5 Changes between 0.9.4 and 0.9.5 [xx XXX 1999]
7 *) The return value of RAND_load_file() no longer counts bytes obtained
8 by stat(). RAND_load_file(..., -1) is new and uses the complete file
9 to seed the PRNG (previously an explicit byte count was required).
10 [Ulf Möller, Bodo Möller]
12 *) Clean up CRYPTO_EX_DATA functions, some of these didn't have prototypes
13 used (char *) instead of (void *) and had casts all over the place.
16 *) Make BN_generate_prime() return NULL on error if ret!=NULL.
19 *) Retain source code compatibility for BN_prime_checks macro.
22 *) Diffie-Hellman uses "safe" primes: DH_check() return code renamed to
23 DH_CHECK_P_NOT_SAFE_PRIME.
24 (Check if this is true? OpenPGP calls them "strong".)
27 *) Merge the functionality of "dh" and "gendh" programs into a new program
28 "dhparam". The old programs are retained for now but will handle DH keys
29 (instead of parameters) in future.
32 *) Make the ciphers, s_server and s_client programs check the return values
33 when a new cipher list is set.
36 *) Enhance the SSL/TLS cipher mechanism to correctly handle the TLS 56bit
37 ciphers. Before when the 56bit ciphers were enabled the sorting was
40 The syntax for the cipher sorting has been extended to support sorting by
41 cipher-strength (using the strength_bits hard coded in the tables).
42 The new command is "@STRENGTH" (see also doc/apps/ciphers.pod).
44 Fix a bug in the cipher-command parser: when supplying a cipher command
45 string with an "undefined" symbol (neither command nor alphanumeric
46 [A-Za-z0-9], ssl_set_cipher_list used to hang in an endless loop. Now
49 Due to the strength-sorting extension, the code of the
50 ssl_create_cipher_list() function was completely rearranged. I hope that
51 the readability was also increased :-)
52 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
54 *) Minor change to 'x509' utility. The -CAcreateserial option now uses 1
55 for the first serial number and places 2 in the serial number file. This
56 avoids problems when the root CA is created with serial number zero and
57 the first user certificate has the same issuer name and serial number
61 *) Fixes to X509_ATTRIBUTE utilities, change the 'req' program so it uses
62 the new code. Add documentation for this stuff.
65 *) Changes to X509_ATTRIBUTE utilities. These have been renamed from
66 X509_*() to X509at_*() on the grounds that they don't handle X509
67 structures and behave in an analagous way to the X509v3 functions:
68 they shouldn't be called directly but wrapper functions should be used
71 So we also now have some wrapper functions that call the X509at functions
72 when passed certificate requests. (TO DO: similar things can be done with
73 PKCS#7 signed and unsigned attributes, PKCS#12 attributes and a few other
74 things. Some of these need some d2i or i2d and print functionality
75 because they handle more complex structures.)
78 *) Add missing #ifndefs that caused missing symbols when building libssl
79 as a shared library without RSA. Use #ifndef NO_SSL2 instead of
81 [Kris Kennaway <kris@hub.freebsd.org>, modified by Ulf Möller]
83 *) Precautions against using the PRNG uninitialized: RAND_bytes() now
84 has a return value which indicates the quality of the random data
85 (1 = ok, 0 = not seeded). Also an error is recorded on the thread's
86 error queue. New function RAND_pseudo_bytes() generates output that is
87 guaranteed to be unique but not unpredictable.
90 *) Do more iterations of Rabin-Miller probable prime test (specifically,
91 3 for 1024-bit primes, 6 for 512-bit primes, 12 for 256-bit primes
92 instead of only 2 for all lengths; see BN_prime_checks_size definition
93 in crypto/bn/bn_prime.c for the complete table). This guarantees a
94 false-positive rate of at most 2^-80 (actually less because we are
95 additionally doing trial division) for random input.
98 *) Rewrite ssl3_read_n (ssl/s3_pkt.c) avoiding a couple of bugs.
101 *) New function X509_CTX_rget_chain(), this returns the chain
102 from an X509_CTX structure with a dup of the stack and all
103 the X509 reference counts upped: so the stack will exist
104 after X509_CTX_cleanup() has been called. Modify pkcs12.c
107 Also make SSL_SESSION_print() print out the verify return
111 *) Add manpage for the pkcs12 command. Also change the default
112 behaviour so MAC iteration counts are used unless the new
113 -nomaciter option is used. This improves file security and
114 only older versions of MSIE (4.0 for example) need it.
117 *) Honor the no-xxx Configure options when creating .DEF files.
120 *) Add PKCS#10 attributes to field table: challengePassword,
121 unstructuredName and unstructuredAddress. These are taken from
122 draft PKCS#9 v2.0 but are compatible with v1.2 provided no
123 international characters are used.
125 More changes to X509_ATTRIBUTE code: allow the setting of types
126 based on strings. Remove the 'loc' parameter when adding
127 attributes because these will be a SET OF encoding which is sorted
131 *) Initial changes to the 'req' utility to allow request generation
132 automation. This will allow an application to just generate a template
133 file containing all the field values and have req construct the
136 Initial support for X509_ATTRIBUTE handling. Stacks of these are
137 used all over the place including certificate requests and PKCS#7
138 structures. They are currently handled manually where necessary with
139 some primitive wrappers for PKCS#7. The new functions behave in a
140 manner analogous to the X509 extension functions: they allow
141 attributes to be looked up by NID and added.
143 Later something similar to the X509V3 code would be desirable to
144 automatically handle the encoding, decoding and printing of the
145 more complex types. The string types like challengePassword can
146 be handled by the string table functions.
148 Also modified the multi byte string table handling. Now there is
149 a 'global mask' which masks out certain types. The table itself
150 can use the flag STABLE_NO_MASK to ignore the mask setting: this
151 is useful when for example there is only one permissible type
152 (as in countryName) and using the mask might result in no valid
156 *) Clean up 'Finished' handling, and add functions SSL_get_finished and
157 SSL_get_peer_finished to allow applications to obtain the latest
158 Finished messages sent to the peer or expected from the peer,
159 respectively. (SSL_get_peer_finished is usually the Finished message
160 actually received from the peer, otherwise the protocol will be aborted.)
162 As the Finished message are message digests of the complete handshake
163 (with a total of 192 bits for TLS 1.0 and more for SSL 3.0), they can
164 be used for external authentication procedures when the authentication
165 provided by SSL/TLS is not desired or is not enough.
168 *) Enhanced support for Alpha Linux is added. Now ./config checks if
169 the host supports BWX extension and if Compaq C is present on the
170 $PATH. Just exploiting of the BWX extension results in 20-30%
171 performance kick for some algorithms, e.g. DES and RC4 to mention
172 a couple. Compaq C in turn generates ~20% faster code for MD5 and
176 *) Add support for MS "fast SGC". This is arguably a violation of the
177 SSL3/TLS protocol. Netscape SGC does two handshakes: the first with
178 weak crypto and after checking the certificate is SGC a second one
179 with strong crypto. MS SGC stops the first handshake after receiving
180 the server certificate message and sends a second client hello. Since
181 a server will typically do all the time consuming operations before
182 expecting any further messages from the client (server key exchange
183 is the most expensive) there is little difference between the two.
185 To get OpenSSL to support MS SGC we have to permit a second client
186 hello message after we have sent server done. In addition we have to
187 reset the MAC if we do get this second client hello and include the
191 *) Add a function 'd2i_AutoPrivateKey()' this will automatically decide
192 if a DER encoded private key is RSA or DSA traditional format. Changed
193 d2i_PrivateKey_bio() to use it. This is only needed for the "traditional"
194 format DER encoded private key. Newer code should use PKCS#8 format which
195 has the key type encoded in the ASN1 structure. Added DER private key
196 support to pkcs8 application.
199 *) SSL 3/TLS 1 servers now don't request certificates when an anonymous
200 ciphersuites has been selected (as required by the SSL 3/TLS 1
201 specifications). Exception: When SSL_VERIFY_FAIL_IF_NO_PEER_CERT
202 is set, we interpret this as a request to violate the specification
203 (the worst that can happen is a handshake failure, and 'correct'
204 behaviour would result in a handshake failure anyway).
207 *) In SSL_CTX_add_session, take into account that there might be multiple
208 SSL_SESSION structures with the same session ID (e.g. when two threads
209 concurrently obtain them from an external cache).
210 The internal cache can handle only one SSL_SESSION with a given ID,
211 so if there's a conflict, we now throw out the old one to achieve
215 *) Add OIDs for idea and blowfish in CBC mode. This will allow both
216 to be used in PKCS#5 v2.0 and S/MIME. Also add checking to
217 some routines that use cipher OIDs: some ciphers do not have OIDs
218 defined and so they cannot be used for S/MIME and PKCS#5 v2.0 for
222 *) Simplify the trust setting structure and code. Now we just have
223 two sequences of OIDs for trusted and rejected settings. These will
224 typically have values the same as the extended key usage extension
225 and any application specific purposes.
227 The trust checking code now has a default behaviour: it will just
228 check for an object with the same NID as the passed id. Functions can
229 be provided to override either the default behaviour or the behaviour
230 for a given id. SSL client, server and email already have functions
231 in place for compatibility: they check the NID and also return "trusted"
232 if the certificate is self signed.
235 *) Add d2i,i2d bio/fp functions for PrivateKey: these convert the
236 traditional format into an EVP_PKEY structure.
239 *) Add a password callback function PEM_cb() which either prompts for
240 a password if usr_data is NULL or otherwise assumes it is a null
241 terminated password. Allow passwords to be passed on command line
242 environment or config files in a few more utilities.
245 *) Add a bunch of DER and PEM functions to handle PKCS#8 format private
246 keys. Add some short names for PKCS#8 PBE algorithms and allow them
247 to be specified on the command line for the pkcs8 and pkcs12 utilities.
248 Update documentation.
251 *) Support for ASN1 "NULL" type. This could be handled before by using
252 ASN1_TYPE but there wasn't any function that would try to read a NULL
253 and produce an error if it couldn't. For compatibility we also have
254 ASN1_NULL_new() and ASN1_NULL_free() functions but these are faked and
255 don't allocate anything because they don't need to.
258 *) Initial support for MacOS is now provided. Examine INSTALL.MacOS
260 [Andy Polyakov, Roy Woods <roy@centicsystems.ca>]
262 *) Rebuild of the memory allocation routines used by OpenSSL code and
263 possibly others as well. The purpose is to make an interface that
264 provide hooks so anyone can build a separate set of allocation and
265 deallocation routines to be used by OpenSSL, for example memory
266 pool implementations, or something else, which was previously hard
267 since Malloc(), Realloc() and Free() were defined as macros having
268 the values malloc, realloc and free, respectively (except for Win32
269 compilations). The same is provided for memory debugging code.
270 OpenSSL already comes with functionality to find memory leaks, but
271 this gives people a chance to debug other memory problems.
273 With these changes, a new set of functions and macros have appeared:
275 CRYPTO_set_mem_debug_functions() [F]
276 CRYPTO_get_mem_debug_functions() [F]
277 CRYPTO_dbg_set_options() [F]
278 CRYPTO_dbg_get_options() [F]
279 CRYPTO_malloc_debug_init() [M]
281 The memory debug functions are NULL by default, unless the library
282 is compiled with CRYPTO_MDEBUG or friends is defined. If someone
283 wants to debug memory anyway, CRYPTO_malloc_debug_init() (which
284 gives the standard debugging functions that come with OpenSSL) or
285 CRYPTO_set_mem_debug_functions() (tells OpenSSL to use functions
286 provided by the library user) must be used. When the standard
287 debugging functions are used, CRYPTO_dbg_set_options can be used to
288 request additional information:
289 CRYPTO_dbg_set_options(V_CYRPTO_MDEBUG_xxx) corresponds to setting
290 the CRYPTO_MDEBUG_xxx macro when compiling the library.
292 Also, things like CRYPTO_set_mem_functions will always give the
293 expected result (the new set of functions is used for allocation
294 and deallocation) at all times, regardless of platform and compiler
297 To finish it up, some functions that were never use in any other
298 way than through macros have a new API and new semantic:
304 All macros of value have retained their old syntax.
305 [Richard Levitte and Bodo Moeller]
307 *) Some S/MIME fixes. The OID for SMIMECapabilities was wrong, the
308 ordering of SMIMECapabilities wasn't in "strength order" and there
309 was a missing NULL in the AlgorithmIdentifier for the SHA1 signature
313 *) Some ASN1 types with illegal zero length encoding (INTEGER,
314 ENUMERATED and OBJECT IDENTIFIER) choked the ASN1 routines.
315 [Frans Heymans <fheymans@isaserver.be>, modified by Steve Henson]
317 *) Merge in my S/MIME library for OpenSSL. This provides a simple
318 S/MIME API on top of the PKCS#7 code, a MIME parser (with enough
319 functionality to handle multipart/signed properly) and a utility
320 called 'smime' to call all this stuff. This is based on code I
321 originally wrote for Celo who have kindly allowed it to be
325 *) Add variants des_set_key_checked and des_set_key_unchecked of
326 des_set_key (aka des_key_sched). Global variable des_check_key
327 decides which of these is called by des_set_key; this way
328 des_check_key behaves as it always did, but applications and
329 the library itself, which was buggy for des_check_key == 1,
330 have a cleaner way to pick the version they need.
333 *) New function PKCS12_newpass() which changes the password of a
337 *) Modify X509_TRUST and X509_PURPOSE so it also uses a static and
338 dynamic mix. In both cases the ids can be used as an index into the
339 table. Also modified the X509_TRUST_add() and X509_PURPOSE_add()
340 functions so they accept a list of the field values and the
341 application doesn't need to directly manipulate the X509_TRUST
345 *) Modify the ASN1_STRING_TABLE stuff so it also uses bsearch and doesn't
349 *) Modify the way the V3 extension code looks up extensions. This now
350 works in a similar way to the object code: we have some "standard"
351 extensions in a static table which is searched with OBJ_bsearch()
352 and the application can add dynamic ones if needed. The file
353 crypto/x509v3/ext_dat.h now has the info: this file needs to be
354 updated whenever a new extension is added to the core code and kept
355 in ext_nid order. There is a simple program 'tabtest.c' which checks
356 this. New extensions are not added too often so this file can readily
357 be maintained manually.
359 There are two big advantages in doing things this way. The extensions
360 can be looked up immediately and no longer need to be "added" using
361 X509V3_add_standard_extensions(): this function now does nothing.
362 [Side note: I get *lots* of email saying the extension code doesn't
363 work because people forget to call this function]
364 Also no dynamic allocation is done unless new extensions are added:
365 so if we don't add custom extensions there is no need to call
366 X509V3_EXT_cleanup().
369 *) Modify enc utility's salting as follows: make salting the default. Add a
370 magic header, so unsalted files fail gracefully instead of just decrypting
371 to garbage. This is because not salting is a big security hole, so people
372 should be discouraged from doing it.
375 *) Fixes and enhancements to the 'x509' utility. It allowed a message
376 digest to be passed on the command line but it only used this
377 parameter when signing a certificate. Modified so all relevant
378 operations are affected by the digest parameter including the
379 -fingerprint and -x509toreq options. Also -x509toreq choked if a
380 DSA key was used because it didn't fix the digest.
383 *) Initial certificate chain verify code. Currently tests the untrusted
384 certificates for consistency with the verify purpose (which is set
385 when the X509_STORE_CTX structure is set up) and checks the pathlength.
387 There is a NO_CHAIN_VERIFY compilation option to keep the old behaviour:
388 this is because it will reject chains with invalid extensions whereas
389 every previous version of OpenSSL and SSLeay made no checks at all.
391 Trust code: checks the root CA for the relevant trust settings. Trust
392 settings have an initial value consistent with the verify purpose: e.g.
393 if the verify purpose is for SSL client use it expects the CA to be
394 trusted for SSL client use. However the default value can be changed to
395 permit custom trust settings: one example of this would be to only trust
396 certificates from a specific "secure" set of CAs.
398 Also added X509_STORE_CTX_new() and X509_STORE_CTX_free() functions
399 which should be used for version portability: especially since the
400 verify structure is likely to change more often now.
402 SSL integration. Add purpose and trust to SSL_CTX and SSL and functions
403 to set them. If not set then assume SSL clients will verify SSL servers
406 Two new options to the verify program: -untrusted allows a set of
407 untrusted certificates to be passed in and -purpose which sets the
408 intended purpose of the certificate. If a purpose is set then the
409 new chain verify code is used to check extension consistency.
412 *) Support for the authority information access extension.
415 *) Modify RSA and DSA PEM read routines to transparently handle
416 PKCS#8 format private keys. New *_PUBKEY_* functions that handle
417 public keys in a format compatible with certificate
418 SubjectPublicKeyInfo structures. Unfortunately there were already
419 functions called *_PublicKey_* which used various odd formats so
420 these are retained for compatibility: however the DSA variants were
421 never in a public release so they have been deleted. Changed dsa/rsa
422 utilities to handle the new format: note no releases ever handled public
423 keys so we should be OK.
425 The primary motivation for this change is to avoid the same fiasco
426 that dogs private keys: there are several incompatible private key
427 formats some of which are standard and some OpenSSL specific and
428 require various evil hacks to allow partial transparent handling and
429 even then it doesn't work with DER formats. Given the option anything
430 other than PKCS#8 should be dumped: but the other formats have to
431 stay in the name of compatibility.
433 With public keys and the benefit of hindsight one standard format
434 is used which works with EVP_PKEY, RSA or DSA structures: though
435 it clearly returns an error if you try to read the wrong kind of key.
437 Added a -pubkey option to the 'x509' utility to output the public key.
438 Also rename the EVP_PKEY_get_*() to EVP_PKEY_rget_*() and add
439 EVP_PKEY_rset_*() functions that do the same as the EVP_PKEY_assign_*()
440 except they up the reference count of the added key (they don't "swallow"
444 *) Fixes to crypto/x509/by_file.c the code to read in certificates and
445 CRLs would fail if the file contained no certificates or no CRLs:
446 added a new function to read in both types and return the number
447 read: this means that if none are read it will be an error. The
448 DER versions of the certificate and CRL reader would always fail
449 because it isn't possible to mix certificates and CRLs in DER format
450 without choking one or the other routine. Changed this to just read
451 a certificate: this is the best we can do. Also modified the code
452 in apps/verify.c to take notice of return codes: it was previously
453 attempting to read in certificates from NULL pointers and ignoring
454 any errors: this is one reason why the cert and CRL reader seemed
455 to work. It doesn't check return codes from the default certificate
456 routines: these may well fail if the certificates aren't installed.
459 *) Code to support otherName option in GeneralName.
462 *) First update to verify code. Change the verify utility
463 so it warns if it is passed a self signed certificate:
464 for consistency with the normal behaviour. X509_verify
465 has been modified to it will now verify a self signed
466 certificate if *exactly* the same certificate appears
467 in the store: it was previously impossible to trust a
468 single self signed certificate. This means that:
469 openssl verify ss.pem
470 now gives a warning about a self signed certificate but
471 openssl verify -CAfile ss.pem ss.pem
475 *) For servers, store verify_result in SSL_SESSION data structure
476 (and add it to external session representation).
477 This is needed when client certificate verifications fails,
478 but an application-provided verification callback (set by
479 SSL_CTX_set_cert_verify_callback) allows accepting the session
480 anyway (i.e. leaves x509_store_ctx->error != X509_V_OK
481 but returns 1): When the session is reused, we have to set
482 ssl->verify_result to the appropriate error code to avoid
484 [Bodo Moeller, problem pointed out by Lutz Jaenicke]
486 *) Fix a bug in the new PKCS#7 code: it didn't consider the
487 case in PKCS7_dataInit() where the signed PKCS7 structure
488 didn't contain any existing data because it was being created.
489 [Po-Cheng Chen <pocheng@nst.com.tw>, slightly modified by Steve Henson]
491 *) Add a salt to the key derivation routines in enc.c. This
492 forms the first 8 bytes of the encrypted file. Also add a
493 -S option to allow a salt to be input on the command line.
496 *) New function X509_cmp(). Oddly enough there wasn't a function
497 to compare two certificates. We do this by working out the SHA1
498 hash and comparing that. X509_cmp() will be needed by the trust
502 *) Correctly increment the reference count in the SSL_SESSION pointer
503 returned from SSL_get_session().
504 [Geoff Thorpe <geoff@eu.c2.net>]
506 *) Fix for 'req': it was adding a null to request attributes.
507 Also change the X509_LOOKUP and X509_INFO code to handle
508 certificate auxiliary information.
511 *) Add support for 40 and 64 bit RC2 and RC4 algorithms: document
515 *) Add the possibility to add extra information to the memory leak
516 detecting output, to form tracebacks, showing from where each
517 allocation was originated: CRYPTO_push_info("constant string") adds
518 the string plus current file name and line number to a per-thread
519 stack, CRYPTO_pop_info() does the obvious, CRYPTO_remove_all_info()
520 is like calling CYRPTO_pop_info() until the stack is empty.
521 Also updated memory leak detection code to be multi-thread-safe.
524 *) Add options -text and -noout to pkcs7 utility and delete the
525 encryption options which never did anything. Update docs.
528 *) Add options to some of the utilities to allow the pass phrase
529 to be included on either the command line (not recommended on
530 OSes like Unix) or read from the environment. Update the
531 manpages and fix a few bugs.
534 *) Add a few manpages for some of the openssl commands.
537 *) Fix the -revoke option in ca. It was freeing up memory twice,
538 leaking and not finding already revoked certificates.
541 *) Extensive changes to support certificate auxiliary information.
542 This involves the use of X509_CERT_AUX structure and X509_AUX
543 functions. An X509_AUX function such as PEM_read_X509_AUX()
544 can still read in a certificate file in the usual way but it
545 will also read in any additional "auxiliary information". By
546 doing things this way a fair degree of compatibility can be
547 retained: existing certificates can have this information added
548 using the new 'x509' options.
550 Current auxiliary information includes an "alias" and some trust
551 settings. The trust settings will ultimately be used in enhanced
552 certificate chain verification routines: currently a certificate
553 can only be trusted if it is self signed and then it is trusted
557 *) Fix assembler for Alpha (tested only on DEC OSF not Linux or *BSD).
558 The problem was that one of the replacement routines had not been working
559 since SSLeay releases. For now the offending routine has been replaced
560 with non-optimised assembler. Even so, this now gives around 95%
561 performance improvement for 1024 bit RSA signs.
564 *) Hack to fix PKCS#7 decryption when used with some unorthodox RC2
565 handling. Most clients have the effective key size in bits equal to
566 the key length in bits: so a 40 bit RC2 key uses a 40 bit (5 byte) key.
567 A few however don't do this and instead use the size of the decrypted key
568 to determine the RC2 key length and the AlgorithmIdentifier to determine
569 the effective key length. In this case the effective key length can still
570 be 40 bits but the key length can be 168 bits for example. This is fixed
571 by manually forcing an RC2 key into the EVP_PKEY structure because the
572 EVP code can't currently handle unusual RC2 key sizes: it always assumes
573 the key length and effective key length are equal.
576 *) Add a bunch of functions that should simplify the creation of
577 X509_NAME structures. Now you should be able to do:
578 X509_NAME_add_entry_by_txt(nm, "CN", MBSTRING_ASC, "Steve", -1, -1, 0);
579 and have it automatically work out the correct field type and fill in
580 the structures. The more adventurous can try:
581 X509_NAME_add_entry_by_txt(nm, field, MBSTRING_UTF8, str, -1, -1, 0);
582 and it will (hopefully) work out the correct multibyte encoding.
585 *) Change the 'req' utility to use the new field handling and multibyte
586 copy routines. Before the DN field creation was handled in an ad hoc
587 way in req, ca, and x509 which was rather broken and didn't support
588 BMPStrings or UTF8Strings. Since some software doesn't implement
589 BMPStrings or UTF8Strings yet, they can be enabled using the config file
590 using the dirstring_type option. See the new comment in the default
591 openssl.cnf for more info.
594 *) Make crypto/rand/md_rand.c more robust:
595 - Assure unique random numbers after fork().
596 - Make sure that concurrent threads access the global counter and
597 md serializably so that we never lose entropy in them
598 or use exactly the same state in multiple threads.
599 Access to the large state is not always serializable because
600 the additional locking could be a performance killer, and
601 md should be large enough anyway.
604 *) New file apps/app_rand.c with commonly needed functionality
605 for handling the random seed file.
607 Use the random seed file in some applications that previously did not:
609 dsaparam -genkey (which also ignored its '-rand' option),
613 Except on systems with /dev/urandom, it is crucial to have a random
614 seed file at least for key creation, DSA signing, and for DH exchanges;
615 for RSA signatures we could do without one.
617 gendh and gendsa (unlike genrsa) used to read only the first byte
618 of each file listed in the '-rand' option. The function as previously
619 found in genrsa is now in app_rand.c and is used by all programs
620 that support '-rand'.
623 *) In RAND_write_file, use mode 0600 for creating files;
624 don't just chmod when it may be too late.
627 *) Report an error from X509_STORE_load_locations
628 when X509_LOOKUP_load_file or X509_LOOKUP_add_dir failed.
631 *) New function ASN1_mbstring_copy() this copies a string in either
632 ASCII, Unicode, Universal (4 bytes per character) or UTF8 format
633 into an ASN1_STRING type. A mask of permissible types is passed
634 and it chooses the "minimal" type to use or an error if not type
638 *) Add function equivalents to the various macros in asn1.h. The old
639 macros are retained with an M_ prefix. Code inside the library can
640 use the M_ macros. External code (including the openssl utility)
641 should *NOT* in order to be "shared library friendly".
644 *) Add various functions that can check a certificate's extensions
645 to see if it usable for various purposes such as SSL client,
646 server or S/MIME and CAs of these types. This is currently
647 VERY EXPERIMENTAL but will ultimately be used for certificate chain
648 verification. Also added a -purpose flag to x509 utility to
649 print out all the purposes.
652 *) Add a CRYPTO_EX_DATA to X509 certificate structure and associated
656 *) New X509V3_{X509,CRL,REVOKED}_get_d2i() functions. These will search
657 for, obtain and decode and extension and obtain its critical flag.
658 This allows all the necessary extension code to be handled in a
659 single function call.
662 *) RC4 tune-up featuring 30-40% performance improvement on most RISC
663 platforms. See crypto/rc4/rc4_enc.c for further details.
666 *) New -noout option to asn1parse. This causes no output to be produced
667 its main use is when combined with -strparse and -out to extract data
668 from a file (which may not be in ASN.1 format).
671 *) Fix for pkcs12 program. It was hashing an invalid certificate pointer
672 when producing the local key id.
673 [Richard Levitte <levitte@stacken.kth.se>]
675 *) New option -dhparam in s_server. This allows a DH parameter file to be
676 stated explicitly. If it is not stated then it tries the first server
677 certificate file. The previous behaviour hard coded the filename
681 *) Add -pubin and -pubout options to the rsa and dsa commands. These allow
682 a public key to be input or output. For example:
683 openssl rsa -in key.pem -pubout -out pubkey.pem
684 Also added necessary DSA public key functions to handle this.
687 *) Fix so PKCS7_dataVerify() doesn't crash if no certificates are contained
688 in the message. This was handled by allowing
689 X509_find_by_issuer_and_serial() to tolerate a NULL passed to it.
690 [Steve Henson, reported by Sampo Kellomaki <sampo@mail.neuronio.pt>]
692 *) Fix for bug in d2i_ASN1_bytes(): other ASN1 functions add an extra null
693 to the end of the strings whereas this didn't. This would cause problems
694 if strings read with d2i_ASN1_bytes() were later modified.
695 [Steve Henson, reported by Arne Ansper <arne@ats.cyber.ee>]
697 *) Fix for base64 decode bug. When a base64 bio reads only one line of
698 data and it contains EOF it will end up returning an error. This is
699 caused by input 46 bytes long. The cause is due to the way base64
700 BIOs find the start of base64 encoded data. They do this by trying a
701 trial decode on each line until they find one that works. When they
702 do a flag is set and it starts again knowing it can pass all the
703 data directly through the decoder. Unfortunately it doesn't reset
704 the context it uses. This means that if EOF is reached an attempt
705 is made to pass two EOFs through the context and this causes the
706 resulting error. This can also cause other problems as well. As is
707 usual with these problems it takes *ages* to find and the fix is
708 trivial: move one line.
709 [Steve Henson, reported by ian@uns.ns.ac.yu (Ivan Nejgebauer) ]
711 *) Ugly workaround to get s_client and s_server working under Windows. The
712 old code wouldn't work because it needed to select() on sockets and the
713 tty (for keypresses and to see if data could be written). Win32 only
714 supports select() on sockets so we select() with a 1s timeout on the
715 sockets and then see if any characters are waiting to be read, if none
716 are present then we retry, we also assume we can always write data to
717 the tty. This isn't nice because the code then blocks until we've
718 received a complete line of data and it is effectively polling the
719 keyboard at 1s intervals: however it's quite a bit better than not
720 working at all :-) A dedicated Windows application might handle this
721 with an event loop for example.
724 *) Enhance RSA_METHOD structure. Now there are two extra methods, rsa_sign
725 and rsa_verify. When the RSA_FLAGS_SIGN_VER option is set these functions
726 will be called when RSA_sign() and RSA_verify() are used. This is useful
727 if rsa_pub_dec() and rsa_priv_enc() equivalents are not available.
728 For this to work properly RSA_public_decrypt() and RSA_private_encrypt()
729 should *not* be used: RSA_sign() and RSA_verify() must be used instead.
730 This necessitated the support of an extra signature type NID_md5_sha1
731 for SSL signatures and modifications to the SSL library to use it instead
732 of calling RSA_public_decrypt() and RSA_private_encrypt().
735 *) Add new -verify -CAfile and -CApath options to the crl program, these
736 will lookup a CRL issuers certificate and verify the signature in a
737 similar way to the verify program. Tidy up the crl program so it
738 no longer accesses structures directly. Make the ASN1 CRL parsing a bit
739 less strict. It will now permit CRL extensions even if it is not
740 a V2 CRL: this will allow it to tolerate some broken CRLs.
743 *) Initialize all non-automatic variables each time one of the openssl
744 sub-programs is started (this is necessary as they may be started
745 multiple times from the "OpenSSL>" prompt).
746 [Lennart Bang, Bodo Moeller]
748 *) Preliminary compilation option RSA_NULL which disables RSA crypto without
749 removing all other RSA functionality (this is what NO_RSA does). This
750 is so (for example) those in the US can disable those operations covered
751 by the RSA patent while allowing storage and parsing of RSA keys and RSA
755 *) Non-copying interface to BIO pairs.
756 (still largely untested)
759 *) New function ANS1_tag2str() to convert an ASN1 tag to a descriptive
760 ASCII string. This was handled independently in various places before.
763 *) New functions UTF8_getc() and UTF8_putc() that parse and generate
764 UTF8 strings a character at a time.
767 *) Use client_version from client hello to select the protocol
768 (s23_srvr.c) and for RSA client key exchange verification
769 (s3_srvr.c), as required by the SSL 3.0/TLS 1.0 specifications.
772 *) Add various utility functions to handle SPKACs, these were previously
773 handled by poking round in the structure internals. Added new function
774 NETSCAPE_SPKI_print() to print out SPKAC and a new utility 'spkac' to
775 print, verify and generate SPKACs. Based on an original idea from
776 Massimiliano Pala <madwolf@comune.modena.it> but extensively modified.
779 *) RIPEMD160 is operational on all platforms and is back in 'make test'.
782 *) Allow the config file extension section to be overwritten on the
783 command line. Based on an original idea from Massimiliano Pala
784 <madwolf@comune.modena.it>. The new option is called -extensions
785 and can be applied to ca, req and x509. Also -reqexts to override
786 the request extensions in req and -crlexts to override the crl extensions
790 *) Add new feature to the SPKAC handling in ca. Now you can include
791 the same field multiple times by preceding it by "XXXX." for example:
794 this is the same syntax as used in the req config file.
797 *) Allow certificate extensions to be added to certificate requests. These
798 are specified in a 'req_extensions' option of the req section of the
799 config file. They can be printed out with the -text option to req but
800 are otherwise ignored at present.
803 *) Fix a horrible bug in enc_read() in crypto/evp/bio_enc.c: if the first
804 data read consists of only the final block it would not decrypted because
805 EVP_CipherUpdate() would correctly report zero bytes had been decrypted.
806 A misplaced 'break' also meant the decrypted final block might not be
807 copied until the next read.
810 *) Initial support for DH_METHOD. Again based on RSA_METHOD. Also added
811 a few extra parameters to the DH structure: these will be useful if
812 for example we want the value of 'q' or implement X9.42 DH.
815 *) Initial support for DSA_METHOD. This is based on the RSA_METHOD and
816 provides hooks that allow the default DSA functions or functions on a
817 "per key" basis to be replaced. This allows hardware acceleration and
818 hardware key storage to be handled without major modification to the
819 library. Also added low level modexp hooks and CRYPTO_EX structure and
820 associated functions.
823 *) Add a new flag to memory BIOs, BIO_FLAG_MEM_RDONLY. This marks the BIO
824 as "read only": it can't be written to and the buffer it points to will
825 not be freed. Reading from a read only BIO is much more efficient than
826 a normal memory BIO. This was added because there are several times when
827 an area of memory needs to be read from a BIO. The previous method was
828 to create a memory BIO and write the data to it, this results in two
829 copies of the data and an O(n^2) reading algorithm. There is a new
830 function BIO_new_mem_buf() which creates a read only memory BIO from
831 an area of memory. Also modified the PKCS#7 routines to use read only
835 *) Bugfix: ssl23_get_client_hello did not work properly when called in
836 state SSL23_ST_SR_CLNT_HELLO_B, i.e. when the first 7 bytes of
837 a SSLv2-compatible client hello for SSLv3 or TLSv1 could be read,
838 but a retry condition occured while trying to read the rest.
841 *) The PKCS7_ENC_CONTENT_new() function was setting the content type as
842 NID_pkcs7_encrypted by default: this was wrong since this should almost
843 always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle
844 the encrypted data type: this is a more sensible place to put it and it
845 allows the PKCS#12 code to be tidied up that duplicated this
849 *) Changed obj_dat.pl script so it takes its input and output files on
850 the command line. This should avoid shell escape redirection problems
854 *) Initial support for certificate extension requests, these are included
855 in things like Xenroll certificate requests. Included functions to allow
856 extensions to be obtained and added.
859 *) -crlf option to s_client and s_server for sending newlines as
860 CRLF (as required by many protocols).
863 Changes between 0.9.3a and 0.9.4 [09 Aug 1999]
865 *) Install libRSAglue.a when OpenSSL is built with RSAref.
866 [Ralf S. Engelschall]
868 *) A few more ``#ifndef NO_FP_API / #endif'' pairs for consistency.
869 [Andrija Antonijevic <TheAntony2@bigfoot.com>]
871 *) Fix -startdate and -enddate (which was missing) arguments to 'ca'
875 *) New function DSA_dup_DH, which duplicates DSA parameters/keys as
876 DH parameters/keys (q is lost during that conversion, but the resulting
877 DH parameters contain its length).
879 For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is
880 much faster than DH_generate_parameters (which creates parameters
881 where p = 2*q + 1), and also the smaller q makes DH computations
882 much more efficient (160-bit exponentiation instead of 1024-bit
883 exponentiation); so this provides a convenient way to support DHE
884 ciphersuites in SSL/TLS servers (see ssl/ssltest.c). It is of
885 utter importance to use
886 SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
888 SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
889 when such DH parameters are used, because otherwise small subgroup
890 attacks may become possible!
893 *) Avoid memory leak in i2d_DHparams.
896 *) Allow the -k option to be used more than once in the enc program:
897 this allows the same encrypted message to be read by multiple recipients.
900 *) New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts
901 an ASN1_OBJECT to a text string. If the "no_name" parameter is set then
902 it will always use the numerical form of the OID, even if it has a short
906 *) Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp
907 method only got called if p,q,dmp1,dmq1,iqmp components were present,
908 otherwise bn_mod_exp was called. In the case of hardware keys for example
909 no private key components need be present and it might store extra data
910 in the RSA structure, which cannot be accessed from bn_mod_exp.
911 By setting RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for
912 private key operations.
915 *) Added support for SPARC Linux.
918 *) pem_password_cb function type incompatibly changed from
919 typedef int pem_password_cb(char *buf, int size, int rwflag);
921 ....(char *buf, int size, int rwflag, void *userdata);
922 so that applications can pass data to their callbacks:
923 The PEM[_ASN1]_{read,write}... functions and macros now take an
924 additional void * argument, which is just handed through whenever
925 the password callback is called.
926 [Damien Miller <dmiller@ilogic.com.au>; tiny changes by Bodo Moeller]
928 New function SSL_CTX_set_default_passwd_cb_userdata.
930 Compatibility note: As many C implementations push function arguments
931 onto the stack in reverse order, the new library version is likely to
932 interoperate with programs that have been compiled with the old
933 pem_password_cb definition (PEM_whatever takes some data that
934 happens to be on the stack as its last argument, and the callback
935 just ignores this garbage); but there is no guarantee whatsoever that
938 *) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=...
939 (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused
940 problems not only on Windows, but also on some Unix platforms.
941 To avoid problematic command lines, these definitions are now in an
942 auto-generated file crypto/buildinf.h (created by crypto/Makefile.ssl
943 for standard "make" builds, by util/mk1mf.pl for "mk1mf" builds).
946 *) MIPS III/IV assembler module is reimplemented.
949 *) More DES library cleanups: remove references to srand/rand and
950 delete an unused file.
953 *) Add support for the the free Netwide assembler (NASM) under Win32,
954 since not many people have MASM (ml) and it can be hard to obtain.
955 This is currently experimental but it seems to work OK and pass all
956 the tests. Check out INSTALL.W32 for info.
959 *) Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections
960 without temporary keys kept an extra copy of the server key,
961 and connections with temporary keys did not free everything in case
965 *) New function RSA_check_key and new openssl rsa option -check
966 for verifying the consistency of RSA keys.
967 [Ulf Moeller, Bodo Moeller]
969 *) Various changes to make Win32 compile work:
970 1. Casts to avoid "loss of data" warnings in p5_crpt2.c
971 2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned
972 comparison" warnings.
973 3. Add sk_<TYPE>_sort to DEF file generator and do make update.
976 *) Add a debugging option to PKCS#5 v2 key generation function: when
977 you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and
978 derived keys are printed to stderr.
981 *) Copy the flags in ASN1_STRING_dup().
982 [Roman E. Pavlov <pre@mo.msk.ru>]
984 *) The x509 application mishandled signing requests containing DSA
985 keys when the signing key was also DSA and the parameters didn't match.
987 It was supposed to omit the parameters when they matched the signing key:
988 the verifying software was then supposed to automatically use the CA's
989 parameters if they were absent from the end user certificate.
991 Omitting parameters is no longer recommended. The test was also
992 the wrong way round! This was probably due to unusual behaviour in
993 EVP_cmp_parameters() which returns 1 if the parameters match.
994 This meant that parameters were omitted when they *didn't* match and
995 the certificate was useless. Certificates signed with 'ca' didn't have
997 [Steve Henson, reported by Doug Erickson <Doug.Erickson@Part.NET>]
999 *) Memory leak checking (-DCRYPTO_MDEBUG) had some problems.
1000 The interface is as follows:
1001 Applications can use
1002 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(),
1003 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop();
1004 "off" is now the default.
1005 The library internally uses
1006 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(),
1007 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on()
1008 to disable memory-checking temporarily.
1010 Some inconsistent states that previously were possible (and were
1011 even the default) are now avoided.
1013 -DCRYPTO_MDEBUG_TIME is new and additionally stores the current time
1014 with each memory chunk allocated; this is occasionally more helpful
1015 than just having a counter.
1017 -DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID.
1019 -DCRYPTO_MDEBUG_ALL enables all of the above, plus any future
1023 *) Introduce "mode" for SSL structures (with defaults in SSL_CTX),
1024 which largely parallels "options", but is for changing API behaviour,
1025 whereas "options" are about protocol behaviour.
1026 Initial "mode" flags are:
1028 SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when
1029 a single record has been written.
1030 SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write
1031 retries use the same buffer location.
1032 (But all of the contents must be
1036 *) Bugfix: SSL_set_mode ignored its parameter, only SSL_CTX_set_mode
1039 *) Fix problems with no-hmac etc.
1040 [Ulf Möller, pointed out by Brian Wellington <bwelling@tislabs.com>]
1042 *) New functions RSA_get_default_method(), RSA_set_method() and
1043 RSA_get_method(). These allows replacement of RSA_METHODs without having
1044 to mess around with the internals of an RSA structure.
1047 *) Fix memory leaks in DSA_do_sign and DSA_is_prime.
1048 Also really enable memory leak checks in openssl.c and in some
1050 [Chad C. Mulligan, Bodo Moeller]
1052 *) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess
1053 up the length of negative integers. This has now been simplified to just
1054 store the length when it is first determined and use it later, rather
1055 than trying to keep track of where data is copied and updating it to
1057 [Steve Henson, reported by Brien Wheeler
1058 <bwheeler@authentica-security.com>]
1060 *) Add a new function PKCS7_signatureVerify. This allows the verification
1061 of a PKCS#7 signature but with the signing certificate passed to the
1062 function itself. This contrasts with PKCS7_dataVerify which assumes the
1063 certificate is present in the PKCS#7 structure. This isn't always the
1064 case: certificates can be omitted from a PKCS#7 structure and be
1065 distributed by "out of band" means (such as a certificate database).
1068 *) Complete the PEM_* macros with DECLARE_PEM versions to replace the
1069 function prototypes in pem.h, also change util/mkdef.pl to add the
1070 necessary function names.
1073 *) mk1mf.pl (used by Windows builds) did not properly read the
1074 options set by Configure in the top level Makefile, and Configure
1075 was not even able to write more than one option correctly.
1076 Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended.
1079 *) New functions CONF_load_bio() and CONF_load_fp() to allow a config
1080 file to be loaded from a BIO or FILE pointer. The BIO version will
1081 for example allow memory BIOs to contain config info.
1084 *) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS.
1085 Whoever hopes to achieve shared-library compatibility across versions
1086 must use this, not the compile-time macro.
1087 (Exercise 0.9.4: Which is the minimum library version required by
1089 Note: All this applies only to multi-threaded programs, others don't
1093 *) Add missing case to s3_clnt.c state machine -- one of the new SSL tests
1094 through a BIO pair triggered the default case, i.e.
1095 SSLerr(...,SSL_R_UNKNOWN_STATE).
1098 *) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications
1099 can use the SSL library even if none of the specific BIOs is
1103 *) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value
1104 for the encoded length.
1105 [Jeon KyoungHo <khjeon@sds.samsung.co.kr>]
1107 *) Add initial documentation of the X509V3 functions.
1110 *) Add a new pair of functions PEM_write_PKCS8PrivateKey() and
1111 PEM_write_bio_PKCS8PrivateKey() that are equivalent to
1112 PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more
1113 secure PKCS#8 private key format with a high iteration count.
1116 *) Fix determination of Perl interpreter: A perl or perl5
1117 _directory_ in $PATH was also accepted as the interpreter.
1118 [Ralf S. Engelschall]
1120 *) Fix demos/sign/sign.c: well there wasn't anything strictly speaking
1121 wrong with it but it was very old and did things like calling
1122 PEM_ASN1_read() directly and used MD5 for the hash not to mention some
1126 *) Fix demos/selfsign.c: it used obsolete and deleted functions, changed
1127 to use the new extension code.
1130 *) Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c
1131 with macros. This should make it easier to change their form, add extra
1132 arguments etc. Fix a few PEM prototypes which didn't have cipher as a
1136 *) Add to configuration table a new entry that can specify an alternative
1137 name for unistd.h (for pre-POSIX systems); we need this for NeXTstep,
1138 according to Mark Crispin <MRC@Panda.COM>.
1142 *) DES CBC did not update the IV. Weird.
1145 des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does.
1146 Changing the behaviour of the former might break existing programs --
1147 where IV updating is needed, des_ncbc_encrypt can be used.
1150 *) When bntest is run from "make test" it drives bc to check its
1151 calculations, as well as internally checking them. If an internal check
1152 fails, it needs to cause bc to give a non-zero result or make test carries
1153 on without noticing the failure. Fixed.
1156 *) DES library cleanups.
1159 *) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be
1160 used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit
1161 ciphers. NOTE: although the key derivation function has been verified
1162 against some published test vectors it has not been extensively tested
1163 yet. Added a -v2 "cipher" option to pkcs8 application to allow the use
1167 *) Instead of "mkdir -p", which is not fully portable, use new
1168 Perl script "util/mkdir-p.pl".
1171 *) Rewrite the way password based encryption (PBE) is handled. It used to
1172 assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter
1173 structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms
1174 but doesn't apply to PKCS#5 v2.0 where it can be something else. Now
1175 the 'parameter' field of the AlgorithmIdentifier is passed to the
1176 underlying key generation function so it must do its own ASN1 parsing.
1177 This has also changed the EVP_PBE_CipherInit() function which now has a
1178 'parameter' argument instead of literal salt and iteration count values
1179 and the function EVP_PBE_ALGOR_CipherInit() has been deleted.
1182 *) Support for PKCS#5 v1.5 compatible password based encryption algorithms
1183 and PKCS#8 functionality. New 'pkcs8' application linked to openssl.
1184 Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE
1185 KEY" because this clashed with PKCS#8 unencrypted string. Since this
1186 value was just used as a "magic string" and not used directly its
1187 value doesn't matter.
1190 *) Introduce some semblance of const correctness to BN. Shame C doesn't
1194 *) "linux-sparc64" configuration (ultrapenguin).
1195 [Ray Miller <ray.miller@oucs.ox.ac.uk>]
1196 "linux-sparc" configuration.
1197 [Christian Forster <fo@hawo.stw.uni-erlangen.de>]
1199 *) config now generates no-xxx options for missing ciphers.
1202 *) Support the EBCDIC character set (work in progress).
1203 File ebcdic.c not yet included because it has a different license.
1204 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
1206 *) Support BS2000/OSD-POSIX.
1207 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
1209 *) Make callbacks for key generation use void * instead of char *.
1212 *) Make S/MIME samples compile (not yet tested).
1215 *) Additional typesafe stacks.
1218 *) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x).
1222 Changes between 0.9.3 and 0.9.3a [29 May 1999]
1224 *) New configuration variant "sco5-gcc".
1226 *) Updated some demos.
1227 [Sean O Riordain, Wade Scholine]
1229 *) Add missing BIO_free at exit of pkcs12 application.
1232 *) Fix memory leak in conf.c.
1235 *) Updates for Win32 to assembler version of MD5.
1238 *) Set #! path to perl in apps/der_chop to where we found it
1239 instead of using a fixed path.
1242 *) SHA library changes for irix64-mips4-cc.
1245 *) Improvements for VMS support.
1249 Changes between 0.9.2b and 0.9.3 [24 May 1999]
1251 *) Bignum library bug fix. IRIX 6 passes "make test" now!
1252 This also avoids the problems with SC4.2 and unpatched SC5.
1253 [Andy Polyakov <appro@fy.chalmers.se>]
1255 *) New functions sk_num, sk_value and sk_set to replace the previous macros.
1256 These are required because of the typesafe stack would otherwise break
1257 existing code. If old code used a structure member which used to be STACK
1258 and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with
1259 sk_num or sk_value it would produce an error because the num, data members
1260 are not present in STACK_OF. Now it just produces a warning. sk_set
1261 replaces the old method of assigning a value to sk_value
1262 (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code
1263 that does this will no longer work (and should use sk_set instead) but
1264 this could be regarded as a "questionable" behaviour anyway.
1267 *) Fix most of the other PKCS#7 bugs. The "experimental" code can now
1268 correctly handle encrypted S/MIME data.
1271 *) Change type of various DES function arguments from des_cblock
1272 (which means, in function argument declarations, pointer to char)
1273 to des_cblock * (meaning pointer to array with 8 char elements),
1274 which allows the compiler to do more typechecking; it was like
1275 that back in SSLeay, but with lots of ugly casts.
1277 Introduce new type const_des_cblock.
1280 *) Reorganise the PKCS#7 library and get rid of some of the more obvious
1281 problems: find RecipientInfo structure that matches recipient certificate
1282 and initialise the ASN1 structures properly based on passed cipher.
1285 *) Belatedly make the BN tests actually check the results.
1288 *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion
1289 to and from BNs: it was completely broken. New compilation option
1290 NEG_PUBKEY_BUG to allow for some broken certificates that encode public
1291 key elements as negative integers.
1294 *) Reorganize and speed up MD5.
1295 [Andy Polyakov <appro@fy.chalmers.se>]
1298 [Richard Levitte <richard@levitte.org>]
1300 *) New option -out to asn1parse to allow the parsed structure to be
1301 output to a file. This is most useful when combined with the -strparse
1302 option to examine the output of things like OCTET STRINGS.
1305 *) Make SSL library a little more fool-proof by not requiring any longer
1306 that SSL_set_{accept,connect}_state be called before
1307 SSL_{accept,connect} may be used (SSL_set_..._state is omitted
1308 in many applications because usually everything *appeared* to work as
1309 intended anyway -- now it really works as intended).
1312 *) Move openssl.cnf out of lib/.
1315 *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall
1316 -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
1317 -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+
1318 [Ralf S. Engelschall]
1320 *) Various fixes to the EVP and PKCS#7 code. It may now be able to
1321 handle PKCS#7 enveloped data properly.
1322 [Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve]
1324 *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
1325 copying pointers. The cert_st handling is changed by this in
1326 various ways (and thus what used to be known as ctx->default_cert
1327 is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
1328 any longer when s->cert does not give us what we need).
1329 ssl_cert_instantiate becomes obsolete by this change.
1330 As soon as we've got the new code right (possibly it already is?),
1331 we have solved a couple of bugs of the earlier code where s->cert
1332 was used as if it could not have been shared with other SSL structures.
1334 Note that using the SSL API in certain dirty ways now will result
1335 in different behaviour than observed with earlier library versions:
1336 Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
1337 does not influence s as it used to.
1339 In order to clean up things more thoroughly, inside SSL_SESSION
1340 we don't use CERT any longer, but a new structure SESS_CERT
1341 that holds per-session data (if available); currently, this is
1342 the peer's certificate chain and, for clients, the server's certificate
1343 and temporary key. CERT holds only those values that can have
1344 meaningful defaults in an SSL_CTX.
1347 *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure
1348 from the internal representation. Various PKCS#7 fixes: remove some
1349 evil casts and set the enc_dig_alg field properly based on the signing
1353 *) Allow PKCS#12 password to be set from the command line or the
1354 environment. Let 'ca' get its config file name from the environment
1355 variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req'
1359 *) Allow certificate policies extension to use an IA5STRING for the
1360 organization field. This is contrary to the PKIX definition but
1361 VeriSign uses it and IE5 only recognises this form. Document 'x509'
1365 *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic,
1366 without disallowing inline assembler and the like for non-pedantic builds.
1369 *) Support Borland C++ builder.
1370 [Janez Jere <jj@void.si>, modified by Ulf Möller]
1375 *) SHA-1 cleanups and performance enhancements.
1376 [Andy Polyakov <appro@fy.chalmers.se>]
1378 *) Sparc v8plus assembler for the bignum library.
1379 [Andy Polyakov <appro@fy.chalmers.se>]
1381 *) Accept any -xxx and +xxx compiler options in Configure.
1384 *) Update HPUX configuration.
1387 *) Add missing sk_<type>_unshift() function to safestack.h
1388 [Ralf S. Engelschall]
1390 *) New function SSL_CTX_use_certificate_chain_file that sets the
1391 "extra_cert"s in addition to the certificate. (This makes sense
1392 only for "PEM" format files, as chains as a whole are not
1396 *) Support verify_depth from the SSL API.
1397 x509_vfy.c had what can be considered an off-by-one-error:
1398 Its depth (which was not part of the external interface)
1399 was actually counting the number of certificates in a chain;
1400 now it really counts the depth.
1403 *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used
1404 instead of X509err, which often resulted in confusing error
1405 messages since the error codes are not globally unique
1406 (e.g. an alleged error in ssl3_accept when a certificate
1407 didn't match the private key).
1409 *) New function SSL_CTX_set_session_id_context that allows to set a default
1410 value (so that you don't need SSL_set_session_id_context for each
1411 connection using the SSL_CTX).
1414 *) OAEP decoding bug fix.
1417 *) Support INSTALL_PREFIX for package builders, as proposed by
1421 *) New Configure options "threads" and "no-threads". For systems
1422 where the proper compiler options are known (currently Solaris
1423 and Linux), "threads" is the default.
1426 *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
1429 *) Install various scripts to $(OPENSSLDIR)/misc, not to
1430 $(INSTALLTOP)/bin -- they shouldn't clutter directories
1431 such as /usr/local/bin.
1434 *) "make linux-shared" to build shared libraries.
1435 [Niels Poppe <niels@netbox.org>]
1437 *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
1440 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
1441 extension adding in x509 utility.
1444 *) Remove NOPROTO sections and error code comments.
1447 *) Partial rewrite of the DEF file generator to now parse the ANSI
1451 *) New Configure options --prefix=DIR and --openssldir=DIR.
1454 *) Complete rewrite of the error code script(s). It is all now handled
1455 by one script at the top level which handles error code gathering,
1456 header rewriting and C source file generation. It should be much better
1457 than the old method: it now uses a modified version of Ulf's parser to
1458 read the ANSI prototypes in all header files (thus the old K&R definitions
1459 aren't needed for error creation any more) and do a better job of
1460 translating function codes into names. The old 'ASN1 error code imbedded
1461 in a comment' is no longer necessary and it doesn't use .err files which
1462 have now been deleted. Also the error code call doesn't have to appear all
1463 on one line (which resulted in some large lines...).
1466 *) Change #include filenames from <foo.h> to <openssl/foo.h>.
1469 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
1470 0 (which usually indicates a closed connection), but continue reading.
1473 *) Fix some race conditions.
1476 *) Add support for CRL distribution points extension. Add Certificate
1477 Policies and CRL distribution points documentation.
1480 *) Move the autogenerated header file parts to crypto/opensslconf.h.
1483 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
1484 8 of keying material. Merlin has also confirmed interop with this fix
1485 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
1486 [Merlin Hughes <merlin@baltimore.ie>]
1488 *) Fix lots of warnings.
1489 [Richard Levitte <levitte@stacken.kth.se>]
1491 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
1492 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
1493 [Richard Levitte <levitte@stacken.kth.se>]
1495 *) Fix problems with sizeof(long) == 8.
1496 [Andy Polyakov <appro@fy.chalmers.se>]
1498 *) Change functions to ANSI C.
1501 *) Fix typos in error codes.
1502 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
1504 *) Remove defunct assembler files from Configure.
1507 *) SPARC v8 assembler BIGNUM implementation.
1508 [Andy Polyakov <appro@fy.chalmers.se>]
1510 *) Support for Certificate Policies extension: both print and set.
1511 Various additions to support the r2i method this uses.
1514 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
1515 return a const string when you are expecting an allocated buffer.
1518 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
1519 types DirectoryString and DisplayText.
1522 *) Add code to allow r2i extensions to access the configuration database,
1523 add an LHASH database driver and add several ctx helper functions.
1526 *) Fix an evil bug in bn_expand2() which caused various BN functions to
1527 fail when they extended the size of a BIGNUM.
1530 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
1531 support typesafe stack.
1534 *) Fix typo in SSL_[gs]et_options().
1535 [Nils Frostberg <nils@medcom.se>]
1537 *) Delete various functions and files that belonged to the (now obsolete)
1538 old X509V3 handling code.
1541 *) New Configure option "rsaref".
1544 *) Don't auto-generate pem.h.
1547 *) Introduce type-safe ASN.1 SETs.
1550 *) Convert various additional casted stacks to type-safe STACK_OF() variants.
1551 [Ben Laurie, Ralf S. Engelschall, Steve Henson]
1553 *) Introduce type-safe STACKs. This will almost certainly break lots of code
1554 that links with OpenSSL (well at least cause lots of warnings), but fear
1555 not: the conversion is trivial, and it eliminates loads of evil casts. A
1556 few STACKed things have been converted already. Feel free to convert more.
1557 In the fullness of time, I'll do away with the STACK type altogether.
1560 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
1561 specified in <certfile> by updating the entry in the index.txt file.
1562 This way one no longer has to edit the index.txt file manually for
1563 revoking a certificate. The -revoke option does the gory details now.
1564 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
1566 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
1567 `-text' option at all and this way the `-noout -text' combination was
1568 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
1569 [Ralf S. Engelschall]
1571 *) Make sure a corresponding plain text error message exists for the
1572 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
1573 verify callback function determined that a certificate was revoked.
1574 [Ralf S. Engelschall]
1576 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
1577 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
1578 all available cipers including rc5, which was forgotten until now.
1579 In order to let the testing shell script know which algorithms
1580 are available, a new (up to now undocumented) command
1581 "openssl list-cipher-commands" is used.
1584 *) Bugfix: s_client occasionally would sleep in select() when
1585 it should have checked SSL_pending() first.
1588 *) New functions DSA_do_sign and DSA_do_verify to provide access to
1589 the raw DSA values prior to ASN.1 encoding.
1592 *) Tweaks to Configure
1593 [Niels Poppe <niels@netbox.org>]
1595 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
1599 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
1602 *) New config option to avoid instructions that are illegal on the 80386.
1603 The default code is faster, but requires at least a 486.
1606 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
1607 SSL2_SERVER_VERSION (not used at all) macros, which are now the
1608 same as SSL2_VERSION anyway.
1611 *) New "-showcerts" option for s_client.
1614 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
1615 application. Various cleanups and fixes.
1618 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
1619 modify error routines to work internally. Add error codes and PBE init
1620 to library startup routines.
1623 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
1624 packing functions to asn1 and evp. Changed function names and error
1625 codes along the way.
1628 *) PKCS12 integration: and so it begins... First of several patches to
1629 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
1630 objects to objects.h
1633 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
1634 and display support for Thawte strong extranet extension.
1637 *) Add LinuxPPC support.
1638 [Jeff Dubrule <igor@pobox.org>]
1640 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
1641 bn_div_words in alpha.s.
1642 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
1644 *) Make sure the RSA OAEP test is skipped under -DRSAref because
1645 OAEP isn't supported when OpenSSL is built with RSAref.
1646 [Ulf Moeller <ulf@fitug.de>]
1648 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
1649 so they no longer are missing under -DNOPROTO.
1650 [Soren S. Jorvang <soren@t.dk>]
1653 Changes between 0.9.1c and 0.9.2b [22 Mar 1999]
1655 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
1656 doesn't work when the session is reused. Coming soon!
1659 *) Fix a security hole, that allows sessions to be reused in the wrong
1660 context thus bypassing client cert protection! All software that uses
1661 client certs and session caches in multiple contexts NEEDS PATCHING to
1662 allow session reuse! A fuller solution is in the works.
1663 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
1665 *) Some more source tree cleanups (removed obsolete files
1666 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
1667 permission on "config" script to be executable) and a fix for the INSTALL
1669 [Ulf Moeller <ulf@fitug.de>]
1671 *) Remove some legacy and erroneous uses of malloc, free instead of
1673 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
1675 *) Make rsa_oaep_test return non-zero on error.
1676 [Ulf Moeller <ulf@fitug.de>]
1678 *) Add support for native Solaris shared libraries. Configure
1679 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
1680 if someone would make that last step automatic.
1681 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
1683 *) ctx_size was not built with the right compiler during "make links". Fixed.
1686 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
1687 except NULL ciphers". This means the default cipher list will no longer
1688 enable NULL ciphers. They need to be specifically enabled e.g. with
1689 the string "DEFAULT:eNULL".
1692 *) Fix to RSA private encryption routines: if p < q then it would
1693 occasionally produce an invalid result. This will only happen with
1694 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
1697 *) Be less restrictive and allow also `perl util/perlpath.pl
1698 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
1699 because this way one can also use an interpreter named `perl5' (which is
1700 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
1701 installed as `perl').
1702 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
1704 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
1705 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
1707 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
1708 advapi32.lib to Win32 build and change the pem test comparision
1709 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
1710 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
1711 and crypto/des/ede_cbcm_enc.c.
1714 *) DES quad checksum was broken on big-endian architectures. Fixed.
1717 *) Comment out two functions in bio.h that aren't implemented. Fix up the
1718 Win32 test batch file so it (might) work again. The Win32 test batch file
1719 is horrible: I feel ill....
1722 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
1723 in e_os.h. Audit of header files to check ANSI and non ANSI
1724 sections: 10 functions were absent from non ANSI section and not exported
1725 from Windows DLLs. Fixed up libeay.num for new functions.
1728 *) Make `openssl version' output lines consistent.
1729 [Ralf S. Engelschall]
1731 *) Fix Win32 symbol export lists for BIO functions: Added
1732 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
1733 to ms/libeay{16,32}.def.
1734 [Ralf S. Engelschall]
1736 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
1737 fine under Unix and passes some trivial tests I've now added. But the
1738 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
1739 added to make sure no one expects that this stuff really works in the
1740 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
1741 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
1743 [Ralf S. Engelschall]
1745 *) Fix the generation of two part addresses in perl.
1746 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
1748 *) Add config entry for Linux on MIPS.
1749 [John Tobey <jtobey@channel1.com>]
1751 *) Make links whenever Configure is run, unless we are on Windoze.
1754 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
1755 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
1759 *) Add a useful kludge to allow package maintainers to specify compiler and
1760 other platforms details on the command line without having to patch the
1761 Configure script everytime: One now can use ``perl Configure
1762 <id>:<details>'', i.e. platform ids are allowed to have details appended
1763 to them (seperated by colons). This is treated as there would be a static
1764 pre-configured entry in Configure's %table under key <id> with value
1765 <details> and ``perl Configure <id>'' is called. So, when you want to
1766 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
1767 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
1768 now, which overrides the FreeBSD-elf entry on-the-fly.
1769 [Ralf S. Engelschall]
1771 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
1774 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
1775 on the `perl Configure ...' command line. This way one can compile
1776 OpenSSL libraries with Position Independent Code (PIC) which is needed
1777 for linking it into DSOs.
1778 [Ralf S. Engelschall]
1780 *) Remarkably, export ciphers were totally broken and no-one had noticed!
1784 *) Cleaned up the LICENSE document: The official contact for any license
1785 questions now is the OpenSSL core team under openssl-core@openssl.org.
1786 And add a paragraph about the dual-license situation to make sure people
1787 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
1788 to the OpenSSL toolkit.
1789 [Ralf S. Engelschall]
1791 *) General source tree makefile cleanups: Made `making xxx in yyy...'
1792 display consistent in the source tree and replaced `/bin/rm' by `rm'.
1793 Additonally cleaned up the `make links' target: Remove unnecessary
1794 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
1795 to speed processing and no longer clutter the display with confusing
1796 stuff. Instead only the actually done links are displayed.
1797 [Ralf S. Engelschall]
1799 *) Permit null encryption ciphersuites, used for authentication only. It used
1800 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
1801 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
1805 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
1806 signed attributes when verifying signatures (this would break them),
1807 the detached data encoding was wrong and public keys obtained using
1808 X509_get_pubkey() weren't freed.
1811 *) Add text documentation for the BUFFER functions. Also added a work around
1812 to a Win95 console bug. This was triggered by the password read stuff: the
1813 last character typed gets carried over to the next fread(). If you were
1814 generating a new cert request using 'req' for example then the last
1815 character of the passphrase would be CR which would then enter the first
1819 *) Added the new `Includes OpenSSL Cryptography Software' button as
1820 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
1821 button and can be used by applications based on OpenSSL to show the
1822 relationship to the OpenSSL project.
1823 [Ralf S. Engelschall]
1825 *) Remove confusing variables in function signatures in files
1826 ssl/ssl_lib.c and ssl/ssl.h.
1827 [Lennart Bong <lob@kulthea.stacken.kth.se>]
1829 *) Don't install bss_file.c under PREFIX/include/
1830 [Lennart Bong <lob@kulthea.stacken.kth.se>]
1832 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
1833 functions that return function pointers and has support for NT specific
1834 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
1835 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
1836 unsigned to signed types: this was killing the Win32 compile.
1839 *) Add new certificate file to stack functions,
1840 SSL_add_dir_cert_subjects_to_stack() and
1841 SSL_add_file_cert_subjects_to_stack(). These largely supplant
1842 SSL_load_client_CA_file(), and can be used to add multiple certs easily
1843 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
1844 This means that Apache-SSL and similar packages don't have to mess around
1845 to add as many CAs as they want to the preferred list.
1848 *) Experiment with doxygen documentation. Currently only partially applied to
1850 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
1851 openssl.doxy as the configuration file.
1854 *) Get rid of remaining C++-style comments which strict C compilers hate.
1855 [Ralf S. Engelschall, pointed out by Carlos Amengual]
1857 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
1858 compiled in by default: it has problems with large keys.
1861 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
1862 DH private keys and/or callback functions which directly correspond to
1863 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
1864 is needed for applications which have to configure certificates on a
1865 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
1867 For the RSA certificate situation is makes no difference, but
1868 for the DSA certificate situation this fixes the "no shared cipher"
1869 problem where the OpenSSL cipher selection procedure failed because the
1870 temporary keys were not overtaken from the context and the API provided
1871 no way to reconfigure them.
1872 The new functions now let applications reconfigure the stuff and they
1873 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
1874 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
1875 non-public-API function ssl_cert_instantiate() is used as a helper
1876 function and also to reduce code redundancy inside ssl_rsa.c.
1877 [Ralf S. Engelschall]
1879 *) Move s_server -dcert and -dkey options out of the undocumented feature
1880 area because they are useful for the DSA situation and should be
1881 recognized by the users.
1882 [Ralf S. Engelschall]
1884 *) Fix the cipher decision scheme for export ciphers: the export bits are
1885 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
1886 SSL_EXP_MASK. So, the original variable has to be used instead of the
1887 already masked variable.
1888 [Richard Levitte <levitte@stacken.kth.se>]
1890 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
1891 [Richard Levitte <levitte@stacken.kth.se>]
1893 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
1894 from `int' to `unsigned int' because it's a length and initialized by
1895 EVP_DigestFinal() which expects an `unsigned int *'.
1896 [Richard Levitte <levitte@stacken.kth.se>]
1898 *) Don't hard-code path to Perl interpreter on shebang line of Configure
1899 script. Instead use the usual Shell->Perl transition trick.
1900 [Ralf S. Engelschall]
1902 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
1903 (in addition to RSA certificates) to match the behaviour of `openssl dsa
1904 -noout -modulus' as it's already the case for `openssl rsa -noout
1905 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
1906 currently the public key is printed (a decision which was already done by
1907 `openssl dsa -modulus' in the past) which serves a similar purpose.
1908 Additionally the NO_RSA no longer completely removes the whole -modulus
1909 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
1911 [Ralf S. Engelschall]
1913 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
1914 BIO. See the source (crypto/evp/bio_ok.c) for more info.
1915 [Arne Ansper <arne@ats.cyber.ee>]
1917 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
1918 to be added. Now both 'req' and 'ca' can use new objects defined in the
1922 *) Add cool BIO that does syslog (or event log on NT).
1923 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
1925 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
1926 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
1927 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
1928 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
1931 *) Add preliminary config info for new extension code.
1934 *) Make RSA_NO_PADDING really use no padding.
1935 [Ulf Moeller <ulf@fitug.de>]
1937 *) Generate errors when private/public key check is done.
1940 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
1941 for some CRL extensions and new objects added.
1944 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
1945 key usage extension and fuller support for authority key id.
1948 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
1949 padding method for RSA, which is recommended for new applications in PKCS
1950 #1 v2.0 (RFC 2437, October 1998).
1951 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
1952 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
1953 against Bleichbacher's attack on RSA.
1954 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
1957 *) Updates to the new SSL compression code
1958 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
1960 *) Fix so that the version number in the master secret, when passed
1961 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
1962 (because the server will not accept higher), that the version number
1963 is 0x03,0x01, not 0x03,0x00
1964 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
1966 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
1967 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
1968 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
1971 *) Support for RAW extensions where an arbitrary extension can be
1972 created by including its DER encoding. See apps/openssl.cnf for
1976 *) Make sure latest Perl versions don't interpret some generated C array
1977 code as Perl array code in the crypto/err/err_genc.pl script.
1978 [Lars Weber <3weber@informatik.uni-hamburg.de>]
1980 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
1981 not many people have the assembler. Various Win32 compilation fixes and
1982 update to the INSTALL.W32 file with (hopefully) more accurate Win32
1986 *) Modify configure script 'Configure' to automatically create crypto/date.h
1987 file under Win32 and also build pem.h from pem.org. New script
1988 util/mkfiles.pl to create the MINFO file on environments that can't do a
1989 'make files': perl util/mkfiles.pl >MINFO should work.
1992 *) Major rework of DES function declarations, in the pursuit of correctness
1993 and purity. As a result, many evil casts evaporated, and some weirdness,
1994 too. You may find this causes warnings in your code. Zapping your evil
1995 casts will probably fix them. Mostly.
1998 *) Fix for a typo in asn1.h. Bug fix to object creation script
1999 obj_dat.pl. It considered a zero in an object definition to mean
2000 "end of object": none of the objects in objects.h have any zeros
2001 so it wasn't spotted.
2002 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
2004 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
2005 Masking (CBCM). In the absence of test vectors, the best I have been able
2006 to do is check that the decrypt undoes the encrypt, so far. Send me test
2007 vectors if you have them.
2010 *) Correct calculation of key length for export ciphers (too much space was
2011 allocated for null ciphers). This has not been tested!
2014 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
2015 message is now correct (it understands "crypto" and "ssl" on its
2016 command line). There is also now an "update" option. This will update
2017 the util/ssleay.num and util/libeay.num files with any new functions.
2019 perl util/mkdef.pl crypto ssl update
2020 it will update them.
2023 *) Overhauled the Perl interface (perl/*):
2024 - ported BN stuff to OpenSSL's different BN library
2025 - made the perl/ source tree CVS-aware
2026 - renamed the package from SSLeay to OpenSSL (the files still contain
2027 their history because I've copied them in the repository)
2028 - removed obsolete files (the test scripts will be replaced
2029 by better Test::Harness variants in the future)
2030 [Ralf S. Engelschall]
2032 *) First cut for a very conservative source tree cleanup:
2033 1. merge various obsolete readme texts into doc/ssleay.txt
2034 where we collect the old documents and readme texts.
2035 2. remove the first part of files where I'm already sure that we no
2036 longer need them because of three reasons: either they are just temporary
2037 files which were left by Eric or they are preserved original files where
2038 I've verified that the diff is also available in the CVS via "cvs diff
2039 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
2040 the crypto/md/ stuff).
2041 [Ralf S. Engelschall]
2043 *) More extension code. Incomplete support for subject and issuer alt
2044 name, issuer and authority key id. Change the i2v function parameters
2045 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
2046 what that's for :-) Fix to ASN1 macro which messed up
2047 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
2050 *) Preliminary support for ENUMERATED type. This is largely copied from the
2054 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
2055 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
2057 *) Make sure `make rehash' target really finds the `openssl' program.
2058 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
2060 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
2061 like to hear about it if this slows down other processors.
2064 *) Add CygWin32 platform information to Configure script.
2065 [Alan Batie <batie@aahz.jf.intel.com>]
2067 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
2068 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
2070 *) New program nseq to manipulate netscape certificate sequences
2073 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
2077 *) Fixes to BN code. Previously the default was to define BN_RECURSION
2078 but the BN code had some problems that would cause failures when
2079 doing certificate verification and some other functions.
2080 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
2082 *) Add ASN1 and PEM code to support netscape certificate sequences.
2085 *) Add ASN1 and PEM code to support netscape certificate sequences.
2088 *) Add several PKIX and private extended key usage OIDs.
2091 *) Modify the 'ca' program to handle the new extension code. Modify
2092 openssl.cnf for new extension format, add comments.
2095 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
2096 and add a sample to openssl.cnf so req -x509 now adds appropriate
2100 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
2101 error code, add initial support to X509_print() and x509 application.
2104 *) Takes a deep breath and start addding X509 V3 extension support code. Add
2105 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
2106 stuff is currently isolated and isn't even compiled yet.
2109 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
2110 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
2111 Removed the versions check from X509 routines when loading extensions:
2112 this allows certain broken certificates that don't set the version
2113 properly to be processed.
2116 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
2117 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
2118 can still be regenerated with "make depend".
2121 *) Spelling mistake in C version of CAST-128.
2122 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
2124 *) Changes to the error generation code. The perl script err-code.pl
2125 now reads in the old error codes and retains the old numbers, only
2126 adding new ones if necessary. It also only changes the .err files if new
2127 codes are added. The makefiles have been modified to only insert errors
2128 when needed (to avoid needlessly modifying header files). This is done
2129 by only inserting errors if the .err file is newer than the auto generated
2130 C file. To rebuild all the error codes from scratch (the old behaviour)
2131 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
2132 or delete all the .err files.
2135 *) CAST-128 was incorrectly implemented for short keys. The C version has
2136 been fixed, but is untested. The assembler versions are also fixed, but
2137 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
2138 to regenerate it if needed.
2139 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
2140 Hagino <itojun@kame.net>]
2142 *) File was opened incorrectly in randfile.c.
2143 [Ulf Möller <ulf@fitug.de>]
2145 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
2146 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
2147 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
2148 al: it's just almost always a UTCTime. Note this patch adds new error
2149 codes so do a "make errors" if there are problems.
2152 *) Correct Linux 1 recognition in config.
2153 [Ulf Möller <ulf@fitug.de>]
2155 *) Remove pointless MD5 hash when using DSA keys in ca.
2156 [Anonymous <nobody@replay.com>]
2158 *) Generate an error if given an empty string as a cert directory. Also
2159 generate an error if handed NULL (previously returned 0 to indicate an
2160 error, but didn't set one).
2161 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
2163 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
2166 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
2167 parameters. This was causing a warning which killed off the Win32 compile.
2170 *) Remove C++ style comments from crypto/bn/bn_local.h.
2171 [Neil Costigan <neil.costigan@celocom.com>]
2173 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
2174 based on a text string, looking up short and long names and finally
2175 "dot" format. The "dot" format stuff didn't work. Added new function
2176 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
2177 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
2178 OID is not part of the table.
2181 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
2182 X509_LOOKUP_by_alias().
2185 *) Sort openssl functions by name.
2188 *) Get the gendsa program working (hopefully) and add it to app list. Remove
2189 encryption from sample DSA keys (in case anyone is interested the password
2193 *) Make _all_ *_free functions accept a NULL pointer.
2194 [Frans Heymans <fheymans@isaserver.be>]
2196 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
2198 [Anonymous <nobody@replay.com>]
2200 *) s_server should send the CAfile as acceptable CAs, not its own cert.
2201 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
2203 *) Don't blow it for numeric -newkey arguments to apps/req.
2204 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
2206 *) Temp key "for export" tests were wrong in s3_srvr.c.
2207 [Anonymous <nobody@replay.com>]
2209 *) Add prototype for temp key callback functions
2210 SSL_CTX_set_tmp_{rsa,dh}_callback().
2213 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
2214 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
2217 *) X509_name_add_entry() freed the wrong thing after an error.
2218 [Arne Ansper <arne@ats.cyber.ee>]
2220 *) rsa_eay.c would attempt to free a NULL context.
2221 [Arne Ansper <arne@ats.cyber.ee>]
2223 *) BIO_s_socket() had a broken should_retry() on Windoze.
2224 [Arne Ansper <arne@ats.cyber.ee>]
2226 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
2227 [Arne Ansper <arne@ats.cyber.ee>]
2229 *) Make sure the already existing X509_STORE->depth variable is initialized
2230 in X509_STORE_new(), but document the fact that this variable is still
2231 unused in the certificate verification process.
2232 [Ralf S. Engelschall]
2234 *) Fix the various library and apps files to free up pkeys obtained from
2235 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
2238 *) Fix reference counting in X509_PUBKEY_get(). This makes
2239 demos/maurice/example2.c work, amongst others, probably.
2240 [Steve Henson and Ben Laurie]
2242 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
2243 `openssl' and second, the shortcut symlinks for the `openssl <command>'
2244 are no longer created. This way we have a single and consistent command
2245 line interface `openssl <command>', similar to `cvs <command>'.
2246 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
2248 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
2249 BIT STRING wrapper always have zero unused bits.
2252 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
2255 *) Make the top-level INSTALL documentation easier to understand.
2258 *) Makefiles updated to exit if an error occurs in a sub-directory
2259 make (including if user presses ^C) [Paul Sutton]
2261 *) Make Montgomery context stuff explicit in RSA data structure.
2264 *) Fix build order of pem and err to allow for generated pem.h.
2267 *) Fix renumbering bug in X509_NAME_delete_entry().
2270 *) Enhanced the err-ins.pl script so it makes the error library number
2271 global and can add a library name. This is needed for external ASN1 and
2272 other error libraries.
2275 *) Fixed sk_insert which never worked properly.
2278 *) Fix ASN1 macros so they can handle indefinite length construted
2279 EXPLICIT tags. Some non standard certificates use these: they can now
2283 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
2284 into a single doc/ssleay.txt bundle. This way the information is still
2285 preserved but no longer messes up this directory. Now it's new room for
2286 the new set of documenation files.
2287 [Ralf S. Engelschall]
2289 *) SETs were incorrectly DER encoded. This was a major pain, because they
2290 shared code with SEQUENCEs, which aren't coded the same. This means that
2291 almost everything to do with SETs or SEQUENCEs has either changed name or
2292 number of arguments.
2293 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
2295 *) Fix test data to work with the above.
2298 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
2299 was already fixed by Eric for 0.9.1 it seems.
2300 [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
2302 *) Autodetect FreeBSD3.
2305 *) Fix various bugs in Configure. This affects the following platforms:
2309 unixware-2.0-pentium
2313 *) Eliminate generated files from CVS. Reorder tests to regenerate files
2314 before they are needed.
2317 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
2321 Changes between 0.9.1b and 0.9.1c [23-Dec-1998]
2323 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
2324 changed SSLeay to OpenSSL in version strings.
2325 [Ralf S. Engelschall]
2327 *) Some fixups to the top-level documents.
2330 *) Fixed the nasty bug where rsaref.h was not found under compile-time
2331 because the symlink to include/ was missing.
2332 [Ralf S. Engelschall]
2334 *) Incorporated the popular no-RSA/DSA-only patches
2335 which allow to compile a RSA-free SSLeay.
2336 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
2338 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
2339 when "ssleay" is still not found.
2340 [Ralf S. Engelschall]
2342 *) Added more platforms to Configure: Cray T3E, HPUX 11,
2343 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
2345 *) Updated the README file.
2346 [Ralf S. Engelschall]
2348 *) Added various .cvsignore files in the CVS repository subdirs
2349 to make a "cvs update" really silent.
2350 [Ralf S. Engelschall]
2352 *) Recompiled the error-definition header files and added
2353 missing symbols to the Win32 linker tables.
2354 [Ralf S. Engelschall]
2356 *) Cleaned up the top-level documents;
2357 o new files: CHANGES and LICENSE
2358 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
2359 o merged COPYRIGHT into LICENSE
2360 o removed obsolete TODO file
2361 o renamed MICROSOFT to INSTALL.W32
2362 [Ralf S. Engelschall]
2364 *) Removed dummy files from the 0.9.1b source tree:
2365 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
2366 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f
2367 crypto/pem/gmon.out crypto/perlasm/f crypto/pkcs7/build crypto/rsa/f
2368 crypto/sha/asm/f crypto/threads/f ms/zzz ssl/f ssl/f.mak test/f
2369 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
2370 [Ralf S. Engelschall]
2372 *) Added various platform portability fixes.
2375 *) The Genesis of the OpenSSL rpject:
2376 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
2377 Young and Tim J. Hudson created while they were working for C2Net until
2379 [The OpenSSL Project]
2382 Changes between 0.9.0b and 0.9.1b [not released]
2384 *) Updated a few CA certificates under certs/
2387 *) Changed some BIGNUM api stuff.
2390 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
2391 DGUX x86, Linux Alpha, etc.
2394 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
2395 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
2399 *) Add -strparse option to asn1pars program which parses nested
2401 [Dr Stephen Henson <shenson@bigfoot.com>]
2403 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
2406 *) DSA fix for "ca" program.
2409 *) Added "-genkey" option to "dsaparam" program.
2412 *) Added RIPE MD160 (rmd160) message digest.
2415 *) Added -a (all) option to "ssleay version" command.
2418 *) Added PLATFORM define which is the id given to Configure.
2421 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
2424 *) Extended the ASN.1 parser routines.
2427 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
2430 *) Added a BN_CTX to the BN library.
2433 *) Fixed the weak key values in DES library
2436 *) Changed API in EVP library for cipher aliases.
2439 *) Added support for RC2/64bit cipher.
2442 *) Converted the lhash library to the crypto/mem.c functions.
2445 *) Added more recognized ASN.1 object ids.
2448 *) Added more RSA padding checks for SSL/TLS.
2451 *) Added BIO proxy/filter functionality.
2454 *) Added extra_certs to SSL_CTX which can be used
2455 send extra CA certificates to the client in the CA cert chain sending
2456 process. It can be configured with SSL_CTX_add_extra_chain_cert().
2459 *) Now Fortezza is denied in the authentication phase because
2460 this is key exchange mechanism is not supported by SSLeay at all.
2463 *) Additional PKCS1 checks.
2466 *) Support the string "TLSv1" for all TLS v1 ciphers.
2469 *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
2470 ex_data index of the SSL context in the X509_STORE_CTX ex_data.
2473 *) Fixed a few memory leaks.
2476 *) Fixed various code and comment typos.
2479 *) A minor bug in ssl/s3_clnt.c where there would always be 4 0
