negative inputs.
2681 *) Change BN_mod_mul so that the result is always non-negative.
2682 Previously, it could be negative if one of the factors was negative;
2683 I don't think anyone really wanted that behaviour.
2686 *) Move BN_mod_... functions into new file crypto/bn/bn_mod.c
2687 (except for exponentiation, which stays in crypto/bn/bn_exp.c,
2688 and BN_mod_mul_reciprocal, which stays in crypto/bn/bn_recp.c)
2689 and add new functions:
2698 BN_mod_lshift1_quick
2702 These functions always generate non-negative results.
2704 BN_nnmod otherwise is like BN_mod (if BN_mod computes a remainder r
2705 such that |m| < r < 0, BN_nnmod will output rem + |m| instead).
2707 BN_mod_XXX_quick(r, a, [b,] m) generates the same result as
2708 BN_mod_XXX(r, a, [b,] m, ctx), but requires that a [and b]
2709 be reduced modulo m.
2710 [Lenka Fibikova <fibikova@exp-math.uni-essen.de>, Bodo Moeller]
2713 The following entry accidentily appeared in the CHANGES file
2714 distributed with OpenSSL 0.9.7. The modifications described in
2715 it do *not* apply to OpenSSL 0.9.7.
2717 *) Remove a few calls to bn_wexpand() in BN_sqr() (the one in there
2718 was actually never needed) and in BN_mul(). The removal in BN_mul()
2719 required a small change in bn_mul_part_recursive() and the addition
2720 of the functions bn_cmp_part_words(), bn_sub_part_words() and
2721 bn_add_part_words(), which do the same thing as bn_cmp_words(),
2722 bn_sub_words() and bn_add_words() except they take arrays with
2727 *) In 'openssl passwd', verify passwords read from the terminal
2728 unless the '-salt' option is used (which usually means that
2729 verification would just waste user's time since the resulting
2730 hash is going to be compared with some given password hash)
2731 or the new '-noverify' option is used.
2733 This is an incompatible change, but it does not affect
2734 non-interactive use of 'openssl passwd' (passwords on the command
2735 line, '-stdin' option, '-in ...' option) and thus should not
2739 *) Remove all references to RSAref, since there's no more need for it.
2742 *) Make DSO load along a path given through an environment variable
2743 (SHLIB_PATH) with shl_load().
2746 *) Constify the ENGINE code as a result of BIGNUM constification.
2747 Also constify the RSA code and most things related to it. In a
2748 few places, most notable in the depth of the ASN.1 code, ugly
2749 casts back to non-const were required (to be solved at a later
2753 *) Make it so the openssl application has all engines loaded by default.
2756 *) Constify the BIGNUM routines a little more.
2759 *) Add the following functions:
2761 ENGINE_load_cswift()
2763 ENGINE_load_atalla()
2765 ENGINE_load_builtin_engines()
2767 That way, an application can itself choose if external engines that
2768 are built-in in OpenSSL shall ever be used or not. The benefit is
2769 that applications won't have to be linked with libdl or other dso
2770 libraries unless it's really needed.
2772 Changed 'openssl engine' to load all engines on demand.
2773 Changed the engine header files to avoid the duplication of some
2774 declarations (they differed!).
2777 *) 'openssl engine' can now list capabilities.
2780 *) Better error reporting in 'openssl engine'.
2783 *) Never call load_dh_param(NULL) in s_server.
2786 *) Add engine application. It can currently list engines by name and
2787 identity, and test if they are actually available.
2790 *) Improve RPM specification file by forcing symbolic linking and making
2791 sure the installed documentation is also owned by root.root.
2792 [Damien Miller <djm@mindrot.org>]
2794 *) Give the OpenSSL applications more possibilities to make use of
2795 keys (public as well as private) handled by engines.
2798 *) Add OCSP code that comes from CertCo.
2801 *) Add VMS support for the Rijndael code.
2804 *) Added untested support for Nuron crypto accelerator.
2807 *) Add support for external cryptographic devices. This code was
2808 previously distributed separately as the "engine" branch.
2809 [Geoff Thorpe, Richard Levitte]
2811 *) Rework the filename-translation in the DSO code. It is now possible to
2812 have far greater control over how a "name" is turned into a filename
2813 depending on the operating environment and any oddities about the
2814 different shared library filenames on each system.
2817 *) Support threads on FreeBSD-elf in Configure.
2820 *) Fix for SHA1 assembly problem with MASM: it produces
2821 warnings about corrupt line number information when assembling
2822 with debugging information. This is caused by the overlapping
2824 [Bernd Matthes <mainbug@celocom.de>, Steve Henson]
2827 NCONF_get_number() has no error checking at all. As a replacement,
2828 NCONF_get_number_e() is defined (_e for "error checking") and is
2829 promoted strongly. The old NCONF_get_number is kept around for
2830 binary backward compatibility.
2831 Make it possible for methods to load from something other than a BIO,
2832 by providing a function pointer that is given a name instead of a BIO.
2833 For example, this could be used to load configuration data from an
2837 *) Fix for non blocking accept BIOs. Added new I/O special reason
2838 BIO_RR_ACCEPT to cover this case. Previously use of accept BIOs
2839 with non blocking I/O was not possible because no retry code was
2840 implemented. Also added new SSL code SSL_WANT_ACCEPT to cover
2844 *) Added the beginnings of Rijndael support.
2847 *) Fix for bug in DirectoryString mask setting. Add support for
2848 X509_NAME_print_ex() in 'req' and X509_print_ex() function
2849 to allow certificate printing to more controllable, additional
2850 'certopt' option to 'x509' to allow new printing options to be
2854 *) Clean old EAY MD5 hack from e_os.h.
2857 Changes between 0.9.6l and 0.9.6m [17 Mar 2004]
2859 *) Fix null-pointer assignment in do_change_cipher_spec() revealed
2860 by using the Codenomicon TLS Test Tool (CAN-2004-0079)
2861 [Joe Orton, Steve Henson]
2863 Changes between 0.9.6k and 0.9.6l [04 Nov 2003]
2865 *) Fix additional bug revealed by the NISCC test suite:
2867 Stop bug triggering large recursion when presented with
2868 certain ASN.1 tags (CAN-2003-0851)
2871 Changes between 0.9.6j and 0.9.6k [30 Sep 2003]
2873 *) Fix various bugs revealed by running the NISCC test suite:
2875 Stop out of bounds reads in the ASN1 code when presented with
2876 invalid tags (CAN-2003-0543 and CAN-2003-0544).
2878 If verify callback ignores invalid public key errors don't try to check
2879 certificate signature with the NULL public key.
2883 *) In ssl3_accept() (ssl/s3_srvr.c) only accept a client certificate
2884 if the server requested one: as stated in TLS 1.0 and SSL 3.0
2888 *) In ssl3_get_client_hello() (ssl/s3_srvr.c), tolerate additional
2889 extra data after the compression methods not only for TLS 1.0
2890 but also for SSL 3.0 (as required by the specification).
2891 [Bodo Moeller; problem pointed out by Matthias Loepfe]
2893 *) Change X509_certificate_type() to mark the key as exported/exportable
2894 when it's 512 *bits* long, not 512 bytes.
2897 Changes between 0.9.6i and 0.9.6j [10 Apr 2003]
2899 *) Countermeasure against the Klima-Pokorny-Rosa extension of
2900 Bleichbacher's attack on PKCS #1 v1.5 padding: treat
2901 a protocol version number mismatch like a decryption error
2902 in ssl3_get_client_key_exchange (ssl/s3_srvr.c).
2905 *) Turn on RSA blinding by default in the default implementation
2906 to avoid a timing attack. Applications that don't want it can call
2907 RSA_blinding_off() or use the new flag RSA_FLAG_NO_BLINDING.
2908 They would be ill-advised to do so in most cases.
2909 [Ben Laurie, Steve Henson, Geoff Thorpe, Bodo Moeller]
2911 *) Change RSA blinding code so that it works when the PRNG is not
2912 seeded (in this case, the secret RSA exponent is abused as
2913 an unpredictable seed -- if it is not unpredictable, there
2914 is no point in blinding anyway). Make RSA blinding thread-safe
2915 by remembering the creator's thread ID in rsa->blinding and
2916 having all other threads use local one-time blinding factors
2917 (this requires more computation than sharing rsa->blinding, but
2918 avoids excessive locking; and if an RSA object is not shared
2919 between threads, blinding will still be very fast).
2922 Changes between 0.9.6h and 0.9.6i [19 Feb 2003]
2924 *) In ssl3_get_record (ssl/s3_pkt.c), minimize information leaked
2925 via timing by performing a MAC computation even if incorrrect
2926 block cipher padding has been found. This is a countermeasure
2927 against active attacks where the attacker has to distinguish
2928 between bad padding and a MAC verification error. (CAN-2003-0078)
2930 [Bodo Moeller; problem pointed out by Brice Canvel (EPFL),
2931 Alain Hiltgen (UBS), Serge Vaudenay (EPFL), and
2932 Martin Vuagnoux (EPFL, Ilion)]
2934 Changes between 0.9.6g and 0.9.6h [5 Dec 2002]
2936 *) New function OPENSSL_cleanse(), which is used to cleanse a section of
2937 memory from it's contents. This is done with a counter that will
2938 place alternating values in each byte. This can be used to solve
2939 two issues: 1) the removal of calls to memset() by highly optimizing
2940 compilers, and 2) cleansing with other values than 0, since those can
2941 be read through on certain media, for example a swap space on disk.
2944 *) Bugfix: client side session caching did not work with external caching,
2945 because the session->cipher setting was not restored when reloading
2946 from the external cache. This problem was masked, when
2947 SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG (part of SSL_OP_ALL) was set.
2948 (Found by Steve Haslam <steve@araqnid.ddts.net>.)
2951 *) Fix client_certificate (ssl/s2_clnt.c): The permissible total
2952 length of the REQUEST-CERTIFICATE message is 18 .. 34, not 17 .. 33.
2953 [Zeev Lieber <zeev-l@yahoo.com>]
2955 *) Undo an undocumented change introduced in 0.9.6e which caused
2956 repeated calls to OpenSSL_add_all_ciphers() and
2957 OpenSSL_add_all_digests() to be ignored, even after calling
2961 *) Change the default configuration reader to deal with last line not
2962 being properly terminated.
2965 *) Change X509_NAME_cmp() so it applies the special rules on handling
2966 DN values that are of type PrintableString, as well as RDNs of type
2967 emailAddress where the value has the type ia5String.
2968 [stefank@valicert.com via Richard Levitte]
2970 *) Add a SSL_SESS_CACHE_NO_INTERNAL_STORE flag to take over half
2971 the job SSL_SESS_CACHE_NO_INTERNAL_LOOKUP was inconsistently
2972 doing, define a new flag (SSL_SESS_CACHE_NO_INTERNAL) to be
2973 the bitwise-OR of the two for use by the majority of applications
2974 wanting this behaviour, and update the docs. The documented
2975 behaviour and actual behaviour were inconsistent and had been
2976 changing anyway, so this is more a bug-fix than a behavioural
2978 [Geoff Thorpe, diagnosed by Nadav Har'El]
2980 *) Don't impose a 16-byte length minimum on session IDs in ssl/s3_clnt.c
2981 (the SSL 3.0 and TLS 1.0 specifications allow any length up to 32 bytes).
2984 *) Fix initialization code race conditions in
2985 SSLv23_method(), SSLv23_client_method(), SSLv23_server_method(),
2986 SSLv2_method(), SSLv2_client_method(), SSLv2_server_method(),

2991 [Patrick McCormick <patrick@tellme.com>, Bodo Moeller]
2993 *) Reorder cleanup sequence in SSL_CTX_free(): only remove the ex_data after
2994 the cached sessions are flushed, as the remove_cb() might use ex_data
2995 contents. Bug found by Sam Varshavchik <mrsam@courier-mta.com>
2996 (see [openssl.org #212]).
2997 [Geoff Thorpe, Lutz Jaenicke]
2999 *) Fix typo in OBJ_txt2obj which incorrectly passed the content
3000 length, instead of the encoding length to d2i_ASN1_OBJECT.
3003 Changes between 0.9.6f and 0.9.6g [9 Aug 2002]
3005 *) [In 0.9.6g-engine release:]
3006 Fix crypto/engine/vendor_defns/cswift.h for WIN32 (use '_stdcall').
3007 [Lynn Gazis <lgazis@rainbow.com>]
3009 Changes between 0.9.6e and 0.9.6f [8 Aug 2002]

3012 and get fix the header length calculation.
3013 [Florian Weimer <Weimer@CERT.Uni-Stuttgart.DE>,
3014 Alon Kantor <alonk@checkpoint.com> (and others),
3017 *) Use proper error handling instead of 'assertions' in buffer
3018 overflow checks added in 0.9.6e. This prevents DoS (the
3019 assertions could call abort()).
3020 [Arne Ansper <arne@ats.cyber.ee>, Bodo Moeller]
3022 Changes between 0.9.6d and 0.9.6e [30 Jul 2002]
3024 *) Add various sanity checks to asn1_get_length() to reject
3025 the ASN1 length bytes if they exceed sizeof(long), will appear
3026 negative or the content length exceeds the length of the
3028 [Steve Henson, Adi Stav <stav@mercury.co.il>, James Yonan <jim@ntlp.com>]
3030 *) Fix cipher selection routines: ciphers without encryption had no flags
3031 for the cipher strength set and where therefore not handled correctly
3032 by the selection routines (PR #130).
3035 *) Fix EVP_dsa_sha macro.
3039 SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS
3040 for disabling the SSL 3.0/TLS 1.0 CBC vulnerability countermeasure
3041 that was added in OpenSSL 0.9.6d.
3043 As the countermeasure turned out to be incompatible with some
3044 broken SSL implementations, the new option is part of SSL_OP_ALL.
3045 SSL_OP_ALL is usually employed when compatibility with weird SSL
3046 implementations is desired (e.g. '-bugs' option to 's_client' and
3047 's_server'), so the new option is automatically set in many
3051 *) Changes in security patch:
3053 Changes marked "(CHATS)" were sponsored by the Defense Advanced
3054 Research Projects Agency (DARPA) and Air Force Research Laboratory,
3055 Air Force Materiel Command, USAF, under agreement number
3058 *) Add various sanity checks to asn1_get_length() to reject
3059 the ASN1 length bytes if they exceed sizeof(long), will appear
3060 negative or the content length exceeds the length of the
3061 supplied buffer. (CAN-2002-0659)

3064 *) Assertions for various potential buffer overflows, not known to

3068 *) Various temporary buffers to hold ASCII versions of integers were
3069 too small for 64 bit platforms. (CAN-2002-0655)
3070 [Matthew Byng-Maddick <mbm@aldigital.co.uk> and Ben Laurie (CHATS)>

3073 supply an oversized session ID to a client. (CAN-2002-0656)

3076 *) Remote buffer overflow in SSL2 protocol - an attacker could
3077 supply an oversized client master key. (CAN-2002-0656)
3078 [Ben Laurie (CHATS)]
3080 Changes between 0.9.6c and 0.9.6d [9 May 2002]
3082 *) Fix crypto/asn1/a_sign.c so that 'parameters' is omitted (not
3083 encoded as NULL) with id-dsa-with-sha1.
3084 [Nils Larsch <nla@trustcenter.de>; problem pointed out by Bodo Moeller]
3086 *) Check various X509_...() return values in apps/req.c.
3087 [Nils Larsch <nla@trustcenter.de>]
3089 *) Fix BASE64 decode (EVP_DecodeUpdate) for data with CR/LF ended lines:
3090 an end-of-file condition would erronously be flagged, when the CRLF
3091 was just at the end of a processed block. The bug was discovered when
3092 processing data through a buffering memory BIO handing the data to a
3093 BASE64-decoding BIO. Bug fund and patch submitted by Pavel Tsekov
3094 <ptsekov@syntrex.com> and Nedelcho Stanev.
3097 *) Implement a countermeasure against a vulnerability recently found
3098 in CBC ciphersuites in SSL 3.0/TLS 1.0: Send an empty fragment
3099 before application data chunks to avoid the use of known IVs
3100 with data potentially chosen by the attacker.
3103 *) Fix length checks in ssl3_get_client_hello().
3106 *) TLS/SSL library bugfix: use s->s3->in_read_app_data differently
3107 to prevent ssl3_read_internal() from incorrectly assuming that
3108 ssl3_read_bytes() found application data while handshake
3109 processing was enabled when in fact s->s3->in_read_app_data was
3110 merely automatically cleared during the initial handshake.
3111 [Bodo Moeller; problem pointed out by Arne Ansper <arne@ats.cyber.ee>]
3113 *) Fix object definitions for Private and Enterprise: they were not
3114 recognized in their shortname (=lowercase) representation. Extend
3115 obj_dat.pl to issue an error when using undefined keywords instead
3116 of silently ignoring the problem (Svenning Sorensen
3117 <sss@sss.dnsalias.net>).
3120 *) Fix DH_generate_parameters() so that it works for 'non-standard'
3121 generators, i.e. generators other than 2 and 5. (Previously, the
3122 code did not properly initialise the 'add' and 'rem' values to
3123 BN_generate_prime().)
3125 In the new general case, we do not insist that 'generator' is
3126 actually a primitive root: This requirement is rather pointless;
3127 a generator of the order-q subgroup is just as good, if not
3131 *) Map new X509 verification errors to alerts. Discovered and submitted by
3132 Tom Wu <tom@arcot.com>.
3135 *) Fix ssl3_pending() (ssl/s3_lib.c) to prevent SSL_pending() from
3136 returning non-zero before the data has been completely received
3137 when using non-blocking I/O.
3138 [Bodo Moeller; problem pointed out by John Hughes]
3140 *) Some of the ciphers missed the strength entry (SSL_LOW etc).
3141 [Ben Laurie, Lutz Jaenicke]
3143 *) Fix bug in SSL_clear(): bad sessions were not removed (found by
3144 Yoram Zahavi <YoramZ@gilian.com>).
3147 *) Add information about CygWin 1.3 and on, and preserve proper
3148 configuration for the versions before that.
3149 [Corinna Vinschen <vinschen@redhat.com> and Richard Levitte]
3151 *) Make removal from session cache (SSL_CTX_remove_session()) more robust:
3152 check whether we deal with a copy of a session and do not delete from
3153 the cache in this case. Problem reported by "Izhar Shoshani Levi"
3154 <izhar@checkpoint.com>.
3157 *) Do not store session data into the internal session cache, if it
3158 is never intended to be looked up (SSL_SESS_CACHE_NO_INTERNAL_LOOKUP
3159 flag is set). Proposed by Aslam <aslam@funk.com>.

3170 *) Add the configuration target linux-s390x.
3171 [Neale Ferguson <Neale.Ferguson@SoftwareAG-USA.com> via Richard Levitte]
3173 *) The earlier bugfix for the SSL3_ST_SW_HELLO_REQ_C case of
3174 ssl3_accept (ssl/s3_srvr.c) incorrectly used a local flag
3175 variable as an indication that a ClientHello message has been
3176 received. As the flag value will be lost between multiple
3177 invocations of ssl3_accept when using non-blocking I/O, the
3178 function may not be aware that a handshake has actually taken
3179 place, thus preventing a new session from being added to the
3182 To avoid this problem, we now set s->new_session to 2 instead of
3183 using a local variable.
3184 [Lutz Jaenicke, Bodo Moeller]
3186 *) Bugfix: Return -1 from ssl3_get_server_done (ssl3/s3_clnt.c)
3187 if the SSL_R_LENGTH_MISMATCH error is detected.
3188 [Geoff Thorpe, Bodo Moeller]
3190 *) New 'shared_ldflag' column in Configure platform table.
3193 *) Fix EVP_CIPHER_mode macro.
3194 ["Dan S. Camper" <dan@bti.net>]
3196 *) Fix ssl3_read_bytes (ssl/s3_pkt.c): To ignore messages of unknown
3197 type, we must throw them away by setting rr->length to 0.
3198 [D P Chang <dpc@qualys.com>]
3200 Changes between 0.9.6b and 0.9.6c [21 dec 2001]
3202 *) Fix BN_rand_range bug pointed out by Dominikus Scherkl
3203 <Dominikus.Scherkl@biodata.com>. (The previous implementation
3204 worked incorrectly for those cases where range = 10..._2 and
3205 3*range is two bits longer than range.)
3208 *) Only add signing time to PKCS7 structures if it is not already
3212 *) Fix crypto/objects/objects.h: "ld-ce" should be "id-ce",
3213 OBJ_ld_ce should be OBJ_id_ce.
3214 Also some ip-pda OIDs in crypto/objects/objects.txt were
3215 incorrect (cf. RFC 3039).
3216 [Matt Cooper, Frederic Giudicelli, Bodo Moeller]
3218 *) Release CRYPTO_LOCK_DYNLOCK when CRYPTO_destroy_dynlockid()
3219 returns early because it has nothing to do.
3220 [Andy Schneider <andy.schneider@bjss.co.uk>]
3222 *) [In 0.9.6c-engine release:]
3223 Fix mutex callback return values in crypto/engine/hw_ncipher.c.
3224 [Andy Schneider <andy.schneider@bjss.co.uk>]
3226 *) [In 0.9.6c-engine release:]
3227 Add support for Cryptographic Appliance's keyserver technology.
3228 (Use engine 'keyclient')
3229 [Cryptographic Appliances and Geoff Thorpe]
3231 *) Add a configuration entry for OS/390 Unix. The C compiler 'c89'
3232 is called via tools/c89.sh because arguments have to be
3233 rearranged (all '-L' options must appear before the first object
3235 [Richard Shapiro <rshapiro@abinitio.com>]
3237 *) [In 0.9.6c-engine release:]
3238 Add support for Broadcom crypto accelerator cards, backported
3240 [Broadcom, Nalin Dahyabhai <nalin@redhat.com>, Mark Cox]
3242 *) [In 0.9.6c-engine release:]
3243 Add support for SureWare crypto accelerator cards from
3244 Baltimore Technologies. (Use engine 'sureware')
3245 [Baltimore Technologies and Mark Cox]
3247 *) [In 0.9.6c-engine release:]
3248 Add support for crypto accelerator cards from Accelerated
3249 Encryption Processing, www.aep.ie. (Use engine 'aep')
3250 [AEP Inc. and Mark Cox]
3252 *) Add a configuration entry for gcc on UnixWare.
3253 [Gary Benson <gbenson@redhat.com>]
3255 *) Change ssl/s2_clnt.c and ssl/s2_srvr.c so that received handshake
3256 messages are stored in a single piece (fixed-length part and
3257 variable-length part combined) and fix various bugs found on the way.
3260 *) Disable caching in BIO_gethostbyname(), directly use gethostbyname()
3261 instead. BIO_gethostbyname() does not know what timeouts are
3262 appropriate, so entries would stay in cache even when they have
3264 [Bodo Moeller; problem pointed out by Rich Salz <rsalz@zolera.com>
3266 *) Change ssl23_get_client_hello (ssl/s23_srvr.c) behaviour when
3267 faced with a pathologically small ClientHello fragment that does
3268 not contain client_version: Instead of aborting with an error,
3269 simply choose the highest available protocol version (i.e.,
3270 TLS 1.0 unless it is disabled). In practice, ClientHello
3271 messages are never sent like this, but this change gives us
3272 strictly correct behaviour at least for TLS.
3275 *) Fix SSL handshake functions and SSL_clear() such that SSL_clear()
3276 never resets s->method to s->ctx->method when called from within
3277 one of the SSL handshake functions.
3278 [Bodo Moeller; problem pointed out by Niko Baric]
3280 *) In ssl3_get_client_hello (ssl/s3_srvr.c), generate a fatal alert
3281 (sent using the client's version number) if client_version is
3282 smaller than the protocol version in use. Also change
3283 ssl23_get_client_hello (ssl/s23_srvr.c) to select TLS 1.0 if
3284 the client demanded SSL 3.0 but only TLS 1.0 is enabled; then
3285 the client will at least see that alert.
3288 *) Fix ssl3_get_message (ssl/s3_both.c) to handle message fragmentation
3292 *) Avoid infinite loop in ssl3_get_message (ssl/s3_both.c) if a
3293 client receives HelloRequest while in a handshake.
3294 [Bodo Moeller; bug noticed by Andy Schneider <andy.schneider@bjss.co.uk>]
3296 *) Bugfix in ssl3_accept (ssl/s3_srvr.c): Case SSL3_ST_SW_HELLO_REQ_C
3297 should end in 'break', not 'goto end' which circuments various
3298 cleanups done in state SSL_ST_OK. But session related stuff
3299 must be disabled for SSL_ST_OK in the case that we just sent a
3302 Also avoid some overhead by not calling ssl_init_wbio_buffer()
3303 before just sending a HelloRequest.
3304 [Bodo Moeller, Eric Rescorla <ekr@rtfm.com>]
3306 *) Fix ssl/s3_enc.c, ssl/t1_enc.c and ssl/s3_pkt.c so that we don't
3307 reveal whether illegal block cipher padding was found or a MAC
3308 verification error occured. (Neither SSLerr() codes nor alerts
3309 are directly visible to potential attackers, but the information
3310 may leak via logfiles.)
3312 Similar changes are not required for the SSL 2.0 implementation
3313 because the number of padding bytes is sent in clear for SSL 2.0,
3314 and the extra bytes are just ignored. However ssl/s2_pkt.c
3315 failed to verify that the purported number of padding bytes is in
3319 *) Add OpenUNIX-8 support including shared libraries
3320 (Boyd Lynn Gerber <gerberb@zenez.com>).
3323 *) Improve RSA_padding_check_PKCS1_OAEP() check again to avoid
3324 'wristwatch attack' using huge encoding parameters (cf.
3325 James H. Manger's CRYPTO 2001 paper). Note that the
3326 RSA_PKCS1_OAEP_PADDING case of RSA_private_decrypt() does not use
3327 encoding parameters and hence was not vulnerable.
3330 *) BN_sqr() bug fix.
3331 [Ulf Möller, reported by Jim Ellis <jim.ellis@cavium.com>]
3333 *) Rabin-Miller test analyses assume uniformly distributed witnesses,
3334 so use BN_pseudo_rand_range() instead of using BN_pseudo_rand()
3335 followed by modular reduction.
3336 [Bodo Moeller; pointed out by Adam Young <AYoung1@NCSUS.JNJ.COM>]
3338 *) Add BN_pseudo_rand_range() with obvious functionality: BN_rand_range()
3339 equivalent based on BN_pseudo_rand() instead of BN_rand().
3342 *) s3_srvr.c: allow sending of large client certificate lists (> 16 kB).
3343 This function was broken, as the check for a new client hello message
3344 to handle SGC did not allow these large messages.
3345 (Tracked down by "Douglas E. Engert" <deengert@anl.gov>.)
3348 *) Add alert descriptions for TLSv1 to SSL_alert_desc_string[_long]().
3351 *) Fix buggy behaviour of BIO_get_num_renegotiates() and BIO_ctrl()
3352 for BIO_C_GET_WRITE_BUF_SIZE ("Stephen Hinton" <shinton@netopia.com>).
3355 *) Rework the configuration and shared library support for Tru64 Unix.
3356 The configuration part makes use of modern compiler features and
3357 still retains old compiler behavior for those that run older versions
3358 of the OS. The shared library support part includes a variant that
3359 uses the RPATH feature, and is available through the special
3360 configuration target "alpha-cc-rpath", which will never be selected
3362 [Tim Mooney <mooney@dogbert.cc.ndsu.NoDak.edu> via Richard Levitte]
3364 *) In ssl3_get_key_exchange (ssl/s3_clnt.c), call ssl3_get_message()
3365 with the same message size as in ssl3_get_certificate_request().
3366 Otherwise, if no ServerKeyExchange message occurs, CertificateRequest
3367 messages might inadvertently be reject as too long.
3368 [Petr Lampa <lampa@fee.vutbr.cz>]
3370 *) Enhanced support for IA-64 Unix platforms (well, Linux and HP-UX).
3373 *) Modified SSL library such that the verify_callback that has been set
3374 specificly for an SSL object with SSL_set_verify() is actually being
3375 used. Before the change, a verify_callback set with this function was
3376 ignored and the verify_callback() set in the SSL_CTX at the time of
3377 the call was used. New function X509_STORE_CTX_set_verify_cb() introduced
3378 to allow the necessary settings.
3381 *) Initialize static variable in crypto/dsa/dsa_lib.c and crypto/dh/dh_lib.c
3382 explicitly to NULL, as at least on Solaris 8 this seems not always to be
3383 done automatically (in contradiction to the requirements of the C
3384 standard). This made problems when used from OpenSSH.
3387 *) In OpenSSL 0.9.6a and 0.9.6b, crypto/dh/dh_key.c ignored
3388 dh->length and always used
3390 BN_rand_range(priv_key, dh->p).
3392 BN_rand_range() is not necessary for Diffie-Hellman, and this
3393 specific range makes Diffie-Hellman unnecessarily inefficient if
3394 dh->length (recommended exponent length) is much smaller than the
3395 length of dh->p. We could use BN_rand_range() if the order of
3396 the subgroup was stored in the DH structure, but we only have
3401 BN_rand(priv_key, l, ...)
3403 where 'l' is dh->length if this is defined, or BN_num_bits(dh->p)-1
3409 RSA_eay_public_encrypt
3410 RSA_eay_private_decrypt
3411 RSA_eay_private_encrypt (signing)
3412 RSA_eay_public_decrypt (signature verification)
3414 (default implementations for RSA_public_encrypt,
3415 RSA_private_decrypt, RSA_private_encrypt, RSA_public_decrypt),
3416 always reject numbers >= n.
3419 *) In crypto/rand/md_rand.c, use a new short-time lock CRYPTO_LOCK_RAND2
3420 to synchronize access to 'locking_thread'. This is necessary on
3421 systems where access to 'locking_thread' (an 'unsigned long'
3422 variable) is not atomic.
3425 *) In crypto/rand/md_rand.c, set 'locking_thread' to current thread's ID
3426 *before* setting the 'crypto_lock_rand' flag. The previous code had
3427 a race condition if 0 is a valid thread ID.
3428 [Travis Vitek <vitek@roguewave.com>]
3430 *) Add support for shared libraries under Irix.
3431 [Albert Chin-A-Young <china@thewrittenword.com>]
3433 *) Add configuration option to build on Linux on both big-endian and
3435 [Ralf Baechle <ralf@uni-koblenz.de>]
3437 *) Add the possibility to create shared libraries on HP-UX.
3440 Changes between 0.9.6a and 0.9.6b [9 Jul 2001]
3442 *) Change ssleay_rand_bytes (crypto/rand/md_rand.c)
3443 to avoid a SSLeay/OpenSSL PRNG weakness pointed out by
3444 Markku-Juhani O. Saarinen <markku-juhani.saarinen@nokia.com>:
3445 PRNG state recovery was possible based on the output of
3446 one PRNG request appropriately sized to gain knowledge on
3447 'md' followed by enough consecutive 1-byte PRNG requests
3448 to traverse all of 'state'.
3450 1. When updating 'md_local' (the current thread's copy of 'md')
3451 during PRNG output generation, hash all of the previous
3452 'md_local' value, not just the half used for PRNG output.
3454 2. Make the number of bytes from 'state' included into the hash
3455 independent from the number of PRNG bytes requested.
3457 The first measure alone would be sufficient to avoid
3458 Markku-Juhani's attack. (Actually it had never occurred
3459 to me that the half of 'md_local' used for chaining was the
3460 half from which PRNG output bytes were taken -- I had always
3461 assumed that the secret half would be used.) The second
3462 measure makes sure that additional data from 'state' is never
3463 mixed into 'md_local' in small portions; this heuristically
3464 further strengthens the PRNG.
3467 *) Fix crypto/bn/asm/mips3.s.
3470 *) When only the key is given to "enc", the IV is undefined. Print out
3471 an error message in this case.
3474 *) Handle special case when X509_NAME is empty in X509 printing routines.
3477 *) In dsa_do_verify (crypto/dsa/dsa_ossl.c), verify that r and s are
3478 positive and less than q.
3481 *) Don't change *pointer in CRYPTO_add_lock() is add_lock_callback is
3482 used: it isn't thread safe and the add_lock_callback should handle
3484 [Paul Rose <Paul.Rose@bridge.com>]
3486 *) Verify that incoming data obeys the block size in
3487 ssl3_enc (ssl/s3_enc.c) and tls1_enc (ssl/t1_enc.c).
3491 [Ulf Möller, Bodo Möller]
3493 *) The countermeasure against Bleichbacher's attack on PKCS #1 v1.5
3494 RSA encryption was accidentally removed in s3_srvr.c in OpenSSL 0.9.5
3495 when fixing the server behaviour for backwards-compatible 'client
3496 hello' messages. (Note that the attack is impractical against
3497 SSL 3.0 and TLS 1.0 anyway because length and version checking
3498 means that the probability of guessing a valid ciphertext is
3499 around 2^-40; see section 5 in Bleichenbacher's CRYPTO '98
3502 Before 0.9.5, the countermeasure (hide the error by generating a
3503 random 'decryption result') did not work properly because
3504 ERR_clear_error() was missing, meaning that SSL_get_error() would
3505 detect the supposedly ignored error.
3507 Both problems are now fixed.
3510 *) In crypto/bio/bf_buff.c, increase DEFAULT_BUFFER_SIZE to 4096
3511 (previously it was 1024).
3514 *) Fix for compatibility mode trust settings: ignore trust settings
3515 unless some valid trust or reject settings are present.
3518 *) Fix for blowfish EVP: its a variable length cipher.
3521 *) Fix various bugs related to DSA S/MIME verification. Handle missing
3522 parameters in DSA public key structures and return an error in the
3523 DSA routines if parameters are absent.
3526 *) In versions up to 0.9.6, RAND_file_name() resorted to file ".rnd"
3527 in the current directory if neither $RANDFILE nor $HOME was set.
3528 RAND_file_name() in 0.9.6a returned NULL in this case. This has
3529 caused some confusion to Windows users who haven't defined $HOME.
3530 Thus RAND_file_name() is changed again: e_os.h can define a
3531 DEFAULT_HOME, which will be used if $HOME is not set.
3532 For Windows, we use "C:"; on other platforms, we still require
3533 environment variables.
3535 *) Move 'if (!initialized) RAND_poll()' into regions protected by
3536 CRYPTO_LOCK_RAND. This is not strictly necessary, but avoids
3537 having multiple threads call RAND_poll() concurrently.
3540 *) In crypto/rand/md_rand.c, replace 'add_do_not_lock' flag by a
3541 combination of a flag and a thread ID variable.
3542 Otherwise while one thread is in ssleay_rand_bytes (which sets the
3543 flag), *other* threads can enter ssleay_add_bytes without obeying
3544 the CRYPTO_LOCK_RAND lock (and may even illegally release the lock
3545 that they do not hold after the first thread unsets add_do_not_lock).
3548 *) Change bctest again: '-x' expressions are not available in all
3552 Changes between 0.9.6 and 0.9.6a [5 Apr 2001]
3554 *) Fix a couple of memory leaks in PKCS7_dataDecode()
3555 [Steve Henson, reported by Heyun Zheng <hzheng@atdsprint.com>]
3557 *) Change Configure and Makefiles to provide EXE_EXT, which will contain
3558 the default extension for executables, if any. Also, make the perl
3559 scripts that use symlink() to test if it really exists and use "cp"
3560 if it doesn't. All this made OpenSSL compilable and installable in
3564 *) Fix for asn1_GetSequence() for indefinite length constructed data.
3565 If SEQUENCE is length is indefinite just set c->slen to the total
3566 amount of data available.
3567 [Steve Henson, reported by shige@FreeBSD.org]
3568 [This change does not apply to 0.9.7.]
3570 *) Change bctest to avoid here-documents inside command substitution
3571 (workaround for FreeBSD /bin/sh bug).
3572 For compatibility with Ultrix, avoid shell functions (introduced
3573 in the bctest version that searches along $PATH).
3576 *) Rename 'des_encrypt' to 'des_encrypt1'. This avoids the clashes
3577 with des_encrypt() defined on some operating systems, like Solaris
3581 *) Check the result of RSA-CRT (see D. Boneh, R. DeMillo, R. Lipton:
3582 On the Importance of Eliminating Errors in Cryptographic
3583 Computations, J. Cryptology 14 (2001) 2, 101-119,
3584 http://theory.stanford.edu/~dabo/papers/faults.ps.gz).
3587 *) MIPS assembler BIGNUM division bug fix.
3590 *) Disabled incorrect Alpha assembler code.
3593 *) Fix PKCS#7 decode routines so they correctly update the length
3594 after reading an EOC for the EXPLICIT tag.
