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 *) In versions up to 0.9.6, RAND_file_name() resorted to file ".rnd"
15 in the current directory if neither $RANDFILE nor $HOME was set.
16 RAND_file_name() in 0.9.6a returned NULL in this case. This has
17 caused some confusion to Windows users who haven't defined $HOME.
18 Thus RAND_file_name() is changed again: e_os.h can define a
19 DEFAULT_HOME, which will be used if $HOME is not set.
20 For Windows, we use "C:"; on other platforms, we still require
21 environment variables.
23 +) Add "ex_data" support to ENGINE so implementations can add state at a
24 per-structure level rather than having to store it globally.
27 +) Make it possible for ENGINE structures to be copied when retrieved by
28 ENGINE_by_id() if the ENGINE specifies a new flag: ENGINE_FLAGS_BY_ID_COPY.
29 This causes the "original" ENGINE structure to act like a template,
30 analogous to the RSA vs. RSA_METHOD type of separation. Because of this
31 operational state can be localised to each ENGINE structure, despite the
32 fact they all share the same "methods". New ENGINE structures returned in
33 this case have no functional references and the return value is the single
34 structural reference. This matches the single structural reference returned
35 by ENGINE_by_id() normally, when it is incremented on the pre-existing
39 +) Fix various bugs related to DSA S/MIME verification. Handle missing
40 parameters in DSA public key structures and return an error in the
41 DSA routines if parameters are absent.
44 +) Fix ASN1 decoder when decoding type ANY and V_ASN1_OTHER: since this
45 needs to match any other type at all we need to manually clear the
49 +) Changes to the "openssl engine" utility to include;
50 - verbosity levels ('-v', '-vv', and '-vvv') that provide information
51 about an ENGINE's available control commands.
52 - executing control commands from command line arguments using the
53 '-pre' and '-post' switches. '-post' is only used if '-t' is
54 specified and the ENGINE is successfully initialised. The syntax for
55 the individual commands are colon-separated, for example;
56 openssl engine chil -pre FORK_CHECK:0 -pre SO_PATH:/lib/test.so
59 +) New dynamic control command support for ENGINEs. ENGINEs can now
60 declare their own commands (numbers), names (strings), descriptions,
61 and input types for run-time discovery by calling applications. A
62 subset of these commands are implicitly classed as "executable"
63 depending on their input type, and only these can be invoked through
64 the new string-based API function ENGINE_ctrl_cmd_string(). (Eg. this
65 can be based on user input, config files, etc). The distinction is
66 that "executable" commands cannot return anything other than a boolean
67 result and can only support numeric or string input, whereas some
68 discoverable commands may only be for direct use through
69 ENGINE_ctrl(), eg. supporting the exchange of binary data, function
70 pointers, or other custom uses. The "executable" commands are to
71 support parameterisations of ENGINE behaviour that can be
72 unambiguously defined by ENGINEs and used consistently across any
73 OpenSSL-based application. Commands have been added to all the
74 existing hardware-supporting ENGINEs, noticeably "SO_PATH" to allow
75 control over shared-library paths without source code alterations.
78 +) Changed all ENGINE implementations to dynamically allocate their
79 ENGINEs rather than declaring them statically. Apart from this being
80 necessary with the removal of the ENGINE_FLAGS_MALLOCED distinction,
81 this also allows the implementations to compile without using the
82 internal engine_int.h header.
85 +) Minor adjustment to "rand" code. RAND_get_rand_method() now returns a
86 'const' value. Any code that should be able to modify a RAND_METHOD
87 should already have non-const pointers to it (ie. they should only
88 modify their own ones).
91 +) Made a variety of little tweaks to the ENGINE code.
92 - "atalla" and "ubsec" string definitions were moved from header files
93 to C code. "nuron" string definitions were placed in variables
94 rather than hard-coded - allowing parameterisation of these values
95 later on via ctrl() commands.
96 - Removed unused "#if 0"'d code.
97 - Fixed engine list iteration code so it uses ENGINE_free() to release
98 structural references.
99 - Constified the RAND_METHOD element of ENGINE structures.
100 - Constified various get/set functions as appropriate and added
101 missing functions (including a catch-all ENGINE_cpy that duplicates
102 all ENGINE values onto a new ENGINE except reference counts/state).
103 - Removed NULL parameter checks in get/set functions. Setting a method
104 or function to NULL is a way of cancelling out a previously set
105 value. Passing a NULL ENGINE parameter is just plain stupid anyway
106 and doesn't justify the extra error symbols and code.
107 - Deprecate the ENGINE_FLAGS_MALLOCED define and move the area for
108 flags from engine_int.h to engine.h.
109 - Changed prototypes for ENGINE handler functions (init(), finish(),
110 ctrl(), key-load functions, etc) to take an (ENGINE*) parameter.
113 *) Move 'if (!initialized) RAND_poll()' into regions protected by
114 CRYPTO_LOCK_RAND. This is not strictly necessary, but avoids
115 having multiple threads call RAND_poll() concurrently.
118 *) In crypto/rand/md_rand.c, replace 'add_do_not_lock' flag by a
119 combination of a flag and a thread ID variable.
120 Otherwise while one thread is in ssleay_rand_bytes (which sets the
121 flag), *other* threads can enter ssleay_add_bytes without obeying
122 the CRYPTO_LOCK_RAND lock (and may even illegaly release the lock
123 that they do not hold after the first thread unsets add_do_not_lock).
126 +) Implement binary inversion algorithm for BN_mod_inverse in addition
127 to the algorithm using long divison. The binary algorithm can be
128 used only if the modulus is odd. On 32-bit systems, it is faster
129 only for relatively small moduli (roughly 20-30% for 128-bit moduli,
130 roughly 5-15% for 256-bit moduli), so we use it only for moduli
131 up to 450 bits. In 64-bit environments, the binary algorithm
132 appears to be advantageous for much longer moduli; here we use it
133 for moduli up to 2048 bits.
136 *) Change bctest again: '-x' expressions are not available in all
140 -) OpenSSL 0.9.6a released [5 Apr 2001]
142 *) Fix a couple of memory leaks in PKCS7_dataDecode()
143 [Steve Henson, reported by Heyun Zheng <hzheng@atdsprint.com>]
145 *) Change Configure and Makefiles to provide EXE_EXT, which will contain
146 the default extension for executables, if any. Also, make the perl
147 scripts that use symlink() to test if it really exists and use "cp"
148 if it doesn't. All this made OpenSSL compilable and installable in
152 +) Rewrite CHOICE field setting in ASN1_item_ex_d2i(). The old code
153 could not support the combine flag in choice fields.
156 -) Fix for asn1_GetSequence() for indefinite length constructed data.
157 If SEQUENCE is length is indefinite just set c->slen to the total
158 amount of data available.
159 [Steve Henson, reported by shige@FreeBSD.org]
160 [This change does not apply to 0.9.7.]
162 *) Change bctest to avoid here-documents inside command substitution
163 (workaround for FreeBSD /bin/sh bug).
164 For compatibility with Ultrix, avoid shell functions (introduced
165 in the bctest version that searches along $PATH).
168 *) Rename 'des_encrypt' to 'des_encrypt1'. This avoids the clashes
169 with des_encrypt() defined on some operating systems, like Solaris
173 *) Check the result of RSA-CRT (see D. Boneh, R. DeMillo, R. Lipton:
174 On the Importance of Eliminating Errors in Cryptographic
175 Computations, J. Cryptology 14 (2001) 2, 101-119,
176 http://theory.stanford.edu/~dabo/papers/faults.ps.gz).
179 *) MIPS assembler BIGNUM division bug fix.
182 *) Disabled incorrect Alpha assembler code.
185 -) Fix PKCS#7 decode routines so they correctly update the length
186 after reading an EOC for the EXPLICIT tag.
188 [This change does not apply to 0.9.7.]
190 *) Fix bug in PKCS#12 key generation routines. This was triggered
191 if a 3DES key was generated with a 0 initial byte. Include
192 PKCS12_BROKEN_KEYGEN compilation option to retain the old
193 (but broken) behaviour.
196 *) Enhance bctest to search for a working bc along $PATH and print
198 [Tim Rice <tim@multitalents.net> via Richard Levitte]
200 +) Add a 'copy_extensions' option to the 'ca' utility. This copies
201 extensions from a certificate request to the certificate.
204 +) Allow multiple 'certopt' and 'nameopt' options to be separated
205 by commas. Add 'namopt' and 'certopt' options to the 'ca' config
206 file: this allows the display of the certificate about to be
207 signed to be customised, to allow certain fields to be included
208 or excluded and extension details. The old system didn't display
209 multicharacter strings properly, omitted fields not in the policy
210 and couldn't display additional details such as extensions.
213 *) Fix memory leaks in err.c: free err_data string if necessary;
214 don't write to the wrong index in ERR_set_error_data.
217 +) Function EC_POINTs_mul for simultaneous scalar multiplication
218 of an arbitrary number of elliptic curve points, optionally
219 including the generator defined for the EC_GROUP.
220 EC_POINT_mul is a simple wrapper function for the typical case
221 that the point list has just one item (besides the optional
225 +) First EC_METHODs for curves over GF(p):
227 EC_GFp_simple_method() uses the basic BN_mod_mul and BN_mod_sqr
228 operations and provides various method functions that can also
229 operate with faster implementations of modular arithmetic.
231 EC_GFp_mont_method() reuses most functions that are part of
232 EC_GFp_simple_method, but uses Montgomery arithmetic.
234 [Bodo Moeller; point addition and point doubling
235 implementation directly derived from source code provided by
236 Lenka Fibikova <fibikova@exp-math.uni-essen.de>]
238 +) Framework for elliptic curves (crypto/ec/ec.h, crypto/ec/ec_lcl.h,
241 Curves are EC_GROUP objects (with an optional group generator)
242 based on EC_METHODs that are built into the library.
244 Points are EC_POINT objects based on EC_GROUP objects.
246 Most of the framework would be able to handle curves over arbitrary
247 finite fields, but as there are no obvious types for fields other
248 than GF(p), some functions are limited to that for now.
251 +) Add the -HTTP option to s_server. It is similar to -WWW, but requires
252 that the file contains a complete HTTP response.
255 +) Add the ec directory to mkdef.pl and mkfiles.pl. In mkdef.pl
256 change the def and num file printf format specifier from "%-40sXXX"
257 to "%-39s XXX". The latter will always guarantee a space after the
258 field while the former will cause them to run together if the field
259 is 40 of more characters long.
262 +) Constify the cipher and digest 'method' functions and structures
263 and modify related functions to take constant EVP_MD and EVP_CIPHER
267 *) Implement ssl23_peek (analogous to ssl23_read), which previously
271 *) Replace rdtsc with _emit statements for VC++ version 5.
272 [Jeremy Cooper <jeremy@baymoo.org>]
274 +) Hide BN_CTX structure details in bn_lcl.h instead of publishing them
275 in <openssl/bn.h>. Also further increase BN_CTX_NUM to 32.
278 +) Modify EVP_Digest*() routines so they now return values. Although the
279 internal software routines can never fail additional hardware versions
283 +) Clean up crypto/err/err.h and change some error codes to avoid conflicts:
285 Previously ERR_R_FATAL was too small and coincided with ERR_LIB_PKCS7
286 (= ERR_R_PKCS7_LIB); it is now 64 instead of 32.
289 ERR_R_NESTED_ASN1_ERROR
291 ERR_R_MISSING_ASN1_EOS
292 were 4 .. 9, conflicting with
293 ERR_LIB_RSA (= ERR_R_RSA_LIB)
295 ERR_LIB_PEM (= ERR_R_PEM_LIB).
296 They are now 58 .. 63 (i.e., just below ERR_R_FATAL).
298 Add new error code 'ERR_R_INTERNAL_ERROR'.
301 +) Don't overuse locks in crypto/err/err.c: For data retrieval, CRYPTO_r_lock
305 +) New option '-subj arg' for 'openssl req' and 'openssl ca'. This
306 sets the subject name for a new request or supersedes the
307 subject name in a given request. Formats that can be parsed are
308 'CN=Some Name, OU=myOU, C=IT'
310 'CN=Some Name/OU=myOU/C=IT'.
312 Add options '-batch' and '-verbose' to 'openssl req'.
313 [Massimiliano Pala <madwolf@hackmasters.net>]
315 *) Make it possible to reuse SSLv2 sessions.
318 +) Introduce the possibility to access global variables through
319 functions on platform were that's the best way to handle exporting
320 global variables in shared libraries. To enable this functionality,
321 one must configure with "EXPORT_VAR_AS_FN" or defined the C macro
322 "OPENSSL_EXPORT_VAR_AS_FUNCTION" in crypto/opensslconf.h (the latter
323 is normally done by Configure or something similar).
325 To implement a global variable, use the macro OPENSSL_IMPLEMENT_GLOBAL
326 in the source file (foo.c) like this:
328 OPENSSL_IMPLEMENT_GLOBAL(int,foo)=1;
329 OPENSSL_IMPLEMENT_GLOBAL(double,bar);
331 To declare a global variable, use the macros OPENSSL_DECLARE_GLOBAL
332 and OPENSSL_GLOBAL_REF in the header file (foo.h) like this:
334 OPENSSL_DECLARE_GLOBAL(int,foo);
335 #define foo OPENSSL_GLOBAL_REF(foo)
336 OPENSSL_DECLARE_GLOBAL(double,bar);
337 #define bar OPENSSL_GLOBAL_REF(bar)
339 The #defines are very important, and therefore so is including the
340 header file everywere where the defined globals are used.
342 The macro OPENSSL_EXPORT_VAR_AS_FUNCTION also affects the definition
343 of ASN.1 items, but that structure is a bt different.
345 The largest change is in util/mkdef.pl which has been enhanced with
346 better and easier to understand logic to choose which symbols should
347 go into the Windows .def files as well as a number of fixes and code
348 cleanup (among others, algorithm keywords are now sorted
349 lexicographically to avoid constant rewrites).
352 *) In copy_email() check for >= 0 as a return value for
353 X509_NAME_get_index_by_NID() since 0 is a valid index.
354 [Steve Henson reported by Massimiliano Pala <madwolf@opensca.org>]
356 +) In BN_div() keep a copy of the sign of 'num' before writing the
357 result to 'rm' because if rm==num the value will be overwritten
358 and produce the wrong result if 'num' is negative: this caused
359 problems with BN_mod() and BN_nnmod().
362 +) Function OCSP_request_verify(). This checks the signature on an
363 OCSP request and verifies the signer certificate. The signer
364 certificate is just checked for a generic purpose and OCSP request
368 +) Add OCSP_check_validity() function to check the validity of OCSP
369 responses. OCSP responses are prepared in real time and may only
370 be a few seconds old. Simply checking that the current time lies
371 between thisUpdate and nextUpdate max reject otherwise valid responses
372 caused by either OCSP responder or client clock innacuracy. Instead
373 we allow thisUpdate and nextUpdate to fall within a certain period of
374 the current time. The age of the response can also optionally be
375 checked. Two new options -validity_period and -status_age added to
379 +) If signature or public key algorithm is unrecognized print out its
380 OID rather that just UNKOWN.
383 *) Avoid coredump with unsupported or invalid public keys by checking if
384 X509_get_pubkey() fails in PKCS7_verify(). Fix memory leak when
385 PKCS7_verify() fails with non detached data.
388 +) Change OCSP_cert_to_id() to tolerate a NULL subject certificate and
389 OCSP_cert_id_new() a NULL serialNumber. This allows a partial certificate
390 ID to be generated from the issuer certificate alone which can then be
391 passed to OCSP_id_issuer_cmp().
394 +) New compilation option ASN1_ITEM_FUNCTIONS. This causes the new
395 ASN1 modules to export functions returning ASN1_ITEM pointers
396 instead of the ASN1_ITEM structures themselves. This adds several
397 new macros which allow the underlying ASN1 function/structure to
398 be accessed transparently. As a result code should not use ASN1_ITEM
399 references directly (such as &X509_it) but instead use the relevant
400 macros (such as ASN1_ITEM_rptr(X509)). This option is to allow
401 use of the new ASN1 code on platforms where exporting structures
402 is problematical (for example in shared libraries) but exporting
403 functions returning pointers to structures is not.
406 +) Add support for overriding the generation of SSL/TLS session IDs.
407 These callbacks can be registered either in an SSL_CTX or per SSL.
408 The purpose of this is to allow applications to control, if they wish,
409 the arbitrary values chosen for use as session IDs, particularly as it
410 can be useful for session caching in multiple-server environments. A
411 command-line switch for testing this (and any client code that wishes
412 to use such a feature) has been added to "s_server".
413 [Geoff Thorpe, Lutz Jaenicke]
415 +) Modify mkdef.pl to recognise and parse prprocessor conditionals
416 of the form '#if defined(...) || defined(...) || ...' and
417 '#if !defined(...) && !defined(...) && ...'. This also avoids
418 the growing number of special cases it was previously handling.
421 *) Don't use getenv in library functions when run as setuid/setgid.
422 New function OPENSSL_issetugid().
425 +) Make all configuration macros available for application by making
426 sure they are available in opensslconf.h, by giving them names starting
427 with "OPENSSL_" to avoid conflicts with other packages and by making
428 sure e_os2.h will cover all platform-specific cases together with
430 Additionally, it is now possible to define configuration/platform-
431 specific names (called "system identities"). In the C code, these
432 are prefixed with "OPENSSL_SYSNAME_". e_os2.h will create another
433 macro with the name beginning with "OPENSSL_SYS_", which is determined
434 from "OPENSSL_SYSNAME_*" or compiler-specific macros depending on
438 +) New option -set_serial to 'req' and 'x509' this allows the serial
439 number to use to be specified on the command line. Previously self
440 signed certificates were hard coded with serial number 0 and the
441 CA options of 'x509' had to use a serial number in a file which was
445 *) Avoid false positives in memory leak detection code (crypto/mem_dbg.c)
446 due to incorrect handling of multi-threading:
448 1. Fix timing glitch in the MemCheck_off() portion of CRYPTO_mem_ctrl().
450 2. Fix logical glitch in is_MemCheck_on() aka CRYPTO_is_mem_check_on().
452 3. Count how many times MemCheck_off() has been called so that
453 nested use can be treated correctly. This also avoids
454 inband-signalling in the previous code (which relied on the
455 assumption that thread ID 0 is impossible).
458 +) New options to 'ca' utility to support V2 CRL entry extensions.
459 Currently CRL reason, invalidity date and hold instruction are
460 supported. Add new CRL extensions to V3 code and some new objects.
463 *) Add "-rand" option also to s_client and s_server.
466 +) New function EVP_CIPHER_CTX_set_padding() this is used to
467 disable standard block padding (aka PKCS#5 padding) in the EVP
468 API, which was previously mandatory. This means that the data is
469 not padded in any way and so the total length much be a multiple
470 of the block size, otherwise an error occurs.
473 +) Initial (incomplete) OCSP SSL support.
476 *) Fix CPU detection on Irix 6.x.
477 [Kurt Hockenbury <khockenb@stevens-tech.edu> and
478 "Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
480 +) New function OCSP_parse_url(). This splits up a URL into its host,
481 port and path components: primarily to parse OCSP URLs. New -url
482 option to ocsp utility.
485 +) New nonce behavior. The return value of OCSP_check_nonce() now
486 reflects the various checks performed. Applications can decide
487 whether to tolerate certain situations such as an absent nonce
488 in a response when one was present in a request: the ocsp application
489 just prints out a warning. New function OCSP_add1_basic_nonce()
490 this is to allow responders to include a nonce in a response even if
491 the request is nonce-less.
494 *) Fix X509_NAME bug which produced incorrect encoding if X509_NAME
496 [This change does not apply to 0.9.7.]
498 *) Use the cached encoding of an X509_NAME structure rather than
499 copying it. This is apparently the reason for the libsafe "errors"
500 but the code is actually correct.
503 +) Disable stdin buffering in load_cert (apps/apps.c) so that no certs are
504 skipped when using openssl x509 multiple times on a single input file,
505 e.g. "(openssl x509 -out cert1; openssl x509 -out cert2) <certs".
508 +) Make ASN1_UTCTIME_set_string() and ASN1_GENERALIZEDTIME_set_string()
509 set string type: to handle setting ASN1_TIME structures. Fix ca
510 utility to correctly initialize revocation date of CRLs.
513 +) New option SSL_OP_CIPHER_SERVER_PREFERENCE allows the server to override
514 the clients preferred ciphersuites and rather use its own preferences.
515 Should help to work around M$ SGC (Server Gated Cryptography) bug in
516 Internet Explorer by ensuring unchanged hash method during stepup.
519 +) Make mkdef.pl recognise all DECLARE_ASN1 macros, change rijndael
520 to aes and add a new 'exist' option to print out symbols that don't
524 +) Additional options to ocsp utility to allow flags to be set and
525 additional certificates supplied.
528 +) Add the option -VAfile to 'openssl ocsp', so the user can give the
529 OCSP client a number of certificate to only verify the response
533 *) Add new function BN_rand_range(), and fix DSA_sign_setup() to prevent
534 Bleichenbacher's DSA attack.
535 Extend BN_[pseudo_]rand: As before, top=1 forces the highest two bits
536 to be set and top=0 forces the highest bit to be set; top=-1 is new
537 and leaves the highest bit random.
538 [Ulf Moeller, Bodo Moeller]
540 +) Update Rijndael code to version 3.0 and change EVP AES ciphers to
541 handle the new API. Currently only ECB, CBC modes supported. Add new
542 AES OIDs. Add TLS AES ciphersuites as described in the "AES Ciphersuites
543 for TLS" draft-ietf-tls-ciphersuite-03.txt.
544 [Ben Laurie, Steve Henson]
546 *) In the NCONF_...-based implementations for CONF_... queries
547 (crypto/conf/conf_lib.c), if the input LHASH is NULL, avoid using
548 a temporary CONF structure with the data component set to NULL
549 (which gives segmentation faults in lh_retrieve).
550 Instead, use NULL for the CONF pointer in CONF_get_string and
551 CONF_get_number (which may use environment variables) and directly
552 return NULL from CONF_get_section.
555 *) Fix potential buffer overrun for EBCDIC.
558 +) New function OCSP_copy_nonce() to copy nonce value (if present) from
562 +) Functions for OCSP responders. OCSP_request_onereq_count(),
563 OCSP_request_onereq_get0(), OCSP_onereq_get0_id() and OCSP_id_get0_info()
564 extract information from a certificate request. OCSP_response_create()
565 creates a response and optionally adds a basic response structure.
566 OCSP_basic_add1_status() adds a complete single response to a basic
567 reponse and returns the OCSP_SINGLERESP structure just added (to allow
568 extensions to be included for example). OCSP_basic_add1_cert() adds a
569 certificate to a basic response and OCSP_basic_sign() signs a basic
570 response with various flags. New helper functions ASN1_TIME_check()
571 (checks validity of ASN1_TIME structure) and ASN1_TIME_to_generalizedtime()
572 (converts ASN1_TIME to GeneralizedTime).
575 +) Various new functions. EVP_Digest() combines EVP_Digest{Init,Update,Final}()
576 in a single operation. X509_get0_pubkey_bitstr() extracts the public_key
577 structure from a certificate. X509_pubkey_digest() digests tha public_key
578 contents: this is used in various key identifiers.
581 *) Tolerate nonRepudiation as being valid for S/MIME signing and certSign
582 keyUsage if basicConstraints absent for a CA.
585 *) Make SMIME_write_PKCS7() write mail header values with a format that
586 is more generally accepted (no spaces before the semicolon), since
587 some programs can't parse those values properly otherwise. Also make
588 sure BIO's that break lines after each write do not create invalid
592 +) Make sk_sort() tolerate a NULL argument.
593 [Steve Henson reported by Massimiliano Pala <madwolf@comune.modena.it>]
595 +) New OCSP verify flag OCSP_TRUSTOTHER. When set the "other" certificates
596 passed by the function are trusted implicitly. If any of them signed the
597 reponse then it is assumed to be valid and is not verified.
600 -) Make the CRL encoding routines work with empty SEQUENCE OF. The
601 macros previously used would not encode an empty SEQUENCE OF
602 and break the signature.
604 [This change does not apply to 0.9.7.]
606 *) Zero the premaster secret after deriving the master secret in
610 +) In PKCS7_set_type() initialise content_type in PKCS7_ENC_CONTENT
611 to data. This was previously part of the PKCS7 ASN1 code. This
612 was causing problems with OpenSSL created PKCS#12 and PKCS#7 structures.
613 [Steve Henson, reported by Kenneth R. Robinette
614 <support@securenetterm.com>]
616 +) Add CRYPTO_push_info() and CRYPTO_pop_info() calls to new ASN1
617 routines: without these tracing memory leaks is very painful.
618 Fix leaks in PKCS12 and PKCS7 routines.
621 *) Add some EVP_add_digest_alias registrations (as found in
622 OpenSSL_add_all_digests()) to SSL_library_init()
623 aka OpenSSL_add_ssl_algorithms(). This provides improved
624 compatibility with peers using X.509 certificates
625 with unconventional AlgorithmIdentifier OIDs.
628 *) Fix for Irix with NO_ASM.
629 ["Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
631 *) ./config script fixes.
632 [Ulf Moeller, Richard Levitte]
634 +) Make X509_time_adj() cope with the new behaviour of ASN1_TIME_new().
635 Previously it initialised the 'type' argument to V_ASN1_UTCTIME which
636 effectively meant GeneralizedTime would never be used. Now it
637 is initialised to -1 but X509_time_adj() now has to check the value
638 and use ASN1_TIME_set() if the value is not V_ASN1_UTCTIME or
639 V_ASN1_GENERALIZEDTIME, without this it always uses GeneralizedTime.
640 [Steve Henson, reported by Kenneth R. Robinette
641 <support@securenetterm.com>]
643 +) Fixes to BN_to_ASN1_INTEGER when bn is zero. This would previously
644 result in a zero length in the ASN1_INTEGER structure which was
645 not consistent with the structure when d2i_ASN1_INTEGER() was used
646 and would cause ASN1_INTEGER_cmp() to fail. Enhance s2i_ASN1_INTEGER()
647 to cope with hex and negative integers. Fix bug in i2a_ASN1_INTEGER()
648 where it did not print out a minus for negative ASN1_INTEGER.
651 *) Fix 'openssl passwd -1'.
654 +) Add summary printout to ocsp utility. The various functions which
655 convert status values to strings have been renamed to:
656 OCSP_response_status_str(), OCSP_cert_status_str() and
657 OCSP_crl_reason_str() and are no longer static. New options
658 to verify nonce values and to disable verification. OCSP response
659 printout format cleaned up.
662 +) Add additional OCSP certificate checks. These are those specified
663 in RFC2560. This consists of two separate checks: the CA of the
664 certificate being checked must either be the OCSP signer certificate
665 or the issuer of the OCSP signer certificate. In the latter case the
666 OCSP signer certificate must contain the OCSP signing extended key
667 usage. This check is performed by attempting to match the OCSP
668 signer or the OCSP signer CA to the issuerNameHash and issuerKeyHash
669 in the OCSP_CERTID structures of the response.
672 +) Initial OCSP certificate verification added to OCSP_basic_verify()
673 and related routines. This uses the standard OpenSSL certificate
674 verify routines to perform initial checks (just CA validity) and
675 to obtain the certificate chain. Then additional checks will be
676 performed on the chain. Currently the root CA is checked to see
677 if it is explicitly trusted for OCSP signing. This is used to set
678 a root CA as a global signing root: that is any certificate that
679 chains to that CA is an acceptable OCSP signing certificate.
682 +) New '-extfile ...' option to 'openssl ca' for reading X.509v3
683 extensions from a separate configuration file.
684 As when reading extensions from the main configuration file,
685 the '-extensions ...' option may be used for specifying the
687 [Massimiliano Pala <madwolf@comune.modena.it>]
689 *) Change PKCS12_key_gen_asc() so it can cope with non null
690 terminated strings whose length is passed in the passlen
691 parameter, for example from PEM callbacks. This was done
692 by adding an extra length parameter to asc2uni().
693 [Steve Henson, reported by <oddissey@samsung.co.kr>]
695 +) New OCSP utility. Allows OCSP requests to be generated or
696 read. The request can be sent to a responder and the output
697 parsed, outputed or printed in text form. Not complete yet:
698 still needs to check the OCSP response validity.
701 +) New subcommands for 'openssl ca':
702 'openssl ca -status <serial>' prints the status of the cert with
703 the given serial number (according to the index file).
704 'openssl ca -updatedb' updates the expiry status of certificates
706 [Massimiliano Pala <madwolf@comune.modena.it>]
708 +) New '-newreq-nodes' command option to CA.pl. This is like
709 '-newreq', but calls 'openssl req' with the '-nodes' option
710 so that the resulting key is not encrypted.
711 [Damien Miller <djm@mindrot.org>]
713 +) New configuration for the GNU Hurd.
714 [Jonathan Bartlett <johnnyb@wolfram.com> via Richard Levitte]
716 +) Initial code to implement OCSP basic response verify. This
717 is currently incomplete. Currently just finds the signer's
718 certificate and verifies the signature on the response.
721 +) New SSLeay_version code SSLEAY_DIR to determine the compiled-in
722 value of OPENSSLDIR. This is available via the new '-d' option
723 to 'openssl version', and is also included in 'openssl version -a'.
726 *) Fix C code generated by 'openssl dsaparam -C': If a BN_bin2bn
727 call failed, free the DSA structure.
730 +) Allowing defining memory allocation callbacks that will be given
731 file name and line number information in additional arguments
732 (a const char* and an int). The basic functionality remains, as
733 well as the original possibility to just replace malloc(),
734 realloc() and free() by functions that do not know about these
735 additional arguments. To register and find out the current
736 settings for extended allocation functions, the following
737 functions are provided:
739 CRYPTO_set_mem_ex_functions
740 CRYPTO_set_locked_mem_ex_functions
741 CRYPTO_get_mem_ex_functions
742 CRYPTO_get_locked_mem_ex_functions
744 These work the same way as CRYPTO_set_mem_functions and friends.
745 CRYPTO_get_[locked_]mem_functions now writes 0 where such an
746 extended allocation function is enabled.
747 Similarly, CRYPTO_get_[locked_]mem_ex_functions writes 0 where
748 a conventional allocation function is enabled.
749 [Richard Levitte, Bodo Moeller]
751 *) Fix to uni2asc() to cope with zero length Unicode strings.
752 These are present in some PKCS#12 files.
755 +) Finish off removing the remaining LHASH function pointer casts.
756 There should no longer be any prototype-casting required when using
757 the LHASH abstraction, and any casts that remain are "bugs". See
758 the callback types and macros at the head of lhash.h for details
759 (and "OBJ_cleanup" in crypto/objects/obj_dat.c as an example).
762 +) Add automatic query of EGD sockets in RAND_poll() for the unix variant.
763 If an EGD or PRNGD is running and enough entropy is returned, automatic
764 seeding like with /dev/[u]random will be performed.
765 Positions tried are: /etc/entropy, /var/run/egd-pool.
768 +) Change the Unix RAND_poll() variant to be able to poll several
769 random devices, as specified by DEVRANDOM, until a sufficient amount
770 of data has been collected. We spend at most 10 ms on each file
771 (select timeout) and read in non-blocking mode. DEVRANDOM now
772 defaults to the list "/dev/urandom", "/dev/random", "/dev/srandom"
773 (previously it was just the string "/dev/urandom"), so on typical
774 platforms the 10 ms delay will never occur.
775 Also separate out the Unix variant to its own file, rand_unix.c.
776 For VMS, there's a currently-empty rand_vms.c.
779 +) Move OCSP client related routines to ocsp_cl.c. These
780 provide utility functions which an application needing
781 to issue a request to an OCSP responder and analyse the
782 response will typically need: as opposed to those which an
783 OCSP responder itself would need which will be added later.
785 OCSP_request_sign() signs an OCSP request with an API similar
786 to PKCS7_sign(). OCSP_response_status() returns status of OCSP
787 response. OCSP_response_get1_basic() extracts basic response
788 from response. OCSP_resp_find_status(): finds and extracts status
789 information from an OCSP_CERTID structure (which will be created
790 when the request structure is built). These are built from lower
791 level functions which work on OCSP_SINGLERESP structures but
792 wont normally be used unless the application wishes to examine
793 extensions in the OCSP response for example.
795 Replace nonce routines with a pair of functions.
796 OCSP_request_add1_nonce() adds a nonce value and optionally
797 generates a random value. OCSP_check_nonce() checks the
798 validity of the nonce in an OCSP response.
801 +) Change function OCSP_request_add() to OCSP_request_add0_id().
802 This doesn't copy the supplied OCSP_CERTID and avoids the
803 need to free up the newly created id. Change return type
804 to OCSP_ONEREQ to return the internal OCSP_ONEREQ structure.
805 This can then be used to add extensions to the request.
806 Deleted OCSP_request_new(), since most of its functionality
807 is now in OCSP_REQUEST_new() (and the case insensitive name
808 clash) apart from the ability to set the request name which
809 will be added elsewhere.
812 +) Update OCSP API. Remove obsolete extensions argument from
813 various functions. Extensions are now handled using the new
814 OCSP extension code. New simple OCSP HTTP function which
815 can be used to send requests and parse the response.
818 +) Fix the PKCS#7 (S/MIME) code to work with new ASN1. Two new
819 ASN1_ITEM structures help with sign and verify. PKCS7_ATTR_SIGN
820 uses the special reorder version of SET OF to sort the attributes
821 and reorder them to match the encoded order. This resolves a long
822 standing problem: a verify on a PKCS7 structure just after signing
823 it used to fail because the attribute order did not match the
824 encoded order. PKCS7_ATTR_VERIFY does not reorder the attributes:
825 it uses the received order. This is necessary to tolerate some broken
826 software that does not order SET OF. This is handled by encoding
827 as a SEQUENCE OF but using implicit tagging (with UNIVERSAL class)
828 to produce the required SET OF.
831 +) Have mk1mf.pl generate the macros OPENSSL_BUILD_SHLIBCRYPTO and
832 OPENSSL_BUILD_SHLIBSSL and use them appropriately in the header
833 files to get correct declarations of the ASN.1 item variables.
836 +) Rewrite of PKCS#12 code to use new ASN1 functionality. Replace many
837 PKCS#12 macros with real functions. Fix two unrelated ASN1 bugs:
838 asn1_check_tlen() would sometimes attempt to use 'ctx' when it was
839 NULL and ASN1_TYPE was not dereferenced properly in asn1_ex_c2i().
840 New ASN1 macro: DECLARE_ASN1_ITEM() which just declares the relevant
841 ASN1_ITEM and no wrapper functions.
844 +) New functions or ASN1_item_d2i_fp() and ASN1_item_d2i_bio(). These
845 replace the old function pointer based I/O routines. Change most of
846 the *_d2i_bio() and *_d2i_fp() functions to use these.
849 +) Enhance mkdef.pl to be more accepting about spacing in C preprocessor
850 lines, recognice more "algorithms" that can be deselected, and make
851 it complain about algorithm deselection that isn't recognised.
854 +) New ASN1 functions to handle dup, sign, verify, digest, pack and
855 unpack operations in terms of ASN1_ITEM. Modify existing wrappers
856 to use new functions. Add NO_ASN1_OLD which can be set to remove
857 some old style ASN1 functions: this can be used to determine if old
858 code will still work when these eventually go away.
861 +) New extension functions for OCSP structures, these follow the
862 same conventions as certificates and CRLs.
865 +) New function X509V3_add1_i2d(). This automatically encodes and
866 adds an extension. Its behaviour can be customised with various
867 flags to append, replace or delete. Various wrappers added for
868 certifcates and CRLs.
871 +) Fix to avoid calling the underlying ASN1 print routine when
872 an extension cannot be parsed. Correct a typo in the
873 OCSP_SERVICELOC extension. Tidy up print OCSP format.
876 *) Increase s2->wbuf allocation by one byte in ssl2_new (ssl/s2_lib.c).
877 Otherwise do_ssl_write (ssl/s2_pkt.c) will write beyond buffer limits
878 when writing a 32767 byte record.
879 [Bodo Moeller; problem reported by Eric Day <eday@concentric.net>]
881 *) In RSA_eay_public_{en,ed}crypt and RSA_eay_mod_exp (rsa_eay.c),
882 obtain lock CRYPTO_LOCK_RSA before setting rsa->_method_mod_{n,p,q}.
884 (RSA objects have a reference count access to which is protected
885 by CRYPTO_LOCK_RSA [see rsa_lib.c, s3_srvr.c, ssl_cert.c, ssl_rsa.c],
886 so they are meant to be shared between threads.)
887 [Bodo Moeller, Geoff Thorpe; original patch submitted by
888 "Reddie, Steven" <Steven.Reddie@ca.com>]
890 +) Make mkdef.pl parse some of the ASN1 macros and add apropriate
891 entries for variables.
894 *) Fix a deadlock in CRYPTO_mem_leaks().
897 +) Add functionality to apps/openssl.c for detecting locking
898 problems: As the program is single-threaded, all we have
899 to do is register a locking callback using an array for
900 storing which locks are currently held by the program.
903 +) Use a lock around the call to CRYPTO_get_ex_new_index() in
904 SSL_get_ex_data_X509_STORE_idx(), which is used in
905 ssl_verify_cert_chain() and thus can be called at any time
906 during TLS/SSL handshakes so that thread-safety is essential.
907 Unfortunately, the ex_data design is not at all suited
908 for multi-threaded use, so it probably should be abolished.
911 +) Added Broadcom "ubsec" ENGINE to OpenSSL.
912 [Broadcom, tweaked and integrated by Geoff Thorpe]
914 +) Move common extension printing code to new function
915 X509V3_print_extensions(). Reorganise OCSP print routines and
916 implement some needed OCSP ASN1 functions. Add OCSP extensions.
919 +) New function X509_signature_print() to remove duplication in some
923 +) Add a special meaning when SET OF and SEQUENCE OF flags are both
924 set (this was treated exactly the same as SET OF previously). This
925 is used to reorder the STACK representing the structure to match the
926 encoding. This will be used to get round a problem where a PKCS7
927 structure which was signed could not be verified because the STACK
928 order did not reflect the encoded order.
931 +) Reimplement the OCSP ASN1 module using the new code.
934 +) Update the X509V3 code to permit the use of an ASN1_ITEM structure
935 for its ASN1 operations. The old style function pointers still exist
936 for now but they will eventually go away.
939 +) Merge in replacement ASN1 code from the ASN1 branch. This almost
940 completely replaces the old ASN1 functionality with a table driven
941 encoder and decoder which interprets an ASN1_ITEM structure describing
942 the ASN1 module. Compatibility with the existing ASN1 API (i2d,d2i) is
943 largely maintained. Almost all of the old asn1_mac.h macro based ASN1
944 has also been converted to the new form.
947 +) Change BN_mod_exp_recp so that negative moduli are tolerated
948 (the sign is ignored). Similarly, ignore the sign in BN_MONT_CTX_set
949 so that BN_mod_exp_mont and BN_mod_exp_mont_word work
953 +) Fix BN_uadd and BN_usub: Always return non-negative results instead
954 of not touching the result's sign bit.
957 +) BN_div bugfix: If the result is 0, the sign (res->neg) must not be
961 +) Changed the LHASH code to use prototypes for callbacks, and created
962 macros to declare and implement thin (optionally static) functions
963 that provide type-safety and avoid function pointer casting for the
964 type-specific callbacks.
967 *) Use better test patterns in bntest.
970 +) Added Kerberos Cipher Suites to be used with TLS, as written in
972 [Veers Staats <staatsvr@asc.hpc.mil>,
973 Jeffrey Altman <jaltman@columbia.edu>, via Richard Levitte]
975 *) rand_win.c fix for Borland C.
978 *) BN_rshift bugfix for n == 0.
981 +) Reformat the FAQ so the different questions and answers can be divided
982 in sections depending on the subject.
985 +) Have the zlib compression code load ZLIB.DLL dynamically under
989 +) New function BN_mod_sqrt for computing square roots modulo a prime
990 (using the probabilistic Tonelli-Shanks algorithm unless
991 p == 3 (mod 4) or p == 5 (mod 8), which are cases that can
992 be handled deterministically).
993 [Lenka Fibikova <fibikova@exp-math.uni-essen.de>, Bodo Moeller]
995 *) Add a 'bctest' script that checks for some known 'bc' bugs
996 so that 'make test' does not abort just because 'bc' is broken.
999 *) Store verify_result within SSL_SESSION also for client side to
1000 avoid potential security hole. (Re-used sessions on the client side
1001 always resulted in verify_result==X509_V_OK, not using the original
1002 result of the server certificate verification.)
1005 +) Make BN_mod_inverse faster by explicitly handling small quotients
1006 in the Euclid loop. (Speed gain about 20% for small moduli [256 or
1007 512 bits], about 30% for larger ones [1024 or 2048 bits].)
1010 *) Fix ssl3_pending: If the record in s->s3->rrec is not of type
1011 SSL3_RT_APPLICATION_DATA, return 0.
1012 Similarly, change ssl2_pending to return 0 if SSL_in_init(s) is true.
1016 Both ssl2_peek and ssl3_peek, which were totally broken in earlier
1017 releases, have been re-implemented by renaming the previous
1018 implementations of ssl2_read and ssl3_read to ssl2_read_internal
1019 and ssl3_read_internal, respectively, and adding 'peek' parameters
1020 to them. The new ssl[23]_{read,peek} functions are calls to
1021 ssl[23]_read_internal with the 'peek' flag set appropriately.
1022 A 'peek' parameter has also been added to ssl3_read_bytes, which
1023 does the actual work for ssl3_read_internal.
1026 +) New function BN_kronecker.
1029 +) Fix BN_gcd so that it works on negative inputs; the result is
1030 positive unless both parameters are zero.
1031 Previously something reasonably close to an infinite loop was
1032 possible because numbers could be growing instead of shrinking
1033 in the implementation of Euclid's algorithm.
1036 +) Fix BN_is_word() and BN_is_one() macros to take into account the
1037 sign of the number in question.
1039 Fix BN_is_word(a,w) to work correctly for w == 0.
1041 The old BN_is_word(a,w) macro is now called BN_abs_is_word(a,w)
1042 because its test if the absolute value of 'a' equals 'w'.
1043 Note that BN_abs_is_word does *not* handle w == 0 reliably;
1044 it exists mostly for use in the implementations of BN_is_zero(),
1045 BN_is_one(), and BN_is_word().
1048 *) Initialise "ex_data" member of RSA/DSA/DH structures prior to calling
1049 the method-specific "init()" handler. Also clean up ex_data after
1050 calling the method-specific "finish()" handler. Previously, this was
1051 happening the other way round.
1054 +) New function BN_swap.
1057 +) Use BN_nnmod instead of BN_mod in crypto/bn/bn_exp.c so that
1058 the exponentiation functions are more likely to produce reasonable
1059 results on negative inputs.
1062 +) Change BN_mod_mul so that the result is always non-negative.
1063 Previously, it could be negative if one of the factors was negative;
1064 I don't think anyone really wanted that behaviour.
1067 +) Move BN_mod_... functions into new file crypto/bn/bn_mod.c
1068 (except for exponentiation, which stays in crypto/bn/bn_exp.c,
1069 and BN_mod_mul_reciprocal, which stays in crypto/bn/bn_recp.c)
1070 and add new functions:
1079 BN_mod_lshift1_quick
1083 These functions always generate non-negative results.
1085 BN_nnmod otherwise is like BN_mod (if BN_mod computes a remainder r
1086 such that |m| < r < 0, BN_nnmod will output rem + |m| instead).
1088 BN_mod_XXX_quick(r, a, [b,] m) generates the same result as
1089 BN_mod_XXX(r, a, [b,] m, ctx), but requires that a [and b]
1090 be reduced modulo m.
1091 [Lenka Fibikova <fibikova@exp-math.uni-essen.de>, Bodo Moeller]
1093 +) Remove a few calls to bn_wexpand() in BN_sqr() (the one in there
1094 was actually never needed) and in BN_mul(). The removal in BN_mul()
1095 required a small change in bn_mul_part_recursive() and the addition
1096 of the functions bn_cmp_part_words(), bn_sub_part_words() and
1097 bn_add_part_words(), which do the same thing as bn_cmp_words(),
1098 bn_sub_words() and bn_add_words() except they take arrays with
1102 +) In 'openssl passwd', verify passwords read from the terminal
1103 unless the '-salt' option is used (which usually means that
1104 verification would just waste user's time since the resulting
1105 hash is going to be compared with some given password hash)
1106 or the new '-noverify' option is used.
1108 This is an incompatible change, but it does not affect
1109 non-interactive use of 'openssl passwd' (passwords on the command
1110 line, '-stdin' option, '-in ...' option) and thus should not
1114 +) Remove all references to RSAref, since there's no more need for it.
1117 *) Increase BN_CTX_NUM (the number of BIGNUMs in a BN_CTX) to 16.
1118 The previous value, 12, was not always sufficient for BN_mod_exp().
1121 +) Make DSO load along a path given through an environment variable
1122 (SHLIB_PATH) with shl_load().
1125 +) Constify the ENGINE code as a result of BIGNUM constification.
1126 Also constify the RSA code and most things related to it. In a
1127 few places, most notable in the depth of the ASN.1 code, ugly
1128 casts back to non-const were required (to be solved at a later
1132 +) Make it so the openssl application has all engines loaded by default.
1135 +) Constify the BIGNUM routines a little more.
1138 *) Make sure that shared libraries get the internal name engine with
1139 the full version number and not just 0. This should mark the
1140 shared libraries as not backward compatible. Of course, this should
1141 be changed again when we can guarantee backward binary compatibility.
1144 +) Add the following functions:
1146 ENGINE_load_cswift()
1148 ENGINE_load_atalla()
1150 ENGINE_load_builtin_engines()
1152 That way, an application can itself choose if external engines that
1153 are built-in in OpenSSL shall ever be used or not. The benefit is
1154 that applications won't have to be linked with libdl or other dso
1155 libraries unless it's really needed.
1157 Changed 'openssl engine' to load all engines on demand.
1158 Changed the engine header files to avoid the duplication of some
1159 declarations (they differed!).
1162 +) 'openssl engine' can now list capabilities.
1165 +) Better error reporting in 'openssl engine'.
1168 +) Never call load_dh_param(NULL) in s_server.
1171 +) Add engine application. It can currently list engines by name and
1172 identity, and test if they are actually available.
1175 +) Add support for shared libraries under Irix.
1176 [Albert Chin-A-Young <china@thewrittenword.com>]
1178 +) Improve RPM specification file by forcing symbolic linking and making
1179 sure the installed documentation is also owned by root.root.
1180 [Damien Miller <djm@mindrot.org>]
1182 +) Add configuration option to build on Linux on both big-endian and
1184 [Ralf Baechle <ralf@uni-koblenz.de>]
1186 +) Give the OpenSSL applications more possibilities to make use of
1187 keys (public as well as private) handled by engines.
1190 +) Add OCSP code that comes from CertCo.
1193 +) Add VMS support for the Rijndael code.
1196 +) Added untested support for Nuron crypto accelerator.
1199 +) Add support for external cryptographic devices. This code was
1200 previously distributed separately as the "engine" branch.
1201 [Geoff Thorpe, Richard Levitte]
1203 +) Rework the filename-translation in the DSO code. It is now possible to
1204 have far greater control over how a "name" is turned into a filename
1205 depending on the operating environment and any oddities about the
1206 different shared library filenames on each system.
1209 +) Support threads on FreeBSD-elf in Configure.
1212 +) Add the possibility to create shared libraries on HP-UX
1215 +) Fix for SHA1 assembly problem with MASM: it produces
1216 warnings about corrupt line number information when assembling
1217 with debugging information. This is caused by the overlapping
1219 [Bernd Matthes <mainbug@celocom.de>, Steve Henson]
1222 NCONF_get_number() has no error checking at all. As a replacement,
1223 NCONF_get_number_e() is defined (_e for "error checking") and is
1224 promoted strongly. The old NCONF_get_number is kept around for
1225 binary backward compatibility.
1226 Make it possible for methods to load from something other than a BIO,
1227 by providing a function pointer that is given a name instead of a BIO.
1228 For example, this could be used to load configuration data from an
1232 *) Fix typo in get_cert_by_subject() in by_dir.c
1233 [Jean-Marc Desperrier <jean-marc.desperrier@certplus.com>]
1235 *) Rework the system to generate shared libraries:
1237 - Make note of the expected extension for the shared libraries and
1238 if there is a need for symbolic links from for example libcrypto.so.0
1239 to libcrypto.so.0.9.7. There is extended info in Configure for
1242 - Make as few rebuilds of the shared libraries as possible.
1244 - Still avoid linking the OpenSSL programs with the shared libraries.
1246 - When installing, install the shared libraries separately from the
1250 +) Fix for non blocking accept BIOs. Added new I/O special reason
1251 BIO_RR_ACCEPT to cover this case. Previously use of accept BIOs
1252 with non blocking I/O was not possible because no retry code was
1253 implemented. Also added new SSL code SSL_WANT_ACCEPT to cover
1257 +) Added the beginnings of Rijndael support.
1260 +) Fix for bug in DirectoryString mask setting. Add support for
1261 X509_NAME_print_ex() in 'req' and X509_print_ex() function
1262 to allow certificate printing to more controllable, additional
1263 'certopt' option to 'x509' to allow new printing options to be
1267 +) Clean old EAY MD5 hack from e_os.h.
1270 *) Fix SSL_CTX_set_read_ahead macro to actually use its argument.
1272 Copy SSL_CTX's read_ahead flag to SSL object directly in SSL_new
1273 and not in SSL_clear because the latter is also used by the
1274 accept/connect functions; previously, the settings made by
1275 SSL_set_read_ahead would be lost during the handshake.
1276 [Bodo Moeller; problems reported by Anders Gertz <gertz@epact.se>]
1278 *) Correct util/mkdef.pl to be selective about disabled algorithms.
1279 Previously, it would create entries for disableed algorithms no
1283 *) Added several new manual pages for SSL_* function.
1286 Changes between 0.9.5a and 0.9.6 [24 Sep 2000]
1288 *) In ssl23_get_client_hello, generate an error message when faced
1289 with an initial SSL 3.0/TLS record that is too small to contain the
1290 first two bytes of the ClientHello message, i.e. client_version.
1291 (Note that this is a pathologic case that probably has never happened
1292 in real life.) The previous approach was to use the version number
1293 from the record header as a substitute; but our protocol choice
1294 should not depend on that one because it is not authenticated
1295 by the Finished messages.
1298 *) More robust randomness gathering functions for Windows.
1299 [Jeffrey Altman <jaltman@columbia.edu>]
1301 *) For compatibility reasons if the flag X509_V_FLAG_ISSUER_CHECK is
1302 not set then we don't setup the error code for issuer check errors
1303 to avoid possibly overwriting other errors which the callback does
1304 handle. If an application does set the flag then we assume it knows
1305 what it is doing and can handle the new informational codes
1309 *) Fix for a nasty bug in ASN1_TYPE handling. ASN1_TYPE is used for
1310 a general "ANY" type, as such it should be able to decode anything
1311 including tagged types. However it didn't check the class so it would
1312 wrongly interpret tagged types in the same way as their universal
1313 counterpart and unknown types were just rejected. Changed so that the
1314 tagged and unknown types are handled in the same way as a SEQUENCE:
1315 that is the encoding is stored intact. There is also a new type
1316 "V_ASN1_OTHER" which is used when the class is not universal, in this
1317 case we have no idea what the actual type is so we just lump them all
1321 *) On VMS, stdout may very well lead to a file that is written to
1322 in a record-oriented fashion. That means that every write() will
1323 write a separate record, which will be read separately by the
1324 programs trying to read from it. This can be very confusing.
1326 The solution is to put a BIO filter in the way that will buffer
1327 text until a linefeed is reached, and then write everything a
1328 line at a time, so every record written will be an actual line,
1329 not chunks of lines and not (usually doesn't happen, but I've
1330 seen it once) several lines in one record. BIO_f_linebuffer() is
1333 Currently, it's a VMS-only method, because that's where it has
1334 been tested well enough.
1337 *) Remove 'optimized' squaring variant in BN_mod_mul_montgomery,
1338 it can return incorrect results.
1339 (Note: The buggy variant was not enabled in OpenSSL 0.9.5a,
1340 but it was in 0.9.6-beta[12].)
1343 *) Disable the check for content being present when verifying detached
1344 signatures in pk7_smime.c. Some versions of Netscape (wrongly)
1345 include zero length content when signing messages.
1348 *) New BIO_shutdown_wr macro, which invokes the BIO_C_SHUTDOWN_WR
1349 BIO_ctrl (for BIO pairs).
1352 *) Add DSO method for VMS.
1355 *) Bug fix: Montgomery multiplication could produce results with the
1359 *) Add RPM specification openssl.spec and modify it to build three
1360 packages. The default package contains applications, application
1361 documentation and run-time libraries. The devel package contains
1362 include files, static libraries and function documentation. The
1363 doc package contains the contents of the doc directory. The original
1364 openssl.spec was provided by Damien Miller <djm@mindrot.org>.
1367 *) Add a large number of documentation files for many SSL routines.
1368 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
1370 *) Add a configuration entry for Sony News 4.
1371 [NAKAJI Hiroyuki <nakaji@tutrp.tut.ac.jp>]
1373 *) Don't set the two most significant bits to one when generating a
1374 random number < q in the DSA library.
1377 *) New SSL API mode 'SSL_MODE_AUTO_RETRY'. This disables the default
1378 behaviour that SSL_read may result in SSL_ERROR_WANT_READ (even if
1379 the underlying transport is blocking) if a handshake took place.
1380 (The default behaviour is needed by applications such as s_client
1381 and s_server that use select() to determine when to use SSL_read;
1382 but for applications that know in advance when to expect data, it
1383 just makes things more complicated.)
1386 *) Add RAND_egd_bytes(), which gives control over the number of bytes read
1390 *) Add a few more EBCDIC conditionals that make `req' and `x509'
1391 work better on such systems.
1392 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
1394 *) Add two demo programs for PKCS12_parse() and PKCS12_create().
1395 Update PKCS12_parse() so it copies the friendlyName and the
1396 keyid to the certificates aux info.
1399 *) Fix bug in PKCS7_verify() which caused an infinite loop
1400 if there was more than one signature.
1401 [Sven Uszpelkat <su@celocom.de>]
1403 *) Major change in util/mkdef.pl to include extra information
1404 about each symbol, as well as presentig variables as well
1405 as functions. This change means that there's n more need
1406 to rebuild the .num files when some algorithms are excluded.
1409 *) Allow the verify time to be set by an application,
1410 rather than always using the current time.
1413 *) Phase 2 verify code reorganisation. The certificate
1414 verify code now looks up an issuer certificate by a
1415 number of criteria: subject name, authority key id
1416 and key usage. It also verifies self signed certificates
1417 by the same criteria. The main comparison function is
1418 X509_check_issued() which performs these checks.
1420 Lot of changes were necessary in order to support this
1421 without completely rewriting the lookup code.
1423 Authority and subject key identifier are now cached.
1425 The LHASH 'certs' is X509_STORE has now been replaced
1426 by a STACK_OF(X509_OBJECT). This is mainly because an
1427 LHASH can't store or retrieve multiple objects with
1428 the same hash value.
1430 As a result various functions (which were all internal
1431 use only) have changed to handle the new X509_STORE
1432 structure. This will break anything that messed round
1433 with X509_STORE internally.
1435 The functions X509_STORE_add_cert() now checks for an
1436 exact match, rather than just subject name.
1438 The X509_STORE API doesn't directly support the retrieval
1439 of multiple certificates matching a given criteria, however
1440 this can be worked round by performing a lookup first
1441 (which will fill the cache with candidate certificates)
1442 and then examining the cache for matches. This is probably
1443 the best we can do without throwing out X509_LOOKUP
1444 entirely (maybe later...).
1446 The X509_VERIFY_CTX structure has been enhanced considerably.
1448 All certificate lookup operations now go via a get_issuer()
1449 callback. Although this currently uses an X509_STORE it
1450 can be replaced by custom lookups. This is a simple way
1451 to bypass the X509_STORE hackery necessary to make this
1452 work and makes it possible to use more efficient techniques
1453 in future. A very simple version which uses a simple
1454 STACK for its trusted certificate store is also provided
1455 using X509_STORE_CTX_trusted_stack().
1457 The verify_cb() and verify() callbacks now have equivalents
1458 in the X509_STORE_CTX structure.
1460 X509_STORE_CTX also has a 'flags' field which can be used
1461 to customise the verify behaviour.
1464 *) Add new PKCS#7 signing option PKCS7_NOSMIMECAP which
1465 excludes S/MIME capabilities.
1468 *) When a certificate request is read in keep a copy of the
1469 original encoding of the signed data and use it when outputing
1470 again. Signatures then use the original encoding rather than
1471 a decoded, encoded version which may cause problems if the
1472 request is improperly encoded.
1475 *) For consistency with other BIO_puts implementations, call
1476 buffer_write(b, ...) directly in buffer_puts instead of calling
1479 In BIO_puts, increment b->num_write as in BIO_write.
1480 [Peter.Sylvester@EdelWeb.fr]
1482 *) Fix BN_mul_word for the case where the word is 0. (We have to use
1483 BN_zero, we may not return a BIGNUM with an array consisting of
1487 *) Avoid calling abort() from within the library when problems are
1488 detected, except if preprocessor symbols have been defined
1489 (such as REF_CHECK, BN_DEBUG etc.).
1492 *) New openssl application 'rsautl'. This utility can be
1493 used for low level RSA operations. DER public key
1494 BIO/fp routines also added.
1497 *) New Configure entry and patches for compiling on QNX 4.
1498 [Andreas Schneider <andreas@ds3.etech.fh-hamburg.de>]
1500 *) A demo state-machine implementation was sponsored by
1501 Nuron (http://www.nuron.com/) and is now available in
1502 demos/state_machine.
1505 *) New options added to the 'dgst' utility for signature
1506 generation and verification.
1509 *) Unrecognized PKCS#7 content types are now handled via a
1510 catch all ASN1_TYPE structure. This allows unsupported
1511 types to be stored as a "blob" and an application can
1512 encode and decode it manually.
1515 *) Fix various signed/unsigned issues to make a_strex.c
1517 [Oscar Jacobsson <oscar.jacobsson@celocom.com>]
1519 *) ASN1 fixes. i2d_ASN1_OBJECT was not returning the correct
1520 length if passed a buffer. ASN1_INTEGER_to_BN failed
1521 if passed a NULL BN and its argument was negative.
1522 [Steve Henson, pointed out by Sven Heiberg <sven@tartu.cyber.ee>]
1524 *) Modification to PKCS#7 encoding routines to output definite
1525 length encoding. Since currently the whole structures are in
1526 memory there's not real point in using indefinite length
1527 constructed encoding. However if OpenSSL is compiled with
1528 the flag PKCS7_INDEFINITE_ENCODING the old form is used.
1531 *) Added BIO_vprintf() and BIO_vsnprintf().
1534 *) Added more prefixes to parse for in the the strings written
1535 through a logging bio, to cover all the levels that are available
1536 through syslog. The prefixes are now:
1538 PANIC, EMERG, EMR => LOG_EMERG
1539 ALERT, ALR => LOG_ALERT
1540 CRIT, CRI => LOG_CRIT
1541 ERROR, ERR => LOG_ERR
1542 WARNING, WARN, WAR => LOG_WARNING
1543 NOTICE, NOTE, NOT => LOG_NOTICE
1544 INFO, INF => LOG_INFO
1545 DEBUG, DBG => LOG_DEBUG
1547 and as before, if none of those prefixes are present at the
1548 beginning of the string, LOG_ERR is chosen.
1550 On Win32, the LOG_* levels are mapped according to this:
1552 LOG_EMERG, LOG_ALERT, LOG_CRIT, LOG_ERR => EVENTLOG_ERROR_TYPE
1553 LOG_WARNING => EVENTLOG_WARNING_TYPE
1554 LOG_NOTICE, LOG_INFO, LOG_DEBUG => EVENTLOG_INFORMATION_TYPE
1558 *) Made it possible to reconfigure with just the configuration
1559 argument "reconf" or "reconfigure". The command line arguments
1560 are stored in Makefile.ssl in the variable CONFIGURE_ARGS,
1561 and are retrieved from there when reconfiguring.
1565 [Assar Westerlund <assar@sics.se>, Richard Levitte]
1567 *) Add the arguments -CAfile and -CApath to the pkcs12 utility.
1570 *) The obj_dat.pl script was messing up the sorting of object
1571 names. The reason was that it compared the quoted version
1572 of strings as a result "OCSP" > "OCSP Signing" because
1573 " > SPACE. Changed script to store unquoted versions of
1574 names and add quotes on output. It was also omitting some
1575 names from the lookup table if they were given a default
1576 value (that is if SN is missing it is given the same
1577 value as LN and vice versa), these are now added on the
1578 grounds that if an object has a name we should be able to
1579 look it up. Finally added warning output when duplicate
1580 short or long names are found.
1583 *) Changes needed for Tandem NSK.
1584 [Scott Uroff <scott@xypro.com>]
1586 *) Fix SSL 2.0 rollback checking: Due to an off-by-one error in
1587 RSA_padding_check_SSLv23(), special padding was never detected
1588 and thus the SSL 3.0/TLS 1.0 countermeasure against protocol
1589 version rollback attacks was not effective.
1591 In s23_clnt.c, don't use special rollback-attack detection padding
1592 (RSA_SSLV23_PADDING) if SSL 2.0 is the only protocol enabled in the
1593 client; similarly, in s23_srvr.c, don't do the rollback check if
1594 SSL 2.0 is the only protocol enabled in the server.
1597 *) Make it possible to get hexdumps of unprintable data with 'openssl
1598 asn1parse'. By implication, the functions ASN1_parse_dump() and
1599 BIO_dump_indent() are added.
1602 *) New functions ASN1_STRING_print_ex() and X509_NAME_print_ex()
1603 these print out strings and name structures based on various
1604 flags including RFC2253 support and proper handling of
1605 multibyte characters. Added options to the 'x509' utility
1606 to allow the various flags to be set.
1609 *) Various fixes to use ASN1_TIME instead of ASN1_UTCTIME.
1610 Also change the functions X509_cmp_current_time() and
1611 X509_gmtime_adj() work with an ASN1_TIME structure,
1612 this will enable certificates using GeneralizedTime in validity
1613 dates to be checked.
1616 *) Make the NEG_PUBKEY_BUG code (which tolerates invalid
1617 negative public key encodings) on by default,
1618 NO_NEG_PUBKEY_BUG can be set to disable it.
1621 *) New function c2i_ASN1_OBJECT() which acts on ASN1_OBJECT
1622 content octets. An i2c_ASN1_OBJECT is unnecessary because
1623 the encoding can be trivially obtained from the structure.
1626 *) crypto/err.c locking bugfix: Use write locks (CRYPTO_w_[un]lock),
1627 not read locks (CRYPTO_r_[un]lock).
1630 *) A first attempt at creating official support for shared
1631 libraries through configuration. I've kept it so the
1632 default is static libraries only, and the OpenSSL programs
1633 are always statically linked for now, but there are
1634 preparations for dynamic linking in place.
1635 This has been tested on Linux and True64.
1638 *) Randomness polling function for Win9x, as described in:
1639 Peter Gutmann, Software Generation of Practically Strong
1643 *) Fix so PRNG is seeded in req if using an already existing
1647 *) New options to smime application. -inform and -outform
1648 allow alternative formats for the S/MIME message including
1649 PEM and DER. The -content option allows the content to be
1650 specified separately. This should allow things like Netscape
1651 form signing output easier to verify.
1654 *) Fix the ASN1 encoding of tags using the 'long form'.
1657 *) New ASN1 functions, i2c_* and c2i_* for INTEGER and BIT
1658 STRING types. These convert content octets to and from the
1659 underlying type. The actual tag and length octets are
1660 already assumed to have been read in and checked. These
1661 are needed because all other string types have virtually
1662 identical handling apart from the tag. By having versions
1663 of the ASN1 functions that just operate on content octets
1664 IMPLICIT tagging can be handled properly. It also allows
1665 the ASN1_ENUMERATED code to be cut down because ASN1_ENUMERATED
1666 and ASN1_INTEGER are identical apart from the tag.
1669 *) Change the handling of OID objects as follows:
1671 - New object identifiers are inserted in objects.txt, following
1672 the syntax given in objects.README.
1673 - objects.pl is used to process obj_mac.num and create a new
1675 - obj_dat.pl is used to create a new obj_dat.h, using the data in
1678 This is currently kind of a hack, and the perl code in objects.pl
1679 isn't very elegant, but it works as I intended. The simplest way
1680 to check that it worked correctly is to look in obj_dat.h and
1681 check the array nid_objs and make sure the objects haven't moved
1682 around (this is important!). Additions are OK, as well as
1683 consistent name changes.
1686 *) Add BSD-style MD5-based passwords to 'openssl passwd' (option '-1').
1689 *) Addition of the command line parameter '-rand file' to 'openssl req'.
1690 The given file adds to whatever has already been seeded into the
1691 random pool through the RANDFILE configuration file option or
1692 environment variable, or the default random state file.
1695 *) mkstack.pl now sorts each macro group into lexical order.
1696 Previously the output order depended on the order the files
1697 appeared in the directory, resulting in needless rewriting
1701 *) Patches to make OpenSSL compile under Win32 again. Mostly
1702 work arounds for the VC++ problem that it treats func() as
1703 func(void). Also stripped out the parts of mkdef.pl that
1704 added extra typesafe functions: these no longer exist.
1707 *) Reorganisation of the stack code. The macros are now all
1708 collected in safestack.h . Each macro is defined in terms of
1709 a "stack macro" of the form SKM_<name>(type, a, b). The
1710 DEBUG_SAFESTACK is now handled in terms of function casts,
1711 this has the advantage of retaining type safety without the
1712 use of additional functions. If DEBUG_SAFESTACK is not defined
1713 then the non typesafe macros are used instead. Also modified the
1714 mkstack.pl script to handle the new form. Needs testing to see
1715 if which (if any) compilers it chokes and maybe make DEBUG_SAFESTACK
1716 the default if no major problems. Similar behaviour for ASN1_SET_OF
1717 and PKCS12_STACK_OF.
1720 *) When some versions of IIS use the 'NET' form of private key the
1721 key derivation algorithm is different. Normally MD5(password) is
1722 used as a 128 bit RC4 key. In the modified case
1723 MD5(MD5(password) + "SGCKEYSALT") is used insted. Added some
1724 new functions i2d_RSA_NET(), d2i_RSA_NET() etc which are the same
1725 as the old Netscape_RSA functions except they have an additional
1726 'sgckey' parameter which uses the modified algorithm. Also added
1727 an -sgckey command line option to the rsa utility. Thanks to
1728 Adrian Peck <bertie@ncipher.com> for posting details of the modified
1729 algorithm to openssl-dev.
1732 *) The evp_local.h macros were using 'c.##kname' which resulted in
1733 invalid expansion on some systems (SCO 5.0.5 for example).
1734 Corrected to 'c.kname'.
1735 [Phillip Porch <root@theporch.com>]
1737 *) New X509_get1_email() and X509_REQ_get1_email() functions that return
1738 a STACK of email addresses from a certificate or request, these look
1739 in the subject name and the subject alternative name extensions and
1740 omit any duplicate addresses.
1743 *) Re-implement BN_mod_exp2_mont using independent (and larger) windows.
1744 This makes DSA verification about 2 % faster.
1747 *) Increase maximum window size in BN_mod_exp_... to 6 bits instead of 5
1748 (meaning that now 2^5 values will be precomputed, which is only 4 KB
1749 plus overhead for 1024 bit moduli).
1750 This makes exponentiations about 0.5 % faster for 1024 bit
1751 exponents (as measured by "openssl speed rsa2048").
1754 *) Rename memory handling macros to avoid conflicts with other
1756 Malloc => OPENSSL_malloc
1757 Malloc_locked => OPENSSL_malloc_locked
1758 Realloc => OPENSSL_realloc
1759 Free => OPENSSL_free
1762 *) New function BN_mod_exp_mont_word for small bases (roughly 15%
1763 faster than BN_mod_exp_mont, i.e. 7% for a full DH exchange).
1766 *) CygWin32 support.
1767 [John Jarvie <jjarvie@newsguy.com>]
1769 *) The type-safe stack code has been rejigged. It is now only compiled
1770 in when OpenSSL is configured with the DEBUG_SAFESTACK option and
1771 by default all type-specific stack functions are "#define"d back to
1772 standard stack functions. This results in more streamlined output
1773 but retains the type-safety checking possibilities of the original
1777 *) The STACK code has been cleaned up, and certain type declarations
1778 that didn't make a lot of sense have been brought in line. This has
1779 also involved a cleanup of sorts in safestack.h to more correctly
1780 map type-safe stack functions onto their plain stack counterparts.
1781 This work has also resulted in a variety of "const"ifications of
1782 lots of the code, especially "_cmp" operations which should normally
1783 be prototyped with "const" parameters anyway.
1786 *) When generating bytes for the first time in md_rand.c, 'stir the pool'
1787 by seeding with STATE_SIZE dummy bytes (with zero entropy count).
1788 (The PRNG state consists of two parts, the large pool 'state' and 'md',
1789 where all of 'md' is used each time the PRNG is used, but 'state'
1790 is used only indexed by a cyclic counter. As entropy may not be
1791 well distributed from the beginning, 'md' is important as a
1792 chaining variable. However, the output function chains only half
1793 of 'md', i.e. 80 bits. ssleay_rand_add, on the other hand, chains
1794 all of 'md', and seeding with STATE_SIZE dummy bytes will result
1795 in all of 'state' being rewritten, with the new values depending
1796 on virtually all of 'md'. This overcomes the 80 bit limitation.)
1799 *) In ssl/s2_clnt.c and ssl/s3_clnt.c, call ERR_clear_error() when
1800 the handshake is continued after ssl_verify_cert_chain();
1801 otherwise, if SSL_VERIFY_NONE is set, remaining error codes
1802 can lead to 'unexplainable' connection aborts later.
1803 [Bodo Moeller; problem tracked down by Lutz Jaenicke]
1805 *) Major EVP API cipher revision.
1806 Add hooks for extra EVP features. This allows various cipher
1807 parameters to be set in the EVP interface. Support added for variable
1808 key length ciphers via the EVP_CIPHER_CTX_set_key_length() function and
1809 setting of RC2 and RC5 parameters.
1811 Modify EVP_OpenInit() and EVP_SealInit() to cope with variable key length
1814 Remove lots of duplicated code from the EVP library. For example *every*
1815 cipher init() function handles the 'iv' in the same way according to the
1816 cipher mode. They also all do nothing if the 'key' parameter is NULL and
1817 for CFB and OFB modes they zero ctx->num.
1819 New functionality allows removal of S/MIME code RC2 hack.
1821 Most of the routines have the same form and so can be declared in terms
1824 By shifting this to the top level EVP_CipherInit() it can be removed from
1825 all individual ciphers. If the cipher wants to handle IVs or keys
1826 differently it can set the EVP_CIPH_CUSTOM_IV or EVP_CIPH_ALWAYS_CALL_INIT
1829 Change lots of functions like EVP_EncryptUpdate() to now return a
1830 value: although software versions of the algorithms cannot fail
1831 any installed hardware versions can.
1834 *) Implement SSL_OP_TLS_ROLLBACK_BUG: In ssl3_get_client_key_exchange, if
1835 this option is set, tolerate broken clients that send the negotiated
1836 protocol version number instead of the requested protocol version
1840 *) Call dh_tmp_cb (set by ..._TMP_DH_CB) with correct 'is_export' flag;
1841 i.e. non-zero for export ciphersuites, zero otherwise.
1842 Previous versions had this flag inverted, inconsistent with
1843 rsa_tmp_cb (..._TMP_RSA_CB).
1844 [Bodo Moeller; problem reported by Amit Chopra]
1846 *) Add missing DSA library text string. Work around for some IIS
1847 key files with invalid SEQUENCE encoding.
1850 *) Add a document (doc/standards.txt) that list all kinds of standards
1851 and so on that are implemented in OpenSSL.
1854 *) Enhance c_rehash script. Old version would mishandle certificates
1855 with the same subject name hash and wouldn't handle CRLs at all.
1856 Added -fingerprint option to crl utility, to support new c_rehash
1860 *) Eliminate non-ANSI declarations in crypto.h and stack.h.
1863 *) Fix for SSL server purpose checking. Server checking was
1864 rejecting certificates which had extended key usage present
1865 but no ssl client purpose.
1866 [Steve Henson, reported by Rene Grosser <grosser@hisolutions.com>]
1868 *) Make PKCS#12 code work with no password. The PKCS#12 spec
1869 is a little unclear about how a blank password is handled.
1870 Since the password in encoded as a BMPString with terminating
1871 double NULL a zero length password would end up as just the
1872 double NULL. However no password at all is different and is
1873 handled differently in the PKCS#12 key generation code. NS
1874 treats a blank password as zero length. MSIE treats it as no
1875 password on export: but it will try both on import. We now do
1876 the same: PKCS12_parse() tries zero length and no password if
1877 the password is set to "" or NULL (NULL is now a valid password:
1878 it wasn't before) as does the pkcs12 application.
1881 *) Bugfixes in apps/x509.c: Avoid a memory leak; and don't use
1882 perror when PEM_read_bio_X509_REQ fails, the error message must
1883 be obtained from the error queue.
1886 *) Avoid 'thread_hash' memory leak in crypto/err/err.c by freeing
1887 it in ERR_remove_state if appropriate, and change ERR_get_state
1888 accordingly to avoid race conditions (this is necessary because
1889 thread_hash is no longer constant once set).
1892 *) Bugfix for linux-elf makefile.one.
1895 *) RSA_get_default_method() will now cause a default
1896 RSA_METHOD to be chosen if one doesn't exist already.
1897 Previously this was only set during a call to RSA_new()
1898 or RSA_new_method(NULL) meaning it was possible for
1899 RSA_get_default_method() to return NULL.
1902 *) Added native name translation to the existing DSO code
1903 that will convert (if the flag to do so is set) filenames
1904 that are sufficiently small and have no path information
1905 into a canonical native form. Eg. "blah" converted to
1906 "libblah.so" or "blah.dll" etc.
1909 *) New function ERR_error_string_n(e, buf, len) which is like
1910 ERR_error_string(e, buf), but writes at most 'len' bytes
1911 including the 0 terminator. For ERR_error_string_n, 'buf'
1913 [Damien Miller <djm@mindrot.org>, Bodo Moeller]
1915 *) CONF library reworked to become more general. A new CONF
1916 configuration file reader "class" is implemented as well as a
1917 new functions (NCONF_*, for "New CONF") to handle it. The now
1918 old CONF_* functions are still there, but are reimplemented to
1919 work in terms of the new functions. Also, a set of functions
1920 to handle the internal storage of the configuration data is
1921 provided to make it easier to write new configuration file
1922 reader "classes" (I can definitely see something reading a
1923 configuration file in XML format, for example), called _CONF_*,
1924 or "the configuration storage API"...
1926 The new configuration file reading functions are:
1928 NCONF_new, NCONF_free, NCONF_load, NCONF_load_fp, NCONF_load_bio,
1929 NCONF_get_section, NCONF_get_string, NCONF_get_numbre
1931 NCONF_default, NCONF_WIN32
1933 NCONF_dump_fp, NCONF_dump_bio
1935 NCONF_default and NCONF_WIN32 are method (or "class") choosers,
1936 NCONF_new creates a new CONF object. This works in the same way
1937 as other interfaces in OpenSSL, like the BIO interface.
1938 NCONF_dump_* dump the internal storage of the configuration file,
1939 which is useful for debugging. All other functions take the same
1940 arguments as the old CONF_* functions wth the exception of the
1941 first that must be a `CONF *' instead of a `LHASH *'.
1943 To make it easer to use the new classes with the old CONF_* functions,
1944 the function CONF_set_default_method is provided.
1947 *) Add '-tls1' option to 'openssl ciphers', which was already
1948 mentioned in the documentation but had not been implemented.
1949 (This option is not yet really useful because even the additional
1950 experimental TLS 1.0 ciphers are currently treated as SSL 3.0 ciphers.)
1953 *) Initial DSO code added into libcrypto for letting OpenSSL (and
1954 OpenSSL-based applications) load shared libraries and bind to
1955 them in a portable way.
1956 [Geoff Thorpe, with contributions from Richard Levitte]
1958 Changes between 0.9.5 and 0.9.5a [1 Apr 2000]
1960 *) Make sure _lrotl and _lrotr are only used with MSVC.
1962 *) Use lock CRYPTO_LOCK_RAND correctly in ssleay_rand_status
1963 (the default implementation of RAND_status).
1965 *) Rename openssl x509 option '-crlext', which was added in 0.9.5,
1966 to '-clrext' (= clear extensions), as intended and documented.
1967 [Bodo Moeller; inconsistency pointed out by Michael Attili
1970 *) Fix for HMAC. It wasn't zeroing the rest of the block if the key length
1971 was larger than the MD block size.
1972 [Steve Henson, pointed out by Yost William <YostW@tce.com>]
1974 *) Modernise PKCS12_parse() so it uses STACK_OF(X509) for its ca argument
1975 fix a leak when the ca argument was passed as NULL. Stop X509_PUBKEY_set()
1976 using the passed key: if the passed key was a private key the result
1977 of X509_print(), for example, would be to print out all the private key
1981 *) des_quad_cksum() byte order bug fix.
1982 [Ulf Möller, using the problem description in krb4-0.9.7, where
1983 the solution is attributed to Derrick J Brashear <shadow@DEMENTIA.ORG>]
1985 *) Fix so V_ASN1_APP_CHOOSE works again: however its use is strongly
1987 [Steve Henson, pointed out by Brian Korver <briank@cs.stanford.edu>]
1989 *) For easily testing in shell scripts whether some command
1990 'openssl XXX' exists, the new pseudo-command 'openssl no-XXX'
1991 returns with exit code 0 iff no command of the given name is available.
1992 'no-XXX' is printed in this case, 'XXX' otherwise. In both cases,
1993 the output goes to stdout and nothing is printed to stderr.
1994 Additional arguments are always ignored.
1996 Since for each cipher there is a command of the same name,
1997 the 'no-cipher' compilation switches can be tested this way.
1999 ('openssl no-XXX' is not able to detect pseudo-commands such
2000 as 'quit', 'list-XXX-commands', or 'no-XXX' itself.)
2003 *) Update test suite so that 'make test' succeeds in 'no-rsa' configuration.
2006 *) For SSL_[CTX_]set_tmp_dh, don't create a DH key if SSL_OP_SINGLE_DH_USE
2007 is set; it will be thrown away anyway because each handshake creates
2009 ssl_cert_dup, which is used by SSL_new, now copies DH keys in addition
2010 to parameters -- in previous versions (since OpenSSL 0.9.3) the
2011 'default key' from SSL_CTX_set_tmp_dh would always be lost, meanining
2012 you effectivly got SSL_OP_SINGLE_DH_USE when using this macro.
2015 *) New s_client option -ign_eof: EOF at stdin is ignored, and
2016 'Q' and 'R' lose their special meanings (quit/renegotiate).
2017 This is part of what -quiet does; unlike -quiet, -ign_eof
2018 does not suppress any output.
2021 *) Add compatibility options to the purpose and trust code. The
2022 purpose X509_PURPOSE_ANY is "any purpose" which automatically
2023 accepts a certificate or CA, this was the previous behaviour,
2024 with all the associated security issues.
2026 X509_TRUST_COMPAT is the old trust behaviour: only and
2027 automatically trust self signed roots in certificate store. A
2028 new trust setting X509_TRUST_DEFAULT is used to specify that
2029 a purpose has no associated trust setting and it should instead
2030 use the value in the default purpose.
2033 *) Fix the PKCS#8 DSA private key code so it decodes keys again
2034 and fix a memory leak.
2037 *) In util/mkerr.pl (which implements 'make errors'), preserve
2038 reason strings from the previous version of the .c file, as
2039 the default to have only downcase letters (and digits) in
2040 automatically generated reasons codes is not always appropriate.
2043 *) In ERR_load_ERR_strings(), build an ERR_LIB_SYS error reason table
2044 using strerror. Previously, ERR_reason_error_string() returned
2045 library names as reason strings for SYSerr; but SYSerr is a special
2046 case where small numbers are errno values, not library numbers.
2049 *) Add '-dsaparam' option to 'openssl dhparam' application. This
2050 converts DSA parameters into DH parameters. (When creating parameters,
2051 DSA_generate_parameters is used.)
2054 *) Include 'length' (recommended exponent length) in C code generated
2055 by 'openssl dhparam -C'.
2058 *) The second argument to set_label in perlasm was already being used
2059 so couldn't be used as a "file scope" flag. Moved to third argument
2063 *) In PEM_ASN1_write_bio and some other functions, use RAND_pseudo_bytes
2064 instead of RAND_bytes for encryption IVs and salts.
2067 *) Include RAND_status() into RAND_METHOD instead of implementing
2068 it only for md_rand.c Otherwise replacing the PRNG by calling
2069 RAND_set_rand_method would be impossible.
2072 *) Don't let DSA_generate_key() enter an infinite loop if the random
2073 number generation fails.
2076 *) New 'rand' application for creating pseudo-random output.
2079 *) Added configuration support for Linux/IA64
2080 [Rolf Haberrecker <rolf@suse.de>]
2082 *) Assembler module support for Mingw32.
2085 *) Shared library support for HPUX (in shlib/).
2086 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE> and Anonymous]
2088 *) Shared library support for Solaris gcc.
2089 [Lutz Behnke <behnke@trustcenter.de>]
2091 Changes between 0.9.4 and 0.9.5 [28 Feb 2000]
2093 *) PKCS7_encrypt() was adding text MIME headers twice because they
2094 were added manually and by SMIME_crlf_copy().
2097 *) In bntest.c don't call BN_rand with zero bits argument.
2098 [Steve Henson, pointed out by Andrew W. Gray <agray@iconsinc.com>]
2100 *) BN_mul bugfix: In bn_mul_part_recursion() only the a>a[n] && b>b[n]
2101 case was implemented. This caused BN_div_recp() to fail occasionally.
2104 *) Add an optional second argument to the set_label() in the perl
2105 assembly language builder. If this argument exists and is set
2106 to 1 it signals that the assembler should use a symbol whose
2107 scope is the entire file, not just the current function. This
2108 is needed with MASM which uses the format label:: for this scope.
2109 [Steve Henson, pointed out by Peter Runestig <peter@runestig.com>]
2111 *) Change the ASN1 types so they are typedefs by default. Before
2112 almost all types were #define'd to ASN1_STRING which was causing
2113 STACK_OF() problems: you couldn't declare STACK_OF(ASN1_UTF8STRING)
2117 *) Change names of new functions to the new get1/get0 naming
2118 convention: After 'get1', the caller owns a reference count
2119 and has to call ..._free; 'get0' returns a pointer to some
2120 data structure without incrementing reference counters.
2121 (Some of the existing 'get' functions increment a reference
2122 counter, some don't.)
2123 Similarly, 'set1' and 'add1' functions increase reference
2124 counters or duplicate objects.
2127 *) Allow for the possibility of temp RSA key generation failure:
2128 the code used to assume it always worked and crashed on failure.
2131 *) Fix potential buffer overrun problem in BIO_printf().
2132 [Ulf Möller, using public domain code by Patrick Powell; problem
2133 pointed out by David Sacerdote <das33@cornell.edu>]
2135 *) Support EGD <http://www.lothar.com/tech/crypto/>. New functions
2136 RAND_egd() and RAND_status(). In the command line application,
2137 the EGD socket can be specified like a seed file using RANDFILE
2141 *) Allow the string CERTIFICATE to be tolerated in PKCS#7 structures.
2142 Some CAs (e.g. Verisign) distribute certificates in this form.
2145 *) Remove the SSL_ALLOW_ADH compile option and set the default cipher
2146 list to exclude them. This means that no special compilation option
2147 is needed to use anonymous DH: it just needs to be included in the
2151 *) Change the EVP_MD_CTX_type macro so its meaning consistent with
2152 EVP_MD_type. The old functionality is available in a new macro called
2153 EVP_MD_md(). Change code that uses it and update docs.
2156 *) ..._ctrl functions now have corresponding ..._callback_ctrl functions
2157 where the 'void *' argument is replaced by a function pointer argument.
2158 Previously 'void *' was abused to point to functions, which works on
2159 many platforms, but is not correct. As these functions are usually
2160 called by macros defined in OpenSSL header files, most source code
2161 should work without changes.
2164 *) <openssl/opensslconf.h> (which is created by Configure) now contains
2165 sections with information on -D... compiler switches used for
2166 compiling the library so that applications can see them. To enable
2167 one of these sections, a pre-processor symbol OPENSSL_..._DEFINES
2168 must be defined. E.g.,
2169 #define OPENSSL_ALGORITHM_DEFINES
2170 #include <openssl/opensslconf.h>
2171 defines all pertinent NO_<algo> symbols, such as NO_IDEA, NO_RSA, etc.
2172 [Richard Levitte, Ulf and Bodo Möller]
2174 *) Bugfix: Tolerate fragmentation and interleaving in the SSL 3/TLS
2178 *) Change the 'other' type in certificate aux info to a STACK_OF
2179 X509_ALGOR. Although not an AlgorithmIdentifier as such it has
2180 the required ASN1 format: arbitrary types determined by an OID.
2183 *) Add some PEM_write_X509_REQ_NEW() functions and a command line
2184 argument to 'req'. This is not because the function is newer or
2185 better than others it just uses the work 'NEW' in the certificate
2186 request header lines. Some software needs this.
2189 *) Reorganise password command line arguments: now passwords can be
2190 obtained from various sources. Delete the PEM_cb function and make
2191 it the default behaviour: i.e. if the callback is NULL and the
2192 usrdata argument is not NULL interpret it as a null terminated pass
2193 phrase. If usrdata and the callback are NULL then the pass phrase
2194 is prompted for as usual.
2197 *) Add support for the Compaq Atalla crypto accelerator. If it is installed,
2198 the support is automatically enabled. The resulting binaries will
2199 autodetect the card and use it if present.
2200 [Ben Laurie and Compaq Inc.]
2202 *) Work around for Netscape hang bug. This sends certificate request
2203 and server done in one record. Since this is perfectly legal in the
2204 SSL/TLS protocol it isn't a "bug" option and is on by default. See
2205 the bugs/SSLv3 entry for more info.
2208 *) HP-UX tune-up: new unified configs, HP C compiler bug workaround.
2211 *) Add -rand argument to smime and pkcs12 applications and read/write
2215 *) New 'passwd' tool for crypt(3) and apr1 password hashes.
2218 *) Add command line password options to the remaining applications.
2221 *) Bug fix for BN_div_recp() for numerators with an even number of
2225 *) More tests in bntest.c, and changed test_bn output.
2228 *) ./config recognizes MacOS X now.
2231 *) Bug fix for BN_div() when the first words of num and divsor are
2232 equal (it gave wrong results if (rem=(n1-q*d0)&BN_MASK2) < d0).
2235 *) Add support for various broken PKCS#8 formats, and command line
2236 options to produce them.
2239 *) New functions BN_CTX_start(), BN_CTX_get() and BT_CTX_end() to
2240 get temporary BIGNUMs from a BN_CTX.
2243 *) Correct return values in BN_mod_exp_mont() and BN_mod_exp2_mont()
2247 *) Change the SSLeay_add_all_*() functions to OpenSSL_add_all_*() and
2248 include a #define from the old name to the new. The original intent
2249 was that statically linked binaries could for example just call
2250 SSLeay_add_all_ciphers() to just add ciphers to the table and not
2251 link with digests. This never worked becayse SSLeay_add_all_digests()
2252 and SSLeay_add_all_ciphers() were in the same source file so calling
2253 one would link with the other. They are now in separate source files.
2256 *) Add a new -notext option to 'ca' and a -pubkey option to 'spkac'.
2259 *) Use a less unusual form of the Miller-Rabin primality test (it used
2260 a binary algorithm for exponentiation integrated into the Miller-Rabin
2261 loop, our standard modexp algorithms are faster).
2264 *) Support for the EBCDIC character set completed.
2265 [Martin Kraemer <Martin.Kraemer@Mch.SNI.De>]
2267 *) Source code cleanups: use const where appropriate, eliminate casts,
2268 use void * instead of char * in lhash.
2271 *) Bugfix: ssl3_send_server_key_exchange was not restartable
2272 (the state was not changed to SSL3_ST_SW_KEY_EXCH_B, and because of
2273 this the server could overwrite ephemeral keys that the client
2277 *) Turn DSA_is_prime into a macro that calls BN_is_prime,
2278 using 50 iterations of the Rabin-Miller test.
2280 DSA_generate_parameters now uses BN_is_prime_fasttest (with 50
2281 iterations of the Rabin-Miller test as required by the appendix
2282 to FIPS PUB 186[-1]) instead of DSA_is_prime.
2283 As BN_is_prime_fasttest includes trial division, DSA parameter
2284 generation becomes much faster.
2286 This implies a change for the callback functions in DSA_is_prime
2287 and DSA_generate_parameters: The callback function is called once
2288 for each positive witness in the Rabin-Miller test, not just
2289 occasionally in the inner loop; and the parameters to the
2290 callback function now provide an iteration count for the outer
2291 loop rather than for the current invocation of the inner loop.
2292 DSA_generate_parameters additionally can call the callback
2293 function with an 'iteration count' of -1, meaning that a
2294 candidate has passed the trial division test (when q is generated
2295 from an application-provided seed, trial division is skipped).
2298 *) New function BN_is_prime_fasttest that optionally does trial
2299 division before starting the Rabin-Miller test and has
2300 an additional BN_CTX * argument (whereas BN_is_prime always
2301 has to allocate at least one BN_CTX).
2302 'callback(1, -1, cb_arg)' is called when a number has passed the
2303 trial division stage.
2306 *) Fix for bug in CRL encoding. The validity dates weren't being handled
2310 *) New -pkcs12 option to CA.pl script to write out a PKCS#12 file.
2313 *) New function BN_pseudo_rand().
2316 *) Clean up BN_mod_mul_montgomery(): replace the broken (and unreadable)
2317 bignum version of BN_from_montgomery() with the working code from
2318 SSLeay 0.9.0 (the word based version is faster anyway), and clean up
2322 *) Avoid a race condition in s2_clnt.c (function get_server_hello) that
2323 made it impossible to use the same SSL_SESSION data structure in
2324 SSL2 clients in multiple threads.
2327 *) The return value of RAND_load_file() no longer counts bytes obtained
2328 by stat(). RAND_load_file(..., -1) is new and uses the complete file
2329 to seed the PRNG (previously an explicit byte count was required).
2330 [Ulf Möller, Bodo Möller]
2332 *) Clean up CRYPTO_EX_DATA functions, some of these didn't have prototypes
2333 used (char *) instead of (void *) and had casts all over the place.
2336 *) Make BN_generate_prime() return NULL on error if ret!=NULL.
2339 *) Retain source code compatibility for BN_prime_checks macro:
2340 BN_is_prime(..., BN_prime_checks, ...) now uses
2341 BN_prime_checks_for_size to determine the appropriate number of
2342 Rabin-Miller iterations.
2345 *) Diffie-Hellman uses "safe" primes: DH_check() return code renamed to
2346 DH_CHECK_P_NOT_SAFE_PRIME.
2347 (Check if this is true? OpenPGP calls them "strong".)
2350 *) Merge the functionality of "dh" and "gendh" programs into a new program
2351 "dhparam". The old programs are retained for now but will handle DH keys
2352 (instead of parameters) in future.
2355 *) Make the ciphers, s_server and s_client programs check the return values
2356 when a new cipher list is set.
2359 *) Enhance the SSL/TLS cipher mechanism to correctly handle the TLS 56bit
2360 ciphers. Before when the 56bit ciphers were enabled the sorting was
2363 The syntax for the cipher sorting has been extended to support sorting by
2364 cipher-strength (using the strength_bits hard coded in the tables).
2365 The new command is "@STRENGTH" (see also doc/apps/ciphers.pod).
2367 Fix a bug in the cipher-command parser: when supplying a cipher command
2368 string with an "undefined" symbol (neither command nor alphanumeric
2369 [A-Za-z0-9], ssl_set_cipher_list used to hang in an endless loop. Now
2370 an error is flagged.
2372 Due to the strength-sorting extension, the code of the
2373 ssl_create_cipher_list() function was completely rearranged. I hope that
2374 the readability was also increased :-)
2375 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
2377 *) Minor change to 'x509' utility. The -CAcreateserial option now uses 1
2378 for the first serial number and places 2 in the serial number file. This
2379 avoids problems when the root CA is created with serial number zero and
2380 the first user certificate has the same issuer name and serial number
2384 *) Fixes to X509_ATTRIBUTE utilities, change the 'req' program so it uses
2385 the new code. Add documentation for this stuff.
2388 *) Changes to X509_ATTRIBUTE utilities. These have been renamed from
2389 X509_*() to X509at_*() on the grounds that they don't handle X509
2390 structures and behave in an analagous way to the X509v3 functions:
2391 they shouldn't be called directly but wrapper functions should be used
2394 So we also now have some wrapper functions that call the X509at functions
2395 when passed certificate requests. (TO DO: similar things can be done with
2396 PKCS#7 signed and unsigned attributes, PKCS#12 attributes and a few other
2397 things. Some of these need some d2i or i2d and print functionality
2398 because they handle more complex structures.)
2401 *) Add missing #ifndefs that caused missing symbols when building libssl
2402 as a shared library without RSA. Use #ifndef NO_SSL2 instead of
2403 NO_RSA in ssl/s2*.c.
2404 [Kris Kennaway <kris@hub.freebsd.org>, modified by Ulf Möller]
2406 *) Precautions against using the PRNG uninitialized: RAND_bytes() now
2407 has a return value which indicates the quality of the random data
2408 (1 = ok, 0 = not seeded). Also an error is recorded on the thread's
2409 error queue. New function RAND_pseudo_bytes() generates output that is
2410 guaranteed to be unique but not unpredictable. RAND_add is like
2411 RAND_seed, but takes an extra argument for an entropy estimate
2412 (RAND_seed always assumes full entropy).
2415 *) Do more iterations of Rabin-Miller probable prime test (specifically,
2416 3 for 1024-bit primes, 6 for 512-bit primes, 12 for 256-bit primes
2417 instead of only 2 for all lengths; see BN_prime_checks_for_size definition
2418 in crypto/bn/bn_prime.c for the complete table). This guarantees a
2419 false-positive rate of at most 2^-80 for random input.
2422 *) Rewrite ssl3_read_n (ssl/s3_pkt.c) avoiding a couple of bugs.
2425 *) New function X509_CTX_rget_chain() (renamed to X509_CTX_get1_chain
2426 in the 0.9.5 release), this returns the chain
2427 from an X509_CTX structure with a dup of the stack and all
2428 the X509 reference counts upped: so the stack will exist
2429 after X509_CTX_cleanup() has been called. Modify pkcs12.c
2432 Also make SSL_SESSION_print() print out the verify return
2436 *) Add manpage for the pkcs12 command. Also change the default
2437 behaviour so MAC iteration counts are used unless the new
2438 -nomaciter option is used. This improves file security and
2439 only older versions of MSIE (4.0 for example) need it.
2442 *) Honor the no-xxx Configure options when creating .DEF files.
2445 *) Add PKCS#10 attributes to field table: challengePassword,
2446 unstructuredName and unstructuredAddress. These are taken from
2447 draft PKCS#9 v2.0 but are compatible with v1.2 provided no
2448 international characters are used.
2450 More changes to X509_ATTRIBUTE code: allow the setting of types
2451 based on strings. Remove the 'loc' parameter when adding
2452 attributes because these will be a SET OF encoding which is sorted
2456 *) Initial changes to the 'req' utility to allow request generation
2457 automation. This will allow an application to just generate a template
2458 file containing all the field values and have req construct the
2461 Initial support for X509_ATTRIBUTE handling. Stacks of these are
2462 used all over the place including certificate requests and PKCS#7
2463 structures. They are currently handled manually where necessary with
2464 some primitive wrappers for PKCS#7. The new functions behave in a
2465 manner analogous to the X509 extension functions: they allow
2466 attributes to be looked up by NID and added.
2468 Later something similar to the X509V3 code would be desirable to
2469 automatically handle the encoding, decoding and printing of the
2470 more complex types. The string types like challengePassword can
2471 be handled by the string table functions.
2473 Also modified the multi byte string table handling. Now there is
2474 a 'global mask' which masks out certain types. The table itself
2475 can use the flag STABLE_NO_MASK to ignore the mask setting: this
2476 is useful when for example there is only one permissible type
2477 (as in countryName) and using the mask might result in no valid
2481 *) Clean up 'Finished' handling, and add functions SSL_get_finished and
2482 SSL_get_peer_finished to allow applications to obtain the latest
2483 Finished messages sent to the peer or expected from the peer,
2484 respectively. (SSL_get_peer_finished is usually the Finished message
2485 actually received from the peer, otherwise the protocol will be aborted.)
2487 As the Finished message are message digests of the complete handshake
2488 (with a total of 192 bits for TLS 1.0 and more for SSL 3.0), they can
2489 be used for external authentication procedures when the authentication
2490 provided by SSL/TLS is not desired or is not enough.
2493 *) Enhanced support for Alpha Linux is added. Now ./config checks if
2494 the host supports BWX extension and if Compaq C is present on the
2495 $PATH. Just exploiting of the BWX extension results in 20-30%
2496 performance kick for some algorithms, e.g. DES and RC4 to mention
2497 a couple. Compaq C in turn generates ~20% faster code for MD5 and
2501 *) Add support for MS "fast SGC". This is arguably a violation of the
2502 SSL3/TLS protocol. Netscape SGC does two handshakes: the first with
2503 weak crypto and after checking the certificate is SGC a second one
2504 with strong crypto. MS SGC stops the first handshake after receiving
2505 the server certificate message and sends a second client hello. Since
2506 a server will typically do all the time consuming operations before
2507 expecting any further messages from the client (server key exchange
2508 is the most expensive) there is little difference between the two.
2510 To get OpenSSL to support MS SGC we have to permit a second client
2511 hello message after we have sent server done. In addition we have to
2512 reset the MAC if we do get this second client hello.
2515 *) Add a function 'd2i_AutoPrivateKey()' this will automatically decide
2516 if a DER encoded private key is RSA or DSA traditional format. Changed
2517 d2i_PrivateKey_bio() to use it. This is only needed for the "traditional"
2518 format DER encoded private key. Newer code should use PKCS#8 format which
2519 has the key type encoded in the ASN1 structure. Added DER private key
2520 support to pkcs8 application.
2523 *) SSL 3/TLS 1 servers now don't request certificates when an anonymous
2524 ciphersuites has been selected (as required by the SSL 3/TLS 1
2525 specifications). Exception: When SSL_VERIFY_FAIL_IF_NO_PEER_CERT
2526 is set, we interpret this as a request to violate the specification
2527 (the worst that can happen is a handshake failure, and 'correct'
2528 behaviour would result in a handshake failure anyway).
2531 *) In SSL_CTX_add_session, take into account that there might be multiple
2532 SSL_SESSION structures with the same session ID (e.g. when two threads
2533 concurrently obtain them from an external cache).
2534 The internal cache can handle only one SSL_SESSION with a given ID,
2535 so if there's a conflict, we now throw out the old one to achieve
2539 *) Add OIDs for idea and blowfish in CBC mode. This will allow both
2540 to be used in PKCS#5 v2.0 and S/MIME. Also add checking to
2541 some routines that use cipher OIDs: some ciphers do not have OIDs
2542 defined and so they cannot be used for S/MIME and PKCS#5 v2.0 for
2546 *) Simplify the trust setting structure and code. Now we just have
2547 two sequences of OIDs for trusted and rejected settings. These will
2548 typically have values the same as the extended key usage extension
2549 and any application specific purposes.
2551 The trust checking code now has a default behaviour: it will just
2552 check for an object with the same NID as the passed id. Functions can
2553 be provided to override either the default behaviour or the behaviour
2554 for a given id. SSL client, server and email already have functions
2555 in place for compatibility: they check the NID and also return "trusted"
2556 if the certificate is self signed.
2559 *) Add d2i,i2d bio/fp functions for PrivateKey: these convert the
2560 traditional format into an EVP_PKEY structure.
2563 *) Add a password callback function PEM_cb() which either prompts for
2564 a password if usr_data is NULL or otherwise assumes it is a null
2565 terminated password. Allow passwords to be passed on command line
2566 environment or config files in a few more utilities.
2569 *) Add a bunch of DER and PEM functions to handle PKCS#8 format private
2570 keys. Add some short names for PKCS#8 PBE algorithms and allow them
2571 to be specified on the command line for the pkcs8 and pkcs12 utilities.
2572 Update documentation.
2575 *) Support for ASN1 "NULL" type. This could be handled before by using
2576 ASN1_TYPE but there wasn't any function that would try to read a NULL
2577 and produce an error if it couldn't. For compatibility we also have
2578 ASN1_NULL_new() and ASN1_NULL_free() functions but these are faked and
2579 don't allocate anything because they don't need to.
2582 *) Initial support for MacOS is now provided. Examine INSTALL.MacOS
2584 [Andy Polyakov, Roy Woods <roy@centicsystems.ca>]
2586 *) Rebuild of the memory allocation routines used by OpenSSL code and
2587 possibly others as well. The purpose is to make an interface that
2588 provide hooks so anyone can build a separate set of allocation and
2589 deallocation routines to be used by OpenSSL, for example memory
2590 pool implementations, or something else, which was previously hard
2591 since Malloc(), Realloc() and Free() were defined as macros having
2592 the values malloc, realloc and free, respectively (except for Win32
2593 compilations). The same is provided for memory debugging code.
2594 OpenSSL already comes with functionality to find memory leaks, but
2595 this gives people a chance to debug other memory problems.
2597 With these changes, a new set of functions and macros have appeared:
2599 CRYPTO_set_mem_debug_functions() [F]
2600 CRYPTO_get_mem_debug_functions() [F]
2601 CRYPTO_dbg_set_options() [F]
2602 CRYPTO_dbg_get_options() [F]
2603 CRYPTO_malloc_debug_init() [M]
2605 The memory debug functions are NULL by default, unless the library
2606 is compiled with CRYPTO_MDEBUG or friends is defined. If someone
2607 wants to debug memory anyway, CRYPTO_malloc_debug_init() (which
2608 gives the standard debugging functions that come with OpenSSL) or
2609 CRYPTO_set_mem_debug_functions() (tells OpenSSL to use functions
2610 provided by the library user) must be used. When the standard
2611 debugging functions are used, CRYPTO_dbg_set_options can be used to
2612 request additional information:
2613 CRYPTO_dbg_set_options(V_CYRPTO_MDEBUG_xxx) corresponds to setting
2614 the CRYPTO_MDEBUG_xxx macro when compiling the library.
2616 Also, things like CRYPTO_set_mem_functions will always give the
2617 expected result (the new set of functions is used for allocation
2618 and deallocation) at all times, regardless of platform and compiler
2621 To finish it up, some functions that were never use in any other
2622 way than through macros have a new API and new semantic:
2625 CRYPTO_dbg_realloc()
2628 All macros of value have retained their old syntax.
2629 [Richard Levitte and Bodo Moeller]
2631 *) Some S/MIME fixes. The OID for SMIMECapabilities was wrong, the
2632 ordering of SMIMECapabilities wasn't in "strength order" and there
2633 was a missing NULL in the AlgorithmIdentifier for the SHA1 signature
2637 *) Some ASN1 types with illegal zero length encoding (INTEGER,
2638 ENUMERATED and OBJECT IDENTIFIER) choked the ASN1 routines.
2639 [Frans Heymans <fheymans@isaserver.be>, modified by Steve Henson]
2641 *) Merge in my S/MIME library for OpenSSL. This provides a simple
2642 S/MIME API on top of the PKCS#7 code, a MIME parser (with enough
2643 functionality to handle multipart/signed properly) and a utility
2644 called 'smime' to call all this stuff. This is based on code I
2645 originally wrote for Celo who have kindly allowed it to be
2646 included in OpenSSL.
2649 *) Add variants des_set_key_checked and des_set_key_unchecked of
2650 des_set_key (aka des_key_sched). Global variable des_check_key
2651 decides which of these is called by des_set_key; this way
2652 des_check_key behaves as it always did, but applications and
2653 the library itself, which was buggy for des_check_key == 1,
2654 have a cleaner way to pick the version they need.
2657 *) New function PKCS12_newpass() which changes the password of a
2661 *) Modify X509_TRUST and X509_PURPOSE so it also uses a static and
2662 dynamic mix. In both cases the ids can be used as an index into the
2663 table. Also modified the X509_TRUST_add() and X509_PURPOSE_add()
2664 functions so they accept a list of the field values and the
2665 application doesn't need to directly manipulate the X509_TRUST
2669 *) Modify the ASN1_STRING_TABLE stuff so it also uses bsearch and doesn't
2673 *) Modify the way the V3 extension code looks up extensions. This now
2674 works in a similar way to the object code: we have some "standard"
2675 extensions in a static table which is searched with OBJ_bsearch()
2676 and the application can add dynamic ones if needed. The file
2677 crypto/x509v3/ext_dat.h now has the info: this file needs to be
2678 updated whenever a new extension is added to the core code and kept
2679 in ext_nid order. There is a simple program 'tabtest.c' which checks
2680 this. New extensions are not added too often so this file can readily
2681 be maintained manually.
2683 There are two big advantages in doing things this way. The extensions
2684 can be looked up immediately and no longer need to be "added" using
2685 X509V3_add_standard_extensions(): this function now does nothing.
2686 [Side note: I get *lots* of email saying the extension code doesn't
2687 work because people forget to call this function]
2688 Also no dynamic allocation is done unless new extensions are added:
2689 so if we don't add custom extensions there is no need to call
2690 X509V3_EXT_cleanup().
2693 *) Modify enc utility's salting as follows: make salting the default. Add a
2694 magic header, so unsalted files fail gracefully instead of just decrypting
2695 to garbage. This is because not salting is a big security hole, so people
2696 should be discouraged from doing it.
2699 *) Fixes and enhancements to the 'x509' utility. It allowed a message
2700 digest to be passed on the command line but it only used this
2701 parameter when signing a certificate. Modified so all relevant
2702 operations are affected by the digest parameter including the
2703 -fingerprint and -x509toreq options. Also -x509toreq choked if a
2704 DSA key was used because it didn't fix the digest.
2707 *) Initial certificate chain verify code. Currently tests the untrusted
2708 certificates for consistency with the verify purpose (which is set
2709 when the X509_STORE_CTX structure is set up) and checks the pathlength.
2711 There is a NO_CHAIN_VERIFY compilation option to keep the old behaviour:
2712 this is because it will reject chains with invalid extensions whereas
2713 every previous version of OpenSSL and SSLeay made no checks at all.
2715 Trust code: checks the root CA for the relevant trust settings. Trust
2716 settings have an initial value consistent with the verify purpose: e.g.
2717 if the verify purpose is for SSL client use it expects the CA to be
2718 trusted for SSL client use. However the default value can be changed to
2719 permit custom trust settings: one example of this would be to only trust
2720 certificates from a specific "secure" set of CAs.
2722 Also added X509_STORE_CTX_new() and X509_STORE_CTX_free() functions
2723 which should be used for version portability: especially since the
2724 verify structure is likely to change more often now.
2726 SSL integration. Add purpose and trust to SSL_CTX and SSL and functions
2727 to set them. If not set then assume SSL clients will verify SSL servers
2730 Two new options to the verify program: -untrusted allows a set of
2731 untrusted certificates to be passed in and -purpose which sets the
2732 intended purpose of the certificate. If a purpose is set then the
2733 new chain verify code is used to check extension consistency.
2736 *) Support for the authority information access extension.
2739 *) Modify RSA and DSA PEM read routines to transparently handle
2740 PKCS#8 format private keys. New *_PUBKEY_* functions that handle
2741 public keys in a format compatible with certificate
2742 SubjectPublicKeyInfo structures. Unfortunately there were already
2743 functions called *_PublicKey_* which used various odd formats so
2744 these are retained for compatibility: however the DSA variants were
2745 never in a public release so they have been deleted. Changed dsa/rsa
2746 utilities to handle the new format: note no releases ever handled public
2747 keys so we should be OK.
2749 The primary motivation for this change is to avoid the same fiasco
2750 that dogs private keys: there are several incompatible private key
2751 formats some of which are standard and some OpenSSL specific and
2752 require various evil hacks to allow partial transparent handling and
2753 even then it doesn't work with DER formats. Given the option anything
2754 other than PKCS#8 should be dumped: but the other formats have to
2755 stay in the name of compatibility.
2757 With public keys and the benefit of hindsight one standard format
2758 is used which works with EVP_PKEY, RSA or DSA structures: though
2759 it clearly returns an error if you try to read the wrong kind of key.
2761 Added a -pubkey option to the 'x509' utility to output the public key.
2762 Also rename the EVP_PKEY_get_*() to EVP_PKEY_rget_*()
2763 (renamed to EVP_PKEY_get1_*() in the OpenSSL 0.9.5 release) and add
2764 EVP_PKEY_rset_*() functions (renamed to EVP_PKEY_set1_*())
2765 that do the same as the EVP_PKEY_assign_*() except they up the
2766 reference count of the added key (they don't "swallow" the
2770 *) Fixes to crypto/x509/by_file.c the code to read in certificates and
2771 CRLs would fail if the file contained no certificates or no CRLs:
2772 added a new function to read in both types and return the number
2773 read: this means that if none are read it will be an error. The
2774 DER versions of the certificate and CRL reader would always fail
2775 because it isn't possible to mix certificates and CRLs in DER format
2776 without choking one or the other routine. Changed this to just read
2777 a certificate: this is the best we can do. Also modified the code
2778 in apps/verify.c to take notice of return codes: it was previously
2779 attempting to read in certificates from NULL pointers and ignoring
2780 any errors: this is one reason why the cert and CRL reader seemed
2781 to work. It doesn't check return codes from the default certificate
2782 routines: these may well fail if the certificates aren't installed.
2785 *) Code to support otherName option in GeneralName.
2788 *) First update to verify code. Change the verify utility
2789 so it warns if it is passed a self signed certificate:
2790 for consistency with the normal behaviour. X509_verify
2791 has been modified to it will now verify a self signed
2792 certificate if *exactly* the same certificate appears
2793 in the store: it was previously impossible to trust a
2794 single self signed certificate. This means that:
2795 openssl verify ss.pem
2796 now gives a warning about a self signed certificate but
2797 openssl verify -CAfile ss.pem ss.pem
2801 *) For servers, store verify_result in SSL_SESSION data structure
2802 (and add it to external session representation).
2803 This is needed when client certificate verifications fails,
2804 but an application-provided verification callback (set by
2805 SSL_CTX_set_cert_verify_callback) allows accepting the session
2806 anyway (i.e. leaves x509_store_ctx->error != X509_V_OK
2807 but returns 1): When the session is reused, we have to set
2808 ssl->verify_result to the appropriate error code to avoid
2810 [Bodo Moeller, problem pointed out by Lutz Jaenicke]
2812 *) Fix a bug in the new PKCS#7 code: it didn't consider the
2813 case in PKCS7_dataInit() where the signed PKCS7 structure
2814 didn't contain any existing data because it was being created.
2815 [Po-Cheng Chen <pocheng@nst.com.tw>, slightly modified by Steve Henson]
2817 *) Add a salt to the key derivation routines in enc.c. This
2818 forms the first 8 bytes of the encrypted file. Also add a
2819 -S option to allow a salt to be input on the command line.
2822 *) New function X509_cmp(). Oddly enough there wasn't a function
2823 to compare two certificates. We do this by working out the SHA1
2824 hash and comparing that. X509_cmp() will be needed by the trust
2828 *) SSL_get1_session() is like SSL_get_session(), but increments
2829 the reference count in the SSL_SESSION returned.
2830 [Geoff Thorpe <geoff@eu.c2.net>]
2832 *) Fix for 'req': it was adding a null to request attributes.
2833 Also change the X509_LOOKUP and X509_INFO code to handle
2834 certificate auxiliary information.
2837 *) Add support for 40 and 64 bit RC2 and RC4 algorithms: document
2841 *) Add the possibility to add extra information to the memory leak
2842 detecting output, to form tracebacks, showing from where each
2843 allocation was originated: CRYPTO_push_info("constant string") adds
2844 the string plus current file name and line number to a per-thread
2845 stack, CRYPTO_pop_info() does the obvious, CRYPTO_remove_all_info()
2846 is like calling CYRPTO_pop_info() until the stack is empty.
2847 Also updated memory leak detection code to be multi-thread-safe.
2850 *) Add options -text and -noout to pkcs7 utility and delete the
2851 encryption options which never did anything. Update docs.
2854 *) Add options to some of the utilities to allow the pass phrase
2855 to be included on either the command line (not recommended on
2856 OSes like Unix) or read from the environment. Update the
2857 manpages and fix a few bugs.
2860 *) Add a few manpages for some of the openssl commands.
2863 *) Fix the -revoke option in ca. It was freeing up memory twice,
2864 leaking and not finding already revoked certificates.
2867 *) Extensive changes to support certificate auxiliary information.
2868 This involves the use of X509_CERT_AUX structure and X509_AUX
2869 functions. An X509_AUX function such as PEM_read_X509_AUX()
2870 can still read in a certificate file in the usual way but it
2871 will also read in any additional "auxiliary information". By
2872 doing things this way a fair degree of compatibility can be
2873 retained: existing certificates can have this information added
2874 using the new 'x509' options.
2876 Current auxiliary information includes an "alias" and some trust
2877 settings. The trust settings will ultimately be used in enhanced
2878 certificate chain verification routines: currently a certificate
2879 can only be trusted if it is self signed and then it is trusted
2883 *) Fix assembler for Alpha (tested only on DEC OSF not Linux or *BSD).
2884 The problem was that one of the replacement routines had not been working
2885 since SSLeay releases. For now the offending routine has been replaced
2886 with non-optimised assembler. Even so, this now gives around 95%
2887 performance improvement for 1024 bit RSA signs.
2890 *) Hack to fix PKCS#7 decryption when used with some unorthodox RC2
2891 handling. Most clients have the effective key size in bits equal to
2892 the key length in bits: so a 40 bit RC2 key uses a 40 bit (5 byte) key.
2893 A few however don't do this and instead use the size of the decrypted key
2894 to determine the RC2 key length and the AlgorithmIdentifier to determine
2895 the effective key length. In this case the effective key length can still
2896 be 40 bits but the key length can be 168 bits for example. This is fixed
2897 by manually forcing an RC2 key into the EVP_PKEY structure because the
2898 EVP code can't currently handle unusual RC2 key sizes: it always assumes
2899 the key length and effective key length are equal.
2902 *) Add a bunch of functions that should simplify the creation of
2903 X509_NAME structures. Now you should be able to do:
2904 X509_NAME_add_entry_by_txt(nm, "CN", MBSTRING_ASC, "Steve", -1, -1, 0);
2905 and have it automatically work out the correct field type and fill in
2906 the structures. The more adventurous can try:
2907 X509_NAME_add_entry_by_txt(nm, field, MBSTRING_UTF8, str, -1, -1, 0);
2908 and it will (hopefully) work out the correct multibyte encoding.
2911 *) Change the 'req' utility to use the new field handling and multibyte
2912 copy routines. Before the DN field creation was handled in an ad hoc
2913 way in req, ca, and x509 which was rather broken and didn't support
2914 BMPStrings or UTF8Strings. Since some software doesn't implement
2915 BMPStrings or UTF8Strings yet, they can be enabled using the config file
2916 using the dirstring_type option. See the new comment in the default
2917 openssl.cnf for more info.
2920 *) Make crypto/rand/md_rand.c more robust:
2921 - Assure unique random numbers after fork().
2922 - Make sure that concurrent threads access the global counter and
2923 md serializably so that we never lose entropy in them
2924 or use exactly the same state in multiple threads.
2925 Access to the large state is not always serializable because
2926 the additional locking could be a performance killer, and
2927 md should be large enough anyway.
2930 *) New file apps/app_rand.c with commonly needed functionality
2931 for handling the random seed file.
2933 Use the random seed file in some applications that previously did not:
2935 dsaparam -genkey (which also ignored its '-rand' option),
2938 x509 (when signing).
2939 Except on systems with /dev/urandom, it is crucial to have a random
2940 seed file at least for key creation, DSA signing, and for DH exchanges;
2941 for RSA signatures we could do without one.
2943 gendh and gendsa (unlike genrsa) used to read only the first byte
2944 of each file listed in the '-rand' option. The function as previously
2945 found in genrsa is now in app_rand.c and is used by all programs
2946 that support '-rand'.
2949 *) In RAND_write_file, use mode 0600 for creating files;
2950 don't just chmod when it may be too late.
2953 *) Report an error from X509_STORE_load_locations
2954 when X509_LOOKUP_load_file or X509_LOOKUP_add_dir failed.
2957 *) New function ASN1_mbstring_copy() this copies a string in either
2958 ASCII, Unicode, Universal (4 bytes per character) or UTF8 format
2959 into an ASN1_STRING type. A mask of permissible types is passed
2960 and it chooses the "minimal" type to use or an error if not type
2964 *) Add function equivalents to the various macros in asn1.h. The old
2965 macros are retained with an M_ prefix. Code inside the library can
2966 use the M_ macros. External code (including the openssl utility)
2967 should *NOT* in order to be "shared library friendly".
2970 *) Add various functions that can check a certificate's extensions
2971 to see if it usable for various purposes such as SSL client,
2972 server or S/MIME and CAs of these types. This is currently
2973 VERY EXPERIMENTAL but will ultimately be used for certificate chain
2974 verification. Also added a -purpose flag to x509 utility to
2975 print out all the purposes.
2978 *) Add a CRYPTO_EX_DATA to X509 certificate structure and associated
2982 *) New X509V3_{X509,CRL,REVOKED}_get_d2i() functions. These will search
2983 for, obtain and decode and extension and obtain its critical flag.
2984 This allows all the necessary extension code to be handled in a
2985 single function call.
2988 *) RC4 tune-up featuring 30-40% performance improvement on most RISC
2989 platforms. See crypto/rc4/rc4_enc.c for further details.
2992 *) New -noout option to asn1parse. This causes no output to be produced
2993 its main use is when combined with -strparse and -out to extract data
2994 from a file (which may not be in ASN.1 format).
2997 *) Fix for pkcs12 program. It was hashing an invalid certificate pointer
2998 when producing the local key id.
2999 [Richard Levitte <levitte@stacken.kth.se>]
3001 *) New option -dhparam in s_server. This allows a DH parameter file to be
3002 stated explicitly. If it is not stated then it tries the first server
3003 certificate file. The previous behaviour hard coded the filename
3007 *) Add -pubin and -pubout options to the rsa and dsa commands. These allow
3008 a public key to be input or output. For example:
3009 openssl rsa -in key.pem -pubout -out pubkey.pem
3010 Also added necessary DSA public key functions to handle this.
3013 *) Fix so PKCS7_dataVerify() doesn't crash if no certificates are contained
3014 in the message. This was handled by allowing
3015 X509_find_by_issuer_and_serial() to tolerate a NULL passed to it.
3016 [Steve Henson, reported by Sampo Kellomaki <sampo@mail.neuronio.pt>]
3018 *) Fix for bug in d2i_ASN1_bytes(): other ASN1 functions add an extra null
3019 to the end of the strings whereas this didn't. This would cause problems
3020 if strings read with d2i_ASN1_bytes() were later modified.
3021 [Steve Henson, reported by Arne Ansper <arne@ats.cyber.ee>]
3023 *) Fix for base64 decode bug. When a base64 bio reads only one line of
3024 data and it contains EOF it will end up returning an error. This is
3025 caused by input 46 bytes long. The cause is due to the way base64
3026 BIOs find the start of base64 encoded data. They do this by trying a
3027 trial decode on each line until they find one that works. When they
3028 do a flag is set and it starts again knowing it can pass all the
3029 data directly through the decoder. Unfortunately it doesn't reset
3030 the context it uses. This means that if EOF is reached an attempt
3031 is made to pass two EOFs through the context and this causes the
3032 resulting error. This can also cause other problems as well. As is
3033 usual with these problems it takes *ages* to find and the fix is
3034 trivial: move one line.
3035 [Steve Henson, reported by ian@uns.ns.ac.yu (Ivan Nejgebauer) ]
3037 *) Ugly workaround to get s_client and s_server working under Windows. The
3038 old code wouldn't work because it needed to select() on sockets and the
3039 tty (for keypresses and to see if data could be written). Win32 only
3040 supports select() on sockets so we select() with a 1s timeout on the
3041 sockets and then see if any characters are waiting to be read, if none
3042 are present then we retry, we also assume we can always write data to
3043 the tty. This isn't nice because the code then blocks until we've
3044 received a complete line of data and it is effectively polling the
3045 keyboard at 1s intervals: however it's quite a bit better than not
3046 working at all :-) A dedicated Windows application might handle this
3047 with an event loop for example.
3050 *) Enhance RSA_METHOD structure. Now there are two extra methods, rsa_sign
3051 and rsa_verify. When the RSA_FLAGS_SIGN_VER option is set these functions
3052 will be called when RSA_sign() and RSA_verify() are used. This is useful
3053 if rsa_pub_dec() and rsa_priv_enc() equivalents are not available.
3054 For this to work properly RSA_public_decrypt() and RSA_private_encrypt()
3055 should *not* be used: RSA_sign() and RSA_verify() must be used instead.
3056 This necessitated the support of an extra signature type NID_md5_sha1
3057 for SSL signatures and modifications to the SSL library to use it instead
3058 of calling RSA_public_decrypt() and RSA_private_encrypt().
3061 *) Add new -verify -CAfile and -CApath options to the crl program, these
3062 will lookup a CRL issuers certificate and verify the signature in a
3063 similar way to the verify program. Tidy up the crl program so it
3064 no longer accesses structures directly. Make the ASN1 CRL parsing a bit
3065 less strict. It will now permit CRL extensions even if it is not
3066 a V2 CRL: this will allow it to tolerate some broken CRLs.
3069 *) Initialize all non-automatic variables each time one of the openssl
3070 sub-programs is started (this is necessary as they may be started
3071 multiple times from the "OpenSSL>" prompt).
3072 [Lennart Bang, Bodo Moeller]
3074 *) Preliminary compilation option RSA_NULL which disables RSA crypto without
3075 removing all other RSA functionality (this is what NO_RSA does). This
3076 is so (for example) those in the US can disable those operations covered
3077 by the RSA patent while allowing storage and parsing of RSA keys and RSA
3081 *) Non-copying interface to BIO pairs.
3082 (still largely untested)
3085 *) New function ANS1_tag2str() to convert an ASN1 tag to a descriptive
3086 ASCII string. This was handled independently in various places before.
3089 *) New functions UTF8_getc() and UTF8_putc() that parse and generate
3090 UTF8 strings a character at a time.
3093 *) Use client_version from client hello to select the protocol
3094 (s23_srvr.c) and for RSA client key exchange verification
3095 (s3_srvr.c), as required by the SSL 3.0/TLS 1.0 specifications.
3098 *) Add various utility functions to handle SPKACs, these were previously
3099 handled by poking round in the structure internals. Added new function
3100 NETSCAPE_SPKI_print() to print out SPKAC and a new utility 'spkac' to
3101 print, verify and generate SPKACs. Based on an original idea from
3102 Massimiliano Pala <madwolf@comune.modena.it> but extensively modified.
3105 *) RIPEMD160 is operational on all platforms and is back in 'make test'.
3108 *) Allow the config file extension section to be overwritten on the
3109 command line. Based on an original idea from Massimiliano Pala
3110 <madwolf@comune.modena.it>. The new option is called -extensions
3111 and can be applied to ca, req and x509. Also -reqexts to override
3112 the request extensions in req and -crlexts to override the crl extensions
3116 *) Add new feature to the SPKAC handling in ca. Now you can include
3117 the same field multiple times by preceding it by "XXXX." for example:
3120 this is the same syntax as used in the req config file.
3123 *) Allow certificate extensions to be added to certificate requests. These
3124 are specified in a 'req_extensions' option of the req section of the
3125 config file. They can be printed out with the -text option to req but
3126 are otherwise ignored at present.
3129 *) Fix a horrible bug in enc_read() in crypto/evp/bio_enc.c: if the first
3130 data read consists of only the final block it would not decrypted because
3131 EVP_CipherUpdate() would correctly report zero bytes had been decrypted.
3132 A misplaced 'break' also meant the decrypted final block might not be
3133 copied until the next read.
3136 *) Initial support for DH_METHOD. Again based on RSA_METHOD. Also added
3137 a few extra parameters to the DH structure: these will be useful if
3138 for example we want the value of 'q' or implement X9.42 DH.
3141 *) Initial support for DSA_METHOD. This is based on the RSA_METHOD and
3142 provides hooks that allow the default DSA functions or functions on a
3143 "per key" basis to be replaced. This allows hardware acceleration and
3144 hardware key storage to be handled without major modification to the
3145 library. Also added low level modexp hooks and CRYPTO_EX structure and
3146 associated functions.
3149 *) Add a new flag to memory BIOs, BIO_FLAG_MEM_RDONLY. This marks the BIO
3150 as "read only": it can't be written to and the buffer it points to will
3151 not be freed. Reading from a read only BIO is much more efficient than
3152 a normal memory BIO. This was added because there are several times when
3153 an area of memory needs to be read from a BIO. The previous method was
3154 to create a memory BIO and write the data to it, this results in two
3155 copies of the data and an O(n^2) reading algorithm. There is a new
3156 function BIO_new_mem_buf() which creates a read only memory BIO from
3157 an area of memory. Also modified the PKCS#7 routines to use read only
3161 *) Bugfix: ssl23_get_client_hello did not work properly when called in
3162 state SSL23_ST_SR_CLNT_HELLO_B, i.e. when the first 7 bytes of
3163 a SSLv2-compatible client hello for SSLv3 or TLSv1 could be read,
3164 but a retry condition occured while trying to read the rest.
3167 *) The PKCS7_ENC_CONTENT_new() function was setting the content type as
3168 NID_pkcs7_encrypted by default: this was wrong since this should almost
3169 always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle
3170 the encrypted data type: this is a more sensible place to put it and it
3171 allows the PKCS#12 code to be tidied up that duplicated this
3175 *) Changed obj_dat.pl script so it takes its input and output files on
3176 the command line. This should avoid shell escape redirection problems
3180 *) Initial support for certificate extension requests, these are included
3181 in things like Xenroll certificate requests. Included functions to allow
3182 extensions to be obtained and added.
3185 *) -crlf option to s_client and s_server for sending newlines as
3186 CRLF (as required by many protocols).
3189 Changes between 0.9.3a and 0.9.4 [09 Aug 1999]
3191 *) Install libRSAglue.a when OpenSSL is built with RSAref.
3192 [Ralf S. Engelschall]
3194 *) A few more ``#ifndef NO_FP_API / #endif'' pairs for consistency.
3195 [Andrija Antonijevic <TheAntony2@bigfoot.com>]
3197 *) Fix -startdate and -enddate (which was missing) arguments to 'ca'
3201 *) New function DSA_dup_DH, which duplicates DSA parameters/keys as
3202 DH parameters/keys (q is lost during that conversion, but the resulting
3203 DH parameters contain its length).
3205 For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is
3206 much faster than DH_generate_parameters (which creates parameters
3207 where p = 2*q + 1), and also the smaller q makes DH computations
3208 much more efficient (160-bit exponentiation instead of 1024-bit
3209 exponentiation); so this provides a convenient way to support DHE
3210 ciphersuites in SSL/TLS servers (see ssl/ssltest.c). It is of
3211 utter importance to use
3212 SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
3214 SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
3215 when such DH parameters are used, because otherwise small subgroup
3216 attacks may become possible!
3219 *) Avoid memory leak in i2d_DHparams.
3222 *) Allow the -k option to be used more than once in the enc program:
3223 this allows the same encrypted message to be read by multiple recipients.
3226 *) New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts
3227 an ASN1_OBJECT to a text string. If the "no_name" parameter is set then
3228 it will always use the numerical form of the OID, even if it has a short
3232 *) Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp
3233 method only got called if p,q,dmp1,dmq1,iqmp components were present,
3234 otherwise bn_mod_exp was called. In the case of hardware keys for example
3235 no private key components need be present and it might store extra data
3236 in the RSA structure, which cannot be accessed from bn_mod_exp.
3237 By setting RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for
3238 private key operations.
3241 *) Added support for SPARC Linux.
3244 *) pem_password_cb function type incompatibly changed from
3245 typedef int pem_password_cb(char *buf, int size, int rwflag);
3247 ....(char *buf, int size, int rwflag, void *userdata);
3248 so that applications can pass data to their callbacks:
3249 The PEM[_ASN1]_{read,write}... functions and macros now take an
3250 additional void * argument, which is just handed through whenever
3251 the password callback is called.
3252 [Damien Miller <dmiller@ilogic.com.au>; tiny changes by Bodo Moeller]
3254 New function SSL_CTX_set_default_passwd_cb_userdata.
3256 Compatibility note: As many C implementations push function arguments
3257 onto the stack in reverse order, the new library version is likely to
3258 interoperate with programs that have been compiled with the old
3259 pem_password_cb definition (PEM_whatever takes some data that
3260 happens to be on the stack as its last argument, and the callback
3261 just ignores this garbage); but there is no guarantee whatsoever that
3264 *) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=...
3265 (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused
3266 problems not only on Windows, but also on some Unix platforms.
3267 To avoid problematic command lines, these definitions are now in an
3268 auto-generated file crypto/buildinf.h (created by crypto/Makefile.ssl
3269 for standard "make" builds, by util/mk1mf.pl for "mk1mf" builds).
3272 *) MIPS III/IV assembler module is reimplemented.
3275 *) More DES library cleanups: remove references to srand/rand and
3276 delete an unused file.
3279 *) Add support for the the free Netwide assembler (NASM) under Win32,
3280 since not many people have MASM (ml) and it can be hard to obtain.
3281 This is currently experimental but it seems to work OK and pass all
3282 the tests. Check out INSTALL.W32 for info.
3285 *) Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections
3286 without temporary keys kept an extra copy of the server key,
3287 and connections with temporary keys did not free everything in case
3291 *) New function RSA_check_key and new openssl rsa option -check
3292 for verifying the consistency of RSA keys.
3293 [Ulf Moeller, Bodo Moeller]
3295 *) Various changes to make Win32 compile work:
3296 1. Casts to avoid "loss of data" warnings in p5_crpt2.c
3297 2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned
3298 comparison" warnings.
3299 3. Add sk_<TYPE>_sort to DEF file generator and do make update.
3302 *) Add a debugging option to PKCS#5 v2 key generation function: when
3303 you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and
3304 derived keys are printed to stderr.
3307 *) Copy the flags in ASN1_STRING_dup().
3308 [Roman E. Pavlov <pre@mo.msk.ru>]
3310 *) The x509 application mishandled signing requests containing DSA
3311 keys when the signing key was also DSA and the parameters didn't match.
3313 It was supposed to omit the parameters when they matched the signing key:
3314 the verifying software was then supposed to automatically use the CA's
3315 parameters if they were absent from the end user certificate.
3317 Omitting parameters is no longer recommended. The test was also
3318 the wrong way round! This was probably due to unusual behaviour in
3319 EVP_cmp_parameters() which returns 1 if the parameters match.
3320 This meant that parameters were omitted when they *didn't* match and
3321 the certificate was useless. Certificates signed with 'ca' didn't have
3323 [Steve Henson, reported by Doug Erickson <Doug.Erickson@Part.NET>]
3325 *) Memory leak checking (-DCRYPTO_MDEBUG) had some problems.
3326 The interface is as follows:
3327 Applications can use
3328 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(),
3329 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop();
3330 "off" is now the default.
3331 The library internally uses
3332 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(),
3333 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on()
3334 to disable memory-checking temporarily.
3336 Some inconsistent states that previously were possible (and were
3337 even the default) are now avoided.
3339 -DCRYPTO_MDEBUG_TIME is new and additionally stores the current time
3340 with each memory chunk allocated; this is occasionally more helpful
3341 than just having a counter.
3343 -DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID.
3345 -DCRYPTO_MDEBUG_ALL enables all of the above, plus any future
3349 *) Introduce "mode" for SSL structures (with defaults in SSL_CTX),
3350 which largely parallels "options", but is for changing API behaviour,
3351 whereas "options" are about protocol behaviour.
3352 Initial "mode" flags are:
3354 SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when
3355 a single record has been written.
3356 SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write
3357 retries use the same buffer location.
3358 (But all of the contents must be
3362 *) Bugfix: SSL_set_mode ignored its parameter, only SSL_CTX_set_mode
3365 *) Fix problems with no-hmac etc.
3366 [Ulf Möller, pointed out by Brian Wellington <bwelling@tislabs.com>]
3368 *) New functions RSA_get_default_method(), RSA_set_method() and
3369 RSA_get_method(). These allows replacement of RSA_METHODs without having
3370 to mess around with the internals of an RSA structure.
3373 *) Fix memory leaks in DSA_do_sign and DSA_is_prime.
3374 Also really enable memory leak checks in openssl.c and in some
3376 [Chad C. Mulligan, Bodo Moeller]
3378 *) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess
3379 up the length of negative integers. This has now been simplified to just
3380 store the length when it is first determined and use it later, rather
3381 than trying to keep track of where data is copied and updating it to
3383 [Steve Henson, reported by Brien Wheeler
3384 <bwheeler@authentica-security.com>]
3386 *) Add a new function PKCS7_signatureVerify. This allows the verification
3387 of a PKCS#7 signature but with the signing certificate passed to the
3388 function itself. This contrasts with PKCS7_dataVerify which assumes the
3389 certificate is present in the PKCS#7 structure. This isn't always the
3390 case: certificates can be omitted from a PKCS#7 structure and be
3391 distributed by "out of band" means (such as a certificate database).
3394 *) Complete the PEM_* macros with DECLARE_PEM versions to replace the
3395 function prototypes in pem.h, also change util/mkdef.pl to add the
3396 necessary function names.
3399 *) mk1mf.pl (used by Windows builds) did not properly read the
3400 options set by Configure in the top level Makefile, and Configure
3401 was not even able to write more than one option correctly.
3402 Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended.
3405 *) New functions CONF_load_bio() and CONF_load_fp() to allow a config
3406 file to be loaded from a BIO or FILE pointer. The BIO version will
3407 for example allow memory BIOs to contain config info.
3410 *) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS.
3411 Whoever hopes to achieve shared-library compatibility across versions
3412 must use this, not the compile-time macro.
3413 (Exercise 0.9.4: Which is the minimum library version required by
3415 Note: All this applies only to multi-threaded programs, others don't
3419 *) Add missing case to s3_clnt.c state machine -- one of the new SSL tests
3420 through a BIO pair triggered the default case, i.e.
3421 SSLerr(...,SSL_R_UNKNOWN_STATE).
3424 *) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications
3425 can use the SSL library even if none of the specific BIOs is
3429 *) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value
3430 for the encoded length.
3431 [Jeon KyoungHo <khjeon@sds.samsung.co.kr>]
3433 *) Add initial documentation of the X509V3 functions.
3436 *) Add a new pair of functions PEM_write_PKCS8PrivateKey() and
3437 PEM_write_bio_PKCS8PrivateKey() that are equivalent to
3438 PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more
3439 secure PKCS#8 private key format with a high iteration count.
3442 *) Fix determination of Perl interpreter: A perl or perl5
3443 _directory_ in $PATH was also accepted as the interpreter.
3444 [Ralf S. Engelschall]
3446 *) Fix demos/sign/sign.c: well there wasn't anything strictly speaking
3447 wrong with it but it was very old and did things like calling
3448 PEM_ASN1_read() directly and used MD5 for the hash not to mention some
3452 *) Fix demos/selfsign.c: it used obsolete and deleted functions, changed
3453 to use the new extension code.
3456 *) Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c
3457 with macros. This should make it easier to change their form, add extra
3458 arguments etc. Fix a few PEM prototypes which didn't have cipher as a
3462 *) Add to configuration table a new entry that can specify an alternative
3463 name for unistd.h (for pre-POSIX systems); we need this for NeXTstep,
3464 according to Mark Crispin <MRC@Panda.COM>.
3468 *) DES CBC did not update the IV. Weird.
3471 des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does.
3472 Changing the behaviour of the former might break existing programs --
3473 where IV updating is needed, des_ncbc_encrypt can be used.
3476 *) When bntest is run from "make test" it drives bc to check its
3477 calculations, as well as internally checking them. If an internal check
3478 fails, it needs to cause bc to give a non-zero result or make test carries
3479 on without noticing the failure. Fixed.
3482 *) DES library cleanups.
3485 *) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be
3486 used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit
3487 ciphers. NOTE: although the key derivation function has been verified
3488 against some published test vectors it has not been extensively tested
3489 yet. Added a -v2 "cipher" option to pkcs8 application to allow the use
3493 *) Instead of "mkdir -p", which is not fully portable, use new
3494 Perl script "util/mkdir-p.pl".
3497 *) Rewrite the way password based encryption (PBE) is handled. It used to
3498 assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter
3499 structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms
3500 but doesn't apply to PKCS#5 v2.0 where it can be something else. Now
3501 the 'parameter' field of the AlgorithmIdentifier is passed to the
3502 underlying key generation function so it must do its own ASN1 parsing.
3503 This has also changed the EVP_PBE_CipherInit() function which now has a
3504 'parameter' argument instead of literal salt and iteration count values
3505 and the function EVP_PBE_ALGOR_CipherInit() has been deleted.
3508 *) Support for PKCS#5 v1.5 compatible password based encryption algorithms
3509 and PKCS#8 functionality. New 'pkcs8' application linked to openssl.
3510 Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE
3511 KEY" because this clashed with PKCS#8 unencrypted string. Since this
3512 value was just used as a "magic string" and not used directly its
3513 value doesn't matter.
3516 *) Introduce some semblance of const correctness to BN. Shame C doesn't
3520 *) "linux-sparc64" configuration (ultrapenguin).
3521 [Ray Miller <ray.miller@oucs.ox.ac.uk>]
3522 "linux-sparc" configuration.
3523 [Christian Forster <fo@hawo.stw.uni-erlangen.de>]
3525 *) config now generates no-xxx options for missing ciphers.
3528 *) Support the EBCDIC character set (work in progress).
3529 File ebcdic.c not yet included because it has a different license.
3530 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
3532 *) Support BS2000/OSD-POSIX.
3533 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
3535 *) Make callbacks for key generation use void * instead of char *.
3538 *) Make S/MIME samples compile (not yet tested).
3541 *) Additional typesafe stacks.
3544 *) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x).
3548 Changes between 0.9.3 and 0.9.3a [29 May 1999]
3550 *) New configuration variant "sco5-gcc".
3552 *) Updated some demos.
3553 [Sean O Riordain, Wade Scholine]
3555 *) Add missing BIO_free at exit of pkcs12 application.
3558 *) Fix memory leak in conf.c.
3561 *) Updates for Win32 to assembler version of MD5.
3564 *) Set #! path to perl in apps/der_chop to where we found it
3565 instead of using a fixed path.
3568 *) SHA library changes for irix64-mips4-cc.
3571 *) Improvements for VMS support.
3575 Changes between 0.9.2b and 0.9.3 [24 May 1999]
3577 *) Bignum library bug fix. IRIX 6 passes "make test" now!
3578 This also avoids the problems with SC4.2 and unpatched SC5.
3579 [Andy Polyakov <appro@fy.chalmers.se>]
3581 *) New functions sk_num, sk_value and sk_set to replace the previous macros.
3582 These are required because of the typesafe stack would otherwise break
3583 existing code. If old code used a structure member which used to be STACK
3584 and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with
3585 sk_num or sk_value it would produce an error because the num, data members
3586 are not present in STACK_OF. Now it just produces a warning. sk_set
3587 replaces the old method of assigning a value to sk_value
3588 (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code
3589 that does this will no longer work (and should use sk_set instead) but
3590 this could be regarded as a "questionable" behaviour anyway.
3593 *) Fix most of the other PKCS#7 bugs. The "experimental" code can now
3594 correctly handle encrypted S/MIME data.
3597 *) Change type of various DES function arguments from des_cblock
3598 (which means, in function argument declarations, pointer to char)
3599 to des_cblock * (meaning pointer to array with 8 char elements),
3600 which allows the compiler to do more typechecking; it was like
3601 that back in SSLeay, but with lots of ugly casts.
3603 Introduce new type const_des_cblock.
3606 *) Reorganise the PKCS#7 library and get rid of some of the more obvious
3607 problems: find RecipientInfo structure that matches recipient certificate
3608 and initialise the ASN1 structures properly based on passed cipher.
3611 *) Belatedly make the BN tests actually check the results.
3614 *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion
3615 to and from BNs: it was completely broken. New compilation option
3616 NEG_PUBKEY_BUG to allow for some broken certificates that encode public
3617 key elements as negative integers.
3620 *) Reorganize and speed up MD5.
3621 [Andy Polyakov <appro@fy.chalmers.se>]
3624 [Richard Levitte <richard@levitte.org>]
3626 *) New option -out to asn1parse to allow the parsed structure to be
3627 output to a file. This is most useful when combined with the -strparse
3628 option to examine the output of things like OCTET STRINGS.
3631 *) Make SSL library a little more fool-proof by not requiring any longer
3632 that SSL_set_{accept,connect}_state be called before
3633 SSL_{accept,connect} may be used (SSL_set_..._state is omitted
3634 in many applications because usually everything *appeared* to work as
3635 intended anyway -- now it really works as intended).
3638 *) Move openssl.cnf out of lib/.
3641 *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall
3642 -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
3643 -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+
3644 [Ralf S. Engelschall]
3646 *) Various fixes to the EVP and PKCS#7 code. It may now be able to
3647 handle PKCS#7 enveloped data properly.
3648 [Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve]
3650 *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
3651 copying pointers. The cert_st handling is changed by this in
3652 various ways (and thus what used to be known as ctx->default_cert
3653 is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
3654 any longer when s->cert does not give us what we need).
3655 ssl_cert_instantiate becomes obsolete by this change.
3656 As soon as we've got the new code right (possibly it already is?),
3657 we have solved a couple of bugs of the earlier code where s->cert
3658 was used as if it could not have been shared with other SSL structures.
3660 Note that using the SSL API in certain dirty ways now will result
3661 in different behaviour than observed with earlier library versions:
3662 Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
3663 does not influence s as it used to.
3665 In order to clean up things more thoroughly, inside SSL_SESSION
3666 we don't use CERT any longer, but a new structure SESS_CERT
3667 that holds per-session data (if available); currently, this is
3668 the peer's certificate chain and, for clients, the server's certificate
3669 and temporary key. CERT holds only those values that can have
3670 meaningful defaults in an SSL_CTX.
3673 *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure
3674 from the internal representation. Various PKCS#7 fixes: remove some
3675 evil casts and set the enc_dig_alg field properly based on the signing
3679 *) Allow PKCS#12 password to be set from the command line or the
3680 environment. Let 'ca' get its config file name from the environment
3681 variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req'
3685 *) Allow certificate policies extension to use an IA5STRING for the
3686 organization field. This is contrary to the PKIX definition but
3687 VeriSign uses it and IE5 only recognises this form. Document 'x509'
3691 *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic,
3692 without disallowing inline assembler and the like for non-pedantic builds.
3695 *) Support Borland C++ builder.
3696 [Janez Jere <jj@void.si>, modified by Ulf Möller]
3701 *) SHA-1 cleanups and performance enhancements.
3702 [Andy Polyakov <appro@fy.chalmers.se>]
3704 *) Sparc v8plus assembler for the bignum library.
3705 [Andy Polyakov <appro@fy.chalmers.se>]
3707 *) Accept any -xxx and +xxx compiler options in Configure.
3710 *) Update HPUX configuration.
3713 *) Add missing sk_<type>_unshift() function to safestack.h
3714 [Ralf S. Engelschall]
3716 *) New function SSL_CTX_use_certificate_chain_file that sets the
3717 "extra_cert"s in addition to the certificate. (This makes sense
3718 only for "PEM" format files, as chains as a whole are not
3722 *) Support verify_depth from the SSL API.
3723 x509_vfy.c had what can be considered an off-by-one-error:
3724 Its depth (which was not part of the external interface)
3725 was actually counting the number of certificates in a chain;
3726 now it really counts the depth.
3729 *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used
3730 instead of X509err, which often resulted in confusing error
3731 messages since the error codes are not globally unique
3732 (e.g. an alleged error in ssl3_accept when a certificate
3733 didn't match the private key).
3735 *) New function SSL_CTX_set_session_id_context that allows to set a default
3736 value (so that you don't need SSL_set_session_id_context for each
3737 connection using the SSL_CTX).
3740 *) OAEP decoding bug fix.
3743 *) Support INSTALL_PREFIX for package builders, as proposed by
3747 *) New Configure options "threads" and "no-threads". For systems
3748 where the proper compiler options are known (currently Solaris
3749 and Linux), "threads" is the default.
3752 *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
3755 *) Install various scripts to $(OPENSSLDIR)/misc, not to
3756 $(INSTALLTOP)/bin -- they shouldn't clutter directories
3757 such as /usr/local/bin.
3760 *) "make linux-shared" to build shared libraries.
3761 [Niels Poppe <niels@netbox.org>]
3763 *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
3766 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
3767 extension adding in x509 utility.
3770 *) Remove NOPROTO sections and error code comments.
3773 *) Partial rewrite of the DEF file generator to now parse the ANSI
3777 *) New Configure options --prefix=DIR and --openssldir=DIR.
3780 *) Complete rewrite of the error code script(s). It is all now handled
3781 by one script at the top level which handles error code gathering,
3782 header rewriting and C source file generation. It should be much better
3783 than the old method: it now uses a modified version of Ulf's parser to
3784 read the ANSI prototypes in all header files (thus the old K&R definitions
3785 aren't needed for error creation any more) and do a better job of
3786 translating function codes into names. The old 'ASN1 error code imbedded
3787 in a comment' is no longer necessary and it doesn't use .err files which
3788 have now been deleted. Also the error code call doesn't have to appear all
3789 on one line (which resulted in some large lines...).
3792 *) Change #include filenames from <foo.h> to <openssl/foo.h>.
3795 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
3796 0 (which usually indicates a closed connection), but continue reading.
3799 *) Fix some race conditions.
3802 *) Add support for CRL distribution points extension. Add Certificate
3803 Policies and CRL distribution points documentation.
3806 *) Move the autogenerated header file parts to crypto/opensslconf.h.
3809 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
3810 8 of keying material. Merlin has also confirmed interop with this fix
3811 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
3812 [Merlin Hughes <merlin@baltimore.ie>]
3814 *) Fix lots of warnings.
3815 [Richard Levitte <levitte@stacken.kth.se>]
3817 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
3818 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
3819 [Richard Levitte <levitte@stacken.kth.se>]
3821 *) Fix problems with sizeof(long) == 8.
3822 [Andy Polyakov <appro@fy.chalmers.se>]
3824 *) Change functions to ANSI C.
3827 *) Fix typos in error codes.
3828 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
3830 *) Remove defunct assembler files from Configure.
3833 *) SPARC v8 assembler BIGNUM implementation.
3834 [Andy Polyakov <appro@fy.chalmers.se>]
3836 *) Support for Certificate Policies extension: both print and set.
3837 Various additions to support the r2i method this uses.
3840 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
3841 return a const string when you are expecting an allocated buffer.
3844 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
3845 types DirectoryString and DisplayText.
3848 *) Add code to allow r2i extensions to access the configuration database,
3849 add an LHASH database driver and add several ctx helper functions.
3852 *) Fix an evil bug in bn_expand2() which caused various BN functions to
3853 fail when they extended the size of a BIGNUM.
3856 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
3857 support typesafe stack.
3860 *) Fix typo in SSL_[gs]et_options().
3861 [Nils Frostberg <nils@medcom.se>]
3863 *) Delete various functions and files that belonged to the (now obsolete)
3864 old X509V3 handling code.
3867 *) New Configure option "rsaref".
3870 *) Don't auto-generate pem.h.
3873 *) Introduce type-safe ASN.1 SETs.
3876 *) Convert various additional casted stacks to type-safe STACK_OF() variants.
3877 [Ben Laurie, Ralf S. Engelschall, Steve Henson]
3879 *) Introduce type-safe STACKs. This will almost certainly break lots of code
3880 that links with OpenSSL (well at least cause lots of warnings), but fear
3881 not: the conversion is trivial, and it eliminates loads of evil casts. A
3882 few STACKed things have been converted already. Feel free to convert more.
3883 In the fullness of time, I'll do away with the STACK type altogether.
3886 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
3887 specified in <certfile> by updating the entry in the index.txt file.
3888 This way one no longer has to edit the index.txt file manually for
3889 revoking a certificate. The -revoke option does the gory details now.
3890 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
3892 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
3893 `-text' option at all and this way the `-noout -text' combination was
3894 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
3895 [Ralf S. Engelschall]
3897 *) Make sure a corresponding plain text error message exists for the
3898 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
3899 verify callback function determined that a certificate was revoked.
3900 [Ralf S. Engelschall]
3902 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
3903 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
3904 all available cipers including rc5, which was forgotten until now.
3905 In order to let the testing shell script know which algorithms
3906 are available, a new (up to now undocumented) command
3907 "openssl list-cipher-commands" is used.
3910 *) Bugfix: s_client occasionally would sleep in select() when
3911 it should have checked SSL_pending() first.
3914 *) New functions DSA_do_sign and DSA_do_verify to provide access to
3915 the raw DSA values prior to ASN.1 encoding.
3918 *) Tweaks to Configure
3919 [Niels Poppe <niels@netbox.org>]
3921 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
3925 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
3928 *) New config option to avoid instructions that are illegal on the 80386.
3929 The default code is faster, but requires at least a 486.
3932 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
3933 SSL2_SERVER_VERSION (not used at all) macros, which are now the
3934 same as SSL2_VERSION anyway.
3937 *) New "-showcerts" option for s_client.
3940 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
3941 application. Various cleanups and fixes.
3944 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
3945 modify error routines to work internally. Add error codes and PBE init
3946 to library startup routines.
3949 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
3950 packing functions to asn1 and evp. Changed function names and error
3951 codes along the way.
3954 *) PKCS12 integration: and so it begins... First of several patches to
3955 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
3956 objects to objects.h
3959 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
3960 and display support for Thawte strong extranet extension.
3963 *) Add LinuxPPC support.
3964 [Jeff Dubrule <igor@pobox.org>]
3966 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
3967 bn_div_words in alpha.s.
3968 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
3970 *) Make sure the RSA OAEP test is skipped under -DRSAref because
3971 OAEP isn't supported when OpenSSL is built with RSAref.
3972 [Ulf Moeller <ulf@fitug.de>]
3974 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
3975 so they no longer are missing under -DNOPROTO.
3976 [Soren S. Jorvang <soren@t.dk>]
3979 Changes between 0.9.1c and 0.9.2b [22 Mar 1999]
3981 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
3982 doesn't work when the session is reused. Coming soon!
3985 *) Fix a security hole, that allows sessions to be reused in the wrong
3986 context thus bypassing client cert protection! All software that uses
3987 client certs and session caches in multiple contexts NEEDS PATCHING to
3988 allow session reuse! A fuller solution is in the works.
3989 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
3991 *) Some more source tree cleanups (removed obsolete files
3992 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
3993 permission on "config" script to be executable) and a fix for the INSTALL
3995 [Ulf Moeller <ulf@fitug.de>]
3997 *) Remove some legacy and erroneous uses of malloc, free instead of
3999 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
4001 *) Make rsa_oaep_test return non-zero on error.
4002 [Ulf Moeller <ulf@fitug.de>]
4004 *) Add support for native Solaris shared libraries. Configure
4005 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
4006 if someone would make that last step automatic.
4007 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
4009 *) ctx_size was not built with the right compiler during "make links". Fixed.
4012 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
4013 except NULL ciphers". This means the default cipher list will no longer
4014 enable NULL ciphers. They need to be specifically enabled e.g. with
4015 the string "DEFAULT:eNULL".
4018 *) Fix to RSA private encryption routines: if p < q then it would
4019 occasionally produce an invalid result. This will only happen with
4020 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
4023 *) Be less restrictive and allow also `perl util/perlpath.pl
4024 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
4025 because this way one can also use an interpreter named `perl5' (which is
4026 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
4027 installed as `perl').
4028 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
4030 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
4031 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
4033 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
4034 advapi32.lib to Win32 build and change the pem test comparision
4035 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
4036 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
4037 and crypto/des/ede_cbcm_enc.c.
4040 *) DES quad checksum was broken on big-endian architectures. Fixed.
4043 *) Comment out two functions in bio.h that aren't implemented. Fix up the
4044 Win32 test batch file so it (might) work again. The Win32 test batch file
4045 is horrible: I feel ill....
4048 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
4049 in e_os.h. Audit of header files to check ANSI and non ANSI
4050 sections: 10 functions were absent from non ANSI section and not exported
4051 from Windows DLLs. Fixed up libeay.num for new functions.
4054 *) Make `openssl version' output lines consistent.
4055 [Ralf S. Engelschall]
4057 *) Fix Win32 symbol export lists for BIO functions: Added
4058 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
4059 to ms/libeay{16,32}.def.
4060 [Ralf S. Engelschall]
4062 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
4063 fine under Unix and passes some trivial tests I've now added. But the
4064 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
4065 added to make sure no one expects that this stuff really works in the
4066 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
4067 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
4069 [Ralf S. Engelschall]
4071 *) Fix the generation of two part addresses in perl.
4072 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
4074 *) Add config entry for Linux on MIPS.
4075 [John Tobey <jtobey@channel1.com>]
4077 *) Make links whenever Configure is run, unless we are on Windoze.
4080 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
4081 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
4085 *) Add a useful kludge to allow package maintainers to specify compiler and
4086 other platforms details on the command line without having to patch the
4087 Configure script everytime: One now can use ``perl Configure
4088 <id>:<details>'', i.e. platform ids are allowed to have details appended
4089 to them (seperated by colons). This is treated as there would be a static
4090 pre-configured entry in Configure's %table under key <id> with value
4091 <details> and ``perl Configure <id>'' is called. So, when you want to
4092 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
4093 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
4094 now, which overrides the FreeBSD-elf entry on-the-fly.
4095 [Ralf S. Engelschall]
4097 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
4100 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
4101 on the `perl Configure ...' command line. This way one can compile
4102 OpenSSL libraries with Position Independent Code (PIC) which is needed
4103 for linking it into DSOs.
4104 [Ralf S. Engelschall]
4106 *) Remarkably, export ciphers were totally broken and no-one had noticed!
4110 *) Cleaned up the LICENSE document: The official contact for any license
4111 questions now is the OpenSSL core team under openssl-core@openssl.org.
4112 And add a paragraph about the dual-license situation to make sure people
4113 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
4114 to the OpenSSL toolkit.
4115 [Ralf S. Engelschall]
4117 *) General source tree makefile cleanups: Made `making xxx in yyy...'
4118 display consistent in the source tree and replaced `/bin/rm' by `rm'.
4119 Additonally cleaned up the `make links' target: Remove unnecessary
4120 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
4121 to speed processing and no longer clutter the display with confusing
4122 stuff. Instead only the actually done links are displayed.
4123 [Ralf S. Engelschall]
4125 *) Permit null encryption ciphersuites, used for authentication only. It used
4126 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
4127 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
4131 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
4132 signed attributes when verifying signatures (this would break them),
4133 the detached data encoding was wrong and public keys obtained using
4134 X509_get_pubkey() weren't freed.
4137 *) Add text documentation for the BUFFER functions. Also added a work around
4138 to a Win95 console bug. This was triggered by the password read stuff: the
4139 last character typed gets carried over to the next fread(). If you were
4140 generating a new cert request using 'req' for example then the last
4141 character of the passphrase would be CR which would then enter the first
4145 *) Added the new `Includes OpenSSL Cryptography Software' button as
4146 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
4147 button and can be used by applications based on OpenSSL to show the
4148 relationship to the OpenSSL project.
4149 [Ralf S. Engelschall]
4151 *) Remove confusing variables in function signatures in files
4152 ssl/ssl_lib.c and ssl/ssl.h.
4153 [Lennart Bong <lob@kulthea.stacken.kth.se>]
4155 *) Don't install bss_file.c under PREFIX/include/
4156 [Lennart Bong <lob@kulthea.stacken.kth.se>]
4158 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
4159 functions that return function pointers and has support for NT specific
4160 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
4161 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
4162 unsigned to signed types: this was killing the Win32 compile.
4165 *) Add new certificate file to stack functions,
4166 SSL_add_dir_cert_subjects_to_stack() and
4167 SSL_add_file_cert_subjects_to_stack(). These largely supplant
4168 SSL_load_client_CA_file(), and can be used to add multiple certs easily
4169 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
4170 This means that Apache-SSL and similar packages don't have to mess around
4171 to add as many CAs as they want to the preferred list.
4174 *) Experiment with doxygen documentation. Currently only partially applied to
4176 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
4177 openssl.doxy as the configuration file.
4180 *) Get rid of remaining C++-style comments which strict C compilers hate.
4181 [Ralf S. Engelschall, pointed out by Carlos Amengual]
4183 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
4184 compiled in by default: it has problems with large keys.
4187 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
4188 DH private keys and/or callback functions which directly correspond to
4189 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
4190 is needed for applications which have to configure certificates on a
4191 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
4193 For the RSA certificate situation is makes no difference, but
4194 for the DSA certificate situation this fixes the "no shared cipher"
4195 problem where the OpenSSL cipher selection procedure failed because the
4196 temporary keys were not overtaken from the context and the API provided
4197 no way to reconfigure them.
4198 The new functions now let applications reconfigure the stuff and they
4199 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
4200 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
4201 non-public-API function ssl_cert_instantiate() is used as a helper
4202 function and also to reduce code redundancy inside ssl_rsa.c.
4203 [Ralf S. Engelschall]
4205 *) Move s_server -dcert and -dkey options out of the undocumented feature
4206 area because they are useful for the DSA situation and should be
4207 recognized by the users.
4208 [Ralf S. Engelschall]
4210 *) Fix the cipher decision scheme for export ciphers: the export bits are
4211 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
4212 SSL_EXP_MASK. So, the original variable has to be used instead of the
4213 already masked variable.
4214 [Richard Levitte <levitte@stacken.kth.se>]
4216 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
4217 [Richard Levitte <levitte@stacken.kth.se>]
4219 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
4220 from `int' to `unsigned int' because it's a length and initialized by
4221 EVP_DigestFinal() which expects an `unsigned int *'.
4222 [Richard Levitte <levitte@stacken.kth.se>]
4224 *) Don't hard-code path to Perl interpreter on shebang line of Configure
4225 script. Instead use the usual Shell->Perl transition trick.
4226 [Ralf S. Engelschall]
4228 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
4229 (in addition to RSA certificates) to match the behaviour of `openssl dsa
4230 -noout -modulus' as it's already the case for `openssl rsa -noout
4231 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
4232 currently the public key is printed (a decision which was already done by
4233 `openssl dsa -modulus' in the past) which serves a similar purpose.
4234 Additionally the NO_RSA no longer completely removes the whole -modulus
4235 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
4237 [Ralf S. Engelschall]
4239 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
4240 BIO. See the source (crypto/evp/bio_ok.c) for more info.
4241 [Arne Ansper <arne@ats.cyber.ee>]
4243 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
4244 to be added. Now both 'req' and 'ca' can use new objects defined in the
4248 *) Add cool BIO that does syslog (or event log on NT).
4249 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
4251 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
4252 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
4253 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
4254 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
4257 *) Add preliminary config info for new extension code.
4260 *) Make RSA_NO_PADDING really use no padding.
4261 [Ulf Moeller <ulf@fitug.de>]
4263 *) Generate errors when private/public key check is done.
4266 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
4267 for some CRL extensions and new objects added.
4270 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
4271 key usage extension and fuller support for authority key id.
4274 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
4275 padding method for RSA, which is recommended for new applications in PKCS
4276 #1 v2.0 (RFC 2437, October 1998).
4277 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
4278 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
4279 against Bleichbacher's attack on RSA.
4280 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
4283 *) Updates to the new SSL compression code
4284 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
4286 *) Fix so that the version number in the master secret, when passed
4287 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
4288 (because the server will not accept higher), that the version number
4289 is 0x03,0x01, not 0x03,0x00
4290 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
4292 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
4293 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
4294 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
4297 *) Support for RAW extensions where an arbitrary extension can be
4298 created by including its DER encoding. See apps/openssl.cnf for
4302 *) Make sure latest Perl versions don't interpret some generated C array
4303 code as Perl array code in the crypto/err/err_genc.pl script.
4304 [Lars Weber <3weber@informatik.uni-hamburg.de>]
4306 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
4307 not many people have the assembler. Various Win32 compilation fixes and
4308 update to the INSTALL.W32 file with (hopefully) more accurate Win32
4312 *) Modify configure script 'Configure' to automatically create crypto/date.h
4313 file under Win32 and also build pem.h from pem.org. New script
4314 util/mkfiles.pl to create the MINFO file on environments that can't do a
4315 'make files': perl util/mkfiles.pl >MINFO should work.
4318 *) Major rework of DES function declarations, in the pursuit of correctness
4319 and purity. As a result, many evil casts evaporated, and some weirdness,
4320 too. You may find this causes warnings in your code. Zapping your evil
4321 casts will probably fix them. Mostly.
4324 *) Fix for a typo in asn1.h. Bug fix to object creation script
4325 obj_dat.pl. It considered a zero in an object definition to mean
4326 "end of object": none of the objects in objects.h have any zeros
4327 so it wasn't spotted.
4328 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
4330 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
4331 Masking (CBCM). In the absence of test vectors, the best I have been able
4332 to do is check that the decrypt undoes the encrypt, so far. Send me test
4333 vectors if you have them.
4336 *) Correct calculation of key length for export ciphers (too much space was
4337 allocated for null ciphers). This has not been tested!
4340 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
4341 message is now correct (it understands "crypto" and "ssl" on its
4342 command line). There is also now an "update" option. This will update
4343 the util/ssleay.num and util/libeay.num files with any new functions.
4345 perl util/mkdef.pl crypto ssl update
4346 it will update them.
4349 *) Overhauled the Perl interface (perl/*):
4350 - ported BN stuff to OpenSSL's different BN library
4351 - made the perl/ source tree CVS-aware
4352 - renamed the package from SSLeay to OpenSSL (the files still contain
4353 their history because I've copied them in the repository)
4354 - removed obsolete files (the test scripts will be replaced
4355 by better Test::Harness variants in the future)
4356 [Ralf S. Engelschall]
4358 *) First cut for a very conservative source tree cleanup:
4359 1. merge various obsolete readme texts into doc/ssleay.txt
4360 where we collect the old documents and readme texts.
4361 2. remove the first part of files where I'm already sure that we no
4362 longer need them because of three reasons: either they are just temporary
4363 files which were left by Eric or they are preserved original files where
4364 I've verified that the diff is also available in the CVS via "cvs diff
4365 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
4366 the crypto/md/ stuff).
4367 [Ralf S. Engelschall]
4369 *) More extension code. Incomplete support for subject and issuer alt
4370 name, issuer and authority key id. Change the i2v function parameters
4371 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
4372 what that's for :-) Fix to ASN1 macro which messed up
4373 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
4376 *) Preliminary support for ENUMERATED type. This is largely copied from the
4380 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
4381 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
4383 *) Make sure `make rehash' target really finds the `openssl' program.
4384 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
4386 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
4387 like to hear about it if this slows down other processors.
4390 *) Add CygWin32 platform information to Configure script.
4391 [Alan Batie <batie@aahz.jf.intel.com>]
4393 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
4394 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
4396 *) New program nseq to manipulate netscape certificate sequences
4399 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
4403 *) Fixes to BN code. Previously the default was to define BN_RECURSION
4404 but the BN code had some problems that would cause failures when
4405 doing certificate verification and some other functions.
4406 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
4408 *) Add ASN1 and PEM code to support netscape certificate sequences.
4411 *) Add ASN1 and PEM code to support netscape certificate sequences.
4414 *) Add several PKIX and private extended key usage OIDs.
4417 *) Modify the 'ca' program to handle the new extension code. Modify
4418 openssl.cnf for new extension format, add comments.
4421 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
4422 and add a sample to openssl.cnf so req -x509 now adds appropriate
4426 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
4427 error code, add initial support to X509_print() and x509 application.
4430 *) Takes a deep breath and start addding X509 V3 extension support code. Add
4431 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
4432 stuff is currently isolated and isn't even compiled yet.
4435 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
4436 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
4437 Removed the versions check from X509 routines when loading extensions:
4438 this allows certain broken certificates that don't set the version
4439 properly to be processed.
4442 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
4443 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
4444 can still be regenerated with "make depend".
4447 *) Spelling mistake in C version of CAST-128.
4448 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
4450 *) Changes to the error generation code. The perl script err-code.pl
4451 now reads in the old error codes and retains the old numbers, only
4452 adding new ones if necessary. It also only changes the .err files if new
4453 codes are added. The makefiles have been modified to only insert errors
4454 when needed (to avoid needlessly modifying header files). This is done
4455 by only inserting errors if the .err file is newer than the auto generated
4456 C file. To rebuild all the error codes from scratch (the old behaviour)
4457 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
4458 or delete all the .err files.
4461 *) CAST-128 was incorrectly implemented for short keys. The C version has
4462 been fixed, but is untested. The assembler versions are also fixed, but
4463 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
4464 to regenerate it if needed.
4465 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
4466 Hagino <itojun@kame.net>]
4468 *) File was opened incorrectly in randfile.c.
4469 [Ulf Möller <ulf@fitug.de>]
4471 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
4472 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
4473 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
4474 al: it's just almost always a UTCTime. Note this patch adds new error
4475 codes so do a "make errors" if there are problems.
4478 *) Correct Linux 1 recognition in config.
4479 [Ulf Möller <ulf@fitug.de>]
4481 *) Remove pointless MD5 hash when using DSA keys in ca.
4482 [Anonymous <nobody@replay.com>]
4484 *) Generate an error if given an empty string as a cert directory. Also
4485 generate an error if handed NULL (previously returned 0 to indicate an
4486 error, but didn't set one).
4487 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
4489 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
4492 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
4493 parameters. This was causing a warning which killed off the Win32 compile.
4496 *) Remove C++ style comments from crypto/bn/bn_local.h.
4497 [Neil Costigan <neil.costigan@celocom.com>]
4499 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
4500 based on a text string, looking up short and long names and finally
4501 "dot" format. The "dot" format stuff didn't work. Added new function
4502 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
4503 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
4504 OID is not part of the table.
4507 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
4508 X509_LOOKUP_by_alias().
4511 *) Sort openssl functions by name.
4514 *) Get the gendsa program working (hopefully) and add it to app list. Remove
4515 encryption from sample DSA keys (in case anyone is interested the password
4519 *) Make _all_ *_free functions accept a NULL pointer.
4520 [Frans Heymans <fheymans@isaserver.be>]
4522 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
4524 [Anonymous <nobody@replay.com>]
4526 *) s_server should send the CAfile as acceptable CAs, not its own cert.
4527 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
4529 *) Don't blow it for numeric -newkey arguments to apps/req.
4530 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
4532 *) Temp key "for export" tests were wrong in s3_srvr.c.
4533 [Anonymous <nobody@replay.com>]
4535 *) Add prototype for temp key callback functions
4536 SSL_CTX_set_tmp_{rsa,dh}_callback().
4539 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
4540 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
4543 *) X509_name_add_entry() freed the wrong thing after an error.
4544 [Arne Ansper <arne@ats.cyber.ee>]
4546 *) rsa_eay.c would attempt to free a NULL context.
4547 [Arne Ansper <arne@ats.cyber.ee>]
4549 *) BIO_s_socket() had a broken should_retry() on Windoze.
4550 [Arne Ansper <arne@ats.cyber.ee>]
4552 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
4553 [Arne Ansper <arne@ats.cyber.ee>]
4555 *) Make sure the already existing X509_STORE->depth variable is initialized
4556 in X509_STORE_new(), but document the fact that this variable is still
4557 unused in the certificate verification process.
4558 [Ralf S. Engelschall]
4560 *) Fix the various library and apps files to free up pkeys obtained from
4561 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
4564 *) Fix reference counting in X509_PUBKEY_get(). This makes
4565 demos/maurice/example2.c work, amongst others, probably.
4566 [Steve Henson and Ben Laurie]
4568 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
4569 `openssl' and second, the shortcut symlinks for the `openssl <command>'
4570 are no longer created. This way we have a single and consistent command
4571 line interface `openssl <command>', similar to `cvs <command>'.
4572 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
4574 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
4575 BIT STRING wrapper always have zero unused bits.
4578 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
4581 *) Make the top-level INSTALL documentation easier to understand.
4584 *) Makefiles updated to exit if an error occurs in a sub-directory
4585 make (including if user presses ^C) [Paul Sutton]
4587 *) Make Montgomery context stuff explicit in RSA data structure.
4590 *) Fix build order of pem and err to allow for generated pem.h.
4593 *) Fix renumbering bug in X509_NAME_delete_entry().
4596 *) Enhanced the err-ins.pl script so it makes the error library number
4597 global and can add a library name. This is needed for external ASN1 and
4598 other error libraries.
4601 *) Fixed sk_insert which never worked properly.
4604 *) Fix ASN1 macros so they can handle indefinite length construted
4605 EXPLICIT tags. Some non standard certificates use these: they can now
4609 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
4610 into a single doc/ssleay.txt bundle. This way the information is still
4611 preserved but no longer messes up this directory. Now it's new room for
4612 the new set of documenation files.
4613 [Ralf S. Engelschall]
4615 *) SETs were incorrectly DER encoded. This was a major pain, because they
4616 shared code with SEQUENCEs, which aren't coded the same. This means that
4617 almost everything to do with SETs or SEQUENCEs has either changed name or
4618 number of arguments.
4619 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
4621 *) Fix test data to work with the above.
4624 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
4625 was already fixed by Eric for 0.9.1 it seems.
4626 [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
4628 *) Autodetect FreeBSD3.
4631 *) Fix various bugs in Configure. This affects the following platforms:
4635 unixware-2.0-pentium
4639 *) Eliminate generated files from CVS. Reorder tests to regenerate files
4640 before they are needed.
4643 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
4647 Changes between 0.9.1b and 0.9.1c [23-Dec-1998]
4649 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
4650 changed SSLeay to OpenSSL in version strings.
4651 [Ralf S. Engelschall]
4653 *) Some fixups to the top-level documents.
4656 *) Fixed the nasty bug where rsaref.h was not found under compile-time
4657 because the symlink to include/ was missing.
4658 [Ralf S. Engelschall]
4660 *) Incorporated the popular no-RSA/DSA-only patches
4661 which allow to compile a RSA-free SSLeay.
4662 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
4664 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
4665 when "ssleay" is still not found.
4666 [Ralf S. Engelschall]
4668 *) Added more platforms to Configure: Cray T3E, HPUX 11,
4669 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
4671 *) Updated the README file.
4672 [Ralf S. Engelschall]
4674 *) Added various .cvsignore files in the CVS repository subdirs
4675 to make a "cvs update" really silent.
4676 [Ralf S. Engelschall]
4678 *) Recompiled the error-definition header files and added
4679 missing symbols to the Win32 linker tables.
4680 [Ralf S. Engelschall]
4682 *) Cleaned up the top-level documents;
4683 o new files: CHANGES and LICENSE
4684 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
4685 o merged COPYRIGHT into LICENSE
4686 o removed obsolete TODO file
4687 o renamed MICROSOFT to INSTALL.W32
4688 [Ralf S. Engelschall]
4690 *) Removed dummy files from the 0.9.1b source tree:
4691 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
4692 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f
4693 crypto/pem/gmon.out crypto/perlasm/f crypto/pkcs7/build crypto/rsa/f
4694 crypto/sha/asm/f crypto/threads/f ms/zzz ssl/f ssl/f.mak test/f
4695 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
4696 [Ralf S. Engelschall]
4698 *) Added various platform portability fixes.
4701 *) The Genesis of the OpenSSL rpject:
4702 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
4703 Young and Tim J. Hudson created while they were working for C2Net until
4705 [The OpenSSL Project]
4708 Changes between 0.9.0b and 0.9.1b [not released]
4710 *) Updated a few CA certificates under certs/
4713 *) Changed some BIGNUM api stuff.
4716 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
4717 DGUX x86, Linux Alpha, etc.
4720 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
4721 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
4725 *) Add -strparse option to asn1pars program which parses nested
4727 [Dr Stephen Henson <shenson@bigfoot.com>]
4729 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
4732 *) DSA fix for "ca" program.
4735 *) Added "-genkey" option to "dsaparam" program.
4738 *) Added RIPE MD160 (rmd160) message digest.
4741 *) Added -a (all) option to "ssleay version" command.
4744 *) Added PLATFORM define which is the id given to Configure.
4747 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
4750 *) Extended the ASN.1 parser routines.
4753 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
4756 *) Added a BN_CTX to the BN library.
4759 *) Fixed the weak key values in DES library
4762 *) Changed API in EVP library for cipher aliases.
4765 *) Added support for RC2/64bit cipher.
4768 *) Converted the lhash library to the crypto/mem.c functions.
4771 *) Added more recognized ASN.1 object ids.
4774 *) Added more RSA padding checks for SSL/TLS.
4777 *) Added BIO proxy/filter functionality.
4780 *) Added extra_certs to SSL_CTX which can be used
4781 send extra CA certificates to the client in the CA cert chain sending
4782 process. It can be configured with SSL_CTX_add_extra_chain_cert().
4785 *) Now Fortezza is denied in the authentication phase because
4786 this is key exchange mechanism is not supported by SSLeay at all.
4789 *) Additional PKCS1 checks.
4792 *) Support the string "TLSv1" for all TLS v1 ciphers.
4795 *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
4796 ex_data index of the SSL context in the X509_STORE_CTX ex_data.
4799 *) Fixed a few memory leaks.
4802 *) Fixed various code and comment typos.
4805 *) A minor bug in ssl/s3_clnt.c where there would always be 4 0
