5 Changes between 0.9.6 and 0.9.7 [xx XXX 2001]
7 Both OpenSSL 0.9.6a (bugfix release, 5 Apr 2001) and OpenSSL 0.9.7
8 are based on OpenSSL 0.9.6.
9 Change log entries are tagged as follows:
10 -) applies to 0.9.6a (/0.9.6b) only
11 *) applies to 0.9.6a (/0.9.6b) and 0.9.7
12 +) applies to 0.9.7 only
14 *) Move 'if (!initialized) RAND_poll()' into regions protected by
15 CRYPTO_LOCK_RAND. This is not strictly necessary, but avoids
16 having multiple threads calling RAND_poll() concurrently.
19 *) In crypto/rand/md_rand.c, replace 'add_do_not_lock' flag by a
20 combination of a flag and a thread ID variable.
21 Otherwise while one thread is in ssleay_rand_bytes (which sets the
22 flag), *other* threads can enter ssleay_add_bytes without obeying
23 the CRYPTO_LOCK_RAND lock (and may even illegaly release the lock
24 that they do not hold after the first thread unsets add_do_not_lock).
27 +) Implement binary inversion algorithm for BN_mod_inverse in addition
28 to the algorithm using long divison. The binary algorithm can be
29 used only if the modulus is odd. On 32-bit systems, it is faster
30 only for relatively small moduli (roughly 20-30% for 128-bit moduli,
31 roughly 5-15% for 256-bit moduli), so we use it only for moduli
32 up to 450 bits. In 64-bit environments, the binary algorithm
33 appears to be advantageous for much longer moduli; here we use it
34 for moduli up to 2048 bits.
37 *) Change bctest again: '-x' expressions are not available in all
41 -) OpenSSL 0.9.6a released [5 Apr 2001]
43 *) Fix a couple of memory leaks in PKCS7_dataDecode()
44 [Steve Henson, reported by Heyun Zheng <hzheng@atdsprint.com>]
46 *) Change Configure and Makefiles to provide EXE_EXT, which will contain
47 the default extension for executables, if any. Also, make the perl
48 scripts that use symlink() to test if it really exists and use "cp"
49 if it doesn't. All this made OpenSSL compilable and installable in
53 +) Rewrite CHOICE field setting in ASN1_item_ex_d2i(). The old code
54 could not support the combine flag in choice fields.
57 -) Fix for asn1_GetSequence() for indefinite length constructed data.
58 If SEQUENCE is length is indefinite just set c->slen to the total
59 amount of data available.
60 [Steve Henson, reported by shige@FreeBSD.org]
61 [This change does not apply to 0.9.7.]
63 *) Change bctest to avoid here-documents inside command substitution
64 (workaround for FreeBSD /bin/sh bug).
65 For compatibility with Ultrix, avoid shell functions (introduced
66 in the bctest version that searches along $PATH).
69 *) Rename 'des_encrypt' to 'des_encrypt1'. This avoids the clashes
70 with des_encrypt() defined on some operating systems, like Solaris
74 *) Check the result of RSA-CRT (see D. Boneh, R. DeMillo, R. Lipton:
75 On the Importance of Eliminating Errors in Cryptographic
76 Computations, J. Cryptology 14 (2001) 2, 101-119,
77 http://theory.stanford.edu/~dabo/papers/faults.ps.gz).
80 *) MIPS assembler BIGNUM division bug fix.
83 *) Disabled incorrect Alpha assembler code.
86 -) Fix PKCS#7 decode routines so they correctly update the length
87 after reading an EOC for the EXPLICIT tag.
89 [This change does not apply to 0.9.7.]
91 *) Fix bug in PKCS#12 key generation routines. This was triggered
92 if a 3DES key was generated with a 0 initial byte. Include
93 PKCS12_BROKEN_KEYGEN compilation option to retain the old
94 (but broken) behaviour.
97 *) Enhance bctest to search for a working bc along $PATH and print
99 [Tim Rice <tim@multitalents.net> via Richard Levitte]
101 +) Add a 'copy_extensions' option to the 'ca' utility. This copies
102 extensions from a certificate request to the certificate.
105 +) Allow multiple 'certopt' and 'nameopt' options to be separated
106 by commas. Add 'namopt' and 'certopt' options to the 'ca' config
107 file: this allows the display of the certificate about to be
108 signed to be customised, to allow certain fields to be included
109 or excluded and extension details. The old system didn't display
110 multicharacter strings properly, omitted fields not in the policy
111 and couldn't display additional details such as extensions.
114 *) Fix memory leaks in err.c: free err_data string if necessary;
115 don't write to the wrong index in ERR_set_error_data.
118 +) Function EC_POINTs_mul for simultaneous scalar multiplication
119 of an arbitrary number of elliptic curve points, optionally
120 including the generator defined for the EC_GROUP.
121 EC_POINT_mul is a simple wrapper function for the typical case
122 that the point list has just one item (besides the optional
126 +) First EC_METHODs for curves over GF(p):
128 EC_GFp_simple_method() uses the basic BN_mod_mul and BN_mod_sqr
129 operations and provides various method functions that can also
130 operate with faster implementations of modular arithmetic.
132 EC_GFp_mont_method() reuses most functions that are part of
133 EC_GFp_simple_method, but uses Montgomery arithmetic.
135 [Bodo Moeller; point addition and point doubling
136 implementation directly derived from source code provided by
137 Lenka Fibikova <fibikova@exp-math.uni-essen.de>]
139 +) Framework for elliptic curves (crypto/ec/ec.h, crypto/ec/ec_lcl.h,
142 Curves are EC_GROUP objects (with an optional group generator)
143 based on EC_METHODs that are built into the library.
145 Points are EC_POINT objects based on EC_GROUP objects.
147 Most of the framework would be able to handle curves over arbitrary
148 finite fields, but as there are no obvious types for fields other
149 than GF(p), some functions are limited to that for now.
152 +) Add the -HTTP option to s_server. It is similar to -WWW, but requires
153 that the file contains a complete HTTP response.
156 +) Add the ec directory to mkdef.pl and mkfiles.pl. In mkdef.pl
157 change the def and num file printf format specifier from "%-40sXXX"
158 to "%-39s XXX". The latter will always guarantee a space after the
159 field while the former will cause them to run together if the field
160 is 40 of more characters long.
163 +) Constify the cipher and digest 'method' functions and structures
164 and modify related functions to take constant EVP_MD and EVP_CIPHER
168 *) Implement ssl23_peek (analogous to ssl23_read), which previously
172 *) Replace rdtsc with _emit statements for VC++ version 5.
173 [Jeremy Cooper <jeremy@baymoo.org>]
175 +) Hide BN_CTX structure details in bn_lcl.h instead of publishing them
176 in <openssl/bn.h>. Also further increase BN_CTX_NUM to 32.
179 +) Modify EVP_Digest*() routines so they now return values. Although the
180 internal software routines can never fail additional hardware versions
184 +) Clean up crypto/err/err.h and change some error codes to avoid conflicts:
186 Previously ERR_R_FATAL was too small and coincided with ERR_LIB_PKCS7
187 (= ERR_R_PKCS7_LIB); it is now 64 instead of 32.
190 ERR_R_NESTED_ASN1_ERROR
192 ERR_R_MISSING_ASN1_EOS
193 were 4 .. 9, conflicting with
194 ERR_LIB_RSA (= ERR_R_RSA_LIB)
196 ERR_LIB_PEM (= ERR_R_PEM_LIB).
197 They are now 58 .. 63 (i.e., just below ERR_R_FATAL).
199 Add new error code 'ERR_R_INTERNAL_ERROR'.
202 +) Don't overuse locks in crypto/err/err.c: For data retrieval, CRYPTO_r_lock
206 +) New option '-subj arg' for 'openssl req' and 'openssl ca'. This
207 sets the subject name for a new request or supersedes the
208 subject name in a given request. Formats that can be parsed are
209 'CN=Some Name, OU=myOU, C=IT'
211 'CN=Some Name/OU=myOU/C=IT'.
213 Add options '-batch' and '-verbose' to 'openssl req'.
214 [Massimiliano Pala <madwolf@hackmasters.net>]
216 *) Make it possible to reuse SSLv2 sessions.
219 +) Introduce the possibility to access global variables through
220 functions on platform were that's the best way to handle exporting
221 global variables in shared libraries. To enable this functionality,
222 one must configure with "EXPORT_VAR_AS_FN" or defined the C macro
223 "OPENSSL_EXPORT_VAR_AS_FUNCTION" in crypto/opensslconf.h (the latter
224 is normally done by Configure or something similar).
226 To implement a global variable, use the macro OPENSSL_IMPLEMENT_GLOBAL
227 in the source file (foo.c) like this:
229 OPENSSL_IMPLEMENT_GLOBAL(int,foo)=1;
230 OPENSSL_IMPLEMENT_GLOBAL(double,bar);
232 To declare a global variable, use the macros OPENSSL_DECLARE_GLOBAL
233 and OPENSSL_GLOBAL_REF in the header file (foo.h) like this:
235 OPENSSL_DECLARE_GLOBAL(int,foo);
236 #define foo OPENSSL_GLOBAL_REF(foo)
237 OPENSSL_DECLARE_GLOBAL(double,bar);
238 #define bar OPENSSL_GLOBAL_REF(bar)
240 The #defines are very important, and therefore so is including the
241 header file everywere where the defined globals are used.
243 The macro OPENSSL_EXPORT_VAR_AS_FUNCTION also affects the definition
244 of ASN.1 items, but that structure is a bt different.
246 The largest change is in util/mkdef.pl which has been enhanced with
247 better and easier to understand logic to choose which symbols should
248 go into the Windows .def files as well as a number of fixes and code
249 cleanup (among others, algorithm keywords are now sorted
250 lexicographically to avoid constant rewrites).
253 *) In copy_email() check for >= 0 as a return value for
254 X509_NAME_get_index_by_NID() since 0 is a valid index.
255 [Steve Henson reported by Massimiliano Pala <madwolf@opensca.org>]
257 +) In BN_div() keep a copy of the sign of 'num' before writing the
258 result to 'rm' because if rm==num the value will be overwritten
259 and produce the wrong result if 'num' is negative: this caused
260 problems with BN_mod() and BN_nnmod().
263 +) Function OCSP_request_verify(). This checks the signature on an
264 OCSP request and verifies the signer certificate. The signer
265 certificate is just checked for a generic purpose and OCSP request
269 +) Add OCSP_check_validity() function to check the validity of OCSP
270 responses. OCSP responses are prepared in real time and may only
271 be a few seconds old. Simply checking that the current time lies
272 between thisUpdate and nextUpdate max reject otherwise valid responses
273 caused by either OCSP responder or client clock innacuracy. Instead
274 we allow thisUpdate and nextUpdate to fall within a certain period of
275 the current time. The age of the response can also optionally be
276 checked. Two new options -validity_period and -status_age added to
280 +) If signature or public key algorithm is unrecognized print out its
281 OID rather that just UNKOWN.
284 *) Avoid coredump with unsupported or invalid public keys by checking if
285 X509_get_pubkey() fails in PKCS7_verify(). Fix memory leak when
286 PKCS7_verify() fails with non detached data.
289 +) Change OCSP_cert_to_id() to tolerate a NULL subject certificate and
290 OCSP_cert_id_new() a NULL serialNumber. This allows a partial certificate
291 ID to be generated from the issuer certificate alone which can then be
292 passed to OCSP_id_issuer_cmp().
295 +) New compilation option ASN1_ITEM_FUNCTIONS. This causes the new
296 ASN1 modules to export functions returning ASN1_ITEM pointers
297 instead of the ASN1_ITEM structures themselves. This adds several
298 new macros which allow the underlying ASN1 function/structure to
299 be accessed transparently. As a result code should not use ASN1_ITEM
300 references directly (such as &X509_it) but instead use the relevant
301 macros (such as ASN1_ITEM_rptr(X509)). This option is to allow
302 use of the new ASN1 code on platforms where exporting structures
303 is problematical (for example in shared libraries) but exporting
304 functions returning pointers to structures is not.
307 +) Add support for overriding the generation of SSL/TLS session IDs.
308 These callbacks can be registered either in an SSL_CTX or per SSL.
309 The purpose of this is to allow applications to control, if they wish,
310 the arbitrary values chosen for use as session IDs, particularly as it
311 can be useful for session caching in multiple-server environments. A
312 command-line switch for testing this (and any client code that wishes
313 to use such a feature) has been added to "s_server".
314 [Geoff Thorpe, Lutz Jaenicke]
316 +) Modify mkdef.pl to recognise and parse prprocessor conditionals
317 of the form '#if defined(...) || defined(...) || ...' and
318 '#if !defined(...) && !defined(...) && ...'. This also avoids
319 the growing number of special cases it was previously handling.
322 *) Don't use getenv in library functions when run as setuid/setgid.
323 New function OPENSSL_issetugid().
326 +) Make all configuration macros available for application by making
327 sure they are available in opensslconf.h, by giving them names starting
328 with "OPENSSL_" to avoid conflicts with other packages and by making
329 sure e_os2.h will cover all platform-specific cases together with
331 Additionally, it is now possible to define configuration/platform-
332 specific names (called "system identities"). In the C code, these
333 are prefixed with "OPENSSL_SYSNAME_". e_os2.h will create another
334 macro with the name beginning with "OPENSSL_SYS_", which is determined
335 from "OPENSSL_SYSNAME_*" or compiler-specific macros depending on
339 +) New option -set_serial to 'req' and 'x509' this allows the serial
340 number to use to be specified on the command line. Previously self
341 signed certificates were hard coded with serial number 0 and the
342 CA options of 'x509' had to use a serial number in a file which was
346 *) Avoid false positives in memory leak detection code (crypto/mem_dbg.c)
347 due to incorrect handling of multi-threading:
349 1. Fix timing glitch in the MemCheck_off() portion of CRYPTO_mem_ctrl().
351 2. Fix logical glitch in is_MemCheck_on() aka CRYPTO_is_mem_check_on().
353 3. Count how many times MemCheck_off() has been called so that
354 nested use can be treated correctly. This also avoids
355 inband-signalling in the previous code (which relied on the
356 assumption that thread ID 0 is impossible).
359 +) New options to 'ca' utility to support V2 CRL entry extensions.
360 Currently CRL reason, invalidity date and hold instruction are
361 supported. Add new CRL extensions to V3 code and some new objects.
364 *) Add "-rand" option also to s_client and s_server.
367 +) New function EVP_CIPHER_CTX_set_padding() this is used to
368 disable standard block padding (aka PKCS#5 padding) in the EVP
369 API, which was previously mandatory. This means that the data is
370 not padded in any way and so the total length much be a multiple
371 of the block size, otherwise an error occurs.
374 +) Initial (incomplete) OCSP SSL support.
377 *) Fix CPU detection on Irix 6.x.
378 [Kurt Hockenbury <khockenb@stevens-tech.edu> and
379 "Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
381 +) New function OCSP_parse_url(). This splits up a URL into its host,
382 port and path components: primarily to parse OCSP URLs. New -url
383 option to ocsp utility.
386 +) New nonce behavior. The return value of OCSP_check_nonce() now
387 reflects the various checks performed. Applications can decide
388 whether to tolerate certain situations such as an absent nonce
389 in a response when one was present in a request: the ocsp application
390 just prints out a warning. New function OCSP_add1_basic_nonce()
391 this is to allow responders to include a nonce in a response even if
392 the request is nonce-less.
395 *) Fix X509_NAME bug which produced incorrect encoding if X509_NAME
397 [This change does not apply to 0.9.7.]
399 *) Use the cached encoding of an X509_NAME structure rather than
400 copying it. This is apparently the reason for the libsafe "errors"
401 but the code is actually correct.
404 +) Disable stdin buffering in load_cert (apps/apps.c) so that no certs are
405 skipped when using openssl x509 multiple times on a single input file,
406 e.g. "(openssl x509 -out cert1; openssl x509 -out cert2) <certs".
409 +) Make ASN1_UTCTIME_set_string() and ASN1_GENERALIZEDTIME_set_string()
410 set string type: to handle setting ASN1_TIME structures. Fix ca
411 utility to correctly initialize revocation date of CRLs.
414 +) New option SSL_OP_CIPHER_SERVER_PREFERENCE allows the server to override
415 the clients preferred ciphersuites and rather use its own preferences.
416 Should help to work around M$ SGC (Server Gated Cryptography) bug in
417 Internet Explorer by ensuring unchanged hash method during stepup.
420 +) Make mkdef.pl recognise all DECLARE_ASN1 macros, change rijndael
421 to aes and add a new 'exist' option to print out symbols that don't
425 +) Additional options to ocsp utility to allow flags to be set and
426 additional certificates supplied.
429 +) Add the option -VAfile to 'openssl ocsp', so the user can give the
430 OCSP client a number of certificate to only verify the response
434 *) Add new function BN_rand_range(), and fix DSA_sign_setup() to prevent
435 Bleichenbacher's DSA attack.
436 Extend BN_[pseudo_]rand: As before, top=1 forces the highest two bits
437 to be set and top=0 forces the highest bit to be set; top=-1 is new
438 and leaves the highest bit random.
439 [Ulf Moeller, Bodo Moeller]
441 +) Update Rijndael code to version 3.0 and change EVP AES ciphers to
442 handle the new API. Currently only ECB, CBC modes supported. Add new
443 AES OIDs. Add TLS AES ciphersuites as described in the "AES Ciphersuites
444 for TLS" draft-ietf-tls-ciphersuite-03.txt.
445 [Ben Laurie, Steve Henson]
447 *) In the NCONF_...-based implementations for CONF_... queries
448 (crypto/conf/conf_lib.c), if the input LHASH is NULL, avoid using
449 a temporary CONF structure with the data component set to NULL
450 (which gives segmentation faults in lh_retrieve).
451 Instead, use NULL for the CONF pointer in CONF_get_string and
452 CONF_get_number (which may use environment variables) and directly
453 return NULL from CONF_get_section.
456 *) Fix potential buffer overrun for EBCDIC.
459 +) New function OCSP_copy_nonce() to copy nonce value (if present) from
463 +) Functions for OCSP responders. OCSP_request_onereq_count(),
464 OCSP_request_onereq_get0(), OCSP_onereq_get0_id() and OCSP_id_get0_info()
465 extract information from a certificate request. OCSP_response_create()
466 creates a response and optionally adds a basic response structure.
467 OCSP_basic_add1_status() adds a complete single response to a basic
468 reponse and returns the OCSP_SINGLERESP structure just added (to allow
469 extensions to be included for example). OCSP_basic_add1_cert() adds a
470 certificate to a basic response and OCSP_basic_sign() signs a basic
471 response with various flags. New helper functions ASN1_TIME_check()
472 (checks validity of ASN1_TIME structure) and ASN1_TIME_to_generalizedtime()
473 (converts ASN1_TIME to GeneralizedTime).
476 +) Various new functions. EVP_Digest() combines EVP_Digest{Init,Update,Final}()
477 in a single operation. X509_get0_pubkey_bitstr() extracts the public_key
478 structure from a certificate. X509_pubkey_digest() digests tha public_key
479 contents: this is used in various key identifiers.
482 *) Tolerate nonRepudiation as being valid for S/MIME signing and certSign
483 keyUsage if basicConstraints absent for a CA.
486 *) Make SMIME_write_PKCS7() write mail header values with a format that
487 is more generally accepted (no spaces before the semicolon), since
488 some programs can't parse those values properly otherwise. Also make
489 sure BIO's that break lines after each write do not create invalid
493 +) Make sk_sort() tolerate a NULL argument.
494 [Steve Henson reported by Massimiliano Pala <madwolf@comune.modena.it>]
496 +) New OCSP verify flag OCSP_TRUSTOTHER. When set the "other" certificates
497 passed by the function are trusted implicitly. If any of them signed the
498 reponse then it is assumed to be valid and is not verified.
501 -) Make the CRL encoding routines work with empty SEQUENCE OF. The
502 macros previously used would not encode an empty SEQUENCE OF
503 and break the signature.
505 [This change does not apply to 0.9.7.]
507 *) Zero the premaster secret after deriving the master secret in
511 +) In PKCS7_set_type() initialise content_type in PKCS7_ENC_CONTENT
512 to data. This was previously part of the PKCS7 ASN1 code. This
513 was causing problems with OpenSSL created PKCS#12 and PKCS#7 structures.
514 [Steve Henson, reported by Kenneth R. Robinette
515 <support@securenetterm.com>]
517 +) Add CRYPTO_push_info() and CRYPTO_pop_info() calls to new ASN1
518 routines: without these tracing memory leaks is very painful.
519 Fix leaks in PKCS12 and PKCS7 routines.
522 *) Add some EVP_add_digest_alias registrations (as found in
523 OpenSSL_add_all_digests()) to SSL_library_init()
524 aka OpenSSL_add_ssl_algorithms(). This provides improved
525 compatibility with peers using X.509 certificates
526 with unconventional AlgorithmIdentifier OIDs.
529 *) Fix for Irix with NO_ASM.
530 ["Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
532 *) ./config script fixes.
533 [Ulf Moeller, Richard Levitte]
535 +) Make X509_time_adj() cope with the new behaviour of ASN1_TIME_new().
536 Previously it initialised the 'type' argument to V_ASN1_UTCTIME which
537 effectively meant GeneralizedTime would never be used. Now it
538 is initialised to -1 but X509_time_adj() now has to check the value
539 and use ASN1_TIME_set() if the value is not V_ASN1_UTCTIME or
540 V_ASN1_GENERALIZEDTIME, without this it always uses GeneralizedTime.
541 [Steve Henson, reported by Kenneth R. Robinette
542 <support@securenetterm.com>]
544 +) Fixes to BN_to_ASN1_INTEGER when bn is zero. This would previously
545 result in a zero length in the ASN1_INTEGER structure which was
546 not consistent with the structure when d2i_ASN1_INTEGER() was used
547 and would cause ASN1_INTEGER_cmp() to fail. Enhance s2i_ASN1_INTEGER()
548 to cope with hex and negative integers. Fix bug in i2a_ASN1_INTEGER()
549 where it did not print out a minus for negative ASN1_INTEGER.
552 *) Fix 'openssl passwd -1'.
555 +) Add summary printout to ocsp utility. The various functions which
556 convert status values to strings have been renamed to:
557 OCSP_response_status_str(), OCSP_cert_status_str() and
558 OCSP_crl_reason_str() and are no longer static. New options
559 to verify nonce values and to disable verification. OCSP response
560 printout format cleaned up.
563 +) Add additional OCSP certificate checks. These are those specified
564 in RFC2560. This consists of two separate checks: the CA of the
565 certificate being checked must either be the OCSP signer certificate
566 or the issuer of the OCSP signer certificate. In the latter case the
567 OCSP signer certificate must contain the OCSP signing extended key
568 usage. This check is performed by attempting to match the OCSP
569 signer or the OCSP signer CA to the issuerNameHash and issuerKeyHash
570 in the OCSP_CERTID structures of the response.
573 +) Initial OCSP certificate verification added to OCSP_basic_verify()
574 and related routines. This uses the standard OpenSSL certificate
575 verify routines to perform initial checks (just CA validity) and
576 to obtain the certificate chain. Then additional checks will be
577 performed on the chain. Currently the root CA is checked to see
578 if it is explicitly trusted for OCSP signing. This is used to set
579 a root CA as a global signing root: that is any certificate that
580 chains to that CA is an acceptable OCSP signing certificate.
583 +) New '-extfile ...' option to 'openssl ca' for reading X.509v3
584 extensions from a separate configuration file.
585 As when reading extensions from the main configuration file,
586 the '-extensions ...' option may be used for specifying the
588 [Massimiliano Pala <madwolf@comune.modena.it>]
590 *) Change PKCS12_key_gen_asc() so it can cope with non null
591 terminated strings whose length is passed in the passlen
592 parameter, for example from PEM callbacks. This was done
593 by adding an extra length parameter to asc2uni().
594 [Steve Henson, reported by <oddissey@samsung.co.kr>]
596 +) New OCSP utility. Allows OCSP requests to be generated or
597 read. The request can be sent to a responder and the output
598 parsed, outputed or printed in text form. Not complete yet:
599 still needs to check the OCSP response validity.
602 +) New subcommands for 'openssl ca':
603 'openssl ca -status <serial>' prints the status of the cert with
604 the given serial number (according to the index file).
605 'openssl ca -updatedb' updates the expiry status of certificates
607 [Massimiliano Pala <madwolf@comune.modena.it>]
609 +) New '-newreq-nodes' command option to CA.pl. This is like
610 '-newreq', but calls 'openssl req' with the '-nodes' option
611 so that the resulting key is not encrypted.
612 [Damien Miller <djm@mindrot.org>]
614 +) New configuration for the GNU Hurd.
615 [Jonathan Bartlett <johnnyb@wolfram.com> via Richard Levitte]
617 +) Initial code to implement OCSP basic response verify. This
618 is currently incomplete. Currently just finds the signer's
619 certificate and verifies the signature on the response.
622 +) New SSLeay_version code SSLEAY_DIR to determine the compiled-in
623 value of OPENSSLDIR. This is available via the new '-d' option
624 to 'openssl version', and is also included in 'openssl version -a'.
627 *) Fix C code generated by 'openssl dsaparam -C': If a BN_bin2bn
628 call failed, free the DSA structure.
631 +) Allowing defining memory allocation callbacks that will be given
632 file name and line number information in additional arguments
633 (a const char* and an int). The basic functionality remains, as
634 well as the original possibility to just replace malloc(),
635 realloc() and free() by functions that do not know about these
636 additional arguments. To register and find out the current
637 settings for extended allocation functions, the following
638 functions are provided:
640 CRYPTO_set_mem_ex_functions
641 CRYPTO_set_locked_mem_ex_functions
642 CRYPTO_get_mem_ex_functions
643 CRYPTO_get_locked_mem_ex_functions
645 These work the same way as CRYPTO_set_mem_functions and friends.
646 CRYPTO_get_[locked_]mem_functions now writes 0 where such an
647 extended allocation function is enabled.
648 Similarly, CRYPTO_get_[locked_]mem_ex_functions writes 0 where
649 a conventional allocation function is enabled.
650 [Richard Levitte, Bodo Moeller]
652 *) Fix to uni2asc() to cope with zero length Unicode strings.
653 These are present in some PKCS#12 files.
656 +) Finish off removing the remaining LHASH function pointer casts.
657 There should no longer be any prototype-casting required when using
658 the LHASH abstraction, and any casts that remain are "bugs". See
659 the callback types and macros at the head of lhash.h for details
660 (and "OBJ_cleanup" in crypto/objects/obj_dat.c as an example).
663 +) Add automatic query of EGD sockets in RAND_poll() for the unix variant.
664 If an EGD or PRNGD is running and enough entropy is returned, automatic
665 seeding like with /dev/[u]random will be performed.
666 Positions tried are: /etc/entropy, /var/run/egd-pool.
669 +) Change the Unix RAND_poll() variant to be able to poll several
670 random devices, as specified by DEVRANDOM, until a sufficient amount
671 of data has been collected. We spend at most 10 ms on each file
672 (select timeout) and read in non-blocking mode. DEVRANDOM now
673 defaults to the list "/dev/urandom", "/dev/random", "/dev/srandom"
674 (previously it was just the string "/dev/urandom"), so on typical
675 platforms the 10 ms delay will never occur.
676 Also separate out the Unix variant to its own file, rand_unix.c.
677 For VMS, there's a currently-empty rand_vms.c.
680 +) Move OCSP client related routines to ocsp_cl.c. These
681 provide utility functions which an application needing
682 to issue a request to an OCSP responder and analyse the
683 response will typically need: as opposed to those which an
684 OCSP responder itself would need which will be added later.
686 OCSP_request_sign() signs an OCSP request with an API similar
687 to PKCS7_sign(). OCSP_response_status() returns status of OCSP
688 response. OCSP_response_get1_basic() extracts basic response
689 from response. OCSP_resp_find_status(): finds and extracts status
690 information from an OCSP_CERTID structure (which will be created
691 when the request structure is built). These are built from lower
692 level functions which work on OCSP_SINGLERESP structures but
693 wont normally be used unless the application wishes to examine
694 extensions in the OCSP response for example.
696 Replace nonce routines with a pair of functions.
697 OCSP_request_add1_nonce() adds a nonce value and optionally
698 generates a random value. OCSP_check_nonce() checks the
699 validity of the nonce in an OCSP response.
702 +) Change function OCSP_request_add() to OCSP_request_add0_id().
703 This doesn't copy the supplied OCSP_CERTID and avoids the
704 need to free up the newly created id. Change return type
705 to OCSP_ONEREQ to return the internal OCSP_ONEREQ structure.
706 This can then be used to add extensions to the request.
707 Deleted OCSP_request_new(), since most of its functionality
708 is now in OCSP_REQUEST_new() (and the case insensitive name
709 clash) apart from the ability to set the request name which
710 will be added elsewhere.
713 +) Update OCSP API. Remove obsolete extensions argument from
714 various functions. Extensions are now handled using the new
715 OCSP extension code. New simple OCSP HTTP function which
716 can be used to send requests and parse the response.
719 +) Fix the PKCS#7 (S/MIME) code to work with new ASN1. Two new
720 ASN1_ITEM structures help with sign and verify. PKCS7_ATTR_SIGN
721 uses the special reorder version of SET OF to sort the attributes
722 and reorder them to match the encoded order. This resolves a long
723 standing problem: a verify on a PKCS7 structure just after signing
724 it used to fail because the attribute order did not match the
725 encoded order. PKCS7_ATTR_VERIFY does not reorder the attributes:
726 it uses the received order. This is necessary to tolerate some broken
727 software that does not order SET OF. This is handled by encoding
728 as a SEQUENCE OF but using implicit tagging (with UNIVERSAL class)
729 to produce the required SET OF.
732 +) Have mk1mf.pl generate the macros OPENSSL_BUILD_SHLIBCRYPTO and
733 OPENSSL_BUILD_SHLIBSSL and use them appropriately in the header
734 files to get correct declarations of the ASN.1 item variables.
737 +) Rewrite of PKCS#12 code to use new ASN1 functionality. Replace many
738 PKCS#12 macros with real functions. Fix two unrelated ASN1 bugs:
739 asn1_check_tlen() would sometimes attempt to use 'ctx' when it was
740 NULL and ASN1_TYPE was not dereferenced properly in asn1_ex_c2i().
741 New ASN1 macro: DECLARE_ASN1_ITEM() which just declares the relevant
742 ASN1_ITEM and no wrapper functions.
745 +) New functions or ASN1_item_d2i_fp() and ASN1_item_d2i_bio(). These
746 replace the old function pointer based I/O routines. Change most of
747 the *_d2i_bio() and *_d2i_fp() functions to use these.
750 +) Enhance mkdef.pl to be more accepting about spacing in C preprocessor
751 lines, recognice more "algorithms" that can be deselected, and make
752 it complain about algorithm deselection that isn't recognised.
755 +) New ASN1 functions to handle dup, sign, verify, digest, pack and
756 unpack operations in terms of ASN1_ITEM. Modify existing wrappers
757 to use new functions. Add NO_ASN1_OLD which can be set to remove
758 some old style ASN1 functions: this can be used to determine if old
759 code will still work when these eventually go away.
762 +) New extension functions for OCSP structures, these follow the
763 same conventions as certificates and CRLs.
766 +) New function X509V3_add1_i2d(). This automatically encodes and
767 adds an extension. Its behaviour can be customised with various
768 flags to append, replace or delete. Various wrappers added for
769 certifcates and CRLs.
772 +) Fix to avoid calling the underlying ASN1 print routine when
773 an extension cannot be parsed. Correct a typo in the
774 OCSP_SERVICELOC extension. Tidy up print OCSP format.
777 *) Increase s2->wbuf allocation by one byte in ssl2_new (ssl/s2_lib.c).
778 Otherwise do_ssl_write (ssl/s2_pkt.c) will write beyond buffer limits
779 when writing a 32767 byte record.
780 [Bodo Moeller; problem reported by Eric Day <eday@concentric.net>]
782 *) In RSA_eay_public_{en,ed}crypt and RSA_eay_mod_exp (rsa_eay.c),
783 obtain lock CRYPTO_LOCK_RSA before setting rsa->_method_mod_{n,p,q}.
785 (RSA objects have a reference count access to which is protected
786 by CRYPTO_LOCK_RSA [see rsa_lib.c, s3_srvr.c, ssl_cert.c, ssl_rsa.c],
787 so they are meant to be shared between threads.)
788 [Bodo Moeller, Geoff Thorpe; original patch submitted by
789 "Reddie, Steven" <Steven.Reddie@ca.com>]
791 +) Make mkdef.pl parse some of the ASN1 macros and add apropriate
792 entries for variables.
795 *) Fix a deadlock in CRYPTO_mem_leaks().
798 +) Add functionality to apps/openssl.c for detecting locking
799 problems: As the program is single-threaded, all we have
800 to do is register a locking callback using an array for
801 storing which locks are currently held by the program.
804 +) Use a lock around the call to CRYPTO_get_ex_new_index() in
805 SSL_get_ex_data_X509_STORE_idx(), which is used in
806 ssl_verify_cert_chain() and thus can be called at any time
807 during TLS/SSL handshakes so that thread-safety is essential.
808 Unfortunately, the ex_data design is not at all suited
809 for multi-threaded use, so it probably should be abolished.
812 +) Added Broadcom "ubsec" ENGINE to OpenSSL.
813 [Broadcom, tweaked and integrated by Geoff Thorpe]
815 +) Move common extension printing code to new function
816 X509V3_print_extensions(). Reorganise OCSP print routines and
817 implement some needed OCSP ASN1 functions. Add OCSP extensions.
820 +) New function X509_signature_print() to remove duplication in some
824 +) Add a special meaning when SET OF and SEQUENCE OF flags are both
825 set (this was treated exactly the same as SET OF previously). This
826 is used to reorder the STACK representing the structure to match the
827 encoding. This will be used to get round a problem where a PKCS7
828 structure which was signed could not be verified because the STACK
829 order did not reflect the encoded order.
832 +) Reimplement the OCSP ASN1 module using the new code.
835 +) Update the X509V3 code to permit the use of an ASN1_ITEM structure
836 for its ASN1 operations. The old style function pointers still exist
837 for now but they will eventually go away.
840 +) Merge in replacement ASN1 code from the ASN1 branch. This almost
841 completely replaces the old ASN1 functionality with a table driven
842 encoder and decoder which interprets an ASN1_ITEM structure describing
843 the ASN1 module. Compatibility with the existing ASN1 API (i2d,d2i) is
844 largely maintained. Almost all of the old asn1_mac.h macro based ASN1
845 has also been converted to the new form.
848 +) Change BN_mod_exp_recp so that negative moduli are tolerated
849 (the sign is ignored). Similarly, ignore the sign in BN_MONT_CTX_set
850 so that BN_mod_exp_mont and BN_mod_exp_mont_word work
854 +) Fix BN_uadd and BN_usub: Always return non-negative results instead
855 of not touching the result's sign bit.
858 +) BN_div bugfix: If the result is 0, the sign (res->neg) must not be
862 +) Changed the LHASH code to use prototypes for callbacks, and created
863 macros to declare and implement thin (optionally static) functions
864 that provide type-safety and avoid function pointer casting for the
865 type-specific callbacks.
868 *) Use better test patterns in bntest.
871 +) Added Kerberos Cipher Suites to be used with TLS, as written in
873 [Veers Staats <staatsvr@asc.hpc.mil>,
874 Jeffrey Altman <jaltman@columbia.edu>, via Richard Levitte]
876 *) rand_win.c fix for Borland C.
879 *) BN_rshift bugfix for n == 0.
882 +) Reformat the FAQ so the different questions and answers can be divided
883 in sections depending on the subject.
886 +) Have the zlib compression code load ZLIB.DLL dynamically under
890 +) New function BN_mod_sqrt for computing square roots modulo a prime
891 (using the probabilistic Tonelli-Shanks algorithm unless
892 p == 3 (mod 4) or p == 5 (mod 8), which are cases that can
893 be handled deterministically).
894 [Lenka Fibikova <fibikova@exp-math.uni-essen.de>, Bodo Moeller]
896 *) Add a 'bctest' script that checks for some known 'bc' bugs
897 so that 'make test' does not abort just because 'bc' is broken.
900 *) Store verify_result within SSL_SESSION also for client side to
901 avoid potential security hole. (Re-used sessions on the client side
902 always resulted in verify_result==X509_V_OK, not using the original
903 result of the server certificate verification.)
906 +) Make BN_mod_inverse faster by explicitly handling small quotients
907 in the Euclid loop. (Speed gain about 20% for small moduli [256 or
908 512 bits], about 30% for larger ones [1024 or 2048 bits].)
911 *) Fix ssl3_pending: If the record in s->s3->rrec is not of type
912 SSL3_RT_APPLICATION_DATA, return 0.
913 Similarly, change ssl2_pending to return 0 if SSL_in_init(s) is true.
917 Both ssl2_peek and ssl3_peek, which were totally broken in earlier
918 releases, have been re-implemented by renaming the previous
919 implementations of ssl2_read and ssl3_read to ssl2_read_internal
920 and ssl3_read_internal, respectively, and adding 'peek' parameters
921 to them. The new ssl[23]_{read,peek} functions are calls to
922 ssl[23]_read_internal with the 'peek' flag set appropriately.
923 A 'peek' parameter has also been added to ssl3_read_bytes, which
924 does the actual work for ssl3_read_internal.
927 +) New function BN_kronecker.
930 +) Fix BN_gcd so that it works on negative inputs; the result is
931 positive unless both parameters are zero.
932 Previously something reasonably close to an infinite loop was
933 possible because numbers could be growing instead of shrinking
934 in the implementation of Euclid's algorithm.
937 +) Fix BN_is_word() and BN_is_one() macros to take into account the
938 sign of the number in question.
940 Fix BN_is_word(a,w) to work correctly for w == 0.
942 The old BN_is_word(a,w) macro is now called BN_abs_is_word(a,w)
943 because its test if the absolute value of 'a' equals 'w'.
944 Note that BN_abs_is_word does *not* handle w == 0 reliably;
945 it exists mostly for use in the implementations of BN_is_zero(),
946 BN_is_one(), and BN_is_word().
949 *) Initialise "ex_data" member of RSA/DSA/DH structures prior to calling
950 the method-specific "init()" handler. Also clean up ex_data after
951 calling the method-specific "finish()" handler. Previously, this was
952 happening the other way round.
955 +) New function BN_swap.
958 +) Use BN_nnmod instead of BN_mod in crypto/bn/bn_exp.c so that
959 the exponentiation functions are more likely to produce reasonable
960 results on negative inputs.
963 +) Change BN_mod_mul so that the result is always non-negative.
964 Previously, it could be negative if one of the factors was negative;
965 I don't think anyone really wanted that behaviour.
968 +) Move BN_mod_... functions into new file crypto/bn/bn_mod.c
969 (except for exponentiation, which stays in crypto/bn/bn_exp.c,
970 and BN_mod_mul_reciprocal, which stays in crypto/bn/bn_recp.c)
971 and add new functions:
984 These functions always generate non-negative results.
986 BN_nnmod otherwise is like BN_mod (if BN_mod computes a remainder r
987 such that |m| < r < 0, BN_nnmod will output rem + |m| instead).
989 BN_mod_XXX_quick(r, a, [b,] m) generates the same result as
990 BN_mod_XXX(r, a, [b,] m, ctx), but requires that a [and b]
992 [Lenka Fibikova <fibikova@exp-math.uni-essen.de>, Bodo Moeller]
994 +) Remove a few calls to bn_wexpand() in BN_sqr() (the one in there
995 was actually never needed) and in BN_mul(). The removal in BN_mul()
996 required a small change in bn_mul_part_recursive() and the addition
997 of the functions bn_cmp_part_words(), bn_sub_part_words() and
998 bn_add_part_words(), which do the same thing as bn_cmp_words(),
999 bn_sub_words() and bn_add_words() except they take arrays with
1003 +) In 'openssl passwd', verify passwords read from the terminal
1004 unless the '-salt' option is used (which usually means that
1005 verification would just waste user's time since the resulting
1006 hash is going to be compared with some given password hash)
1007 or the new '-noverify' option is used.
1009 This is an incompatible change, but it does not affect
1010 non-interactive use of 'openssl passwd' (passwords on the command
1011 line, '-stdin' option, '-in ...' option) and thus should not
1015 +) Remove all references to RSAref, since there's no more need for it.
1018 *) Increase BN_CTX_NUM (the number of BIGNUMs in a BN_CTX) to 16.
1019 The previous value, 12, was not always sufficient for BN_mod_exp().
1022 +) Make DSO load along a path given through an environment variable
1023 (SHLIB_PATH) with shl_load().
1026 +) Constify the ENGINE code as a result of BIGNUM constification.
1027 Also constify the RSA code and most things related to it. In a
1028 few places, most notable in the depth of the ASN.1 code, ugly
1029 casts back to non-const were required (to be solved at a later
1033 +) Make it so the openssl application has all engines loaded by default.
1036 +) Constify the BIGNUM routines a little more.
1039 *) Make sure that shared libraries get the internal name engine with
1040 the full version number and not just 0. This should mark the
1041 shared libraries as not backward compatible. Of course, this should
1042 be changed again when we can guarantee backward binary compatibility.
1045 +) Add the following functions:
1047 ENGINE_load_cswift()
1049 ENGINE_load_atalla()
1051 ENGINE_load_builtin_engines()
1053 That way, an application can itself choose if external engines that
1054 are built-in in OpenSSL shall ever be used or not. The benefit is
1055 that applications won't have to be linked with libdl or other dso
1056 libraries unless it's really needed.
1058 Changed 'openssl engine' to load all engines on demand.
1059 Changed the engine header files to avoid the duplication of some
1060 declarations (they differed!).
1063 +) 'openssl engine' can now list capabilities.
1066 +) Better error reporting in 'openssl engine'.
1069 +) Never call load_dh_param(NULL) in s_server.
1072 +) Add engine application. It can currently list engines by name and
1073 identity, and test if they are actually available.
1076 +) Add support for shared libraries under Irix.
1077 [Albert Chin-A-Young <china@thewrittenword.com>]
1079 +) Improve RPM specification file by forcing symbolic linking and making
1080 sure the installed documentation is also owned by root.root.
1081 [Damien Miller <djm@mindrot.org>]
1083 +) Add configuration option to build on Linux on both big-endian and
1085 [Ralf Baechle <ralf@uni-koblenz.de>]
1087 +) Give the OpenSSL applications more possibilities to make use of
1088 keys (public as well as private) handled by engines.
1091 +) Add OCSP code that comes from CertCo.
1094 +) Add VMS support for the Rijndael code.
1097 +) Added untested support for Nuron crypto accelerator.
1100 +) Add support for external cryptographic devices. This code was
1101 previously distributed separately as the "engine" branch.
1102 [Geoff Thorpe, Richard Levitte]
1104 +) Rework the filename-translation in the DSO code. It is now possible to
1105 have far greater control over how a "name" is turned into a filename
1106 depending on the operating environment and any oddities about the
1107 different shared library filenames on each system.
1110 +) Support threads on FreeBSD-elf in Configure.
1113 +) Add the possibility to create shared libraries on HP-UX
1116 +) Fix for SHA1 assembly problem with MASM: it produces
1117 warnings about corrupt line number information when assembling
1118 with debugging information. This is caused by the overlapping
1120 [Bernd Matthes <mainbug@celocom.de>, Steve Henson]
1123 NCONF_get_number() has no error checking at all. As a replacement,
1124 NCONF_get_number_e() is defined (_e for "error checking") and is
1125 promoted strongly. The old NCONF_get_number is kept around for
1126 binary backward compatibility.
1127 Make it possible for methods to load from something other than a BIO,
1128 by providing a function pointer that is given a name instead of a BIO.
1129 For example, this could be used to load configuration data from an
1133 *) Fix typo in get_cert_by_subject() in by_dir.c
1134 [Jean-Marc Desperrier <jean-marc.desperrier@certplus.com>]
1136 *) Rework the system to generate shared libraries:
1138 - Make note of the expected extension for the shared libraries and
1139 if there is a need for symbolic links from for example libcrypto.so.0
1140 to libcrypto.so.0.9.7. There is extended info in Configure for
1143 - Make as few rebuilds of the shared libraries as possible.
1145 - Still avoid linking the OpenSSL programs with the shared libraries.
1147 - When installing, install the shared libraries separately from the
1151 +) Fix for non blocking accept BIOs. Added new I/O special reason
1152 BIO_RR_ACCEPT to cover this case. Previously use of accept BIOs
1153 with non blocking I/O was not possible because no retry code was
1154 implemented. Also added new SSL code SSL_WANT_ACCEPT to cover
1158 +) Added the beginnings of Rijndael support.
1161 +) Fix for bug in DirectoryString mask setting. Add support for
1162 X509_NAME_print_ex() in 'req' and X509_print_ex() function
1163 to allow certificate printing to more controllable, additional
1164 'certopt' option to 'x509' to allow new printing options to be
1168 +) Clean old EAY MD5 hack from e_os.h.
1171 *) Fix SSL_CTX_set_read_ahead macro to actually use its argument.
1173 Copy SSL_CTX's read_ahead flag to SSL object directly in SSL_new
1174 and not in SSL_clear because the latter is also used by the
1175 accept/connect functions; previously, the settings made by
1176 SSL_set_read_ahead would be lost during the handshake.
1177 [Bodo Moeller; problems reported by Anders Gertz <gertz@epact.se>]
1179 *) Correct util/mkdef.pl to be selective about disabled algorithms.
1180 Previously, it would create entries for disableed algorithms no
1184 *) Added several new manual pages for SSL_* function.
1187 Changes between 0.9.5a and 0.9.6 [24 Sep 2000]
1189 *) In ssl23_get_client_hello, generate an error message when faced
1190 with an initial SSL 3.0/TLS record that is too small to contain the
1191 first two bytes of the ClientHello message, i.e. client_version.
1192 (Note that this is a pathologic case that probably has never happened
1193 in real life.) The previous approach was to use the version number
1194 from the record header as a substitute; but our protocol choice
1195 should not depend on that one because it is not authenticated
1196 by the Finished messages.
1199 *) More robust randomness gathering functions for Windows.
1200 [Jeffrey Altman <jaltman@columbia.edu>]
1202 *) For compatibility reasons if the flag X509_V_FLAG_ISSUER_CHECK is
1203 not set then we don't setup the error code for issuer check errors
1204 to avoid possibly overwriting other errors which the callback does
1205 handle. If an application does set the flag then we assume it knows
1206 what it is doing and can handle the new informational codes
1210 *) Fix for a nasty bug in ASN1_TYPE handling. ASN1_TYPE is used for
1211 a general "ANY" type, as such it should be able to decode anything
1212 including tagged types. However it didn't check the class so it would
1213 wrongly interpret tagged types in the same way as their universal
1214 counterpart and unknown types were just rejected. Changed so that the
1215 tagged and unknown types are handled in the same way as a SEQUENCE:
1216 that is the encoding is stored intact. There is also a new type
1217 "V_ASN1_OTHER" which is used when the class is not universal, in this
1218 case we have no idea what the actual type is so we just lump them all
1222 *) On VMS, stdout may very well lead to a file that is written to
1223 in a record-oriented fashion. That means that every write() will
1224 write a separate record, which will be read separately by the
1225 programs trying to read from it. This can be very confusing.
1227 The solution is to put a BIO filter in the way that will buffer
1228 text until a linefeed is reached, and then write everything a
1229 line at a time, so every record written will be an actual line,
1230 not chunks of lines and not (usually doesn't happen, but I've
1231 seen it once) several lines in one record. BIO_f_linebuffer() is
1234 Currently, it's a VMS-only method, because that's where it has
1235 been tested well enough.
1238 *) Remove 'optimized' squaring variant in BN_mod_mul_montgomery,
1239 it can return incorrect results.
1240 (Note: The buggy variant was not enabled in OpenSSL 0.9.5a,
1241 but it was in 0.9.6-beta[12].)
1244 *) Disable the check for content being present when verifying detached
1245 signatures in pk7_smime.c. Some versions of Netscape (wrongly)
1246 include zero length content when signing messages.
1249 *) New BIO_shutdown_wr macro, which invokes the BIO_C_SHUTDOWN_WR
1250 BIO_ctrl (for BIO pairs).
1253 *) Add DSO method for VMS.
1256 *) Bug fix: Montgomery multiplication could produce results with the
1260 *) Add RPM specification openssl.spec and modify it to build three
1261 packages. The default package contains applications, application
1262 documentation and run-time libraries. The devel package contains
1263 include files, static libraries and function documentation. The
1264 doc package contains the contents of the doc directory. The original
1265 openssl.spec was provided by Damien Miller <djm@mindrot.org>.
1268 *) Add a large number of documentation files for many SSL routines.
1269 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
1271 *) Add a configuration entry for Sony News 4.
1272 [NAKAJI Hiroyuki <nakaji@tutrp.tut.ac.jp>]
1274 *) Don't set the two most significant bits to one when generating a
1275 random number < q in the DSA library.
1278 *) New SSL API mode 'SSL_MODE_AUTO_RETRY'. This disables the default
1279 behaviour that SSL_read may result in SSL_ERROR_WANT_READ (even if
1280 the underlying transport is blocking) if a handshake took place.
1281 (The default behaviour is needed by applications such as s_client
1282 and s_server that use select() to determine when to use SSL_read;
1283 but for applications that know in advance when to expect data, it
1284 just makes things more complicated.)
1287 *) Add RAND_egd_bytes(), which gives control over the number of bytes read
1291 *) Add a few more EBCDIC conditionals that make `req' and `x509'
1292 work better on such systems.
1293 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
1295 *) Add two demo programs for PKCS12_parse() and PKCS12_create().
1296 Update PKCS12_parse() so it copies the friendlyName and the
1297 keyid to the certificates aux info.
1300 *) Fix bug in PKCS7_verify() which caused an infinite loop
1301 if there was more than one signature.
1302 [Sven Uszpelkat <su@celocom.de>]
1304 *) Major change in util/mkdef.pl to include extra information
1305 about each symbol, as well as presentig variables as well
1306 as functions. This change means that there's n more need
1307 to rebuild the .num files when some algorithms are excluded.
1310 *) Allow the verify time to be set by an application,
1311 rather than always using the current time.
1314 *) Phase 2 verify code reorganisation. The certificate
1315 verify code now looks up an issuer certificate by a
1316 number of criteria: subject name, authority key id
1317 and key usage. It also verifies self signed certificates
1318 by the same criteria. The main comparison function is
1319 X509_check_issued() which performs these checks.
1321 Lot of changes were necessary in order to support this
1322 without completely rewriting the lookup code.
1324 Authority and subject key identifier are now cached.
1326 The LHASH 'certs' is X509_STORE has now been replaced
1327 by a STACK_OF(X509_OBJECT). This is mainly because an
1328 LHASH can't store or retrieve multiple objects with
1329 the same hash value.
1331 As a result various functions (which were all internal
1332 use only) have changed to handle the new X509_STORE
1333 structure. This will break anything that messed round
1334 with X509_STORE internally.
1336 The functions X509_STORE_add_cert() now checks for an
1337 exact match, rather than just subject name.
1339 The X509_STORE API doesn't directly support the retrieval
1340 of multiple certificates matching a given criteria, however
1341 this can be worked round by performing a lookup first
1342 (which will fill the cache with candidate certificates)
1343 and then examining the cache for matches. This is probably
1344 the best we can do without throwing out X509_LOOKUP
1345 entirely (maybe later...).
1347 The X509_VERIFY_CTX structure has been enhanced considerably.
1349 All certificate lookup operations now go via a get_issuer()
1350 callback. Although this currently uses an X509_STORE it
1351 can be replaced by custom lookups. This is a simple way
1352 to bypass the X509_STORE hackery necessary to make this
1353 work and makes it possible to use more efficient techniques
1354 in future. A very simple version which uses a simple
1355 STACK for its trusted certificate store is also provided
1356 using X509_STORE_CTX_trusted_stack().
1358 The verify_cb() and verify() callbacks now have equivalents
1359 in the X509_STORE_CTX structure.
1361 X509_STORE_CTX also has a 'flags' field which can be used
1362 to customise the verify behaviour.
1365 *) Add new PKCS#7 signing option PKCS7_NOSMIMECAP which
1366 excludes S/MIME capabilities.
1369 *) When a certificate request is read in keep a copy of the
1370 original encoding of the signed data and use it when outputing
1371 again. Signatures then use the original encoding rather than
1372 a decoded, encoded version which may cause problems if the
1373 request is improperly encoded.
1376 *) For consistency with other BIO_puts implementations, call
1377 buffer_write(b, ...) directly in buffer_puts instead of calling
1380 In BIO_puts, increment b->num_write as in BIO_write.
1381 [Peter.Sylvester@EdelWeb.fr]
1383 *) Fix BN_mul_word for the case where the word is 0. (We have to use
1384 BN_zero, we may not return a BIGNUM with an array consisting of
1388 *) Avoid calling abort() from within the library when problems are
1389 detected, except if preprocessor symbols have been defined
1390 (such as REF_CHECK, BN_DEBUG etc.).
1393 *) New openssl application 'rsautl'. This utility can be
1394 used for low level RSA operations. DER public key
1395 BIO/fp routines also added.
1398 *) New Configure entry and patches for compiling on QNX 4.
1399 [Andreas Schneider <andreas@ds3.etech.fh-hamburg.de>]
1401 *) A demo state-machine implementation was sponsored by
1402 Nuron (http://www.nuron.com/) and is now available in
1403 demos/state_machine.
1406 *) New options added to the 'dgst' utility for signature
1407 generation and verification.
1410 *) Unrecognized PKCS#7 content types are now handled via a
1411 catch all ASN1_TYPE structure. This allows unsupported
1412 types to be stored as a "blob" and an application can
1413 encode and decode it manually.
1416 *) Fix various signed/unsigned issues to make a_strex.c
1418 [Oscar Jacobsson <oscar.jacobsson@celocom.com>]
1420 *) ASN1 fixes. i2d_ASN1_OBJECT was not returning the correct
1421 length if passed a buffer. ASN1_INTEGER_to_BN failed
1422 if passed a NULL BN and its argument was negative.
1423 [Steve Henson, pointed out by Sven Heiberg <sven@tartu.cyber.ee>]
1425 *) Modification to PKCS#7 encoding routines to output definite
1426 length encoding. Since currently the whole structures are in
1427 memory there's not real point in using indefinite length
1428 constructed encoding. However if OpenSSL is compiled with
1429 the flag PKCS7_INDEFINITE_ENCODING the old form is used.
1432 *) Added BIO_vprintf() and BIO_vsnprintf().
1435 *) Added more prefixes to parse for in the the strings written
1436 through a logging bio, to cover all the levels that are available
1437 through syslog. The prefixes are now:
1439 PANIC, EMERG, EMR => LOG_EMERG
1440 ALERT, ALR => LOG_ALERT
1441 CRIT, CRI => LOG_CRIT
1442 ERROR, ERR => LOG_ERR
1443 WARNING, WARN, WAR => LOG_WARNING
1444 NOTICE, NOTE, NOT => LOG_NOTICE
1445 INFO, INF => LOG_INFO
1446 DEBUG, DBG => LOG_DEBUG
1448 and as before, if none of those prefixes are present at the
1449 beginning of the string, LOG_ERR is chosen.
1451 On Win32, the LOG_* levels are mapped according to this:
1453 LOG_EMERG, LOG_ALERT, LOG_CRIT, LOG_ERR => EVENTLOG_ERROR_TYPE
1454 LOG_WARNING => EVENTLOG_WARNING_TYPE
1455 LOG_NOTICE, LOG_INFO, LOG_DEBUG => EVENTLOG_INFORMATION_TYPE
1459 *) Made it possible to reconfigure with just the configuration
1460 argument "reconf" or "reconfigure". The command line arguments
1461 are stored in Makefile.ssl in the variable CONFIGURE_ARGS,
1462 and are retrieved from there when reconfiguring.
1466 [Assar Westerlund <assar@sics.se>, Richard Levitte]
1468 *) Add the arguments -CAfile and -CApath to the pkcs12 utility.
1471 *) The obj_dat.pl script was messing up the sorting of object
1472 names. The reason was that it compared the quoted version
1473 of strings as a result "OCSP" > "OCSP Signing" because
1474 " > SPACE. Changed script to store unquoted versions of
1475 names and add quotes on output. It was also omitting some
1476 names from the lookup table if they were given a default
1477 value (that is if SN is missing it is given the same
1478 value as LN and vice versa), these are now added on the
1479 grounds that if an object has a name we should be able to
1480 look it up. Finally added warning output when duplicate
1481 short or long names are found.
1484 *) Changes needed for Tandem NSK.
1485 [Scott Uroff <scott@xypro.com>]
1487 *) Fix SSL 2.0 rollback checking: Due to an off-by-one error in
1488 RSA_padding_check_SSLv23(), special padding was never detected
1489 and thus the SSL 3.0/TLS 1.0 countermeasure against protocol
1490 version rollback attacks was not effective.
1492 In s23_clnt.c, don't use special rollback-attack detection padding
1493 (RSA_SSLV23_PADDING) if SSL 2.0 is the only protocol enabled in the
1494 client; similarly, in s23_srvr.c, don't do the rollback check if
1495 SSL 2.0 is the only protocol enabled in the server.
1498 *) Make it possible to get hexdumps of unprintable data with 'openssl
1499 asn1parse'. By implication, the functions ASN1_parse_dump() and
1500 BIO_dump_indent() are added.
1503 *) New functions ASN1_STRING_print_ex() and X509_NAME_print_ex()
1504 these print out strings and name structures based on various
1505 flags including RFC2253 support and proper handling of
1506 multibyte characters. Added options to the 'x509' utility
1507 to allow the various flags to be set.
1510 *) Various fixes to use ASN1_TIME instead of ASN1_UTCTIME.
1511 Also change the functions X509_cmp_current_time() and
1512 X509_gmtime_adj() work with an ASN1_TIME structure,
1513 this will enable certificates using GeneralizedTime in validity
1514 dates to be checked.
1517 *) Make the NEG_PUBKEY_BUG code (which tolerates invalid
1518 negative public key encodings) on by default,
1519 NO_NEG_PUBKEY_BUG can be set to disable it.
1522 *) New function c2i_ASN1_OBJECT() which acts on ASN1_OBJECT
1523 content octets. An i2c_ASN1_OBJECT is unnecessary because
1524 the encoding can be trivially obtained from the structure.
1527 *) crypto/err.c locking bugfix: Use write locks (CRYPTO_w_[un]lock),
1528 not read locks (CRYPTO_r_[un]lock).
1531 *) A first attempt at creating official support for shared
1532 libraries through configuration. I've kept it so the
1533 default is static libraries only, and the OpenSSL programs
1534 are always statically linked for now, but there are
1535 preparations for dynamic linking in place.
1536 This has been tested on Linux and True64.
1539 *) Randomness polling function for Win9x, as described in:
1540 Peter Gutmann, Software Generation of Practically Strong
1544 *) Fix so PRNG is seeded in req if using an already existing
1548 *) New options to smime application. -inform and -outform
1549 allow alternative formats for the S/MIME message including
1550 PEM and DER. The -content option allows the content to be
1551 specified separately. This should allow things like Netscape
1552 form signing output easier to verify.
1555 *) Fix the ASN1 encoding of tags using the 'long form'.
1558 *) New ASN1 functions, i2c_* and c2i_* for INTEGER and BIT
1559 STRING types. These convert content octets to and from the
1560 underlying type. The actual tag and length octets are
1561 already assumed to have been read in and checked. These
1562 are needed because all other string types have virtually
1563 identical handling apart from the tag. By having versions
1564 of the ASN1 functions that just operate on content octets
1565 IMPLICIT tagging can be handled properly. It also allows
1566 the ASN1_ENUMERATED code to be cut down because ASN1_ENUMERATED
1567 and ASN1_INTEGER are identical apart from the tag.
1570 *) Change the handling of OID objects as follows:
1572 - New object identifiers are inserted in objects.txt, following
1573 the syntax given in objects.README.
1574 - objects.pl is used to process obj_mac.num and create a new
1576 - obj_dat.pl is used to create a new obj_dat.h, using the data in
1579 This is currently kind of a hack, and the perl code in objects.pl
1580 isn't very elegant, but it works as I intended. The simplest way
1581 to check that it worked correctly is to look in obj_dat.h and
1582 check the array nid_objs and make sure the objects haven't moved
1583 around (this is important!). Additions are OK, as well as
1584 consistent name changes.
1587 *) Add BSD-style MD5-based passwords to 'openssl passwd' (option '-1').
1590 *) Addition of the command line parameter '-rand file' to 'openssl req'.
1591 The given file adds to whatever has already been seeded into the
1592 random pool through the RANDFILE configuration file option or
1593 environment variable, or the default random state file.
1596 *) mkstack.pl now sorts each macro group into lexical order.
1597 Previously the output order depended on the order the files
1598 appeared in the directory, resulting in needless rewriting
1602 *) Patches to make OpenSSL compile under Win32 again. Mostly
1603 work arounds for the VC++ problem that it treats func() as
1604 func(void). Also stripped out the parts of mkdef.pl that
1605 added extra typesafe functions: these no longer exist.
1608 *) Reorganisation of the stack code. The macros are now all
1609 collected in safestack.h . Each macro is defined in terms of
1610 a "stack macro" of the form SKM_<name>(type, a, b). The
1611 DEBUG_SAFESTACK is now handled in terms of function casts,
1612 this has the advantage of retaining type safety without the
1613 use of additional functions. If DEBUG_SAFESTACK is not defined
1614 then the non typesafe macros are used instead. Also modified the
1615 mkstack.pl script to handle the new form. Needs testing to see
1616 if which (if any) compilers it chokes and maybe make DEBUG_SAFESTACK
1617 the default if no major problems. Similar behaviour for ASN1_SET_OF
1618 and PKCS12_STACK_OF.
1621 *) When some versions of IIS use the 'NET' form of private key the
1622 key derivation algorithm is different. Normally MD5(password) is
1623 used as a 128 bit RC4 key. In the modified case
1624 MD5(MD5(password) + "SGCKEYSALT") is used insted. Added some
1625 new functions i2d_RSA_NET(), d2i_RSA_NET() etc which are the same
1626 as the old Netscape_RSA functions except they have an additional
1627 'sgckey' parameter which uses the modified algorithm. Also added
1628 an -sgckey command line option to the rsa utility. Thanks to
1629 Adrian Peck <bertie@ncipher.com> for posting details of the modified
1630 algorithm to openssl-dev.
1633 *) The evp_local.h macros were using 'c.##kname' which resulted in
1634 invalid expansion on some systems (SCO 5.0.5 for example).
1635 Corrected to 'c.kname'.
1636 [Phillip Porch <root@theporch.com>]
1638 *) New X509_get1_email() and X509_REQ_get1_email() functions that return
1639 a STACK of email addresses from a certificate or request, these look
1640 in the subject name and the subject alternative name extensions and
1641 omit any duplicate addresses.
1644 *) Re-implement BN_mod_exp2_mont using independent (and larger) windows.
1645 This makes DSA verification about 2 % faster.
1648 *) Increase maximum window size in BN_mod_exp_... to 6 bits instead of 5
1649 (meaning that now 2^5 values will be precomputed, which is only 4 KB
1650 plus overhead for 1024 bit moduli).
1651 This makes exponentiations about 0.5 % faster for 1024 bit
1652 exponents (as measured by "openssl speed rsa2048").
1655 *) Rename memory handling macros to avoid conflicts with other
1657 Malloc => OPENSSL_malloc
1658 Malloc_locked => OPENSSL_malloc_locked
1659 Realloc => OPENSSL_realloc
1660 Free => OPENSSL_free
1663 *) New function BN_mod_exp_mont_word for small bases (roughly 15%
1664 faster than BN_mod_exp_mont, i.e. 7% for a full DH exchange).
1667 *) CygWin32 support.
1668 [John Jarvie <jjarvie@newsguy.com>]
1670 *) The type-safe stack code has been rejigged. It is now only compiled
1671 in when OpenSSL is configured with the DEBUG_SAFESTACK option and
1672 by default all type-specific stack functions are "#define"d back to
1673 standard stack functions. This results in more streamlined output
1674 but retains the type-safety checking possibilities of the original
1678 *) The STACK code has been cleaned up, and certain type declarations
1679 that didn't make a lot of sense have been brought in line. This has
1680 also involved a cleanup of sorts in safestack.h to more correctly
1681 map type-safe stack functions onto their plain stack counterparts.
1682 This work has also resulted in a variety of "const"ifications of
1683 lots of the code, especially "_cmp" operations which should normally
1684 be prototyped with "const" parameters anyway.
1687 *) When generating bytes for the first time in md_rand.c, 'stir the pool'
1688 by seeding with STATE_SIZE dummy bytes (with zero entropy count).
1689 (The PRNG state consists of two parts, the large pool 'state' and 'md',
1690 where all of 'md' is used each time the PRNG is used, but 'state'
1691 is used only indexed by a cyclic counter. As entropy may not be
1692 well distributed from the beginning, 'md' is important as a
1693 chaining variable. However, the output function chains only half
1694 of 'md', i.e. 80 bits. ssleay_rand_add, on the other hand, chains
1695 all of 'md', and seeding with STATE_SIZE dummy bytes will result
1696 in all of 'state' being rewritten, with the new values depending
1697 on virtually all of 'md'. This overcomes the 80 bit limitation.)
1700 *) In ssl/s2_clnt.c and ssl/s3_clnt.c, call ERR_clear_error() when
1701 the handshake is continued after ssl_verify_cert_chain();
1702 otherwise, if SSL_VERIFY_NONE is set, remaining error codes
1703 can lead to 'unexplainable' connection aborts later.
1704 [Bodo Moeller; problem tracked down by Lutz Jaenicke]
1706 *) Major EVP API cipher revision.
1707 Add hooks for extra EVP features. This allows various cipher
1708 parameters to be set in the EVP interface. Support added for variable
1709 key length ciphers via the EVP_CIPHER_CTX_set_key_length() function and
1710 setting of RC2 and RC5 parameters.
1712 Modify EVP_OpenInit() and EVP_SealInit() to cope with variable key length
1715 Remove lots of duplicated code from the EVP library. For example *every*
1716 cipher init() function handles the 'iv' in the same way according to the
1717 cipher mode. They also all do nothing if the 'key' parameter is NULL and
1718 for CFB and OFB modes they zero ctx->num.
1720 New functionality allows removal of S/MIME code RC2 hack.
1722 Most of the routines have the same form and so can be declared in terms
1725 By shifting this to the top level EVP_CipherInit() it can be removed from
1726 all individual ciphers. If the cipher wants to handle IVs or keys
1727 differently it can set the EVP_CIPH_CUSTOM_IV or EVP_CIPH_ALWAYS_CALL_INIT
1730 Change lots of functions like EVP_EncryptUpdate() to now return a
1731 value: although software versions of the algorithms cannot fail
1732 any installed hardware versions can.
1735 *) Implement SSL_OP_TLS_ROLLBACK_BUG: In ssl3_get_client_key_exchange, if
1736 this option is set, tolerate broken clients that send the negotiated
1737 protocol version number instead of the requested protocol version
1741 *) Call dh_tmp_cb (set by ..._TMP_DH_CB) with correct 'is_export' flag;
1742 i.e. non-zero for export ciphersuites, zero otherwise.
1743 Previous versions had this flag inverted, inconsistent with
1744 rsa_tmp_cb (..._TMP_RSA_CB).
1745 [Bodo Moeller; problem reported by Amit Chopra]
1747 *) Add missing DSA library text string. Work around for some IIS
1748 key files with invalid SEQUENCE encoding.
1751 *) Add a document (doc/standards.txt) that list all kinds of standards
1752 and so on that are implemented in OpenSSL.
1755 *) Enhance c_rehash script. Old version would mishandle certificates
1756 with the same subject name hash and wouldn't handle CRLs at all.
1757 Added -fingerprint option to crl utility, to support new c_rehash
1761 *) Eliminate non-ANSI declarations in crypto.h and stack.h.
1764 *) Fix for SSL server purpose checking. Server checking was
1765 rejecting certificates which had extended key usage present
1766 but no ssl client purpose.
1767 [Steve Henson, reported by Rene Grosser <grosser@hisolutions.com>]
1769 *) Make PKCS#12 code work with no password. The PKCS#12 spec
1770 is a little unclear about how a blank password is handled.
1771 Since the password in encoded as a BMPString with terminating
1772 double NULL a zero length password would end up as just the
1773 double NULL. However no password at all is different and is
1774 handled differently in the PKCS#12 key generation code. NS
1775 treats a blank password as zero length. MSIE treats it as no
1776 password on export: but it will try both on import. We now do
1777 the same: PKCS12_parse() tries zero length and no password if
1778 the password is set to "" or NULL (NULL is now a valid password:
1779 it wasn't before) as does the pkcs12 application.
1782 *) Bugfixes in apps/x509.c: Avoid a memory leak; and don't use
1783 perror when PEM_read_bio_X509_REQ fails, the error message must
1784 be obtained from the error queue.
1787 *) Avoid 'thread_hash' memory leak in crypto/err/err.c by freeing
1788 it in ERR_remove_state if appropriate, and change ERR_get_state
1789 accordingly to avoid race conditions (this is necessary because
1790 thread_hash is no longer constant once set).
1793 *) Bugfix for linux-elf makefile.one.
1796 *) RSA_get_default_method() will now cause a default
1797 RSA_METHOD to be chosen if one doesn't exist already.
1798 Previously this was only set during a call to RSA_new()
1799 or RSA_new_method(NULL) meaning it was possible for
1800 RSA_get_default_method() to return NULL.
1803 *) Added native name translation to the existing DSO code
1804 that will convert (if the flag to do so is set) filenames
1805 that are sufficiently small and have no path information
1806 into a canonical native form. Eg. "blah" converted to
1807 "libblah.so" or "blah.dll" etc.
1810 *) New function ERR_error_string_n(e, buf, len) which is like
1811 ERR_error_string(e, buf), but writes at most 'len' bytes
1812 including the 0 terminator. For ERR_error_string_n, 'buf'
1814 [Damien Miller <djm@mindrot.org>, Bodo Moeller]
1816 *) CONF library reworked to become more general. A new CONF
1817 configuration file reader "class" is implemented as well as a
1818 new functions (NCONF_*, for "New CONF") to handle it. The now
1819 old CONF_* functions are still there, but are reimplemented to
1820 work in terms of the new functions. Also, a set of functions
1821 to handle the internal storage of the configuration data is
1822 provided to make it easier to write new configuration file
1823 reader "classes" (I can definitely see something reading a
1824 configuration file in XML format, for example), called _CONF_*,
1825 or "the configuration storage API"...
1827 The new configuration file reading functions are:
1829 NCONF_new, NCONF_free, NCONF_load, NCONF_load_fp, NCONF_load_bio,
1830 NCONF_get_section, NCONF_get_string, NCONF_get_numbre
1832 NCONF_default, NCONF_WIN32
1834 NCONF_dump_fp, NCONF_dump_bio
1836 NCONF_default and NCONF_WIN32 are method (or "class") choosers,
1837 NCONF_new creates a new CONF object. This works in the same way
1838 as other interfaces in OpenSSL, like the BIO interface.
1839 NCONF_dump_* dump the internal storage of the configuration file,
1840 which is useful for debugging. All other functions take the same
1841 arguments as the old CONF_* functions wth the exception of the
1842 first that must be a `CONF *' instead of a `LHASH *'.
1844 To make it easer to use the new classes with the old CONF_* functions,
1845 the function CONF_set_default_method is provided.
1848 *) Add '-tls1' option to 'openssl ciphers', which was already
1849 mentioned in the documentation but had not been implemented.
1850 (This option is not yet really useful because even the additional
1851 experimental TLS 1.0 ciphers are currently treated as SSL 3.0 ciphers.)
1854 *) Initial DSO code added into libcrypto for letting OpenSSL (and
1855 OpenSSL-based applications) load shared libraries and bind to
1856 them in a portable way.
1857 [Geoff Thorpe, with contributions from Richard Levitte]
1859 Changes between 0.9.5 and 0.9.5a [1 Apr 2000]
1861 *) Make sure _lrotl and _lrotr are only used with MSVC.
1863 *) Use lock CRYPTO_LOCK_RAND correctly in ssleay_rand_status
1864 (the default implementation of RAND_status).
1866 *) Rename openssl x509 option '-crlext', which was added in 0.9.5,
1867 to '-clrext' (= clear extensions), as intended and documented.
1868 [Bodo Moeller; inconsistency pointed out by Michael Attili
1871 *) Fix for HMAC. It wasn't zeroing the rest of the block if the key length
1872 was larger than the MD block size.
1873 [Steve Henson, pointed out by Yost William <YostW@tce.com>]
1875 *) Modernise PKCS12_parse() so it uses STACK_OF(X509) for its ca argument
1876 fix a leak when the ca argument was passed as NULL. Stop X509_PUBKEY_set()
1877 using the passed key: if the passed key was a private key the result
1878 of X509_print(), for example, would be to print out all the private key
1882 *) des_quad_cksum() byte order bug fix.
1883 [Ulf Möller, using the problem description in krb4-0.9.7, where
1884 the solution is attributed to Derrick J Brashear <shadow@DEMENTIA.ORG>]
1886 *) Fix so V_ASN1_APP_CHOOSE works again: however its use is strongly
1888 [Steve Henson, pointed out by Brian Korver <briank@cs.stanford.edu>]
1890 *) For easily testing in shell scripts whether some command
1891 'openssl XXX' exists, the new pseudo-command 'openssl no-XXX'
1892 returns with exit code 0 iff no command of the given name is available.
1893 'no-XXX' is printed in this case, 'XXX' otherwise. In both cases,
1894 the output goes to stdout and nothing is printed to stderr.
1895 Additional arguments are always ignored.
1897 Since for each cipher there is a command of the same name,
1898 the 'no-cipher' compilation switches can be tested this way.
1900 ('openssl no-XXX' is not able to detect pseudo-commands such
1901 as 'quit', 'list-XXX-commands', or 'no-XXX' itself.)
1904 *) Update test suite so that 'make test' succeeds in 'no-rsa' configuration.
1907 *) For SSL_[CTX_]set_tmp_dh, don't create a DH key if SSL_OP_SINGLE_DH_USE
1908 is set; it will be thrown away anyway because each handshake creates
1910 ssl_cert_dup, which is used by SSL_new, now copies DH keys in addition
1911 to parameters -- in previous versions (since OpenSSL 0.9.3) the
1912 'default key' from SSL_CTX_set_tmp_dh would always be lost, meanining
1913 you effectivly got SSL_OP_SINGLE_DH_USE when using this macro.
1916 *) New s_client option -ign_eof: EOF at stdin is ignored, and
1917 'Q' and 'R' lose their special meanings (quit/renegotiate).
1918 This is part of what -quiet does; unlike -quiet, -ign_eof
1919 does not suppress any output.
1922 *) Add compatibility options to the purpose and trust code. The
1923 purpose X509_PURPOSE_ANY is "any purpose" which automatically
1924 accepts a certificate or CA, this was the previous behaviour,
1925 with all the associated security issues.
1927 X509_TRUST_COMPAT is the old trust behaviour: only and
1928 automatically trust self signed roots in certificate store. A
1929 new trust setting X509_TRUST_DEFAULT is used to specify that
1930 a purpose has no associated trust setting and it should instead
1931 use the value in the default purpose.
1934 *) Fix the PKCS#8 DSA private key code so it decodes keys again
1935 and fix a memory leak.
1938 *) In util/mkerr.pl (which implements 'make errors'), preserve
1939 reason strings from the previous version of the .c file, as
1940 the default to have only downcase letters (and digits) in
1941 automatically generated reasons codes is not always appropriate.
1944 *) In ERR_load_ERR_strings(), build an ERR_LIB_SYS error reason table
1945 using strerror. Previously, ERR_reason_error_string() returned
1946 library names as reason strings for SYSerr; but SYSerr is a special
1947 case where small numbers are errno values, not library numbers.
1950 *) Add '-dsaparam' option to 'openssl dhparam' application. This
1951 converts DSA parameters into DH parameters. (When creating parameters,
1952 DSA_generate_parameters is used.)
1955 *) Include 'length' (recommended exponent length) in C code generated
1956 by 'openssl dhparam -C'.
1959 *) The second argument to set_label in perlasm was already being used
1960 so couldn't be used as a "file scope" flag. Moved to third argument
1964 *) In PEM_ASN1_write_bio and some other functions, use RAND_pseudo_bytes
1965 instead of RAND_bytes for encryption IVs and salts.
1968 *) Include RAND_status() into RAND_METHOD instead of implementing
1969 it only for md_rand.c Otherwise replacing the PRNG by calling
1970 RAND_set_rand_method would be impossible.
1973 *) Don't let DSA_generate_key() enter an infinite loop if the random
1974 number generation fails.
1977 *) New 'rand' application for creating pseudo-random output.
1980 *) Added configuration support for Linux/IA64
1981 [Rolf Haberrecker <rolf@suse.de>]
1983 *) Assembler module support for Mingw32.
1986 *) Shared library support for HPUX (in shlib/).
1987 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE> and Anonymous]
1989 *) Shared library support for Solaris gcc.
1990 [Lutz Behnke <behnke@trustcenter.de>]
1992 Changes between 0.9.4 and 0.9.5 [28 Feb 2000]
1994 *) PKCS7_encrypt() was adding text MIME headers twice because they
1995 were added manually and by SMIME_crlf_copy().
1998 *) In bntest.c don't call BN_rand with zero bits argument.
1999 [Steve Henson, pointed out by Andrew W. Gray <agray@iconsinc.com>]
2001 *) BN_mul bugfix: In bn_mul_part_recursion() only the a>a[n] && b>b[n]
2002 case was implemented. This caused BN_div_recp() to fail occasionally.
2005 *) Add an optional second argument to the set_label() in the perl
2006 assembly language builder. If this argument exists and is set
2007 to 1 it signals that the assembler should use a symbol whose
2008 scope is the entire file, not just the current function. This
2009 is needed with MASM which uses the format label:: for this scope.
2010 [Steve Henson, pointed out by Peter Runestig <peter@runestig.com>]
2012 *) Change the ASN1 types so they are typedefs by default. Before
2013 almost all types were #define'd to ASN1_STRING which was causing
2014 STACK_OF() problems: you couldn't declare STACK_OF(ASN1_UTF8STRING)
2018 *) Change names of new functions to the new get1/get0 naming
2019 convention: After 'get1', the caller owns a reference count
2020 and has to call ..._free; 'get0' returns a pointer to some
2021 data structure without incrementing reference counters.
2022 (Some of the existing 'get' functions increment a reference
2023 counter, some don't.)
2024 Similarly, 'set1' and 'add1' functions increase reference
2025 counters or duplicate objects.
2028 *) Allow for the possibility of temp RSA key generation failure:
2029 the code used to assume it always worked and crashed on failure.
2032 *) Fix potential buffer overrun problem in BIO_printf().
2033 [Ulf Möller, using public domain code by Patrick Powell; problem
2034 pointed out by David Sacerdote <das33@cornell.edu>]
2036 *) Support EGD <http://www.lothar.com/tech/crypto/>. New functions
2037 RAND_egd() and RAND_status(). In the command line application,
2038 the EGD socket can be specified like a seed file using RANDFILE
2042 *) Allow the string CERTIFICATE to be tolerated in PKCS#7 structures.
2043 Some CAs (e.g. Verisign) distribute certificates in this form.
2046 *) Remove the SSL_ALLOW_ADH compile option and set the default cipher
2047 list to exclude them. This means that no special compilation option
2048 is needed to use anonymous DH: it just needs to be included in the
2052 *) Change the EVP_MD_CTX_type macro so its meaning consistent with
2053 EVP_MD_type. The old functionality is available in a new macro called
2054 EVP_MD_md(). Change code that uses it and update docs.
2057 *) ..._ctrl functions now have corresponding ..._callback_ctrl functions
2058 where the 'void *' argument is replaced by a function pointer argument.
2059 Previously 'void *' was abused to point to functions, which works on
2060 many platforms, but is not correct. As these functions are usually
2061 called by macros defined in OpenSSL header files, most source code
2062 should work without changes.
2065 *) <openssl/opensslconf.h> (which is created by Configure) now contains
2066 sections with information on -D... compiler switches used for
2067 compiling the library so that applications can see them. To enable
2068 one of these sections, a pre-processor symbol OPENSSL_..._DEFINES
2069 must be defined. E.g.,
2070 #define OPENSSL_ALGORITHM_DEFINES
2071 #include <openssl/opensslconf.h>
2072 defines all pertinent NO_<algo> symbols, such as NO_IDEA, NO_RSA, etc.
2073 [Richard Levitte, Ulf and Bodo Möller]
2075 *) Bugfix: Tolerate fragmentation and interleaving in the SSL 3/TLS
2079 *) Change the 'other' type in certificate aux info to a STACK_OF
2080 X509_ALGOR. Although not an AlgorithmIdentifier as such it has
2081 the required ASN1 format: arbitrary types determined by an OID.
2084 *) Add some PEM_write_X509_REQ_NEW() functions and a command line
2085 argument to 'req'. This is not because the function is newer or
2086 better than others it just uses the work 'NEW' in the certificate
2087 request header lines. Some software needs this.
2090 *) Reorganise password command line arguments: now passwords can be
2091 obtained from various sources. Delete the PEM_cb function and make
2092 it the default behaviour: i.e. if the callback is NULL and the
2093 usrdata argument is not NULL interpret it as a null terminated pass
2094 phrase. If usrdata and the callback are NULL then the pass phrase
2095 is prompted for as usual.
2098 *) Add support for the Compaq Atalla crypto accelerator. If it is installed,
2099 the support is automatically enabled. The resulting binaries will
2100 autodetect the card and use it if present.
2101 [Ben Laurie and Compaq Inc.]
2103 *) Work around for Netscape hang bug. This sends certificate request
2104 and server done in one record. Since this is perfectly legal in the
2105 SSL/TLS protocol it isn't a "bug" option and is on by default. See
2106 the bugs/SSLv3 entry for more info.
2109 *) HP-UX tune-up: new unified configs, HP C compiler bug workaround.
2112 *) Add -rand argument to smime and pkcs12 applications and read/write
2116 *) New 'passwd' tool for crypt(3) and apr1 password hashes.
2119 *) Add command line password options to the remaining applications.
2122 *) Bug fix for BN_div_recp() for numerators with an even number of
2126 *) More tests in bntest.c, and changed test_bn output.
2129 *) ./config recognizes MacOS X now.
2132 *) Bug fix for BN_div() when the first words of num and divsor are
2133 equal (it gave wrong results if (rem=(n1-q*d0)&BN_MASK2) < d0).
2136 *) Add support for various broken PKCS#8 formats, and command line
2137 options to produce them.
2140 *) New functions BN_CTX_start(), BN_CTX_get() and BT_CTX_end() to
2141 get temporary BIGNUMs from a BN_CTX.
2144 *) Correct return values in BN_mod_exp_mont() and BN_mod_exp2_mont()
2148 *) Change the SSLeay_add_all_*() functions to OpenSSL_add_all_*() and
2149 include a #define from the old name to the new. The original intent
2150 was that statically linked binaries could for example just call
2151 SSLeay_add_all_ciphers() to just add ciphers to the table and not
2152 link with digests. This never worked becayse SSLeay_add_all_digests()
2153 and SSLeay_add_all_ciphers() were in the same source file so calling
2154 one would link with the other. They are now in separate source files.
2157 *) Add a new -notext option to 'ca' and a -pubkey option to 'spkac'.
2160 *) Use a less unusual form of the Miller-Rabin primality test (it used
2161 a binary algorithm for exponentiation integrated into the Miller-Rabin
2162 loop, our standard modexp algorithms are faster).
2165 *) Support for the EBCDIC character set completed.
2166 [Martin Kraemer <Martin.Kraemer@Mch.SNI.De>]
2168 *) Source code cleanups: use const where appropriate, eliminate casts,
2169 use void * instead of char * in lhash.
2172 *) Bugfix: ssl3_send_server_key_exchange was not restartable
2173 (the state was not changed to SSL3_ST_SW_KEY_EXCH_B, and because of
2174 this the server could overwrite ephemeral keys that the client
2178 *) Turn DSA_is_prime into a macro that calls BN_is_prime,
2179 using 50 iterations of the Rabin-Miller test.
2181 DSA_generate_parameters now uses BN_is_prime_fasttest (with 50
2182 iterations of the Rabin-Miller test as required by the appendix
2183 to FIPS PUB 186[-1]) instead of DSA_is_prime.
2184 As BN_is_prime_fasttest includes trial division, DSA parameter
2185 generation becomes much faster.
2187 This implies a change for the callback functions in DSA_is_prime
2188 and DSA_generate_parameters: The callback function is called once
2189 for each positive witness in the Rabin-Miller test, not just
2190 occasionally in the inner loop; and the parameters to the
2191 callback function now provide an iteration count for the outer
2192 loop rather than for the current invocation of the inner loop.
2193 DSA_generate_parameters additionally can call the callback
2194 function with an 'iteration count' of -1, meaning that a
2195 candidate has passed the trial division test (when q is generated
2196 from an application-provided seed, trial division is skipped).
2199 *) New function BN_is_prime_fasttest that optionally does trial
2200 division before starting the Rabin-Miller test and has
2201 an additional BN_CTX * argument (whereas BN_is_prime always
2202 has to allocate at least one BN_CTX).
2203 'callback(1, -1, cb_arg)' is called when a number has passed the
2204 trial division stage.
2207 *) Fix for bug in CRL encoding. The validity dates weren't being handled
2211 *) New -pkcs12 option to CA.pl script to write out a PKCS#12 file.
2214 *) New function BN_pseudo_rand().
2217 *) Clean up BN_mod_mul_montgomery(): replace the broken (and unreadable)
2218 bignum version of BN_from_montgomery() with the working code from
2219 SSLeay 0.9.0 (the word based version is faster anyway), and clean up
2223 *) Avoid a race condition in s2_clnt.c (function get_server_hello) that
2224 made it impossible to use the same SSL_SESSION data structure in
2225 SSL2 clients in multiple threads.
2228 *) The return value of RAND_load_file() no longer counts bytes obtained
2229 by stat(). RAND_load_file(..., -1) is new and uses the complete file
2230 to seed the PRNG (previously an explicit byte count was required).
2231 [Ulf Möller, Bodo Möller]
2233 *) Clean up CRYPTO_EX_DATA functions, some of these didn't have prototypes
2234 used (char *) instead of (void *) and had casts all over the place.
2237 *) Make BN_generate_prime() return NULL on error if ret!=NULL.
2240 *) Retain source code compatibility for BN_prime_checks macro:
2241 BN_is_prime(..., BN_prime_checks, ...) now uses
2242 BN_prime_checks_for_size to determine the appropriate number of
2243 Rabin-Miller iterations.
2246 *) Diffie-Hellman uses "safe" primes: DH_check() return code renamed to
2247 DH_CHECK_P_NOT_SAFE_PRIME.
2248 (Check if this is true? OpenPGP calls them "strong".)
2251 *) Merge the functionality of "dh" and "gendh" programs into a new program
2252 "dhparam". The old programs are retained for now but will handle DH keys
2253 (instead of parameters) in future.
2256 *) Make the ciphers, s_server and s_client programs check the return values
2257 when a new cipher list is set.
2260 *) Enhance the SSL/TLS cipher mechanism to correctly handle the TLS 56bit
2261 ciphers. Before when the 56bit ciphers were enabled the sorting was
2264 The syntax for the cipher sorting has been extended to support sorting by
2265 cipher-strength (using the strength_bits hard coded in the tables).
2266 The new command is "@STRENGTH" (see also doc/apps/ciphers.pod).
2268 Fix a bug in the cipher-command parser: when supplying a cipher command
2269 string with an "undefined" symbol (neither command nor alphanumeric
2270 [A-Za-z0-9], ssl_set_cipher_list used to hang in an endless loop. Now
2271 an error is flagged.
2273 Due to the strength-sorting extension, the code of the
2274 ssl_create_cipher_list() function was completely rearranged. I hope that
2275 the readability was also increased :-)
2276 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
2278 *) Minor change to 'x509' utility. The -CAcreateserial option now uses 1
2279 for the first serial number and places 2 in the serial number file. This
2280 avoids problems when the root CA is created with serial number zero and
2281 the first user certificate has the same issuer name and serial number
2285 *) Fixes to X509_ATTRIBUTE utilities, change the 'req' program so it uses
2286 the new code. Add documentation for this stuff.
2289 *) Changes to X509_ATTRIBUTE utilities. These have been renamed from
2290 X509_*() to X509at_*() on the grounds that they don't handle X509
2291 structures and behave in an analagous way to the X509v3 functions:
2292 they shouldn't be called directly but wrapper functions should be used
2295 So we also now have some wrapper functions that call the X509at functions
2296 when passed certificate requests. (TO DO: similar things can be done with
2297 PKCS#7 signed and unsigned attributes, PKCS#12 attributes and a few other
2298 things. Some of these need some d2i or i2d and print functionality
2299 because they handle more complex structures.)
2302 *) Add missing #ifndefs that caused missing symbols when building libssl
2303 as a shared library without RSA. Use #ifndef NO_SSL2 instead of
2304 NO_RSA in ssl/s2*.c.
2305 [Kris Kennaway <kris@hub.freebsd.org>, modified by Ulf Möller]
2307 *) Precautions against using the PRNG uninitialized: RAND_bytes() now
2308 has a return value which indicates the quality of the random data
2309 (1 = ok, 0 = not seeded). Also an error is recorded on the thread's
2310 error queue. New function RAND_pseudo_bytes() generates output that is
2311 guaranteed to be unique but not unpredictable. RAND_add is like
2312 RAND_seed, but takes an extra argument for an entropy estimate
2313 (RAND_seed always assumes full entropy).
2316 *) Do more iterations of Rabin-Miller probable prime test (specifically,
2317 3 for 1024-bit primes, 6 for 512-bit primes, 12 for 256-bit primes
2318 instead of only 2 for all lengths; see BN_prime_checks_for_size definition
2319 in crypto/bn/bn_prime.c for the complete table). This guarantees a
2320 false-positive rate of at most 2^-80 for random input.
2323 *) Rewrite ssl3_read_n (ssl/s3_pkt.c) avoiding a couple of bugs.
2326 *) New function X509_CTX_rget_chain() (renamed to X509_CTX_get1_chain
2327 in the 0.9.5 release), this returns the chain
2328 from an X509_CTX structure with a dup of the stack and all
2329 the X509 reference counts upped: so the stack will exist
2330 after X509_CTX_cleanup() has been called. Modify pkcs12.c
2333 Also make SSL_SESSION_print() print out the verify return
2337 *) Add manpage for the pkcs12 command. Also change the default
2338 behaviour so MAC iteration counts are used unless the new
2339 -nomaciter option is used. This improves file security and
2340 only older versions of MSIE (4.0 for example) need it.
2343 *) Honor the no-xxx Configure options when creating .DEF files.
2346 *) Add PKCS#10 attributes to field table: challengePassword,
2347 unstructuredName and unstructuredAddress. These are taken from
2348 draft PKCS#9 v2.0 but are compatible with v1.2 provided no
2349 international characters are used.
2351 More changes to X509_ATTRIBUTE code: allow the setting of types
2352 based on strings. Remove the 'loc' parameter when adding
2353 attributes because these will be a SET OF encoding which is sorted
2357 *) Initial changes to the 'req' utility to allow request generation
2358 automation. This will allow an application to just generate a template
2359 file containing all the field values and have req construct the
2362 Initial support for X509_ATTRIBUTE handling. Stacks of these are
2363 used all over the place including certificate requests and PKCS#7
2364 structures. They are currently handled manually where necessary with
2365 some primitive wrappers for PKCS#7. The new functions behave in a
2366 manner analogous to the X509 extension functions: they allow
2367 attributes to be looked up by NID and added.
2369 Later something similar to the X509V3 code would be desirable to
2370 automatically handle the encoding, decoding and printing of the
2371 more complex types. The string types like challengePassword can
2372 be handled by the string table functions.
2374 Also modified the multi byte string table handling. Now there is
2375 a 'global mask' which masks out certain types. The table itself
2376 can use the flag STABLE_NO_MASK to ignore the mask setting: this
2377 is useful when for example there is only one permissible type
2378 (as in countryName) and using the mask might result in no valid
2382 *) Clean up 'Finished' handling, and add functions SSL_get_finished and
2383 SSL_get_peer_finished to allow applications to obtain the latest
2384 Finished messages sent to the peer or expected from the peer,
2385 respectively. (SSL_get_peer_finished is usually the Finished message
2386 actually received from the peer, otherwise the protocol will be aborted.)
2388 As the Finished message are message digests of the complete handshake
2389 (with a total of 192 bits for TLS 1.0 and more for SSL 3.0), they can
2390 be used for external authentication procedures when the authentication
2391 provided by SSL/TLS is not desired or is not enough.
2394 *) Enhanced support for Alpha Linux is added. Now ./config checks if
2395 the host supports BWX extension and if Compaq C is present on the
2396 $PATH. Just exploiting of the BWX extension results in 20-30%
2397 performance kick for some algorithms, e.g. DES and RC4 to mention
2398 a couple. Compaq C in turn generates ~20% faster code for MD5 and
2402 *) Add support for MS "fast SGC". This is arguably a violation of the
2403 SSL3/TLS protocol. Netscape SGC does two handshakes: the first with
2404 weak crypto and after checking the certificate is SGC a second one
2405 with strong crypto. MS SGC stops the first handshake after receiving
2406 the server certificate message and sends a second client hello. Since
2407 a server will typically do all the time consuming operations before
2408 expecting any further messages from the client (server key exchange
2409 is the most expensive) there is little difference between the two.
2411 To get OpenSSL to support MS SGC we have to permit a second client
2412 hello message after we have sent server done. In addition we have to
2413 reset the MAC if we do get this second client hello.
2416 *) Add a function 'd2i_AutoPrivateKey()' this will automatically decide
2417 if a DER encoded private key is RSA or DSA traditional format. Changed
2418 d2i_PrivateKey_bio() to use it. This is only needed for the "traditional"
2419 format DER encoded private key. Newer code should use PKCS#8 format which
2420 has the key type encoded in the ASN1 structure. Added DER private key
2421 support to pkcs8 application.
2424 *) SSL 3/TLS 1 servers now don't request certificates when an anonymous
2425 ciphersuites has been selected (as required by the SSL 3/TLS 1
2426 specifications). Exception: When SSL_VERIFY_FAIL_IF_NO_PEER_CERT
2427 is set, we interpret this as a request to violate the specification
2428 (the worst that can happen is a handshake failure, and 'correct'
2429 behaviour would result in a handshake failure anyway).
2432 *) In SSL_CTX_add_session, take into account that there might be multiple
2433 SSL_SESSION structures with the same session ID (e.g. when two threads
2434 concurrently obtain them from an external cache).
2435 The internal cache can handle only one SSL_SESSION with a given ID,
2436 so if there's a conflict, we now throw out the old one to achieve
2440 *) Add OIDs for idea and blowfish in CBC mode. This will allow both
2441 to be used in PKCS#5 v2.0 and S/MIME. Also add checking to
2442 some routines that use cipher OIDs: some ciphers do not have OIDs
2443 defined and so they cannot be used for S/MIME and PKCS#5 v2.0 for
2447 *) Simplify the trust setting structure and code. Now we just have
2448 two sequences of OIDs for trusted and rejected settings. These will
2449 typically have values the same as the extended key usage extension
2450 and any application specific purposes.
2452 The trust checking code now has a default behaviour: it will just
2453 check for an object with the same NID as the passed id. Functions can
2454 be provided to override either the default behaviour or the behaviour
2455 for a given id. SSL client, server and email already have functions
2456 in place for compatibility: they check the NID and also return "trusted"
2457 if the certificate is self signed.
2460 *) Add d2i,i2d bio/fp functions for PrivateKey: these convert the
2461 traditional format into an EVP_PKEY structure.
2464 *) Add a password callback function PEM_cb() which either prompts for
2465 a password if usr_data is NULL or otherwise assumes it is a null
2466 terminated password. Allow passwords to be passed on command line
2467 environment or config files in a few more utilities.
2470 *) Add a bunch of DER and PEM functions to handle PKCS#8 format private
2471 keys. Add some short names for PKCS#8 PBE algorithms and allow them
2472 to be specified on the command line for the pkcs8 and pkcs12 utilities.
2473 Update documentation.
2476 *) Support for ASN1 "NULL" type. This could be handled before by using
2477 ASN1_TYPE but there wasn't any function that would try to read a NULL
2478 and produce an error if it couldn't. For compatibility we also have
2479 ASN1_NULL_new() and ASN1_NULL_free() functions but these are faked and
2480 don't allocate anything because they don't need to.
2483 *) Initial support for MacOS is now provided. Examine INSTALL.MacOS
2485 [Andy Polyakov, Roy Woods <roy@centicsystems.ca>]
2487 *) Rebuild of the memory allocation routines used by OpenSSL code and
2488 possibly others as well. The purpose is to make an interface that
2489 provide hooks so anyone can build a separate set of allocation and
2490 deallocation routines to be used by OpenSSL, for example memory
2491 pool implementations, or something else, which was previously hard
2492 since Malloc(), Realloc() and Free() were defined as macros having
2493 the values malloc, realloc and free, respectively (except for Win32
2494 compilations). The same is provided for memory debugging code.
2495 OpenSSL already comes with functionality to find memory leaks, but
2496 this gives people a chance to debug other memory problems.
2498 With these changes, a new set of functions and macros have appeared:
2500 CRYPTO_set_mem_debug_functions() [F]
2501 CRYPTO_get_mem_debug_functions() [F]
2502 CRYPTO_dbg_set_options() [F]
2503 CRYPTO_dbg_get_options() [F]
2504 CRYPTO_malloc_debug_init() [M]
2506 The memory debug functions are NULL by default, unless the library
2507 is compiled with CRYPTO_MDEBUG or friends is defined. If someone
2508 wants to debug memory anyway, CRYPTO_malloc_debug_init() (which
2509 gives the standard debugging functions that come with OpenSSL) or
2510 CRYPTO_set_mem_debug_functions() (tells OpenSSL to use functions
2511 provided by the library user) must be used. When the standard
2512 debugging functions are used, CRYPTO_dbg_set_options can be used to
2513 request additional information:
2514 CRYPTO_dbg_set_options(V_CYRPTO_MDEBUG_xxx) corresponds to setting
2515 the CRYPTO_MDEBUG_xxx macro when compiling the library.
2517 Also, things like CRYPTO_set_mem_functions will always give the
2518 expected result (the new set of functions is used for allocation
2519 and deallocation) at all times, regardless of platform and compiler
2522 To finish it up, some functions that were never use in any other
2523 way than through macros have a new API and new semantic:
2526 CRYPTO_dbg_realloc()
2529 All macros of value have retained their old syntax.
2530 [Richard Levitte and Bodo Moeller]
2532 *) Some S/MIME fixes. The OID for SMIMECapabilities was wrong, the
2533 ordering of SMIMECapabilities wasn't in "strength order" and there
2534 was a missing NULL in the AlgorithmIdentifier for the SHA1 signature
2538 *) Some ASN1 types with illegal zero length encoding (INTEGER,
2539 ENUMERATED and OBJECT IDENTIFIER) choked the ASN1 routines.
2540 [Frans Heymans <fheymans@isaserver.be>, modified by Steve Henson]
2542 *) Merge in my S/MIME library for OpenSSL. This provides a simple
2543 S/MIME API on top of the PKCS#7 code, a MIME parser (with enough
2544 functionality to handle multipart/signed properly) and a utility
2545 called 'smime' to call all this stuff. This is based on code I
2546 originally wrote for Celo who have kindly allowed it to be
2547 included in OpenSSL.
2550 *) Add variants des_set_key_checked and des_set_key_unchecked of
2551 des_set_key (aka des_key_sched). Global variable des_check_key
2552 decides which of these is called by des_set_key; this way
2553 des_check_key behaves as it always did, but applications and
2554 the library itself, which was buggy for des_check_key == 1,
2555 have a cleaner way to pick the version they need.
2558 *) New function PKCS12_newpass() which changes the password of a
2562 *) Modify X509_TRUST and X509_PURPOSE so it also uses a static and
2563 dynamic mix. In both cases the ids can be used as an index into the
2564 table. Also modified the X509_TRUST_add() and X509_PURPOSE_add()
2565 functions so they accept a list of the field values and the
2566 application doesn't need to directly manipulate the X509_TRUST
2570 *) Modify the ASN1_STRING_TABLE stuff so it also uses bsearch and doesn't
2574 *) Modify the way the V3 extension code looks up extensions. This now
2575 works in a similar way to the object code: we have some "standard"
2576 extensions in a static table which is searched with OBJ_bsearch()
2577 and the application can add dynamic ones if needed. The file
2578 crypto/x509v3/ext_dat.h now has the info: this file needs to be
2579 updated whenever a new extension is added to the core code and kept
2580 in ext_nid order. There is a simple program 'tabtest.c' which checks
2581 this. New extensions are not added too often so this file can readily
2582 be maintained manually.
2584 There are two big advantages in doing things this way. The extensions
2585 can be looked up immediately and no longer need to be "added" using
2586 X509V3_add_standard_extensions(): this function now does nothing.
2587 [Side note: I get *lots* of email saying the extension code doesn't
2588 work because people forget to call this function]
2589 Also no dynamic allocation is done unless new extensions are added:
2590 so if we don't add custom extensions there is no need to call
2591 X509V3_EXT_cleanup().
2594 *) Modify enc utility's salting as follows: make salting the default. Add a
2595 magic header, so unsalted files fail gracefully instead of just decrypting
2596 to garbage. This is because not salting is a big security hole, so people
2597 should be discouraged from doing it.
2600 *) Fixes and enhancements to the 'x509' utility. It allowed a message
2601 digest to be passed on the command line but it only used this
2602 parameter when signing a certificate. Modified so all relevant
2603 operations are affected by the digest parameter including the
2604 -fingerprint and -x509toreq options. Also -x509toreq choked if a
2605 DSA key was used because it didn't fix the digest.
2608 *) Initial certificate chain verify code. Currently tests the untrusted
2609 certificates for consistency with the verify purpose (which is set
2610 when the X509_STORE_CTX structure is set up) and checks the pathlength.
2612 There is a NO_CHAIN_VERIFY compilation option to keep the old behaviour:
2613 this is because it will reject chains with invalid extensions whereas
2614 every previous version of OpenSSL and SSLeay made no checks at all.
2616 Trust code: checks the root CA for the relevant trust settings. Trust
2617 settings have an initial value consistent with the verify purpose: e.g.
2618 if the verify purpose is for SSL client use it expects the CA to be
2619 trusted for SSL client use. However the default value can be changed to
2620 permit custom trust settings: one example of this would be to only trust
2621 certificates from a specific "secure" set of CAs.
2623 Also added X509_STORE_CTX_new() and X509_STORE_CTX_free() functions
2624 which should be used for version portability: especially since the
2625 verify structure is likely to change more often now.
2627 SSL integration. Add purpose and trust to SSL_CTX and SSL and functions
2628 to set them. If not set then assume SSL clients will verify SSL servers
2631 Two new options to the verify program: -untrusted allows a set of
2632 untrusted certificates to be passed in and -purpose which sets the
2633 intended purpose of the certificate. If a purpose is set then the
2634 new chain verify code is used to check extension consistency.
2637 *) Support for the authority information access extension.
2640 *) Modify RSA and DSA PEM read routines to transparently handle
2641 PKCS#8 format private keys. New *_PUBKEY_* functions that handle
2642 public keys in a format compatible with certificate
2643 SubjectPublicKeyInfo structures. Unfortunately there were already
2644 functions called *_PublicKey_* which used various odd formats so
2645 these are retained for compatibility: however the DSA variants were
2646 never in a public release so they have been deleted. Changed dsa/rsa
2647 utilities to handle the new format: note no releases ever handled public
2648 keys so we should be OK.
2650 The primary motivation for this change is to avoid the same fiasco
2651 that dogs private keys: there are several incompatible private key
2652 formats some of which are standard and some OpenSSL specific and
2653 require various evil hacks to allow partial transparent handling and
2654 even then it doesn't work with DER formats. Given the option anything
2655 other than PKCS#8 should be dumped: but the other formats have to
2656 stay in the name of compatibility.
2658 With public keys and the benefit of hindsight one standard format
2659 is used which works with EVP_PKEY, RSA or DSA structures: though
2660 it clearly returns an error if you try to read the wrong kind of key.
2662 Added a -pubkey option to the 'x509' utility to output the public key.
2663 Also rename the EVP_PKEY_get_*() to EVP_PKEY_rget_*()
2664 (renamed to EVP_PKEY_get1_*() in the OpenSSL 0.9.5 release) and add
2665 EVP_PKEY_rset_*() functions (renamed to EVP_PKEY_set1_*())
2666 that do the same as the EVP_PKEY_assign_*() except they up the
2667 reference count of the added key (they don't "swallow" the
2671 *) Fixes to crypto/x509/by_file.c the code to read in certificates and
2672 CRLs would fail if the file contained no certificates or no CRLs:
2673 added a new function to read in both types and return the number
2674 read: this means that if none are read it will be an error. The
2675 DER versions of the certificate and CRL reader would always fail
2676 because it isn't possible to mix certificates and CRLs in DER format
2677 without choking one or the other routine. Changed this to just read
2678 a certificate: this is the best we can do. Also modified the code
2679 in apps/verify.c to take notice of return codes: it was previously
2680 attempting to read in certificates from NULL pointers and ignoring
2681 any errors: this is one reason why the cert and CRL reader seemed
2682 to work. It doesn't check return codes from the default certificate
2683 routines: these may well fail if the certificates aren't installed.
2686 *) Code to support otherName option in GeneralName.
2689 *) First update to verify code. Change the verify utility
2690 so it warns if it is passed a self signed certificate:
2691 for consistency with the normal behaviour. X509_verify
2692 has been modified to it will now verify a self signed
2693 certificate if *exactly* the same certificate appears
2694 in the store: it was previously impossible to trust a
2695 single self signed certificate. This means that:
2696 openssl verify ss.pem
2697 now gives a warning about a self signed certificate but
2698 openssl verify -CAfile ss.pem ss.pem
2702 *) For servers, store verify_result in SSL_SESSION data structure
2703 (and add it to external session representation).
2704 This is needed when client certificate verifications fails,
2705 but an application-provided verification callback (set by
2706 SSL_CTX_set_cert_verify_callback) allows accepting the session
2707 anyway (i.e. leaves x509_store_ctx->error != X509_V_OK
2708 but returns 1): When the session is reused, we have to set
2709 ssl->verify_result to the appropriate error code to avoid
2711 [Bodo Moeller, problem pointed out by Lutz Jaenicke]
2713 *) Fix a bug in the new PKCS#7 code: it didn't consider the
2714 case in PKCS7_dataInit() where the signed PKCS7 structure
2715 didn't contain any existing data because it was being created.
2716 [Po-Cheng Chen <pocheng@nst.com.tw>, slightly modified by Steve Henson]
2718 *) Add a salt to the key derivation routines in enc.c. This
2719 forms the first 8 bytes of the encrypted file. Also add a
2720 -S option to allow a salt to be input on the command line.
2723 *) New function X509_cmp(). Oddly enough there wasn't a function
2724 to compare two certificates. We do this by working out the SHA1
2725 hash and comparing that. X509_cmp() will be needed by the trust
2729 *) SSL_get1_session() is like SSL_get_session(), but increments
2730 the reference count in the SSL_SESSION returned.
2731 [Geoff Thorpe <geoff@eu.c2.net>]
2733 *) Fix for 'req': it was adding a null to request attributes.
2734 Also change the X509_LOOKUP and X509_INFO code to handle
2735 certificate auxiliary information.
2738 *) Add support for 40 and 64 bit RC2 and RC4 algorithms: document
2742 *) Add the possibility to add extra information to the memory leak
2743 detecting output, to form tracebacks, showing from where each
2744 allocation was originated: CRYPTO_push_info("constant string") adds
2745 the string plus current file name and line number to a per-thread
2746 stack, CRYPTO_pop_info() does the obvious, CRYPTO_remove_all_info()
2747 is like calling CYRPTO_pop_info() until the stack is empty.
2748 Also updated memory leak detection code to be multi-thread-safe.
2751 *) Add options -text and -noout to pkcs7 utility and delete the
2752 encryption options which never did anything. Update docs.
2755 *) Add options to some of the utilities to allow the pass phrase
2756 to be included on either the command line (not recommended on
2757 OSes like Unix) or read from the environment. Update the
2758 manpages and fix a few bugs.
2761 *) Add a few manpages for some of the openssl commands.
2764 *) Fix the -revoke option in ca. It was freeing up memory twice,
2765 leaking and not finding already revoked certificates.
2768 *) Extensive changes to support certificate auxiliary information.
2769 This involves the use of X509_CERT_AUX structure and X509_AUX
2770 functions. An X509_AUX function such as PEM_read_X509_AUX()
2771 can still read in a certificate file in the usual way but it
2772 will also read in any additional "auxiliary information". By
2773 doing things this way a fair degree of compatibility can be
2774 retained: existing certificates can have this information added
2775 using the new 'x509' options.
2777 Current auxiliary information includes an "alias" and some trust
2778 settings. The trust settings will ultimately be used in enhanced
2779 certificate chain verification routines: currently a certificate
2780 can only be trusted if it is self signed and then it is trusted
2784 *) Fix assembler for Alpha (tested only on DEC OSF not Linux or *BSD).
2785 The problem was that one of the replacement routines had not been working
2786 since SSLeay releases. For now the offending routine has been replaced
2787 with non-optimised assembler. Even so, this now gives around 95%
2788 performance improvement for 1024 bit RSA signs.
2791 *) Hack to fix PKCS#7 decryption when used with some unorthodox RC2
2792 handling. Most clients have the effective key size in bits equal to
2793 the key length in bits: so a 40 bit RC2 key uses a 40 bit (5 byte) key.
2794 A few however don't do this and instead use the size of the decrypted key
2795 to determine the RC2 key length and the AlgorithmIdentifier to determine
2796 the effective key length. In this case the effective key length can still
2797 be 40 bits but the key length can be 168 bits for example. This is fixed
2798 by manually forcing an RC2 key into the EVP_PKEY structure because the
2799 EVP code can't currently handle unusual RC2 key sizes: it always assumes
2800 the key length and effective key length are equal.
2803 *) Add a bunch of functions that should simplify the creation of
2804 X509_NAME structures. Now you should be able to do:
2805 X509_NAME_add_entry_by_txt(nm, "CN", MBSTRING_ASC, "Steve", -1, -1, 0);
2806 and have it automatically work out the correct field type and fill in
2807 the structures. The more adventurous can try:
2808 X509_NAME_add_entry_by_txt(nm, field, MBSTRING_UTF8, str, -1, -1, 0);
2809 and it will (hopefully) work out the correct multibyte encoding.
2812 *) Change the 'req' utility to use the new field handling and multibyte
2813 copy routines. Before the DN field creation was handled in an ad hoc
2814 way in req, ca, and x509 which was rather broken and didn't support
2815 BMPStrings or UTF8Strings. Since some software doesn't implement
2816 BMPStrings or UTF8Strings yet, they can be enabled using the config file
2817 using the dirstring_type option. See the new comment in the default
2818 openssl.cnf for more info.
2821 *) Make crypto/rand/md_rand.c more robust:
2822 - Assure unique random numbers after fork().
2823 - Make sure that concurrent threads access the global counter and
2824 md serializably so that we never lose entropy in them
2825 or use exactly the same state in multiple threads.
2826 Access to the large state is not always serializable because
2827 the additional locking could be a performance killer, and
2828 md should be large enough anyway.
2831 *) New file apps/app_rand.c with commonly needed functionality
2832 for handling the random seed file.
2834 Use the random seed file in some applications that previously did not:
2836 dsaparam -genkey (which also ignored its '-rand' option),
2839 x509 (when signing).
2840 Except on systems with /dev/urandom, it is crucial to have a random
2841 seed file at least for key creation, DSA signing, and for DH exchanges;
2842 for RSA signatures we could do without one.
2844 gendh and gendsa (unlike genrsa) used to read only the first byte
2845 of each file listed in the '-rand' option. The function as previously
2846 found in genrsa is now in app_rand.c and is used by all programs
2847 that support '-rand'.
2850 *) In RAND_write_file, use mode 0600 for creating files;
2851 don't just chmod when it may be too late.
2854 *) Report an error from X509_STORE_load_locations
2855 when X509_LOOKUP_load_file or X509_LOOKUP_add_dir failed.
2858 *) New function ASN1_mbstring_copy() this copies a string in either
2859 ASCII, Unicode, Universal (4 bytes per character) or UTF8 format
2860 into an ASN1_STRING type. A mask of permissible types is passed
2861 and it chooses the "minimal" type to use or an error if not type
2865 *) Add function equivalents to the various macros in asn1.h. The old
2866 macros are retained with an M_ prefix. Code inside the library can
2867 use the M_ macros. External code (including the openssl utility)
2868 should *NOT* in order to be "shared library friendly".
2871 *) Add various functions that can check a certificate's extensions
2872 to see if it usable for various purposes such as SSL client,
2873 server or S/MIME and CAs of these types. This is currently
2874 VERY EXPERIMENTAL but will ultimately be used for certificate chain
2875 verification. Also added a -purpose flag to x509 utility to
2876 print out all the purposes.
2879 *) Add a CRYPTO_EX_DATA to X509 certificate structure and associated
2883 *) New X509V3_{X509,CRL,REVOKED}_get_d2i() functions. These will search
2884 for, obtain and decode and extension and obtain its critical flag.
2885 This allows all the necessary extension code to be handled in a
2886 single function call.
2889 *) RC4 tune-up featuring 30-40% performance improvement on most RISC
2890 platforms. See crypto/rc4/rc4_enc.c for further details.
2893 *) New -noout option to asn1parse. This causes no output to be produced
2894 its main use is when combined with -strparse and -out to extract data
2895 from a file (which may not be in ASN.1 format).
2898 *) Fix for pkcs12 program. It was hashing an invalid certificate pointer
2899 when producing the local key id.
2900 [Richard Levitte <levitte@stacken.kth.se>]
2902 *) New option -dhparam in s_server. This allows a DH parameter file to be
2903 stated explicitly. If it is not stated then it tries the first server
2904 certificate file. The previous behaviour hard coded the filename
2908 *) Add -pubin and -pubout options to the rsa and dsa commands. These allow
2909 a public key to be input or output. For example:
2910 openssl rsa -in key.pem -pubout -out pubkey.pem
2911 Also added necessary DSA public key functions to handle this.
2914 *) Fix so PKCS7_dataVerify() doesn't crash if no certificates are contained
2915 in the message. This was handled by allowing
2916 X509_find_by_issuer_and_serial() to tolerate a NULL passed to it.
2917 [Steve Henson, reported by Sampo Kellomaki <sampo@mail.neuronio.pt>]
2919 *) Fix for bug in d2i_ASN1_bytes(): other ASN1 functions add an extra null
2920 to the end of the strings whereas this didn't. This would cause problems
2921 if strings read with d2i_ASN1_bytes() were later modified.
2922 [Steve Henson, reported by Arne Ansper <arne@ats.cyber.ee>]
2924 *) Fix for base64 decode bug. When a base64 bio reads only one line of
2925 data and it contains EOF it will end up returning an error. This is
2926 caused by input 46 bytes long. The cause is due to the way base64
2927 BIOs find the start of base64 encoded data. They do this by trying a
2928 trial decode on each line until they find one that works. When they
2929 do a flag is set and it starts again knowing it can pass all the
2930 data directly through the decoder. Unfortunately it doesn't reset
2931 the context it uses. This means that if EOF is reached an attempt
2932 is made to pass two EOFs through the context and this causes the
2933 resulting error. This can also cause other problems as well. As is
2934 usual with these problems it takes *ages* to find and the fix is
2935 trivial: move one line.
2936 [Steve Henson, reported by ian@uns.ns.ac.yu (Ivan Nejgebauer) ]
2938 *) Ugly workaround to get s_client and s_server working under Windows. The
2939 old code wouldn't work because it needed to select() on sockets and the
2940 tty (for keypresses and to see if data could be written). Win32 only
2941 supports select() on sockets so we select() with a 1s timeout on the
2942 sockets and then see if any characters are waiting to be read, if none
2943 are present then we retry, we also assume we can always write data to
2944 the tty. This isn't nice because the code then blocks until we've
2945 received a complete line of data and it is effectively polling the
2946 keyboard at 1s intervals: however it's quite a bit better than not
2947 working at all :-) A dedicated Windows application might handle this
2948 with an event loop for example.
2951 *) Enhance RSA_METHOD structure. Now there are two extra methods, rsa_sign
2952 and rsa_verify. When the RSA_FLAGS_SIGN_VER option is set these functions
2953 will be called when RSA_sign() and RSA_verify() are used. This is useful
2954 if rsa_pub_dec() and rsa_priv_enc() equivalents are not available.
2955 For this to work properly RSA_public_decrypt() and RSA_private_encrypt()
2956 should *not* be used: RSA_sign() and RSA_verify() must be used instead.
2957 This necessitated the support of an extra signature type NID_md5_sha1
2958 for SSL signatures and modifications to the SSL library to use it instead
2959 of calling RSA_public_decrypt() and RSA_private_encrypt().
2962 *) Add new -verify -CAfile and -CApath options to the crl program, these
2963 will lookup a CRL issuers certificate and verify the signature in a
2964 similar way to the verify program. Tidy up the crl program so it
2965 no longer accesses structures directly. Make the ASN1 CRL parsing a bit
2966 less strict. It will now permit CRL extensions even if it is not
2967 a V2 CRL: this will allow it to tolerate some broken CRLs.
2970 *) Initialize all non-automatic variables each time one of the openssl
2971 sub-programs is started (this is necessary as they may be started
2972 multiple times from the "OpenSSL>" prompt).
2973 [Lennart Bang, Bodo Moeller]
2975 *) Preliminary compilation option RSA_NULL which disables RSA crypto without
2976 removing all other RSA functionality (this is what NO_RSA does). This
2977 is so (for example) those in the US can disable those operations covered
2978 by the RSA patent while allowing storage and parsing of RSA keys and RSA
2982 *) Non-copying interface to BIO pairs.
2983 (still largely untested)
2986 *) New function ANS1_tag2str() to convert an ASN1 tag to a descriptive
2987 ASCII string. This was handled independently in various places before.
2990 *) New functions UTF8_getc() and UTF8_putc() that parse and generate
2991 UTF8 strings a character at a time.
2994 *) Use client_version from client hello to select the protocol
2995 (s23_srvr.c) and for RSA client key exchange verification
2996 (s3_srvr.c), as required by the SSL 3.0/TLS 1.0 specifications.
2999 *) Add various utility functions to handle SPKACs, these were previously
3000 handled by poking round in the structure internals. Added new function
3001 NETSCAPE_SPKI_print() to print out SPKAC and a new utility 'spkac' to
3002 print, verify and generate SPKACs. Based on an original idea from
3003 Massimiliano Pala <madwolf@comune.modena.it> but extensively modified.
3006 *) RIPEMD160 is operational on all platforms and is back in 'make test'.
3009 *) Allow the config file extension section to be overwritten on the
3010 command line. Based on an original idea from Massimiliano Pala
3011 <madwolf@comune.modena.it>. The new option is called -extensions
3012 and can be applied to ca, req and x509. Also -reqexts to override
3013 the request extensions in req and -crlexts to override the crl extensions
3017 *) Add new feature to the SPKAC handling in ca. Now you can include
3018 the same field multiple times by preceding it by "XXXX." for example:
3021 this is the same syntax as used in the req config file.
3024 *) Allow certificate extensions to be added to certificate requests. These
3025 are specified in a 'req_extensions' option of the req section of the
3026 config file. They can be printed out with the -text option to req but
3027 are otherwise ignored at present.
3030 *) Fix a horrible bug in enc_read() in crypto/evp/bio_enc.c: if the first
3031 data read consists of only the final block it would not decrypted because
3032 EVP_CipherUpdate() would correctly report zero bytes had been decrypted.
3033 A misplaced 'break' also meant the decrypted final block might not be
3034 copied until the next read.
3037 *) Initial support for DH_METHOD. Again based on RSA_METHOD. Also added
3038 a few extra parameters to the DH structure: these will be useful if
3039 for example we want the value of 'q' or implement X9.42 DH.
3042 *) Initial support for DSA_METHOD. This is based on the RSA_METHOD and
3043 provides hooks that allow the default DSA functions or functions on a
3044 "per key" basis to be replaced. This allows hardware acceleration and
3045 hardware key storage to be handled without major modification to the
3046 library. Also added low level modexp hooks and CRYPTO_EX structure and
3047 associated functions.
3050 *) Add a new flag to memory BIOs, BIO_FLAG_MEM_RDONLY. This marks the BIO
3051 as "read only": it can't be written to and the buffer it points to will
3052 not be freed. Reading from a read only BIO is much more efficient than
3053 a normal memory BIO. This was added because there are several times when
3054 an area of memory needs to be read from a BIO. The previous method was
3055 to create a memory BIO and write the data to it, this results in two
3056 copies of the data and an O(n^2) reading algorithm. There is a new
3057 function BIO_new_mem_buf() which creates a read only memory BIO from
3058 an area of memory. Also modified the PKCS#7 routines to use read only
3062 *) Bugfix: ssl23_get_client_hello did not work properly when called in
3063 state SSL23_ST_SR_CLNT_HELLO_B, i.e. when the first 7 bytes of
3064 a SSLv2-compatible client hello for SSLv3 or TLSv1 could be read,
3065 but a retry condition occured while trying to read the rest.
3068 *) The PKCS7_ENC_CONTENT_new() function was setting the content type as
3069 NID_pkcs7_encrypted by default: this was wrong since this should almost
3070 always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle
3071 the encrypted data type: this is a more sensible place to put it and it
3072 allows the PKCS#12 code to be tidied up that duplicated this
3076 *) Changed obj_dat.pl script so it takes its input and output files on
3077 the command line. This should avoid shell escape redirection problems
3081 *) Initial support for certificate extension requests, these are included
3082 in things like Xenroll certificate requests. Included functions to allow
3083 extensions to be obtained and added.
3086 *) -crlf option to s_client and s_server for sending newlines as
3087 CRLF (as required by many protocols).
3090 Changes between 0.9.3a and 0.9.4 [09 Aug 1999]
3092 *) Install libRSAglue.a when OpenSSL is built with RSAref.
3093 [Ralf S. Engelschall]
3095 *) A few more ``#ifndef NO_FP_API / #endif'' pairs for consistency.
3096 [Andrija Antonijevic <TheAntony2@bigfoot.com>]
3098 *) Fix -startdate and -enddate (which was missing) arguments to 'ca'
3102 *) New function DSA_dup_DH, which duplicates DSA parameters/keys as
3103 DH parameters/keys (q is lost during that conversion, but the resulting
3104 DH parameters contain its length).
3106 For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is
3107 much faster than DH_generate_parameters (which creates parameters
3108 where p = 2*q + 1), and also the smaller q makes DH computations
3109 much more efficient (160-bit exponentiation instead of 1024-bit
3110 exponentiation); so this provides a convenient way to support DHE
3111 ciphersuites in SSL/TLS servers (see ssl/ssltest.c). It is of
3112 utter importance to use
3113 SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
3115 SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
3116 when such DH parameters are used, because otherwise small subgroup
3117 attacks may become possible!
3120 *) Avoid memory leak in i2d_DHparams.
3123 *) Allow the -k option to be used more than once in the enc program:
3124 this allows the same encrypted message to be read by multiple recipients.
3127 *) New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts
3128 an ASN1_OBJECT to a text string. If the "no_name" parameter is set then
3129 it will always use the numerical form of the OID, even if it has a short
3133 *) Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp
3134 method only got called if p,q,dmp1,dmq1,iqmp components were present,
3135 otherwise bn_mod_exp was called. In the case of hardware keys for example
3136 no private key components need be present and it might store extra data
3137 in the RSA structure, which cannot be accessed from bn_mod_exp.
3138 By setting RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for
3139 private key operations.
3142 *) Added support for SPARC Linux.
3145 *) pem_password_cb function type incompatibly changed from
3146 typedef int pem_password_cb(char *buf, int size, int rwflag);
3148 ....(char *buf, int size, int rwflag, void *userdata);
3149 so that applications can pass data to their callbacks:
3150 The PEM[_ASN1]_{read,write}... functions and macros now take an
3151 additional void * argument, which is just handed through whenever
3152 the password callback is called.
3153 [Damien Miller <dmiller@ilogic.com.au>; tiny changes by Bodo Moeller]
3155 New function SSL_CTX_set_default_passwd_cb_userdata.
3157 Compatibility note: As many C implementations push function arguments
3158 onto the stack in reverse order, the new library version is likely to
3159 interoperate with programs that have been compiled with the old
3160 pem_password_cb definition (PEM_whatever takes some data that
3161 happens to be on the stack as its last argument, and the callback
3162 just ignores this garbage); but there is no guarantee whatsoever that
3165 *) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=...
3166 (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused
3167 problems not only on Windows, but also on some Unix platforms.
3168 To avoid problematic command lines, these definitions are now in an
3169 auto-generated file crypto/buildinf.h (created by crypto/Makefile.ssl
3170 for standard "make" builds, by util/mk1mf.pl for "mk1mf" builds).
3173 *) MIPS III/IV assembler module is reimplemented.
3176 *) More DES library cleanups: remove references to srand/rand and
3177 delete an unused file.
3180 *) Add support for the the free Netwide assembler (NASM) under Win32,
3181 since not many people have MASM (ml) and it can be hard to obtain.
3182 This is currently experimental but it seems to work OK and pass all
3183 the tests. Check out INSTALL.W32 for info.
3186 *) Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections
3187 without temporary keys kept an extra copy of the server key,
3188 and connections with temporary keys did not free everything in case
3192 *) New function RSA_check_key and new openssl rsa option -check
3193 for verifying the consistency of RSA keys.
3194 [Ulf Moeller, Bodo Moeller]
3196 *) Various changes to make Win32 compile work:
3197 1. Casts to avoid "loss of data" warnings in p5_crpt2.c
3198 2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned
3199 comparison" warnings.
3200 3. Add sk_<TYPE>_sort to DEF file generator and do make update.
3203 *) Add a debugging option to PKCS#5 v2 key generation function: when
3204 you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and
3205 derived keys are printed to stderr.
3208 *) Copy the flags in ASN1_STRING_dup().
3209 [Roman E. Pavlov <pre@mo.msk.ru>]
3211 *) The x509 application mishandled signing requests containing DSA
3212 keys when the signing key was also DSA and the parameters didn't match.
3214 It was supposed to omit the parameters when they matched the signing key:
3215 the verifying software was then supposed to automatically use the CA's
3216 parameters if they were absent from the end user certificate.
3218 Omitting parameters is no longer recommended. The test was also
3219 the wrong way round! This was probably due to unusual behaviour in
3220 EVP_cmp_parameters() which returns 1 if the parameters match.
3221 This meant that parameters were omitted when they *didn't* match and
3222 the certificate was useless. Certificates signed with 'ca' didn't have
3224 [Steve Henson, reported by Doug Erickson <Doug.Erickson@Part.NET>]
3226 *) Memory leak checking (-DCRYPTO_MDEBUG) had some problems.
3227 The interface is as follows:
3228 Applications can use
3229 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(),
3230 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop();
3231 "off" is now the default.
3232 The library internally uses
3233 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(),
3234 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on()
3235 to disable memory-checking temporarily.
3237 Some inconsistent states that previously were possible (and were
3238 even the default) are now avoided.
3240 -DCRYPTO_MDEBUG_TIME is new and additionally stores the current time
3241 with each memory chunk allocated; this is occasionally more helpful
3242 than just having a counter.
3244 -DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID.
3246 -DCRYPTO_MDEBUG_ALL enables all of the above, plus any future
3250 *) Introduce "mode" for SSL structures (with defaults in SSL_CTX),
3251 which largely parallels "options", but is for changing API behaviour,
3252 whereas "options" are about protocol behaviour.
3253 Initial "mode" flags are:
3255 SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when
3256 a single record has been written.
3257 SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write
3258 retries use the same buffer location.
3259 (But all of the contents must be
3263 *) Bugfix: SSL_set_mode ignored its parameter, only SSL_CTX_set_mode
3266 *) Fix problems with no-hmac etc.
3267 [Ulf Möller, pointed out by Brian Wellington <bwelling@tislabs.com>]
3269 *) New functions RSA_get_default_method(), RSA_set_method() and
3270 RSA_get_method(). These allows replacement of RSA_METHODs without having
3271 to mess around with the internals of an RSA structure.
3274 *) Fix memory leaks in DSA_do_sign and DSA_is_prime.
3275 Also really enable memory leak checks in openssl.c and in some
3277 [Chad C. Mulligan, Bodo Moeller]
3279 *) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess
3280 up the length of negative integers. This has now been simplified to just
3281 store the length when it is first determined and use it later, rather
3282 than trying to keep track of where data is copied and updating it to
3284 [Steve Henson, reported by Brien Wheeler
3285 <bwheeler@authentica-security.com>]
3287 *) Add a new function PKCS7_signatureVerify. This allows the verification
3288 of a PKCS#7 signature but with the signing certificate passed to the
3289 function itself. This contrasts with PKCS7_dataVerify which assumes the
3290 certificate is present in the PKCS#7 structure. This isn't always the
3291 case: certificates can be omitted from a PKCS#7 structure and be
3292 distributed by "out of band" means (such as a certificate database).
3295 *) Complete the PEM_* macros with DECLARE_PEM versions to replace the
3296 function prototypes in pem.h, also change util/mkdef.pl to add the
3297 necessary function names.
3300 *) mk1mf.pl (used by Windows builds) did not properly read the
3301 options set by Configure in the top level Makefile, and Configure
3302 was not even able to write more than one option correctly.
3303 Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended.
3306 *) New functions CONF_load_bio() and CONF_load_fp() to allow a config
3307 file to be loaded from a BIO or FILE pointer. The BIO version will
3308 for example allow memory BIOs to contain config info.
3311 *) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS.
3312 Whoever hopes to achieve shared-library compatibility across versions
3313 must use this, not the compile-time macro.
3314 (Exercise 0.9.4: Which is the minimum library version required by
3316 Note: All this applies only to multi-threaded programs, others don't
3320 *) Add missing case to s3_clnt.c state machine -- one of the new SSL tests
3321 through a BIO pair triggered the default case, i.e.
3322 SSLerr(...,SSL_R_UNKNOWN_STATE).
3325 *) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications
3326 can use the SSL library even if none of the specific BIOs is
3330 *) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value
3331 for the encoded length.
3332 [Jeon KyoungHo <khjeon@sds.samsung.co.kr>]
3334 *) Add initial documentation of the X509V3 functions.
3337 *) Add a new pair of functions PEM_write_PKCS8PrivateKey() and
3338 PEM_write_bio_PKCS8PrivateKey() that are equivalent to
3339 PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more
3340 secure PKCS#8 private key format with a high iteration count.
3343 *) Fix determination of Perl interpreter: A perl or perl5
3344 _directory_ in $PATH was also accepted as the interpreter.
3345 [Ralf S. Engelschall]
3347 *) Fix demos/sign/sign.c: well there wasn't anything strictly speaking
3348 wrong with it but it was very old and did things like calling
3349 PEM_ASN1_read() directly and used MD5 for the hash not to mention some
3353 *) Fix demos/selfsign.c: it used obsolete and deleted functions, changed
3354 to use the new extension code.
3357 *) Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c
3358 with macros. This should make it easier to change their form, add extra
3359 arguments etc. Fix a few PEM prototypes which didn't have cipher as a
3363 *) Add to configuration table a new entry that can specify an alternative
3364 name for unistd.h (for pre-POSIX systems); we need this for NeXTstep,
3365 according to Mark Crispin <MRC@Panda.COM>.
3369 *) DES CBC did not update the IV. Weird.
3372 des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does.
3373 Changing the behaviour of the former might break existing programs --
3374 where IV updating is needed, des_ncbc_encrypt can be used.
3377 *) When bntest is run from "make test" it drives bc to check its
3378 calculations, as well as internally checking them. If an internal check
3379 fails, it needs to cause bc to give a non-zero result or make test carries
3380 on without noticing the failure. Fixed.
3383 *) DES library cleanups.
3386 *) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be
3387 used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit
3388 ciphers. NOTE: although the key derivation function has been verified
3389 against some published test vectors it has not been extensively tested
3390 yet. Added a -v2 "cipher" option to pkcs8 application to allow the use
3394 *) Instead of "mkdir -p", which is not fully portable, use new
3395 Perl script "util/mkdir-p.pl".
3398 *) Rewrite the way password based encryption (PBE) is handled. It used to
3399 assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter
3400 structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms
3401 but doesn't apply to PKCS#5 v2.0 where it can be something else. Now
3402 the 'parameter' field of the AlgorithmIdentifier is passed to the
3403 underlying key generation function so it must do its own ASN1 parsing.
3404 This has also changed the EVP_PBE_CipherInit() function which now has a
3405 'parameter' argument instead of literal salt and iteration count values
3406 and the function EVP_PBE_ALGOR_CipherInit() has been deleted.
3409 *) Support for PKCS#5 v1.5 compatible password based encryption algorithms
3410 and PKCS#8 functionality. New 'pkcs8' application linked to openssl.
3411 Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE
3412 KEY" because this clashed with PKCS#8 unencrypted string. Since this
3413 value was just used as a "magic string" and not used directly its
3414 value doesn't matter.
3417 *) Introduce some semblance of const correctness to BN. Shame C doesn't
3421 *) "linux-sparc64" configuration (ultrapenguin).
3422 [Ray Miller <ray.miller@oucs.ox.ac.uk>]
3423 "linux-sparc" configuration.
3424 [Christian Forster <fo@hawo.stw.uni-erlangen.de>]
3426 *) config now generates no-xxx options for missing ciphers.
3429 *) Support the EBCDIC character set (work in progress).
3430 File ebcdic.c not yet included because it has a different license.
3431 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
3433 *) Support BS2000/OSD-POSIX.
3434 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
3436 *) Make callbacks for key generation use void * instead of char *.
3439 *) Make S/MIME samples compile (not yet tested).
3442 *) Additional typesafe stacks.
3445 *) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x).
3449 Changes between 0.9.3 and 0.9.3a [29 May 1999]
3451 *) New configuration variant "sco5-gcc".
3453 *) Updated some demos.
3454 [Sean O Riordain, Wade Scholine]
3456 *) Add missing BIO_free at exit of pkcs12 application.
3459 *) Fix memory leak in conf.c.
3462 *) Updates for Win32 to assembler version of MD5.
3465 *) Set #! path to perl in apps/der_chop to where we found it
3466 instead of using a fixed path.
3469 *) SHA library changes for irix64-mips4-cc.
3472 *) Improvements for VMS support.
3476 Changes between 0.9.2b and 0.9.3 [24 May 1999]
3478 *) Bignum library bug fix. IRIX 6 passes "make test" now!
3479 This also avoids the problems with SC4.2 and unpatched SC5.
3480 [Andy Polyakov <appro@fy.chalmers.se>]
3482 *) New functions sk_num, sk_value and sk_set to replace the previous macros.
3483 These are required because of the typesafe stack would otherwise break
3484 existing code. If old code used a structure member which used to be STACK
3485 and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with
3486 sk_num or sk_value it would produce an error because the num, data members
3487 are not present in STACK_OF. Now it just produces a warning. sk_set
3488 replaces the old method of assigning a value to sk_value
3489 (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code
3490 that does this will no longer work (and should use sk_set instead) but
3491 this could be regarded as a "questionable" behaviour anyway.
3494 *) Fix most of the other PKCS#7 bugs. The "experimental" code can now
3495 correctly handle encrypted S/MIME data.
3498 *) Change type of various DES function arguments from des_cblock
3499 (which means, in function argument declarations, pointer to char)
3500 to des_cblock * (meaning pointer to array with 8 char elements),
3501 which allows the compiler to do more typechecking; it was like
3502 that back in SSLeay, but with lots of ugly casts.
3504 Introduce new type const_des_cblock.
3507 *) Reorganise the PKCS#7 library and get rid of some of the more obvious
3508 problems: find RecipientInfo structure that matches recipient certificate
3509 and initialise the ASN1 structures properly based on passed cipher.
3512 *) Belatedly make the BN tests actually check the results.
3515 *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion
3516 to and from BNs: it was completely broken. New compilation option
3517 NEG_PUBKEY_BUG to allow for some broken certificates that encode public
3518 key elements as negative integers.
3521 *) Reorganize and speed up MD5.
3522 [Andy Polyakov <appro@fy.chalmers.se>]
3525 [Richard Levitte <richard@levitte.org>]
3527 *) New option -out to asn1parse to allow the parsed structure to be
3528 output to a file. This is most useful when combined with the -strparse
3529 option to examine the output of things like OCTET STRINGS.
3532 *) Make SSL library a little more fool-proof by not requiring any longer
3533 that SSL_set_{accept,connect}_state be called before
3534 SSL_{accept,connect} may be used (SSL_set_..._state is omitted
3535 in many applications because usually everything *appeared* to work as
3536 intended anyway -- now it really works as intended).
3539 *) Move openssl.cnf out of lib/.
3542 *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall
3543 -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
3544 -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+
3545 [Ralf S. Engelschall]
3547 *) Various fixes to the EVP and PKCS#7 code. It may now be able to
3548 handle PKCS#7 enveloped data properly.
3549 [Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve]
3551 *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
3552 copying pointers. The cert_st handling is changed by this in
3553 various ways (and thus what used to be known as ctx->default_cert
3554 is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
3555 any longer when s->cert does not give us what we need).
3556 ssl_cert_instantiate becomes obsolete by this change.
3557 As soon as we've got the new code right (possibly it already is?),
3558 we have solved a couple of bugs of the earlier code where s->cert
3559 was used as if it could not have been shared with other SSL structures.
3561 Note that using the SSL API in certain dirty ways now will result
3562 in different behaviour than observed with earlier library versions:
3563 Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
3564 does not influence s as it used to.
3566 In order to clean up things more thoroughly, inside SSL_SESSION
3567 we don't use CERT any longer, but a new structure SESS_CERT
3568 that holds per-session data (if available); currently, this is
3569 the peer's certificate chain and, for clients, the server's certificate
3570 and temporary key. CERT holds only those values that can have
3571 meaningful defaults in an SSL_CTX.
3574 *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure
3575 from the internal representation. Various PKCS#7 fixes: remove some
3576 evil casts and set the enc_dig_alg field properly based on the signing
3580 *) Allow PKCS#12 password to be set from the command line or the
3581 environment. Let 'ca' get its config file name from the environment
3582 variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req'
3586 *) Allow certificate policies extension to use an IA5STRING for the
3587 organization field. This is contrary to the PKIX definition but
3588 VeriSign uses it and IE5 only recognises this form. Document 'x509'
3592 *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic,
3593 without disallowing inline assembler and the like for non-pedantic builds.
3596 *) Support Borland C++ builder.
3597 [Janez Jere <jj@void.si>, modified by Ulf Möller]
3602 *) SHA-1 cleanups and performance enhancements.
3603 [Andy Polyakov <appro@fy.chalmers.se>]
3605 *) Sparc v8plus assembler for the bignum library.
3606 [Andy Polyakov <appro@fy.chalmers.se>]
3608 *) Accept any -xxx and +xxx compiler options in Configure.
3611 *) Update HPUX configuration.
3614 *) Add missing sk_<type>_unshift() function to safestack.h
3615 [Ralf S. Engelschall]
3617 *) New function SSL_CTX_use_certificate_chain_file that sets the
3618 "extra_cert"s in addition to the certificate. (This makes sense
3619 only for "PEM" format files, as chains as a whole are not
3623 *) Support verify_depth from the SSL API.
3624 x509_vfy.c had what can be considered an off-by-one-error:
3625 Its depth (which was not part of the external interface)
3626 was actually counting the number of certificates in a chain;
3627 now it really counts the depth.
3630 *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used
3631 instead of X509err, which often resulted in confusing error
3632 messages since the error codes are not globally unique
3633 (e.g. an alleged error in ssl3_accept when a certificate
3634 didn't match the private key).
3636 *) New function SSL_CTX_set_session_id_context that allows to set a default
3637 value (so that you don't need SSL_set_session_id_context for each
3638 connection using the SSL_CTX).
3641 *) OAEP decoding bug fix.
3644 *) Support INSTALL_PREFIX for package builders, as proposed by
3648 *) New Configure options "threads" and "no-threads". For systems
3649 where the proper compiler options are known (currently Solaris
3650 and Linux), "threads" is the default.
3653 *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
3656 *) Install various scripts to $(OPENSSLDIR)/misc, not to
3657 $(INSTALLTOP)/bin -- they shouldn't clutter directories
3658 such as /usr/local/bin.
3661 *) "make linux-shared" to build shared libraries.
3662 [Niels Poppe <niels@netbox.org>]
3664 *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
3667 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
3668 extension adding in x509 utility.
3671 *) Remove NOPROTO sections and error code comments.
3674 *) Partial rewrite of the DEF file generator to now parse the ANSI
3678 *) New Configure options --prefix=DIR and --openssldir=DIR.
3681 *) Complete rewrite of the error code script(s). It is all now handled
3682 by one script at the top level which handles error code gathering,
3683 header rewriting and C source file generation. It should be much better
3684 than the old method: it now uses a modified version of Ulf's parser to
3685 read the ANSI prototypes in all header files (thus the old K&R definitions
3686 aren't needed for error creation any more) and do a better job of
3687 translating function codes into names. The old 'ASN1 error code imbedded
3688 in a comment' is no longer necessary and it doesn't use .err files which
3689 have now been deleted. Also the error code call doesn't have to appear all
3690 on one line (which resulted in some large lines...).
3693 *) Change #include filenames from <foo.h> to <openssl/foo.h>.
3696 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
3697 0 (which usually indicates a closed connection), but continue reading.
3700 *) Fix some race conditions.
3703 *) Add support for CRL distribution points extension. Add Certificate
3704 Policies and CRL distribution points documentation.
3707 *) Move the autogenerated header file parts to crypto/opensslconf.h.
3710 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
3711 8 of keying material. Merlin has also confirmed interop with this fix
3712 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
3713 [Merlin Hughes <merlin@baltimore.ie>]
3715 *) Fix lots of warnings.
3716 [Richard Levitte <levitte@stacken.kth.se>]
3718 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
3719 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
3720 [Richard Levitte <levitte@stacken.kth.se>]
3722 *) Fix problems with sizeof(long) == 8.
3723 [Andy Polyakov <appro@fy.chalmers.se>]
3725 *) Change functions to ANSI C.
3728 *) Fix typos in error codes.
3729 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
3731 *) Remove defunct assembler files from Configure.
3734 *) SPARC v8 assembler BIGNUM implementation.
3735 [Andy Polyakov <appro@fy.chalmers.se>]
3737 *) Support for Certificate Policies extension: both print and set.
3738 Various additions to support the r2i method this uses.
3741 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
3742 return a const string when you are expecting an allocated buffer.
3745 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
3746 types DirectoryString and DisplayText.
3749 *) Add code to allow r2i extensions to access the configuration database,
3750 add an LHASH database driver and add several ctx helper functions.
3753 *) Fix an evil bug in bn_expand2() which caused various BN functions to
3754 fail when they extended the size of a BIGNUM.
3757 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
3758 support typesafe stack.
3761 *) Fix typo in SSL_[gs]et_options().
3762 [Nils Frostberg <nils@medcom.se>]
3764 *) Delete various functions and files that belonged to the (now obsolete)
3765 old X509V3 handling code.
3768 *) New Configure option "rsaref".
3771 *) Don't auto-generate pem.h.
3774 *) Introduce type-safe ASN.1 SETs.
3777 *) Convert various additional casted stacks to type-safe STACK_OF() variants.
3778 [Ben Laurie, Ralf S. Engelschall, Steve Henson]
3780 *) Introduce type-safe STACKs. This will almost certainly break lots of code
3781 that links with OpenSSL (well at least cause lots of warnings), but fear
3782 not: the conversion is trivial, and it eliminates loads of evil casts. A
3783 few STACKed things have been converted already. Feel free to convert more.
3784 In the fullness of time, I'll do away with the STACK type altogether.
3787 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
3788 specified in <certfile> by updating the entry in the index.txt file.
3789 This way one no longer has to edit the index.txt file manually for
3790 revoking a certificate. The -revoke option does the gory details now.
3791 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
3793 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
3794 `-text' option at all and this way the `-noout -text' combination was
3795 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
3796 [Ralf S. Engelschall]
3798 *) Make sure a corresponding plain text error message exists for the
3799 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
3800 verify callback function determined that a certificate was revoked.
3801 [Ralf S. Engelschall]
3803 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
3804 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
3805 all available cipers including rc5, which was forgotten until now.
3806 In order to let the testing shell script know which algorithms
3807 are available, a new (up to now undocumented) command
3808 "openssl list-cipher-commands" is used.
3811 *) Bugfix: s_client occasionally would sleep in select() when
3812 it should have checked SSL_pending() first.
3815 *) New functions DSA_do_sign and DSA_do_verify to provide access to
3816 the raw DSA values prior to ASN.1 encoding.
3819 *) Tweaks to Configure
3820 [Niels Poppe <niels@netbox.org>]
3822 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
3826 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
3829 *) New config option to avoid instructions that are illegal on the 80386.
3830 The default code is faster, but requires at least a 486.
3833 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
3834 SSL2_SERVER_VERSION (not used at all) macros, which are now the
3835 same as SSL2_VERSION anyway.
3838 *) New "-showcerts" option for s_client.
3841 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
3842 application. Various cleanups and fixes.
3845 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
3846 modify error routines to work internally. Add error codes and PBE init
3847 to library startup routines.
3850 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
3851 packing functions to asn1 and evp. Changed function names and error
3852 codes along the way.
3855 *) PKCS12 integration: and so it begins... First of several patches to
3856 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
3857 objects to objects.h
3860 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
3861 and display support for Thawte strong extranet extension.
3864 *) Add LinuxPPC support.
3865 [Jeff Dubrule <igor@pobox.org>]
3867 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
3868 bn_div_words in alpha.s.
3869 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
3871 *) Make sure the RSA OAEP test is skipped under -DRSAref because
3872 OAEP isn't supported when OpenSSL is built with RSAref.
3873 [Ulf Moeller <ulf@fitug.de>]
3875 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
3876 so they no longer are missing under -DNOPROTO.
3877 [Soren S. Jorvang <soren@t.dk>]
3880 Changes between 0.9.1c and 0.9.2b [22 Mar 1999]
3882 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
3883 doesn't work when the session is reused. Coming soon!
3886 *) Fix a security hole, that allows sessions to be reused in the wrong
3887 context thus bypassing client cert protection! All software that uses
3888 client certs and session caches in multiple contexts NEEDS PATCHING to
3889 allow session reuse! A fuller solution is in the works.
3890 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
3892 *) Some more source tree cleanups (removed obsolete files
3893 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
3894 permission on "config" script to be executable) and a fix for the INSTALL
3896 [Ulf Moeller <ulf@fitug.de>]
3898 *) Remove some legacy and erroneous uses of malloc, free instead of
3900 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
3902 *) Make rsa_oaep_test return non-zero on error.
3903 [Ulf Moeller <ulf@fitug.de>]
3905 *) Add support for native Solaris shared libraries. Configure
3906 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
3907 if someone would make that last step automatic.
3908 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
3910 *) ctx_size was not built with the right compiler during "make links". Fixed.
3913 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
3914 except NULL ciphers". This means the default cipher list will no longer
3915 enable NULL ciphers. They need to be specifically enabled e.g. with
3916 the string "DEFAULT:eNULL".
3919 *) Fix to RSA private encryption routines: if p < q then it would
3920 occasionally produce an invalid result. This will only happen with
3921 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
3924 *) Be less restrictive and allow also `perl util/perlpath.pl
3925 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
3926 because this way one can also use an interpreter named `perl5' (which is
3927 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
3928 installed as `perl').
3929 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
3931 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
3932 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
3934 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
3935 advapi32.lib to Win32 build and change the pem test comparision
3936 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
3937 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
3938 and crypto/des/ede_cbcm_enc.c.
3941 *) DES quad checksum was broken on big-endian architectures. Fixed.
3944 *) Comment out two functions in bio.h that aren't implemented. Fix up the
3945 Win32 test batch file so it (might) work again. The Win32 test batch file
3946 is horrible: I feel ill....
3949 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
3950 in e_os.h. Audit of header files to check ANSI and non ANSI
3951 sections: 10 functions were absent from non ANSI section and not exported
3952 from Windows DLLs. Fixed up libeay.num for new functions.
3955 *) Make `openssl version' output lines consistent.
3956 [Ralf S. Engelschall]
3958 *) Fix Win32 symbol export lists for BIO functions: Added
3959 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
3960 to ms/libeay{16,32}.def.
3961 [Ralf S. Engelschall]
3963 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
3964 fine under Unix and passes some trivial tests I've now added. But the
3965 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
3966 added to make sure no one expects that this stuff really works in the
3967 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
3968 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
3970 [Ralf S. Engelschall]
3972 *) Fix the generation of two part addresses in perl.
3973 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
3975 *) Add config entry for Linux on MIPS.
3976 [John Tobey <jtobey@channel1.com>]
3978 *) Make links whenever Configure is run, unless we are on Windoze.
3981 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
3982 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
3986 *) Add a useful kludge to allow package maintainers to specify compiler and
3987 other platforms details on the command line without having to patch the
3988 Configure script everytime: One now can use ``perl Configure
3989 <id>:<details>'', i.e. platform ids are allowed to have details appended
3990 to them (seperated by colons). This is treated as there would be a static
3991 pre-configured entry in Configure's %table under key <id> with value
3992 <details> and ``perl Configure <id>'' is called. So, when you want to
3993 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
3994 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
3995 now, which overrides the FreeBSD-elf entry on-the-fly.
3996 [Ralf S. Engelschall]
3998 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
4001 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
4002 on the `perl Configure ...' command line. This way one can compile
4003 OpenSSL libraries with Position Independent Code (PIC) which is needed
4004 for linking it into DSOs.
4005 [Ralf S. Engelschall]
4007 *) Remarkably, export ciphers were totally broken and no-one had noticed!
4011 *) Cleaned up the LICENSE document: The official contact for any license
4012 questions now is the OpenSSL core team under openssl-core@openssl.org.
4013 And add a paragraph about the dual-license situation to make sure people
4014 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
4015 to the OpenSSL toolkit.
4016 [Ralf S. Engelschall]
4018 *) General source tree makefile cleanups: Made `making xxx in yyy...'
4019 display consistent in the source tree and replaced `/bin/rm' by `rm'.
4020 Additonally cleaned up the `make links' target: Remove unnecessary
4021 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
4022 to speed processing and no longer clutter the display with confusing
4023 stuff. Instead only the actually done links are displayed.
4024 [Ralf S. Engelschall]
4026 *) Permit null encryption ciphersuites, used for authentication only. It used
4027 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
4028 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
4032 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
4033 signed attributes when verifying signatures (this would break them),
4034 the detached data encoding was wrong and public keys obtained using
4035 X509_get_pubkey() weren't freed.
4038 *) Add text documentation for the BUFFER functions. Also added a work around
4039 to a Win95 console bug. This was triggered by the password read stuff: the
4040 last character typed gets carried over to the next fread(). If you were
4041 generating a new cert request using 'req' for example then the last
4042 character of the passphrase would be CR which would then enter the first
4046 *) Added the new `Includes OpenSSL Cryptography Software' button as
4047 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
4048 button and can be used by applications based on OpenSSL to show the
4049 relationship to the OpenSSL project.
4050 [Ralf S. Engelschall]
4052 *) Remove confusing variables in function signatures in files
4053 ssl/ssl_lib.c and ssl/ssl.h.
4054 [Lennart Bong <lob@kulthea.stacken.kth.se>]
4056 *) Don't install bss_file.c under PREFIX/include/
4057 [Lennart Bong <lob@kulthea.stacken.kth.se>]
4059 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
4060 functions that return function pointers and has support for NT specific
4061 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
4062 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
4063 unsigned to signed types: this was killing the Win32 compile.
4066 *) Add new certificate file to stack functions,
4067 SSL_add_dir_cert_subjects_to_stack() and
4068 SSL_add_file_cert_subjects_to_stack(). These largely supplant
4069 SSL_load_client_CA_file(), and can be used to add multiple certs easily
4070 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
4071 This means that Apache-SSL and similar packages don't have to mess around
4072 to add as many CAs as they want to the preferred list.
4075 *) Experiment with doxygen documentation. Currently only partially applied to
4077 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
4078 openssl.doxy as the configuration file.
4081 *) Get rid of remaining C++-style comments which strict C compilers hate.
4082 [Ralf S. Engelschall, pointed out by Carlos Amengual]
4084 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
4085 compiled in by default: it has problems with large keys.
4088 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
4089 DH private keys and/or callback functions which directly correspond to
4090 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
4091 is needed for applications which have to configure certificates on a
4092 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
4094 For the RSA certificate situation is makes no difference, but
4095 for the DSA certificate situation this fixes the "no shared cipher"
4096 problem where the OpenSSL cipher selection procedure failed because the
4097 temporary keys were not overtaken from the context and the API provided
4098 no way to reconfigure them.
4099 The new functions now let applications reconfigure the stuff and they
4100 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
4101 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
4102 non-public-API function ssl_cert_instantiate() is used as a helper
4103 function and also to reduce code redundancy inside ssl_rsa.c.
4104 [Ralf S. Engelschall]
4106 *) Move s_server -dcert and -dkey options out of the undocumented feature
4107 area because they are useful for the DSA situation and should be
4108 recognized by the users.
4109 [Ralf S. Engelschall]
4111 *) Fix the cipher decision scheme for export ciphers: the export bits are
4112 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
4113 SSL_EXP_MASK. So, the original variable has to be used instead of the
4114 already masked variable.
4115 [Richard Levitte <levitte@stacken.kth.se>]
4117 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
4118 [Richard Levitte <levitte@stacken.kth.se>]
4120 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
4121 from `int' to `unsigned int' because it's a length and initialized by
4122 EVP_DigestFinal() which expects an `unsigned int *'.
4123 [Richard Levitte <levitte@stacken.kth.se>]
4125 *) Don't hard-code path to Perl interpreter on shebang line of Configure
4126 script. Instead use the usual Shell->Perl transition trick.
4127 [Ralf S. Engelschall]
4129 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
4130 (in addition to RSA certificates) to match the behaviour of `openssl dsa
4131 -noout -modulus' as it's already the case for `openssl rsa -noout
4132 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
4133 currently the public key is printed (a decision which was already done by
4134 `openssl dsa -modulus' in the past) which serves a similar purpose.
4135 Additionally the NO_RSA no longer completely removes the whole -modulus
4136 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
4138 [Ralf S. Engelschall]
4140 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
4141 BIO. See the source (crypto/evp/bio_ok.c) for more info.
4142 [Arne Ansper <arne@ats.cyber.ee>]
4144 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
4145 to be added. Now both 'req' and 'ca' can use new objects defined in the
4149 *) Add cool BIO that does syslog (or event log on NT).
4150 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
4152 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
4153 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
4154 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
4155 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
4158 *) Add preliminary config info for new extension code.
4161 *) Make RSA_NO_PADDING really use no padding.
4162 [Ulf Moeller <ulf@fitug.de>]
4164 *) Generate errors when private/public key check is done.
4167 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
4168 for some CRL extensions and new objects added.
4171 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
4172 key usage extension and fuller support for authority key id.
4175 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
4176 padding method for RSA, which is recommended for new applications in PKCS
4177 #1 v2.0 (RFC 2437, October 1998).
4178 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
4179 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
4180 against Bleichbacher's attack on RSA.
4181 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
4184 *) Updates to the new SSL compression code
4185 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
4187 *) Fix so that the version number in the master secret, when passed
4188 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
4189 (because the server will not accept higher), that the version number
4190 is 0x03,0x01, not 0x03,0x00
4191 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
4193 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
4194 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
4195 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
4198 *) Support for RAW extensions where an arbitrary extension can be
4199 created by including its DER encoding. See apps/openssl.cnf for
4203 *) Make sure latest Perl versions don't interpret some generated C array
4204 code as Perl array code in the crypto/err/err_genc.pl script.
4205 [Lars Weber <3weber@informatik.uni-hamburg.de>]
4207 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
4208 not many people have the assembler. Various Win32 compilation fixes and
4209 update to the INSTALL.W32 file with (hopefully) more accurate Win32
4213 *) Modify configure script 'Configure' to automatically create crypto/date.h
4214 file under Win32 and also build pem.h from pem.org. New script
4215 util/mkfiles.pl to create the MINFO file on environments that can't do a
4216 'make files': perl util/mkfiles.pl >MINFO should work.
4219 *) Major rework of DES function declarations, in the pursuit of correctness
4220 and purity. As a result, many evil casts evaporated, and some weirdness,
4221 too. You may find this causes warnings in your code. Zapping your evil
4222 casts will probably fix them. Mostly.
4225 *) Fix for a typo in asn1.h. Bug fix to object creation script
4226 obj_dat.pl. It considered a zero in an object definition to mean
4227 "end of object": none of the objects in objects.h have any zeros
4228 so it wasn't spotted.
4229 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
4231 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
4232 Masking (CBCM). In the absence of test vectors, the best I have been able
4233 to do is check that the decrypt undoes the encrypt, so far. Send me test
4234 vectors if you have them.
4237 *) Correct calculation of key length for export ciphers (too much space was
4238 allocated for null ciphers). This has not been tested!
4241 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
4242 message is now correct (it understands "crypto" and "ssl" on its
4243 command line). There is also now an "update" option. This will update
4244 the util/ssleay.num and util/libeay.num files with any new functions.
4246 perl util/mkdef.pl crypto ssl update
4247 it will update them.
4250 *) Overhauled the Perl interface (perl/*):
4251 - ported BN stuff to OpenSSL's different BN library
4252 - made the perl/ source tree CVS-aware
4253 - renamed the package from SSLeay to OpenSSL (the files still contain
4254 their history because I've copied them in the repository)
4255 - removed obsolete files (the test scripts will be replaced
4256 by better Test::Harness variants in the future)
4257 [Ralf S. Engelschall]
4259 *) First cut for a very conservative source tree cleanup:
4260 1. merge various obsolete readme texts into doc/ssleay.txt
4261 where we collect the old documents and readme texts.
4262 2. remove the first part of files where I'm already sure that we no
4263 longer need them because of three reasons: either they are just temporary
4264 files which were left by Eric or they are preserved original files where
4265 I've verified that the diff is also available in the CVS via "cvs diff
4266 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
4267 the crypto/md/ stuff).
4268 [Ralf S. Engelschall]
4270 *) More extension code. Incomplete support for subject and issuer alt
4271 name, issuer and authority key id. Change the i2v function parameters
4272 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
4273 what that's for :-) Fix to ASN1 macro which messed up
4274 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
4277 *) Preliminary support for ENUMERATED type. This is largely copied from the
4281 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
4282 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
4284 *) Make sure `make rehash' target really finds the `openssl' program.
4285 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
4287 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
4288 like to hear about it if this slows down other processors.
4291 *) Add CygWin32 platform information to Configure script.
4292 [Alan Batie <batie@aahz.jf.intel.com>]
4294 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
4295 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
4297 *) New program nseq to manipulate netscape certificate sequences
4300 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
4304 *) Fixes to BN code. Previously the default was to define BN_RECURSION
4305 but the BN code had some problems that would cause failures when
4306 doing certificate verification and some other functions.
4307 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
4309 *) Add ASN1 and PEM code to support netscape certificate sequences.
4312 *) Add ASN1 and PEM code to support netscape certificate sequences.
4315 *) Add several PKIX and private extended key usage OIDs.
4318 *) Modify the 'ca' program to handle the new extension code. Modify
4319 openssl.cnf for new extension format, add comments.
4322 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
4323 and add a sample to openssl.cnf so req -x509 now adds appropriate
4327 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
4328 error code, add initial support to X509_print() and x509 application.
4331 *) Takes a deep breath and start addding X509 V3 extension support code. Add
4332 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
4333 stuff is currently isolated and isn't even compiled yet.
4336 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
4337 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
4338 Removed the versions check from X509 routines when loading extensions:
4339 this allows certain broken certificates that don't set the version
4340 properly to be processed.
4343 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
4344 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
4345 can still be regenerated with "make depend".
4348 *) Spelling mistake in C version of CAST-128.
4349 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
4351 *) Changes to the error generation code. The perl script err-code.pl
4352 now reads in the old error codes and retains the old numbers, only
4353 adding new ones if necessary. It also only changes the .err files if new
4354 codes are added. The makefiles have been modified to only insert errors
4355 when needed (to avoid needlessly modifying header files). This is done
4356 by only inserting errors if the .err file is newer than the auto generated
4357 C file. To rebuild all the error codes from scratch (the old behaviour)
4358 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
4359 or delete all the .err files.
4362 *) CAST-128 was incorrectly implemented for short keys. The C version has
4363 been fixed, but is untested. The assembler versions are also fixed, but
4364 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
4365 to regenerate it if needed.
4366 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
4367 Hagino <itojun@kame.net>]
4369 *) File was opened incorrectly in randfile.c.
4370 [Ulf Möller <ulf@fitug.de>]
4372 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
4373 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
4374 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
4375 al: it's just almost always a UTCTime. Note this patch adds new error
4376 codes so do a "make errors" if there are problems.
4379 *) Correct Linux 1 recognition in config.
4380 [Ulf Möller <ulf@fitug.de>]
4382 *) Remove pointless MD5 hash when using DSA keys in ca.
4383 [Anonymous <nobody@replay.com>]
4385 *) Generate an error if given an empty string as a cert directory. Also
4386 generate an error if handed NULL (previously returned 0 to indicate an
4387 error, but didn't set one).
4388 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
4390 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
4393 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
4394 parameters. This was causing a warning which killed off the Win32 compile.
4397 *) Remove C++ style comments from crypto/bn/bn_local.h.
4398 [Neil Costigan <neil.costigan@celocom.com>]
4400 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
4401 based on a text string, looking up short and long names and finally
4402 "dot" format. The "dot" format stuff didn't work. Added new function
4403 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
4404 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
4405 OID is not part of the table.
4408 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
4409 X509_LOOKUP_by_alias().
4412 *) Sort openssl functions by name.
4415 *) Get the gendsa program working (hopefully) and add it to app list. Remove
4416 encryption from sample DSA keys (in case anyone is interested the password
4420 *) Make _all_ *_free functions accept a NULL pointer.
4421 [Frans Heymans <fheymans@isaserver.be>]
4423 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
4425 [Anonymous <nobody@replay.com>]
4427 *) s_server should send the CAfile as acceptable CAs, not its own cert.
4428 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
4430 *) Don't blow it for numeric -newkey arguments to apps/req.
4431 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
4433 *) Temp key "for export" tests were wrong in s3_srvr.c.
4434 [Anonymous <nobody@replay.com>]
4436 *) Add prototype for temp key callback functions
4437 SSL_CTX_set_tmp_{rsa,dh}_callback().
4440 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
4441 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
4444 *) X509_name_add_entry() freed the wrong thing after an error.
4445 [Arne Ansper <arne@ats.cyber.ee>]
4447 *) rsa_eay.c would attempt to free a NULL context.
4448 [Arne Ansper <arne@ats.cyber.ee>]
4450 *) BIO_s_socket() had a broken should_retry() on Windoze.
4451 [Arne Ansper <arne@ats.cyber.ee>]
4453 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
4454 [Arne Ansper <arne@ats.cyber.ee>]
4456 *) Make sure the already existing X509_STORE->depth variable is initialized
4457 in X509_STORE_new(), but document the fact that this variable is still
4458 unused in the certificate verification process.
4459 [Ralf S. Engelschall]
4461 *) Fix the various library and apps files to free up pkeys obtained from
4462 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
4465 *) Fix reference counting in X509_PUBKEY_get(). This makes
4466 demos/maurice/example2.c work, amongst others, probably.
4467 [Steve Henson and Ben Laurie]
4469 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
4470 `openssl' and second, the shortcut symlinks for the `openssl <command>'
4471 are no longer created. This way we have a single and consistent command
4472 line interface `openssl <command>', similar to `cvs <command>'.
4473 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
4475 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
4476 BIT STRING wrapper always have zero unused bits.
4479 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
4482 *) Make the top-level INSTALL documentation easier to understand.
4485 *) Makefiles updated to exit if an error occurs in a sub-directory
4486 make (including if user presses ^C) [Paul Sutton]
4488 *) Make Montgomery context stuff explicit in RSA data structure.
4491 *) Fix build order of pem and err to allow for generated pem.h.
4494 *) Fix renumbering bug in X509_NAME_delete_entry().
4497 *) Enhanced the err-ins.pl script so it makes the error library number
4498 global and can add a library name. This is needed for external ASN1 and
4499 other error libraries.
4502 *) Fixed sk_insert which never worked properly.
4505 *) Fix ASN1 macros so they can handle indefinite length construted
4506 EXPLICIT tags. Some non standard certificates use these: they can now
4510 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
4511 into a single doc/ssleay.txt bundle. This way the information is still
4512 preserved but no longer messes up this directory. Now it's new room for
4513 the new set of documenation files.
4514 [Ralf S. Engelschall]
4516 *) SETs were incorrectly DER encoded. This was a major pain, because they
4517 shared code with SEQUENCEs, which aren't coded the same. This means that
4518 almost everything to do with SETs or SEQUENCEs has either changed name or
4519 number of arguments.
4520 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
4522 *) Fix test data to work with the above.
4525 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
4526 was already fixed by Eric for 0.9.1 it seems.
4527 [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
4529 *) Autodetect FreeBSD3.
4532 *) Fix various bugs in Configure. This affects the following platforms:
4536 unixware-2.0-pentium
4540 *) Eliminate generated files from CVS. Reorder tests to regenerate files
4541 before they are needed.
4544 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
4548 Changes between 0.9.1b and 0.9.1c [23-Dec-1998]
4550 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
4551 changed SSLeay to OpenSSL in version strings.
4552 [Ralf S. Engelschall]
4554 *) Some fixups to the top-level documents.
4557 *) Fixed the nasty bug where rsaref.h was not found under compile-time
4558 because the symlink to include/ was missing.
4559 [Ralf S. Engelschall]
4561 *) Incorporated the popular no-RSA/DSA-only patches
4562 which allow to compile a RSA-free SSLeay.
4563 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
4565 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
4566 when "ssleay" is still not found.
4567 [Ralf S. Engelschall]
4569 *) Added more platforms to Configure: Cray T3E, HPUX 11,
4570 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
4572 *) Updated the README file.
4573 [Ralf S. Engelschall]
4575 *) Added various .cvsignore files in the CVS repository subdirs
4576 to make a "cvs update" really silent.
4577 [Ralf S. Engelschall]
4579 *) Recompiled the error-definition header files and added
4580 missing symbols to the Win32 linker tables.
4581 [Ralf S. Engelschall]
4583 *) Cleaned up the top-level documents;
4584 o new files: CHANGES and LICENSE
4585 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
4586 o merged COPYRIGHT into LICENSE
4587 o removed obsolete TODO file
4588 o renamed MICROSOFT to INSTALL.W32
4589 [Ralf S. Engelschall]
4591 *) Removed dummy files from the 0.9.1b source tree:
4592 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
4593 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f

4596 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
4597 [Ralf S. Engelschall]
4599 *) Added various platform portability fixes.
4602 *) The Genesis of the OpenSSL rpject:
4603 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
4604 Young and Tim J. Hudson created while they were working for C2Net until
4606 [The OpenSSL Project]
4609 Changes between 0.9.0b and 0.9.1b [not released]
4611 *) Updated a few CA certificates under certs/
4614 *) Changed some BIGNUM api stuff.
4617 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
4618 DGUX x86, Linux Alpha, etc.
4621 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
4622 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
4626 *) Add -strparse option to asn1pars program which parses nested
4628 [Dr Stephen Henson <shenson@bigfoot.com>]
4630 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
4633 *) DSA fix for "ca" program.
4636 *) Added "-genkey" option to "dsaparam" program.
4639 *) Added RIPE MD160 (rmd160) message digest.
4642 *) Added -a (all) option to "ssleay version" command.
4645 *) Added PLATFORM define which is the id given to Configure.
4648 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
4651 *) Extended the ASN.1 parser routines.
4654 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
4657 *) Added a BN_CTX to the BN library.
4660 *) Fixed the weak key values in DES library
4663 *) Changed API in EVP library for cipher aliases.
4666 *) Added support for RC2/64bit cipher.
4669 *) Converted the lhash library to the crypto/mem.c functions.
4672 *) Added more recognized ASN.1 object ids.
4675 *) Added more RSA padding checks for SSL/TLS.
4678 *) Added BIO proxy/filter functionality.
4681 *) Added extra_certs to SSL_CTX which can be used
4682 send extra CA certificates to the client in the CA cert chain sending
4683 process. It can be configured with SSL_CTX_add_extra_chain_cert().
4686 *) Now Fortezza is denied in the authentication phase because
4687 this is key exchange mechanism is not supported by SSLeay at all.
4690 *) Additional PKCS1 checks.
4693 *) Support the string "TLSv1" for all TLS v1 ciphers.
4696 *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
4697 ex_data index of the SSL context in the X509_STORE_CTX ex_data.
4700 *) Fixed a few memory leaks.
4703 *) Fixed various code and comment typos.
4706 *) A minor bug in ssl/s3_clnt.c where there would always be 4 0
4707 bytes sent in the client random.
