5 Changes between 0.9.5a and 0.9.6 [xx XXX 2000]
7 *) When some versions of IIS use the 'NET' form of private key the
8 key derivation algorithm is different. Normally MD5(password) is
9 used as a 128 bit RC4 key. In the modified case
10 MD5(MD5(password) + "SGCKEYSALT") is used insted. Added some
11 new functions i2d_RSA_NET(), d2i_RSA_NET() etc which are the same
12 as the old Netscape_RSA functions except they have an additional
13 'sgckey' parameter which uses the modified algorithm. Also added
14 an -sgckey command line option to the rsa utility. Thanks to
15 Adrian Peck <bertie@ncipher.com> for posting details of the modified
16 algorithm to openssl-dev.
19 *) The evp_local.h macros were using 'c.##kname' which resulted in
20 invalid expansion on some systems (SCO 5.0.5 for example).
21 Corrected to 'c.kname'.
22 [Phillip Porch <root@theporch.com>]
24 *) New X509_get1_email() and X509_REQ_get1_email() functions that return
25 a STACK of email addresses from a certificate or request, these look
26 in the subject name and the subject alternative name extensions and
27 omit any duplicate addresses.
30 *) Re-implement BN_mod_exp2_mont using independent (and larger) windows.
31 This makes DSA verification about 2 % faster.
34 *) Increase maximum window size in BN_mod_exp_... to 6 bits instead of 5
35 (meaning that now 2^5 values will be precomputed, which is only 4 KB
36 plus overhead for 1024 bit moduli).
37 This makes exponentiations about 0.5 % faster for 1024 bit
38 exponents (as measured by "openssl speed rsa2048").
41 *) Rename memory handling macros to avoid conflicts with other
43 Malloc => OPENSSL_malloc
44 Malloc_locked => OPENSSL_malloc_locked
45 Realloc => OPENSSL_realloc
49 *) New function BN_mod_exp_mont_word for small bases (roughly 15%
50 faster than BN_mod_exp_mont, i.e. 7% for a full DH exchange).
54 [John Jarvie <jjarvie@newsguy.com>]
56 *) The type-safe stack code has been rejigged. It is now only compiled
57 in when OpenSSL is configured with the DEBUG_SAFESTACK option and
58 by default all type-specific stack functions are "#define"d back to
59 standard stack functions. This results in more streamlined output
60 but retains the type-safety checking possibilities of the original
64 *) The STACK code has been cleaned up, and certain type declarations
65 that didn't make a lot of sense have been brought in line. This has
66 also involved a cleanup of sorts in safestack.h to more correctly
67 map type-safe stack functions onto their plain stack counterparts.
68 This work has also resulted in a variety of "const"ifications of
69 lots of the code, especially "_cmp" operations which should normally
70 be prototyped with "const" parameters anyway.
73 *) When generating bytes for the first time in md_rand.c, 'stir the pool'
74 by seeding with STATE_SIZE dummy bytes (with zero entropy count).
75 (The PRNG state consists of two parts, the large pool 'state' and 'md',
76 where all of 'md' is used each time the PRNG is used, but 'state'
77 is used only indexed by a cyclic counter. As entropy may not be
78 well distributed from the beginning, 'md' is important as a
79 chaining variable. However, the output function chains only half
80 of 'md', i.e. 80 bits. ssleay_rand_add, on the other hand, chains
81 all of 'md', and seeding with STATE_SIZE dummy bytes will result
82 in all of 'state' being rewritten, with the new values depending
83 on virtually all of 'md'. This overcomes the 80 bit limitation.)
86 *) In ssl/s2_clnt.c and ssl/s3_clnt.c, call ERR_clear_error() when
87 the handshake is continued after ssl_verify_cert_chain();
88 otherwise, if SSL_VERIFY_NONE is set, remaining error codes
89 can lead to 'unexplainable' connection aborts later.
90 [Bodo Moeller; problem tracked down by Lutz Jaenicke]
92 *) Major EVP API cipher revision.
93 Add hooks for extra EVP features. This allows various cipher
94 parameters to be set in the EVP interface. Support added for variable
95 key length ciphers via the EVP_CIPHER_CTX_set_key_length() function and
96 setting of RC2 and RC5 parameters.
98 Modify EVP_OpenInit() and EVP_SealInit() to cope with variable key length
101 Remove lots of duplicated code from the EVP library. For example *every*
102 cipher init() function handles the 'iv' in the same way according to the
103 cipher mode. They also all do nothing if the 'key' parameter is NULL and
104 for CFB and OFB modes they zero ctx->num.
106 New functionality allows removal of S/MIME code RC2 hack.
108 Most of the routines have the same form and so can be declared in terms
111 By shifting this to the top level EVP_CipherInit() it can be removed from
112 all individual ciphers. If the cipher wants to handle IVs or keys
113 differently it can set the EVP_CIPH_CUSTOM_IV or EVP_CIPH_ALWAYS_CALL_INIT
116 Change lots of functions like EVP_EncryptUpdate() to now return a
117 value: although software versions of the algorithms cannot fail
118 any installed hardware versions can.
121 *) Implement SSL_OP_TLS_ROLLBACK_BUG: In ssl3_get_client_key_exchange, if
122 this option is set, tolerate broken clients that send the negotiated
123 protocol version number instead of the requested protocol version
127 *) Call dh_tmp_cb (set by ..._TMP_DH_CB) with correct 'is_export' flag;
128 i.e. non-zero for export ciphersuites, zero otherwise.
129 Previous versions had this flag inverted, inconsistent with
130 rsa_tmp_cb (..._TMP_RSA_CB).
131 [Bodo Moeller; problem reported by Amit Chopra]
133 *) Add missing DSA library text string. Work around for some IIS
134 key files with invalid SEQUENCE encoding.
137 *) Add a document (doc/standards.txt) that list all kinds of standards
138 and so on that are implemented in OpenSSL.
141 *) Enhance c_rehash script. Old version would mishandle certificates
142 with the same subject name hash and wouldn't handle CRLs at all.
143 Added -fingerprint option to crl utility, to support new c_rehash
147 *) Eliminate non-ANSI declarations in crypto.h and stack.h.
150 *) Fix for SSL server purpose checking. Server checking was
151 rejecting certificates which had extended key usage present
152 but no ssl client purpose.
153 [Steve Henson, reported by Rene Grosser <grosser@hisolutions.com>]
155 *) Make PKCS#12 code work with no password. The PKCS#12 spec
156 is a little unclear about how a blank password is handled.
157 Since the password in encoded as a BMPString with terminating
158 double NULL a zero length password would end up as just the
159 double NULL. However no password at all is different and is
160 handled differently in the PKCS#12 key generation code. NS
161 treats a blank password as zero length. MSIE treats it as no
162 password on export: but it will try both on import. We now do
163 the same: PKCS12_parse() tries zero length and no password if
164 the password is set to "" or NULL (NULL is now a valid password:
165 it wasn't before) as does the pkcs12 application.
168 *) Bugfixes in apps/x509.c: Avoid a memory leak; and don't use
169 perror when PEM_read_bio_X509_REQ fails, the error message must
170 be obtained from the error queue.
173 *) Avoid 'thread_hash' memory leak in crypto/err/err.c by freeing
174 it in ERR_remove_state if appropriate, and change ERR_get_state
175 accordingly to avoid race conditions (this is necessary because
176 thread_hash is no longer constant once set).
179 *) Bugfix for linux-elf makefile.one.
182 *) RSA_get_default_method() will now cause a default
183 RSA_METHOD to be chosen if one doesn't exist already.
184 Previously this was only set during a call to RSA_new()
185 or RSA_new_method(NULL) meaning it was possible for
186 RSA_get_default_method() to return NULL.
189 *) Added native name translation to the existing DSO code
190 that will convert (if the flag to do so is set) filenames
191 that are sufficiently small and have no path information
192 into a canonical native form. Eg. "blah" converted to
193 "libblah.so" or "blah.dll" etc.
196 *) New function ERR_error_string_n(e, buf, len) which is like
197 ERR_error_string(e, buf), but writes at most 'len' bytes
198 including the 0 terminator. For ERR_error_string_n, 'buf'
200 [Damien Miller <djm@mindrot.org>, Bodo Moeller]
202 *) CONF library reworked to become more general. A new CONF
203 configuration file reader "class" is implemented as well as a
204 new functions (NCONF_*, for "New CONF") to handle it. The now
205 old CONF_* functions are still there, but are reimplemented to
206 work in terms of the new functions. Also, a set of functions
207 to handle the internal storage of the configuration data is
208 provided to make it easier to write new configuration file
209 reader "classes" (I can definitely see something reading a
210 configuration file in XML format, for example), called _CONF_*,
211 or "the configuration storage API"...
213 The new configuration file reading functions are:
215 NCONF_new, NCONF_free, NCONF_load, NCONF_load_fp, NCONF_load_bio,
216 NCONF_get_section, NCONF_get_string, NCONF_get_numbre
218 NCONF_default, NCONF_WIN32
220 NCONF_dump_fp, NCONF_dump_bio
222 NCONF_default and NCONF_WIN32 are method (or "class") choosers,
223 NCONF_new creates a new CONF object. This works in the same way
224 as other interfaces in OpenSSL, like the BIO interface.
225 NCONF_dump_* dump the internal storage of the configuration file,
226 which is useful for debugging. All other functions take the same
227 arguments as the old CONF_* functions wth the exception of the
228 first that must be a `CONF *' instead of a `LHASH *'.
230 To make it easer to use the new classes with the old CONF_* functions,
231 the function CONF_set_default_method is provided.
234 *) Add '-tls1' option to 'openssl ciphers', which was already
235 mentioned in the documentation but had not been implemented.
236 (This option is not yet really useful because even the additional
237 experimental TLS 1.0 ciphers are currently treated as SSL 3.0 ciphers.)
240 *) Initial DSO code added into libcrypto for letting OpenSSL (and
241 OpenSSL-based applications) load shared libraries and bind to
242 them in a portable way.
243 [Geoff Thorpe, with contributions from Richard Levitte]
245 Changes between 0.9.5 and 0.9.5a [1 Apr 2000]
247 *) Make sure _lrotl and _lrotr are only used with MSVC.
249 *) Use lock CRYPTO_LOCK_RAND correctly in ssleay_rand_status
250 (the default implementation of RAND_status).
252 *) Rename openssl x509 option '-crlext', which was added in 0.9.5,
253 to '-clrext' (= clear extensions), as intended and documented.
254 [Bodo Moeller; inconsistency pointed out by Michael Attili
257 *) Fix for HMAC. It wasn't zeroing the rest of the block if the key length
258 was larger than the MD block size.
259 [Steve Henson, pointed out by Yost William <YostW@tce.com>]
261 *) Modernise PKCS12_parse() so it uses STACK_OF(X509) for its ca argument
262 fix a leak when the ca argument was passed as NULL. Stop X509_PUBKEY_set()
263 using the passed key: if the passed key was a private key the result
264 of X509_print(), for example, would be to print out all the private key
268 *) des_quad_cksum() byte order bug fix.
269 [Ulf Möller, using the problem description in krb4-0.9.7, where
270 the solution is attributed to Derrick J Brashear <shadow@DEMENTIA.ORG>]
272 *) Fix so V_ASN1_APP_CHOOSE works again: however its use is strongly
274 [Steve Henson, pointed out by Brian Korver <briank@cs.stanford.edu>]
276 *) For easily testing in shell scripts whether some command
277 'openssl XXX' exists, the new pseudo-command 'openssl no-XXX'
278 returns with exit code 0 iff no command of the given name is available.
279 'no-XXX' is printed in this case, 'XXX' otherwise. In both cases,
280 the output goes to stdout and nothing is printed to stderr.
281 Additional arguments are always ignored.
283 Since for each cipher there is a command of the same name,
284 the 'no-cipher' compilation switches can be tested this way.
286 ('openssl no-XXX' is not able to detect pseudo-commands such
287 as 'quit', 'list-XXX-commands', or 'no-XXX' itself.)
290 *) Update test suite so that 'make test' succeeds in 'no-rsa' configuration.
293 *) For SSL_[CTX_]set_tmp_dh, don't create a DH key if SSL_OP_SINGLE_DH_USE
294 is set; it will be thrown away anyway because each handshake creates
296 ssl_cert_dup, which is used by SSL_new, now copies DH keys in addition
297 to parameters -- in previous versions (since OpenSSL 0.9.3) the
298 'default key' from SSL_CTX_set_tmp_dh would always be lost, meanining
299 you effectivly got SSL_OP_SINGLE_DH_USE when using this macro.
302 *) New s_client option -ign_eof: EOF at stdin is ignored, and
303 'Q' and 'R' lose their special meanings (quit/renegotiate).
304 This is part of what -quiet does; unlike -quiet, -ign_eof
305 does not suppress any output.
308 *) Add compatibility options to the purpose and trust code. The
309 purpose X509_PURPOSE_ANY is "any purpose" which automatically
310 accepts a certificate or CA, this was the previous behaviour,
311 with all the associated security issues.
313 X509_TRUST_COMPAT is the old trust behaviour: only and
314 automatically trust self signed roots in certificate store. A
315 new trust setting X509_TRUST_DEFAULT is used to specify that
316 a purpose has no associated trust setting and it should instead
317 use the value in the default purpose.
320 *) Fix the PKCS#8 DSA private key code so it decodes keys again
321 and fix a memory leak.
324 *) In util/mkerr.pl (which implements 'make errors'), preserve
325 reason strings from the previous version of the .c file, as
326 the default to have only downcase letters (and digits) in
327 automatically generated reasons codes is not always appropriate.
330 *) In ERR_load_ERR_strings(), build an ERR_LIB_SYS error reason table
331 using strerror. Previously, ERR_reason_error_string() returned
332 library names as reason strings for SYSerr; but SYSerr is a special
333 case where small numbers are errno values, not library numbers.
336 *) Add '-dsaparam' option to 'openssl dhparam' application. This
337 converts DSA parameters into DH parameters. (When creating parameters,
338 DSA_generate_parameters is used.)
341 *) Include 'length' (recommended exponent length) in C code generated
342 by 'openssl dhparam -C'.
345 *) The second argument to set_label in perlasm was already being used
346 so couldn't be used as a "file scope" flag. Moved to third argument
350 *) In PEM_ASN1_write_bio and some other functions, use RAND_pseudo_bytes
351 instead of RAND_bytes for encryption IVs and salts.
354 *) Include RAND_status() into RAND_METHOD instead of implementing
355 it only for md_rand.c Otherwise replacing the PRNG by calling
356 RAND_set_rand_method would be impossible.
359 *) Don't let DSA_generate_key() enter an infinite loop if the random
360 number generation fails.
363 *) New 'rand' application for creating pseudo-random output.
366 *) Added configuration support for Linux/IA64
367 [Rolf Haberrecker <rolf@suse.de>]
369 *) Assembler module support for Mingw32.
372 *) Shared library support for HPUX (in shlib/).
373 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE> and Anonymous]
375 *) Shared library support for Solaris gcc.
376 [Lutz Behnke <behnke@trustcenter.de>]
378 Changes between 0.9.4 and 0.9.5 [28 Feb 2000]
380 *) PKCS7_encrypt() was adding text MIME headers twice because they
381 were added manually and by SMIME_crlf_copy().
384 *) In bntest.c don't call BN_rand with zero bits argument.
385 [Steve Henson, pointed out by Andrew W. Gray <agray@iconsinc.com>]
387 *) BN_mul bugfix: In bn_mul_part_recursion() only the a>a[n] && b>b[n]
388 case was implemented. This caused BN_div_recp() to fail occasionally.
391 *) Add an optional second argument to the set_label() in the perl
392 assembly language builder. If this argument exists and is set
393 to 1 it signals that the assembler should use a symbol whose
394 scope is the entire file, not just the current function. This
395 is needed with MASM which uses the format label:: for this scope.
396 [Steve Henson, pointed out by Peter Runestig <peter@runestig.com>]
398 *) Change the ASN1 types so they are typedefs by default. Before
399 almost all types were #define'd to ASN1_STRING which was causing
400 STACK_OF() problems: you couldn't declare STACK_OF(ASN1_UTF8STRING)
404 *) Change names of new functions to the new get1/get0 naming
405 convention: After 'get1', the caller owns a reference count
406 and has to call ..._free; 'get0' returns a pointer to some
407 data structure without incrementing reference counters.
408 (Some of the existing 'get' functions increment a reference
409 counter, some don't.)
410 Similarly, 'set1' and 'add1' functions increase reference
411 counters or duplicate objects.
414 *) Allow for the possibility of temp RSA key generation failure:
415 the code used to assume it always worked and crashed on failure.
418 *) Fix potential buffer overrun problem in BIO_printf().
419 [Ulf Möller, using public domain code by Patrick Powell; problem
420 pointed out by David Sacerdote <das33@cornell.edu>]
422 *) Support EGD <http://www.lothar.com/tech/crypto/>. New functions
423 RAND_egd() and RAND_status(). In the command line application,
424 the EGD socket can be specified like a seed file using RANDFILE
428 *) Allow the string CERTIFICATE to be tolerated in PKCS#7 structures.
429 Some CAs (e.g. Verisign) distribute certificates in this form.
432 *) Remove the SSL_ALLOW_ADH compile option and set the default cipher
433 list to exclude them. This means that no special compilation option
434 is needed to use anonymous DH: it just needs to be included in the
438 *) Change the EVP_MD_CTX_type macro so its meaning consistent with
439 EVP_MD_type. The old functionality is available in a new macro called
440 EVP_MD_md(). Change code that uses it and update docs.
443 *) ..._ctrl functions now have corresponding ..._callback_ctrl functions
444 where the 'void *' argument is replaced by a function pointer argument.
445 Previously 'void *' was abused to point to functions, which works on
446 many platforms, but is not correct. As these functions are usually
447 called by macros defined in OpenSSL header files, most source code
448 should work without changes.
451 *) <openssl/opensslconf.h> (which is created by Configure) now contains
452 sections with information on -D... compiler switches used for
453 compiling the library so that applications can see them. To enable
454 one of these sections, a pre-processor symbol OPENSSL_..._DEFINES
455 must be defined. E.g.,
456 #define OPENSSL_ALGORITHM_DEFINES
457 #include <openssl/opensslconf.h>
458 defines all pertinent NO_<algo> symbols, such as NO_IDEA, NO_RSA, etc.
459 [Richard Levitte, Ulf and Bodo Möller]
461 *) Bugfix: Tolerate fragmentation and interleaving in the SSL 3/TLS
465 *) Change the 'other' type in certificate aux info to a STACK_OF
466 X509_ALGOR. Although not an AlgorithmIdentifier as such it has
467 the required ASN1 format: arbitrary types determined by an OID.
470 *) Add some PEM_write_X509_REQ_NEW() functions and a command line
471 argument to 'req'. This is not because the function is newer or
472 better than others it just uses the work 'NEW' in the certificate
473 request header lines. Some software needs this.
476 *) Reorganise password command line arguments: now passwords can be
477 obtained from various sources. Delete the PEM_cb function and make
478 it the default behaviour: i.e. if the callback is NULL and the
479 usrdata argument is not NULL interpret it as a null terminated pass
480 phrase. If usrdata and the callback are NULL then the pass phrase
481 is prompted for as usual.
484 *) Add support for the Compaq Atalla crypto accelerator. If it is installed,
485 the support is automatically enabled. The resulting binaries will
486 autodetect the card and use it if present.
487 [Ben Laurie and Compaq Inc.]
489 *) Work around for Netscape hang bug. This sends certificate request
490 and server done in one record. Since this is perfectly legal in the
491 SSL/TLS protocol it isn't a "bug" option and is on by default. See
492 the bugs/SSLv3 entry for more info.
495 *) HP-UX tune-up: new unified configs, HP C compiler bug workaround.
498 *) Add -rand argument to smime and pkcs12 applications and read/write
502 *) New 'passwd' tool for crypt(3) and apr1 password hashes.
505 *) Add command line password options to the remaining applications.
508 *) Bug fix for BN_div_recp() for numerators with an even number of
512 *) More tests in bntest.c, and changed test_bn output.
515 *) ./config recognizes MacOS X now.
518 *) Bug fix for BN_div() when the first words of num and divsor are
519 equal (it gave wrong results if (rem=(n1-q*d0)&BN_MASK2) < d0).
522 *) Add support for various broken PKCS#8 formats, and command line
523 options to produce them.
526 *) New functions BN_CTX_start(), BN_CTX_get() and BT_CTX_end() to
527 get temporary BIGNUMs from a BN_CTX.
530 *) Correct return values in BN_mod_exp_mont() and BN_mod_exp2_mont()
534 *) Change the SSLeay_add_all_*() functions to OpenSSL_add_all_*() and
535 include a #define from the old name to the new. The original intent
536 was that statically linked binaries could for example just call
537 SSLeay_add_all_ciphers() to just add ciphers to the table and not
538 link with digests. This never worked becayse SSLeay_add_all_digests()
539 and SSLeay_add_all_ciphers() were in the same source file so calling
540 one would link with the other. They are now in separate source files.
543 *) Add a new -notext option to 'ca' and a -pubkey option to 'spkac'.
546 *) Use a less unusual form of the Miller-Rabin primality test (it used
547 a binary algorithm for exponentiation integrated into the Miller-Rabin
548 loop, our standard modexp algorithms are faster).
551 *) Support for the EBCDIC character set completed.
552 [Martin Kraemer <Martin.Kraemer@Mch.SNI.De>]
554 *) Source code cleanups: use const where appropriate, eliminate casts,
555 use void * instead of char * in lhash.
558 *) Bugfix: ssl3_send_server_key_exchange was not restartable
559 (the state was not changed to SSL3_ST_SW_KEY_EXCH_B, and because of
560 this the server could overwrite ephemeral keys that the client
564 *) Turn DSA_is_prime into a macro that calls BN_is_prime,
565 using 50 iterations of the Rabin-Miller test.
567 DSA_generate_parameters now uses BN_is_prime_fasttest (with 50
568 iterations of the Rabin-Miller test as required by the appendix
569 to FIPS PUB 186[-1]) instead of DSA_is_prime.
570 As BN_is_prime_fasttest includes trial division, DSA parameter
571 generation becomes much faster.
573 This implies a change for the callback functions in DSA_is_prime
574 and DSA_generate_parameters: The callback function is called once
575 for each positive witness in the Rabin-Miller test, not just
576 occasionally in the inner loop; and the parameters to the
577 callback function now provide an iteration count for the outer
578 loop rather than for the current invocation of the inner loop.
579 DSA_generate_parameters additionally can call the callback
580 function with an 'iteration count' of -1, meaning that a
581 candidate has passed the trial division test (when q is generated
582 from an application-provided seed, trial division is skipped).
585 *) New function BN_is_prime_fasttest that optionally does trial
586 division before starting the Rabin-Miller test and has
587 an additional BN_CTX * argument (whereas BN_is_prime always
588 has to allocate at least one BN_CTX).
589 'callback(1, -1, cb_arg)' is called when a number has passed the
590 trial division stage.
593 *) Fix for bug in CRL encoding. The validity dates weren't being handled
597 *) New -pkcs12 option to CA.pl script to write out a PKCS#12 file.
600 *) New function BN_pseudo_rand().
603 *) Clean up BN_mod_mul_montgomery(): replace the broken (and unreadable)
604 bignum version of BN_from_montgomery() with the working code from
605 SSLeay 0.9.0 (the word based version is faster anyway), and clean up
609 *) Avoid a race condition in s2_clnt.c (function get_server_hello) that
610 made it impossible to use the same SSL_SESSION data structure in
611 SSL2 clients in multiple threads.
614 *) The return value of RAND_load_file() no longer counts bytes obtained
615 by stat(). RAND_load_file(..., -1) is new and uses the complete file
616 to seed the PRNG (previously an explicit byte count was required).
617 [Ulf Möller, Bodo Möller]
619 *) Clean up CRYPTO_EX_DATA functions, some of these didn't have prototypes
620 used (char *) instead of (void *) and had casts all over the place.
623 *) Make BN_generate_prime() return NULL on error if ret!=NULL.
626 *) Retain source code compatibility for BN_prime_checks macro:
627 BN_is_prime(..., BN_prime_checks, ...) now uses
628 BN_prime_checks_for_size to determine the appropriate number of
629 Rabin-Miller iterations.
632 *) Diffie-Hellman uses "safe" primes: DH_check() return code renamed to
633 DH_CHECK_P_NOT_SAFE_PRIME.
634 (Check if this is true? OpenPGP calls them "strong".)
637 *) Merge the functionality of "dh" and "gendh" programs into a new program
638 "dhparam". The old programs are retained for now but will handle DH keys
639 (instead of parameters) in future.
642 *) Make the ciphers, s_server and s_client programs check the return values
643 when a new cipher list is set.
646 *) Enhance the SSL/TLS cipher mechanism to correctly handle the TLS 56bit
647 ciphers. Before when the 56bit ciphers were enabled the sorting was
650 The syntax for the cipher sorting has been extended to support sorting by
651 cipher-strength (using the strength_bits hard coded in the tables).
652 The new command is "@STRENGTH" (see also doc/apps/ciphers.pod).
654 Fix a bug in the cipher-command parser: when supplying a cipher command
655 string with an "undefined" symbol (neither command nor alphanumeric
656 [A-Za-z0-9], ssl_set_cipher_list used to hang in an endless loop. Now
659 Due to the strength-sorting extension, the code of the
660 ssl_create_cipher_list() function was completely rearranged. I hope that
661 the readability was also increased :-)
662 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
664 *) Minor change to 'x509' utility. The -CAcreateserial option now uses 1
665 for the first serial number and places 2 in the serial number file. This
666 avoids problems when the root CA is created with serial number zero and
667 the first user certificate has the same issuer name and serial number
671 *) Fixes to X509_ATTRIBUTE utilities, change the 'req' program so it uses
672 the new code. Add documentation for this stuff.
675 *) Changes to X509_ATTRIBUTE utilities. These have been renamed from
676 X509_*() to X509at_*() on the grounds that they don't handle X509
677 structures and behave in an analagous way to the X509v3 functions:
678 they shouldn't be called directly but wrapper functions should be used
681 So we also now have some wrapper functions that call the X509at functions
682 when passed certificate requests. (TO DO: similar things can be done with
683 PKCS#7 signed and unsigned attributes, PKCS#12 attributes and a few other
684 things. Some of these need some d2i or i2d and print functionality
685 because they handle more complex structures.)
688 *) Add missing #ifndefs that caused missing symbols when building libssl
689 as a shared library without RSA. Use #ifndef NO_SSL2 instead of
691 [Kris Kennaway <kris@hub.freebsd.org>, modified by Ulf Möller]
693 *) Precautions against using the PRNG uninitialized: RAND_bytes() now
694 has a return value which indicates the quality of the random data
695 (1 = ok, 0 = not seeded). Also an error is recorded on the thread's
696 error queue. New function RAND_pseudo_bytes() generates output that is
697 guaranteed to be unique but not unpredictable. RAND_add is like
698 RAND_seed, but takes an extra argument for an entropy estimate
699 (RAND_seed always assumes full entropy).
702 *) Do more iterations of Rabin-Miller probable prime test (specifically,
703 3 for 1024-bit primes, 6 for 512-bit primes, 12 for 256-bit primes
704 instead of only 2 for all lengths; see BN_prime_checks_for_size definition
705 in crypto/bn/bn_prime.c for the complete table). This guarantees a
706 false-positive rate of at most 2^-80 for random input.
709 *) Rewrite ssl3_read_n (ssl/s3_pkt.c) avoiding a couple of bugs.
712 *) New function X509_CTX_rget_chain() (renamed to X509_CTX_get1_chain
713 in the 0.9.5 release), this returns the chain
714 from an X509_CTX structure with a dup of the stack and all
715 the X509 reference counts upped: so the stack will exist
716 after X509_CTX_cleanup() has been called. Modify pkcs12.c
719 Also make SSL_SESSION_print() print out the verify return
723 *) Add manpage for the pkcs12 command. Also change the default
724 behaviour so MAC iteration counts are used unless the new
725 -nomaciter option is used. This improves file security and
726 only older versions of MSIE (4.0 for example) need it.
729 *) Honor the no-xxx Configure options when creating .DEF files.
732 *) Add PKCS#10 attributes to field table: challengePassword,
733 unstructuredName and unstructuredAddress. These are taken from
734 draft PKCS#9 v2.0 but are compatible with v1.2 provided no
735 international characters are used.
737 More changes to X509_ATTRIBUTE code: allow the setting of types
738 based on strings. Remove the 'loc' parameter when adding
739 attributes because these will be a SET OF encoding which is sorted
743 *) Initial changes to the 'req' utility to allow request generation
744 automation. This will allow an application to just generate a template
745 file containing all the field values and have req construct the
748 Initial support for X509_ATTRIBUTE handling. Stacks of these are
749 used all over the place including certificate requests and PKCS#7
750 structures. They are currently handled manually where necessary with
751 some primitive wrappers for PKCS#7. The new functions behave in a
752 manner analogous to the X509 extension functions: they allow
753 attributes to be looked up by NID and added.
755 Later something similar to the X509V3 code would be desirable to
756 automatically handle the encoding, decoding and printing of the
757 more complex types. The string types like challengePassword can
758 be handled by the string table functions.
760 Also modified the multi byte string table handling. Now there is
761 a 'global mask' which masks out certain types. The table itself
762 can use the flag STABLE_NO_MASK to ignore the mask setting: this
763 is useful when for example there is only one permissible type
764 (as in countryName) and using the mask might result in no valid
768 *) Clean up 'Finished' handling, and add functions SSL_get_finished and
769 SSL_get_peer_finished to allow applications to obtain the latest
770 Finished messages sent to the peer or expected from the peer,
771 respectively. (SSL_get_peer_finished is usually the Finished message
772 actually received from the peer, otherwise the protocol will be aborted.)
774 As the Finished message are message digests of the complete handshake
775 (with a total of 192 bits for TLS 1.0 and more for SSL 3.0), they can
776 be used for external authentication procedures when the authentication
777 provided by SSL/TLS is not desired or is not enough.
780 *) Enhanced support for Alpha Linux is added. Now ./config checks if
781 the host supports BWX extension and if Compaq C is present on the
782 $PATH. Just exploiting of the BWX extension results in 20-30%
783 performance kick for some algorithms, e.g. DES and RC4 to mention
784 a couple. Compaq C in turn generates ~20% faster code for MD5 and
788 *) Add support for MS "fast SGC". This is arguably a violation of the
789 SSL3/TLS protocol. Netscape SGC does two handshakes: the first with
790 weak crypto and after checking the certificate is SGC a second one
791 with strong crypto. MS SGC stops the first handshake after receiving
792 the server certificate message and sends a second client hello. Since
793 a server will typically do all the time consuming operations before
794 expecting any further messages from the client (server key exchange
795 is the most expensive) there is little difference between the two.
797 To get OpenSSL to support MS SGC we have to permit a second client
798 hello message after we have sent server done. In addition we have to
799 reset the MAC if we do get this second client hello.
802 *) Add a function 'd2i_AutoPrivateKey()' this will automatically decide
803 if a DER encoded private key is RSA or DSA traditional format. Changed
804 d2i_PrivateKey_bio() to use it. This is only needed for the "traditional"
805 format DER encoded private key. Newer code should use PKCS#8 format which
806 has the key type encoded in the ASN1 structure. Added DER private key
807 support to pkcs8 application.
810 *) SSL 3/TLS 1 servers now don't request certificates when an anonymous
811 ciphersuites has been selected (as required by the SSL 3/TLS 1
812 specifications). Exception: When SSL_VERIFY_FAIL_IF_NO_PEER_CERT
813 is set, we interpret this as a request to violate the specification
814 (the worst that can happen is a handshake failure, and 'correct'
815 behaviour would result in a handshake failure anyway).
818 *) In SSL_CTX_add_session, take into account that there might be multiple
819 SSL_SESSION structures with the same session ID (e.g. when two threads
820 concurrently obtain them from an external cache).
821 The internal cache can handle only one SSL_SESSION with a given ID,
822 so if there's a conflict, we now throw out the old one to achieve
826 *) Add OIDs for idea and blowfish in CBC mode. This will allow both
827 to be used in PKCS#5 v2.0 and S/MIME. Also add checking to
828 some routines that use cipher OIDs: some ciphers do not have OIDs
829 defined and so they cannot be used for S/MIME and PKCS#5 v2.0 for
833 *) Simplify the trust setting structure and code. Now we just have
834 two sequences of OIDs for trusted and rejected settings. These will
835 typically have values the same as the extended key usage extension
836 and any application specific purposes.
838 The trust checking code now has a default behaviour: it will just
839 check for an object with the same NID as the passed id. Functions can
840 be provided to override either the default behaviour or the behaviour
841 for a given id. SSL client, server and email already have functions
842 in place for compatibility: they check the NID and also return "trusted"
843 if the certificate is self signed.
846 *) Add d2i,i2d bio/fp functions for PrivateKey: these convert the
847 traditional format into an EVP_PKEY structure.
850 *) Add a password callback function PEM_cb() which either prompts for
851 a password if usr_data is NULL or otherwise assumes it is a null
852 terminated password. Allow passwords to be passed on command line
853 environment or config files in a few more utilities.
856 *) Add a bunch of DER and PEM functions to handle PKCS#8 format private
857 keys. Add some short names for PKCS#8 PBE algorithms and allow them
858 to be specified on the command line for the pkcs8 and pkcs12 utilities.
859 Update documentation.
862 *) Support for ASN1 "NULL" type. This could be handled before by using
863 ASN1_TYPE but there wasn't any function that would try to read a NULL
864 and produce an error if it couldn't. For compatibility we also have
865 ASN1_NULL_new() and ASN1_NULL_free() functions but these are faked and
866 don't allocate anything because they don't need to.
869 *) Initial support for MacOS is now provided. Examine INSTALL.MacOS
871 [Andy Polyakov, Roy Woods <roy@centicsystems.ca>]
873 *) Rebuild of the memory allocation routines used by OpenSSL code and
874 possibly others as well. The purpose is to make an interface that
875 provide hooks so anyone can build a separate set of allocation and
876 deallocation routines to be used by OpenSSL, for example memory
877 pool implementations, or something else, which was previously hard
878 since Malloc(), Realloc() and Free() were defined as macros having
879 the values malloc, realloc and free, respectively (except for Win32
880 compilations). The same is provided for memory debugging code.
881 OpenSSL already comes with functionality to find memory leaks, but
882 this gives people a chance to debug other memory problems.
884 With these changes, a new set of functions and macros have appeared:
886 CRYPTO_set_mem_debug_functions() [F]
887 CRYPTO_get_mem_debug_functions() [F]
888 CRYPTO_dbg_set_options() [F]
889 CRYPTO_dbg_get_options() [F]
890 CRYPTO_malloc_debug_init() [M]
892 The memory debug functions are NULL by default, unless the library
893 is compiled with CRYPTO_MDEBUG or friends is defined. If someone
894 wants to debug memory anyway, CRYPTO_malloc_debug_init() (which
895 gives the standard debugging functions that come with OpenSSL) or
896 CRYPTO_set_mem_debug_functions() (tells OpenSSL to use functions
897 provided by the library user) must be used. When the standard
898 debugging functions are used, CRYPTO_dbg_set_options can be used to
899 request additional information:
900 CRYPTO_dbg_set_options(V_CYRPTO_MDEBUG_xxx) corresponds to setting
901 the CRYPTO_MDEBUG_xxx macro when compiling the library.
903 Also, things like CRYPTO_set_mem_functions will always give the
904 expected result (the new set of functions is used for allocation
905 and deallocation) at all times, regardless of platform and compiler
908 To finish it up, some functions that were never use in any other
909 way than through macros have a new API and new semantic:
915 All macros of value have retained their old syntax.
916 [Richard Levitte and Bodo Moeller]
918 *) Some S/MIME fixes. The OID for SMIMECapabilities was wrong, the
919 ordering of SMIMECapabilities wasn't in "strength order" and there
920 was a missing NULL in the AlgorithmIdentifier for the SHA1 signature
924 *) Some ASN1 types with illegal zero length encoding (INTEGER,
925 ENUMERATED and OBJECT IDENTIFIER) choked the ASN1 routines.
926 [Frans Heymans <fheymans@isaserver.be>, modified by Steve Henson]
928 *) Merge in my S/MIME library for OpenSSL. This provides a simple
929 S/MIME API on top of the PKCS#7 code, a MIME parser (with enough
930 functionality to handle multipart/signed properly) and a utility
931 called 'smime' to call all this stuff. This is based on code I
932 originally wrote for Celo who have kindly allowed it to be
936 *) Add variants des_set_key_checked and des_set_key_unchecked of
937 des_set_key (aka des_key_sched). Global variable des_check_key
938 decides which of these is called by des_set_key; this way
939 des_check_key behaves as it always did, but applications and
940 the library itself, which was buggy for des_check_key == 1,
941 have a cleaner way to pick the version they need.
944 *) New function PKCS12_newpass() which changes the password of a
948 *) Modify X509_TRUST and X509_PURPOSE so it also uses a static and
949 dynamic mix. In both cases the ids can be used as an index into the
950 table. Also modified the X509_TRUST_add() and X509_PURPOSE_add()
951 functions so they accept a list of the field values and the
952 application doesn't need to directly manipulate the X509_TRUST
956 *) Modify the ASN1_STRING_TABLE stuff so it also uses bsearch and doesn't
960 *) Modify the way the V3 extension code looks up extensions. This now
961 works in a similar way to the object code: we have some "standard"
962 extensions in a static table which is searched with OBJ_bsearch()
963 and the application can add dynamic ones if needed. The file
964 crypto/x509v3/ext_dat.h now has the info: this file needs to be
965 updated whenever a new extension is added to the core code and kept
966 in ext_nid order. There is a simple program 'tabtest.c' which checks
967 this. New extensions are not added too often so this file can readily
968 be maintained manually.
970 There are two big advantages in doing things this way. The extensions
971 can be looked up immediately and no longer need to be "added" using
972 X509V3_add_standard_extensions(): this function now does nothing.
973 [Side note: I get *lots* of email saying the extension code doesn't
974 work because people forget to call this function]
975 Also no dynamic allocation is done unless new extensions are added:
976 so if we don't add custom extensions there is no need to call
977 X509V3_EXT_cleanup().
980 *) Modify enc utility's salting as follows: make salting the default. Add a
981 magic header, so unsalted files fail gracefully instead of just decrypting
982 to garbage. This is because not salting is a big security hole, so people
983 should be discouraged from doing it.
986 *) Fixes and enhancements to the 'x509' utility. It allowed a message
987 digest to be passed on the command line but it only used this
988 parameter when signing a certificate. Modified so all relevant
989 operations are affected by the digest parameter including the
990 -fingerprint and -x509toreq options. Also -x509toreq choked if a
991 DSA key was used because it didn't fix the digest.
994 *) Initial certificate chain verify code. Currently tests the untrusted
995 certificates for consistency with the verify purpose (which is set
996 when the X509_STORE_CTX structure is set up) and checks the pathlength.
998 There is a NO_CHAIN_VERIFY compilation option to keep the old behaviour:
999 this is because it will reject chains with invalid extensions whereas
1000 every previous version of OpenSSL and SSLeay made no checks at all.
1002 Trust code: checks the root CA for the relevant trust settings. Trust
1003 settings have an initial value consistent with the verify purpose: e.g.
1004 if the verify purpose is for SSL client use it expects the CA to be
1005 trusted for SSL client use. However the default value can be changed to
1006 permit custom trust settings: one example of this would be to only trust
1007 certificates from a specific "secure" set of CAs.
1009 Also added X509_STORE_CTX_new() and X509_STORE_CTX_free() functions
1010 which should be used for version portability: especially since the
1011 verify structure is likely to change more often now.
1013 SSL integration. Add purpose and trust to SSL_CTX and SSL and functions
1014 to set them. If not set then assume SSL clients will verify SSL servers
1017 Two new options to the verify program: -untrusted allows a set of
1018 untrusted certificates to be passed in and -purpose which sets the
1019 intended purpose of the certificate. If a purpose is set then the
1020 new chain verify code is used to check extension consistency.
1023 *) Support for the authority information access extension.
1026 *) Modify RSA and DSA PEM read routines to transparently handle
1027 PKCS#8 format private keys. New *_PUBKEY_* functions that handle
1028 public keys in a format compatible with certificate
1029 SubjectPublicKeyInfo structures. Unfortunately there were already
1030 functions called *_PublicKey_* which used various odd formats so
1031 these are retained for compatibility: however the DSA variants were
1032 never in a public release so they have been deleted. Changed dsa/rsa
1033 utilities to handle the new format: note no releases ever handled public
1034 keys so we should be OK.
1036 The primary motivation for this change is to avoid the same fiasco
1037 that dogs private keys: there are several incompatible private key
1038 formats some of which are standard and some OpenSSL specific and
1039 require various evil hacks to allow partial transparent handling and
1040 even then it doesn't work with DER formats. Given the option anything
1041 other than PKCS#8 should be dumped: but the other formats have to
1042 stay in the name of compatibility.
1044 With public keys and the benefit of hindsight one standard format
1045 is used which works with EVP_PKEY, RSA or DSA structures: though
1046 it clearly returns an error if you try to read the wrong kind of key.
1048 Added a -pubkey option to the 'x509' utility to output the public key.
1049 Also rename the EVP_PKEY_get_*() to EVP_PKEY_rget_*()
1050 (renamed to EVP_PKEY_get1_*() in the OpenSSL 0.9.5 release) and add
1051 EVP_PKEY_rset_*() functions (renamed to EVP_PKEY_set1_*())
1052 that do the same as the EVP_PKEY_assign_*() except they up the
1053 reference count of the added key (they don't "swallow" the
1057 *) Fixes to crypto/x509/by_file.c the code to read in certificates and
1058 CRLs would fail if the file contained no certificates or no CRLs:
1059 added a new function to read in both types and return the number
1060 read: this means that if none are read it will be an error. The
1061 DER versions of the certificate and CRL reader would always fail
1062 because it isn't possible to mix certificates and CRLs in DER format
1063 without choking one or the other routine. Changed this to just read
1064 a certificate: this is the best we can do. Also modified the code
1065 in apps/verify.c to take notice of return codes: it was previously
1066 attempting to read in certificates from NULL pointers and ignoring
1067 any errors: this is one reason why the cert and CRL reader seemed
1068 to work. It doesn't check return codes from the default certificate
1069 routines: these may well fail if the certificates aren't installed.
1072 *) Code to support otherName option in GeneralName.
1075 *) First update to verify code. Change the verify utility
1076 so it warns if it is passed a self signed certificate:
1077 for consistency with the normal behaviour. X509_verify
1078 has been modified to it will now verify a self signed
1079 certificate if *exactly* the same certificate appears
1080 in the store: it was previously impossible to trust a
1081 single self signed certificate. This means that:
1082 openssl verify ss.pem
1083 now gives a warning about a self signed certificate but
1084 openssl verify -CAfile ss.pem ss.pem
1088 *) For servers, store verify_result in SSL_SESSION data structure
1089 (and add it to external session representation).
1090 This is needed when client certificate verifications fails,
1091 but an application-provided verification callback (set by
1092 SSL_CTX_set_cert_verify_callback) allows accepting the session
1093 anyway (i.e. leaves x509_store_ctx->error != X509_V_OK
1094 but returns 1): When the session is reused, we have to set
1095 ssl->verify_result to the appropriate error code to avoid
1097 [Bodo Moeller, problem pointed out by Lutz Jaenicke]
1099 *) Fix a bug in the new PKCS#7 code: it didn't consider the
1100 case in PKCS7_dataInit() where the signed PKCS7 structure
1101 didn't contain any existing data because it was being created.
1102 [Po-Cheng Chen <pocheng@nst.com.tw>, slightly modified by Steve Henson]
1104 *) Add a salt to the key derivation routines in enc.c. This
1105 forms the first 8 bytes of the encrypted file. Also add a
1106 -S option to allow a salt to be input on the command line.
1109 *) New function X509_cmp(). Oddly enough there wasn't a function
1110 to compare two certificates. We do this by working out the SHA1
1111 hash and comparing that. X509_cmp() will be needed by the trust
1115 *) SSL_get1_session() is like SSL_get_session(), but increments
1116 the reference count in the SSL_SESSION returned.
1117 [Geoff Thorpe <geoff@eu.c2.net>]
1119 *) Fix for 'req': it was adding a null to request attributes.
1120 Also change the X509_LOOKUP and X509_INFO code to handle
1121 certificate auxiliary information.
1124 *) Add support for 40 and 64 bit RC2 and RC4 algorithms: document
1128 *) Add the possibility to add extra information to the memory leak
1129 detecting output, to form tracebacks, showing from where each
1130 allocation was originated: CRYPTO_push_info("constant string") adds
1131 the string plus current file name and line number to a per-thread
1132 stack, CRYPTO_pop_info() does the obvious, CRYPTO_remove_all_info()
1133 is like calling CYRPTO_pop_info() until the stack is empty.
1134 Also updated memory leak detection code to be multi-thread-safe.
1137 *) Add options -text and -noout to pkcs7 utility and delete the
1138 encryption options which never did anything. Update docs.
1141 *) Add options to some of the utilities to allow the pass phrase
1142 to be included on either the command line (not recommended on
1143 OSes like Unix) or read from the environment. Update the
1144 manpages and fix a few bugs.
1147 *) Add a few manpages for some of the openssl commands.
1150 *) Fix the -revoke option in ca. It was freeing up memory twice,
1151 leaking and not finding already revoked certificates.
1154 *) Extensive changes to support certificate auxiliary information.
1155 This involves the use of X509_CERT_AUX structure and X509_AUX
1156 functions. An X509_AUX function such as PEM_read_X509_AUX()
1157 can still read in a certificate file in the usual way but it
1158 will also read in any additional "auxiliary information". By
1159 doing things this way a fair degree of compatibility can be
1160 retained: existing certificates can have this information added
1161 using the new 'x509' options.
1163 Current auxiliary information includes an "alias" and some trust
1164 settings. The trust settings will ultimately be used in enhanced
1165 certificate chain verification routines: currently a certificate
1166 can only be trusted if it is self signed and then it is trusted
1170 *) Fix assembler for Alpha (tested only on DEC OSF not Linux or *BSD).
1171 The problem was that one of the replacement routines had not been working
1172 since SSLeay releases. For now the offending routine has been replaced
1173 with non-optimised assembler. Even so, this now gives around 95%
1174 performance improvement for 1024 bit RSA signs.
1177 *) Hack to fix PKCS#7 decryption when used with some unorthodox RC2
1178 handling. Most clients have the effective key size in bits equal to
1179 the key length in bits: so a 40 bit RC2 key uses a 40 bit (5 byte) key.
1180 A few however don't do this and instead use the size of the decrypted key
1181 to determine the RC2 key length and the AlgorithmIdentifier to determine
1182 the effective key length. In this case the effective key length can still
1183 be 40 bits but the key length can be 168 bits for example. This is fixed
1184 by manually forcing an RC2 key into the EVP_PKEY structure because the
1185 EVP code can't currently handle unusual RC2 key sizes: it always assumes
1186 the key length and effective key length are equal.
1189 *) Add a bunch of functions that should simplify the creation of
1190 X509_NAME structures. Now you should be able to do:
1191 X509_NAME_add_entry_by_txt(nm, "CN", MBSTRING_ASC, "Steve", -1, -1, 0);
1192 and have it automatically work out the correct field type and fill in
1193 the structures. The more adventurous can try:
1194 X509_NAME_add_entry_by_txt(nm, field, MBSTRING_UTF8, str, -1, -1, 0);
1195 and it will (hopefully) work out the correct multibyte encoding.
1198 *) Change the 'req' utility to use the new field handling and multibyte
1199 copy routines. Before the DN field creation was handled in an ad hoc
1200 way in req, ca, and x509 which was rather broken and didn't support
1201 BMPStrings or UTF8Strings. Since some software doesn't implement
1202 BMPStrings or UTF8Strings yet, they can be enabled using the config file
1203 using the dirstring_type option. See the new comment in the default
1204 openssl.cnf for more info.
1207 *) Make crypto/rand/md_rand.c more robust:
1208 - Assure unique random numbers after fork().
1209 - Make sure that concurrent threads access the global counter and
1210 md serializably so that we never lose entropy in them
1211 or use exactly the same state in multiple threads.
1212 Access to the large state is not always serializable because
1213 the additional locking could be a performance killer, and
1214 md should be large enough anyway.
1217 *) New file apps/app_rand.c with commonly needed functionality
1218 for handling the random seed file.
1220 Use the random seed file in some applications that previously did not:
1222 dsaparam -genkey (which also ignored its '-rand' option),
1225 x509 (when signing).
1226 Except on systems with /dev/urandom, it is crucial to have a random
1227 seed file at least for key creation, DSA signing, and for DH exchanges;
1228 for RSA signatures we could do without one.
1230 gendh and gendsa (unlike genrsa) used to read only the first byte
1231 of each file listed in the '-rand' option. The function as previously
1232 found in genrsa is now in app_rand.c and is used by all programs
1233 that support '-rand'.
1236 *) In RAND_write_file, use mode 0600 for creating files;
1237 don't just chmod when it may be too late.
1240 *) Report an error from X509_STORE_load_locations
1241 when X509_LOOKUP_load_file or X509_LOOKUP_add_dir failed.
1244 *) New function ASN1_mbstring_copy() this copies a string in either
1245 ASCII, Unicode, Universal (4 bytes per character) or UTF8 format
1246 into an ASN1_STRING type. A mask of permissible types is passed
1247 and it chooses the "minimal" type to use or an error if not type
1251 *) Add function equivalents to the various macros in asn1.h. The old
1252 macros are retained with an M_ prefix. Code inside the library can
1253 use the M_ macros. External code (including the openssl utility)
1254 should *NOT* in order to be "shared library friendly".
1257 *) Add various functions that can check a certificate's extensions
1258 to see if it usable for various purposes such as SSL client,
1259 server or S/MIME and CAs of these types. This is currently
1260 VERY EXPERIMENTAL but will ultimately be used for certificate chain
1261 verification. Also added a -purpose flag to x509 utility to
1262 print out all the purposes.
1265 *) Add a CRYPTO_EX_DATA to X509 certificate structure and associated
1269 *) New X509V3_{X509,CRL,REVOKED}_get_d2i() functions. These will search
1270 for, obtain and decode and extension and obtain its critical flag.
1271 This allows all the necessary extension code to be handled in a
1272 single function call.
1275 *) RC4 tune-up featuring 30-40% performance improvement on most RISC
1276 platforms. See crypto/rc4/rc4_enc.c for further details.
1279 *) New -noout option to asn1parse. This causes no output to be produced
1280 its main use is when combined with -strparse and -out to extract data
1281 from a file (which may not be in ASN.1 format).
1284 *) Fix for pkcs12 program. It was hashing an invalid certificate pointer
1285 when producing the local key id.
1286 [Richard Levitte <levitte@stacken.kth.se>]
1288 *) New option -dhparam in s_server. This allows a DH parameter file to be
1289 stated explicitly. If it is not stated then it tries the first server
1290 certificate file. The previous behaviour hard coded the filename
1294 *) Add -pubin and -pubout options to the rsa and dsa commands. These allow
1295 a public key to be input or output. For example:
1296 openssl rsa -in key.pem -pubout -out pubkey.pem
1297 Also added necessary DSA public key functions to handle this.
1300 *) Fix so PKCS7_dataVerify() doesn't crash if no certificates are contained
1301 in the message. This was handled by allowing
1302 X509_find_by_issuer_and_serial() to tolerate a NULL passed to it.
1303 [Steve Henson, reported by Sampo Kellomaki <sampo@mail.neuronio.pt>]
1305 *) Fix for bug in d2i_ASN1_bytes(): other ASN1 functions add an extra null
1306 to the end of the strings whereas this didn't. This would cause problems
1307 if strings read with d2i_ASN1_bytes() were later modified.
1308 [Steve Henson, reported by Arne Ansper <arne@ats.cyber.ee>]
1310 *) Fix for base64 decode bug. When a base64 bio reads only one line of
1311 data and it contains EOF it will end up returning an error. This is
1312 caused by input 46 bytes long. The cause is due to the way base64
1313 BIOs find the start of base64 encoded data. They do this by trying a
1314 trial decode on each line until they find one that works. When they
1315 do a flag is set and it starts again knowing it can pass all the
1316 data directly through the decoder. Unfortunately it doesn't reset
1317 the context it uses. This means that if EOF is reached an attempt
1318 is made to pass two EOFs through the context and this causes the
1319 resulting error. This can also cause other problems as well. As is
1320 usual with these problems it takes *ages* to find and the fix is
1321 trivial: move one line.
1322 [Steve Henson, reported by ian@uns.ns.ac.yu (Ivan Nejgebauer) ]
1324 *) Ugly workaround to get s_client and s_server working under Windows. The
1325 old code wouldn't work because it needed to select() on sockets and the
1326 tty (for keypresses and to see if data could be written). Win32 only
1327 supports select() on sockets so we select() with a 1s timeout on the
1328 sockets and then see if any characters are waiting to be read, if none
1329 are present then we retry, we also assume we can always write data to
1330 the tty. This isn't nice because the code then blocks until we've
1331 received a complete line of data and it is effectively polling the
1332 keyboard at 1s intervals: however it's quite a bit better than not
1333 working at all :-) A dedicated Windows application might handle this
1334 with an event loop for example.
1337 *) Enhance RSA_METHOD structure. Now there are two extra methods, rsa_sign
1338 and rsa_verify. When the RSA_FLAGS_SIGN_VER option is set these functions
1339 will be called when RSA_sign() and RSA_verify() are used. This is useful
1340 if rsa_pub_dec() and rsa_priv_enc() equivalents are not available.
1341 For this to work properly RSA_public_decrypt() and RSA_private_encrypt()
1342 should *not* be used: RSA_sign() and RSA_verify() must be used instead.
1343 This necessitated the support of an extra signature type NID_md5_sha1
1344 for SSL signatures and modifications to the SSL library to use it instead
1345 of calling RSA_public_decrypt() and RSA_private_encrypt().
1348 *) Add new -verify -CAfile and -CApath options to the crl program, these
1349 will lookup a CRL issuers certificate and verify the signature in a
1350 similar way to the verify program. Tidy up the crl program so it
1351 no longer accesses structures directly. Make the ASN1 CRL parsing a bit
1352 less strict. It will now permit CRL extensions even if it is not
1353 a V2 CRL: this will allow it to tolerate some broken CRLs.
1356 *) Initialize all non-automatic variables each time one of the openssl
1357 sub-programs is started (this is necessary as they may be started
1358 multiple times from the "OpenSSL>" prompt).
1359 [Lennart Bang, Bodo Moeller]
1361 *) Preliminary compilation option RSA_NULL which disables RSA crypto without
1362 removing all other RSA functionality (this is what NO_RSA does). This
1363 is so (for example) those in the US can disable those operations covered
1364 by the RSA patent while allowing storage and parsing of RSA keys and RSA
1368 *) Non-copying interface to BIO pairs.
1369 (still largely untested)
1372 *) New function ANS1_tag2str() to convert an ASN1 tag to a descriptive
1373 ASCII string. This was handled independently in various places before.
1376 *) New functions UTF8_getc() and UTF8_putc() that parse and generate
1377 UTF8 strings a character at a time.
1380 *) Use client_version from client hello to select the protocol
1381 (s23_srvr.c) and for RSA client key exchange verification
1382 (s3_srvr.c), as required by the SSL 3.0/TLS 1.0 specifications.
1385 *) Add various utility functions to handle SPKACs, these were previously
1386 handled by poking round in the structure internals. Added new function
1387 NETSCAPE_SPKI_print() to print out SPKAC and a new utility 'spkac' to
1388 print, verify and generate SPKACs. Based on an original idea from
1389 Massimiliano Pala <madwolf@comune.modena.it> but extensively modified.
1392 *) RIPEMD160 is operational on all platforms and is back in 'make test'.
1395 *) Allow the config file extension section to be overwritten on the
1396 command line. Based on an original idea from Massimiliano Pala
1397 <madwolf@comune.modena.it>. The new option is called -extensions
1398 and can be applied to ca, req and x509. Also -reqexts to override
1399 the request extensions in req and -crlexts to override the crl extensions
1403 *) Add new feature to the SPKAC handling in ca. Now you can include
1404 the same field multiple times by preceding it by "XXXX." for example:
1407 this is the same syntax as used in the req config file.
1410 *) Allow certificate extensions to be added to certificate requests. These
1411 are specified in a 'req_extensions' option of the req section of the
1412 config file. They can be printed out with the -text option to req but
1413 are otherwise ignored at present.
1416 *) Fix a horrible bug in enc_read() in crypto/evp/bio_enc.c: if the first
1417 data read consists of only the final block it would not decrypted because
1418 EVP_CipherUpdate() would correctly report zero bytes had been decrypted.
1419 A misplaced 'break' also meant the decrypted final block might not be
1420 copied until the next read.
1423 *) Initial support for DH_METHOD. Again based on RSA_METHOD. Also added
1424 a few extra parameters to the DH structure: these will be useful if
1425 for example we want the value of 'q' or implement X9.42 DH.
1428 *) Initial support for DSA_METHOD. This is based on the RSA_METHOD and
1429 provides hooks that allow the default DSA functions or functions on a
1430 "per key" basis to be replaced. This allows hardware acceleration and
1431 hardware key storage to be handled without major modification to the
1432 library. Also added low level modexp hooks and CRYPTO_EX structure and
1433 associated functions.
1436 *) Add a new flag to memory BIOs, BIO_FLAG_MEM_RDONLY. This marks the BIO
1437 as "read only": it can't be written to and the buffer it points to will
1438 not be freed. Reading from a read only BIO is much more efficient than
1439 a normal memory BIO. This was added because there are several times when
1440 an area of memory needs to be read from a BIO. The previous method was
1441 to create a memory BIO and write the data to it, this results in two
1442 copies of the data and an O(n^2) reading algorithm. There is a new
1443 function BIO_new_mem_buf() which creates a read only memory BIO from
1444 an area of memory. Also modified the PKCS#7 routines to use read only
1448 *) Bugfix: ssl23_get_client_hello did not work properly when called in
1449 state SSL23_ST_SR_CLNT_HELLO_B, i.e. when the first 7 bytes of
1450 a SSLv2-compatible client hello for SSLv3 or TLSv1 could be read,
1451 but a retry condition occured while trying to read the rest.
1454 *) The PKCS7_ENC_CONTENT_new() function was setting the content type as
1455 NID_pkcs7_encrypted by default: this was wrong since this should almost
1456 always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle
1457 the encrypted data type: this is a more sensible place to put it and it
1458 allows the PKCS#12 code to be tidied up that duplicated this
1462 *) Changed obj_dat.pl script so it takes its input and output files on
1463 the command line. This should avoid shell escape redirection problems
1467 *) Initial support for certificate extension requests, these are included
1468 in things like Xenroll certificate requests. Included functions to allow
1469 extensions to be obtained and added.
1472 *) -crlf option to s_client and s_server for sending newlines as
1473 CRLF (as required by many protocols).
1476 Changes between 0.9.3a and 0.9.4 [09 Aug 1999]
1478 *) Install libRSAglue.a when OpenSSL is built with RSAref.
1479 [Ralf S. Engelschall]
1481 *) A few more ``#ifndef NO_FP_API / #endif'' pairs for consistency.
1482 [Andrija Antonijevic <TheAntony2@bigfoot.com>]
1484 *) Fix -startdate and -enddate (which was missing) arguments to 'ca'
1488 *) New function DSA_dup_DH, which duplicates DSA parameters/keys as
1489 DH parameters/keys (q is lost during that conversion, but the resulting
1490 DH parameters contain its length).
1492 For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is
1493 much faster than DH_generate_parameters (which creates parameters
1494 where p = 2*q + 1), and also the smaller q makes DH computations
1495 much more efficient (160-bit exponentiation instead of 1024-bit
1496 exponentiation); so this provides a convenient way to support DHE
1497 ciphersuites in SSL/TLS servers (see ssl/ssltest.c). It is of
1498 utter importance to use
1499 SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
1501 SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
1502 when such DH parameters are used, because otherwise small subgroup
1503 attacks may become possible!
1506 *) Avoid memory leak in i2d_DHparams.
1509 *) Allow the -k option to be used more than once in the enc program:
1510 this allows the same encrypted message to be read by multiple recipients.
1513 *) New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts
1514 an ASN1_OBJECT to a text string. If the "no_name" parameter is set then
1515 it will always use the numerical form of the OID, even if it has a short
1519 *) Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp
1520 method only got called if p,q,dmp1,dmq1,iqmp components were present,
1521 otherwise bn_mod_exp was called. In the case of hardware keys for example
1522 no private key components need be present and it might store extra data
1523 in the RSA structure, which cannot be accessed from bn_mod_exp.
1524 By setting RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for
1525 private key operations.
1528 *) Added support for SPARC Linux.
1531 *) pem_password_cb function type incompatibly changed from
1532 typedef int pem_password_cb(char *buf, int size, int rwflag);
1534 ....(char *buf, int size, int rwflag, void *userdata);
1535 so that applications can pass data to their callbacks:
1536 The PEM[_ASN1]_{read,write}... functions and macros now take an
1537 additional void * argument, which is just handed through whenever
1538 the password callback is called.
1539 [Damien Miller <dmiller@ilogic.com.au>; tiny changes by Bodo Moeller]
1541 New function SSL_CTX_set_default_passwd_cb_userdata.
1543 Compatibility note: As many C implementations push function arguments
1544 onto the stack in reverse order, the new library version is likely to
1545 interoperate with programs that have been compiled with the old
1546 pem_password_cb definition (PEM_whatever takes some data that
1547 happens to be on the stack as its last argument, and the callback
1548 just ignores this garbage); but there is no guarantee whatsoever that
1551 *) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=...
1552 (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused
1553 problems not only on Windows, but also on some Unix platforms.
1554 To avoid problematic command lines, these definitions are now in an
1555 auto-generated file crypto/buildinf.h (created by crypto/Makefile.ssl
1556 for standard "make" builds, by util/mk1mf.pl for "mk1mf" builds).
1559 *) MIPS III/IV assembler module is reimplemented.
1562 *) More DES library cleanups: remove references to srand/rand and
1563 delete an unused file.
1566 *) Add support for the the free Netwide assembler (NASM) under Win32,
1567 since not many people have MASM (ml) and it can be hard to obtain.
1568 This is currently experimental but it seems to work OK and pass all
1569 the tests. Check out INSTALL.W32 for info.
1572 *) Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections
1573 without temporary keys kept an extra copy of the server key,
1574 and connections with temporary keys did not free everything in case
1578 *) New function RSA_check_key and new openssl rsa option -check
1579 for verifying the consistency of RSA keys.
1580 [Ulf Moeller, Bodo Moeller]
1582 *) Various changes to make Win32 compile work:
1583 1. Casts to avoid "loss of data" warnings in p5_crpt2.c
1584 2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned
1585 comparison" warnings.
1586 3. Add sk_<TYPE>_sort to DEF file generator and do make update.
1589 *) Add a debugging option to PKCS#5 v2 key generation function: when
1590 you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and
1591 derived keys are printed to stderr.
1594 *) Copy the flags in ASN1_STRING_dup().
1595 [Roman E. Pavlov <pre@mo.msk.ru>]
1597 *) The x509 application mishandled signing requests containing DSA
1598 keys when the signing key was also DSA and the parameters didn't match.
1600 It was supposed to omit the parameters when they matched the signing key:
1601 the verifying software was then supposed to automatically use the CA's
1602 parameters if they were absent from the end user certificate.
1604 Omitting parameters is no longer recommended. The test was also
1605 the wrong way round! This was probably due to unusual behaviour in
1606 EVP_cmp_parameters() which returns 1 if the parameters match.
1607 This meant that parameters were omitted when they *didn't* match and
1608 the certificate was useless. Certificates signed with 'ca' didn't have
1610 [Steve Henson, reported by Doug Erickson <Doug.Erickson@Part.NET>]
1612 *) Memory leak checking (-DCRYPTO_MDEBUG) had some problems.
1613 The interface is as follows:
1614 Applications can use
1615 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(),
1616 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop();
1617 "off" is now the default.
1618 The library internally uses
1619 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(),
1620 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on()
1621 to disable memory-checking temporarily.
1623 Some inconsistent states that previously were possible (and were
1624 even the default) are now avoided.
1626 -DCRYPTO_MDEBUG_TIME is new and additionally stores the current time
1627 with each memory chunk allocated; this is occasionally more helpful
1628 than just having a counter.
1630 -DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID.
1632 -DCRYPTO_MDEBUG_ALL enables all of the above, plus any future
1636 *) Introduce "mode" for SSL structures (with defaults in SSL_CTX),
1637 which largely parallels "options", but is for changing API behaviour,
1638 whereas "options" are about protocol behaviour.
1639 Initial "mode" flags are:
1641 SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when
1642 a single record has been written.
1643 SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write
1644 retries use the same buffer location.
1645 (But all of the contents must be
1649 *) Bugfix: SSL_set_mode ignored its parameter, only SSL_CTX_set_mode
1652 *) Fix problems with no-hmac etc.
1653 [Ulf Möller, pointed out by Brian Wellington <bwelling@tislabs.com>]
1655 *) New functions RSA_get_default_method(), RSA_set_method() and
1656 RSA_get_method(). These allows replacement of RSA_METHODs without having
1657 to mess around with the internals of an RSA structure.
1660 *) Fix memory leaks in DSA_do_sign and DSA_is_prime.
1661 Also really enable memory leak checks in openssl.c and in some
1663 [Chad C. Mulligan, Bodo Moeller]
1665 *) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess
1666 up the length of negative integers. This has now been simplified to just
1667 store the length when it is first determined and use it later, rather
1668 than trying to keep track of where data is copied and updating it to
1670 [Steve Henson, reported by Brien Wheeler
1671 <bwheeler@authentica-security.com>]
1673 *) Add a new function PKCS7_signatureVerify. This allows the verification
1674 of a PKCS#7 signature but with the signing certificate passed to the
1675 function itself. This contrasts with PKCS7_dataVerify which assumes the
1676 certificate is present in the PKCS#7 structure. This isn't always the
1677 case: certificates can be omitted from a PKCS#7 structure and be
1678 distributed by "out of band" means (such as a certificate database).
1681 *) Complete the PEM_* macros with DECLARE_PEM versions to replace the
1682 function prototypes in pem.h, also change util/mkdef.pl to add the
1683 necessary function names.
1686 *) mk1mf.pl (used by Windows builds) did not properly read the
1687 options set by Configure in the top level Makefile, and Configure
1688 was not even able to write more than one option correctly.
1689 Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended.
1692 *) New functions CONF_load_bio() and CONF_load_fp() to allow a config
1693 file to be loaded from a BIO or FILE pointer. The BIO version will
1694 for example allow memory BIOs to contain config info.
1697 *) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS.
1698 Whoever hopes to achieve shared-library compatibility across versions
1699 must use this, not the compile-time macro.
1700 (Exercise 0.9.4: Which is the minimum library version required by
1702 Note: All this applies only to multi-threaded programs, others don't
1706 *) Add missing case to s3_clnt.c state machine -- one of the new SSL tests
1707 through a BIO pair triggered the default case, i.e.
1708 SSLerr(...,SSL_R_UNKNOWN_STATE).
1711 *) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications
1712 can use the SSL library even if none of the specific BIOs is
1716 *) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value
1717 for the encoded length.
1718 [Jeon KyoungHo <khjeon@sds.samsung.co.kr>]
1720 *) Add initial documentation of the X509V3 functions.
1723 *) Add a new pair of functions PEM_write_PKCS8PrivateKey() and
1724 PEM_write_bio_PKCS8PrivateKey() that are equivalent to
1725 PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more
1726 secure PKCS#8 private key format with a high iteration count.
1729 *) Fix determination of Perl interpreter: A perl or perl5
1730 _directory_ in $PATH was also accepted as the interpreter.
1731 [Ralf S. Engelschall]
1733 *) Fix demos/sign/sign.c: well there wasn't anything strictly speaking
1734 wrong with it but it was very old and did things like calling
1735 PEM_ASN1_read() directly and used MD5 for the hash not to mention some
1739 *) Fix demos/selfsign.c: it used obsolete and deleted functions, changed
1740 to use the new extension code.
1743 *) Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c
1744 with macros. This should make it easier to change their form, add extra
1745 arguments etc. Fix a few PEM prototypes which didn't have cipher as a
1749 *) Add to configuration table a new entry that can specify an alternative
1750 name for unistd.h (for pre-POSIX systems); we need this for NeXTstep,
1751 according to Mark Crispin <MRC@Panda.COM>.
1755 *) DES CBC did not update the IV. Weird.
1758 des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does.
1759 Changing the behaviour of the former might break existing programs --
1760 where IV updating is needed, des_ncbc_encrypt can be used.
1763 *) When bntest is run from "make test" it drives bc to check its
1764 calculations, as well as internally checking them. If an internal check
1765 fails, it needs to cause bc to give a non-zero result or make test carries
1766 on without noticing the failure. Fixed.
1769 *) DES library cleanups.
1772 *) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be
1773 used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit
1774 ciphers. NOTE: although the key derivation function has been verified
1775 against some published test vectors it has not been extensively tested
1776 yet. Added a -v2 "cipher" option to pkcs8 application to allow the use
1780 *) Instead of "mkdir -p", which is not fully portable, use new
1781 Perl script "util/mkdir-p.pl".
1784 *) Rewrite the way password based encryption (PBE) is handled. It used to
1785 assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter
1786 structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms
1787 but doesn't apply to PKCS#5 v2.0 where it can be something else. Now
1788 the 'parameter' field of the AlgorithmIdentifier is passed to the
1789 underlying key generation function so it must do its own ASN1 parsing.
1790 This has also changed the EVP_PBE_CipherInit() function which now has a
1791 'parameter' argument instead of literal salt and iteration count values
1792 and the function EVP_PBE_ALGOR_CipherInit() has been deleted.
1795 *) Support for PKCS#5 v1.5 compatible password based encryption algorithms
1796 and PKCS#8 functionality. New 'pkcs8' application linked to openssl.
1797 Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE
1798 KEY" because this clashed with PKCS#8 unencrypted string. Since this
1799 value was just used as a "magic string" and not used directly its
1800 value doesn't matter.
1803 *) Introduce some semblance of const correctness to BN. Shame C doesn't
1807 *) "linux-sparc64" configuration (ultrapenguin).
1808 [Ray Miller <ray.miller@oucs.ox.ac.uk>]
1809 "linux-sparc" configuration.
1810 [Christian Forster <fo@hawo.stw.uni-erlangen.de>]
1812 *) config now generates no-xxx options for missing ciphers.
1815 *) Support the EBCDIC character set (work in progress).
1816 File ebcdic.c not yet included because it has a different license.
1817 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
1819 *) Support BS2000/OSD-POSIX.
1820 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
1822 *) Make callbacks for key generation use void * instead of char *.
1825 *) Make S/MIME samples compile (not yet tested).
1828 *) Additional typesafe stacks.
1831 *) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x).
1835 Changes between 0.9.3 and 0.9.3a [29 May 1999]
1837 *) New configuration variant "sco5-gcc".
1839 *) Updated some demos.
1840 [Sean O Riordain, Wade Scholine]
1842 *) Add missing BIO_free at exit of pkcs12 application.
1845 *) Fix memory leak in conf.c.
1848 *) Updates for Win32 to assembler version of MD5.
1851 *) Set #! path to perl in apps/der_chop to where we found it
1852 instead of using a fixed path.
1855 *) SHA library changes for irix64-mips4-cc.
1858 *) Improvements for VMS support.
1862 Changes between 0.9.2b and 0.9.3 [24 May 1999]
1864 *) Bignum library bug fix. IRIX 6 passes "make test" now!
1865 This also avoids the problems with SC4.2 and unpatched SC5.
1866 [Andy Polyakov <appro@fy.chalmers.se>]
1868 *) New functions sk_num, sk_value and sk_set to replace the previous macros.
1869 These are required because of the typesafe stack would otherwise break
1870 existing code. If old code used a structure member which used to be STACK
1871 and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with
1872 sk_num or sk_value it would produce an error because the num, data members
1873 are not present in STACK_OF. Now it just produces a warning. sk_set
1874 replaces the old method of assigning a value to sk_value
1875 (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code
1876 that does this will no longer work (and should use sk_set instead) but
1877 this could be regarded as a "questionable" behaviour anyway.
1880 *) Fix most of the other PKCS#7 bugs. The "experimental" code can now
1881 correctly handle encrypted S/MIME data.
1884 *) Change type of various DES function arguments from des_cblock
1885 (which means, in function argument declarations, pointer to char)
1886 to des_cblock * (meaning pointer to array with 8 char elements),
1887 which allows the compiler to do more typechecking; it was like
1888 that back in SSLeay, but with lots of ugly casts.
1890 Introduce new type const_des_cblock.
1893 *) Reorganise the PKCS#7 library and get rid of some of the more obvious
1894 problems: find RecipientInfo structure that matches recipient certificate
1895 and initialise the ASN1 structures properly based on passed cipher.
1898 *) Belatedly make the BN tests actually check the results.
1901 *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion
1902 to and from BNs: it was completely broken. New compilation option
1903 NEG_PUBKEY_BUG to allow for some broken certificates that encode public
1904 key elements as negative integers.
1907 *) Reorganize and speed up MD5.
1908 [Andy Polyakov <appro@fy.chalmers.se>]
1911 [Richard Levitte <richard@levitte.org>]
1913 *) New option -out to asn1parse to allow the parsed structure to be
1914 output to a file. This is most useful when combined with the -strparse
1915 option to examine the output of things like OCTET STRINGS.
1918 *) Make SSL library a little more fool-proof by not requiring any longer
1919 that SSL_set_{accept,connect}_state be called before
1920 SSL_{accept,connect} may be used (SSL_set_..._state is omitted
1921 in many applications because usually everything *appeared* to work as
1922 intended anyway -- now it really works as intended).
1925 *) Move openssl.cnf out of lib/.
1928 *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall
1929 -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
1930 -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+
1931 [Ralf S. Engelschall]
1933 *) Various fixes to the EVP and PKCS#7 code. It may now be able to
1934 handle PKCS#7 enveloped data properly.
1935 [Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve]
1937 *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
1938 copying pointers. The cert_st handling is changed by this in
1939 various ways (and thus what used to be known as ctx->default_cert
1940 is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
1941 any longer when s->cert does not give us what we need).
1942 ssl_cert_instantiate becomes obsolete by this change.
1943 As soon as we've got the new code right (possibly it already is?),
1944 we have solved a couple of bugs of the earlier code where s->cert
1945 was used as if it could not have been shared with other SSL structures.
1947 Note that using the SSL API in certain dirty ways now will result
1948 in different behaviour than observed with earlier library versions:
1949 Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
1950 does not influence s as it used to.
1952 In order to clean up things more thoroughly, inside SSL_SESSION
1953 we don't use CERT any longer, but a new structure SESS_CERT
1954 that holds per-session data (if available); currently, this is
1955 the peer's certificate chain and, for clients, the server's certificate
1956 and temporary key. CERT holds only those values that can have
1957 meaningful defaults in an SSL_CTX.
1960 *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure
1961 from the internal representation. Various PKCS#7 fixes: remove some
1962 evil casts and set the enc_dig_alg field properly based on the signing
1966 *) Allow PKCS#12 password to be set from the command line or the
1967 environment. Let 'ca' get its config file name from the environment
1968 variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req'
1972 *) Allow certificate policies extension to use an IA5STRING for the
1973 organization field. This is contrary to the PKIX definition but
1974 VeriSign uses it and IE5 only recognises this form. Document 'x509'
1978 *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic,
1979 without disallowing inline assembler and the like for non-pedantic builds.
1982 *) Support Borland C++ builder.
1983 [Janez Jere <jj@void.si>, modified by Ulf Möller]
1988 *) SHA-1 cleanups and performance enhancements.
1989 [Andy Polyakov <appro@fy.chalmers.se>]
1991 *) Sparc v8plus assembler for the bignum library.
1992 [Andy Polyakov <appro@fy.chalmers.se>]
1994 *) Accept any -xxx and +xxx compiler options in Configure.
1997 *) Update HPUX configuration.
2000 *) Add missing sk_<type>_unshift() function to safestack.h
2001 [Ralf S. Engelschall]
2003 *) New function SSL_CTX_use_certificate_chain_file that sets the
2004 "extra_cert"s in addition to the certificate. (This makes sense
2005 only for "PEM" format files, as chains as a whole are not
2009 *) Support verify_depth from the SSL API.
2010 x509_vfy.c had what can be considered an off-by-one-error:
2011 Its depth (which was not part of the external interface)
2012 was actually counting the number of certificates in a chain;
2013 now it really counts the depth.
2016 *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used
2017 instead of X509err, which often resulted in confusing error
2018 messages since the error codes are not globally unique
2019 (e.g. an alleged error in ssl3_accept when a certificate
2020 didn't match the private key).
2022 *) New function SSL_CTX_set_session_id_context that allows to set a default
2023 value (so that you don't need SSL_set_session_id_context for each
2024 connection using the SSL_CTX).
2027 *) OAEP decoding bug fix.
2030 *) Support INSTALL_PREFIX for package builders, as proposed by
2034 *) New Configure options "threads" and "no-threads". For systems
2035 where the proper compiler options are known (currently Solaris
2036 and Linux), "threads" is the default.
2039 *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
2042 *) Install various scripts to $(OPENSSLDIR)/misc, not to
2043 $(INSTALLTOP)/bin -- they shouldn't clutter directories
2044 such as /usr/local/bin.
2047 *) "make linux-shared" to build shared libraries.
2048 [Niels Poppe <niels@netbox.org>]
2050 *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
2053 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
2054 extension adding in x509 utility.
2057 *) Remove NOPROTO sections and error code comments.
2060 *) Partial rewrite of the DEF file generator to now parse the ANSI
2064 *) New Configure options --prefix=DIR and --openssldir=DIR.
2067 *) Complete rewrite of the error code script(s). It is all now handled
2068 by one script at the top level which handles error code gathering,
2069 header rewriting and C source file generation. It should be much better
2070 than the old method: it now uses a modified version of Ulf's parser to
2071 read the ANSI prototypes in all header files (thus the old K&R definitions
2072 aren't needed for error creation any more) and do a better job of
2073 translating function codes into names. The old 'ASN1 error code imbedded
2074 in a comment' is no longer necessary and it doesn't use .err files which
2075 have now been deleted. Also the error code call doesn't have to appear all
2076 on one line (which resulted in some large lines...).
2079 *) Change #include filenames from <foo.h> to <openssl/foo.h>.
2082 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
2083 0 (which usually indicates a closed connection), but continue reading.
2086 *) Fix some race conditions.
2089 *) Add support for CRL distribution points extension. Add Certificate
2090 Policies and CRL distribution points documentation.
2093 *) Move the autogenerated header file parts to crypto/opensslconf.h.
2096 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
2097 8 of keying material. Merlin has also confirmed interop with this fix
2098 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
2099 [Merlin Hughes <merlin@baltimore.ie>]
2101 *) Fix lots of warnings.
2102 [Richard Levitte <levitte@stacken.kth.se>]
2104 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
2105 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
2106 [Richard Levitte <levitte@stacken.kth.se>]
2108 *) Fix problems with sizeof(long) == 8.
2109 [Andy Polyakov <appro@fy.chalmers.se>]
2111 *) Change functions to ANSI C.
2114 *) Fix typos in error codes.
2115 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
2117 *) Remove defunct assembler files from Configure.
2120 *) SPARC v8 assembler BIGNUM implementation.
2121 [Andy Polyakov <appro@fy.chalmers.se>]
2123 *) Support for Certificate Policies extension: both print and set.
2124 Various additions to support the r2i method this uses.
2127 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
2128 return a const string when you are expecting an allocated buffer.
2131 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
2132 types DirectoryString and DisplayText.
2135 *) Add code to allow r2i extensions to access the configuration database,
2136 add an LHASH database driver and add several ctx helper functions.
2139 *) Fix an evil bug in bn_expand2() which caused various BN functions to
2140 fail when they extended the size of a BIGNUM.
2143 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
2144 support typesafe stack.
2147 *) Fix typo in SSL_[gs]et_options().
2148 [Nils Frostberg <nils@medcom.se>]
2150 *) Delete various functions and files that belonged to the (now obsolete)
2151 old X509V3 handling code.
2154 *) New Configure option "rsaref".
2157 *) Don't auto-generate pem.h.
2160 *) Introduce type-safe ASN.1 SETs.
2163 *) Convert various additional casted stacks to type-safe STACK_OF() variants.
2164 [Ben Laurie, Ralf S. Engelschall, Steve Henson]
2166 *) Introduce type-safe STACKs. This will almost certainly break lots of code
2167 that links with OpenSSL (well at least cause lots of warnings), but fear
2168 not: the conversion is trivial, and it eliminates loads of evil casts. A
2169 few STACKed things have been converted already. Feel free to convert more.
2170 In the fullness of time, I'll do away with the STACK type altogether.
2173 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
2174 specified in <certfile> by updating the entry in the index.txt file.
2175 This way one no longer has to edit the index.txt file manually for
2176 revoking a certificate. The -revoke option does the gory details now.
2177 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
2179 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
2180 `-text' option at all and this way the `-noout -text' combination was
2181 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
2182 [Ralf S. Engelschall]
2184 *) Make sure a corresponding plain text error message exists for the
2185 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
2186 verify callback function determined that a certificate was revoked.
2187 [Ralf S. Engelschall]
2189 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
2190 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
2191 all available cipers including rc5, which was forgotten until now.
2192 In order to let the testing shell script know which algorithms
2193 are available, a new (up to now undocumented) command
2194 "openssl list-cipher-commands" is used.
2197 *) Bugfix: s_client occasionally would sleep in select() when
2198 it should have checked SSL_pending() first.
2201 *) New functions DSA_do_sign and DSA_do_verify to provide access to
2202 the raw DSA values prior to ASN.1 encoding.
2205 *) Tweaks to Configure
2206 [Niels Poppe <niels@netbox.org>]
2208 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
2212 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
2215 *) New config option to avoid instructions that are illegal on the 80386.
2216 The default code is faster, but requires at least a 486.
2219 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
2220 SSL2_SERVER_VERSION (not used at all) macros, which are now the
2221 same as SSL2_VERSION anyway.
2224 *) New "-showcerts" option for s_client.
2227 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
2228 application. Various cleanups and fixes.
2231 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
2232 modify error routines to work internally. Add error codes and PBE init
2233 to library startup routines.
2236 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
2237 packing functions to asn1 and evp. Changed function names and error
2238 codes along the way.
2241 *) PKCS12 integration: and so it begins... First of several patches to
2242 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
2243 objects to objects.h
2246 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
2247 and display support for Thawte strong extranet extension.
2250 *) Add LinuxPPC support.
2251 [Jeff Dubrule <igor@pobox.org>]
2253 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
2254 bn_div_words in alpha.s.
2255 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
2257 *) Make sure the RSA OAEP test is skipped under -DRSAref because
2258 OAEP isn't supported when OpenSSL is built with RSAref.
2259 [Ulf Moeller <ulf@fitug.de>]
2261 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
2262 so they no longer are missing under -DNOPROTO.
2263 [Soren S. Jorvang <soren@t.dk>]
2266 Changes between 0.9.1c and 0.9.2b [22 Mar 1999]
2268 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
2269 doesn't work when the session is reused. Coming soon!
2272 *) Fix a security hole, that allows sessions to be reused in the wrong
2273 context thus bypassing client cert protection! All software that uses
2274 client certs and session caches in multiple contexts NEEDS PATCHING to
2275 allow session reuse! A fuller solution is in the works.
2276 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
2278 *) Some more source tree cleanups (removed obsolete files
2279 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
2280 permission on "config" script to be executable) and a fix for the INSTALL
2282 [Ulf Moeller <ulf@fitug.de>]
2284 *) Remove some legacy and erroneous uses of malloc, free instead of
2286 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
2288 *) Make rsa_oaep_test return non-zero on error.
2289 [Ulf Moeller <ulf@fitug.de>]
2291 *) Add support for native Solaris shared libraries. Configure
2292 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
2293 if someone would make that last step automatic.
2294 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
2296 *) ctx_size was not built with the right compiler during "make links". Fixed.
2299 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
2300 except NULL ciphers". This means the default cipher list will no longer
2301 enable NULL ciphers. They need to be specifically enabled e.g. with
2302 the string "DEFAULT:eNULL".
2305 *) Fix to RSA private encryption routines: if p < q then it would
2306 occasionally produce an invalid result. This will only happen with
2307 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
2310 *) Be less restrictive and allow also `perl util/perlpath.pl
2311 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
2312 because this way one can also use an interpreter named `perl5' (which is
2313 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
2314 installed as `perl').
2315 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
2317 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
2318 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
2320 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
2321 advapi32.lib to Win32 build and change the pem test comparision
2322 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
2323 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
2324 and crypto/des/ede_cbcm_enc.c.
2327 *) DES quad checksum was broken on big-endian architectures. Fixed.
2330 *) Comment out two functions in bio.h that aren't implemented. Fix up the
2331 Win32 test batch file so it (might) work again. The Win32 test batch file
2332 is horrible: I feel ill....
2335 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
2336 in e_os.h. Audit of header files to check ANSI and non ANSI
2337 sections: 10 functions were absent from non ANSI section and not exported
2338 from Windows DLLs. Fixed up libeay.num for new functions.
2341 *) Make `openssl version' output lines consistent.
2342 [Ralf S. Engelschall]
2344 *) Fix Win32 symbol export lists for BIO functions: Added
2345 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
2346 to ms/libeay{16,32}.def.
2347 [Ralf S. Engelschall]
2349 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
2350 fine under Unix and passes some trivial tests I've now added. But the
2351 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
2352 added to make sure no one expects that this stuff really works in the
2353 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
2354 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
2356 [Ralf S. Engelschall]
2358 *) Fix the generation of two part addresses in perl.
2359 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
2361 *) Add config entry for Linux on MIPS.
2362 [John Tobey <jtobey@channel1.com>]
2364 *) Make links whenever Configure is run, unless we are on Windoze.
2367 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
2368 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
2372 *) Add a useful kludge to allow package maintainers to specify compiler and
2373 other platforms details on the command line without having to patch the
2374 Configure script everytime: One now can use ``perl Configure
2375 <id>:<details>'', i.e. platform ids are allowed to have details appended
2376 to them (seperated by colons). This is treated as there would be a static
2377 pre-configured entry in Configure's %table under key <id> with value
2378 <details> and ``perl Configure <id>'' is called. So, when you want to
2379 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
2380 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
2381 now, which overrides the FreeBSD-elf entry on-the-fly.
2382 [Ralf S. Engelschall]
2384 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
2387 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
2388 on the `perl Configure ...' command line. This way one can compile
2389 OpenSSL libraries with Position Independent Code (PIC) which is needed
2390 for linking it into DSOs.
2391 [Ralf S. Engelschall]
2393 *) Remarkably, export ciphers were totally broken and no-one had noticed!
2397 *) Cleaned up the LICENSE document: The official contact for any license
2398 questions now is the OpenSSL core team under openssl-core@openssl.org.
2399 And add a paragraph about the dual-license situation to make sure people
2400 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
2401 to the OpenSSL toolkit.
2402 [Ralf S. Engelschall]
2404 *) General source tree makefile cleanups: Made `making xxx in yyy...'
2405 display consistent in the source tree and replaced `/bin/rm' by `rm'.
2406 Additonally cleaned up the `make links' target: Remove unnecessary
2407 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
2408 to speed processing and no longer clutter the display with confusing
2409 stuff. Instead only the actually done links are displayed.
2410 [Ralf S. Engelschall]
2412 *) Permit null encryption ciphersuites, used for authentication only. It used
2413 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
2414 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
2418 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
2419 signed attributes when verifying signatures (this would break them),
2420 the detached data encoding was wrong and public keys obtained using
2421 X509_get_pubkey() weren't freed.
2424 *) Add text documentation for the BUFFER functions. Also added a work around
2425 to a Win95 console bug. This was triggered by the password read stuff: the
2426 last character typed gets carried over to the next fread(). If you were
2427 generating a new cert request using 'req' for example then the last
2428 character of the passphrase would be CR which would then enter the first
2432 *) Added the new `Includes OpenSSL Cryptography Software' button as
2433 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
2434 button and can be used by applications based on OpenSSL to show the
2435 relationship to the OpenSSL project.
2436 [Ralf S. Engelschall]
2438 *) Remove confusing variables in function signatures in files
2439 ssl/ssl_lib.c and ssl/ssl.h.
2440 [Lennart Bong <lob@kulthea.stacken.kth.se>]
2442 *) Don't install bss_file.c under PREFIX/include/
2443 [Lennart Bong <lob@kulthea.stacken.kth.se>]
2445 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
2446 functions that return function pointers and has support for NT specific
2447 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
2448 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
2449 unsigned to signed types: this was killing the Win32 compile.
2452 *) Add new certificate file to stack functions,
2453 SSL_add_dir_cert_subjects_to_stack() and
2454 SSL_add_file_cert_subjects_to_stack(). These largely supplant
2455 SSL_load_client_CA_file(), and can be used to add multiple certs easily
2456 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
2457 This means that Apache-SSL and similar packages don't have to mess around
2458 to add as many CAs as they want to the preferred list.
2461 *) Experiment with doxygen documentation. Currently only partially applied to
2463 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
2464 openssl.doxy as the configuration file.
2467 *) Get rid of remaining C++-style comments which strict C compilers hate.
2468 [Ralf S. Engelschall, pointed out by Carlos Amengual]
2470 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
2471 compiled in by default: it has problems with large keys.
2474 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
2475 DH private keys and/or callback functions which directly correspond to
2476 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
2477 is needed for applications which have to configure certificates on a
2478 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
2480 For the RSA certificate situation is makes no difference, but
2481 for the DSA certificate situation this fixes the "no shared cipher"
2482 problem where the OpenSSL cipher selection procedure failed because the
2483 temporary keys were not overtaken from the context and the API provided
2484 no way to reconfigure them.
2485 The new functions now let applications reconfigure the stuff and they
2486 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
2487 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
2488 non-public-API function ssl_cert_instantiate() is used as a helper
2489 function and also to reduce code redundancy inside ssl_rsa.c.
2490 [Ralf S. Engelschall]
2492 *) Move s_server -dcert and -dkey options out of the undocumented feature
2493 area because they are useful for the DSA situation and should be
2494 recognized by the users.
2495 [Ralf S. Engelschall]
2497 *) Fix the cipher decision scheme for export ciphers: the export bits are
2498 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
2499 SSL_EXP_MASK. So, the original variable has to be used instead of the
2500 already masked variable.
2501 [Richard Levitte <levitte@stacken.kth.se>]
2503 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
2504 [Richard Levitte <levitte@stacken.kth.se>]
2506 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
2507 from `int' to `unsigned int' because it's a length and initialized by
2508 EVP_DigestFinal() which expects an `unsigned int *'.
2509 [Richard Levitte <levitte@stacken.kth.se>]
2511 *) Don't hard-code path to Perl interpreter on shebang line of Configure
2512 script. Instead use the usual Shell->Perl transition trick.
2513 [Ralf S. Engelschall]
2515 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
2516 (in addition to RSA certificates) to match the behaviour of `openssl dsa
2517 -noout -modulus' as it's already the case for `openssl rsa -noout
2518 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
2519 currently the public key is printed (a decision which was already done by
2520 `openssl dsa -modulus' in the past) which serves a similar purpose.
2521 Additionally the NO_RSA no longer completely removes the whole -modulus
2522 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
2524 [Ralf S. Engelschall]
2526 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
2527 BIO. See the source (crypto/evp/bio_ok.c) for more info.
2528 [Arne Ansper <arne@ats.cyber.ee>]
2530 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
2531 to be added. Now both 'req' and 'ca' can use new objects defined in the
2535 *) Add cool BIO that does syslog (or event log on NT).
2536 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
2538 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
2539 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
2540 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
2541 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
2544 *) Add preliminary config info for new extension code.
2547 *) Make RSA_NO_PADDING really use no padding.
2548 [Ulf Moeller <ulf@fitug.de>]
2550 *) Generate errors when private/public key check is done.
2553 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
2554 for some CRL extensions and new objects added.
2557 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
2558 key usage extension and fuller support for authority key id.
2561 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
2562 padding method for RSA, which is recommended for new applications in PKCS
2563 #1 v2.0 (RFC 2437, October 1998).
2564 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
2565 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
2566 against Bleichbacher's attack on RSA.
2567 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
2570 *) Updates to the new SSL compression code
2571 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
2573 *) Fix so that the version number in the master secret, when passed
2574 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
2575 (because the server will not accept higher), that the version number
2576 is 0x03,0x01, not 0x03,0x00
2577 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
2579 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
2580 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
2581 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
2584 *) Support for RAW extensions where an arbitrary extension can be
2585 created by including its DER encoding. See apps/openssl.cnf for
2589 *) Make sure latest Perl versions don't interpret some generated C array
2590 code as Perl array code in the crypto/err/err_genc.pl script.
2591 [Lars Weber <3weber@informatik.uni-hamburg.de>]
2593 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
2594 not many people have the assembler. Various Win32 compilation fixes and
2595 update to the INSTALL.W32 file with (hopefully) more accurate Win32
2599 *) Modify configure script 'Configure' to automatically create crypto/date.h
2600 file under Win32 and also build pem.h from pem.org. New script
2601 util/mkfiles.pl to create the MINFO file on environments that can't do a
2602 'make files': perl util/mkfiles.pl >MINFO should work.
2605 *) Major rework of DES function declarations, in the pursuit of correctness
2606 and purity. As a result, many evil casts evaporated, and some weirdness,
2607 too. You may find this causes warnings in your code. Zapping your evil
2608 casts will probably fix them. Mostly.
2611 *) Fix for a typo in asn1.h. Bug fix to object creation script
2612 obj_dat.pl. It considered a zero in an object definition to mean
2613 "end of object": none of the objects in objects.h have any zeros
2614 so it wasn't spotted.
2615 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
2617 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
2618 Masking (CBCM). In the absence of test vectors, the best I have been able
2619 to do is check that the decrypt undoes the encrypt, so far. Send me test
2620 vectors if you have them.
2623 *) Correct calculation of key length for export ciphers (too much space was
2624 allocated for null ciphers). This has not been tested!
2627 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
2628 message is now correct (it understands "crypto" and "ssl" on its
2629 command line). There is also now an "update" option. This will update
2630 the util/ssleay.num and util/libeay.num files with any new functions.
2632 perl util/mkdef.pl crypto ssl update
2633 it will update them.
2636 *) Overhauled the Perl interface (perl/*):
2637 - ported BN stuff to OpenSSL's different BN library
2638 - made the perl/ source tree CVS-aware
2639 - renamed the package from SSLeay to OpenSSL (the files still contain
2640 their history because I've copied them in the repository)
2641 - removed obsolete files (the test scripts will be replaced
2642 by better Test::Harness variants in the future)
2643 [Ralf S. Engelschall]
2645 *) First cut for a very conservative source tree cleanup:
2646 1. merge various obsolete readme texts into doc/ssleay.txt
2647 where we collect the old documents and readme texts.
2648 2. remove the first part of files where I'm already sure that we no
2649 longer need them because of three reasons: either they are just temporary
2650 files which were left by Eric or they are preserved original files where
2651 I've verified that the diff is also available in the CVS via "cvs diff
2652 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
2653 the crypto/md/ stuff).
2654 [Ralf S. Engelschall]
2656 *) More extension code. Incomplete support for subject and issuer alt
2657 name, issuer and authority key id. Change the i2v function parameters
2658 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
2659 what that's for :-) Fix to ASN1 macro which messed up
2660 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
2663 *) Preliminary support for ENUMERATED type. This is largely copied from the
2667 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
2668 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
2670 *) Make sure `make rehash' target really finds the `openssl' program.
2671 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
2673 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
2674 like to hear about it if this slows down other processors.
2677 *) Add CygWin32 platform information to Configure script.
2678 [Alan Batie <batie@aahz.jf.intel.com>]
2680 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
2681 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
2683 *) New program nseq to manipulate netscape certificate sequences
2686 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
2690 *) Fixes to BN code. Previously the default was to define BN_RECURSION
2691 but the BN code had some problems that would cause failures when
2692 doing certificate verification and some other functions.
2693 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
2695 *) Add ASN1 and PEM code to support netscape certificate sequences.
2698 *) Add ASN1 and PEM code to support netscape certificate sequences.
2701 *) Add several PKIX and private extended key usage OIDs.
2704 *) Modify the 'ca' program to handle the new extension code. Modify
2705 openssl.cnf for new extension format, add comments.
2708 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
2709 and add a sample to openssl.cnf so req -x509 now adds appropriate
2713 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
2714 error code, add initial support to X509_print() and x509 application.
2717 *) Takes a deep breath and start addding X509 V3 extension support code. Add
2718 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
2719 stuff is currently isolated and isn't even compiled yet.
2722 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
2723 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
2724 Removed the versions check from X509 routines when loading extensions:
2725 this allows certain broken certificates that don't set the version
2726 properly to be processed.
2729 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
2730 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
2731 can still be regenerated with "make depend".
2734 *) Spelling mistake in C version of CAST-128.
2735 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
2737 *) Changes to the error generation code. The perl script err-code.pl
2738 now reads in the old error codes and retains the old numbers, only
2739 adding new ones if necessary. It also only changes the .err files if new
2740 codes are added. The makefiles have been modified to only insert errors
2741 when needed (to avoid needlessly modifying header files). This is done
2742 by only inserting errors if the .err file is newer than the auto generated
2743 C file. To rebuild all the error codes from scratch (the old behaviour)
2744 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
2745 or delete all the .err files.
2748 *) CAST-128 was incorrectly implemented for short keys. The C version has
2749 been fixed, but is untested. The assembler versions are also fixed, but
2750 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
2751 to regenerate it if needed.
2752 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
2753 Hagino <itojun@kame.net>]
2755 *) File was opened incorrectly in randfile.c.
2756 [Ulf Möller <ulf@fitug.de>]
2758 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
2759 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
2760 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
2761 al: it's just almost always a UTCTime. Note this patch adds new error
2762 codes so do a "make errors" if there are problems.
2765 *) Correct Linux 1 recognition in config.
2766 [Ulf Möller <ulf@fitug.de>]
2768 *) Remove pointless MD5 hash when using DSA keys in ca.
2769 [Anonymous <nobody@replay.com>]
2771 *) Generate an error if given an empty string as a cert directory. Also
2772 generate an error if handed NULL (previously returned 0 to indicate an
2773 error, but didn't set one).
2774 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
2776 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
2779 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
2780 parameters. This was causing a warning which killed off the Win32 compile.
2783 *) Remove C++ style comments from crypto/bn/bn_local.h.
2784 [Neil Costigan <neil.costigan@celocom.com>]
2786 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
2787 based on a text string, looking up short and long names and finally
2788 "dot" format. The "dot" format stuff didn't work. Added new function
2789 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
2790 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
2791 OID is not part of the table.
2794 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
2795 X509_LOOKUP_by_alias().
2798 *) Sort openssl functions by name.
2801 *) Get the gendsa program working (hopefully) and add it to app list. Remove
2802 encryption from sample DSA keys (in case anyone is interested the password
2806 *) Make _all_ *_free functions accept a NULL pointer.
2807 [Frans Heymans <fheymans@isaserver.be>]
2809 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
2811 [Anonymous <nobody@replay.com>]
2813 *) s_server should send the CAfile as acceptable CAs, not its own cert.
2814 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
2816 *) Don't blow it for numeric -newkey arguments to apps/req.
2817 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
2819 *) Temp key "for export" tests were wrong in s3_srvr.c.
2820 [Anonymous <nobody@replay.com>]
2822 *) Add prototype for temp key callback functions
2823 SSL_CTX_set_tmp_{rsa,dh}_callback().
2826 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
2827 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
2830 *) X509_name_add_entry() freed the wrong thing after an error.
2831 [Arne Ansper <arne@ats.cyber.ee>]
2833 *) rsa_eay.c would attempt to free a NULL context.
2834 [Arne Ansper <arne@ats.cyber.ee>]
2836 *) BIO_s_socket() had a broken should_retry() on Windoze.
2837 [Arne Ansper <arne@ats.cyber.ee>]
2839 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
2840 [Arne Ansper <arne@ats.cyber.ee>]
2842 *) Make sure the already existing X509_STORE->depth variable is initialized
2843 in X509_STORE_new(), but document the fact that this variable is still
2844 unused in the certificate verification process.
2845 [Ralf S. Engelschall]
2847 *) Fix the various library and apps files to free up pkeys obtained from
2848 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
2851 *) Fix reference counting in X509_PUBKEY_get(). This makes
2852 demos/maurice/example2.c work, amongst others, probably.
2853 [Steve Henson and Ben Laurie]
2855 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
2856 `openssl' and second, the shortcut symlinks for the `openssl <command>'
2857 are no longer created. This way we have a single and consistent command
2858 line interface `openssl <command>', similar to `cvs <command>'.
2859 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
2861 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
2862 BIT STRING wrapper always have zero unused bits.
2865 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
2868 *) Make the top-level INSTALL documentation easier to understand.
2871 *) Makefiles updated to exit if an error occurs in a sub-directory
2872 make (including if user presses ^C) [Paul Sutton]
2874 *) Make Montgomery context stuff explicit in RSA data structure.
2877 *) Fix build order of pem and err to allow for generated pem.h.
2880 *) Fix renumbering bug in X509_NAME_delete_entry().
2883 *) Enhanced the err-ins.pl script so it makes the error library number
2884 global and can add a library name. This is needed for external ASN1 and
2885 other error libraries.
2888 *) Fixed sk_insert which never worked properly.
2891 *) Fix ASN1 macros so they can handle indefinite length construted
2892 EXPLICIT tags. Some non standard certificates use these: they can now
2896 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
2897 into a single doc/ssleay.txt bundle. This way the information is still
2898 preserved but no longer messes up this directory. Now it's new room for
2899 the new set of documenation files.
2900 [Ralf S. Engelschall]
2902 *) SETs were incorrectly DER encoded. This was a major pain, because they
2903 shared code with SEQUENCEs, which aren't coded the same. This means that
2904 almost everything to do with SETs or SEQUENCEs has either changed name or
2905 number of arguments.
2906 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
2908 *) Fix test data to work with the above.
2911 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
2912 was already fixed by Eric for 0.9.1 it seems.
2913 [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
2915 *) Autodetect FreeBSD3.
2918 *) Fix various bugs in Configure. This affects the following platforms:
2922 unixware-2.0-pentium
2926 *) Eliminate generated files from CVS. Reorder tests to regenerate files
2927 before they are needed.
2930 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
2934 Changes between 0.9.1b and 0.9.1c [23-Dec-1998]
2936 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
2937 changed SSLeay to OpenSSL in version strings.
2938 [Ralf S. Engelschall]
2940 *) Some fixups to the top-level documents.
2943 *) Fixed the nasty bug where rsaref.h was not found under compile-time
2944 because the symlink to include/ was missing.
2945 [Ralf S. Engelschall]
2947 *) Incorporated the popular no-RSA/DSA-only patches
2948 which allow to compile a RSA-free SSLeay.
2949 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
2951 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
2952 when "ssleay" is still not found.
2953 [Ralf S. Engelschall]
2955 *) Added more platforms to Configure: Cray T3E, HPUX 11,
2956 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
2958 *) Updated the README file.
2959 [Ralf S. Engelschall]
2961 *) Added various .cvsignore files in the CVS repository subdirs
2962 to make a "cvs update" really silent.
2963 [Ralf S. Engelschall]
2965 *) Recompiled the error-definition header files and added
2966 missing symbols to the Win32 linker tables.
2967 [Ralf S. Engelschall]
2969 *) Cleaned up the top-level documents;

2983 [Ralf S. Engelschall]
2985 *) Added various platform portability fixes.
2988 *) The Genesis of the OpenSSL rpject:
2989 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
2990 Young and Tim J. Hudson created while they were working for C2Net until
2992 [The OpenSSL Project]
2995 Changes between 0.9.0b and 0.9.1b [not released]
2997 *) Updated a few CA certificates under certs/
3000 *) Changed some BIGNUM api stuff.
3003 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
3004 DGUX x86, Linux Alpha, etc.
3007 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
3008 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
3012 *) Add -strparse option to asn1pars program which parses nested
3014 [Dr Stephen Henson <shenson@bigfoot.com>]
3016 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
3019 *) DSA fix for "ca" program.
3022 *) Added "-genkey" option to "dsaparam" program.
3025 *) Added RIPE MD160 (rmd160) message digest.
3028 *) Added -a (all) option to "ssleay version" command.
3031 *) Added PLATFORM define which is the id given to Configure.
3034 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
3037 *) Extended the ASN.1 parser routines.
3040 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
3043 *) Added a BN_CTX to the BN library.
3046 *) Fixed the weak key values in DES library
3049 *) Changed API in EVP library for cipher aliases.
3052 *) Added support for RC2/64bit cipher.
3055 *) Converted the lhash library to the crypto/mem.c functions.
3058 *) Added more recognized ASN.1 object ids.
3061 *) Added more RSA padding checks for SSL/TLS.
3064 *) Added BIO proxy/filter functionality.
3067 *) Added extra_certs to SSL_CTX which can be used
3068 send extra CA certificates to the client in the CA cert chain sending
3069 process. It can be configured with SSL_CTX_add_extra_chain_cert().
3072 *) Now Fortezza is denied in the authentication phase because
3073 this is key exchange mechanism is not supported by SSLeay at all.
3076 *) Additional PKCS1 checks.
3079 *) Support the string "TLSv1" for all TLS v1 ciphers.
3082 *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
3083 ex_data index of the SSL context in the X509_STORE_CTX ex_data.
3086 *) Fixed a few memory leaks.
3089 *) Fixed various code and comment typos.
3092 *) A minor bug in ssl/s3_clnt.c where there would always be 4 0
3093 bytes sent in the client random.
