5 Changes between 0.9.4 and 0.9.5 [xx XXX 1999]
7 *) Add a few manpages for some of the openssl commands.
10 *) Fix the -revoke option in ca. It was freeing up memory twice,
11 leaking and not finding already revoked certificates.
14 *) Extensive changes to support certificate auxiliary information.
15 This involves the use of X509_CERT_AUX structure and X509_AUX
16 functions. An X509_AUX function such as PEM_read_X509_AUX()
17 can still read in a certificate file in the usual way but it
18 will also read in any additional "auxiliary information". By
19 doing things this way a fair degree of compatability can be
20 retained: existing certificates can have this information added
21 using the new 'x509' options.
23 Current auxiliary information includes an "alias" and some trust
24 settings. The trust settings will ultimately be used in enhanced
25 certificate chain verification routines: currently a certificate
26 can only be trusted if it is self signed and then it is trusted
30 *) Fix assembler for Alpha (tested only on DEC OSF not Linux or *BSD). The
31 problem was that one of the replacement routines had not been working since
32 SSLeay releases. For now the offending routine has been replaced with
33 non-optimised assembler. Even so, this now gives around 95% performance
34 improvement for 1024 bit RSA signs.
37 *) Hack to fix PKCS#7 decryption when used with some unorthodox RC2
38 handling. Most clients have the effective key size in bits equal to
39 the key length in bits: so a 40 bit RC2 key uses a 40 bit (5 byte) key.
40 A few however don't do this and instead use the size of the decrypted key
41 to determine the RC2 key length and the AlgorithmIdentifier to determine
42 the effective key length. In this case the effective key lenth can still
43 be 40 bits but the key length can be 168 bits for example. This is fixed
44 by manually forcing an RC2 key into the EVP_PKEY structure because the
45 EVP code can't currently handle unusual RC2 key sizes: it always assumes
46 the key length and effective key length are equal.
49 *) Add a bunch of functions that should simplify the creation of
50 X509_NAME structures. Now you should be able to do:
51 X509_NAME_add_entry_by_txt(nm, "CN", MBSTRING_ASC, "Steve", -1, -1, 0);
52 and have it automatically work out the correct field type and fill in
53 the structures. The more adventurous can try:
54 X509_NAME_add_entry_by_txt(nm, field, MBSTRING_UTF8, str, -1, -1, 0);
55 and it will (hopefully) work out the correct multibyte encoding.
58 *) Change the 'req' utility to use the new field handling and multibyte
59 copy routines. Before the DN field creation was handled in an ad hoc
60 way in req, ca, and x509 which was rather broken and didn't support
61 BMPStrings or UTF8Strings. Since some software doesn't implement
62 BMPStrings or UTF8Strings yet, they can be enabled using the config file
63 using the dirstring_type option. See the new comment in the default
64 openssl.cnf for more info.
67 *) Make crypto/rand/md_rand.c more robust:
68 - Assure unique random numbers after fork().
69 - Make sure that concurrent threads access the global counter and
70 md serializably so that we never lose entropy in them
71 or use exactly the same state in multiple threads.
72 Access to the large state is not always serializable because
73 the additional locking could be a performance killer, and
74 md should be large enough anyway.
77 *) New file apps/app_rand.c with commonly needed functionality
78 for handling the random seed file.
80 Use the random seed file in some applications that previously did not:
82 dsaparam -genkey (which also ignored its `-rand' option),
86 Except on systems with /dev/urandom, it is crucial to have a random
87 seed file at least for key creation, DSA signing, and for DH exchanges;
88 for RSA signatures we could do without one.
90 gendh and gendsa (unlike genrsa) used to read only the first byte
91 of each file listed in the `-rand' option. The function as previously
92 found in genrsa is now in app_rand.c and is used by all programs
96 *) In RAND_write_file, use mode 0600 for creating files;
97 don't just chmod when it may be too late.
100 *) Report an error from X509_STORE_load_locations
101 when X509_LOOKUP_load_file or X509_LOOKUP_add_dir failed.
104 *) New function ASN1_mbstring_copy() this copies a string in either
105 ASCII, Unicode, Universal (4 bytes per character) or UTF8 format
106 into an ASN1_STRING type. A mask of permissible types is passed
107 and it chooses the "minimal" type to use or an error if not type
111 *) Add function equivalents to the various macros in asn1.h. The old
112 macros are retained with an M_ prefix. Code inside the library can
113 use the M_ macros. External code (including the openssl utility)
114 should *NOT* in order to be "shared library friendly".
117 *) Add various functions that can check a certificate's extensions
118 to see if it usable for various purposes such as SSL client,
119 server or S/MIME and CAs of these types. This is currently
120 VERY EXPERIMENTAL but will ultimately be used for certificate chain
121 verification. Also added a -purpose flag to x509 utility to
122 print out all the purposes.
125 *) Add a CRYPTO_EX_DATA to X509 certificate structure and associated
129 *) New X509V3_{X509,CRL,REVOKED}_get_d2i() functions. These will search
130 for, obtain and decode and extension and obtain its critical flag.
131 This allows all the necessary extension code to be handled in a
132 single function call.
135 *) RC4 tune-up featuring 30-40% performance improvement on most RISC
136 platforms. See crypto/rc4/rc4_enc.c for further details.
139 *) New -noout option to asn1parse. This causes no output to be produced
140 its main use is when combined with -strparse and -out to extract data
141 from a file (which may not be in ASN.1 format).
144 *) Fix for pkcs12 program. It was hashing an invalid certificate pointer
145 when producing the local key id.
146 [Richard Levitte <levitte@stacken.kth.se>]
148 *) New option -dhparam in s_server. This allows a DH parameter file to be
149 stated explicitly. If it is not stated then it tries the first server
150 certificate file. The previous behaviour hard coded the filename
154 *) Add -pubin and -pubout options to the rsa and dsa commands. These allow
155 a public key to be input or output. For example:
156 openssl rsa -in key.pem -pubout -out pubkey.pem
157 Also added necessary DSA public key functions to handle this.
160 *) Fix so PKCS7_dataVerify() doesn't crash if no certificates are contained
161 in the message. This was handled by allowing
162 X509_find_by_issuer_and_serial() to tolerate a NULL passed to it.
163 [Steve Henson, reported by Sampo Kellomaki <sampo@mail.neuronio.pt>]
165 *) Fix for bug in d2i_ASN1_bytes(): other ASN1 functions add an extra null
166 to the end of the strings whereas this didn't. This would cause problems
167 if strings read with d2i_ASN1_bytes() were later modified.
168 [Steve Henson, reported by Arne Ansper <arne@ats.cyber.ee>]
170 *) Fix for base64 decode bug. When a base64 bio reads only one line of
171 data and it contains EOF it will end up returning an error. This is
172 caused by input 46 bytes long. The cause is due to the way base64
173 BIOs find the start of base64 encoded data. They do this by trying a
174 trial decode on each line until they find one that works. When they
175 do a flag is set and it starts again knowing it can pass all the
176 data directly through the decoder. Unfortunately it doesn't reset
177 the context it uses. This means that if EOF is reached an attempt
178 is made to pass two EOFs through the context and this causes the
179 resulting error. This can also cause other problems as well. As is
180 usual with these problems it takes *ages* to find and the fix is
181 trivial: move one line.
182 [Steve Henson, reported by ian@uns.ns.ac.yu (Ivan Nejgebauer) ]
184 *) Ugly workaround to get s_client and s_server working under Windows. The
185 old code wouldn't work because it needed to select() on sockets and the
186 tty (for keypresses and to see if data could be written). Win32 only
187 supports select() on sockets so we select() with a 1s timeout on the
188 sockets and then see if any characters are waiting to be read, if none
189 are present then we retry, we also assume we can always write data to
190 the tty. This isn't nice because the code then blocks until we've
191 received a complete line of data and it is effectively polling the
192 keyboard at 1s intervals: however it's quite a bit better than not
193 working at all :-) A dedicated Windows application might handle this
194 with an event loop for example.
197 *) Enhance RSA_METHOD structure. Now there are two extra methods, rsa_sign
198 and rsa_verify. When the RSA_FLAGS_SIGN_VER option is set these functions
199 will be called when RSA_sign() and RSA_verify() are used. This is useful
200 if rsa_pub_dec() and rsa_priv_enc() equivalents are not available.
201 For this to work properly RSA_public_decrypt() and RSA_private_encrypt()
202 should *not* be used: RSA_sign() and RSA_verify() must be used instead.
203 This necessitated the support of an extra signature type NID_md5_sha1
204 for SSL signatures and modifications to the SSL library to use it instead
205 of calling RSA_public_decrypt() and RSA_private_encrypt().
208 *) Add new -verify -CAfile and -CApath options to the crl program, these
209 will lookup a CRL issuers certificate and verify the signature in a
210 similar way to the verify program. Tidy up the crl program so it
211 no longer acesses structures directly. Make the ASN1 CRL parsing a bit
212 less strict. It will now permit CRL extensions even if it is not
213 a V2 CRL: this will allow it to tolerate some broken CRLs.
216 *) Initialize all non-automatic variables each time one of the openssl
217 sub-programs is started (this is necessary as they may be started
218 multiple times from the "OpenSSL>" prompt).
219 [Lennart Bang, Bodo Moeller]
221 *) Preliminary compilation option RSA_NULL which disables RSA crypto without
222 removing all other RSA functionality (this is what NO_RSA does). This
223 is so (for example) those in the US can disable those operations covered
224 by the RSA patent while allowing storage and parsing of RSA keys and RSA
228 *) Non-copying interface to BIO pairs.
229 (still largely untested)
232 *) New function ANS1_tag2str() to convert an ASN1 tag to a descriptive
233 ASCII string. This was handled independently in various places before.
236 *) New functions UTF8_getc() and UTF8_putc() that parse and generate
237 UTF8 strings a character at a time.
240 *) Use client_version from client hello to select the protocol
241 (s23_srvr.c) and for RSA client key exchange verification
242 (s3_srvr.c), as required by the SSL 3.0/TLS 1.0 specifications.
245 *) Add various utility functions to handle SPKACs, these were previously
246 handled by poking round in the structure internals. Added new function
247 NETSCAPE_SPKI_print() to print out SPKAC and a new utility 'spkac' to
248 print, verify and generate SPKACs. Based on an original idea from
249 Massimiliano Pala <madwolf@comune.modena.it> but extensively modified.
252 *) RIPEMD160 is operational on all platforms and is back in 'make test'.
255 *) Allow the config file extension section to be overwritten on the
256 command line. Based on an original idea from Massimiliano Pala
257 <madwolf@comune.modena.it>. The new option is called -extensions
258 and can be applied to ca, req and x509. Also -reqexts to override
259 the request extensions in req and -crlexts to override the crl extensions
263 *) Add new feature to the SPKAC handling in ca. Now you can include
264 the same field multiple times by preceding it by "XXXX." for example:
267 this is the same syntax as used in the req config file.
270 *) Allow certificate extensions to be added to certificate requests. These
271 are specified in a 'req_extensions' option of the req section of the
272 config file. They can be printed out with the -text option to req but
273 are otherwise ignored at present.
276 *) Fix a horrible bug in enc_read() in crypto/evp/bio_enc.c: if the first
277 data read consists of only the final block it would not decrypted because
278 EVP_CipherUpdate() would correctly report zero bytes had been decrypted.
279 A misplaced 'break' also meant the decrypted final block might not be
280 copied until the next read.
283 *) Initial support for DH_METHOD. Again based on RSA_METHOD. Also added
284 a few extra parameters to the DH structure: these will be useful if
285 for example we want the value of 'q' or implement X9.42 DH.
288 *) Initial support for DSA_METHOD. This is based on the RSA_METHOD and
289 provides hooks that allow the default DSA functions or functions on a
290 "per key" basis to be replaced. This allows hardware acceleration and
291 hardware key storage to be handled without major modification to the
292 library. Also added low level modexp hooks and CRYPTO_EX structure and
293 associated functions.
296 *) Add a new flag to memory BIOs, BIO_FLAG_MEM_RDONLY. This marks the BIO
297 as "read only": it can't be written to and the buffer it points to will
298 not be freed. Reading from a read only BIO is much more efficient than
299 a normal memory BIO. This was added because there are several times when
300 an area of memory needs to be read from a BIO. The previous method was
301 to create a memory BIO and write the data to it, this results in two
302 copies of the data and an O(n^2) reading algorithm. There is a new
303 function BIO_new_mem_buf() which creates a read only memory BIO from
304 an area of memory. Also modified the PKCS#7 routines to use read only
308 *) Bugfix: ssl23_get_client_hello did not work properly when called in
309 state SSL23_ST_SR_CLNT_HELLO_B, i.e. when the first 7 bytes of
310 a SSLv2-compatible client hello for SSLv3 or TLSv1 could be read,
311 but a retry condition occured while trying to read the rest.
314 *) The PKCS7_ENC_CONTENT_new() function was setting the content type as
315 NID_pkcs7_encrypted by default: this was wrong since this should almost
316 always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle
317 the encrypted data type: this is a more sensible place to put it and it
318 allows the PKCS#12 code to be tidied up that duplicated this
322 *) Changed obj_dat.pl script so it takes its input and output files on
323 the command line. This should avoid shell escape redirection problems
327 *) Initial support for certificate extension requests, these are included
328 in things like Xenroll certificate requests. Included functions to allow
329 extensions to be obtained and added.
332 *) -crlf option to s_client and s_server for sending newlines as
333 CRLF (as required by many protocols).
336 Changes between 0.9.3a and 0.9.4 [09 Aug 1999]
338 *) Install libRSAglue.a when OpenSSL is built with RSAref.
339 [Ralf S. Engelschall]
341 *) A few more ``#ifndef NO_FP_API / #endif'' pairs for consistency.
342 [Andrija Antonijevic <TheAntony2@bigfoot.com>]
344 *) Fix -startdate and -enddate (which was missing) arguments to 'ca'
348 *) New function DSA_dup_DH, which duplicates DSA parameters/keys as
349 DH parameters/keys (q is lost during that conversion, but the resulting
350 DH parameters contain its length).
352 For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is
353 much faster than DH_generate_parameters (which creates parameters
354 where p = 2*q + 1), and also the smaller q makes DH computations
355 much more efficient (160-bit exponentiation instead of 1024-bit
356 exponentiation); so this provides a convenient way to support DHE
357 ciphersuites in SSL/TLS servers (see ssl/ssltest.c). It is of
358 utter importance to use
359 SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
361 SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
362 when such DH parameters are used, because otherwise small subgroup
363 attacks may become possible!
366 *) Avoid memory leak in i2d_DHparams.
369 *) Allow the -k option to be used more than once in the enc program:
370 this allows the same encrypted message to be read by multiple recipients.
373 *) New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts
374 an ASN1_OBJECT to a text string. If the "no_name" parameter is set then
375 it will always use the numerical form of the OID, even if it has a short
379 *) Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp
380 method only got called if p,q,dmp1,dmq1,iqmp components were present,
381 otherwise bn_mod_exp was called. In the case of hardware keys for example
382 no private key components need be present and it might store extra data
383 in the RSA structure, which cannot be accessed from bn_mod_exp.
384 By setting RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for
385 private key operations.
388 *) Added support for SPARC Linux.
391 *) pem_password_cb function type incompatibly changed from
392 typedef int pem_password_cb(char *buf, int size, int rwflag);
394 ....(char *buf, int size, int rwflag, void *userdata);
395 so that applications can pass data to their callbacks:
396 The PEM[_ASN1]_{read,write}... functions and macros now take an
397 additional void * argument, which is just handed through whenever
398 the password callback is called.
399 [Damien Miller <dmiller@ilogic.com.au>; tiny changes by Bodo Moeller]
401 New function SSL_CTX_set_default_passwd_cb_userdata.
403 Compatibility note: As many C implementations push function arguments
404 onto the stack in reverse order, the new library version is likely to
405 interoperate with programs that have been compiled with the old
406 pem_password_cb definition (PEM_whatever takes some data that
407 happens to be on the stack as its last argument, and the callback
408 just ignores this garbage); but there is no guarantee whatsoever that
411 *) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=...
412 (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused
413 problems not only on Windows, but also on some Unix platforms.
414 To avoid problematic command lines, these definitions are now in an
415 auto-generated file crypto/buildinf.h (created by crypto/Makefile.ssl
416 for standard "make" builds, by util/mk1mf.pl for "mk1mf" builds).
419 *) MIPS III/IV assembler module is reimplemented.
422 *) More DES library cleanups: remove references to srand/rand and
423 delete an unused file.
426 *) Add support for the the free Netwide assembler (NASM) under Win32,
427 since not many people have MASM (ml) and it can be hard to obtain.
428 This is currently experimental but it seems to work OK and pass all
429 the tests. Check out INSTALL.W32 for info.
432 *) Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections
433 without temporary keys kept an extra copy of the server key,
434 and connections with temporary keys did not free everything in case
438 *) New function RSA_check_key and new openssl rsa option -check
439 for verifying the consistency of RSA keys.
440 [Ulf Moeller, Bodo Moeller]
442 *) Various changes to make Win32 compile work:
443 1. Casts to avoid "loss of data" warnings in p5_crpt2.c
444 2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned
445 comparison" warnings.
446 3. Add sk_<TYPE>_sort to DEF file generator and do make update.
449 *) Add a debugging option to PKCS#5 v2 key generation function: when
450 you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and
451 derived keys are printed to stderr.
454 *) Copy the flags in ASN1_STRING_dup().
455 [Roman E. Pavlov <pre@mo.msk.ru>]
457 *) The x509 application mishandled signing requests containing DSA
458 keys when the signing key was also DSA and the parameters didn't match.
460 It was supposed to omit the parameters when they matched the signing key:
461 the verifying software was then supposed to automatically use the CA's
462 parameters if they were absent from the end user certificate.
464 Omitting parameters is no longer recommended. The test was also
465 the wrong way round! This was probably due to unusual behaviour in
466 EVP_cmp_parameters() which returns 1 if the parameters match.
467 This meant that parameters were omitted when they *didn't* match and
468 the certificate was useless. Certificates signed with 'ca' didn't have
470 [Steve Henson, reported by Doug Erickson <Doug.Erickson@Part.NET>]
472 *) Memory leak checking (-DCRYPTO_MDEBUG) had some problems.
473 The interface is as follows:
475 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(),
476 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop();
477 "off" is now the default.
478 The library internally uses
479 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(),
480 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on()
481 to disable memory-checking temporarily.
483 Some inconsistent states that previously were possible (and were
484 even the default) are now avoided.
486 -DCRYPTO_MDEBUG_TIME is new and additionally stores the current time
487 with each memory chunk allocated; this is occasionally more helpful
488 than just having a counter.
490 -DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID.
492 -DCRYPTO_MDEBUG_ALL enables all of the above, plus any future
496 *) Introduce "mode" for SSL structures (with defaults in SSL_CTX),
497 which largely parallels "options", but is for changing API behaviour,
498 whereas "options" are about protocol behaviour.
499 Initial "mode" flags are:
501 SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when
502 a single record has been written.
503 SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write
504 retries use the same buffer location.
505 (But all of the contents must be
509 *) Bugfix: SSL_set_mode ignored its parameter, only SSL_CTX_set_mode
512 *) Fix problems with no-hmac etc.
513 [Ulf Möller, pointed out by Brian Wellington <bwelling@tislabs.com>]
515 *) New functions RSA_get_default_method(), RSA_set_method() and
516 RSA_get_method(). These allows replacement of RSA_METHODs without having
517 to mess around with the internals of an RSA structure.
520 *) Fix memory leaks in DSA_do_sign and DSA_is_prime.
521 Also really enable memory leak checks in openssl.c and in some
523 [Chad C. Mulligan, Bodo Moeller]
525 *) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess
526 up the length of negative integers. This has now been simplified to just
527 store the length when it is first determined and use it later, rather
528 than trying to keep track of where data is copied and updating it to
530 [Steve Henson, reported by Brien Wheeler
531 <bwheeler@authentica-security.com>]
533 *) Add a new function PKCS7_signatureVerify. This allows the verification
534 of a PKCS#7 signature but with the signing certificate passed to the
535 function itself. This contrasts with PKCS7_dataVerify which assumes the
536 certificate is present in the PKCS#7 structure. This isn't always the
537 case: certificates can be omitted from a PKCS#7 structure and be
538 distributed by "out of band" means (such as a certificate database).
541 *) Complete the PEM_* macros with DECLARE_PEM versions to replace the
542 function prototypes in pem.h, also change util/mkdef.pl to add the
543 necessary function names.
546 *) mk1mf.pl (used by Windows builds) did not properly read the
547 options set by Configure in the top level Makefile, and Configure
548 was not even able to write more than one option correctly.
549 Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended.
552 *) New functions CONF_load_bio() and CONF_load_fp() to allow a config
553 file to be loaded from a BIO or FILE pointer. The BIO version will
554 for example allow memory BIOs to contain config info.
557 *) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS.
558 Whoever hopes to achieve shared-library compatibility across versions
559 must use this, not the compile-time macro.
560 (Exercise 0.9.4: Which is the minimum library version required by
562 Note: All this applies only to multi-threaded programs, others don't
566 *) Add missing case to s3_clnt.c state machine -- one of the new SSL tests
567 through a BIO pair triggered the default case, i.e.
568 SSLerr(...,SSL_R_UNKNOWN_STATE).
571 *) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications
572 can use the SSL library even if none of the specific BIOs is
576 *) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value
577 for the encoded length.
578 [Jeon KyoungHo <khjeon@sds.samsung.co.kr>]
580 *) Add initial documentation of the X509V3 functions.
583 *) Add a new pair of functions PEM_write_PKCS8PrivateKey() and
584 PEM_write_bio_PKCS8PrivateKey() that are equivalent to
585 PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more
586 secure PKCS#8 private key format with a high iteration count.
589 *) Fix determination of Perl interpreter: A perl or perl5
590 _directory_ in $PATH was also accepted as the interpreter.
591 [Ralf S. Engelschall]
593 *) Fix demos/sign/sign.c: well there wasn't anything strictly speaking
594 wrong with it but it was very old and did things like calling
595 PEM_ASN1_read() directly and used MD5 for the hash not to mention some
599 *) Fix demos/selfsign.c: it used obsolete and deleted functions, changed
600 to use the new extension code.
603 *) Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c
604 with macros. This should make it easier to change their form, add extra
605 arguments etc. Fix a few PEM prototypes which didn't have cipher as a
609 *) Add to configuration table a new entry that can specify an alternative
610 name for unistd.h (for pre-POSIX systems); we need this for NeXTstep,
611 according to Mark Crispin <MRC@Panda.COM>.
615 *) DES CBC did not update the IV. Weird.
618 des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does.
619 Changing the behaviour of the former might break existing programs --
620 where IV updating is needed, des_ncbc_encrypt can be used.
623 *) When bntest is run from "make test" it drives bc to check its
624 calculations, as well as internally checking them. If an internal check
625 fails, it needs to cause bc to give a non-zero result or make test carries
626 on without noticing the failure. Fixed.
629 *) DES library cleanups.
632 *) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be
633 used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit
634 ciphers. NOTE: although the key derivation function has been verified
635 against some published test vectors it has not been extensively tested
636 yet. Added a -v2 "cipher" option to pkcs8 application to allow the use
640 *) Instead of "mkdir -p", which is not fully portable, use new
641 Perl script "util/mkdir-p.pl".
644 *) Rewrite the way password based encryption (PBE) is handled. It used to
645 assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter
646 structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms
647 but doesn't apply to PKCS#5 v2.0 where it can be something else. Now
648 the 'parameter' field of the AlgorithmIdentifier is passed to the
649 underlying key generation function so it must do its own ASN1 parsing.
650 This has also changed the EVP_PBE_CipherInit() function which now has a
651 'parameter' argument instead of literal salt and iteration count values
652 and the function EVP_PBE_ALGOR_CipherInit() has been deleted.
655 *) Support for PKCS#5 v1.5 compatible password based encryption algorithms
656 and PKCS#8 functionality. New 'pkcs8' application linked to openssl.
657 Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE
658 KEY" because this clashed with PKCS#8 unencrypted string. Since this
659 value was just used as a "magic string" and not used directly its
660 value doesn't matter.
663 *) Introduce some semblance of const correctness to BN. Shame C doesn't
667 *) "linux-sparc64" configuration (ultrapenguin).
668 [Ray Miller <ray.miller@oucs.ox.ac.uk>]
669 "linux-sparc" configuration.
670 [Christian Forster <fo@hawo.stw.uni-erlangen.de>]
672 *) config now generates no-xxx options for missing ciphers.
675 *) Support the EBCDIC character set (work in progress).
676 File ebcdic.c not yet included because it has a different license.
677 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
679 *) Support BS2000/OSD-POSIX.
680 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
682 *) Make callbacks for key generation use void * instead of char *.
685 *) Make S/MIME samples compile (not yet tested).
688 *) Additional typesafe stacks.
691 *) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x).
695 Changes between 0.9.3 and 0.9.3a [29 May 1999]
697 *) New configuration variant "sco5-gcc".
699 *) Updated some demos.
700 [Sean O Riordain, Wade Scholine]
702 *) Add missing BIO_free at exit of pkcs12 application.
705 *) Fix memory leak in conf.c.
708 *) Updates for Win32 to assembler version of MD5.
711 *) Set #! path to perl in apps/der_chop to where we found it
712 instead of using a fixed path.
715 *) SHA library changes for irix64-mips4-cc.
718 *) Improvements for VMS support.
722 Changes between 0.9.2b and 0.9.3 [24 May 1999]
724 *) Bignum library bug fix. IRIX 6 passes "make test" now!
725 This also avoids the problems with SC4.2 and unpatched SC5.
726 [Andy Polyakov <appro@fy.chalmers.se>]
728 *) New functions sk_num, sk_value and sk_set to replace the previous macros.
729 These are required because of the typesafe stack would otherwise break
730 existing code. If old code used a structure member which used to be STACK
731 and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with
732 sk_num or sk_value it would produce an error because the num, data members
733 are not present in STACK_OF. Now it just produces a warning. sk_set
734 replaces the old method of assigning a value to sk_value
735 (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code
736 that does this will no longer work (and should use sk_set instead) but
737 this could be regarded as a "questionable" behaviour anyway.
740 *) Fix most of the other PKCS#7 bugs. The "experimental" code can now
741 correctly handle encrypted S/MIME data.
744 *) Change type of various DES function arguments from des_cblock
745 (which means, in function argument declarations, pointer to char)
746 to des_cblock * (meaning pointer to array with 8 char elements),
747 which allows the compiler to do more typechecking; it was like
748 that back in SSLeay, but with lots of ugly casts.
750 Introduce new type const_des_cblock.
753 *) Reorganise the PKCS#7 library and get rid of some of the more obvious
754 problems: find RecipientInfo structure that matches recipient certificate
755 and initialise the ASN1 structures properly based on passed cipher.
758 *) Belatedly make the BN tests actually check the results.
761 *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion
762 to and from BNs: it was completely broken. New compilation option
763 NEG_PUBKEY_BUG to allow for some broken certificates that encode public
764 key elements as negative integers.
767 *) Reorganize and speed up MD5.
768 [Andy Polyakov <appro@fy.chalmers.se>]
771 [Richard Levitte <richard@levitte.org>]
773 *) New option -out to asn1parse to allow the parsed structure to be
774 output to a file. This is most useful when combined with the -strparse
775 option to examine the output of things like OCTET STRINGS.
778 *) Make SSL library a little more fool-proof by not requiring any longer
779 that SSL_set_{accept,connect}_state be called before
780 SSL_{accept,connect} may be used (SSL_set_..._state is omitted
781 in many applications because usually everything *appeared* to work as
782 intended anyway -- now it really works as intended).
785 *) Move openssl.cnf out of lib/.
788 *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall
789 -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
790 -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+
791 [Ralf S. Engelschall]
793 *) Various fixes to the EVP and PKCS#7 code. It may now be able to
794 handle PKCS#7 enveloped data properly.
795 [Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve]
797 *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
798 copying pointers. The cert_st handling is changed by this in
799 various ways (and thus what used to be known as ctx->default_cert
800 is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
801 any longer when s->cert does not give us what we need).
802 ssl_cert_instantiate becomes obsolete by this change.
803 As soon as we've got the new code right (possibly it already is?),
804 we have solved a couple of bugs of the earlier code where s->cert
805 was used as if it could not have been shared with other SSL structures.
807 Note that using the SSL API in certain dirty ways now will result
808 in different behaviour than observed with earlier library versions:
809 Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
810 does not influence s as it used to.
812 In order to clean up things more thoroughly, inside SSL_SESSION
813 we don't use CERT any longer, but a new structure SESS_CERT
814 that holds per-session data (if available); currently, this is
815 the peer's certificate chain and, for clients, the server's certificate
816 and temporary key. CERT holds only those values that can have
817 meaningful defaults in an SSL_CTX.
820 *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure
821 from the internal representation. Various PKCS#7 fixes: remove some
822 evil casts and set the enc_dig_alg field properly based on the signing
826 *) Allow PKCS#12 password to be set from the command line or the
827 environment. Let 'ca' get its config file name from the environment
828 variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req'
832 *) Allow certificate policies extension to use an IA5STRING for the
833 organization field. This is contrary to the PKIX definition but
834 VeriSign uses it and IE5 only recognises this form. Document 'x509'
838 *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic,
839 without disallowing inline assembler and the like for non-pedantic builds.
842 *) Support Borland C++ builder.
843 [Janez Jere <jj@void.si>, modified by Ulf Möller]
848 *) SHA-1 cleanups and performance enhancements.
849 [Andy Polyakov <appro@fy.chalmers.se>]
851 *) Sparc v8plus assembler for the bignum library.
852 [Andy Polyakov <appro@fy.chalmers.se>]
854 *) Accept any -xxx and +xxx compiler options in Configure.
857 *) Update HPUX configuration.
860 *) Add missing sk_<type>_unshift() function to safestack.h
861 [Ralf S. Engelschall]
863 *) New function SSL_CTX_use_certificate_chain_file that sets the
864 "extra_cert"s in addition to the certificate. (This makes sense
865 only for "PEM" format files, as chains as a whole are not
869 *) Support verify_depth from the SSL API.
870 x509_vfy.c had what can be considered an off-by-one-error:
871 Its depth (which was not part of the external interface)
872 was actually counting the number of certificates in a chain;
873 now it really counts the depth.
876 *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used
877 instead of X509err, which often resulted in confusing error
878 messages since the error codes are not globally unique
879 (e.g. an alleged error in ssl3_accept when a certificate
880 didn't match the private key).
882 *) New function SSL_CTX_set_session_id_context that allows to set a default
883 value (so that you don't need SSL_set_session_id_context for each
884 connection using the SSL_CTX).
887 *) OAEP decoding bug fix.
890 *) Support INSTALL_PREFIX for package builders, as proposed by
894 *) New Configure options "threads" and "no-threads". For systems
895 where the proper compiler options are known (currently Solaris
896 and Linux), "threads" is the default.
899 *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
902 *) Install various scripts to $(OPENSSLDIR)/misc, not to
903 $(INSTALLTOP)/bin -- they shouldn't clutter directories
904 such as /usr/local/bin.
907 *) "make linux-shared" to build shared libraries.
908 [Niels Poppe <niels@netbox.org>]
910 *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
913 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
914 extension adding in x509 utility.
917 *) Remove NOPROTO sections and error code comments.
920 *) Partial rewrite of the DEF file generator to now parse the ANSI
924 *) New Configure options --prefix=DIR and --openssldir=DIR.
927 *) Complete rewrite of the error code script(s). It is all now handled
928 by one script at the top level which handles error code gathering,
929 header rewriting and C source file generation. It should be much better
930 than the old method: it now uses a modified version of Ulf's parser to
931 read the ANSI prototypes in all header files (thus the old K&R definitions
932 aren't needed for error creation any more) and do a better job of
933 translating function codes into names. The old 'ASN1 error code imbedded
934 in a comment' is no longer necessary and it doesn't use .err files which
935 have now been deleted. Also the error code call doesn't have to appear all
936 on one line (which resulted in some large lines...).
939 *) Change #include filenames from <foo.h> to <openssl/foo.h>.
942 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
943 0 (which usually indicates a closed connection), but continue reading.
946 *) Fix some race conditions.
949 *) Add support for CRL distribution points extension. Add Certificate
950 Policies and CRL distribution points documentation.
953 *) Move the autogenerated header file parts to crypto/opensslconf.h.
956 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
957 8 of keying material. Merlin has also confirmed interop with this fix
958 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
959 [Merlin Hughes <merlin@baltimore.ie>]
961 *) Fix lots of warnings.
962 [Richard Levitte <levitte@stacken.kth.se>]
964 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
965 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
966 [Richard Levitte <levitte@stacken.kth.se>]
968 *) Fix problems with sizeof(long) == 8.
969 [Andy Polyakov <appro@fy.chalmers.se>]
971 *) Change functions to ANSI C.
974 *) Fix typos in error codes.
975 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
977 *) Remove defunct assembler files from Configure.
980 *) SPARC v8 assembler BIGNUM implementation.
981 [Andy Polyakov <appro@fy.chalmers.se>]
983 *) Support for Certificate Policies extension: both print and set.
984 Various additions to support the r2i method this uses.
987 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
988 return a const string when you are expecting an allocated buffer.
991 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
992 types DirectoryString and DisplayText.
995 *) Add code to allow r2i extensions to access the configuration database,
996 add an LHASH database driver and add several ctx helper functions.
999 *) Fix an evil bug in bn_expand2() which caused various BN functions to
1000 fail when they extended the size of a BIGNUM.
1003 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
1004 support typesafe stack.
1007 *) Fix typo in SSL_[gs]et_options().
1008 [Nils Frostberg <nils@medcom.se>]
1010 *) Delete various functions and files that belonged to the (now obsolete)
1011 old X509V3 handling code.
1014 *) New Configure option "rsaref".
1017 *) Don't auto-generate pem.h.
1020 *) Introduce type-safe ASN.1 SETs.
1023 *) Convert various additional casted stacks to type-safe STACK_OF() variants.
1024 [Ben Laurie, Ralf S. Engelschall, Steve Henson]
1026 *) Introduce type-safe STACKs. This will almost certainly break lots of code
1027 that links with OpenSSL (well at least cause lots of warnings), but fear
1028 not: the conversion is trivial, and it eliminates loads of evil casts. A
1029 few STACKed things have been converted already. Feel free to convert more.
1030 In the fullness of time, I'll do away with the STACK type altogether.
1033 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
1034 specified in <certfile> by updating the entry in the index.txt file.
1035 This way one no longer has to edit the index.txt file manually for
1036 revoking a certificate. The -revoke option does the gory details now.
1037 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
1039 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
1040 `-text' option at all and this way the `-noout -text' combination was
1041 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
1042 [Ralf S. Engelschall]
1044 *) Make sure a corresponding plain text error message exists for the
1045 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
1046 verify callback function determined that a certificate was revoked.
1047 [Ralf S. Engelschall]
1049 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
1050 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
1051 all available cipers including rc5, which was forgotten until now.
1052 In order to let the testing shell script know which algorithms
1053 are available, a new (up to now undocumented) command
1054 "openssl list-cipher-commands" is used.
1057 *) Bugfix: s_client occasionally would sleep in select() when
1058 it should have checked SSL_pending() first.
1061 *) New functions DSA_do_sign and DSA_do_verify to provide access to
1062 the raw DSA values prior to ASN.1 encoding.
1065 *) Tweaks to Configure
1066 [Niels Poppe <niels@netbox.org>]
1068 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
1072 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
1075 *) New config option to avoid instructions that are illegal on the 80386.
1076 The default code is faster, but requires at least a 486.
1079 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
1080 SSL2_SERVER_VERSION (not used at all) macros, which are now the
1081 same as SSL2_VERSION anyway.
1084 *) New "-showcerts" option for s_client.
1087 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
1088 application. Various cleanups and fixes.
1091 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
1092 modify error routines to work internally. Add error codes and PBE init
1093 to library startup routines.
1096 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
1097 packing functions to asn1 and evp. Changed function names and error
1098 codes along the way.
1101 *) PKCS12 integration: and so it begins... First of several patches to
1102 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
1103 objects to objects.h
1106 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
1107 and display support for Thawte strong extranet extension.
1110 *) Add LinuxPPC support.
1111 [Jeff Dubrule <igor@pobox.org>]
1113 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
1114 bn_div_words in alpha.s.
1115 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
1117 *) Make sure the RSA OAEP test is skipped under -DRSAref because
1118 OAEP isn't supported when OpenSSL is built with RSAref.
1119 [Ulf Moeller <ulf@fitug.de>]
1121 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
1122 so they no longer are missing under -DNOPROTO.
1123 [Soren S. Jorvang <soren@t.dk>]
1126 Changes between 0.9.1c and 0.9.2b [22 Mar 1999]
1128 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
1129 doesn't work when the session is reused. Coming soon!
1132 *) Fix a security hole, that allows sessions to be reused in the wrong
1133 context thus bypassing client cert protection! All software that uses
1134 client certs and session caches in multiple contexts NEEDS PATCHING to
1135 allow session reuse! A fuller solution is in the works.
1136 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
1138 *) Some more source tree cleanups (removed obsolete files
1139 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
1140 permission on "config" script to be executable) and a fix for the INSTALL
1142 [Ulf Moeller <ulf@fitug.de>]
1144 *) Remove some legacy and erroneous uses of malloc, free instead of
1146 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
1148 *) Make rsa_oaep_test return non-zero on error.
1149 [Ulf Moeller <ulf@fitug.de>]
1151 *) Add support for native Solaris shared libraries. Configure
1152 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
1153 if someone would make that last step automatic.
1154 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
1156 *) ctx_size was not built with the right compiler during "make links". Fixed.
1159 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
1160 except NULL ciphers". This means the default cipher list will no longer
1161 enable NULL ciphers. They need to be specifically enabled e.g. with
1162 the string "DEFAULT:eNULL".
1165 *) Fix to RSA private encryption routines: if p < q then it would
1166 occasionally produce an invalid result. This will only happen with
1167 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
1170 *) Be less restrictive and allow also `perl util/perlpath.pl
1171 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
1172 because this way one can also use an interpreter named `perl5' (which is
1173 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
1174 installed as `perl').
1175 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
1177 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
1178 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
1180 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
1181 advapi32.lib to Win32 build and change the pem test comparision
1182 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
1183 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
1184 and crypto/des/ede_cbcm_enc.c.
1187 *) DES quad checksum was broken on big-endian architectures. Fixed.
1190 *) Comment out two functions in bio.h that aren't implemented. Fix up the
1191 Win32 test batch file so it (might) work again. The Win32 test batch file
1192 is horrible: I feel ill....
1195 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
1196 in e_os.h. Audit of header files to check ANSI and non ANSI
1197 sections: 10 functions were absent from non ANSI section and not exported
1198 from Windows DLLs. Fixed up libeay.num for new functions.
1201 *) Make `openssl version' output lines consistent.
1202 [Ralf S. Engelschall]
1204 *) Fix Win32 symbol export lists for BIO functions: Added
1205 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
1206 to ms/libeay{16,32}.def.
1207 [Ralf S. Engelschall]
1209 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
1210 fine under Unix and passes some trivial tests I've now added. But the
1211 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
1212 added to make sure no one expects that this stuff really works in the
1213 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
1214 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
1216 [Ralf S. Engelschall]
1218 *) Fix the generation of two part addresses in perl.
1219 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
1221 *) Add config entry for Linux on MIPS.
1222 [John Tobey <jtobey@channel1.com>]
1224 *) Make links whenever Configure is run, unless we are on Windoze.
1227 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
1228 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
1232 *) Add a useful kludge to allow package maintainers to specify compiler and
1233 other platforms details on the command line without having to patch the
1234 Configure script everytime: One now can use ``perl Configure
1235 <id>:<details>'', i.e. platform ids are allowed to have details appended
1236 to them (seperated by colons). This is treated as there would be a static
1237 pre-configured entry in Configure's %table under key <id> with value
1238 <details> and ``perl Configure <id>'' is called. So, when you want to
1239 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
1240 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
1241 now, which overrides the FreeBSD-elf entry on-the-fly.
1242 [Ralf S. Engelschall]
1244 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
1247 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
1248 on the `perl Configure ...' command line. This way one can compile
1249 OpenSSL libraries with Position Independent Code (PIC) which is needed
1250 for linking it into DSOs.
1251 [Ralf S. Engelschall]
1253 *) Remarkably, export ciphers were totally broken and no-one had noticed!
1257 *) Cleaned up the LICENSE document: The official contact for any license
1258 questions now is the OpenSSL core team under openssl-core@openssl.org.
1259 And add a paragraph about the dual-license situation to make sure people
1260 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
1261 to the OpenSSL toolkit.
1262 [Ralf S. Engelschall]
1264 *) General source tree makefile cleanups: Made `making xxx in yyy...'
1265 display consistent in the source tree and replaced `/bin/rm' by `rm'.
1266 Additonally cleaned up the `make links' target: Remove unnecessary
1267 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
1268 to speed processing and no longer clutter the display with confusing
1269 stuff. Instead only the actually done links are displayed.
1270 [Ralf S. Engelschall]
1272 *) Permit null encryption ciphersuites, used for authentication only. It used
1273 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
1274 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
1278 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
1279 signed attributes when verifying signatures (this would break them),
1280 the detached data encoding was wrong and public keys obtained using
1281 X509_get_pubkey() weren't freed.
1284 *) Add text documentation for the BUFFER functions. Also added a work around
1285 to a Win95 console bug. This was triggered by the password read stuff: the
1286 last character typed gets carried over to the next fread(). If you were
1287 generating a new cert request using 'req' for example then the last
1288 character of the passphrase would be CR which would then enter the first
1292 *) Added the new `Includes OpenSSL Cryptography Software' button as
1293 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
1294 button and can be used by applications based on OpenSSL to show the
1295 relationship to the OpenSSL project.
1296 [Ralf S. Engelschall]
1298 *) Remove confusing variables in function signatures in files
1299 ssl/ssl_lib.c and ssl/ssl.h.
1300 [Lennart Bong <lob@kulthea.stacken.kth.se>]
1302 *) Don't install bss_file.c under PREFIX/include/
1303 [Lennart Bong <lob@kulthea.stacken.kth.se>]
1305 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
1306 functions that return function pointers and has support for NT specific
1307 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
1308 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
1309 unsigned to signed types: this was killing the Win32 compile.
1312 *) Add new certificate file to stack functions,
1313 SSL_add_dir_cert_subjects_to_stack() and
1314 SSL_add_file_cert_subjects_to_stack(). These largely supplant
1315 SSL_load_client_CA_file(), and can be used to add multiple certs easily
1316 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
1317 This means that Apache-SSL and similar packages don't have to mess around
1318 to add as many CAs as they want to the preferred list.
1321 *) Experiment with doxygen documentation. Currently only partially applied to
1323 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
1324 openssl.doxy as the configuration file.
1327 *) Get rid of remaining C++-style comments which strict C compilers hate.
1328 [Ralf S. Engelschall, pointed out by Carlos Amengual]
1330 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
1331 compiled in by default: it has problems with large keys.
1334 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
1335 DH private keys and/or callback functions which directly correspond to
1336 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
1337 is needed for applications which have to configure certificates on a
1338 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
1340 For the RSA certificate situation is makes no difference, but
1341 for the DSA certificate situation this fixes the "no shared cipher"
1342 problem where the OpenSSL cipher selection procedure failed because the
1343 temporary keys were not overtaken from the context and the API provided
1344 no way to reconfigure them.
1345 The new functions now let applications reconfigure the stuff and they
1346 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
1347 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
1348 non-public-API function ssl_cert_instantiate() is used as a helper
1349 function and also to reduce code redundancy inside ssl_rsa.c.
1350 [Ralf S. Engelschall]
1352 *) Move s_server -dcert and -dkey options out of the undocumented feature
1353 area because they are useful for the DSA situation and should be
1354 recognized by the users.
1355 [Ralf S. Engelschall]
1357 *) Fix the cipher decision scheme for export ciphers: the export bits are
1358 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
1359 SSL_EXP_MASK. So, the original variable has to be used instead of the
1360 already masked variable.
1361 [Richard Levitte <levitte@stacken.kth.se>]
1363 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
1364 [Richard Levitte <levitte@stacken.kth.se>]
1366 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
1367 from `int' to `unsigned int' because it's a length and initialized by
1368 EVP_DigestFinal() which expects an `unsigned int *'.
1369 [Richard Levitte <levitte@stacken.kth.se>]
1371 *) Don't hard-code path to Perl interpreter on shebang line of Configure
1372 script. Instead use the usual Shell->Perl transition trick.
1373 [Ralf S. Engelschall]
1375 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
1376 (in addition to RSA certificates) to match the behaviour of `openssl dsa
1377 -noout -modulus' as it's already the case for `openssl rsa -noout
1378 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
1379 currently the public key is printed (a decision which was already done by
1380 `openssl dsa -modulus' in the past) which serves a similar purpose.
1381 Additionally the NO_RSA no longer completely removes the whole -modulus
1382 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
1384 [Ralf S. Engelschall]
1386 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
1387 BIO. See the source (crypto/evp/bio_ok.c) for more info.
1388 [Arne Ansper <arne@ats.cyber.ee>]
1390 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
1391 to be added. Now both 'req' and 'ca' can use new objects defined in the
1395 *) Add cool BIO that does syslog (or event log on NT).
1396 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
1398 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
1399 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
1400 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
1401 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
1404 *) Add preliminary config info for new extension code.
1407 *) Make RSA_NO_PADDING really use no padding.
1408 [Ulf Moeller <ulf@fitug.de>]
1410 *) Generate errors when private/public key check is done.
1413 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
1414 for some CRL extensions and new objects added.
1417 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
1418 key usage extension and fuller support for authority key id.
1421 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
1422 padding method for RSA, which is recommended for new applications in PKCS
1423 #1 v2.0 (RFC 2437, October 1998).
1424 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
1425 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
1426 against Bleichbacher's attack on RSA.
1427 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
1430 *) Updates to the new SSL compression code
1431 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
1433 *) Fix so that the version number in the master secret, when passed
1434 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
1435 (because the server will not accept higher), that the version number
1436 is 0x03,0x01, not 0x03,0x00
1437 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
1439 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
1440 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
1441 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
1444 *) Support for RAW extensions where an arbitrary extension can be
1445 created by including its DER encoding. See apps/openssl.cnf for
1449 *) Make sure latest Perl versions don't interpret some generated C array
1450 code as Perl array code in the crypto/err/err_genc.pl script.
1451 [Lars Weber <3weber@informatik.uni-hamburg.de>]
1453 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
1454 not many people have the assembler. Various Win32 compilation fixes and
1455 update to the INSTALL.W32 file with (hopefully) more accurate Win32
1459 *) Modify configure script 'Configure' to automatically create crypto/date.h
1460 file under Win32 and also build pem.h from pem.org. New script
1461 util/mkfiles.pl to create the MINFO file on environments that can't do a
1462 'make files': perl util/mkfiles.pl >MINFO should work.
1465 *) Major rework of DES function declarations, in the pursuit of correctness
1466 and purity. As a result, many evil casts evaporated, and some weirdness,
1467 too. You may find this causes warnings in your code. Zapping your evil
1468 casts will probably fix them. Mostly.
1471 *) Fix for a typo in asn1.h. Bug fix to object creation script
1472 obj_dat.pl. It considered a zero in an object definition to mean
1473 "end of object": none of the objects in objects.h have any zeros
1474 so it wasn't spotted.
1475 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
1477 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
1478 Masking (CBCM). In the absence of test vectors, the best I have been able
1479 to do is check that the decrypt undoes the encrypt, so far. Send me test
1480 vectors if you have them.
1483 *) Correct calculation of key length for export ciphers (too much space was
1484 allocated for null ciphers). This has not been tested!
1487 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
1488 message is now correct (it understands "crypto" and "ssl" on its
1489 command line). There is also now an "update" option. This will update
1490 the util/ssleay.num and util/libeay.num files with any new functions.
1492 perl util/mkdef.pl crypto ssl update
1493 it will update them.
1496 *) Overhauled the Perl interface (perl/*):
1497 - ported BN stuff to OpenSSL's different BN library
1498 - made the perl/ source tree CVS-aware
1499 - renamed the package from SSLeay to OpenSSL (the files still contain
1500 their history because I've copied them in the repository)
1501 - removed obsolete files (the test scripts will be replaced
1502 by better Test::Harness variants in the future)
1503 [Ralf S. Engelschall]
1505 *) First cut for a very conservative source tree cleanup:
1506 1. merge various obsolete readme texts into doc/ssleay.txt
1507 where we collect the old documents and readme texts.
1508 2. remove the first part of files where I'm already sure that we no
1509 longer need them because of three reasons: either they are just temporary
1510 files which were left by Eric or they are preserved original files where
1511 I've verified that the diff is also available in the CVS via "cvs diff
1512 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
1513 the crypto/md/ stuff).
1514 [Ralf S. Engelschall]
1516 *) More extension code. Incomplete support for subject and issuer alt
1517 name, issuer and authority key id. Change the i2v function parameters
1518 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
1519 what that's for :-) Fix to ASN1 macro which messed up
1520 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
1523 *) Preliminary support for ENUMERATED type. This is largely copied from the
1527 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
1528 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
1530 *) Make sure `make rehash' target really finds the `openssl' program.
1531 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
1533 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
1534 like to hear about it if this slows down other processors.
1537 *) Add CygWin32 platform information to Configure script.
1538 [Alan Batie <batie@aahz.jf.intel.com>]
1540 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
1541 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
1543 *) New program nseq to manipulate netscape certificate sequences
1546 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
1550 *) Fixes to BN code. Previously the default was to define BN_RECURSION
1551 but the BN code had some problems that would cause failures when
1552 doing certificate verification and some other functions.
1553 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
1555 *) Add ASN1 and PEM code to support netscape certificate sequences.
1558 *) Add ASN1 and PEM code to support netscape certificate sequences.
1561 *) Add several PKIX and private extended key usage OIDs.
1564 *) Modify the 'ca' program to handle the new extension code. Modify
1565 openssl.cnf for new extension format, add comments.
1568 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
1569 and add a sample to openssl.cnf so req -x509 now adds appropriate
1573 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
1574 error code, add initial support to X509_print() and x509 application.
1577 *) Takes a deep breath and start addding X509 V3 extension support code. Add
1578 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
1579 stuff is currently isolated and isn't even compiled yet.
1582 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
1583 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
1584 Removed the versions check from X509 routines when loading extensions:
1585 this allows certain broken certificates that don't set the version
1586 properly to be processed.
1589 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
1590 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
1591 can still be regenerated with "make depend".
1594 *) Spelling mistake in C version of CAST-128.
1595 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
1597 *) Changes to the error generation code. The perl script err-code.pl
1598 now reads in the old error codes and retains the old numbers, only
1599 adding new ones if necessary. It also only changes the .err files if new
1600 codes are added. The makefiles have been modified to only insert errors
1601 when needed (to avoid needlessly modifying header files). This is done
1602 by only inserting errors if the .err file is newer than the auto generated
1603 C file. To rebuild all the error codes from scratch (the old behaviour)
1604 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
1605 or delete all the .err files.
1608 *) CAST-128 was incorrectly implemented for short keys. The C version has
1609 been fixed, but is untested. The assembler versions are also fixed, but
1610 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
1611 to regenerate it if needed.
1612 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
1613 Hagino <itojun@kame.net>]
1615 *) File was opened incorrectly in randfile.c.
1616 [Ulf Möller <ulf@fitug.de>]
1618 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
1619 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
1620 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
1621 al: it's just almost always a UTCTime. Note this patch adds new error
1622 codes so do a "make errors" if there are problems.
1625 *) Correct Linux 1 recognition in config.
1626 [Ulf Möller <ulf@fitug.de>]
1628 *) Remove pointless MD5 hash when using DSA keys in ca.
1629 [Anonymous <nobody@replay.com>]
1631 *) Generate an error if given an empty string as a cert directory. Also
1632 generate an error if handed NULL (previously returned 0 to indicate an
1633 error, but didn't set one).
1634 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
1636 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
1639 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
1640 parameters. This was causing a warning which killed off the Win32 compile.
1643 *) Remove C++ style comments from crypto/bn/bn_local.h.
1644 [Neil Costigan <neil.costigan@celocom.com>]
1646 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
1647 based on a text string, looking up short and long names and finally
1648 "dot" format. The "dot" format stuff didn't work. Added new function
1649 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
1650 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
1651 OID is not part of the table.
1654 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
1655 X509_LOOKUP_by_alias().
1658 *) Sort openssl functions by name.
1661 *) Get the gendsa program working (hopefully) and add it to app list. Remove
1662 encryption from sample DSA keys (in case anyone is interested the password
1666 *) Make _all_ *_free functions accept a NULL pointer.
1667 [Frans Heymans <fheymans@isaserver.be>]
1669 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
1671 [Anonymous <nobody@replay.com>]
1673 *) s_server should send the CAfile as acceptable CAs, not its own cert.
1674 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
1676 *) Don't blow it for numeric -newkey arguments to apps/req.
1677 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
1679 *) Temp key "for export" tests were wrong in s3_srvr.c.
1680 [Anonymous <nobody@replay.com>]
1682 *) Add prototype for temp key callback functions
1683 SSL_CTX_set_tmp_{rsa,dh}_callback().
1686 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
1687 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
1690 *) X509_name_add_entry() freed the wrong thing after an error.
1691 [Arne Ansper <arne@ats.cyber.ee>]
1693 *) rsa_eay.c would attempt to free a NULL context.
1694 [Arne Ansper <arne@ats.cyber.ee>]
1696 *) BIO_s_socket() had a broken should_retry() on Windoze.
1697 [Arne Ansper <arne@ats.cyber.ee>]
1699 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
1700 [Arne Ansper <arne@ats.cyber.ee>]
1702 *) Make sure the already existing X509_STORE->depth variable is initialized
1703 in X509_STORE_new(), but document the fact that this variable is still
1704 unused in the certificate verification process.
1705 [Ralf S. Engelschall]
1707 *) Fix the various library and apps files to free up pkeys obtained from
1708 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
1711 *) Fix reference counting in X509_PUBKEY_get(). This makes
1712 demos/maurice/example2.c work, amongst others, probably.
1713 [Steve Henson and Ben Laurie]
1715 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
1716 `openssl' and second, the shortcut symlinks for the `openssl <command>'
1717 are no longer created. This way we have a single and consistent command
1718 line interface `openssl <command>', similar to `cvs <command>'.
1719 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
1721 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
1722 BIT STRING wrapper always have zero unused bits.
1725 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
1728 *) Make the top-level INSTALL documentation easier to understand.
1731 *) Makefiles updated to exit if an error occurs in a sub-directory
1732 make (including if user presses ^C) [Paul Sutton]
1734 *) Make Montgomery context stuff explicit in RSA data structure.
1737 *) Fix build order of pem and err to allow for generated pem.h.
1740 *) Fix renumbering bug in X509_NAME_delete_entry().
1743 *) Enhanced the err-ins.pl script so it makes the error library number
1744 global and can add a library name. This is needed for external ASN1 and
1745 other error libraries.
1748 *) Fixed sk_insert which never worked properly.
1751 *) Fix ASN1 macros so they can handle indefinite length construted
1752 EXPLICIT tags. Some non standard certificates use these: they can now
1756 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
1757 into a single doc/ssleay.txt bundle. This way the information is still
1758 preserved but no longer messes up this directory. Now it's new room for
1759 the new set of documenation files.
1760 [Ralf S. Engelschall]
1762 *) SETs were incorrectly DER encoded. This was a major pain, because they
1763 shared code with SEQUENCEs, which aren't coded the same. This means that
1764 almost everything to do with SETs or SEQUENCEs has either changed name or
1765 number of arguments.
1766 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
1768 *) Fix test data to work with the above.
1771 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
1772 was already fixed by Eric for 0.9.1 it seems.
1773 [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
1775 *) Autodetect FreeBSD3.
1778 *) Fix various bugs in Configure. This affects the following platforms:
1782 unixware-2.0-pentium
1786 *) Eliminate generated files from CVS. Reorder tests to regenerate files
1787 before they are needed.
1790 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
1794 Changes between 0.9.1b and 0.9.1c [23-Dec-1998]
1796 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
1797 changed SSLeay to OpenSSL in version strings.
1798 [Ralf S. Engelschall]
1800 *) Some fixups to the top-level documents.
1803 *) Fixed the nasty bug where rsaref.h was not found under compile-time
1804 because the symlink to include/ was missing.
1805 [Ralf S. Engelschall]
1807 *) Incorporated the popular no-RSA/DSA-only patches
1808 which allow to compile a RSA-free SSLeay.
1809 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
1811 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
1812 when "ssleay" is still not found.
1813 [Ralf S. Engelschall]
1815 *) Added more platforms to Configure: Cray T3E, HPUX 11,
1816 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
1818 *) Updated the README file.
1819 [Ralf S. Engelschall]
1821 *) Added various .cvsignore files in the CVS repository subdirs
1822 to make a "cvs update" really silent.
1823 [Ralf S. Engelschall]

1842 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
1843 [Ralf S. Engelschall]
1845 *) Added various platform portability fixes.
1848 *) The Genesis of the OpenSSL rpject:
1849 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
1850 Young and Tim J. Hudson created while they were working for C2Net until
1852 [The OpenSSL Project]
1855 Changes between 0.9.0b and 0.9.1b [not released]
1857 *) Updated a few CA certificates under certs/
1860 *) Changed some BIGNUM api stuff.
1863 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
1864 DGUX x86, Linux Alpha, etc.
1867 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
1868 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
1872 *) Add -strparse option to asn1pars program which parses nested
1874 [Dr Stephen Henson <shenson@bigfoot.com>]
1876 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
1879 *) DSA fix for "ca" program.
1882 *) Added "-genkey" option to "dsaparam" program.
1885 *) Added RIPE MD160 (rmd160) message digest.
1888 *) Added -a (all) option to "ssleay version" command.
1891 *) Added PLATFORM define which is the id given to Configure.
1894 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
1897 *) Extended the ASN.1 parser routines.
1900 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
1903 *) Added a BN_CTX to the BN library.
1906 *) Fixed the weak key values in DES library
1909 *) Changed API in EVP library for cipher aliases.
1912 *) Added support for RC2/64bit cipher.
1915 *) Converted the lhash library to the crypto/mem.c functions.
1918 *) Added more recognized ASN.1 object ids.
1921 *) Added more RSA padding checks for SSL/TLS.
1924 *) Added BIO proxy/filter functionality.
1927 *) Added extra_certs to SSL_CTX which can be used
1928 send extra CA certificates to the client in the CA cert chain sending
1929 process. It can be configured with SSL_CTX_add_extra_chain_cert().
1932 *) Now Fortezza is denied in the authentication phase because
1933 this is key exchange mechanism is not supported by SSLeay at all.
1936 *) Additional PKCS1 checks.
1939 *) Support the string "TLSv1" for all TLS v1 ciphers.
1942 *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
1943 ex_data index of the SSL context in the X509_STORE_CTX ex_data.
1946 *) Fixed a few memory leaks.
1949 *) Fixed various code and comment typos.
1952 *) A minor bug in ssl/s3_clnt.c where there would always be 4 0
1953 bytes sent in the client random.
