5 Changes between 0.9.4 and 0.9.5 [xx XXX 1999]
7 *) Fixes and enhancements to the 'x509' utility. It allowed a message
8 digest to be passed on the command line but it only used this
9 parameter when signing a certificate. Modified so all relevant
10 operations are affected by the digest parameter including the
11 -fingerprint and -x509toreq options. Also -x509toreq choked if a
12 DSA key was used because it didn't fix the digest.
15 *) Very preliminary certificate chain verify code. Currently just tests
16 the untrusted certificates for consistency with the verify purpose
17 (which is set when the X509_STORE_CTX structure is set up) and checks
18 the pathlength. There is a NO_CHAIN_VERIFY compilation option to keep
19 the old behaviour: this is because when it is finally working it will
20 reject chains with invalid extensions whereas before it made no checks
23 Preliminary untested trust code.
25 Also added X509_STORE_CTX_new() and X509_STORE_CTX_free() functions
26 which should be used for version portability: especially since the
27 verify structure is likely to change more often now.
29 Two new options to the verify program: -untrusted allows a set of
30 untrusted certificates to be passed in and -purpose which sets the
31 intended purpose of the certificate. If a purpose is set then the
32 new chain verify code is used to check extension consistency.
35 *) Support for the authority information access extension.
38 *) Modify RSA and DSA PEM read routines to transparently handle
39 PKCS#8 format private keys. New *_PUBKEY_* functions that handle
40 public keys in a format compatible with certificate
41 SubjectPublicKeyInfo structures. Unfortunately there were already
42 functions called *_PublicKey_* which used various odd formats so
43 these are retained for compatability: however the DSA variants were
44 never in a public release so they have been deleted. Changed dsa/rsa
45 utilities to handle the new format: note no releases ever handled public
46 keys so we should be OK.
48 The primary motivation for this change is to avoid the same fiasco
49 that dogs private keys: there are several incompatible private key
50 formats some of which are standard and some OpenSSL specific and
51 require various evil hacks to allow partial transparent handling and
52 even then it doesn't work with DER formats. Given the option anything
53 other than PKCS#8 should be dumped: but the other formats have to
54 stay in the name of compatability.
56 With public keys and the benefit of hindsight one standard format
57 is used which works with EVP_PKEY, RSA or DSA structures: though
58 it clearly returns an error if you try to read the wrong kind of key.
60 Added a -pubkey option to the 'x509' utility to output the public key.
61 Also rename the EVP_PKEY_get_*() to EVP_PKEY_rget_*() and add
62 EVP_PKEY_rset_*() functions that do the same as the EVP_PKEY_assign_*()
63 except they up the reference count of the added key (they don't "swallow"
67 *) Fixes to crypto/x509/by_file.c the code to read in certificates and
68 CRLs would fail if the file contained no certificates or no CRLs:
69 added a new function to read in both types and return the number
70 read: this means that if none are read it will be an error. The
71 DER versions of the certificate and CRL reader would always fail
72 because it isn't possible to mix certificates and CRLs in DER format
73 without choking one or the other routine. Changed this to just read
74 a certificate: this is the best we can do. Also modified the code
75 in apps/verify.c to take notice of return codes: it was previously
76 attempting to read in certificates from NULL pointers and ignoring
77 any errors: this is one reason why the cert and CRL reader seemed
78 to work. It doesn't check return codes from the default certificate
79 routines: these may well fail if the certificates aren't installed.
82 *) Code to support otherName option in GeneralName.
85 *) First update to verify code. Change the verify utility
86 so it warns if it is passed a self signed certificate:
87 for consistency with the normal behaviour. X509_verify
88 has been modified to it will now verify a self signed
89 certificate if *exactly* the same certificate appears
90 in the store: it was previously impossible to trust a
91 single self signed certificate. This means that:
93 now gives a warning about a self signed certificate but
94 openssl verify -CAfile ss.pem ss.pem
98 *) For servers, store verify_result in SSL_SESSION data structure
99 (and add it to external session representation).
100 This is needed when client certificate verifications fails,
101 but an application-provided verification callback (set by
102 SSL_CTX_set_cert_verify_callback) allows accepting the session
103 anyway (i.e. leaves x509_store_ctx->error != X509_V_OK
104 but returns 1): When the session is reused, we have to set
105 ssl->verify_result to the appropriate error code to avoid
107 [Bodo Moeller, problem pointed out by Lutz Jaenicke]
109 *) Fix a bug in the new PKCS#7 code: it didn't consider the
110 case in PKCS7_dataInit() where the signed PKCS7 structure
111 didn't contain any existing data because it was being created.
112 [Po-Cheng Chen <pocheng@nst.com.tw>, slightly modified by Steve Henson]
114 *) Add a salt to the key derivation routines in enc.c. This
115 forms the first 8 bytes of the encrypted file. Also add a
116 -S option to allow a salt to be input on the command line.
119 *) New function X509_cmp(). Oddly enough there wasn't a function
120 to compare two certificates. We do this by working out the SHA1
121 hash and comparing that. X509_cmp() will be needed by the trust
125 *) Correctly increment the reference count in the SSL_SESSION pointer
126 returned from SSL_get_session().
127 [Geoff Thorpe <geoff@eu.c2.net>]
129 *) Fix for 'req': it was adding a null to request attributes.
130 Also change the X509_LOOKUP and X509_INFO code to handle
131 certificate auxiliary information.
134 *) Add support for 40 and 64 bit RC2 and RC4 algorithms: document
138 *) Add the possibility to add extra information to the memory leak
139 detecting output, to form tracebacks, showing from where each
140 allocation was originated. Also updated sid code to be multi-
144 *) Add options -text and -noout to pkcs7 utility and delete the
145 encryption options which never did anything. Update docs.
148 *) Add options to some of the utilities to allow the pass phrase
149 to be included on either the command line (not recommended on
150 OSes like Unix) or read from the environment. Update the
151 manpages and fix a few bugs.
154 *) Add a few manpages for some of the openssl commands.
157 *) Fix the -revoke option in ca. It was freeing up memory twice,
158 leaking and not finding already revoked certificates.
161 *) Extensive changes to support certificate auxiliary information.
162 This involves the use of X509_CERT_AUX structure and X509_AUX
163 functions. An X509_AUX function such as PEM_read_X509_AUX()
164 can still read in a certificate file in the usual way but it
165 will also read in any additional "auxiliary information". By
166 doing things this way a fair degree of compatability can be
167 retained: existing certificates can have this information added
168 using the new 'x509' options.
170 Current auxiliary information includes an "alias" and some trust
171 settings. The trust settings will ultimately be used in enhanced
172 certificate chain verification routines: currently a certificate
173 can only be trusted if it is self signed and then it is trusted
177 *) Fix assembler for Alpha (tested only on DEC OSF not Linux or *BSD). The
178 problem was that one of the replacement routines had not been working since
179 SSLeay releases. For now the offending routine has been replaced with
180 non-optimised assembler. Even so, this now gives around 95% performance
181 improvement for 1024 bit RSA signs.
184 *) Hack to fix PKCS#7 decryption when used with some unorthodox RC2
185 handling. Most clients have the effective key size in bits equal to
186 the key length in bits: so a 40 bit RC2 key uses a 40 bit (5 byte) key.
187 A few however don't do this and instead use the size of the decrypted key
188 to determine the RC2 key length and the AlgorithmIdentifier to determine
189 the effective key length. In this case the effective key lenth can still
190 be 40 bits but the key length can be 168 bits for example. This is fixed
191 by manually forcing an RC2 key into the EVP_PKEY structure because the
192 EVP code can't currently handle unusual RC2 key sizes: it always assumes
193 the key length and effective key length are equal.
196 *) Add a bunch of functions that should simplify the creation of
197 X509_NAME structures. Now you should be able to do:
198 X509_NAME_add_entry_by_txt(nm, "CN", MBSTRING_ASC, "Steve", -1, -1, 0);
199 and have it automatically work out the correct field type and fill in
200 the structures. The more adventurous can try:
201 X509_NAME_add_entry_by_txt(nm, field, MBSTRING_UTF8, str, -1, -1, 0);
202 and it will (hopefully) work out the correct multibyte encoding.
205 *) Change the 'req' utility to use the new field handling and multibyte
206 copy routines. Before the DN field creation was handled in an ad hoc
207 way in req, ca, and x509 which was rather broken and didn't support
208 BMPStrings or UTF8Strings. Since some software doesn't implement
209 BMPStrings or UTF8Strings yet, they can be enabled using the config file
210 using the dirstring_type option. See the new comment in the default
211 openssl.cnf for more info.
214 *) Make crypto/rand/md_rand.c more robust:
215 - Assure unique random numbers after fork().
216 - Make sure that concurrent threads access the global counter and
217 md serializably so that we never lose entropy in them
218 or use exactly the same state in multiple threads.
219 Access to the large state is not always serializable because
220 the additional locking could be a performance killer, and
221 md should be large enough anyway.
224 *) New file apps/app_rand.c with commonly needed functionality
225 for handling the random seed file.
227 Use the random seed file in some applications that previously did not:
229 dsaparam -genkey (which also ignored its `-rand' option),
233 Except on systems with /dev/urandom, it is crucial to have a random
234 seed file at least for key creation, DSA signing, and for DH exchanges;
235 for RSA signatures we could do without one.
237 gendh and gendsa (unlike genrsa) used to read only the first byte
238 of each file listed in the `-rand' option. The function as previously
239 found in genrsa is now in app_rand.c and is used by all programs
240 that support `-rand'.
243 *) In RAND_write_file, use mode 0600 for creating files;
244 don't just chmod when it may be too late.
247 *) Report an error from X509_STORE_load_locations
248 when X509_LOOKUP_load_file or X509_LOOKUP_add_dir failed.
251 *) New function ASN1_mbstring_copy() this copies a string in either
252 ASCII, Unicode, Universal (4 bytes per character) or UTF8 format
253 into an ASN1_STRING type. A mask of permissible types is passed
254 and it chooses the "minimal" type to use or an error if not type
258 *) Add function equivalents to the various macros in asn1.h. The old
259 macros are retained with an M_ prefix. Code inside the library can
260 use the M_ macros. External code (including the openssl utility)
261 should *NOT* in order to be "shared library friendly".
264 *) Add various functions that can check a certificate's extensions
265 to see if it usable for various purposes such as SSL client,
266 server or S/MIME and CAs of these types. This is currently
267 VERY EXPERIMENTAL but will ultimately be used for certificate chain
268 verification. Also added a -purpose flag to x509 utility to
269 print out all the purposes.
272 *) Add a CRYPTO_EX_DATA to X509 certificate structure and associated
276 *) New X509V3_{X509,CRL,REVOKED}_get_d2i() functions. These will search
277 for, obtain and decode and extension and obtain its critical flag.
278 This allows all the necessary extension code to be handled in a
279 single function call.
282 *) RC4 tune-up featuring 30-40% performance improvement on most RISC
283 platforms. See crypto/rc4/rc4_enc.c for further details.
286 *) New -noout option to asn1parse. This causes no output to be produced
287 its main use is when combined with -strparse and -out to extract data
288 from a file (which may not be in ASN.1 format).
291 *) Fix for pkcs12 program. It was hashing an invalid certificate pointer
292 when producing the local key id.
293 [Richard Levitte <levitte@stacken.kth.se>]
295 *) New option -dhparam in s_server. This allows a DH parameter file to be
296 stated explicitly. If it is not stated then it tries the first server
297 certificate file. The previous behaviour hard coded the filename
301 *) Add -pubin and -pubout options to the rsa and dsa commands. These allow
302 a public key to be input or output. For example:
303 openssl rsa -in key.pem -pubout -out pubkey.pem
304 Also added necessary DSA public key functions to handle this.
307 *) Fix so PKCS7_dataVerify() doesn't crash if no certificates are contained
308 in the message. This was handled by allowing
309 X509_find_by_issuer_and_serial() to tolerate a NULL passed to it.
310 [Steve Henson, reported by Sampo Kellomaki <sampo@mail.neuronio.pt>]
312 *) Fix for bug in d2i_ASN1_bytes(): other ASN1 functions add an extra null
313 to the end of the strings whereas this didn't. This would cause problems
314 if strings read with d2i_ASN1_bytes() were later modified.
315 [Steve Henson, reported by Arne Ansper <arne@ats.cyber.ee>]
317 *) Fix for base64 decode bug. When a base64 bio reads only one line of
318 data and it contains EOF it will end up returning an error. This is
319 caused by input 46 bytes long. The cause is due to the way base64
320 BIOs find the start of base64 encoded data. They do this by trying a
321 trial decode on each line until they find one that works. When they
322 do a flag is set and it starts again knowing it can pass all the
323 data directly through the decoder. Unfortunately it doesn't reset
324 the context it uses. This means that if EOF is reached an attempt
325 is made to pass two EOFs through the context and this causes the
326 resulting error. This can also cause other problems as well. As is
327 usual with these problems it takes *ages* to find and the fix is
328 trivial: move one line.
329 [Steve Henson, reported by ian@uns.ns.ac.yu (Ivan Nejgebauer) ]
331 *) Ugly workaround to get s_client and s_server working under Windows. The
332 old code wouldn't work because it needed to select() on sockets and the
333 tty (for keypresses and to see if data could be written). Win32 only
334 supports select() on sockets so we select() with a 1s timeout on the
335 sockets and then see if any characters are waiting to be read, if none
336 are present then we retry, we also assume we can always write data to
337 the tty. This isn't nice because the code then blocks until we've
338 received a complete line of data and it is effectively polling the
339 keyboard at 1s intervals: however it's quite a bit better than not
340 working at all :-) A dedicated Windows application might handle this
341 with an event loop for example.
344 *) Enhance RSA_METHOD structure. Now there are two extra methods, rsa_sign
345 and rsa_verify. When the RSA_FLAGS_SIGN_VER option is set these functions
346 will be called when RSA_sign() and RSA_verify() are used. This is useful
347 if rsa_pub_dec() and rsa_priv_enc() equivalents are not available.
348 For this to work properly RSA_public_decrypt() and RSA_private_encrypt()
349 should *not* be used: RSA_sign() and RSA_verify() must be used instead.
350 This necessitated the support of an extra signature type NID_md5_sha1
351 for SSL signatures and modifications to the SSL library to use it instead
352 of calling RSA_public_decrypt() and RSA_private_encrypt().
355 *) Add new -verify -CAfile and -CApath options to the crl program, these
356 will lookup a CRL issuers certificate and verify the signature in a
357 similar way to the verify program. Tidy up the crl program so it
358 no longer acesses structures directly. Make the ASN1 CRL parsing a bit
359 less strict. It will now permit CRL extensions even if it is not
360 a V2 CRL: this will allow it to tolerate some broken CRLs.
363 *) Initialize all non-automatic variables each time one of the openssl
364 sub-programs is started (this is necessary as they may be started
365 multiple times from the "OpenSSL>" prompt).
366 [Lennart Bang, Bodo Moeller]
368 *) Preliminary compilation option RSA_NULL which disables RSA crypto without
369 removing all other RSA functionality (this is what NO_RSA does). This
370 is so (for example) those in the US can disable those operations covered
371 by the RSA patent while allowing storage and parsing of RSA keys and RSA
375 *) Non-copying interface to BIO pairs.
376 (still largely untested)
379 *) New function ANS1_tag2str() to convert an ASN1 tag to a descriptive
380 ASCII string. This was handled independently in various places before.
383 *) New functions UTF8_getc() and UTF8_putc() that parse and generate
384 UTF8 strings a character at a time.
387 *) Use client_version from client hello to select the protocol
388 (s23_srvr.c) and for RSA client key exchange verification
389 (s3_srvr.c), as required by the SSL 3.0/TLS 1.0 specifications.
392 *) Add various utility functions to handle SPKACs, these were previously
393 handled by poking round in the structure internals. Added new function
394 NETSCAPE_SPKI_print() to print out SPKAC and a new utility 'spkac' to
395 print, verify and generate SPKACs. Based on an original idea from
396 Massimiliano Pala <madwolf@comune.modena.it> but extensively modified.
399 *) RIPEMD160 is operational on all platforms and is back in 'make test'.
402 *) Allow the config file extension section to be overwritten on the
403 command line. Based on an original idea from Massimiliano Pala
404 <madwolf@comune.modena.it>. The new option is called -extensions
405 and can be applied to ca, req and x509. Also -reqexts to override
406 the request extensions in req and -crlexts to override the crl extensions
410 *) Add new feature to the SPKAC handling in ca. Now you can include
411 the same field multiple times by preceding it by "XXXX." for example:
414 this is the same syntax as used in the req config file.
417 *) Allow certificate extensions to be added to certificate requests. These
418 are specified in a 'req_extensions' option of the req section of the
419 config file. They can be printed out with the -text option to req but
420 are otherwise ignored at present.
423 *) Fix a horrible bug in enc_read() in crypto/evp/bio_enc.c: if the first
424 data read consists of only the final block it would not decrypted because
425 EVP_CipherUpdate() would correctly report zero bytes had been decrypted.
426 A misplaced 'break' also meant the decrypted final block might not be
427 copied until the next read.
430 *) Initial support for DH_METHOD. Again based on RSA_METHOD. Also added
431 a few extra parameters to the DH structure: these will be useful if
432 for example we want the value of 'q' or implement X9.42 DH.
435 *) Initial support for DSA_METHOD. This is based on the RSA_METHOD and
436 provides hooks that allow the default DSA functions or functions on a
437 "per key" basis to be replaced. This allows hardware acceleration and
438 hardware key storage to be handled without major modification to the
439 library. Also added low level modexp hooks and CRYPTO_EX structure and
440 associated functions.
443 *) Add a new flag to memory BIOs, BIO_FLAG_MEM_RDONLY. This marks the BIO
444 as "read only": it can't be written to and the buffer it points to will
445 not be freed. Reading from a read only BIO is much more efficient than
446 a normal memory BIO. This was added because there are several times when
447 an area of memory needs to be read from a BIO. The previous method was
448 to create a memory BIO and write the data to it, this results in two
449 copies of the data and an O(n^2) reading algorithm. There is a new
450 function BIO_new_mem_buf() which creates a read only memory BIO from
451 an area of memory. Also modified the PKCS#7 routines to use read only
455 *) Bugfix: ssl23_get_client_hello did not work properly when called in
456 state SSL23_ST_SR_CLNT_HELLO_B, i.e. when the first 7 bytes of
457 a SSLv2-compatible client hello for SSLv3 or TLSv1 could be read,
458 but a retry condition occured while trying to read the rest.
461 *) The PKCS7_ENC_CONTENT_new() function was setting the content type as
462 NID_pkcs7_encrypted by default: this was wrong since this should almost
463 always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle
464 the encrypted data type: this is a more sensible place to put it and it
465 allows the PKCS#12 code to be tidied up that duplicated this
469 *) Changed obj_dat.pl script so it takes its input and output files on
470 the command line. This should avoid shell escape redirection problems
474 *) Initial support for certificate extension requests, these are included
475 in things like Xenroll certificate requests. Included functions to allow
476 extensions to be obtained and added.
479 *) -crlf option to s_client and s_server for sending newlines as
480 CRLF (as required by many protocols).
483 Changes between 0.9.3a and 0.9.4 [09 Aug 1999]
485 *) Install libRSAglue.a when OpenSSL is built with RSAref.
486 [Ralf S. Engelschall]
488 *) A few more ``#ifndef NO_FP_API / #endif'' pairs for consistency.
489 [Andrija Antonijevic <TheAntony2@bigfoot.com>]
491 *) Fix -startdate and -enddate (which was missing) arguments to 'ca'
495 *) New function DSA_dup_DH, which duplicates DSA parameters/keys as
496 DH parameters/keys (q is lost during that conversion, but the resulting
497 DH parameters contain its length).
499 For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is
500 much faster than DH_generate_parameters (which creates parameters
501 where p = 2*q + 1), and also the smaller q makes DH computations
502 much more efficient (160-bit exponentiation instead of 1024-bit
503 exponentiation); so this provides a convenient way to support DHE
504 ciphersuites in SSL/TLS servers (see ssl/ssltest.c). It is of
505 utter importance to use
506 SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
508 SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
509 when such DH parameters are used, because otherwise small subgroup
510 attacks may become possible!
513 *) Avoid memory leak in i2d_DHparams.
516 *) Allow the -k option to be used more than once in the enc program:
517 this allows the same encrypted message to be read by multiple recipients.
520 *) New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts
521 an ASN1_OBJECT to a text string. If the "no_name" parameter is set then
522 it will always use the numerical form of the OID, even if it has a short
526 *) Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp
527 method only got called if p,q,dmp1,dmq1,iqmp components were present,
528 otherwise bn_mod_exp was called. In the case of hardware keys for example
529 no private key components need be present and it might store extra data
530 in the RSA structure, which cannot be accessed from bn_mod_exp.
531 By setting RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for
532 private key operations.
535 *) Added support for SPARC Linux.
538 *) pem_password_cb function type incompatibly changed from
539 typedef int pem_password_cb(char *buf, int size, int rwflag);
541 ....(char *buf, int size, int rwflag, void *userdata);
542 so that applications can pass data to their callbacks:
543 The PEM[_ASN1]_{read,write}... functions and macros now take an
544 additional void * argument, which is just handed through whenever
545 the password callback is called.
546 [Damien Miller <dmiller@ilogic.com.au>; tiny changes by Bodo Moeller]
548 New function SSL_CTX_set_default_passwd_cb_userdata.
550 Compatibility note: As many C implementations push function arguments
551 onto the stack in reverse order, the new library version is likely to
552 interoperate with programs that have been compiled with the old
553 pem_password_cb definition (PEM_whatever takes some data that
554 happens to be on the stack as its last argument, and the callback
555 just ignores this garbage); but there is no guarantee whatsoever that
558 *) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=...
559 (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused
560 problems not only on Windows, but also on some Unix platforms.
561 To avoid problematic command lines, these definitions are now in an
562 auto-generated file crypto/buildinf.h (created by crypto/Makefile.ssl
563 for standard "make" builds, by util/mk1mf.pl for "mk1mf" builds).
566 *) MIPS III/IV assembler module is reimplemented.
569 *) More DES library cleanups: remove references to srand/rand and
570 delete an unused file.
573 *) Add support for the the free Netwide assembler (NASM) under Win32,
574 since not many people have MASM (ml) and it can be hard to obtain.
575 This is currently experimental but it seems to work OK and pass all
576 the tests. Check out INSTALL.W32 for info.
579 *) Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections
580 without temporary keys kept an extra copy of the server key,
581 and connections with temporary keys did not free everything in case
585 *) New function RSA_check_key and new openssl rsa option -check
586 for verifying the consistency of RSA keys.
587 [Ulf Moeller, Bodo Moeller]
589 *) Various changes to make Win32 compile work:
590 1. Casts to avoid "loss of data" warnings in p5_crpt2.c
591 2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned
592 comparison" warnings.
593 3. Add sk_<TYPE>_sort to DEF file generator and do make update.
596 *) Add a debugging option to PKCS#5 v2 key generation function: when
597 you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and
598 derived keys are printed to stderr.
601 *) Copy the flags in ASN1_STRING_dup().
602 [Roman E. Pavlov <pre@mo.msk.ru>]
604 *) The x509 application mishandled signing requests containing DSA
605 keys when the signing key was also DSA and the parameters didn't match.
607 It was supposed to omit the parameters when they matched the signing key:
608 the verifying software was then supposed to automatically use the CA's
609 parameters if they were absent from the end user certificate.
611 Omitting parameters is no longer recommended. The test was also
612 the wrong way round! This was probably due to unusual behaviour in
613 EVP_cmp_parameters() which returns 1 if the parameters match.
614 This meant that parameters were omitted when they *didn't* match and
615 the certificate was useless. Certificates signed with 'ca' didn't have
617 [Steve Henson, reported by Doug Erickson <Doug.Erickson@Part.NET>]
619 *) Memory leak checking (-DCRYPTO_MDEBUG) had some problems.
620 The interface is as follows:
622 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(),
623 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop();
624 "off" is now the default.
625 The library internally uses
626 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(),
627 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on()
628 to disable memory-checking temporarily.
630 Some inconsistent states that previously were possible (and were
631 even the default) are now avoided.
633 -DCRYPTO_MDEBUG_TIME is new and additionally stores the current time
634 with each memory chunk allocated; this is occasionally more helpful
635 than just having a counter.
637 -DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID.
639 -DCRYPTO_MDEBUG_ALL enables all of the above, plus any future
643 *) Introduce "mode" for SSL structures (with defaults in SSL_CTX),
644 which largely parallels "options", but is for changing API behaviour,
645 whereas "options" are about protocol behaviour.
646 Initial "mode" flags are:
648 SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when
649 a single record has been written.
650 SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write
651 retries use the same buffer location.
652 (But all of the contents must be
656 *) Bugfix: SSL_set_mode ignored its parameter, only SSL_CTX_set_mode
659 *) Fix problems with no-hmac etc.
660 [Ulf Möller, pointed out by Brian Wellington <bwelling@tislabs.com>]
662 *) New functions RSA_get_default_method(), RSA_set_method() and
663 RSA_get_method(). These allows replacement of RSA_METHODs without having
664 to mess around with the internals of an RSA structure.
667 *) Fix memory leaks in DSA_do_sign and DSA_is_prime.
668 Also really enable memory leak checks in openssl.c and in some
670 [Chad C. Mulligan, Bodo Moeller]
672 *) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess
673 up the length of negative integers. This has now been simplified to just
674 store the length when it is first determined and use it later, rather
675 than trying to keep track of where data is copied and updating it to
677 [Steve Henson, reported by Brien Wheeler
678 <bwheeler@authentica-security.com>]
680 *) Add a new function PKCS7_signatureVerify. This allows the verification
681 of a PKCS#7 signature but with the signing certificate passed to the
682 function itself. This contrasts with PKCS7_dataVerify which assumes the
683 certificate is present in the PKCS#7 structure. This isn't always the
684 case: certificates can be omitted from a PKCS#7 structure and be
685 distributed by "out of band" means (such as a certificate database).
688 *) Complete the PEM_* macros with DECLARE_PEM versions to replace the
689 function prototypes in pem.h, also change util/mkdef.pl to add the
690 necessary function names.
693 *) mk1mf.pl (used by Windows builds) did not properly read the
694 options set by Configure in the top level Makefile, and Configure
695 was not even able to write more than one option correctly.
696 Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended.
699 *) New functions CONF_load_bio() and CONF_load_fp() to allow a config
700 file to be loaded from a BIO or FILE pointer. The BIO version will
701 for example allow memory BIOs to contain config info.
704 *) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS.
705 Whoever hopes to achieve shared-library compatibility across versions
706 must use this, not the compile-time macro.
707 (Exercise 0.9.4: Which is the minimum library version required by
709 Note: All this applies only to multi-threaded programs, others don't
713 *) Add missing case to s3_clnt.c state machine -- one of the new SSL tests
714 through a BIO pair triggered the default case, i.e.
715 SSLerr(...,SSL_R_UNKNOWN_STATE).
718 *) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications
719 can use the SSL library even if none of the specific BIOs is
723 *) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value
724 for the encoded length.
725 [Jeon KyoungHo <khjeon@sds.samsung.co.kr>]
727 *) Add initial documentation of the X509V3 functions.
730 *) Add a new pair of functions PEM_write_PKCS8PrivateKey() and
731 PEM_write_bio_PKCS8PrivateKey() that are equivalent to
732 PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more
733 secure PKCS#8 private key format with a high iteration count.
736 *) Fix determination of Perl interpreter: A perl or perl5
737 _directory_ in $PATH was also accepted as the interpreter.
738 [Ralf S. Engelschall]
740 *) Fix demos/sign/sign.c: well there wasn't anything strictly speaking
741 wrong with it but it was very old and did things like calling
742 PEM_ASN1_read() directly and used MD5 for the hash not to mention some
746 *) Fix demos/selfsign.c: it used obsolete and deleted functions, changed
747 to use the new extension code.
750 *) Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c
751 with macros. This should make it easier to change their form, add extra
752 arguments etc. Fix a few PEM prototypes which didn't have cipher as a
756 *) Add to configuration table a new entry that can specify an alternative
757 name for unistd.h (for pre-POSIX systems); we need this for NeXTstep,
758 according to Mark Crispin <MRC@Panda.COM>.
762 *) DES CBC did not update the IV. Weird.
765 des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does.
766 Changing the behaviour of the former might break existing programs --
767 where IV updating is needed, des_ncbc_encrypt can be used.
770 *) When bntest is run from "make test" it drives bc to check its
771 calculations, as well as internally checking them. If an internal check
772 fails, it needs to cause bc to give a non-zero result or make test carries
773 on without noticing the failure. Fixed.
776 *) DES library cleanups.
779 *) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be
780 used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit
781 ciphers. NOTE: although the key derivation function has been verified
782 against some published test vectors it has not been extensively tested
783 yet. Added a -v2 "cipher" option to pkcs8 application to allow the use
787 *) Instead of "mkdir -p", which is not fully portable, use new
788 Perl script "util/mkdir-p.pl".
791 *) Rewrite the way password based encryption (PBE) is handled. It used to
792 assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter
793 structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms
794 but doesn't apply to PKCS#5 v2.0 where it can be something else. Now
795 the 'parameter' field of the AlgorithmIdentifier is passed to the
796 underlying key generation function so it must do its own ASN1 parsing.
797 This has also changed the EVP_PBE_CipherInit() function which now has a
798 'parameter' argument instead of literal salt and iteration count values
799 and the function EVP_PBE_ALGOR_CipherInit() has been deleted.
802 *) Support for PKCS#5 v1.5 compatible password based encryption algorithms
803 and PKCS#8 functionality. New 'pkcs8' application linked to openssl.
804 Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE
805 KEY" because this clashed with PKCS#8 unencrypted string. Since this
806 value was just used as a "magic string" and not used directly its
807 value doesn't matter.
810 *) Introduce some semblance of const correctness to BN. Shame C doesn't
814 *) "linux-sparc64" configuration (ultrapenguin).
815 [Ray Miller <ray.miller@oucs.ox.ac.uk>]
816 "linux-sparc" configuration.
817 [Christian Forster <fo@hawo.stw.uni-erlangen.de>]
819 *) config now generates no-xxx options for missing ciphers.
822 *) Support the EBCDIC character set (work in progress).
823 File ebcdic.c not yet included because it has a different license.
824 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
826 *) Support BS2000/OSD-POSIX.
827 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
829 *) Make callbacks for key generation use void * instead of char *.
832 *) Make S/MIME samples compile (not yet tested).
835 *) Additional typesafe stacks.
838 *) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x).
842 Changes between 0.9.3 and 0.9.3a [29 May 1999]
844 *) New configuration variant "sco5-gcc".
846 *) Updated some demos.
847 [Sean O Riordain, Wade Scholine]
849 *) Add missing BIO_free at exit of pkcs12 application.
852 *) Fix memory leak in conf.c.
855 *) Updates for Win32 to assembler version of MD5.
858 *) Set #! path to perl in apps/der_chop to where we found it
859 instead of using a fixed path.
862 *) SHA library changes for irix64-mips4-cc.
865 *) Improvements for VMS support.
869 Changes between 0.9.2b and 0.9.3 [24 May 1999]
871 *) Bignum library bug fix. IRIX 6 passes "make test" now!
872 This also avoids the problems with SC4.2 and unpatched SC5.
873 [Andy Polyakov <appro@fy.chalmers.se>]
875 *) New functions sk_num, sk_value and sk_set to replace the previous macros.
876 These are required because of the typesafe stack would otherwise break
877 existing code. If old code used a structure member which used to be STACK
878 and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with
879 sk_num or sk_value it would produce an error because the num, data members
880 are not present in STACK_OF. Now it just produces a warning. sk_set
881 replaces the old method of assigning a value to sk_value
882 (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code
883 that does this will no longer work (and should use sk_set instead) but
884 this could be regarded as a "questionable" behaviour anyway.
887 *) Fix most of the other PKCS#7 bugs. The "experimental" code can now
888 correctly handle encrypted S/MIME data.
891 *) Change type of various DES function arguments from des_cblock
892 (which means, in function argument declarations, pointer to char)
893 to des_cblock * (meaning pointer to array with 8 char elements),
894 which allows the compiler to do more typechecking; it was like
895 that back in SSLeay, but with lots of ugly casts.
897 Introduce new type const_des_cblock.
900 *) Reorganise the PKCS#7 library and get rid of some of the more obvious
901 problems: find RecipientInfo structure that matches recipient certificate
902 and initialise the ASN1 structures properly based on passed cipher.
905 *) Belatedly make the BN tests actually check the results.
908 *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion
909 to and from BNs: it was completely broken. New compilation option
910 NEG_PUBKEY_BUG to allow for some broken certificates that encode public
911 key elements as negative integers.
914 *) Reorganize and speed up MD5.
915 [Andy Polyakov <appro@fy.chalmers.se>]
918 [Richard Levitte <richard@levitte.org>]
920 *) New option -out to asn1parse to allow the parsed structure to be
921 output to a file. This is most useful when combined with the -strparse
922 option to examine the output of things like OCTET STRINGS.
925 *) Make SSL library a little more fool-proof by not requiring any longer
926 that SSL_set_{accept,connect}_state be called before
927 SSL_{accept,connect} may be used (SSL_set_..._state is omitted
928 in many applications because usually everything *appeared* to work as
929 intended anyway -- now it really works as intended).
932 *) Move openssl.cnf out of lib/.
935 *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall
936 -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
937 -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+
938 [Ralf S. Engelschall]
940 *) Various fixes to the EVP and PKCS#7 code. It may now be able to
941 handle PKCS#7 enveloped data properly.
942 [Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve]
944 *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
945 copying pointers. The cert_st handling is changed by this in
946 various ways (and thus what used to be known as ctx->default_cert
947 is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
948 any longer when s->cert does not give us what we need).
949 ssl_cert_instantiate becomes obsolete by this change.
950 As soon as we've got the new code right (possibly it already is?),
951 we have solved a couple of bugs of the earlier code where s->cert
952 was used as if it could not have been shared with other SSL structures.
954 Note that using the SSL API in certain dirty ways now will result
955 in different behaviour than observed with earlier library versions:
956 Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
957 does not influence s as it used to.
959 In order to clean up things more thoroughly, inside SSL_SESSION
960 we don't use CERT any longer, but a new structure SESS_CERT
961 that holds per-session data (if available); currently, this is
962 the peer's certificate chain and, for clients, the server's certificate
963 and temporary key. CERT holds only those values that can have
964 meaningful defaults in an SSL_CTX.
967 *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure
968 from the internal representation. Various PKCS#7 fixes: remove some
969 evil casts and set the enc_dig_alg field properly based on the signing
973 *) Allow PKCS#12 password to be set from the command line or the
974 environment. Let 'ca' get its config file name from the environment
975 variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req'
979 *) Allow certificate policies extension to use an IA5STRING for the
980 organization field. This is contrary to the PKIX definition but
981 VeriSign uses it and IE5 only recognises this form. Document 'x509'
985 *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic,
986 without disallowing inline assembler and the like for non-pedantic builds.
989 *) Support Borland C++ builder.
990 [Janez Jere <jj@void.si>, modified by Ulf Möller]
995 *) SHA-1 cleanups and performance enhancements.
996 [Andy Polyakov <appro@fy.chalmers.se>]
998 *) Sparc v8plus assembler for the bignum library.
999 [Andy Polyakov <appro@fy.chalmers.se>]
1001 *) Accept any -xxx and +xxx compiler options in Configure.
1004 *) Update HPUX configuration.
1007 *) Add missing sk_<type>_unshift() function to safestack.h
1008 [Ralf S. Engelschall]
1010 *) New function SSL_CTX_use_certificate_chain_file that sets the
1011 "extra_cert"s in addition to the certificate. (This makes sense
1012 only for "PEM" format files, as chains as a whole are not
1016 *) Support verify_depth from the SSL API.
1017 x509_vfy.c had what can be considered an off-by-one-error:
1018 Its depth (which was not part of the external interface)
1019 was actually counting the number of certificates in a chain;
1020 now it really counts the depth.
1023 *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used
1024 instead of X509err, which often resulted in confusing error
1025 messages since the error codes are not globally unique
1026 (e.g. an alleged error in ssl3_accept when a certificate
1027 didn't match the private key).
1029 *) New function SSL_CTX_set_session_id_context that allows to set a default
1030 value (so that you don't need SSL_set_session_id_context for each
1031 connection using the SSL_CTX).
1034 *) OAEP decoding bug fix.
1037 *) Support INSTALL_PREFIX for package builders, as proposed by
1041 *) New Configure options "threads" and "no-threads". For systems
1042 where the proper compiler options are known (currently Solaris
1043 and Linux), "threads" is the default.
1046 *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
1049 *) Install various scripts to $(OPENSSLDIR)/misc, not to
1050 $(INSTALLTOP)/bin -- they shouldn't clutter directories
1051 such as /usr/local/bin.
1054 *) "make linux-shared" to build shared libraries.
1055 [Niels Poppe <niels@netbox.org>]
1057 *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
1060 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
1061 extension adding in x509 utility.
1064 *) Remove NOPROTO sections and error code comments.
1067 *) Partial rewrite of the DEF file generator to now parse the ANSI
1071 *) New Configure options --prefix=DIR and --openssldir=DIR.
1074 *) Complete rewrite of the error code script(s). It is all now handled
1075 by one script at the top level which handles error code gathering,
1076 header rewriting and C source file generation. It should be much better
1077 than the old method: it now uses a modified version of Ulf's parser to
1078 read the ANSI prototypes in all header files (thus the old K&R definitions
1079 aren't needed for error creation any more) and do a better job of
1080 translating function codes into names. The old 'ASN1 error code imbedded
1081 in a comment' is no longer necessary and it doesn't use .err files which
1082 have now been deleted. Also the error code call doesn't have to appear all
1083 on one line (which resulted in some large lines...).
1086 *) Change #include filenames from <foo.h> to <openssl/foo.h>.
1089 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
1090 0 (which usually indicates a closed connection), but continue reading.
1093 *) Fix some race conditions.
1096 *) Add support for CRL distribution points extension. Add Certificate
1097 Policies and CRL distribution points documentation.
1100 *) Move the autogenerated header file parts to crypto/opensslconf.h.
1103 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
1104 8 of keying material. Merlin has also confirmed interop with this fix
1105 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
1106 [Merlin Hughes <merlin@baltimore.ie>]
1108 *) Fix lots of warnings.
1109 [Richard Levitte <levitte@stacken.kth.se>]
1111 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
1112 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
1113 [Richard Levitte <levitte@stacken.kth.se>]
1115 *) Fix problems with sizeof(long) == 8.
1116 [Andy Polyakov <appro@fy.chalmers.se>]
1118 *) Change functions to ANSI C.
1121 *) Fix typos in error codes.
1122 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
1124 *) Remove defunct assembler files from Configure.
1127 *) SPARC v8 assembler BIGNUM implementation.
1128 [Andy Polyakov <appro@fy.chalmers.se>]
1130 *) Support for Certificate Policies extension: both print and set.
1131 Various additions to support the r2i method this uses.
1134 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
1135 return a const string when you are expecting an allocated buffer.
1138 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
1139 types DirectoryString and DisplayText.
1142 *) Add code to allow r2i extensions to access the configuration database,
1143 add an LHASH database driver and add several ctx helper functions.
1146 *) Fix an evil bug in bn_expand2() which caused various BN functions to
1147 fail when they extended the size of a BIGNUM.
1150 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
1151 support typesafe stack.
1154 *) Fix typo in SSL_[gs]et_options().
1155 [Nils Frostberg <nils@medcom.se>]
1157 *) Delete various functions and files that belonged to the (now obsolete)
1158 old X509V3 handling code.
1161 *) New Configure option "rsaref".
1164 *) Don't auto-generate pem.h.
1167 *) Introduce type-safe ASN.1 SETs.
1170 *) Convert various additional casted stacks to type-safe STACK_OF() variants.
1171 [Ben Laurie, Ralf S. Engelschall, Steve Henson]
1173 *) Introduce type-safe STACKs. This will almost certainly break lots of code
1174 that links with OpenSSL (well at least cause lots of warnings), but fear
1175 not: the conversion is trivial, and it eliminates loads of evil casts. A
1176 few STACKed things have been converted already. Feel free to convert more.
1177 In the fullness of time, I'll do away with the STACK type altogether.
1180 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
1181 specified in <certfile> by updating the entry in the index.txt file.
1182 This way one no longer has to edit the index.txt file manually for
1183 revoking a certificate. The -revoke option does the gory details now.
1184 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
1186 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
1187 `-text' option at all and this way the `-noout -text' combination was
1188 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
1189 [Ralf S. Engelschall]
1191 *) Make sure a corresponding plain text error message exists for the
1192 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
1193 verify callback function determined that a certificate was revoked.
1194 [Ralf S. Engelschall]
1196 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
1197 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
1198 all available cipers including rc5, which was forgotten until now.
1199 In order to let the testing shell script know which algorithms
1200 are available, a new (up to now undocumented) command
1201 "openssl list-cipher-commands" is used.
1204 *) Bugfix: s_client occasionally would sleep in select() when
1205 it should have checked SSL_pending() first.
1208 *) New functions DSA_do_sign and DSA_do_verify to provide access to
1209 the raw DSA values prior to ASN.1 encoding.
1212 *) Tweaks to Configure
1213 [Niels Poppe <niels@netbox.org>]
1215 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
1219 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
1222 *) New config option to avoid instructions that are illegal on the 80386.
1223 The default code is faster, but requires at least a 486.
1226 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
1227 SSL2_SERVER_VERSION (not used at all) macros, which are now the
1228 same as SSL2_VERSION anyway.
1231 *) New "-showcerts" option for s_client.
1234 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
1235 application. Various cleanups and fixes.
1238 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
1239 modify error routines to work internally. Add error codes and PBE init
1240 to library startup routines.
1243 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
1244 packing functions to asn1 and evp. Changed function names and error
1245 codes along the way.
1248 *) PKCS12 integration: and so it begins... First of several patches to
1249 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
1250 objects to objects.h
1253 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
1254 and display support for Thawte strong extranet extension.
1257 *) Add LinuxPPC support.
1258 [Jeff Dubrule <igor@pobox.org>]
1260 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
1261 bn_div_words in alpha.s.
1262 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
1264 *) Make sure the RSA OAEP test is skipped under -DRSAref because
1265 OAEP isn't supported when OpenSSL is built with RSAref.
1266 [Ulf Moeller <ulf@fitug.de>]
1268 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
1269 so they no longer are missing under -DNOPROTO.
1270 [Soren S. Jorvang <soren@t.dk>]
1273 Changes between 0.9.1c and 0.9.2b [22 Mar 1999]
1275 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
1276 doesn't work when the session is reused. Coming soon!
1279 *) Fix a security hole, that allows sessions to be reused in the wrong
1280 context thus bypassing client cert protection! All software that uses
1281 client certs and session caches in multiple contexts NEEDS PATCHING to
1282 allow session reuse! A fuller solution is in the works.
1283 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
1285 *) Some more source tree cleanups (removed obsolete files
1286 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
1287 permission on "config" script to be executable) and a fix for the INSTALL
1289 [Ulf Moeller <ulf@fitug.de>]
1291 *) Remove some legacy and erroneous uses of malloc, free instead of
1293 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
1295 *) Make rsa_oaep_test return non-zero on error.
1296 [Ulf Moeller <ulf@fitug.de>]
1298 *) Add support for native Solaris shared libraries. Configure
1299 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
1300 if someone would make that last step automatic.
1301 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
1303 *) ctx_size was not built with the right compiler during "make links". Fixed.
1306 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
1307 except NULL ciphers". This means the default cipher list will no longer
1308 enable NULL ciphers. They need to be specifically enabled e.g. with
1309 the string "DEFAULT:eNULL".
1312 *) Fix to RSA private encryption routines: if p < q then it would
1313 occasionally produce an invalid result. This will only happen with
1314 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
1317 *) Be less restrictive and allow also `perl util/perlpath.pl
1318 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
1319 because this way one can also use an interpreter named `perl5' (which is
1320 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
1321 installed as `perl').
1322 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
1324 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
1325 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
1327 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
1328 advapi32.lib to Win32 build and change the pem test comparision
1329 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
1330 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
1331 and crypto/des/ede_cbcm_enc.c.
1334 *) DES quad checksum was broken on big-endian architectures. Fixed.
1337 *) Comment out two functions in bio.h that aren't implemented. Fix up the
1338 Win32 test batch file so it (might) work again. The Win32 test batch file
1339 is horrible: I feel ill....
1342 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
1343 in e_os.h. Audit of header files to check ANSI and non ANSI
1344 sections: 10 functions were absent from non ANSI section and not exported
1345 from Windows DLLs. Fixed up libeay.num for new functions.
1348 *) Make `openssl version' output lines consistent.
1349 [Ralf S. Engelschall]
1351 *) Fix Win32 symbol export lists for BIO functions: Added
1352 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
1353 to ms/libeay{16,32}.def.
1354 [Ralf S. Engelschall]
1356 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
1357 fine under Unix and passes some trivial tests I've now added. But the
1358 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
1359 added to make sure no one expects that this stuff really works in the
1360 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
1361 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
1363 [Ralf S. Engelschall]
1365 *) Fix the generation of two part addresses in perl.
1366 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
1368 *) Add config entry for Linux on MIPS.
1369 [John Tobey <jtobey@channel1.com>]
1371 *) Make links whenever Configure is run, unless we are on Windoze.
1374 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
1375 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
1379 *) Add a useful kludge to allow package maintainers to specify compiler and
1380 other platforms details on the command line without having to patch the
1381 Configure script everytime: One now can use ``perl Configure
1382 <id>:<details>'', i.e. platform ids are allowed to have details appended
1383 to them (seperated by colons). This is treated as there would be a static
1384 pre-configured entry in Configure's %table under key <id> with value
1385 <details> and ``perl Configure <id>'' is called. So, when you want to
1386 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
1387 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
1388 now, which overrides the FreeBSD-elf entry on-the-fly.
1389 [Ralf S. Engelschall]
1391 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
1394 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
1395 on the `perl Configure ...' command line. This way one can compile
1396 OpenSSL libraries with Position Independent Code (PIC) which is needed
1397 for linking it into DSOs.
1398 [Ralf S. Engelschall]
1400 *) Remarkably, export ciphers were totally broken and no-one had noticed!
1404 *) Cleaned up the LICENSE document: The official contact for any license
1405 questions now is the OpenSSL core team under openssl-core@openssl.org.
1406 And add a paragraph about the dual-license situation to make sure people
1407 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
1408 to the OpenSSL toolkit.
1409 [Ralf S. Engelschall]
1411 *) General source tree makefile cleanups: Made `making xxx in yyy...'
1412 display consistent in the source tree and replaced `/bin/rm' by `rm'.
1413 Additonally cleaned up the `make links' target: Remove unnecessary
1414 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
1415 to speed processing and no longer clutter the display with confusing
1416 stuff. Instead only the actually done links are displayed.
1417 [Ralf S. Engelschall]
1419 *) Permit null encryption ciphersuites, used for authentication only. It used
1420 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
1421 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
1425 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
1426 signed attributes when verifying signatures (this would break them),
1427 the detached data encoding was wrong and public keys obtained using
1428 X509_get_pubkey() weren't freed.
1431 *) Add text documentation for the BUFFER functions. Also added a work around
1432 to a Win95 console bug. This was triggered by the password read stuff: the
1433 last character typed gets carried over to the next fread(). If you were
1434 generating a new cert request using 'req' for example then the last
1435 character of the passphrase would be CR which would then enter the first
1439 *) Added the new `Includes OpenSSL Cryptography Software' button as
1440 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
1441 button and can be used by applications based on OpenSSL to show the
1442 relationship to the OpenSSL project.
1443 [Ralf S. Engelschall]
1445 *) Remove confusing variables in function signatures in files
1446 ssl/ssl_lib.c and ssl/ssl.h.
1447 [Lennart Bong <lob@kulthea.stacken.kth.se>]
1449 *) Don't install bss_file.c under PREFIX/include/
1450 [Lennart Bong <lob@kulthea.stacken.kth.se>]
1452 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
1453 functions that return function pointers and has support for NT specific
1454 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
1455 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
1456 unsigned to signed types: this was killing the Win32 compile.
1459 *) Add new certificate file to stack functions,
1460 SSL_add_dir_cert_subjects_to_stack() and
1461 SSL_add_file_cert_subjects_to_stack(). These largely supplant
1462 SSL_load_client_CA_file(), and can be used to add multiple certs easily
1463 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
1464 This means that Apache-SSL and similar packages don't have to mess around
1465 to add as many CAs as they want to the preferred list.
1468 *) Experiment with doxygen documentation. Currently only partially applied to
1470 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
1471 openssl.doxy as the configuration file.
1474 *) Get rid of remaining C++-style comments which strict C compilers hate.
1475 [Ralf S. Engelschall, pointed out by Carlos Amengual]
1477 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
1478 compiled in by default: it has problems with large keys.
1481 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
1482 DH private keys and/or callback functions which directly correspond to
1483 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
1484 is needed for applications which have to configure certificates on a
1485 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
1487 For the RSA certificate situation is makes no difference, but
1488 for the DSA certificate situation this fixes the "no shared cipher"
1489 problem where the OpenSSL cipher selection procedure failed because the
1490 temporary keys were not overtaken from the context and the API provided
1491 no way to reconfigure them.
1492 The new functions now let applications reconfigure the stuff and they
1493 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
1494 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
1495 non-public-API function ssl_cert_instantiate() is used as a helper
1496 function and also to reduce code redundancy inside ssl_rsa.c.
1497 [Ralf S. Engelschall]
1499 *) Move s_server -dcert and -dkey options out of the undocumented feature
1500 area because they are useful for the DSA situation and should be
1501 recognized by the users.
1502 [Ralf S. Engelschall]
1504 *) Fix the cipher decision scheme for export ciphers: the export bits are
1505 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
1506 SSL_EXP_MASK. So, the original variable has to be used instead of the
1507 already masked variable.
1508 [Richard Levitte <levitte@stacken.kth.se>]
1510 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
1511 [Richard Levitte <levitte@stacken.kth.se>]
1513 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
1514 from `int' to `unsigned int' because it's a length and initialized by
1515 EVP_DigestFinal() which expects an `unsigned int *'.
1516 [Richard Levitte <levitte@stacken.kth.se>]
1518 *) Don't hard-code path to Perl interpreter on shebang line of Configure
1519 script. Instead use the usual Shell->Perl transition trick.
1520 [Ralf S. Engelschall]
1522 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
1523 (in addition to RSA certificates) to match the behaviour of `openssl dsa
1524 -noout -modulus' as it's already the case for `openssl rsa -noout
1525 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
1526 currently the public key is printed (a decision which was already done by
1527 `openssl dsa -modulus' in the past) which serves a similar purpose.
1528 Additionally the NO_RSA no longer completely removes the whole -modulus
1529 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
1531 [Ralf S. Engelschall]
1533 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
1534 BIO. See the source (crypto/evp/bio_ok.c) for more info.
1535 [Arne Ansper <arne@ats.cyber.ee>]
1537 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
1538 to be added. Now both 'req' and 'ca' can use new objects defined in the
1542 *) Add cool BIO that does syslog (or event log on NT).
1543 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
1545 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
1546 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
1547 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
1548 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
1551 *) Add preliminary config info for new extension code.
1554 *) Make RSA_NO_PADDING really use no padding.
1555 [Ulf Moeller <ulf@fitug.de>]
1557 *) Generate errors when private/public key check is done.
1560 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
1561 for some CRL extensions and new objects added.
1564 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
1565 key usage extension and fuller support for authority key id.
1568 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
1569 padding method for RSA, which is recommended for new applications in PKCS
1570 #1 v2.0 (RFC 2437, October 1998).
1571 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
1572 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
1573 against Bleichbacher's attack on RSA.
1574 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
1577 *) Updates to the new SSL compression code
1578 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
1580 *) Fix so that the version number in the master secret, when passed
1581 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
1582 (because the server will not accept higher), that the version number
1583 is 0x03,0x01, not 0x03,0x00
1584 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
1586 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
1587 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
1588 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
1591 *) Support for RAW extensions where an arbitrary extension can be
1592 created by including its DER encoding. See apps/openssl.cnf for
1596 *) Make sure latest Perl versions don't interpret some generated C array
1597 code as Perl array code in the crypto/err/err_genc.pl script.
1598 [Lars Weber <3weber@informatik.uni-hamburg.de>]
1600 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
1601 not many people have the assembler. Various Win32 compilation fixes and
1602 update to the INSTALL.W32 file with (hopefully) more accurate Win32
1606 *) Modify configure script 'Configure' to automatically create crypto/date.h
1607 file under Win32 and also build pem.h from pem.org. New script
1608 util/mkfiles.pl to create the MINFO file on environments that can't do a
1609 'make files': perl util/mkfiles.pl >MINFO should work.
1612 *) Major rework of DES function declarations, in the pursuit of correctness
1613 and purity. As a result, many evil casts evaporated, and some weirdness,
1614 too. You may find this causes warnings in your code. Zapping your evil
1615 casts will probably fix them. Mostly.
1618 *) Fix for a typo in asn1.h. Bug fix to object creation script
1619 obj_dat.pl. It considered a zero in an object definition to mean
1620 "end of object": none of the objects in objects.h have any zeros
1621 so it wasn't spotted.
1622 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
1624 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
1625 Masking (CBCM). In the absence of test vectors, the best I have been able
1626 to do is check that the decrypt undoes the encrypt, so far. Send me test
1627 vectors if you have them.
1630 *) Correct calculation of key length for export ciphers (too much space was
1631 allocated for null ciphers). This has not been tested!
1634 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
1635 message is now correct (it understands "crypto" and "ssl" on its
1636 command line). There is also now an "update" option. This will update
1637 the util/ssleay.num and util/libeay.num files with any new functions.
1639 perl util/mkdef.pl crypto ssl update
1640 it will update them.
1643 *) Overhauled the Perl interface (perl/*):
1644 - ported BN stuff to OpenSSL's different BN library
1645 - made the perl/ source tree CVS-aware
1646 - renamed the package from SSLeay to OpenSSL (the files still contain
1647 their history because I've copied them in the repository)
1648 - removed obsolete files (the test scripts will be replaced
1649 by better Test::Harness variants in the future)
1650 [Ralf S. Engelschall]
1652 *) First cut for a very conservative source tree cleanup:
1653 1. merge various obsolete readme texts into doc/ssleay.txt
1654 where we collect the old documents and readme texts.
1655 2. remove the first part of files where I'm already sure that we no
1656 longer need them because of three reasons: either they are just temporary
1657 files which were left by Eric or they are preserved original files where
1658 I've verified that the diff is also available in the CVS via "cvs diff
1659 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
1660 the crypto/md/ stuff).
1661 [Ralf S. Engelschall]
1663 *) More extension code. Incomplete support for subject and issuer alt
1664 name, issuer and authority key id. Change the i2v function parameters
1665 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
1666 what that's for :-) Fix to ASN1 macro which messed up
1667 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
1670 *) Preliminary support for ENUMERATED type. This is largely copied from the
1674 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
1675 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
1677 *) Make sure `make rehash' target really finds the `openssl' program.
1678 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
1680 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
1681 like to hear about it if this slows down other processors.
1684 *) Add CygWin32 platform information to Configure script.
1685 [Alan Batie <batie@aahz.jf.intel.com>]
1687 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
1688 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
1690 *) New program nseq to manipulate netscape certificate sequences
1693 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
1697 *) Fixes to BN code. Previously the default was to define BN_RECURSION
1698 but the BN code had some problems that would cause failures when
1699 doing certificate verification and some other functions.
1700 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
1702 *) Add ASN1 and PEM code to support netscape certificate sequences.
1705 *) Add ASN1 and PEM code to support netscape certificate sequences.
1708 *) Add several PKIX and private extended key usage OIDs.
1711 *) Modify the 'ca' program to handle the new extension code. Modify
1712 openssl.cnf for new extension format, add comments.
1715 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
1716 and add a sample to openssl.cnf so req -x509 now adds appropriate
1720 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
1721 error code, add initial support to X509_print() and x509 application.
1724 *) Takes a deep breath and start addding X509 V3 extension support code. Add
1725 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
1726 stuff is currently isolated and isn't even compiled yet.
1729 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
1730 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
1731 Removed the versions check from X509 routines when loading extensions:
1732 this allows certain broken certificates that don't set the version
1733 properly to be processed.
1736 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
1737 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
1738 can still be regenerated with "make depend".
1741 *) Spelling mistake in C version of CAST-128.
1742 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
1744 *) Changes to the error generation code. The perl script err-code.pl
1745 now reads in the old error codes and retains the old numbers, only
1746 adding new ones if necessary. It also only changes the .err files if new
1747 codes are added. The makefiles have been modified to only insert errors
1748 when needed (to avoid needlessly modifying header files). This is done
1749 by only inserting errors if the .err file is newer than the auto generated
1750 C file. To rebuild all the error codes from scratch (the old behaviour)
1751 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
1752 or delete all the .err files.
1755 *) CAST-128 was incorrectly implemented for short keys. The C version has
1756 been fixed, but is untested. The assembler versions are also fixed, but
1757 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
1758 to regenerate it if needed.
1759 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
1760 Hagino <itojun@kame.net>]
1762 *) File was opened incorrectly in randfile.c.
1763 [Ulf Möller <ulf@fitug.de>]
1765 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
1766 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
1767 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
1768 al: it's just almost always a UTCTime. Note this patch adds new error
1769 codes so do a "make errors" if there are problems.
1772 *) Correct Linux 1 recognition in config.
1773 [Ulf Möller <ulf@fitug.de>]
1775 *) Remove pointless MD5 hash when using DSA keys in ca.
1776 [Anonymous <nobody@replay.com>]
1778 *) Generate an error if given an empty string as a cert directory. Also
1779 generate an error if handed NULL (previously returned 0 to indicate an
1780 error, but didn't set one).
1781 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
1783 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
1786 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
1787 parameters. This was causing a warning which killed off the Win32 compile.
1790 *) Remove C++ style comments from crypto/bn/bn_local.h.
1791 [Neil Costigan <neil.costigan@celocom.com>]
1793 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
1794 based on a text string, looking up short and long names and finally
1795 "dot" format. The "dot" format stuff didn't work. Added new function
1796 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
1797 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
1798 OID is not part of the table.
1801 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
1802 X509_LOOKUP_by_alias().
1805 *) Sort openssl functions by name.
1808 *) Get the gendsa program working (hopefully) and add it to app list. Remove
1809 encryption from sample DSA keys (in case anyone is interested the password
1813 *) Make _all_ *_free functions accept a NULL pointer.
1814 [Frans Heymans <fheymans@isaserver.be>]
1816 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
1818 [Anonymous <nobody@replay.com>]
1820 *) s_server should send the CAfile as acceptable CAs, not its own cert.
1821 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
1823 *) Don't blow it for numeric -newkey arguments to apps/req.
1824 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
1826 *) Temp key "for export" tests were wrong in s3_srvr.c.
1827 [Anonymous <nobody@replay.com>]
1829 *) Add prototype for temp key callback functions
1830 SSL_CTX_set_tmp_{rsa,dh}_callback().
1833 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
1834 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
1837 *) X509_name_add_entry() freed the wrong thing after an error.
1838 [Arne Ansper <arne@ats.cyber.ee>]
1840 *) rsa_eay.c would attempt to free a NULL context.
1841 [Arne Ansper <arne@ats.cyber.ee>]
1843 *) BIO_s_socket() had a broken should_retry() on Windoze.
1844 [Arne Ansper <arne@ats.cyber.ee>]
1846 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
1847 [Arne Ansper <arne@ats.cyber.ee>]
1849 *) Make sure the already existing X509_STORE->depth variable is initialized
1850 in X509_STORE_new(), but document the fact that this variable is still
1851 unused in the certificate verification process.
1852 [Ralf S. Engelschall]
1854 *) Fix the various library and apps files to free up pkeys obtained from
1855 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
1858 *) Fix reference counting in X509_PUBKEY_get(). This makes
1859 demos/maurice/example2.c work, amongst others, probably.
1860 [Steve Henson and Ben Laurie]
1862 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
1863 `openssl' and second, the shortcut symlinks for the `openssl <command>'
1864 are no longer created. This way we have a single and consistent command
1865 line interface `openssl <command>', similar to `cvs <command>'.
1866 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
1868 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
1869 BIT STRING wrapper always have zero unused bits.
1872 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
1875 *) Make the top-level INSTALL documentation easier to understand.
1878 *) Makefiles updated to exit if an error occurs in a sub-directory
1879 make (including if user presses ^C) [Paul Sutton]
1881 *) Make Montgomery context stuff explicit in RSA data structure.
1884 *) Fix build order of pem and err to allow for generated pem.h.
1887 *) Fix renumbering bug in X509_NAME_delete_entry().
1890 *) Enhanced the err-ins.pl script so it makes the error library number
1891 global and can add a library name. This is needed for external ASN1 and
1892 other error libraries.
1895 *) Fixed sk_insert which never worked properly.
1898 *) Fix ASN1 macros so they can handle indefinite length construted
1899 EXPLICIT tags. Some non standard certificates use these: they can now
1903 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
1904 into a single doc/ssleay.txt bundle. This way the information is still
1905 preserved but no longer messes up this directory. Now it's new room for
1906 the new set of documenation files.
1907 [Ralf S. Engelschall]
1909 *) SETs were incorrectly DER encoded. This was a major pain, because they
1910 shared code with SEQUENCEs, which aren't coded the same. This means that
1911 almost everything to do with SETs or SEQUENCEs has either changed name or
1912 number of arguments.
1913 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
1915 *) Fix test data to work with the above.
1918 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
1919 was already fixed by Eric for 0.9.1 it seems.
1920 [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
1922 *) Autodetect FreeBSD3.
1925 *) Fix various bugs in Configure. This affects the following platforms:
1929 unixware-2.0-pentium
1933 *) Eliminate generated files from CVS. Reorder tests to regenerate files
1934 before they are needed.
1937 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
1941 Changes between 0.9.1b and 0.9.1c [23-Dec-1998]
1943 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
1944 changed SSLeay to OpenSSL in version strings.
1945 [Ralf S. Engelschall]
1947 *) Some fixups to the top-level documents.
1950 *) Fixed the nasty bug where rsaref.h was not found under compile-time
1951 because the symlink to include/ was missing.
1952 [Ralf S. Engelschall]
1954 *) Incorporated the popular no-RSA/DSA-only patches
1955 which allow to compile a RSA-free SSLeay.
1956 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
1958 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
1959 when "ssleay" is still not found.
1960 [Ralf S. Engelschall]
1962 *) Added more platforms to Configure: Cray T3E, HPUX 11,
1963 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
1965 *) Updated the README file.
1966 [Ralf S. Engelschall]
1968 *) Added various .cvsignore files in the CVS repository subdirs
1969 to make a "cvs update" really silent.
1970 [Ralf S. Engelschall]
1972 *) Recompiled the error-definition header files and added
1973 missing symbols to the Win32 linker tables.
1974 [Ralf S. Engelschall]
1976 *) Cleaned up the top-level documents;
1977 o new files: CHANGES and LICENSE
1978 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
1979 o merged COPYRIGHT into LICENSE
1980 o removed obsolete TODO file
1981 o renamed MICROSOFT to INSTALL.W32
1982 [Ralf S. Engelschall]
1984 *) Removed dummy files from the 0.9.1b source tree:
1985 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
1986 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f
1987 crypto/pem/gmon.out crypto/perlasm/f crypto/pkcs7/build crypto/rsa/f
1988 crypto/sha/asm/f crypto/threads/f ms/zzz ssl/f ssl/f.mak test/f
1989 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
1990 [Ralf S. Engelschall]
1992 *) Added various platform portability fixes.
1995 *) The Genesis of the OpenSSL rpject:
1996 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
1997 Young and Tim J. Hudson created while they were working for C2Net until
1999 [The OpenSSL Project]
2002 Changes between 0.9.0b and 0.9.1b [not released]
2004 *) Updated a few CA certificates under certs/
2007 *) Changed some BIGNUM api stuff.
2010 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
2011 DGUX x86, Linux Alpha, etc.
2014 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
2015 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
2019 *) Add -strparse option to asn1pars program which parses nested
2021 [Dr Stephen Henson <shenson@bigfoot.com>]
2023 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
2026 *) DSA fix for "ca" program.
2029 *) Added "-genkey" option to "dsaparam" program.
2032 *) Added RIPE MD160 (rmd160) message digest.
2035 *) Added -a (all) option to "ssleay version" command.
2038 *) Added PLATFORM define which is the id given to Configure.
2041 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
2044 *) Extended the ASN.1 parser routines.
2047 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
2050 *) Added a BN_CTX to the BN library.
2053 *) Fixed the weak key values in DES library
2056 *) Changed API in EVP library for cipher aliases.
2059 *) Added support for RC2/64bit cipher.
2062 *) Converted the lhash library to the crypto/mem.c functions.
2065 *) Added more recognized ASN.1 object ids.
2068 *) Added more RSA padding checks for SSL/TLS.
2071 *) Added BIO proxy/filter functionality.
2074 *) Added extra_certs to SSL_CTX which can be used
2075 send extra CA certificates to the client in the CA cert chain sending
2076 process. It can be configured with SSL_CTX_add_extra_chain_cert().
2079 *) Now Fortezza is denied in the authentication phase because
2080 this is key exchange mechanism is not supported by SSLeay at all.
2083 *) Additional PKCS1 checks.
2086 *) Support the string "TLSv1" for all TLS v1 ciphers.
2089 *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
2090 ex_data index of the SSL context in the X509_STORE_CTX ex_data.
2093 *) Fixed a few memory leaks.
2096 *) Fixed various code and comment typos.
2099 *) A minor bug in ssl/s3_clnt.c where there would always be 4 0
2100 bytes sent in the client random.
