5 Changes between 0.9.4 and 0.9.5 [xx XXX 1999]
7 *) Add new feature to the SPKAC handling in ca. Now you can include
8 the same field multiple times by preceding it by "XXXX." for example:
11 this is the same syntax as used in the req config file.
14 *) Allow certificate extensions to be added to certificate requests. These
15 are specified in a 'req_extensions' option of the req section of the
16 config file. They can be printed out with the -text option to req but
17 are otherwise ignored at present.
20 *) Fix a horrible bug in enc_read() in crypto/evp/bio_enc.c: if the first data
21 read consists of only the final block it would not decrypted because
22 EVP_CipherUpdate() would correctly report zero bytes had been decrypted.
23 A misplaced 'break' also meant the decrypted final block might not be
24 copied until the next read.
27 *) Initial support for DH_METHOD. Again based on RSA_METHOD. Also added
28 a few extra parameters to the DH structure: these will be useful if
29 for example we want the value of 'q' or implement X9.42 DH.
32 *) Initial support for DSA_METHOD. This is based on the RSA_METHOD and
33 provides hooks that allow the default DSA functions or functions on a
34 "per key" basis to be replaced. This allows hardware acceleration and
35 hardware key storage to be handled without major modification to the
36 library. Also added low level modexp hooks and CRYPTO_EX structure and
40 *) Add a new flag to memory BIOs, BIO_FLAG_MEM_RDONLY. This marks the BIO
41 as "read only": it can't be written to and the buffer it points to will
42 not be freed. Reading from a read only BIO is much more efficient than
43 a normal memory BIO. This was added because there are several times when
44 an area of memory needs to be read from a BIO. The previous method was
45 to create a memory BIO and write the data to it, this results in two
46 copies of the data and an O(n^2) reading algorithm. There is a new
47 function BIO_new_mem_buf() which creates a read only memory BIO from
48 an area of memory. Also modified the PKCS#7 routines to use read only
52 *) Bugfix: ssl23_get_client_hello did not work properly when called in
53 state SSL23_ST_SR_CLNT_HELLO_B, i.e. when the first 7 bytes of
54 a SSLv2-compatible client hello for SSLv3 or TLSv1 could be read,
55 but a retry condition occured while trying to read the rest.
58 *) The PKCS7_ENC_CONTENT_new() function was setting the content type as
59 NID_pkcs7_encrypted by default: this was wrong since this should almost
60 always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle
61 the encrypted data type: this is a more sensible place to put it and it
62 allows the PKCS#12 code to be tidied up that duplicated this
66 *) Changed obj_dat.pl script so it takes its input and output files on
67 the command line. This should avoid shell escape redirection problems
71 *) Initial support for certificate extension requests, these are included
72 in things like Xenroll certificate requests. Included functions to allow
73 extensions to be obtained and added.
76 *) -crlf option to s_client and s_server for sending newlines as
77 CRLF (as required by many protocols).
80 Changes between 0.9.3a and 0.9.4 [09 Aug 1999]
82 *) Install libRSAglue.a when OpenSSL is built with RSAref.
85 *) A few more ``#ifndef NO_FP_API / #endif'' pairs for consistency.
86 [Andrija Antonijevic <TheAntony2@bigfoot.com>]
88 *) Fix -startdate and -enddate (which was missing) arguments to 'ca'
92 *) New function DSA_dup_DH, which duplicates DSA parameters/keys as
93 DH parameters/keys (q is lost during that conversion, but the resulting
94 DH parameters contain its length).
96 For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is
97 much faster than DH_generate_parameters (which creates parameters
98 where p = 2*q + 1), and also the smaller q makes DH computations
99 much more efficient (160-bit exponentiation instead of 1024-bit
100 exponentiation); so this provides a convenient way to support DHE
101 ciphersuites in SSL/TLS servers (see ssl/ssltest.c). It is of
102 utter importance to use
103 SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
105 SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
106 when such DH parameters are used, because otherwise small subgroup
107 attacks may become possible!
110 *) Avoid memory leak in i2d_DHparams.
113 *) Allow the -k option to be used more than once in the enc program:
114 this allows the same encrypted message to be read by multiple recipients.
117 *) New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts
118 an ASN1_OBJECT to a text string. If the "no_name" parameter is set then
119 it will always use the numerical form of the OID, even if it has a short
123 *) Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp
124 method only got called if p,q,dmp1,dmq1,iqmp components were present,
125 otherwise bn_mod_exp was called. In the case of hardware keys for example
126 no private key components need be present and it might store extra data
127 in the RSA structure, which cannot be accessed from bn_mod_exp. By setting
128 RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for private key
132 *) Added support for SPARC Linux.
135 *) pem_password_cb function type incompatibly changed from
136 typedef int pem_password_cb(char *buf, int size, int rwflag);
138 ....(char *buf, int size, int rwflag, void *userdata);
139 so that applications can pass data to their callbacks:
140 The PEM[_ASN1]_{read,write}... functions and macros now take an
141 additional void * argument, which is just handed through whenever
142 the password callback is called.
143 [Damien Miller <dmiller@ilogic.com.au>, with tiny changes by Bodo Moeller]
145 New function SSL_CTX_set_default_passwd_cb_userdata.
147 Compatibility note: As many C implementations push function arguments
148 onto the stack in reverse order, the new library version is likely to
149 interoperate with programs that have been compiled with the old
150 pem_password_cb definition (PEM_whatever takes some data that
151 happens to be on the stack as its last argument, and the callback
152 just ignores this garbage); but there is no guarantee whatsoever that
155 *) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=...
156 (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused
157 problems not only on Windows, but also on some Unix platforms.
158 To avoid problematic command lines, these definitions are now in an
159 auto-generated file crypto/buildinf.h (created by crypto/Makefile.ssl
160 for standard "make" builds, by util/mk1mf.pl for "mk1mf" builds).
163 *) MIPS III/IV assembler module is reimplemented.
166 *) More DES library cleanups: remove references to srand/rand and
167 delete an unused file.
170 *) Add support for the the free Netwide assembler (NASM) under Win32,
171 since not many people have MASM (ml) and it can be hard to obtain.
172 This is currently experimental but it seems to work OK and pass all
173 the tests. Check out INSTALL.W32 for info.
176 *) Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections
177 without temporary keys kept an extra copy of the server key,
178 and connections with temporary keys did not free everything in case
182 *) New function RSA_check_key and new openssl rsa option -check
183 for verifying the consistency of RSA keys.
184 [Ulf Moeller, Bodo Moeller]
186 *) Various changes to make Win32 compile work:
187 1. Casts to avoid "loss of data" warnings in p5_crpt2.c
188 2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned
189 comparison" warnings.
190 3. Add sk_<TYPE>_sort to DEF file generator and do make update.
193 *) Add a debugging option to PKCS#5 v2 key generation function: when
194 you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and
195 derived keys are printed to stderr.
198 *) Copy the flags in ASN1_STRING_dup().
199 [Roman E. Pavlov <pre@mo.msk.ru>]
201 *) The x509 application mishandled signing requests containing DSA
202 keys when the signing key was also DSA and the parameters didn't match.
204 It was supposed to omit the parameters when they matched the signing key:
205 the verifying software was then supposed to automatically use the CA's
206 parameters if they were absent from the end user certificate.
208 Omitting parameters is no longer recommended. The test was also
209 the wrong way round! This was probably due to unusual behaviour in
210 EVP_cmp_parameters() which returns 1 if the parameters match.
211 This meant that parameters were omitted when they *didn't* match and
212 the certificate was useless. Certificates signed with 'ca' didn't have
214 [Steve Henson, reported by Doug Erickson <Doug.Erickson@Part.NET>]
216 *) Memory leak checking (-DCRYPTO_MDEBUG) had some problems.
217 The interface is as follows:
219 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(),
220 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop();
221 "off" is now the default.
222 The library internally uses
223 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(),
224 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on()
225 to disable memory-checking temporarily.
227 Some inconsistent states that previously were possible (and were
228 even the default) are now avoided.
230 -DCRYPTO_MDEBUG_TIME is new and additionally stores the current time
231 with each memory chunk allocated; this is occasionally more helpful
232 than just having a counter.
234 -DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID.
236 -DCRYPTO_MDEBUG_ALL enables all of the above, plus any future
240 *) Introduce "mode" for SSL structures (with defaults in SSL_CTX),
241 which largely parallels "options", but is for changing API behaviour,
242 whereas "options" are about protocol behaviour.
243 Initial "mode" flags are:
245 SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when
246 a single record has been written.
247 SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write
248 retries use the same buffer location.
249 (But all of the contents must be
253 *) Bugfix: SSL_set_mode ignored its parameter, only SSL_CTX_set_mode
256 *) Fix problems with no-hmac etc.
257 [Ulf Möller, pointed out by Brian Wellington <bwelling@tislabs.com>]
259 *) New functions RSA_get_default_method(), RSA_set_method() and
260 RSA_get_method(). These allows replacement of RSA_METHODs without having
261 to mess around with the internals of an RSA structure.
264 *) Fix memory leaks in DSA_do_sign and DSA_is_prime.
265 Also really enable memory leak checks in openssl.c and in some
267 [Chad C. Mulligan, Bodo Moeller]
269 *) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess
270 up the length of negative integers. This has now been simplified to just
271 store the length when it is first determined and use it later, rather
272 than trying to keep track of where data is copied and updating it to
274 [Steve Henson, reported by Brien Wheeler
275 <bwheeler@authentica-security.com>]
277 *) Add a new function PKCS7_signatureVerify. This allows the verification
278 of a PKCS#7 signature but with the signing certificate passed to the
279 function itself. This contrasts with PKCS7_dataVerify which assumes the
280 certificate is present in the PKCS#7 structure. This isn't always the
281 case: certificates can be omitted from a PKCS#7 structure and be
282 distributed by "out of band" means (such as a certificate database).
285 *) Complete the PEM_* macros with DECLARE_PEM versions to replace the
286 function prototypes in pem.h, also change util/mkdef.pl to add the
287 necessary function names.
290 *) mk1mf.pl (used by Windows builds) did not properly read the
291 options set by Configure in the top level Makefile, and Configure
292 was not even able to write more than one option correctly.
293 Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended.
296 *) New functions CONF_load_bio() and CONF_load_fp() to allow a config
297 file to be loaded from a BIO or FILE pointer. The BIO version will
298 for example allow memory BIOs to contain config info.
301 *) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS.
302 Whoever hopes to achieve shared-library compatibility across versions
303 must use this, not the compile-time macro.
304 (Exercise 0.9.4: Which is the minimum library version required by
306 Note: All this applies only to multi-threaded programs, others don't
310 *) Add missing case to s3_clnt.c state machine -- one of the new SSL tests
311 through a BIO pair triggered the default case, i.e.
312 SSLerr(...,SSL_R_UNKNOWN_STATE).
315 *) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications
316 can use the SSL library even if none of the specific BIOs is
320 *) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value
321 for the encoded length.
322 [Jeon KyoungHo <khjeon@sds.samsung.co.kr>]
324 *) Add initial documentation of the X509V3 functions.
327 *) Add a new pair of functions PEM_write_PKCS8PrivateKey() and
328 PEM_write_bio_PKCS8PrivateKey() that are equivalent to
329 PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more
330 secure PKCS#8 private key format with a high iteration count.
333 *) Fix determination of Perl interpreter: A perl or perl5
334 _directory_ in $PATH was also accepted as the interpreter.
335 [Ralf S. Engelschall]
337 *) Fix demos/sign/sign.c: well there wasn't anything strictly speaking
338 wrong with it but it was very old and did things like calling
339 PEM_ASN1_read() directly and used MD5 for the hash not to mention some
343 *) Fix demos/selfsign.c: it used obsolete and deleted functions, changed
344 to use the new extension code.
347 *) Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c
348 with macros. This should make it easier to change their form, add extra
349 arguments etc. Fix a few PEM prototypes which didn't have cipher as a
353 *) Add to configuration table a new entry that can specify an alternative
354 name for unistd.h (for pre-POSIX systems); we need this for NeXTstep,
355 according to Mark Crispin <MRC@Panda.COM>.
359 *) DES CBC did not update the IV. Weird.
362 des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does.
363 Changing the behaviour of the former might break existing programs --
364 where IV updating is needed, des_ncbc_encrypt can be used.
367 *) When bntest is run from "make test" it drives bc to check its
368 calculations, as well as internally checking them. If an internal check
369 fails, it needs to cause bc to give a non-zero result or make test carries
370 on without noticing the failure. Fixed.
373 *) DES library cleanups.
376 *) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be
377 used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit
378 ciphers. NOTE: although the key derivation function has been verified
379 against some published test vectors it has not been extensively tested
380 yet. Added a -v2 "cipher" option to pkcs8 application to allow the use
384 *) Instead of "mkdir -p", which is not fully portable, use new
385 Perl script "util/mkdir-p.pl".
388 *) Rewrite the way password based encryption (PBE) is handled. It used to
389 assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter
390 structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms
391 but doesn't apply to PKCS#5 v2.0 where it can be something else. Now
392 the 'parameter' field of the AlgorithmIdentifier is passed to the
393 underlying key generation function so it must do its own ASN1 parsing.
394 This has also changed the EVP_PBE_CipherInit() function which now has a
395 'parameter' argument instead of literal salt and iteration count values
396 and the function EVP_PBE_ALGOR_CipherInit() has been deleted.
399 *) Support for PKCS#5 v1.5 compatible password based encryption algorithms
400 and PKCS#8 functionality. New 'pkcs8' application linked to openssl.
401 Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE
402 KEY" because this clashed with PKCS#8 unencrypted string. Since this
403 value was just used as a "magic string" and not used directly its
404 value doesn't matter.
407 *) Introduce some semblance of const correctness to BN. Shame C doesn't
411 *) "linux-sparc64" configuration (ultrapenguin).
412 [Ray Miller <ray.miller@oucs.ox.ac.uk>]
413 "linux-sparc" configuration.
414 [Christian Forster <fo@hawo.stw.uni-erlangen.de>]
416 *) config now generates no-xxx options for missing ciphers.
419 *) Support the EBCDIC character set (work in progress).
420 File ebcdic.c not yet included because it has a different license.
421 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
423 *) Support BS2000/OSD-POSIX.
424 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
426 *) Make callbacks for key generation use void * instead of char *.
429 *) Make S/MIME samples compile (not yet tested).
432 *) Additional typesafe stacks.
435 *) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x).
439 Changes between 0.9.3 and 0.9.3a [29 May 1999]
441 *) New configuration variant "sco5-gcc".
443 *) Updated some demos.
444 [Sean O Riordain, Wade Scholine]
446 *) Add missing BIO_free at exit of pkcs12 application.
449 *) Fix memory leak in conf.c.
452 *) Updates for Win32 to assembler version of MD5.
455 *) Set #! path to perl in apps/der_chop to where we found it
456 instead of using a fixed path.
459 *) SHA library changes for irix64-mips4-cc.
462 *) Improvements for VMS support.
466 Changes between 0.9.2b and 0.9.3 [24 May 1999]
468 *) Bignum library bug fix. IRIX 6 passes "make test" now!
469 This also avoids the problems with SC4.2 and unpatched SC5.
470 [Andy Polyakov <appro@fy.chalmers.se>]
472 *) New functions sk_num, sk_value and sk_set to replace the previous macros.
473 These are required because of the typesafe stack would otherwise break
474 existing code. If old code used a structure member which used to be STACK
475 and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with
476 sk_num or sk_value it would produce an error because the num, data members
477 are not present in STACK_OF. Now it just produces a warning. sk_set
478 replaces the old method of assigning a value to sk_value
479 (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code
480 that does this will no longer work (and should use sk_set instead) but
481 this could be regarded as a "questionable" behaviour anyway.
484 *) Fix most of the other PKCS#7 bugs. The "experimental" code can now
485 correctly handle encrypted S/MIME data.
488 *) Change type of various DES function arguments from des_cblock
489 (which means, in function argument declarations, pointer to char)
490 to des_cblock * (meaning pointer to array with 8 char elements),
491 which allows the compiler to do more typechecking; it was like
492 that back in SSLeay, but with lots of ugly casts.
494 Introduce new type const_des_cblock.
497 *) Reorganise the PKCS#7 library and get rid of some of the more obvious
498 problems: find RecipientInfo structure that matches recipient certificate
499 and initialise the ASN1 structures properly based on passed cipher.
502 *) Belatedly make the BN tests actually check the results.
505 *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion
506 to and from BNs: it was completely broken. New compilation option
507 NEG_PUBKEY_BUG to allow for some broken certificates that encode public
508 key elements as negative integers.
511 *) Reorganize and speed up MD5.
512 [Andy Polyakov <appro@fy.chalmers.se>]
515 [Richard Levitte <richard@levitte.org>]
517 *) New option -out to asn1parse to allow the parsed structure to be
518 output to a file. This is most useful when combined with the -strparse
519 option to examine the output of things like OCTET STRINGS.
522 *) Make SSL library a little more fool-proof by not requiring any longer
523 that SSL_set_{accept,connect}_state be called before
524 SSL_{accept,connect} may be used (SSL_set_..._state is omitted
525 in many applications because usually everything *appeared* to work as
526 intended anyway -- now it really works as intended).
529 *) Move openssl.cnf out of lib/.
532 *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall
533 -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
534 -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+
535 [Ralf S. Engelschall]
537 *) Various fixes to the EVP and PKCS#7 code. It may now be able to
538 handle PKCS#7 enveloped data properly.
539 [Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve]
541 *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
542 copying pointers. The cert_st handling is changed by this in
543 various ways (and thus what used to be known as ctx->default_cert
544 is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
545 any longer when s->cert does not give us what we need).
546 ssl_cert_instantiate becomes obsolete by this change.
547 As soon as we've got the new code right (possibly it already is?),
548 we have solved a couple of bugs of the earlier code where s->cert
549 was used as if it could not have been shared with other SSL structures.
551 Note that using the SSL API in certain dirty ways now will result
552 in different behaviour than observed with earlier library versions:
553 Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
554 does not influence s as it used to.
556 In order to clean up things more thoroughly, inside SSL_SESSION
557 we don't use CERT any longer, but a new structure SESS_CERT
558 that holds per-session data (if available); currently, this is
559 the peer's certificate chain and, for clients, the server's certificate
560 and temporary key. CERT holds only those values that can have
561 meaningful defaults in an SSL_CTX.
564 *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure
565 from the internal representation. Various PKCS#7 fixes: remove some
566 evil casts and set the enc_dig_alg field properly based on the signing
570 *) Allow PKCS#12 password to be set from the command line or the
571 environment. Let 'ca' get its config file name from the environment
572 variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req'
576 *) Allow certificate policies extension to use an IA5STRING for the
577 organization field. This is contrary to the PKIX definition but
578 VeriSign uses it and IE5 only recognises this form. Document 'x509'
582 *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic,
583 without disallowing inline assembler and the like for non-pedantic builds.
586 *) Support Borland C++ builder.
587 [Janez Jere <jj@void.si>, modified by Ulf Möller]
592 *) SHA-1 cleanups and performance enhancements.
593 [Andy Polyakov <appro@fy.chalmers.se>]
595 *) Sparc v8plus assembler for the bignum library.
596 [Andy Polyakov <appro@fy.chalmers.se>]
598 *) Accept any -xxx and +xxx compiler options in Configure.
601 *) Update HPUX configuration.
604 *) Add missing sk_<type>_unshift() function to safestack.h
605 [Ralf S. Engelschall]
607 *) New function SSL_CTX_use_certificate_chain_file that sets the
608 "extra_cert"s in addition to the certificate. (This makes sense
609 only for "PEM" format files, as chains as a whole are not
613 *) Support verify_depth from the SSL API.
614 x509_vfy.c had what can be considered an off-by-one-error:
615 Its depth (which was not part of the external interface)
616 was actually counting the number of certificates in a chain;
617 now it really counts the depth.
620 *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used
621 instead of X509err, which often resulted in confusing error
622 messages since the error codes are not globally unique
623 (e.g. an alleged error in ssl3_accept when a certificate
624 didn't match the private key).
626 *) New function SSL_CTX_set_session_id_context that allows to set a default
627 value (so that you don't need SSL_set_session_id_context for each
628 connection using the SSL_CTX).
631 *) OAEP decoding bug fix.
634 *) Support INSTALL_PREFIX for package builders, as proposed by
638 *) New Configure options "threads" and "no-threads". For systems
639 where the proper compiler options are known (currently Solaris
640 and Linux), "threads" is the default.
643 *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
646 *) Install various scripts to $(OPENSSLDIR)/misc, not to
647 $(INSTALLTOP)/bin -- they shouldn't clutter directories
648 such as /usr/local/bin.
651 *) "make linux-shared" to build shared libraries.
652 [Niels Poppe <niels@netbox.org>]
654 *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
657 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
658 extension adding in x509 utility.
661 *) Remove NOPROTO sections and error code comments.
664 *) Partial rewrite of the DEF file generator to now parse the ANSI
668 *) New Configure options --prefix=DIR and --openssldir=DIR.
671 *) Complete rewrite of the error code script(s). It is all now handled
672 by one script at the top level which handles error code gathering,
673 header rewriting and C source file generation. It should be much better
674 than the old method: it now uses a modified version of Ulf's parser to
675 read the ANSI prototypes in all header files (thus the old K&R definitions
676 aren't needed for error creation any more) and do a better job of
677 translating function codes into names. The old 'ASN1 error code imbedded
678 in a comment' is no longer necessary and it doesn't use .err files which
679 have now been deleted. Also the error code call doesn't have to appear all
680 on one line (which resulted in some large lines...).
683 *) Change #include filenames from <foo.h> to <openssl/foo.h>.
686 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
687 0 (which usually indicates a closed connection), but continue reading.
690 *) Fix some race conditions.
693 *) Add support for CRL distribution points extension. Add Certificate
694 Policies and CRL distribution points documentation.
697 *) Move the autogenerated header file parts to crypto/opensslconf.h.
700 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
701 8 of keying material. Merlin has also confirmed interop with this fix
702 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
703 [Merlin Hughes <merlin@baltimore.ie>]
705 *) Fix lots of warnings.
706 [Richard Levitte <levitte@stacken.kth.se>]
708 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
709 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
710 [Richard Levitte <levitte@stacken.kth.se>]
712 *) Fix problems with sizeof(long) == 8.
713 [Andy Polyakov <appro@fy.chalmers.se>]
715 *) Change functions to ANSI C.
718 *) Fix typos in error codes.
719 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
721 *) Remove defunct assembler files from Configure.
724 *) SPARC v8 assembler BIGNUM implementation.
725 [Andy Polyakov <appro@fy.chalmers.se>]
727 *) Support for Certificate Policies extension: both print and set.
728 Various additions to support the r2i method this uses.
731 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
732 return a const string when you are expecting an allocated buffer.
735 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
736 types DirectoryString and DisplayText.
739 *) Add code to allow r2i extensions to access the configuration database,
740 add an LHASH database driver and add several ctx helper functions.
743 *) Fix an evil bug in bn_expand2() which caused various BN functions to
744 fail when they extended the size of a BIGNUM.
747 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
748 support typesafe stack.
751 *) Fix typo in SSL_[gs]et_options().
752 [Nils Frostberg <nils@medcom.se>]
754 *) Delete various functions and files that belonged to the (now obsolete)
755 old X509V3 handling code.
758 *) New Configure option "rsaref".
761 *) Don't auto-generate pem.h.
764 *) Introduce type-safe ASN.1 SETs.
767 *) Convert various additional casted stacks to type-safe STACK_OF() variants.
768 [Ben Laurie, Ralf S. Engelschall, Steve Henson]
770 *) Introduce type-safe STACKs. This will almost certainly break lots of code
771 that links with OpenSSL (well at least cause lots of warnings), but fear
772 not: the conversion is trivial, and it eliminates loads of evil casts. A
773 few STACKed things have been converted already. Feel free to convert more.
774 In the fullness of time, I'll do away with the STACK type altogether.
777 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
778 specified in <certfile> by updating the entry in the index.txt file.
779 This way one no longer has to edit the index.txt file manually for
780 revoking a certificate. The -revoke option does the gory details now.
781 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
783 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
784 `-text' option at all and this way the `-noout -text' combination was
785 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
786 [Ralf S. Engelschall]
788 *) Make sure a corresponding plain text error message exists for the
789 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
790 verify callback function determined that a certificate was revoked.
791 [Ralf S. Engelschall]
793 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
794 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
795 all available cipers including rc5, which was forgotten until now.
796 In order to let the testing shell script know which algorithms
797 are available, a new (up to now undocumented) command
798 "openssl list-cipher-commands" is used.
801 *) Bugfix: s_client occasionally would sleep in select() when
802 it should have checked SSL_pending() first.
805 *) New functions DSA_do_sign and DSA_do_verify to provide access to
806 the raw DSA values prior to ASN.1 encoding.
809 *) Tweaks to Configure
810 [Niels Poppe <niels@netbox.org>]
812 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
816 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
819 *) New config option to avoid instructions that are illegal on the 80386.
820 The default code is faster, but requires at least a 486.
823 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
824 SSL2_SERVER_VERSION (not used at all) macros, which are now the
825 same as SSL2_VERSION anyway.
828 *) New "-showcerts" option for s_client.
831 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
832 application. Various cleanups and fixes.
835 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
836 modify error routines to work internally. Add error codes and PBE init
837 to library startup routines.
840 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
841 packing functions to asn1 and evp. Changed function names and error
845 *) PKCS12 integration: and so it begins... First of several patches to
846 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
850 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
851 and display support for Thawte strong extranet extension.
854 *) Add LinuxPPC support.
855 [Jeff Dubrule <igor@pobox.org>]
857 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
858 bn_div_words in alpha.s.
859 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
861 *) Make sure the RSA OAEP test is skipped under -DRSAref because
862 OAEP isn't supported when OpenSSL is built with RSAref.
863 [Ulf Moeller <ulf@fitug.de>]
865 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
866 so they no longer are missing under -DNOPROTO.
867 [Soren S. Jorvang <soren@t.dk>]
870 Changes between 0.9.1c and 0.9.2b [22 Mar 1999]
872 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
873 doesn't work when the session is reused. Coming soon!
876 *) Fix a security hole, that allows sessions to be reused in the wrong
877 context thus bypassing client cert protection! All software that uses
878 client certs and session caches in multiple contexts NEEDS PATCHING to
879 allow session reuse! A fuller solution is in the works.
880 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
882 *) Some more source tree cleanups (removed obsolete files
883 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
884 permission on "config" script to be executable) and a fix for the INSTALL
886 [Ulf Moeller <ulf@fitug.de>]
888 *) Remove some legacy and erroneous uses of malloc, free instead of
890 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
892 *) Make rsa_oaep_test return non-zero on error.
893 [Ulf Moeller <ulf@fitug.de>]
895 *) Add support for native Solaris shared libraries. Configure
896 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
897 if someone would make that last step automatic.
898 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
900 *) ctx_size was not built with the right compiler during "make links". Fixed.
903 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
904 except NULL ciphers". This means the default cipher list will no longer
905 enable NULL ciphers. They need to be specifically enabled e.g. with
906 the string "DEFAULT:eNULL".
909 *) Fix to RSA private encryption routines: if p < q then it would
910 occasionally produce an invalid result. This will only happen with
911 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
914 *) Be less restrictive and allow also `perl util/perlpath.pl
915 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
916 because this way one can also use an interpreter named `perl5' (which is
917 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
918 installed as `perl').
919 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
921 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
922 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
924 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
925 advapi32.lib to Win32 build and change the pem test comparision
926 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
927 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
928 and crypto/des/ede_cbcm_enc.c.
931 *) DES quad checksum was broken on big-endian architectures. Fixed.
934 *) Comment out two functions in bio.h that aren't implemented. Fix up the
935 Win32 test batch file so it (might) work again. The Win32 test batch file
936 is horrible: I feel ill....
939 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
940 in e_os.h. Audit of header files to check ANSI and non ANSI
941 sections: 10 functions were absent from non ANSI section and not exported
942 from Windows DLLs. Fixed up libeay.num for new functions.
945 *) Make `openssl version' output lines consistent.
946 [Ralf S. Engelschall]
948 *) Fix Win32 symbol export lists for BIO functions: Added
949 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
950 to ms/libeay{16,32}.def.
951 [Ralf S. Engelschall]
953 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
954 fine under Unix and passes some trivial tests I've now added. But the
955 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
956 added to make sure no one expects that this stuff really works in the
957 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
958 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
960 [Ralf S. Engelschall]
962 *) Fix the generation of two part addresses in perl.
963 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
965 *) Add config entry for Linux on MIPS.
966 [John Tobey <jtobey@channel1.com>]
968 *) Make links whenever Configure is run, unless we are on Windoze.
971 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
972 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
976 *) Add a useful kludge to allow package maintainers to specify compiler and
977 other platforms details on the command line without having to patch the
978 Configure script everytime: One now can use ``perl Configure
979 <id>:<details>'', i.e. platform ids are allowed to have details appended
980 to them (seperated by colons). This is treated as there would be a static
981 pre-configured entry in Configure's %table under key <id> with value
982 <details> and ``perl Configure <id>'' is called. So, when you want to
983 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
984 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
985 now, which overrides the FreeBSD-elf entry on-the-fly.
986 [Ralf S. Engelschall]
988 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
991 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
992 on the `perl Configure ...' command line. This way one can compile
993 OpenSSL libraries with Position Independent Code (PIC) which is needed
994 for linking it into DSOs.
995 [Ralf S. Engelschall]
997 *) Remarkably, export ciphers were totally broken and no-one had noticed!
1001 *) Cleaned up the LICENSE document: The official contact for any license
1002 questions now is the OpenSSL core team under openssl-core@openssl.org.
1003 And add a paragraph about the dual-license situation to make sure people
1004 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
1005 to the OpenSSL toolkit.
1006 [Ralf S. Engelschall]
1008 *) General source tree makefile cleanups: Made `making xxx in yyy...'
1009 display consistent in the source tree and replaced `/bin/rm' by `rm'.
1010 Additonally cleaned up the `make links' target: Remove unnecessary
1011 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
1012 to speed processing and no longer clutter the display with confusing
1013 stuff. Instead only the actually done links are displayed.
1014 [Ralf S. Engelschall]
1016 *) Permit null encryption ciphersuites, used for authentication only. It used
1017 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
1018 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
1022 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
1023 signed attributes when verifying signatures (this would break them),
1024 the detached data encoding was wrong and public keys obtained using
1025 X509_get_pubkey() weren't freed.
1028 *) Add text documentation for the BUFFER functions. Also added a work around
1029 to a Win95 console bug. This was triggered by the password read stuff: the
1030 last character typed gets carried over to the next fread(). If you were
1031 generating a new cert request using 'req' for example then the last
1032 character of the passphrase would be CR which would then enter the first
1036 *) Added the new `Includes OpenSSL Cryptography Software' button as
1037 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
1038 button and can be used by applications based on OpenSSL to show the
1039 relationship to the OpenSSL project.
1040 [Ralf S. Engelschall]
1042 *) Remove confusing variables in function signatures in files
1043 ssl/ssl_lib.c and ssl/ssl.h.
1044 [Lennart Bong <lob@kulthea.stacken.kth.se>]
1046 *) Don't install bss_file.c under PREFIX/include/
1047 [Lennart Bong <lob@kulthea.stacken.kth.se>]
1049 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
1050 functions that return function pointers and has support for NT specific
1051 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
1052 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
1053 unsigned to signed types: this was killing the Win32 compile.
1056 *) Add new certificate file to stack functions,
1057 SSL_add_dir_cert_subjects_to_stack() and
1058 SSL_add_file_cert_subjects_to_stack(). These largely supplant
1059 SSL_load_client_CA_file(), and can be used to add multiple certs easily
1060 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
1061 This means that Apache-SSL and similar packages don't have to mess around
1062 to add as many CAs as they want to the preferred list.
1065 *) Experiment with doxygen documentation. Currently only partially applied to
1067 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
1068 openssl.doxy as the configuration file.
1071 *) Get rid of remaining C++-style comments which strict C compilers hate.
1072 [Ralf S. Engelschall, pointed out by Carlos Amengual]
1074 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
1075 compiled in by default: it has problems with large keys.
1078 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
1079 DH private keys and/or callback functions which directly correspond to
1080 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
1081 is needed for applications which have to configure certificates on a
1082 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
1084 For the RSA certificate situation is makes no difference, but
1085 for the DSA certificate situation this fixes the "no shared cipher"
1086 problem where the OpenSSL cipher selection procedure failed because the
1087 temporary keys were not overtaken from the context and the API provided
1088 no way to reconfigure them.
1089 The new functions now let applications reconfigure the stuff and they
1090 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
1091 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
1092 non-public-API function ssl_cert_instantiate() is used as a helper
1093 function and also to reduce code redundancy inside ssl_rsa.c.
1094 [Ralf S. Engelschall]
1096 *) Move s_server -dcert and -dkey options out of the undocumented feature
1097 area because they are useful for the DSA situation and should be
1098 recognized by the users.
1099 [Ralf S. Engelschall]
1101 *) Fix the cipher decision scheme for export ciphers: the export bits are
1102 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
1103 SSL_EXP_MASK. So, the original variable has to be used instead of the
1104 already masked variable.
1105 [Richard Levitte <levitte@stacken.kth.se>]
1107 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
1108 [Richard Levitte <levitte@stacken.kth.se>]
1110 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
1111 from `int' to `unsigned int' because it's a length and initialized by
1112 EVP_DigestFinal() which expects an `unsigned int *'.
1113 [Richard Levitte <levitte@stacken.kth.se>]
1115 *) Don't hard-code path to Perl interpreter on shebang line of Configure
1116 script. Instead use the usual Shell->Perl transition trick.
1117 [Ralf S. Engelschall]
1119 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
1120 (in addition to RSA certificates) to match the behaviour of `openssl dsa
1121 -noout -modulus' as it's already the case for `openssl rsa -noout
1122 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
1123 currently the public key is printed (a decision which was already done by
1124 `openssl dsa -modulus' in the past) which serves a similar purpose.
1125 Additionally the NO_RSA no longer completely removes the whole -modulus
1126 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
1128 [Ralf S. Engelschall]
1130 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
1131 BIO. See the source (crypto/evp/bio_ok.c) for more info.
1132 [Arne Ansper <arne@ats.cyber.ee>]
1134 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
1135 to be added. Now both 'req' and 'ca' can use new objects defined in the
1139 *) Add cool BIO that does syslog (or event log on NT).
1140 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
1142 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
1143 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
1144 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
1145 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
1148 *) Add preliminary config info for new extension code.
1151 *) Make RSA_NO_PADDING really use no padding.
1152 [Ulf Moeller <ulf@fitug.de>]
1154 *) Generate errors when private/public key check is done.
1157 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
1158 for some CRL extensions and new objects added.
1161 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
1162 key usage extension and fuller support for authority key id.
1165 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
1166 padding method for RSA, which is recommended for new applications in PKCS
1167 #1 v2.0 (RFC 2437, October 1998).
1168 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
1169 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
1170 against Bleichbacher's attack on RSA.
1171 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
1174 *) Updates to the new SSL compression code
1175 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
1177 *) Fix so that the version number in the master secret, when passed
1178 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
1179 (because the server will not accept higher), that the version number
1180 is 0x03,0x01, not 0x03,0x00
1181 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
1183 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
1184 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
1185 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
1188 *) Support for RAW extensions where an arbitrary extension can be
1189 created by including its DER encoding. See apps/openssl.cnf for
1193 *) Make sure latest Perl versions don't interpret some generated C array
1194 code as Perl array code in the crypto/err/err_genc.pl script.
1195 [Lars Weber <3weber@informatik.uni-hamburg.de>]
1197 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
1198 not many people have the assembler. Various Win32 compilation fixes and
1199 update to the INSTALL.W32 file with (hopefully) more accurate Win32
1203 *) Modify configure script 'Configure' to automatically create crypto/date.h
1204 file under Win32 and also build pem.h from pem.org. New script
1205 util/mkfiles.pl to create the MINFO file on environments that can't do a
1206 'make files': perl util/mkfiles.pl >MINFO should work.
1209 *) Major rework of DES function declarations, in the pursuit of correctness
1210 and purity. As a result, many evil casts evaporated, and some weirdness,
1211 too. You may find this causes warnings in your code. Zapping your evil
1212 casts will probably fix them. Mostly.
1215 *) Fix for a typo in asn1.h. Bug fix to object creation script
1216 obj_dat.pl. It considered a zero in an object definition to mean
1217 "end of object": none of the objects in objects.h have any zeros
1218 so it wasn't spotted.
1219 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
1221 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
1222 Masking (CBCM). In the absence of test vectors, the best I have been able
1223 to do is check that the decrypt undoes the encrypt, so far. Send me test
1224 vectors if you have them.
1227 *) Correct calculation of key length for export ciphers (too much space was
1228 allocated for null ciphers). This has not been tested!
1231 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
1232 message is now correct (it understands "crypto" and "ssl" on its
1233 command line). There is also now an "update" option. This will update
1234 the util/ssleay.num and util/libeay.num files with any new functions.
1236 perl util/mkdef.pl crypto ssl update
1237 it will update them.
1240 *) Overhauled the Perl interface (perl/*):
1241 - ported BN stuff to OpenSSL's different BN library
1242 - made the perl/ source tree CVS-aware
1243 - renamed the package from SSLeay to OpenSSL (the files still contain
1244 their history because I've copied them in the repository)
1245 - removed obsolete files (the test scripts will be replaced
1246 by better Test::Harness variants in the future)
1247 [Ralf S. Engelschall]
1249 *) First cut for a very conservative source tree cleanup:
1250 1. merge various obsolete readme texts into doc/ssleay.txt
1251 where we collect the old documents and readme texts.
1252 2. remove the first part of files where I'm already sure that we no
1253 longer need them because of three reasons: either they are just temporary
1254 files which were left by Eric or they are preserved original files where
1255 I've verified that the diff is also available in the CVS via "cvs diff
1256 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
1257 the crypto/md/ stuff).
1258 [Ralf S. Engelschall]
1260 *) More extension code. Incomplete support for subject and issuer alt
1261 name, issuer and authority key id. Change the i2v function parameters
1262 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
1263 what that's for :-) Fix to ASN1 macro which messed up
1264 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
1267 *) Preliminary support for ENUMERATED type. This is largely copied from the
1271 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
1272 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
1274 *) Make sure `make rehash' target really finds the `openssl' program.
1275 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
1277 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
1278 like to hear about it if this slows down other processors.
1281 *) Add CygWin32 platform information to Configure script.
1282 [Alan Batie <batie@aahz.jf.intel.com>]
1284 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
1285 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
1287 *) New program nseq to manipulate netscape certificate sequences
1290 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
1294 *) Fixes to BN code. Previously the default was to define BN_RECURSION
1295 but the BN code had some problems that would cause failures when
1296 doing certificate verification and some other functions.
1297 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
1299 *) Add ASN1 and PEM code to support netscape certificate sequences.
1302 *) Add ASN1 and PEM code to support netscape certificate sequences.
1305 *) Add several PKIX and private extended key usage OIDs.
1308 *) Modify the 'ca' program to handle the new extension code. Modify
1309 openssl.cnf for new extension format, add comments.
1312 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
1313 and add a sample to openssl.cnf so req -x509 now adds appropriate
1317 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
1318 error code, add initial support to X509_print() and x509 application.
1321 *) Takes a deep breath and start addding X509 V3 extension support code. Add
1322 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
1323 stuff is currently isolated and isn't even compiled yet.
1326 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
1327 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
1328 Removed the versions check from X509 routines when loading extensions:
1329 this allows certain broken certificates that don't set the version
1330 properly to be processed.
1333 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
1334 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
1335 can still be regenerated with "make depend".
1338 *) Spelling mistake in C version of CAST-128.
1339 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
1341 *) Changes to the error generation code. The perl script err-code.pl
1342 now reads in the old error codes and retains the old numbers, only
1343 adding new ones if necessary. It also only changes the .err files if new
1344 codes are added. The makefiles have been modified to only insert errors
1345 when needed (to avoid needlessly modifying header files). This is done
1346 by only inserting errors if the .err file is newer than the auto generated
1347 C file. To rebuild all the error codes from scratch (the old behaviour)
1348 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
1349 or delete all the .err files.
1352 *) CAST-128 was incorrectly implemented for short keys. The C version has
1353 been fixed, but is untested. The assembler versions are also fixed, but
1354 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
1355 to regenerate it if needed.
1356 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
1357 Hagino <itojun@kame.net>]
1359 *) File was opened incorrectly in randfile.c.
1360 [Ulf Möller <ulf@fitug.de>]
1362 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
1363 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
1364 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
1365 al: it's just almost always a UTCTime. Note this patch adds new error
1366 codes so do a "make errors" if there are problems.
1369 *) Correct Linux 1 recognition in config.
1370 [Ulf Möller <ulf@fitug.de>]
1372 *) Remove pointless MD5 hash when using DSA keys in ca.
1373 [Anonymous <nobody@replay.com>]
1375 *) Generate an error if given an empty string as a cert directory. Also
1376 generate an error if handed NULL (previously returned 0 to indicate an
1377 error, but didn't set one).
1378 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
1380 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
1383 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
1384 parameters. This was causing a warning which killed off the Win32 compile.
1387 *) Remove C++ style comments from crypto/bn/bn_local.h.
1388 [Neil Costigan <neil.costigan@celocom.com>]
1390 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
1391 based on a text string, looking up short and long names and finally
1392 "dot" format. The "dot" format stuff didn't work. Added new function
1393 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
1394 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
1395 OID is not part of the table.
1398 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
1399 X509_LOOKUP_by_alias().
1402 *) Sort openssl functions by name.
1405 *) Get the gendsa program working (hopefully) and add it to app list. Remove
1406 encryption from sample DSA keys (in case anyone is interested the password
1410 *) Make _all_ *_free functions accept a NULL pointer.
1411 [Frans Heymans <fheymans@isaserver.be>]
1413 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
1415 [Anonymous <nobody@replay.com>]
1417 *) s_server should send the CAfile as acceptable CAs, not its own cert.
1418 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
1420 *) Don't blow it for numeric -newkey arguments to apps/req.
1421 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
1423 *) Temp key "for export" tests were wrong in s3_srvr.c.
1424 [Anonymous <nobody@replay.com>]
1426 *) Add prototype for temp key callback functions
1427 SSL_CTX_set_tmp_{rsa,dh}_callback().
1430 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
1431 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
1434 *) X509_name_add_entry() freed the wrong thing after an error.
1435 [Arne Ansper <arne@ats.cyber.ee>]
1437 *) rsa_eay.c would attempt to free a NULL context.
1438 [Arne Ansper <arne@ats.cyber.ee>]
1440 *) BIO_s_socket() had a broken should_retry() on Windoze.
1441 [Arne Ansper <arne@ats.cyber.ee>]
1443 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
1444 [Arne Ansper <arne@ats.cyber.ee>]
1446 *) Make sure the already existing X509_STORE->depth variable is initialized
1447 in X509_STORE_new(), but document the fact that this variable is still
1448 unused in the certificate verification process.
1449 [Ralf S. Engelschall]
1451 *) Fix the various library and apps files to free up pkeys obtained from
1452 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
1455 *) Fix reference counting in X509_PUBKEY_get(). This makes
1456 demos/maurice/example2.c work, amongst others, probably.
1457 [Steve Henson and Ben Laurie]
1459 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
1460 `openssl' and second, the shortcut symlinks for the `openssl <command>'
1461 are no longer created. This way we have a single and consistent command
1462 line interface `openssl <command>', similar to `cvs <command>'.
1463 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
1465 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
1466 BIT STRING wrapper always have zero unused bits.
1469 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
1472 *) Make the top-level INSTALL documentation easier to understand.
1475 *) Makefiles updated to exit if an error occurs in a sub-directory
1476 make (including if user presses ^C) [Paul Sutton]
1478 *) Make Montgomery context stuff explicit in RSA data structure.
1481 *) Fix build order of pem and err to allow for generated pem.h.
1484 *) Fix renumbering bug in X509_NAME_delete_entry().
1487 *) Enhanced the err-ins.pl script so it makes the error library number
1488 global and can add a library name. This is needed for external ASN1 and
1489 other error libraries.
1492 *) Fixed sk_insert which never worked properly.
1495 *) Fix ASN1 macros so they can handle indefinite length construted
1496 EXPLICIT tags. Some non standard certificates use these: they can now
1500 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
1501 into a single doc/ssleay.txt bundle. This way the information is still
1502 preserved but no longer messes up this directory. Now it's new room for
1503 the new set of documenation files.
1504 [Ralf S. Engelschall]
1506 *) SETs were incorrectly DER encoded. This was a major pain, because they
1507 shared code with SEQUENCEs, which aren't coded the same. This means that
1508 almost everything to do with SETs or SEQUENCEs has either changed name or
1509 number of arguments.
1510 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
1512 *) Fix test data to work with the above.
1515 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
1516 was already fixed by Eric for 0.9.1 it seems.
1517 [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
1519 *) Autodetect FreeBSD3.
1522 *) Fix various bugs in Configure. This affects the following platforms:
1526 unixware-2.0-pentium
1530 *) Eliminate generated files from CVS. Reorder tests to regenerate files
1531 before they are needed.
1534 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
1538 Changes between 0.9.1b and 0.9.1c [23-Dec-1998]
1540 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
1541 changed SSLeay to OpenSSL in version strings.
1542 [Ralf S. Engelschall]
1544 *) Some fixups to the top-level documents.
1547 *) Fixed the nasty bug where rsaref.h was not found under compile-time
1548 because the symlink to include/ was missing.
1549 [Ralf S. Engelschall]
1551 *) Incorporated the popular no-RSA/DSA-only patches
1552 which allow to compile a RSA-free SSLeay.
1553 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
1555 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
1556 when "ssleay" is still not found.
1557 [Ralf S. Engelschall]
1559 *) Added more platforms to Configure: Cray T3E, HPUX 11,
1560 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
1562 *) Updated the README file.
1563 [Ralf S. Engelschall]
1565 *) Added various .cvsignore files in the CVS repository subdirs
1566 to make a "cvs update" really silent.
1567 [Ralf S. Engelschall]
1569 *) Recompiled the error-definition header files and added
1570 missing symbols to the Win32 linker tables.
1571 [Ralf S. Engelschall]
1573 *) Cleaned up the top-level documents;
1574 o new files: CHANGES and LICENSE
1575 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
1576 o merged COPYRIGHT into LICENSE
1577 o removed obsolete TODO file
1578 o renamed MICROSOFT to INSTALL.W32
1579 [Ralf S. Engelschall]
1581 *) Removed dummy files from the 0.9.1b source tree:
1582 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
1583 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f

1586 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
1587 [Ralf S. Engelschall]
1589 *) Added various platform portability fixes.
1592 *) The Genesis of the OpenSSL rpject:
1593 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
1594 Young and Tim J. Hudson created while they were working for C2Net until
1596 [The OpenSSL Project]
1599 Changes between 0.9.0b and 0.9.1b [not released]
1601 *) Updated a few CA certificates under certs/
1604 *) Changed some BIGNUM api stuff.
1607 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
1608 DGUX x86, Linux Alpha, etc.
1611 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
1612 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
1616 *) Add -strparse option to asn1pars program which parses nested
1618 [Dr Stephen Henson <shenson@bigfoot.com>]
1620 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
1623 *) DSA fix for "ca" program.
1626 *) Added "-genkey" option to "dsaparam" program.
1629 *) Added RIPE MD160 (rmd160) message digest.
1632 *) Added -a (all) option to "ssleay version" command.
1635 *) Added PLATFORM define which is the id given to Configure.
1638 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
1641 *) Extended the ASN.1 parser routines.
1644 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
1647 *) Added a BN_CTX to the BN library.
1650 *) Fixed the weak key values in DES library
1653 *) Changed API in EVP library for cipher aliases.
1656 *) Added support for RC2/64bit cipher.
1659 *) Converted the lhash library to the crypto/mem.c functions.
1662 *) Added more recognized ASN.1 object ids.
1665 *) Added more RSA padding checks for SSL/TLS.
1668 *) Added BIO proxy/filter functionality.
1671 *) Added extra_certs to SSL_CTX which can be used
1672 send extra CA certificates to the client in the CA cert chain sending
1673 process. It can be configured with SSL_CTX_add_extra_chain_cert().
1676 *) Now Fortezza is denied in the authentication phase because
1677 this is key exchange mechanism is not supported by SSLeay at all.
1680 *) Additional PKCS1 checks.
1683 *) Support the string "TLSv1" for all TLS v1 ciphers.
1686 *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
1687 ex_data index of the SSL context in the X509_STORE_CTX ex_data.
1690 *) Fixed a few memory leaks.
1693 *) Fixed various code and comment typos.
1696 *) A minor bug in ssl/s3_clnt.c where there would always be 4 0
1697 bytes sent in the client random.
