5 Changes between 0.9.6 and 0.9.7 [xx XXX 2000]
7 *) Fix bug in PKCS#12 key generation routines. This was triggered
8 if a 3DES key was generated with a 0 initial byte. Include
9 PKCS12_BROKEN_KEYGEN compilation option to retain the old
10 (but broken) behaviour.
13 *) Enhance bctest to search for a working bc along $PATH and print
15 [Tim Rice <tim@multitalents.net> via Richard Levitte]
17 *) Add a 'copy_extensions' option to the 'ca' utility. This copies
18 extensions from a certificate request to the certificate.
21 *) Allow multiple 'certopt' and 'nameopt' options to be separated
22 by commas. Add 'namopt' and 'certopt' options to the 'ca' config
23 file: this allows the display of the certificate about to be
24 signed to be customised, to allow certain fields to be included
25 or excluded and extension details. The old system didn't display
26 multicharacter strings properly, omitted fields not in the policy
27 and couldn't display additional details such as extensions.
30 *) Fix memory leaks in err.c: free err_data string if necessary;
31 don't write to the wrong index in ERR_set_error_data.
34 *) Function EC_POINTs_mul for simultaneous scalar multiplication
35 of an arbitrary number of elliptic curve points, optionally
36 including the generator defined for the EC_GROUP.
37 EC_POINT_mul is a simple wrapper function for the typical case
38 that the point list has just one item (besides the optional
42 *) First EC_METHODs for curves over GF(p):
44 EC_GFp_simple_method() uses the basic BN_mod_mul and BN_mod_sqr
45 operations and provides various method functions that can also
46 operate with faster implementations of modular arithmetic.
48 EC_GFp_mont_method() reuses most functions that are part of
49 EC_GFp_simple_method, but uses Montgomery arithmetic.
51 [Bodo Moeller; point addition and point doubling
52 implementation directly derived from source code provided by
53 Lenka Fibikova <fibikova@exp-math.uni-essen.de>]
55 *) Framework for elliptic curves (crypto/ec/ec.h, crypto/ec/ec_lcl.h,
58 Curves are EC_GROUP objects (with an optional group generator)
59 based on EC_METHODs that are built into the library.
61 Points are EC_POINT objects based on EC_GROUP objects.
63 Most of the framework would be able to handle curves over arbitrary
64 finite fields, but as there are no obvious types for fields other
65 than GF(p), some functions are limited to that for now.
68 *) Add the -HTTP option to s_server. It is similar to -WWW, but requires
69 that the file contains a complete HTTP response.
72 *) Add the ec directory to mkdef.pl and mkfiles.pl. In mkdef.pl
73 change the def and num file printf format specifier from "%-40sXXX"
74 to "%-39s XXX". The latter will always guarantee a space after the
75 field while the former will cause them to run together if the field
76 is 40 of more characters long.
79 *) Constify the cipher and digest 'method' functions and structures
80 and modify related functions to take constant EVP_MD and EVP_CIPHER
84 *) Implement ssl23_peek (analogous to ssl23_read), which previously
88 *) Replace rdtsc with _emit statements for VC++ version 5.
89 [Jeremy Cooper <jeremy@baymoo.org>]
91 *) Hide BN_CTX structure details in bn_lcl.h instead of publishing them
92 in <openssl/bn.h>. Also further increase BN_CTX_NUM to 32.
95 *) Modify EVP_Digest*() routines so they now return values. Although the
96 internal software routines can never fail additional hardware versions
100 *) Clean up crypto/err/err.h and change some error codes to avoid conflicts:
102 Previously ERR_R_FATAL was too small and coincided with ERR_LIB_PKCS7
103 (= ERR_R_PKCS7_LIB); it is now 64 instead of 32.
106 ERR_R_NESTED_ASN1_ERROR
108 ERR_R_MISSING_ASN1_EOS
109 were 4 .. 9, conflicting with
110 ERR_LIB_RSA (= ERR_R_RSA_LIB)
112 ERR_LIB_PEM (= ERR_R_PEM_LIB).
113 They are now 58 .. 63 (i.e., just below ERR_R_FATAL).
115 Add new error code 'ERR_R_INTERNAL_ERROR'.
118 *) Don't overuse locks in crypto/err/err.c: For data retrieval, CRYPTO_r_lock
122 *) New option '-subj arg' for 'openssl req' and 'openssl ca'. This
123 sets the subject name for a new request or supersedes the
124 subject name in a given request. Formats that can be parsed are
125 'CN=Some Name, OU=myOU, C=IT'
127 'CN=Some Name/OU=myOU/C=IT'.
129 Add options '-batch' and '-verbose' to 'openssl req'.
130 [Massimiliano Pala <madwolf@hackmasters.net>]
132 *) Make it possible to reuse SSLv2 sessions.
135 *) Introduce the possibility to access global variables through
136 functions on platform were that's the best way to handle exporting
137 global variables in shared libraries. To enable this functionality,
138 one must configure with "EXPORT_VAR_AS_FN" or defined the C macro
139 "OPENSSL_EXPORT_VAR_AS_FUNCTION" in crypto/opensslconf.h (the latter
140 is normally done by Configure or something similar).
142 To implement a global variable, use the macro OPENSSL_IMPLEMENT_GLOBAL
143 in the source file (foo.c) like this:
145 OPENSSL_IMPLEMENT_GLOBAL(int,foo)=1;
146 OPENSSL_IMPLEMENT_GLOBAL(double,bar);
148 To declare a global variable, use the macros OPENSSL_DECLARE_GLOBAL
149 and OPENSSL_GLOBAL_REF in the header file (foo.h) like this:
151 OPENSSL_DECLARE_GLOBAL(int,foo);
152 #define foo OPENSSL_GLOBAL_REF(foo)
153 OPENSSL_DECLARE_GLOBAL(double,bar);
154 #define bar OPENSSL_GLOBAL_REF(bar)
156 The #defines are very important, and therefore so is including the
157 header file everywere where the defined globals are used.
159 The macro OPENSSL_EXPORT_VAR_AS_FUNCTION also affects the definition
160 of ASN.1 items, but that structure is a bt different.
162 The largest change is in util/mkdef.pl which has been enhanced with
163 better and easier to understand logic to choose which symbols should
164 go into the Windows .def files as well as a number of fixes and code
165 cleanup (among others, algorithm keywords are now sorted
166 lexicographically to avoid constant rewrites).
169 *) In copy_email() check for >= 0 as a return value for
170 X509_NAME_get_index_by_NID() since 0 is a valid index.
171 [Steve Henson reported by Massimiliano Pala <madwolf@opensca.org>]
173 *) In BN_div() keep a copy of the sign of 'num' before writing the
174 result to 'rm' because if rm==num the value will be overwritten
175 and produce the wrong result if 'num' is negative: this caused
176 problems with BN_mod() and BN_nnmod().
179 *) Function OCSP_request_verify(). This checks the signature on an
180 OCSP request and verifies the signer certificate. The signer
181 certificate is just checked for a generic purpose and OCSP request
185 *) Add OCSP_check_validity() function to check the validity of OCSP
186 responses. OCSP responses are prepared in real time and may only
187 be a few seconds old. Simply checking that the current time lies
188 between thisUpdate and nextUpdate max reject otherwise valid responses
189 caused by either OCSP responder or client clock innacuracy. Instead
190 we allow thisUpdate and nextUpdate to fall within a certain period of
191 the current time. The age of the response can also optionally be
192 checked. Two new options -validity_period and -status_age added to
196 *) If signature or public key algorithm is unrecognized print out its
197 OID rather that just UNKOWN.
200 *) Avoid coredump with unsupported or invalid public keys by checking if
201 X509_get_pubkey() fails in PKCS7_verify(). Fix memory leak when
202 PKCS7_verify() fails with non detached data.
205 *) Change OCSP_cert_to_id() to tolerate a NULL subject certificate and
206 OCSP_cert_id_new() a NULL serialNumber. This allows a partial certificate
207 ID to be generated from the issuer certificate alone which can then be
208 passed to OCSP_id_issuer_cmp().
211 *) New compilation option ASN1_ITEM_FUNCTIONS. This causes the new
212 ASN1 modules to export functions returning ASN1_ITEM pointers
213 instead of the ASN1_ITEM structures themselves. This adds several
214 new macros which allow the underlying ASN1 function/structure to
215 be accessed transparently. As a result code should not use ASN1_ITEM
216 references directly (such as &X509_it) but instead use the relevant
217 macros (such as ASN1_ITEM_rptr(X509)). This option is to allow
218 use of the new ASN1 code on platforms where exporting structures
219 is problematical (for example in shared libraries) but exporting
220 functions returning pointers to structures is not.
223 *) Add support for overriding the generation of SSL/TLS session IDs.
224 These callbacks can be registered either in an SSL_CTX or per SSL.
225 The purpose of this is to allow applications to control, if they wish,
226 the arbitrary values chosen for use as session IDs, particularly as it
227 can be useful for session caching in multiple-server environments. A
228 command-line switch for testing this (and any client code that wishes
229 to use such a feature) has been added to "s_server".
230 [Geoff Thorpe, Lutz Jaenicke]
232 *) Modify mkdef.pl to recognise and parse prprocessor conditionals
233 of the form '#if defined(...) || defined(...) || ...' and
234 '#if !defined(...) && !defined(...) && ...'. This also avoids
235 the growing number of special cases it was previously handling.
238 *) Don't use getenv in library functions when run as setuid/setgid.
239 New function OPENSSL_issetugid().
242 *) Make all configuration macros available for application by making
243 sure they are available in opensslconf.h, by giving them names starting
244 with "OPENSSL_" to avoid conflicts with other packages and by making
245 sure e_os2.h will cover all platform-specific cases together with
247 Additionally, it is now possible to define configuration/platform-
248 specific names (called "system identities"). In the C code, these
249 are prefixed with "OPENSSL_SYSNAME_". e_os2.h will create another
250 macro with the name beginning with "OPENSSL_SYS_", which is determined
251 from "OPENSSL_SYSNAME_*" or compiler-specific macros depending on
255 *) New option -set_serial to 'req' and 'x509' this allows the serial
256 number to use to be specified on the command line. Previously self
257 signed certificates were hard coded with serial number 0 and the
258 CA options of 'x509' had to use a serial number in a file which was
262 *) Avoid false positives in memory leak detection code (crypto/mem_dbg.c)
263 due to incorrect handling of multi-threading:
265 1. Fix timing glitch in the MemCheck_off() portion of CRYPTO_mem_ctrl().
267 2. Fix logical glitch in is_MemCheck_on() aka CRYPTO_is_mem_check_on().
269 3. Count how many times MemCheck_off() has been called so that
270 nested use can be treated correctly. This also avoids
271 inband-signalling in the previous code (which relied on the
272 assumption that thread ID 0 is impossible).
275 *) New options to 'ca' utility to support V2 CRL entry extensions.
276 Currently CRL reason, invalidity date and hold instruction are
277 supported. Add new CRL extensions to V3 code and some new objects.
280 *) Add "-rand" option also to s_client and s_server.
283 *) New function EVP_CIPHER_CTX_set_padding() this is used to
284 disable standard block padding (aka PKCS#5 padding) in the EVP
285 API, which was previously mandatory. This means that the data is
286 not padded in any way and so the total length much be a multiple
287 of the block size, otherwise an error occurs.
290 *) Initial (incomplete) OCSP SSL support.
293 *) Fix CPU detection on Irix 6.x.
294 [Kurt Hockenbury <khockenb@stevens-tech.edu> and
295 "Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
297 *) New function OCSP_parse_url(). This splits up a URL into its host,
298 port and path components: primarily to parse OCSP URLs. New -url
299 option to ocsp utility.
302 *) New nonce behavior. The return value of OCSP_check_nonce() now
303 reflects the various checks performed. Applications can decide
304 whether to tolerate certain situations such as an absent nonce
305 in a response when one was present in a request: the ocsp application
306 just prints out a warning. New function OCSP_add1_basic_nonce()
307 this is to allow responders to include a nonce in a response even if
308 the request is nonce-less.
311 *) Use the cached encoding of an X509_NAME structure rather than
312 copying it. This is apparently the reason for the libsafe "errors"
313 but the code is actually correct.
316 *) Disable stdin buffering in load_cert (apps/apps.c) so that no certs are
317 skipped when using openssl x509 multiple times on a single input file,
318 e.g. "(openssl x509 -out cert1; openssl x509 -out cert2) <certs".
321 *) Make ASN1_UTCTIME_set_string() and ASN1_GENERALIZEDTIME_set_string()
322 set string type: to handle setting ASN1_TIME structures. Fix ca
323 utility to correctly initialize revocation date of CRLs.
326 *) New option SSL_OP_CIPHER_SERVER_PREFERENCE allows the server to override
327 the clients preferred ciphersuites and rather use its own preferences.
328 Should help to work around M$ SGC (Server Gated Cryptography) bug in
329 Internet Explorer by ensuring unchanged hash method during stepup.
332 *) Make mkdef.pl recognise all DECLARE_ASN1 macros, change rijndael
333 to aes and add a new 'exist' option to print out symbols that don't
337 *) Additional options to ocsp utility to allow flags to be set and
338 additional certificates supplied.
341 *) Add the option -VAfile to 'openssl ocsp', so the user can give the
342 OCSP client a number of certificate to only verify the response
346 *) Add new function BN_rand_range(), and fix DSA_sign_setup() to prevent
347 Bleichenbacher's DSA attack.
348 Extend BN_[pseudo_]rand: As before, top=1 forces the highest two bits
349 to be set and top=0 forces the highest bit to be set; top=-1 is new
350 and leaves the highest bit random.
351 [Ulf Moeller, Bodo Moeller]
353 *) Update Rijndael code to version 3.0 and change EVP AES ciphers to
354 handle the new API. Currently only ECB, CBC modes supported. Add new
355 AES OIDs. Add TLS AES ciphersuites as described in the "AES Ciphersuites
356 for TLS" draft-ietf-tls-ciphersuite-03.txt.
357 [Ben Laurie, Steve Henson]
359 *) In the NCONF_...-based implementations for CONF_... queries
360 (crypto/conf/conf_lib.c), if the input LHASH is NULL, avoid using
361 a temporary CONF structure with the data component set to NULL
362 (which gives segmentation faults in lh_retrieve).
363 Instead, use NULL for the CONF pointer in CONF_get_string and
364 CONF_get_number (which may use environment variables) and directly
365 return NULL from CONF_get_section.
368 *) Fix potential buffer overrun for EBCDIC.
371 *) New function OCSP_copy_nonce() to copy nonce value (if present) from
375 *) Functions for OCSP responders. OCSP_request_onereq_count(),
376 OCSP_request_onereq_get0(), OCSP_onereq_get0_id() and OCSP_id_get0_info()
377 extract information from a certificate request. OCSP_response_create()
378 creates a response and optionally adds a basic response structure.
379 OCSP_basic_add1_status() adds a complete single response to a basic
380 reponse and returns the OCSP_SINGLERESP structure just added (to allow
381 extensions to be included for example). OCSP_basic_add1_cert() adds a
382 certificate to a basic response and OCSP_basic_sign() signs a basic
383 response with various flags. New helper functions ASN1_TIME_check()
384 (checks validity of ASN1_TIME structure) and ASN1_TIME_to_generalizedtime()
385 (converts ASN1_TIME to GeneralizedTime).
388 *) Various new functions. EVP_Digest() combines EVP_Digest{Init,Update,Final}()
389 in a single operation. X509_get0_pubkey_bitstr() extracts the public_key
390 structure from a certificate. X509_pubkey_digest() digests tha public_key
391 contents: this is used in various key identifiers.
394 *) Tolerate nonRepudiation as being valid for S/MIME signing and certSign
395 keyUsage if basicConstraints absent for a CA.
398 *) Make SMIME_write_PKCS7() write mail header values with a format that
399 is more generally accepted (no spaces before the semicolon), since
400 some programs can't parse those values properly otherwise. Also make
401 sure BIO's that break lines after each write do not create invalid
405 *) Make sk_sort() tolerate a NULL argument.
406 [Steve Henson reported by Massimiliano Pala <madwolf@comune.modena.it>]
408 *) New OCSP verify flag OCSP_TRUSTOTHER. When set the "other" certificates
409 passed by the function are trusted implicitly. If any of them signed the
410 reponse then it is assumed to be valid and is not verified.
413 *) Zero the premaster secret after deriving the master secret in
417 *) In PKCS7_set_type() initialise content_type in PKCS7_ENC_CONTENT
418 to data. This was previously part of the PKCS7 ASN1 code. This
419 was causing problems with OpenSSL created PKCS#12 and PKCS#7 structures.
420 [Steve Henson, reported by Kenneth R. Robinette
421 <support@securenetterm.com>]
423 *) Add CRYPTO_push_info() and CRYPTO_pop_info() calls to new ASN1
424 routines: without these tracing memory leaks is very painful.
425 Fix leaks in PKCS12 and PKCS7 routines.
428 *) Add some EVP_add_digest_alias registrations (as found in
429 OpenSSL_add_all_digests()) to SSL_library_init()
430 aka OpenSSL_add_ssl_algorithms(). This provides improved
431 compatibility with peers using X.509 certificates
432 with unconventional AlgorithmIdentifier OIDs.
435 *) Fix for Irix with NO_ASM.
436 ["Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
438 *) ./config script fixes.
439 [Ulf Moeller, Richard Levitte]
441 *) Make X509_time_adj() cope with the new behaviour of ASN1_TIME_new().
442 Previously it initialised the 'type' argument to V_ASN1_UTCTIME which
443 effectively meant GeneralizedTime would never be used. Now it
444 is initialised to -1 but X509_time_adj() now has to check the value
445 and use ASN1_TIME_set() if the value is not V_ASN1_UTCTIME or
446 V_ASN1_GENERALIZEDTIME, without this it always uses GeneralizedTime.
447 [Steve Henson, reported by Kenneth R. Robinette
448 <support@securenetterm.com>]
450 *) Fixes to BN_to_ASN1_INTEGER when bn is zero. This would previously
451 result in a zero length in the ASN1_INTEGER structure which was
452 not consistent with the structure when d2i_ASN1_INTEGER() was used
453 and would cause ASN1_INTEGER_cmp() to fail. Enhance s2i_ASN1_INTEGER()
454 to cope with hex and negative integers. Fix bug in i2a_ASN1_INTEGER()
455 where it did not print out a minus for negative ASN1_INTEGER.
458 *) Fix 'openssl passwd -1'.
461 *) Add summary printout to ocsp utility. The various functions which
462 convert status values to strings have been renamed to:
463 OCSP_response_status_str(), OCSP_cert_status_str() and
464 OCSP_crl_reason_str() and are no longer static. New options
465 to verify nonce values and to disable verification. OCSP response
466 printout format cleaned up.
469 *) Add additional OCSP certificate checks. These are those specified
470 in RFC2560. This consists of two separate checks: the CA of the
471 certificate being checked must either be the OCSP signer certificate
472 or the issuer of the OCSP signer certificate. In the latter case the
473 OCSP signer certificate must contain the OCSP signing extended key
474 usage. This check is performed by attempting to match the OCSP
475 signer or the OCSP signer CA to the issuerNameHash and issuerKeyHash
476 in the OCSP_CERTID structures of the response.
479 *) Initial OCSP certificate verification added to OCSP_basic_verify()
480 and related routines. This uses the standard OpenSSL certificate
481 verify routines to perform initial checks (just CA validity) and
482 to obtain the certificate chain. Then additional checks will be
483 performed on the chain. Currently the root CA is checked to see
484 if it is explicitly trusted for OCSP signing. This is used to set
485 a root CA as a global signing root: that is any certificate that
486 chains to that CA is an acceptable OCSP signing certificate.
489 *) New '-extfile ...' option to 'openssl ca' for reading X.509v3
490 extensions from a separate configuration file.
491 As when reading extensions from the main configuration file,
492 the '-extensions ...' option may be used for specifying the
494 [Massimiliano Pala <madwolf@comune.modena.it>]
496 *) Change PKCS12_key_gen_asc() so it can cope with non null
497 terminated strings whose length is passed in the passlen
498 parameter, for example from PEM callbacks. This was done
499 by adding an extra length parameter to asc2uni().
500 [Steve Henson, reported by <oddissey@samsung.co.kr>]
502 *) New OCSP utility. Allows OCSP requests to be generated or
503 read. The request can be sent to a responder and the output
504 parsed, outputed or printed in text form. Not complete yet:
505 still needs to check the OCSP response validity.
508 *) New subcommands for 'openssl ca':
509 'openssl ca -status <serial>' prints the status of the cert with
510 the given serial number (according to the index file).
511 'openssl ca -updatedb' updates the expiry status of certificates
513 [Massimiliano Pala <madwolf@comune.modena.it>]
515 *) New '-newreq-nodes' command option to CA.pl. This is like
516 '-newreq', but calls 'openssl req' with the '-nodes' option
517 so that the resulting key is not encrypted.
518 [Damien Miller <djm@mindrot.org>]
520 *) New configuration for the GNU Hurd.
521 [Jonathan Bartlett <johnnyb@wolfram.com> via Richard Levitte]
523 *) Initial code to implement OCSP basic response verify. This
524 is currently incomplete. Currently just finds the signer's
525 certificate and verifies the signature on the response.
528 *) New SSLeay_version code SSLEAY_DIR to determine the compiled-in
529 value of OPENSSLDIR. This is available via the new '-d' option
530 to 'openssl version', and is also included in 'openssl version -a'.
533 *) Fix C code generated by 'openssl dsaparam -C': If a BN_bin2bn
534 call failed, free the DSA structure.
537 *) Allowing defining memory allocation callbacks that will be given
538 file name and line number information in additional arguments
539 (a const char* and an int). The basic functionality remains, as
540 well as the original possibility to just replace malloc(),
541 realloc() and free() by functions that do not know about these
542 additional arguments. To register and find out the current
543 settings for extended allocation functions, the following
544 functions are provided:
546 CRYPTO_set_mem_ex_functions
547 CRYPTO_set_locked_mem_ex_functions
548 CRYPTO_get_mem_ex_functions
549 CRYPTO_get_locked_mem_ex_functions
551 These work the same way as CRYPTO_set_mem_functions and friends.
552 CRYPTO_get_[locked_]mem_functions now writes 0 where such an
553 extended allocation function is enabled.
554 Similarly, CRYPTO_get_[locked_]mem_ex_functions writes 0 where
555 a conventional allocation function is enabled.
556 [Richard Levitte, Bodo Moeller]
558 *) Fix to uni2asc() to cope with zero length Unicode strings.
559 These are present in some PKCS#12 files.
562 *) Finish off removing the remaining LHASH function pointer casts.
563 There should no longer be any prototype-casting required when using
564 the LHASH abstraction, and any casts that remain are "bugs". See
565 the callback types and macros at the head of lhash.h for details
566 (and "OBJ_cleanup" in crypto/objects/obj_dat.c as an example).
569 *) Add automatic query of EGD sockets in RAND_poll() for the unix variant.
570 If an EGD or PRNGD is running and enough entropy is returned, automatic
571 seeding like with /dev/[u]random will be performed.
572 Positions tried are: /etc/entropy, /var/run/egd-pool.
575 *) Change the Unix RAND_poll() variant to be able to poll several
576 random devices, as specified by DEVRANDOM, until a sufficient amount
577 of data has been collected. We spend at most 10 ms on each file
578 (select timeout) and read in non-blocking mode. DEVRANDOM now
579 defaults to the list "/dev/urandom", "/dev/random", "/dev/srandom"
580 (previously it was just the string "/dev/urandom"), so on typical
581 platforms the 10 ms delay will never occur.
582 Also separate out the Unix variant to its own file, rand_unix.c.
583 For VMS, there's a currently-empty rand_vms.c.
586 *) Move OCSP client related routines to ocsp_cl.c. These
587 provide utility functions which an application needing
588 to issue a request to an OCSP responder and analyse the
589 response will typically need: as opposed to those which an
590 OCSP responder itself would need which will be added later.
592 OCSP_request_sign() signs an OCSP request with an API similar
593 to PKCS7_sign(). OCSP_response_status() returns status of OCSP
594 response. OCSP_response_get1_basic() extracts basic response
595 from response. OCSP_resp_find_status(): finds and extracts status
596 information from an OCSP_CERTID structure (which will be created
597 when the request structure is built). These are built from lower
598 level functions which work on OCSP_SINGLERESP structures but
599 wont normally be used unless the application wishes to examine
600 extensions in the OCSP response for example.
602 Replace nonce routines with a pair of functions.
603 OCSP_request_add1_nonce() adds a nonce value and optionally
604 generates a random value. OCSP_check_nonce() checks the
605 validity of the nonce in an OCSP response.
608 *) Change function OCSP_request_add() to OCSP_request_add0_id().
609 This doesn't copy the supplied OCSP_CERTID and avoids the
610 need to free up the newly created id. Change return type
611 to OCSP_ONEREQ to return the internal OCSP_ONEREQ structure.
612 This can then be used to add extensions to the request.
613 Deleted OCSP_request_new(), since most of its functionality
614 is now in OCSP_REQUEST_new() (and the case insensitive name
615 clash) apart from the ability to set the request name which
616 will be added elsewhere.
619 *) Update OCSP API. Remove obsolete extensions argument from
620 various functions. Extensions are now handled using the new
621 OCSP extension code. New simple OCSP HTTP function which
622 can be used to send requests and parse the response.
625 *) Fix the PKCS#7 (S/MIME) code to work with new ASN1. Two new
626 ASN1_ITEM structures help with sign and verify. PKCS7_ATTR_SIGN
627 uses the special reorder version of SET OF to sort the attributes
628 and reorder them to match the encoded order. This resolves a long
629 standing problem: a verify on a PKCS7 structure just after signing
630 it used to fail because the attribute order did not match the
631 encoded order. PKCS7_ATTR_VERIFY does not reorder the attributes:
632 it uses the received order. This is necessary to tolerate some broken
633 software that does not order SET OF. This is handled by encoding
634 as a SEQUENCE OF but using implicit tagging (with UNIVERSAL class)
635 to produce the required SET OF.
638 *) Have mk1mf.pl generate the macros OPENSSL_BUILD_SHLIBCRYPTO and
639 OPENSSL_BUILD_SHLIBSSL and use them appropriately in the header
640 files to get correct declarations of the ASN.1 item variables.
643 *) Rewrite of PKCS#12 code to use new ASN1 functionality. Replace many
644 PKCS#12 macros with real functions. Fix two unrelated ASN1 bugs:
645 asn1_check_tlen() would sometimes attempt to use 'ctx' when it was
646 NULL and ASN1_TYPE was not dereferenced properly in asn1_ex_c2i().
647 New ASN1 macro: DECLARE_ASN1_ITEM() which just declares the relevant
648 ASN1_ITEM and no wrapper functions.
651 *) New functions or ASN1_item_d2i_fp() and ASN1_item_d2i_bio(). These
652 replace the old function pointer based I/O routines. Change most of
653 the *_d2i_bio() and *_d2i_fp() functions to use these.
656 *) Enhance mkdef.pl to be more accepting about spacing in C preprocessor
657 lines, recognice more "algorithms" that can be deselected, and make
658 it complain about algorithm deselection that isn't recognised.
661 *) New ASN1 functions to handle dup, sign, verify, digest, pack and
662 unpack operations in terms of ASN1_ITEM. Modify existing wrappers
663 to use new functions. Add NO_ASN1_OLD which can be set to remove
664 some old style ASN1 functions: this can be used to determine if old
665 code will still work when these eventually go away.
668 *) New extension functions for OCSP structures, these follow the
669 same conventions as certificates and CRLs.
672 *) New function X509V3_add1_i2d(). This automatically encodes and
673 adds an extension. Its behaviour can be customised with various
674 flags to append, replace or delete. Various wrappers added for
675 certifcates and CRLs.
678 *) Fix to avoid calling the underlying ASN1 print routine when
679 an extension cannot be parsed. Correct a typo in the
680 OCSP_SERVICELOC extension. Tidy up print OCSP format.
683 *) Increase s2->wbuf allocation by one byte in ssl2_new (ssl/s2_lib.c).
684 Otherwise do_ssl_write (ssl/s2_pkt.c) will write beyond buffer limits
685 when writing a 32767 byte record.
686 [Bodo Moeller; problem reported by Eric Day <eday@concentric.net>]
688 *) In RSA_eay_public_{en,ed}crypt and RSA_eay_mod_exp (rsa_eay.c),
689 obtain lock CRYPTO_LOCK_RSA before setting rsa->_method_mod_{n,p,q}.
691 (RSA objects have a reference count access to which is protected
692 by CRYPTO_LOCK_RSA [see rsa_lib.c, s3_srvr.c, ssl_cert.c, ssl_rsa.c],
693 so they are meant to be shared between threads.)
694 [Bodo Moeller, Geoff Thorpe; original patch submitted by
695 "Reddie, Steven" <Steven.Reddie@ca.com>]
697 *) Make mkdef.pl parse some of the ASN1 macros and add apropriate
698 entries for variables.
701 *) Fix a deadlock in CRYPTO_mem_leaks().
704 *) Add functionality to apps/openssl.c for detecting locking
705 problems: As the program is single-threaded, all we have
706 to do is register a locking callback using an array for
707 storing which locks are currently held by the program.
710 *) Use a lock around the call to CRYPTO_get_ex_new_index() in
711 SSL_get_ex_data_X509_STORE_idx(), which is used in
712 ssl_verify_cert_chain() and thus can be called at any time
713 during TLS/SSL handshakes so that thread-safety is essential.
714 Unfortunately, the ex_data design is not at all suited
715 for multi-threaded use, so it probably should be abolished.
718 *) Added Broadcom "ubsec" ENGINE to OpenSSL.
719 [Broadcom, tweaked and integrated by Geoff Thorpe]
721 *) Move common extension printing code to new function
722 X509V3_print_extensions(). Reorganise OCSP print routines and
723 implement some needed OCSP ASN1 functions. Add OCSP extensions.
726 *) New function X509_signature_print() to remove duplication in some
730 *) Add a special meaning when SET OF and SEQUENCE OF flags are both
731 set (this was treated exactly the same as SET OF previously). This
732 is used to reorder the STACK representing the structure to match the
733 encoding. This will be used to get round a problem where a PKCS7
734 structure which was signed could not be verified because the STACK
735 order did not reflect the encoded order.
738 *) Reimplement the OCSP ASN1 module using the new code.
741 *) Update the X509V3 code to permit the use of an ASN1_ITEM structure
742 for its ASN1 operations. The old style function pointers still exist
743 for now but they will eventually go away.
746 *) Merge in replacement ASN1 code from the ASN1 branch. This almost
747 completely replaces the old ASN1 functionality with a table driven
748 encoder and decoder which interprets an ASN1_ITEM structure describing
749 the ASN1 module. Compatibility with the existing ASN1 API (i2d,d2i) is
750 largely maintained. Almost all of the old asn1_mac.h macro based ASN1
751 has also been converted to the new form.
754 *) Change BN_mod_exp_recp so that negative moduli are tolerated
755 (the sign is ignored). Similarly, ignore the sign in BN_MONT_CTX_set
756 so that BN_mod_exp_mont and BN_mod_exp_mont_word work
760 *) Fix BN_uadd and BN_usub: Always return non-negative results instead
761 of not touching the result's sign bit.
764 *) BN_div bugfix: If the result is 0, the sign (res->neg) must not be
768 *) Changed the LHASH code to use prototypes for callbacks, and created
769 macros to declare and implement thin (optionally static) functions
770 that provide type-safety and avoid function pointer casting for the
771 type-specific callbacks.
774 *) Use better test patterns in bntest.
777 *) Added Kerberos Cipher Suites to be used with TLS, as written in
779 [Veers Staats <staatsvr@asc.hpc.mil>,
780 Jeffrey Altman <jaltman@columbia.edu>, via Richard Levitte]
782 *) rand_win.c fix for Borland C.
785 *) BN_rshift bugfix for n == 0.
788 *) Reformat the FAQ so the different questions and answers can be divided
789 in sections depending on the subject.
792 *) Have the zlib compression code load ZLIB.DLL dynamically under
796 *) New function BN_mod_sqrt for computing square roots modulo a prime
797 (using the probabilistic Tonelli-Shanks algorithm unless
798 p == 3 (mod 4) or p == 5 (mod 8), which are cases that can
799 be handled deterministically).
800 [Lenka Fibikova <fibikova@exp-math.uni-essen.de>, Bodo Moeller]
802 *) Add a 'bctest' script that checks for some known 'bc' bugs
803 so that 'make test' does not abort just because 'bc' is broken.
806 *) Store verify_result within SSL_SESSION also for client side to
807 avoid potential security hole. (Re-used sessions on the client side
808 always resulted in verify_result==X509_V_OK, not using the original
809 result of the server certificate verification.)
812 *) Make BN_mod_inverse faster by explicitly handling small quotients
813 in the Euclid loop. (Speed gain about 20% for small moduli [256 or
814 512 bits], about 30% for larger ones [1024 or 2048 bits].)
817 *) Fix ssl3_pending: If the record in s->s3->rrec is not of type
818 SSL3_RT_APPLICATION_DATA, return 0.
819 Similarly, change ssl2_pending to return 0 if SSL_in_init(s) is true.
823 Both ssl2_peek and ssl3_peek, which were totally broken in earlier
824 releases, have been re-implemented by renaming the previous
825 implementations of ssl2_read and ssl3_read to ssl2_read_internal
826 and ssl3_read_internal, respectively, and adding 'peek' parameters
827 to them. The new ssl[23]_{read,peek} functions are calls to
828 ssl[23]_read_internal with the 'peek' flag set appropriately.
829 A 'peek' parameter has also been added to ssl3_read_bytes, which
830 does the actual work for ssl3_read_internal.
833 *) New function BN_kronecker.
836 *) Fix BN_gcd so that it works on negative inputs; the result is
837 positive unless both parameters are zero.
838 Previously something reasonably close to an infinite loop was
839 possible because numbers could be growing instead of shrinking
840 in the implementation of Euclid's algorithm.
843 *) Fix BN_is_word() and BN_is_one() macros to take into account the
844 sign of the number in question.
846 Fix BN_is_word(a,w) to work correctly for w == 0.
848 The old BN_is_word(a,w) macro is now called BN_abs_is_word(a,w)
849 because its test if the absolute value of 'a' equals 'w'.
850 Note that BN_abs_is_word does *not* handle w == 0 reliably;
851 it exists mostly for use in the implementations of BN_is_zero(),
852 BN_is_one(), and BN_is_word().
855 *) Initialise "ex_data" member of RSA/DSA/DH structures prior to calling
856 the method-specific "init()" handler. Also clean up ex_data after
857 calling the method-specific "finish()" handler. Previously, this was
858 happening the other way round.
861 *) New function BN_swap.
864 *) Use BN_nnmod instead of BN_mod in crypto/bn/bn_exp.c so that
865 the exponentiation functions are more likely to produce reasonable
866 results on negative inputs.
869 *) Change BN_mod_mul so that the result is always non-negative.
870 Previously, it could be negative if one of the factors was negative;
871 I don't think anyone really wanted that behaviour.
874 *) Move BN_mod_... functions into new file crypto/bn/bn_mod.c
875 (except for exponentiation, which stays in crypto/bn/bn_exp.c,
876 and BN_mod_mul_reciprocal, which stays in crypto/bn/bn_recp.c)
877 and add new functions:
890 These functions always generate non-negative results.
892 BN_nnmod otherwise is like BN_mod (if BN_mod computes a remainder r
893 such that |m| < r < 0, BN_nnmod will output rem + |m| instead).
895 BN_mod_XXX_quick(r, a, [b,] m) generates the same result as
896 BN_mod_XXX(r, a, [b,] m, ctx), but requires that a [and b]
898 [Lenka Fibikova <fibikova@exp-math.uni-essen.de>, Bodo Moeller]
900 *) Remove a few calls to bn_wexpand() in BN_sqr() (the one in there
901 was actually never needed) and in BN_mul(). The removal in BN_mul()
902 required a small change in bn_mul_part_recursive() and the addition
903 of the functions bn_cmp_part_words(), bn_sub_part_words() and
904 bn_add_part_words(), which do the same thing as bn_cmp_words(),
905 bn_sub_words() and bn_add_words() except they take arrays with
909 *) In 'openssl passwd', verify passwords read from the terminal
910 unless the '-salt' option is used (which usually means that
911 verification would just waste user's time since the resulting
912 hash is going to be compared with some given password hash)
913 or the new '-noverify' option is used.
915 This is an incompatible change, but it does not affect
916 non-interactive use of 'openssl passwd' (passwords on the command
917 line, '-stdin' option, '-in ...' option) and thus should not
921 *) Remove all references to RSAref, since there's no more need for it.
924 *) Increase BN_CTX_NUM (the number of BIGNUMs in a BN_CTX) to 16.
925 The previous value, 12, was not always sufficient for BN_mod_exp().
928 *) Make DSO load along a path given through an environment variable
929 (SHLIB_PATH) with shl_load().
932 *) Constify the ENGINE code as a result of BIGNUM constification.
933 Also constify the RSA code and most things related to it. In a
934 few places, most notable in the depth of the ASN.1 code, ugly
935 casts back to non-const were required (to be solved at a later
939 *) Make it so the openssl application has all engines loaded by default.
942 *) Constify the BIGNUM routines a little more.
945 *) Make sure that shared libraries get the internal name engine with
946 the full version number and not just 0. This should mark the
947 shared libraries as not backward compatible. Of course, this should
948 be changed again when we can guarantee backward binary compatibility.
951 *) Add the following functions:
957 ENGINE_load_builtin_engines()
959 That way, an application can itself choose if external engines that
960 are built-in in OpenSSL shall ever be used or not. The benefit is
961 that applications won't have to be linked with libdl or other dso
962 libraries unless it's really needed.
964 Changed 'openssl engine' to load all engines on demand.
965 Changed the engine header files to avoid the duplication of some
966 declarations (they differed!).
969 *) 'openssl engine' can now list capabilities.
972 *) Better error reporting in 'openssl engine'.
975 *) Never call load_dh_param(NULL) in s_server.
978 *) Add engine application. It can currently list engines by name and
979 identity, and test if they are actually available.
982 *) Add support for shared libraries under Irix.
983 [Albert Chin-A-Young <china@thewrittenword.com>]
985 *) Improve RPM specification file by forcing symbolic linking and making
986 sure the installed documentation is also owned by root.root.
987 [Damien Miller <djm@mindrot.org>]
989 *) Add configuration option to build on Linux on both big-endian and
991 [Ralf Baechle <ralf@uni-koblenz.de>]
993 *) Give the OpenSSL applications more possibilities to make use of
994 keys (public as well as private) handled by engines.
997 *) Add OCSP code that comes from CertCo.
1000 *) Add VMS support for the Rijndael code.
1003 *) Added untested support for Nuron crypto accelerator.
1006 *) Add support for external cryptographic devices. This code was
1007 previously distributed separately as the "engine" branch.
1008 [Geoff Thorpe, Richard Levitte]
1010 *) Rework the filename-translation in the DSO code. It is now possible to
1011 have far greater control over how a "name" is turned into a filename
1012 depending on the operating environment and any oddities about the
1013 different shared library filenames on each system.
1016 *) Support threads on FreeBSD-elf in Configure.
1019 *) Add the possibility to create shared libraries on HP-UX
1022 *) Fix for SHA1 assembly problem with MASM: it produces
1023 warnings about corrupt line number information when assembling
1024 with debugging information. This is caused by the overlapping
1026 [Bernd Matthes <mainbug@celocom.de>, Steve Henson]
1029 NCONF_get_number() has no error checking at all. As a replacement,
1030 NCONF_get_number_e() is defined (_e for "error checking") and is
1031 promoted strongly. The old NCONF_get_number is kept around for
1032 binary backward compatibility.
1033 Make it possible for methods to load from something other than a BIO,
1034 by providing a function pointer that is given a name instead of a BIO.
1035 For example, this could be used to load configuration data from an
1039 *) Fix typo in get_cert_by_subject() in by_dir.c
1040 [Jean-Marc Desperrier <jean-marc.desperrier@certplus.com>]
1042 *) Rework the system to generate shared libraries:
1044 - Make note of the expected extension for the shared libraries and
1045 if there is a need for symbolic links from for example libcrypto.so.0
1046 to libcrypto.so.0.9.7. There is extended info in Configure for
1049 - Make as few rebuilds of the shared libraries as possible.
1051 - Still avoid linking the OpenSSL programs with the shared libraries.
1053 - When installing, install the shared libraries separately from the
1057 *) Fix for non blocking accept BIOs. Added new I/O special reason
1058 BIO_RR_ACCEPT to cover this case. Previously use of accept BIOs
1059 with non blocking I/O was not possible because no retry code was
1060 implemented. Also added new SSL code SSL_WANT_ACCEPT to cover
1064 *) Added the beginnings of Rijndael support.
1067 *) Fix for bug in DirectoryString mask setting. Add support for
1068 X509_NAME_print_ex() in 'req' and X509_print_ex() function
1069 to allow certificate printing to more controllable, additional
1070 'certopt' option to 'x509' to allow new printing options to be
1074 *) Clean old EAY MD5 hack from e_os.h.
1077 *) Fix SSL_CTX_set_read_ahead macro to actually use its argument.
1079 Copy SSL_CTX's read_ahead flag to SSL object directly in SSL_new
1080 and not in SSL_clear because the latter is also used by the
1081 accept/connect functions; previously, the settings made by
1082 SSL_set_read_ahead would be lost during the handshake.
1083 [Bodo Moeller; problems reported by Anders Gertz <gertz@epact.se>]
1085 *) Correct util/mkdef.pl to be selective about disabled algorithms.
1086 Previously, it would create entries for disableed algorithms no
1090 *) Added several new manual pages for SSL_* function.
1093 Changes between 0.9.5a and 0.9.6 [24 Sep 2000]
1095 *) In ssl23_get_client_hello, generate an error message when faced
1096 with an initial SSL 3.0/TLS record that is too small to contain the
1097 first two bytes of the ClientHello message, i.e. client_version.
1098 (Note that this is a pathologic case that probably has never happened
1099 in real life.) The previous approach was to use the version number
1100 from the record header as a substitute; but our protocol choice
1101 should not depend on that one because it is not authenticated
1102 by the Finished messages.
1105 *) More robust randomness gathering functions for Windows.
1106 [Jeffrey Altman <jaltman@columbia.edu>]
1108 *) For compatibility reasons if the flag X509_V_FLAG_ISSUER_CHECK is
1109 not set then we don't setup the error code for issuer check errors
1110 to avoid possibly overwriting other errors which the callback does
1111 handle. If an application does set the flag then we assume it knows
1112 what it is doing and can handle the new informational codes
1116 *) Fix for a nasty bug in ASN1_TYPE handling. ASN1_TYPE is used for
1117 a general "ANY" type, as such it should be able to decode anything
1118 including tagged types. However it didn't check the class so it would
1119 wrongly interpret tagged types in the same way as their universal
1120 counterpart and unknown types were just rejected. Changed so that the
1121 tagged and unknown types are handled in the same way as a SEQUENCE:
1122 that is the encoding is stored intact. There is also a new type
1123 "V_ASN1_OTHER" which is used when the class is not universal, in this
1124 case we have no idea what the actual type is so we just lump them all
1128 *) On VMS, stdout may very well lead to a file that is written to
1129 in a record-oriented fashion. That means that every write() will
1130 write a separate record, which will be read separately by the
1131 programs trying to read from it. This can be very confusing.
1133 The solution is to put a BIO filter in the way that will buffer
1134 text until a linefeed is reached, and then write everything a
1135 line at a time, so every record written will be an actual line,
1136 not chunks of lines and not (usually doesn't happen, but I've
1137 seen it once) several lines in one record. BIO_f_linebuffer() is
1140 Currently, it's a VMS-only method, because that's where it has
1141 been tested well enough.
1144 *) Remove 'optimized' squaring variant in BN_mod_mul_montgomery,
1145 it can return incorrect results.
1146 (Note: The buggy variant was not enabled in OpenSSL 0.9.5a,
1147 but it was in 0.9.6-beta[12].)
1150 *) Disable the check for content being present when verifying detached
1151 signatures in pk7_smime.c. Some versions of Netscape (wrongly)
1152 include zero length content when signing messages.
1155 *) New BIO_shutdown_wr macro, which invokes the BIO_C_SHUTDOWN_WR
1156 BIO_ctrl (for BIO pairs).
1159 *) Add DSO method for VMS.
1162 *) Bug fix: Montgomery multiplication could produce results with the
1166 *) Add RPM specification openssl.spec and modify it to build three
1167 packages. The default package contains applications, application
1168 documentation and run-time libraries. The devel package contains
1169 include files, static libraries and function documentation. The
1170 doc package contains the contents of the doc directory. The original
1171 openssl.spec was provided by Damien Miller <djm@mindrot.org>.
1174 *) Add a large number of documentation files for many SSL routines.
1175 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
1177 *) Add a configuration entry for Sony News 4.
1178 [NAKAJI Hiroyuki <nakaji@tutrp.tut.ac.jp>]
1180 *) Don't set the two most significant bits to one when generating a
1181 random number < q in the DSA library.
1184 *) New SSL API mode 'SSL_MODE_AUTO_RETRY'. This disables the default
1185 behaviour that SSL_read may result in SSL_ERROR_WANT_READ (even if
1186 the underlying transport is blocking) if a handshake took place.
1187 (The default behaviour is needed by applications such as s_client
1188 and s_server that use select() to determine when to use SSL_read;
1189 but for applications that know in advance when to expect data, it
1190 just makes things more complicated.)
1193 *) Add RAND_egd_bytes(), which gives control over the number of bytes read
1197 *) Add a few more EBCDIC conditionals that make `req' and `x509'
1198 work better on such systems.
1199 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
1201 *) Add two demo programs for PKCS12_parse() and PKCS12_create().
1202 Update PKCS12_parse() so it copies the friendlyName and the
1203 keyid to the certificates aux info.
1206 *) Fix bug in PKCS7_verify() which caused an infinite loop
1207 if there was more than one signature.
1208 [Sven Uszpelkat <su@celocom.de>]
1210 *) Major change in util/mkdef.pl to include extra information
1211 about each symbol, as well as presentig variables as well
1212 as functions. This change means that there's n more need
1213 to rebuild the .num files when some algorithms are excluded.
1216 *) Allow the verify time to be set by an application,
1217 rather than always using the current time.
1220 *) Phase 2 verify code reorganisation. The certificate
1221 verify code now looks up an issuer certificate by a
1222 number of criteria: subject name, authority key id
1223 and key usage. It also verifies self signed certificates
1224 by the same criteria. The main comparison function is
1225 X509_check_issued() which performs these checks.
1227 Lot of changes were necessary in order to support this
1228 without completely rewriting the lookup code.
1230 Authority and subject key identifier are now cached.
1232 The LHASH 'certs' is X509_STORE has now been replaced
1233 by a STACK_OF(X509_OBJECT). This is mainly because an
1234 LHASH can't store or retrieve multiple objects with
1235 the same hash value.
1237 As a result various functions (which were all internal
1238 use only) have changed to handle the new X509_STORE
1239 structure. This will break anything that messed round
1240 with X509_STORE internally.
1242 The functions X509_STORE_add_cert() now checks for an
1243 exact match, rather than just subject name.
1245 The X509_STORE API doesn't directly support the retrieval
1246 of multiple certificates matching a given criteria, however
1247 this can be worked round by performing a lookup first
1248 (which will fill the cache with candidate certificates)
1249 and then examining the cache for matches. This is probably
1250 the best we can do without throwing out X509_LOOKUP
1251 entirely (maybe later...).
1253 The X509_VERIFY_CTX structure has been enhanced considerably.
1255 All certificate lookup operations now go via a get_issuer()
1256 callback. Although this currently uses an X509_STORE it
1257 can be replaced by custom lookups. This is a simple way
1258 to bypass the X509_STORE hackery necessary to make this
1259 work and makes it possible to use more efficient techniques
1260 in future. A very simple version which uses a simple
1261 STACK for its trusted certificate store is also provided
1262 using X509_STORE_CTX_trusted_stack().
1264 The verify_cb() and verify() callbacks now have equivalents
1265 in the X509_STORE_CTX structure.
1267 X509_STORE_CTX also has a 'flags' field which can be used
1268 to customise the verify behaviour.
1271 *) Add new PKCS#7 signing option PKCS7_NOSMIMECAP which
1272 excludes S/MIME capabilities.
1275 *) When a certificate request is read in keep a copy of the
1276 original encoding of the signed data and use it when outputing
1277 again. Signatures then use the original encoding rather than
1278 a decoded, encoded version which may cause problems if the
1279 request is improperly encoded.
1282 *) For consistency with other BIO_puts implementations, call
1283 buffer_write(b, ...) directly in buffer_puts instead of calling
1286 In BIO_puts, increment b->num_write as in BIO_write.
1287 [Peter.Sylvester@EdelWeb.fr]
1289 *) Fix BN_mul_word for the case where the word is 0. (We have to use
1290 BN_zero, we may not return a BIGNUM with an array consisting of
1294 *) Avoid calling abort() from within the library when problems are
1295 detected, except if preprocessor symbols have been defined
1296 (such as REF_CHECK, BN_DEBUG etc.).
1299 *) New openssl application 'rsautl'. This utility can be
1300 used for low level RSA operations. DER public key
1301 BIO/fp routines also added.
1304 *) New Configure entry and patches for compiling on QNX 4.
1305 [Andreas Schneider <andreas@ds3.etech.fh-hamburg.de>]
1307 *) A demo state-machine implementation was sponsored by
1308 Nuron (http://www.nuron.com/) and is now available in
1309 demos/state_machine.
1312 *) New options added to the 'dgst' utility for signature
1313 generation and verification.
1316 *) Unrecognized PKCS#7 content types are now handled via a
1317 catch all ASN1_TYPE structure. This allows unsupported
1318 types to be stored as a "blob" and an application can
1319 encode and decode it manually.
1322 *) Fix various signed/unsigned issues to make a_strex.c
1324 [Oscar Jacobsson <oscar.jacobsson@celocom.com>]
1326 *) ASN1 fixes. i2d_ASN1_OBJECT was not returning the correct
1327 length if passed a buffer. ASN1_INTEGER_to_BN failed
1328 if passed a NULL BN and its argument was negative.
1329 [Steve Henson, pointed out by Sven Heiberg <sven@tartu.cyber.ee>]
1331 *) Modification to PKCS#7 encoding routines to output definite
1332 length encoding. Since currently the whole structures are in
1333 memory there's not real point in using indefinite length
1334 constructed encoding. However if OpenSSL is compiled with
1335 the flag PKCS7_INDEFINITE_ENCODING the old form is used.
1338 *) Added BIO_vprintf() and BIO_vsnprintf().
1341 *) Added more prefixes to parse for in the the strings written
1342 through a logging bio, to cover all the levels that are available
1343 through syslog. The prefixes are now:
1345 PANIC, EMERG, EMR => LOG_EMERG
1346 ALERT, ALR => LOG_ALERT
1347 CRIT, CRI => LOG_CRIT
1348 ERROR, ERR => LOG_ERR
1349 WARNING, WARN, WAR => LOG_WARNING
1350 NOTICE, NOTE, NOT => LOG_NOTICE
1351 INFO, INF => LOG_INFO
1352 DEBUG, DBG => LOG_DEBUG
1354 and as before, if none of those prefixes are present at the
1355 beginning of the string, LOG_ERR is chosen.
1357 On Win32, the LOG_* levels are mapped according to this:
1359 LOG_EMERG, LOG_ALERT, LOG_CRIT, LOG_ERR => EVENTLOG_ERROR_TYPE
1360 LOG_WARNING => EVENTLOG_WARNING_TYPE
1361 LOG_NOTICE, LOG_INFO, LOG_DEBUG => EVENTLOG_INFORMATION_TYPE
1365 *) Made it possible to reconfigure with just the configuration
1366 argument "reconf" or "reconfigure". The command line arguments
1367 are stored in Makefile.ssl in the variable CONFIGURE_ARGS,
1368 and are retrieved from there when reconfiguring.
1372 [Assar Westerlund <assar@sics.se>, Richard Levitte]
1374 *) Add the arguments -CAfile and -CApath to the pkcs12 utility.
1377 *) The obj_dat.pl script was messing up the sorting of object
1378 names. The reason was that it compared the quoted version
1379 of strings as a result "OCSP" > "OCSP Signing" because
1380 " > SPACE. Changed script to store unquoted versions of
1381 names and add quotes on output. It was also omitting some
1382 names from the lookup table if they were given a default
1383 value (that is if SN is missing it is given the same
1384 value as LN and vice versa), these are now added on the
1385 grounds that if an object has a name we should be able to
1386 look it up. Finally added warning output when duplicate
1387 short or long names are found.
1390 *) Changes needed for Tandem NSK.
1391 [Scott Uroff <scott@xypro.com>]
1393 *) Fix SSL 2.0 rollback checking: Due to an off-by-one error in
1394 RSA_padding_check_SSLv23(), special padding was never detected
1395 and thus the SSL 3.0/TLS 1.0 countermeasure against protocol
1396 version rollback attacks was not effective.
1398 In s23_clnt.c, don't use special rollback-attack detection padding
1399 (RSA_SSLV23_PADDING) if SSL 2.0 is the only protocol enabled in the
1400 client; similarly, in s23_srvr.c, don't do the rollback check if
1401 SSL 2.0 is the only protocol enabled in the server.
1404 *) Make it possible to get hexdumps of unprintable data with 'openssl
1405 asn1parse'. By implication, the functions ASN1_parse_dump() and
1406 BIO_dump_indent() are added.
1409 *) New functions ASN1_STRING_print_ex() and X509_NAME_print_ex()
1410 these print out strings and name structures based on various
1411 flags including RFC2253 support and proper handling of
1412 multibyte characters. Added options to the 'x509' utility
1413 to allow the various flags to be set.
1416 *) Various fixes to use ASN1_TIME instead of ASN1_UTCTIME.
1417 Also change the functions X509_cmp_current_time() and
1418 X509_gmtime_adj() work with an ASN1_TIME structure,
1419 this will enable certificates using GeneralizedTime in validity
1420 dates to be checked.
1423 *) Make the NEG_PUBKEY_BUG code (which tolerates invalid
1424 negative public key encodings) on by default,
1425 NO_NEG_PUBKEY_BUG can be set to disable it.
1428 *) New function c2i_ASN1_OBJECT() which acts on ASN1_OBJECT
1429 content octets. An i2c_ASN1_OBJECT is unnecessary because
1430 the encoding can be trivially obtained from the structure.
1433 *) crypto/err.c locking bugfix: Use write locks (CRYPTO_w_[un]lock),
1434 not read locks (CRYPTO_r_[un]lock).
1437 *) A first attempt at creating official support for shared
1438 libraries through configuration. I've kept it so the
1439 default is static libraries only, and the OpenSSL programs
1440 are always statically linked for now, but there are
1441 preparations for dynamic linking in place.
1442 This has been tested on Linux and True64.
1445 *) Randomness polling function for Win9x, as described in:
1446 Peter Gutmann, Software Generation of Practically Strong
1450 *) Fix so PRNG is seeded in req if using an already existing
1454 *) New options to smime application. -inform and -outform
1455 allow alternative formats for the S/MIME message including
1456 PEM and DER. The -content option allows the content to be
1457 specified separately. This should allow things like Netscape
1458 form signing output easier to verify.
1461 *) Fix the ASN1 encoding of tags using the 'long form'.
1464 *) New ASN1 functions, i2c_* and c2i_* for INTEGER and BIT
1465 STRING types. These convert content octets to and from the
1466 underlying type. The actual tag and length octets are
1467 already assumed to have been read in and checked. These
1468 are needed because all other string types have virtually
1469 identical handling apart from the tag. By having versions
1470 of the ASN1 functions that just operate on content octets
1471 IMPLICIT tagging can be handled properly. It also allows
1472 the ASN1_ENUMERATED code to be cut down because ASN1_ENUMERATED
1473 and ASN1_INTEGER are identical apart from the tag.
1476 *) Change the handling of OID objects as follows:
1478 - New object identifiers are inserted in objects.txt, following
1479 the syntax given in objects.README.
1480 - objects.pl is used to process obj_mac.num and create a new
1482 - obj_dat.pl is used to create a new obj_dat.h, using the data in
1485 This is currently kind of a hack, and the perl code in objects.pl
1486 isn't very elegant, but it works as I intended. The simplest way
1487 to check that it worked correctly is to look in obj_dat.h and
1488 check the array nid_objs and make sure the objects haven't moved
1489 around (this is important!). Additions are OK, as well as
1490 consistent name changes.
1493 *) Add BSD-style MD5-based passwords to 'openssl passwd' (option '-1').
1496 *) Addition of the command line parameter '-rand file' to 'openssl req'.
1497 The given file adds to whatever has already been seeded into the
1498 random pool through the RANDFILE configuration file option or
1499 environment variable, or the default random state file.
1502 *) mkstack.pl now sorts each macro group into lexical order.
1503 Previously the output order depended on the order the files
1504 appeared in the directory, resulting in needless rewriting
1508 *) Patches to make OpenSSL compile under Win32 again. Mostly
1509 work arounds for the VC++ problem that it treats func() as
1510 func(void). Also stripped out the parts of mkdef.pl that
1511 added extra typesafe functions: these no longer exist.
1514 *) Reorganisation of the stack code. The macros are now all
1515 collected in safestack.h . Each macro is defined in terms of
1516 a "stack macro" of the form SKM_<name>(type, a, b). The
1517 DEBUG_SAFESTACK is now handled in terms of function casts,
1518 this has the advantage of retaining type safety without the
1519 use of additional functions. If DEBUG_SAFESTACK is not defined
1520 then the non typesafe macros are used instead. Also modified the
1521 mkstack.pl script to handle the new form. Needs testing to see
1522 if which (if any) compilers it chokes and maybe make DEBUG_SAFESTACK
1523 the default if no major problems. Similar behaviour for ASN1_SET_OF
1524 and PKCS12_STACK_OF.
1527 *) When some versions of IIS use the 'NET' form of private key the
1528 key derivation algorithm is different. Normally MD5(password) is
1529 used as a 128 bit RC4 key. In the modified case
1530 MD5(MD5(password) + "SGCKEYSALT") is used insted. Added some
1531 new functions i2d_RSA_NET(), d2i_RSA_NET() etc which are the same
1532 as the old Netscape_RSA functions except they have an additional
1533 'sgckey' parameter which uses the modified algorithm. Also added
1534 an -sgckey command line option to the rsa utility. Thanks to
1535 Adrian Peck <bertie@ncipher.com> for posting details of the modified
1536 algorithm to openssl-dev.
1539 *) The evp_local.h macros were using 'c.##kname' which resulted in
1540 invalid expansion on some systems (SCO 5.0.5 for example).
1541 Corrected to 'c.kname'.
1542 [Phillip Porch <root@theporch.com>]
1544 *) New X509_get1_email() and X509_REQ_get1_email() functions that return
1545 a STACK of email addresses from a certificate or request, these look
1546 in the subject name and the subject alternative name extensions and
1547 omit any duplicate addresses.
1550 *) Re-implement BN_mod_exp2_mont using independent (and larger) windows.
1551 This makes DSA verification about 2 % faster.
1554 *) Increase maximum window size in BN_mod_exp_... to 6 bits instead of 5
1555 (meaning that now 2^5 values will be precomputed, which is only 4 KB
1556 plus overhead for 1024 bit moduli).
1557 This makes exponentiations about 0.5 % faster for 1024 bit
1558 exponents (as measured by "openssl speed rsa2048").
1561 *) Rename memory handling macros to avoid conflicts with other
1563 Malloc => OPENSSL_malloc
1564 Malloc_locked => OPENSSL_malloc_locked
1565 Realloc => OPENSSL_realloc
1566 Free => OPENSSL_free
1569 *) New function BN_mod_exp_mont_word for small bases (roughly 15%
1570 faster than BN_mod_exp_mont, i.e. 7% for a full DH exchange).
1573 *) CygWin32 support.
1574 [John Jarvie <jjarvie@newsguy.com>]
1576 *) The type-safe stack code has been rejigged. It is now only compiled
1577 in when OpenSSL is configured with the DEBUG_SAFESTACK option and
1578 by default all type-specific stack functions are "#define"d back to
1579 standard stack functions. This results in more streamlined output
1580 but retains the type-safety checking possibilities of the original
1584 *) The STACK code has been cleaned up, and certain type declarations
1585 that didn't make a lot of sense have been brought in line. This has
1586 also involved a cleanup of sorts in safestack.h to more correctly
1587 map type-safe stack functions onto their plain stack counterparts.
1588 This work has also resulted in a variety of "const"ifications of
1589 lots of the code, especially "_cmp" operations which should normally
1590 be prototyped with "const" parameters anyway.
1593 *) When generating bytes for the first time in md_rand.c, 'stir the pool'
1594 by seeding with STATE_SIZE dummy bytes (with zero entropy count).
1595 (The PRNG state consists of two parts, the large pool 'state' and 'md',
1596 where all of 'md' is used each time the PRNG is used, but 'state'
1597 is used only indexed by a cyclic counter. As entropy may not be
1598 well distributed from the beginning, 'md' is important as a
1599 chaining variable. However, the output function chains only half
1600 of 'md', i.e. 80 bits. ssleay_rand_add, on the other hand, chains
1601 all of 'md', and seeding with STATE_SIZE dummy bytes will result
1602 in all of 'state' being rewritten, with the new values depending
1603 on virtually all of 'md'. This overcomes the 80 bit limitation.)
1606 *) In ssl/s2_clnt.c and ssl/s3_clnt.c, call ERR_clear_error() when
1607 the handshake is continued after ssl_verify_cert_chain();
1608 otherwise, if SSL_VERIFY_NONE is set, remaining error codes
1609 can lead to 'unexplainable' connection aborts later.
1610 [Bodo Moeller; problem tracked down by Lutz Jaenicke]
1612 *) Major EVP API cipher revision.
1613 Add hooks for extra EVP features. This allows various cipher
1614 parameters to be set in the EVP interface. Support added for variable
1615 key length ciphers via the EVP_CIPHER_CTX_set_key_length() function and
1616 setting of RC2 and RC5 parameters.
1618 Modify EVP_OpenInit() and EVP_SealInit() to cope with variable key length
1621 Remove lots of duplicated code from the EVP library. For example *every*
1622 cipher init() function handles the 'iv' in the same way according to the
1623 cipher mode. They also all do nothing if the 'key' parameter is NULL and
1624 for CFB and OFB modes they zero ctx->num.
1626 New functionality allows removal of S/MIME code RC2 hack.
1628 Most of the routines have the same form and so can be declared in terms
1631 By shifting this to the top level EVP_CipherInit() it can be removed from
1632 all individual ciphers. If the cipher wants to handle IVs or keys
1633 differently it can set the EVP_CIPH_CUSTOM_IV or EVP_CIPH_ALWAYS_CALL_INIT
1636 Change lots of functions like EVP_EncryptUpdate() to now return a
1637 value: although software versions of the algorithms cannot fail
1638 any installed hardware versions can.
1641 *) Implement SSL_OP_TLS_ROLLBACK_BUG: In ssl3_get_client_key_exchange, if
1642 this option is set, tolerate broken clients that send the negotiated
1643 protocol version number instead of the requested protocol version
1647 *) Call dh_tmp_cb (set by ..._TMP_DH_CB) with correct 'is_export' flag;
1648 i.e. non-zero for export ciphersuites, zero otherwise.
1649 Previous versions had this flag inverted, inconsistent with
1650 rsa_tmp_cb (..._TMP_RSA_CB).
1651 [Bodo Moeller; problem reported by Amit Chopra]
1653 *) Add missing DSA library text string. Work around for some IIS
1654 key files with invalid SEQUENCE encoding.
1657 *) Add a document (doc/standards.txt) that list all kinds of standards
1658 and so on that are implemented in OpenSSL.
1661 *) Enhance c_rehash script. Old version would mishandle certificates
1662 with the same subject name hash and wouldn't handle CRLs at all.
1663 Added -fingerprint option to crl utility, to support new c_rehash
1667 *) Eliminate non-ANSI declarations in crypto.h and stack.h.
1670 *) Fix for SSL server purpose checking. Server checking was
1671 rejecting certificates which had extended key usage present
1672 but no ssl client purpose.
1673 [Steve Henson, reported by Rene Grosser <grosser@hisolutions.com>]
1675 *) Make PKCS#12 code work with no password. The PKCS#12 spec
1676 is a little unclear about how a blank password is handled.
1677 Since the password in encoded as a BMPString with terminating
1678 double NULL a zero length password would end up as just the
1679 double NULL. However no password at all is different and is
1680 handled differently in the PKCS#12 key generation code. NS
1681 treats a blank password as zero length. MSIE treats it as no
1682 password on export: but it will try both on import. We now do
1683 the same: PKCS12_parse() tries zero length and no password if
1684 the password is set to "" or NULL (NULL is now a valid password:
1685 it wasn't before) as does the pkcs12 application.
1688 *) Bugfixes in apps/x509.c: Avoid a memory leak; and don't use
1689 perror when PEM_read_bio_X509_REQ fails, the error message must
1690 be obtained from the error queue.
1693 *) Avoid 'thread_hash' memory leak in crypto/err/err.c by freeing
1694 it in ERR_remove_state if appropriate, and change ERR_get_state
1695 accordingly to avoid race conditions (this is necessary because
1696 thread_hash is no longer constant once set).
1699 *) Bugfix for linux-elf makefile.one.
1702 *) RSA_get_default_method() will now cause a default
1703 RSA_METHOD to be chosen if one doesn't exist already.
1704 Previously this was only set during a call to RSA_new()
1705 or RSA_new_method(NULL) meaning it was possible for
1706 RSA_get_default_method() to return NULL.
1709 *) Added native name translation to the existing DSO code
1710 that will convert (if the flag to do so is set) filenames
1711 that are sufficiently small and have no path information
1712 into a canonical native form. Eg. "blah" converted to
1713 "libblah.so" or "blah.dll" etc.
1716 *) New function ERR_error_string_n(e, buf, len) which is like
1717 ERR_error_string(e, buf), but writes at most 'len' bytes
1718 including the 0 terminator. For ERR_error_string_n, 'buf'
1720 [Damien Miller <djm@mindrot.org>, Bodo Moeller]
1722 *) CONF library reworked to become more general. A new CONF
1723 configuration file reader "class" is implemented as well as a
1724 new functions (NCONF_*, for "New CONF") to handle it. The now
1725 old CONF_* functions are still there, but are reimplemented to
1726 work in terms of the new functions. Also, a set of functions
1727 to handle the internal storage of the configuration data is
1728 provided to make it easier to write new configuration file
1729 reader "classes" (I can definitely see something reading a
1730 configuration file in XML format, for example), called _CONF_*,
1731 or "the configuration storage API"...
1733 The new configuration file reading functions are:
1735 NCONF_new, NCONF_free, NCONF_load, NCONF_load_fp, NCONF_load_bio,
1736 NCONF_get_section, NCONF_get_string, NCONF_get_numbre
1738 NCONF_default, NCONF_WIN32
1740 NCONF_dump_fp, NCONF_dump_bio
1742 NCONF_default and NCONF_WIN32 are method (or "class") choosers,
1743 NCONF_new creates a new CONF object. This works in the same way
1744 as other interfaces in OpenSSL, like the BIO interface.
1745 NCONF_dump_* dump the internal storage of the configuration file,
1746 which is useful for debugging. All other functions take the same
1747 arguments as the old CONF_* functions wth the exception of the
1748 first that must be a `CONF *' instead of a `LHASH *'.
1750 To make it easer to use the new classes with the old CONF_* functions,
1751 the function CONF_set_default_method is provided.
1754 *) Add '-tls1' option to 'openssl ciphers', which was already
1755 mentioned in the documentation but had not been implemented.
1756 (This option is not yet really useful because even the additional
1757 experimental TLS 1.0 ciphers are currently treated as SSL 3.0 ciphers.)
1760 *) Initial DSO code added into libcrypto for letting OpenSSL (and
1761 OpenSSL-based applications) load shared libraries and bind to
1762 them in a portable way.
1763 [Geoff Thorpe, with contributions from Richard Levitte]
1765 Changes between 0.9.5 and 0.9.5a [1 Apr 2000]
1767 *) Make sure _lrotl and _lrotr are only used with MSVC.
1769 *) Use lock CRYPTO_LOCK_RAND correctly in ssleay_rand_status
1770 (the default implementation of RAND_status).
1772 *) Rename openssl x509 option '-crlext', which was added in 0.9.5,
1773 to '-clrext' (= clear extensions), as intended and documented.
1774 [Bodo Moeller; inconsistency pointed out by Michael Attili
1777 *) Fix for HMAC. It wasn't zeroing the rest of the block if the key length
1778 was larger than the MD block size.
1779 [Steve Henson, pointed out by Yost William <YostW@tce.com>]
1781 *) Modernise PKCS12_parse() so it uses STACK_OF(X509) for its ca argument
1782 fix a leak when the ca argument was passed as NULL. Stop X509_PUBKEY_set()
1783 using the passed key: if the passed key was a private key the result
1784 of X509_print(), for example, would be to print out all the private key
1788 *) des_quad_cksum() byte order bug fix.
1789 [Ulf Möller, using the problem description in krb4-0.9.7, where
1790 the solution is attributed to Derrick J Brashear <shadow@DEMENTIA.ORG>]
1792 *) Fix so V_ASN1_APP_CHOOSE works again: however its use is strongly
1794 [Steve Henson, pointed out by Brian Korver <briank@cs.stanford.edu>]
1796 *) For easily testing in shell scripts whether some command
1797 'openssl XXX' exists, the new pseudo-command 'openssl no-XXX'
1798 returns with exit code 0 iff no command of the given name is available.
1799 'no-XXX' is printed in this case, 'XXX' otherwise. In both cases,
1800 the output goes to stdout and nothing is printed to stderr.
1801 Additional arguments are always ignored.
1803 Since for each cipher there is a command of the same name,
1804 the 'no-cipher' compilation switches can be tested this way.
1806 ('openssl no-XXX' is not able to detect pseudo-commands such
1807 as 'quit', 'list-XXX-commands', or 'no-XXX' itself.)
1810 *) Update test suite so that 'make test' succeeds in 'no-rsa' configuration.
1813 *) For SSL_[CTX_]set_tmp_dh, don't create a DH key if SSL_OP_SINGLE_DH_USE
1814 is set; it will be thrown away anyway because each handshake creates
1816 ssl_cert_dup, which is used by SSL_new, now copies DH keys in addition
1817 to parameters -- in previous versions (since OpenSSL 0.9.3) the
1818 'default key' from SSL_CTX_set_tmp_dh would always be lost, meanining
1819 you effectivly got SSL_OP_SINGLE_DH_USE when using this macro.
1822 *) New s_client option -ign_eof: EOF at stdin is ignored, and
1823 'Q' and 'R' lose their special meanings (quit/renegotiate).
1824 This is part of what -quiet does; unlike -quiet, -ign_eof
1825 does not suppress any output.
1828 *) Add compatibility options to the purpose and trust code. The
1829 purpose X509_PURPOSE_ANY is "any purpose" which automatically
1830 accepts a certificate or CA, this was the previous behaviour,
1831 with all the associated security issues.
1833 X509_TRUST_COMPAT is the old trust behaviour: only and
1834 automatically trust self signed roots in certificate store. A
1835 new trust setting X509_TRUST_DEFAULT is used to specify that
1836 a purpose has no associated trust setting and it should instead
1837 use the value in the default purpose.
1840 *) Fix the PKCS#8 DSA private key code so it decodes keys again
1841 and fix a memory leak.
1844 *) In util/mkerr.pl (which implements 'make errors'), preserve
1845 reason strings from the previous version of the .c file, as
1846 the default to have only downcase letters (and digits) in
1847 automatically generated reasons codes is not always appropriate.
1850 *) In ERR_load_ERR_strings(), build an ERR_LIB_SYS error reason table
1851 using strerror. Previously, ERR_reason_error_string() returned
1852 library names as reason strings for SYSerr; but SYSerr is a special
1853 case where small numbers are errno values, not library numbers.
1856 *) Add '-dsaparam' option to 'openssl dhparam' application. This
1857 converts DSA parameters into DH parameters. (When creating parameters,
1858 DSA_generate_parameters is used.)
1861 *) Include 'length' (recommended exponent length) in C code generated
1862 by 'openssl dhparam -C'.
1865 *) The second argument to set_label in perlasm was already being used
1866 so couldn't be used as a "file scope" flag. Moved to third argument
1870 *) In PEM_ASN1_write_bio and some other functions, use RAND_pseudo_bytes
1871 instead of RAND_bytes for encryption IVs and salts.
1874 *) Include RAND_status() into RAND_METHOD instead of implementing
1875 it only for md_rand.c Otherwise replacing the PRNG by calling
1876 RAND_set_rand_method would be impossible.
1879 *) Don't let DSA_generate_key() enter an infinite loop if the random
1880 number generation fails.
1883 *) New 'rand' application for creating pseudo-random output.
1886 *) Added configuration support for Linux/IA64
1887 [Rolf Haberrecker <rolf@suse.de>]
1889 *) Assembler module support for Mingw32.
1892 *) Shared library support for HPUX (in shlib/).
1893 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE> and Anonymous]
1895 *) Shared library support for Solaris gcc.
1896 [Lutz Behnke <behnke@trustcenter.de>]
1898 Changes between 0.9.4 and 0.9.5 [28 Feb 2000]
1900 *) PKCS7_encrypt() was adding text MIME headers twice because they
1901 were added manually and by SMIME_crlf_copy().
1904 *) In bntest.c don't call BN_rand with zero bits argument.
1905 [Steve Henson, pointed out by Andrew W. Gray <agray@iconsinc.com>]
1907 *) BN_mul bugfix: In bn_mul_part_recursion() only the a>a[n] && b>b[n]
1908 case was implemented. This caused BN_div_recp() to fail occasionally.
1911 *) Add an optional second argument to the set_label() in the perl
1912 assembly language builder. If this argument exists and is set
1913 to 1 it signals that the assembler should use a symbol whose
1914 scope is the entire file, not just the current function. This
1915 is needed with MASM which uses the format label:: for this scope.
1916 [Steve Henson, pointed out by Peter Runestig <peter@runestig.com>]
1918 *) Change the ASN1 types so they are typedefs by default. Before
1919 almost all types were #define'd to ASN1_STRING which was causing
1920 STACK_OF() problems: you couldn't declare STACK_OF(ASN1_UTF8STRING)
1924 *) Change names of new functions to the new get1/get0 naming
1925 convention: After 'get1', the caller owns a reference count
1926 and has to call ..._free; 'get0' returns a pointer to some
1927 data structure without incrementing reference counters.
1928 (Some of the existing 'get' functions increment a reference
1929 counter, some don't.)
1930 Similarly, 'set1' and 'add1' functions increase reference
1931 counters or duplicate objects.
1934 *) Allow for the possibility of temp RSA key generation failure:
1935 the code used to assume it always worked and crashed on failure.
1938 *) Fix potential buffer overrun problem in BIO_printf().
1939 [Ulf Möller, using public domain code by Patrick Powell; problem
1940 pointed out by David Sacerdote <das33@cornell.edu>]
1942 *) Support EGD <http://www.lothar.com/tech/crypto/>. New functions
1943 RAND_egd() and RAND_status(). In the command line application,
1944 the EGD socket can be specified like a seed file using RANDFILE
1948 *) Allow the string CERTIFICATE to be tolerated in PKCS#7 structures.
1949 Some CAs (e.g. Verisign) distribute certificates in this form.
1952 *) Remove the SSL_ALLOW_ADH compile option and set the default cipher
1953 list to exclude them. This means that no special compilation option
1954 is needed to use anonymous DH: it just needs to be included in the
1958 *) Change the EVP_MD_CTX_type macro so its meaning consistent with
1959 EVP_MD_type. The old functionality is available in a new macro called
1960 EVP_MD_md(). Change code that uses it and update docs.
1963 *) ..._ctrl functions now have corresponding ..._callback_ctrl functions
1964 where the 'void *' argument is replaced by a function pointer argument.
1965 Previously 'void *' was abused to point to functions, which works on
1966 many platforms, but is not correct. As these functions are usually
1967 called by macros defined in OpenSSL header files, most source code
1968 should work without changes.
1971 *) <openssl/opensslconf.h> (which is created by Configure) now contains
1972 sections with information on -D... compiler switches used for
1973 compiling the library so that applications can see them. To enable
1974 one of these sections, a pre-processor symbol OPENSSL_..._DEFINES
1975 must be defined. E.g.,
1976 #define OPENSSL_ALGORITHM_DEFINES
1977 #include <openssl/opensslconf.h>
1978 defines all pertinent NO_<algo> symbols, such as NO_IDEA, NO_RSA, etc.
1979 [Richard Levitte, Ulf and Bodo Möller]
1981 *) Bugfix: Tolerate fragmentation and interleaving in the SSL 3/TLS
1985 *) Change the 'other' type in certificate aux info to a STACK_OF
1986 X509_ALGOR. Although not an AlgorithmIdentifier as such it has
1987 the required ASN1 format: arbitrary types determined by an OID.
1990 *) Add some PEM_write_X509_REQ_NEW() functions and a command line
1991 argument to 'req'. This is not because the function is newer or
1992 better than others it just uses the work 'NEW' in the certificate
1993 request header lines. Some software needs this.
1996 *) Reorganise password command line arguments: now passwords can be
1997 obtained from various sources. Delete the PEM_cb function and make
1998 it the default behaviour: i.e. if the callback is NULL and the
1999 usrdata argument is not NULL interpret it as a null terminated pass
2000 phrase. If usrdata and the callback are NULL then the pass phrase
2001 is prompted for as usual.
2004 *) Add support for the Compaq Atalla crypto accelerator. If it is installed,
2005 the support is automatically enabled. The resulting binaries will
2006 autodetect the card and use it if present.
2007 [Ben Laurie and Compaq Inc.]
2009 *) Work around for Netscape hang bug. This sends certificate request
2010 and server done in one record. Since this is perfectly legal in the
2011 SSL/TLS protocol it isn't a "bug" option and is on by default. See
2012 the bugs/SSLv3 entry for more info.
2015 *) HP-UX tune-up: new unified configs, HP C compiler bug workaround.
2018 *) Add -rand argument to smime and pkcs12 applications and read/write
2022 *) New 'passwd' tool for crypt(3) and apr1 password hashes.
2025 *) Add command line password options to the remaining applications.
2028 *) Bug fix for BN_div_recp() for numerators with an even number of
2032 *) More tests in bntest.c, and changed test_bn output.
2035 *) ./config recognizes MacOS X now.
2038 *) Bug fix for BN_div() when the first words of num and divsor are
2039 equal (it gave wrong results if (rem=(n1-q*d0)&BN_MASK2) < d0).
2042 *) Add support for various broken PKCS#8 formats, and command line
2043 options to produce them.
2046 *) New functions BN_CTX_start(), BN_CTX_get() and BT_CTX_end() to
2047 get temporary BIGNUMs from a BN_CTX.
2050 *) Correct return values in BN_mod_exp_mont() and BN_mod_exp2_mont()
2054 *) Change the SSLeay_add_all_*() functions to OpenSSL_add_all_*() and
2055 include a #define from the old name to the new. The original intent
2056 was that statically linked binaries could for example just call
2057 SSLeay_add_all_ciphers() to just add ciphers to the table and not
2058 link with digests. This never worked becayse SSLeay_add_all_digests()
2059 and SSLeay_add_all_ciphers() were in the same source file so calling
2060 one would link with the other. They are now in separate source files.
2063 *) Add a new -notext option to 'ca' and a -pubkey option to 'spkac'.
2066 *) Use a less unusual form of the Miller-Rabin primality test (it used
2067 a binary algorithm for exponentiation integrated into the Miller-Rabin
2068 loop, our standard modexp algorithms are faster).
2071 *) Support for the EBCDIC character set completed.
2072 [Martin Kraemer <Martin.Kraemer@Mch.SNI.De>]
2074 *) Source code cleanups: use const where appropriate, eliminate casts,
2075 use void * instead of char * in lhash.
2078 *) Bugfix: ssl3_send_server_key_exchange was not restartable
2079 (the state was not changed to SSL3_ST_SW_KEY_EXCH_B, and because of
2080 this the server could overwrite ephemeral keys that the client
2084 *) Turn DSA_is_prime into a macro that calls BN_is_prime,
2085 using 50 iterations of the Rabin-Miller test.
2087 DSA_generate_parameters now uses BN_is_prime_fasttest (with 50
2088 iterations of the Rabin-Miller test as required by the appendix
2089 to FIPS PUB 186[-1]) instead of DSA_is_prime.
2090 As BN_is_prime_fasttest includes trial division, DSA parameter
2091 generation becomes much faster.
2093 This implies a change for the callback functions in DSA_is_prime
2094 and DSA_generate_parameters: The callback function is called once
2095 for each positive witness in the Rabin-Miller test, not just
2096 occasionally in the inner loop; and the parameters to the
2097 callback function now provide an iteration count for the outer
2098 loop rather than for the current invocation of the inner loop.
2099 DSA_generate_parameters additionally can call the callback
2100 function with an 'iteration count' of -1, meaning that a
2101 candidate has passed the trial division test (when q is generated
2102 from an application-provided seed, trial division is skipped).
2105 *) New function BN_is_prime_fasttest that optionally does trial
2106 division before starting the Rabin-Miller test and has
2107 an additional BN_CTX * argument (whereas BN_is_prime always
2108 has to allocate at least one BN_CTX).
2109 'callback(1, -1, cb_arg)' is called when a number has passed the
2110 trial division stage.
2113 *) Fix for bug in CRL encoding. The validity dates weren't being handled
2117 *) New -pkcs12 option to CA.pl script to write out a PKCS#12 file.
2120 *) New function BN_pseudo_rand().
2123 *) Clean up BN_mod_mul_montgomery(): replace the broken (and unreadable)
2124 bignum version of BN_from_montgomery() with the working code from
2125 SSLeay 0.9.0 (the word based version is faster anyway), and clean up
2129 *) Avoid a race condition in s2_clnt.c (function get_server_hello) that
2130 made it impossible to use the same SSL_SESSION data structure in
2131 SSL2 clients in multiple threads.
2134 *) The return value of RAND_load_file() no longer counts bytes obtained
2135 by stat(). RAND_load_file(..., -1) is new and uses the complete file
2136 to seed the PRNG (previously an explicit byte count was required).
2137 [Ulf Möller, Bodo Möller]
2139 *) Clean up CRYPTO_EX_DATA functions, some of these didn't have prototypes
2140 used (char *) instead of (void *) and had casts all over the place.
2143 *) Make BN_generate_prime() return NULL on error if ret!=NULL.
2146 *) Retain source code compatibility for BN_prime_checks macro:
2147 BN_is_prime(..., BN_prime_checks, ...) now uses
2148 BN_prime_checks_for_size to determine the appropriate number of
2149 Rabin-Miller iterations.
2152 *) Diffie-Hellman uses "safe" primes: DH_check() return code renamed to
2153 DH_CHECK_P_NOT_SAFE_PRIME.
2154 (Check if this is true? OpenPGP calls them "strong".)
2157 *) Merge the functionality of "dh" and "gendh" programs into a new program
2158 "dhparam". The old programs are retained for now but will handle DH keys
2159 (instead of parameters) in future.
2162 *) Make the ciphers, s_server and s_client programs check the return values
2163 when a new cipher list is set.
2166 *) Enhance the SSL/TLS cipher mechanism to correctly handle the TLS 56bit
2167 ciphers. Before when the 56bit ciphers were enabled the sorting was
2170 The syntax for the cipher sorting has been extended to support sorting by
2171 cipher-strength (using the strength_bits hard coded in the tables).
2172 The new command is "@STRENGTH" (see also doc/apps/ciphers.pod).
2174 Fix a bug in the cipher-command parser: when supplying a cipher command
2175 string with an "undefined" symbol (neither command nor alphanumeric
2176 [A-Za-z0-9], ssl_set_cipher_list used to hang in an endless loop. Now
2177 an error is flagged.
2179 Due to the strength-sorting extension, the code of the
2180 ssl_create_cipher_list() function was completely rearranged. I hope that
2181 the readability was also increased :-)
2182 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
2184 *) Minor change to 'x509' utility. The -CAcreateserial option now uses 1
2185 for the first serial number and places 2 in the serial number file. This
2186 avoids problems when the root CA is created with serial number zero and
2187 the first user certificate has the same issuer name and serial number
2191 *) Fixes to X509_ATTRIBUTE utilities, change the 'req' program so it uses
2192 the new code. Add documentation for this stuff.
2195 *) Changes to X509_ATTRIBUTE utilities. These have been renamed from
2196 X509_*() to X509at_*() on the grounds that they don't handle X509
2197 structures and behave in an analagous way to the X509v3 functions:
2198 they shouldn't be called directly but wrapper functions should be used
2201 So we also now have some wrapper functions that call the X509at functions
2202 when passed certificate requests. (TO DO: similar things can be done with
2203 PKCS#7 signed and unsigned attributes, PKCS#12 attributes and a few other
2204 things. Some of these need some d2i or i2d and print functionality
2205 because they handle more complex structures.)
2208 *) Add missing #ifndefs that caused missing symbols when building libssl
2209 as a shared library without RSA. Use #ifndef NO_SSL2 instead of
2210 NO_RSA in ssl/s2*.c.
2211 [Kris Kennaway <kris@hub.freebsd.org>, modified by Ulf Möller]
2213 *) Precautions against using the PRNG uninitialized: RAND_bytes() now
2214 has a return value which indicates the quality of the random data
2215 (1 = ok, 0 = not seeded). Also an error is recorded on the thread's
2216 error queue. New function RAND_pseudo_bytes() generates output that is
2217 guaranteed to be unique but not unpredictable. RAND_add is like
2218 RAND_seed, but takes an extra argument for an entropy estimate
2219 (RAND_seed always assumes full entropy).
2222 *) Do more iterations of Rabin-Miller probable prime test (specifically,
2223 3 for 1024-bit primes, 6 for 512-bit primes, 12 for 256-bit primes
2224 instead of only 2 for all lengths; see BN_prime_checks_for_size definition
2225 in crypto/bn/bn_prime.c for the complete table). This guarantees a
2226 false-positive rate of at most 2^-80 for random input.
2229 *) Rewrite ssl3_read_n (ssl/s3_pkt.c) avoiding a couple of bugs.
2232 *) New function X509_CTX_rget_chain() (renamed to X509_CTX_get1_chain
2233 in the 0.9.5 release), this returns the chain
2234 from an X509_CTX structure with a dup of the stack and all
2235 the X509 reference counts upped: so the stack will exist
2236 after X509_CTX_cleanup() has been called. Modify pkcs12.c
2239 Also make SSL_SESSION_print() print out the verify return
2243 *) Add manpage for the pkcs12 command. Also change the default
2244 behaviour so MAC iteration counts are used unless the new
2245 -nomaciter option is used. This improves file security and
2246 only older versions of MSIE (4.0 for example) need it.
2249 *) Honor the no-xxx Configure options when creating .DEF files.
2252 *) Add PKCS#10 attributes to field table: challengePassword,
2253 unstructuredName and unstructuredAddress. These are taken from
2254 draft PKCS#9 v2.0 but are compatible with v1.2 provided no
2255 international characters are used.
2257 More changes to X509_ATTRIBUTE code: allow the setting of types
2258 based on strings. Remove the 'loc' parameter when adding
2259 attributes because these will be a SET OF encoding which is sorted
2263 *) Initial changes to the 'req' utility to allow request generation
2264 automation. This will allow an application to just generate a template
2265 file containing all the field values and have req construct the
2268 Initial support for X509_ATTRIBUTE handling. Stacks of these are
2269 used all over the place including certificate requests and PKCS#7
2270 structures. They are currently handled manually where necessary with
2271 some primitive wrappers for PKCS#7. The new functions behave in a
2272 manner analogous to the X509 extension functions: they allow
2273 attributes to be looked up by NID and added.
2275 Later something similar to the X509V3 code would be desirable to
2276 automatically handle the encoding, decoding and printing of the
2277 more complex types. The string types like challengePassword can
2278 be handled by the string table functions.
2280 Also modified the multi byte string table handling. Now there is
2281 a 'global mask' which masks out certain types. The table itself
2282 can use the flag STABLE_NO_MASK to ignore the mask setting: this
2283 is useful when for example there is only one permissible type
2284 (as in countryName) and using the mask might result in no valid
2288 *) Clean up 'Finished' handling, and add functions SSL_get_finished and
2289 SSL_get_peer_finished to allow applications to obtain the latest
2290 Finished messages sent to the peer or expected from the peer,
2291 respectively. (SSL_get_peer_finished is usually the Finished message
2292 actually received from the peer, otherwise the protocol will be aborted.)
2294 As the Finished message are message digests of the complete handshake
2295 (with a total of 192 bits for TLS 1.0 and more for SSL 3.0), they can
2296 be used for external authentication procedures when the authentication
2297 provided by SSL/TLS is not desired or is not enough.
2300 *) Enhanced support for Alpha Linux is added. Now ./config checks if
2301 the host supports BWX extension and if Compaq C is present on the
2302 $PATH. Just exploiting of the BWX extension results in 20-30%
2303 performance kick for some algorithms, e.g. DES and RC4 to mention
2304 a couple. Compaq C in turn generates ~20% faster code for MD5 and
2308 *) Add support for MS "fast SGC". This is arguably a violation of the
2309 SSL3/TLS protocol. Netscape SGC does two handshakes: the first with
2310 weak crypto and after checking the certificate is SGC a second one
2311 with strong crypto. MS SGC stops the first handshake after receiving
2312 the server certificate message and sends a second client hello. Since
2313 a server will typically do all the time consuming operations before
2314 expecting any further messages from the client (server key exchange
2315 is the most expensive) there is little difference between the two.
2317 To get OpenSSL to support MS SGC we have to permit a second client
2318 hello message after we have sent server done. In addition we have to
2319 reset the MAC if we do get this second client hello.
2322 *) Add a function 'd2i_AutoPrivateKey()' this will automatically decide
2323 if a DER encoded private key is RSA or DSA traditional format. Changed
2324 d2i_PrivateKey_bio() to use it. This is only needed for the "traditional"
2325 format DER encoded private key. Newer code should use PKCS#8 format which
2326 has the key type encoded in the ASN1 structure. Added DER private key
2327 support to pkcs8 application.
2330 *) SSL 3/TLS 1 servers now don't request certificates when an anonymous
2331 ciphersuites has been selected (as required by the SSL 3/TLS 1
2332 specifications). Exception: When SSL_VERIFY_FAIL_IF_NO_PEER_CERT
2333 is set, we interpret this as a request to violate the specification
2334 (the worst that can happen is a handshake failure, and 'correct'
2335 behaviour would result in a handshake failure anyway).
2338 *) In SSL_CTX_add_session, take into account that there might be multiple
2339 SSL_SESSION structures with the same session ID (e.g. when two threads
2340 concurrently obtain them from an external cache).
2341 The internal cache can handle only one SSL_SESSION with a given ID,
2342 so if there's a conflict, we now throw out the old one to achieve
2346 *) Add OIDs for idea and blowfish in CBC mode. This will allow both
2347 to be used in PKCS#5 v2.0 and S/MIME. Also add checking to
2348 some routines that use cipher OIDs: some ciphers do not have OIDs
2349 defined and so they cannot be used for S/MIME and PKCS#5 v2.0 for
2353 *) Simplify the trust setting structure and code. Now we just have
2354 two sequences of OIDs for trusted and rejected settings. These will
2355 typically have values the same as the extended key usage extension
2356 and any application specific purposes.
2358 The trust checking code now has a default behaviour: it will just
2359 check for an object with the same NID as the passed id. Functions can
2360 be provided to override either the default behaviour or the behaviour
2361 for a given id. SSL client, server and email already have functions
2362 in place for compatibility: they check the NID and also return "trusted"
2363 if the certificate is self signed.
2366 *) Add d2i,i2d bio/fp functions for PrivateKey: these convert the
2367 traditional format into an EVP_PKEY structure.
2370 *) Add a password callback function PEM_cb() which either prompts for
2371 a password if usr_data is NULL or otherwise assumes it is a null
2372 terminated password. Allow passwords to be passed on command line
2373 environment or config files in a few more utilities.
2376 *) Add a bunch of DER and PEM functions to handle PKCS#8 format private
2377 keys. Add some short names for PKCS#8 PBE algorithms and allow them
2378 to be specified on the command line for the pkcs8 and pkcs12 utilities.
2379 Update documentation.
2382 *) Support for ASN1 "NULL" type. This could be handled before by using
2383 ASN1_TYPE but there wasn't any function that would try to read a NULL
2384 and produce an error if it couldn't. For compatibility we also have
2385 ASN1_NULL_new() and ASN1_NULL_free() functions but these are faked and
2386 don't allocate anything because they don't need to.
2389 *) Initial support for MacOS is now provided. Examine INSTALL.MacOS
2391 [Andy Polyakov, Roy Woods <roy@centicsystems.ca>]
2393 *) Rebuild of the memory allocation routines used by OpenSSL code and
2394 possibly others as well. The purpose is to make an interface that
2395 provide hooks so anyone can build a separate set of allocation and
2396 deallocation routines to be used by OpenSSL, for example memory
2397 pool implementations, or something else, which was previously hard
2398 since Malloc(), Realloc() and Free() were defined as macros having
2399 the values malloc, realloc and free, respectively (except for Win32
2400 compilations). The same is provided for memory debugging code.
2401 OpenSSL already comes with functionality to find memory leaks, but
2402 this gives people a chance to debug other memory problems.
2404 With these changes, a new set of functions and macros have appeared:
2406 CRYPTO_set_mem_debug_functions() [F]
2407 CRYPTO_get_mem_debug_functions() [F]
2408 CRYPTO_dbg_set_options() [F]
2409 CRYPTO_dbg_get_options() [F]
2410 CRYPTO_malloc_debug_init() [M]
2412 The memory debug functions are NULL by default, unless the library
2413 is compiled with CRYPTO_MDEBUG or friends is defined. If someone
2414 wants to debug memory anyway, CRYPTO_malloc_debug_init() (which
2415 gives the standard debugging functions that come with OpenSSL) or
2416 CRYPTO_set_mem_debug_functions() (tells OpenSSL to use functions
2417 provided by the library user) must be used. When the standard
2418 debugging functions are used, CRYPTO_dbg_set_options can be used to
2419 request additional information:
2420 CRYPTO_dbg_set_options(V_CYRPTO_MDEBUG_xxx) corresponds to setting
2421 the CRYPTO_MDEBUG_xxx macro when compiling the library.
2423 Also, things like CRYPTO_set_mem_functions will always give the
2424 expected result (the new set of functions is used for allocation
2425 and deallocation) at all times, regardless of platform and compiler
2428 To finish it up, some functions that were never use in any other
2429 way than through macros have a new API and new semantic:
2432 CRYPTO_dbg_realloc()
2435 All macros of value have retained their old syntax.
2436 [Richard Levitte and Bodo Moeller]
2438 *) Some S/MIME fixes. The OID for SMIMECapabilities was wrong, the
2439 ordering of SMIMECapabilities wasn't in "strength order" and there
2440 was a missing NULL in the AlgorithmIdentifier for the SHA1 signature
2444 *) Some ASN1 types with illegal zero length encoding (INTEGER,
2445 ENUMERATED and OBJECT IDENTIFIER) choked the ASN1 routines.
2446 [Frans Heymans <fheymans@isaserver.be>, modified by Steve Henson]
2448 *) Merge in my S/MIME library for OpenSSL. This provides a simple
2449 S/MIME API on top of the PKCS#7 code, a MIME parser (with enough
2450 functionality to handle multipart/signed properly) and a utility
2451 called 'smime' to call all this stuff. This is based on code I
2452 originally wrote for Celo who have kindly allowed it to be
2453 included in OpenSSL.
2456 *) Add variants des_set_key_checked and des_set_key_unchecked of
2457 des_set_key (aka des_key_sched). Global variable des_check_key
2458 decides which of these is called by des_set_key; this way
2459 des_check_key behaves as it always did, but applications and
2460 the library itself, which was buggy for des_check_key == 1,
2461 have a cleaner way to pick the version they need.
2464 *) New function PKCS12_newpass() which changes the password of a
2468 *) Modify X509_TRUST and X509_PURPOSE so it also uses a static and
2469 dynamic mix. In both cases the ids can be used as an index into the
2470 table. Also modified the X509_TRUST_add() and X509_PURPOSE_add()
2471 functions so they accept a list of the field values and the
2472 application doesn't need to directly manipulate the X509_TRUST
2476 *) Modify the ASN1_STRING_TABLE stuff so it also uses bsearch and doesn't
2480 *) Modify the way the V3 extension code looks up extensions. This now
2481 works in a similar way to the object code: we have some "standard"
2482 extensions in a static table which is searched with OBJ_bsearch()
2483 and the application can add dynamic ones if needed. The file
2484 crypto/x509v3/ext_dat.h now has the info: this file needs to be
2485 updated whenever a new extension is added to the core code and kept
2486 in ext_nid order. There is a simple program 'tabtest.c' which checks
2487 this. New extensions are not added too often so this file can readily
2488 be maintained manually.
2490 There are two big advantages in doing things this way. The extensions
2491 can be looked up immediately and no longer need to be "added" using
2492 X509V3_add_standard_extensions(): this function now does nothing.
2493 [Side note: I get *lots* of email saying the extension code doesn't
2494 work because people forget to call this function]
2495 Also no dynamic allocation is done unless new extensions are added:
2496 so if we don't add custom extensions there is no need to call
2497 X509V3_EXT_cleanup().
2500 *) Modify enc utility's salting as follows: make salting the default. Add a
2501 magic header, so unsalted files fail gracefully instead of just decrypting
2502 to garbage. This is because not salting is a big security hole, so people
2503 should be discouraged from doing it.
2506 *) Fixes and enhancements to the 'x509' utility. It allowed a message
2507 digest to be passed on the command line but it only used this
2508 parameter when signing a certificate. Modified so all relevant
2509 operations are affected by the digest parameter including the
2510 -fingerprint and -x509toreq options. Also -x509toreq choked if a
2511 DSA key was used because it didn't fix the digest.
2514 *) Initial certificate chain verify code. Currently tests the untrusted
2515 certificates for consistency with the verify purpose (which is set
2516 when the X509_STORE_CTX structure is set up) and checks the pathlength.
2518 There is a NO_CHAIN_VERIFY compilation option to keep the old behaviour:
2519 this is because it will reject chains with invalid extensions whereas
2520 every previous version of OpenSSL and SSLeay made no checks at all.
2522 Trust code: checks the root CA for the relevant trust settings. Trust
2523 settings have an initial value consistent with the verify purpose: e.g.
2524 if the verify purpose is for SSL client use it expects the CA to be
2525 trusted for SSL client use. However the default value can be changed to
2526 permit custom trust settings: one example of this would be to only trust
2527 certificates from a specific "secure" set of CAs.
2529 Also added X509_STORE_CTX_new() and X509_STORE_CTX_free() functions
2530 which should be used for version portability: especially since the
2531 verify structure is likely to change more often now.
2533 SSL integration. Add purpose and trust to SSL_CTX and SSL and functions
2534 to set them. If not set then assume SSL clients will verify SSL servers
2537 Two new options to the verify program: -untrusted allows a set of
2538 untrusted certificates to be passed in and -purpose which sets the
2539 intended purpose of the certificate. If a purpose is set then the
2540 new chain verify code is used to check extension consistency.
2543 *) Support for the authority information access extension.
2546 *) Modify RSA and DSA PEM read routines to transparently handle
2547 PKCS#8 format private keys. New *_PUBKEY_* functions that handle
2548 public keys in a format compatible with certificate
2549 SubjectPublicKeyInfo structures. Unfortunately there were already
2550 functions called *_PublicKey_* which used various odd formats so
2551 these are retained for compatibility: however the DSA variants were
2552 never in a public release so they have been deleted. Changed dsa/rsa
2553 utilities to handle the new format: note no releases ever handled public
2554 keys so we should be OK.
2556 The primary motivation for this change is to avoid the same fiasco
2557 that dogs private keys: there are several incompatible private key
2558 formats some of which are standard and some OpenSSL specific and
2559 require various evil hacks to allow partial transparent handling and
2560 even then it doesn't work with DER formats. Given the option anything
2561 other than PKCS#8 should be dumped: but the other formats have to
2562 stay in the name of compatibility.
2564 With public keys and the benefit of hindsight one standard format
2565 is used which works with EVP_PKEY, RSA or DSA structures: though
2566 it clearly returns an error if you try to read the wrong kind of key.
2568 Added a -pubkey option to the 'x509' utility to output the public key.
2569 Also rename the EVP_PKEY_get_*() to EVP_PKEY_rget_*()
2570 (renamed to EVP_PKEY_get1_*() in the OpenSSL 0.9.5 release) and add
2571 EVP_PKEY_rset_*() functions (renamed to EVP_PKEY_set1_*())
2572 that do the same as the EVP_PKEY_assign_*() except they up the
2573 reference count of the added key (they don't "swallow" the
2577 *) Fixes to crypto/x509/by_file.c the code to read in certificates and
2578 CRLs would fail if the file contained no certificates or no CRLs:
2579 added a new function to read in both types and return the number
2580 read: this means that if none are read it will be an error. The
2581 DER versions of the certificate and CRL reader would always fail
2582 because it isn't possible to mix certificates and CRLs in DER format
2583 without choking one or the other routine. Changed this to just read
2584 a certificate: this is the best we can do. Also modified the code
2585 in apps/verify.c to take notice of return codes: it was previously
2586 attempting to read in certificates from NULL pointers and ignoring
2587 any errors: this is one reason why the cert and CRL reader seemed
2588 to work. It doesn't check return codes from the default certificate
2589 routines: these may well fail if the certificates aren't installed.
2592 *) Code to support otherName option in GeneralName.
2595 *) First update to verify code. Change the verify utility
2596 so it warns if it is passed a self signed certificate:
2597 for consistency with the normal behaviour. X509_verify
2598 has been modified to it will now verify a self signed
2599 certificate if *exactly* the same certificate appears
2600 in the store: it was previously impossible to trust a
2601 single self signed certificate. This means that:
2602 openssl verify ss.pem
2603 now gives a warning about a self signed certificate but
2604 openssl verify -CAfile ss.pem ss.pem
2608 *) For servers, store verify_result in SSL_SESSION data structure
2609 (and add it to external session representation).
2610 This is needed when client certificate verifications fails,
2611 but an application-provided verification callback (set by
2612 SSL_CTX_set_cert_verify_callback) allows accepting the session
2613 anyway (i.e. leaves x509_store_ctx->error != X509_V_OK
2614 but returns 1): When the session is reused, we have to set
2615 ssl->verify_result to the appropriate error code to avoid
2617 [Bodo Moeller, problem pointed out by Lutz Jaenicke]
2619 *) Fix a bug in the new PKCS#7 code: it didn't consider the
2620 case in PKCS7_dataInit() where the signed PKCS7 structure
2621 didn't contain any existing data because it was being created.
2622 [Po-Cheng Chen <pocheng@nst.com.tw>, slightly modified by Steve Henson]
2624 *) Add a salt to the key derivation routines in enc.c. This
2625 forms the first 8 bytes of the encrypted file. Also add a
2626 -S option to allow a salt to be input on the command line.
2629 *) New function X509_cmp(). Oddly enough there wasn't a function
2630 to compare two certificates. We do this by working out the SHA1
2631 hash and comparing that. X509_cmp() will be needed by the trust
2635 *) SSL_get1_session() is like SSL_get_session(), but increments
2636 the reference count in the SSL_SESSION returned.
2637 [Geoff Thorpe <geoff@eu.c2.net>]
2639 *) Fix for 'req': it was adding a null to request attributes.
2640 Also change the X509_LOOKUP and X509_INFO code to handle
2641 certificate auxiliary information.
2644 *) Add support for 40 and 64 bit RC2 and RC4 algorithms: document
2648 *) Add the possibility to add extra information to the memory leak
2649 detecting output, to form tracebacks, showing from where each
2650 allocation was originated: CRYPTO_push_info("constant string") adds
2651 the string plus current file name and line number to a per-thread
2652 stack, CRYPTO_pop_info() does the obvious, CRYPTO_remove_all_info()
2653 is like calling CYRPTO_pop_info() until the stack is empty.
2654 Also updated memory leak detection code to be multi-thread-safe.
2657 *) Add options -text and -noout to pkcs7 utility and delete the
2658 encryption options which never did anything. Update docs.
2661 *) Add options to some of the utilities to allow the pass phrase
2662 to be included on either the command line (not recommended on
2663 OSes like Unix) or read from the environment. Update the
2664 manpages and fix a few bugs.
2667 *) Add a few manpages for some of the openssl commands.
2670 *) Fix the -revoke option in ca. It was freeing up memory twice,
2671 leaking and not finding already revoked certificates.
2674 *) Extensive changes to support certificate auxiliary information.
2675 This involves the use of X509_CERT_AUX structure and X509_AUX
2676 functions. An X509_AUX function such as PEM_read_X509_AUX()
2677 can still read in a certificate file in the usual way but it
2678 will also read in any additional "auxiliary information". By
2679 doing things this way a fair degree of compatibility can be
2680 retained: existing certificates can have this information added
2681 using the new 'x509' options.
2683 Current auxiliary information includes an "alias" and some trust
2684 settings. The trust settings will ultimately be used in enhanced
2685 certificate chain verification routines: currently a certificate
2686 can only be trusted if it is self signed and then it is trusted
2690 *) Fix assembler for Alpha (tested only on DEC OSF not Linux or *BSD).
2691 The problem was that one of the replacement routines had not been working
2692 since SSLeay releases. For now the offending routine has been replaced
2693 with non-optimised assembler. Even so, this now gives around 95%
2694 performance improvement for 1024 bit RSA signs.
2697 *) Hack to fix PKCS#7 decryption when used with some unorthodox RC2
2698 handling. Most clients have the effective key size in bits equal to
2699 the key length in bits: so a 40 bit RC2 key uses a 40 bit (5 byte) key.
2700 A few however don't do this and instead use the size of the decrypted key
2701 to determine the RC2 key length and the AlgorithmIdentifier to determine
2702 the effective key length. In this case the effective key length can still
2703 be 40 bits but the key length can be 168 bits for example. This is fixed
2704 by manually forcing an RC2 key into the EVP_PKEY structure because the
2705 EVP code can't currently handle unusual RC2 key sizes: it always assumes
2706 the key length and effective key length are equal.
2709 *) Add a bunch of functions that should simplify the creation of
2710 X509_NAME structures. Now you should be able to do:
2711 X509_NAME_add_entry_by_txt(nm, "CN", MBSTRING_ASC, "Steve", -1, -1, 0);
2712 and have it automatically work out the correct field type and fill in
2713 the structures. The more adventurous can try:
2714 X509_NAME_add_entry_by_txt(nm, field, MBSTRING_UTF8, str, -1, -1, 0);
2715 and it will (hopefully) work out the correct multibyte encoding.
2718 *) Change the 'req' utility to use the new field handling and multibyte
2719 copy routines. Before the DN field creation was handled in an ad hoc
2720 way in req, ca, and x509 which was rather broken and didn't support
2721 BMPStrings or UTF8Strings. Since some software doesn't implement
2722 BMPStrings or UTF8Strings yet, they can be enabled using the config file
2723 using the dirstring_type option. See the new comment in the default
2724 openssl.cnf for more info.
2727 *) Make crypto/rand/md_rand.c more robust:
2728 - Assure unique random numbers after fork().
2729 - Make sure that concurrent threads access the global counter and
2730 md serializably so that we never lose entropy in them
2731 or use exactly the same state in multiple threads.
2732 Access to the large state is not always serializable because
2733 the additional locking could be a performance killer, and
2734 md should be large enough anyway.
2737 *) New file apps/app_rand.c with commonly needed functionality
2738 for handling the random seed file.
2740 Use the random seed file in some applications that previously did not:
2742 dsaparam -genkey (which also ignored its '-rand' option),
2745 x509 (when signing).
2746 Except on systems with /dev/urandom, it is crucial to have a random
2747 seed file at least for key creation, DSA signing, and for DH exchanges;
2748 for RSA signatures we could do without one.
2750 gendh and gendsa (unlike genrsa) used to read only the first byte
2751 of each file listed in the '-rand' option. The function as previously
2752 found in genrsa is now in app_rand.c and is used by all programs
2753 that support '-rand'.
2756 *) In RAND_write_file, use mode 0600 for creating files;
2757 don't just chmod when it may be too late.
2760 *) Report an error from X509_STORE_load_locations
2761 when X509_LOOKUP_load_file or X509_LOOKUP_add_dir failed.
2764 *) New function ASN1_mbstring_copy() this copies a string in either
2765 ASCII, Unicode, Universal (4 bytes per character) or UTF8 format
2766 into an ASN1_STRING type. A mask of permissible types is passed
2767 and it chooses the "minimal" type to use or an error if not type
2771 *) Add function equivalents to the various macros in asn1.h. The old
2772 macros are retained with an M_ prefix. Code inside the library can
2773 use the M_ macros. External code (including the openssl utility)
2774 should *NOT* in order to be "shared library friendly".
2777 *) Add various functions that can check a certificate's extensions
2778 to see if it usable for various purposes such as SSL client,
2779 server or S/MIME and CAs of these types. This is currently
2780 VERY EXPERIMENTAL but will ultimately be used for certificate chain
2781 verification. Also added a -purpose flag to x509 utility to
2782 print out all the purposes.
2785 *) Add a CRYPTO_EX_DATA to X509 certificate structure and associated
2789 *) New X509V3_{X509,CRL,REVOKED}_get_d2i() functions. These will search
2790 for, obtain and decode and extension and obtain its critical flag.
2791 This allows all the necessary extension code to be handled in a
2792 single function call.
2795 *) RC4 tune-up featuring 30-40% performance improvement on most RISC
2796 platforms. See crypto/rc4/rc4_enc.c for further details.
2799 *) New -noout option to asn1parse. This causes no output to be produced
2800 its main use is when combined with -strparse and -out to extract data
2801 from a file (which may not be in ASN.1 format).
2804 *) Fix for pkcs12 program. It was hashing an invalid certificate pointer
2805 when producing the local key id.
2806 [Richard Levitte <levitte@stacken.kth.se>]
2808 *) New option -dhparam in s_server. This allows a DH parameter file to be
2809 stated explicitly. If it is not stated then it tries the first server
2810 certificate file. The previous behaviour hard coded the filename
2814 *) Add -pubin and -pubout options to the rsa and dsa commands. These allow
2815 a public key to be input or output. For example:
2816 openssl rsa -in key.pem -pubout -out pubkey.pem
2817 Also added necessary DSA public key functions to handle this.
2820 *) Fix so PKCS7_dataVerify() doesn't crash if no certificates are contained
2821 in the message. This was handled by allowing
2822 X509_find_by_issuer_and_serial() to tolerate a NULL passed to it.
2823 [Steve Henson, reported by Sampo Kellomaki <sampo@mail.neuronio.pt>]
2825 *) Fix for bug in d2i_ASN1_bytes(): other ASN1 functions add an extra null
2826 to the end of the strings whereas this didn't. This would cause problems
2827 if strings read with d2i_ASN1_bytes() were later modified.
2828 [Steve Henson, reported by Arne Ansper <arne@ats.cyber.ee>]
2830 *) Fix for base64 decode bug. When a base64 bio reads only one line of
2831 data and it contains EOF it will end up returning an error. This is
2832 caused by input 46 bytes long. The cause is due to the way base64
2833 BIOs find the start of base64 encoded data. They do this by trying a
2834 trial decode on each line until they find one that works. When they
2835 do a flag is set and it starts again knowing it can pass all the
2836 data directly through the decoder. Unfortunately it doesn't reset
2837 the context it uses. This means that if EOF is reached an attempt
2838 is made to pass two EOFs through the context and this causes the
2839 resulting error. This can also cause other problems as well. As is
2840 usual with these problems it takes *ages* to find and the fix is
2841 trivial: move one line.
2842 [Steve Henson, reported by ian@uns.ns.ac.yu (Ivan Nejgebauer) ]
2844 *) Ugly workaround to get s_client and s_server working under Windows. The
2845 old code wouldn't work because it needed to select() on sockets and the
2846 tty (for keypresses and to see if data could be written). Win32 only
2847 supports select() on sockets so we select() with a 1s timeout on the
2848 sockets and then see if any characters are waiting to be read, if none
2849 are present then we retry, we also assume we can always write data to
2850 the tty. This isn't nice because the code then blocks until we've
2851 received a complete line of data and it is effectively polling the
2852 keyboard at 1s intervals: however it's quite a bit better than not
2853 working at all :-) A dedicated Windows application might handle this
2854 with an event loop for example.
2857 *) Enhance RSA_METHOD structure. Now there are two extra methods, rsa_sign
2858 and rsa_verify. When the RSA_FLAGS_SIGN_VER option is set these functions
2859 will be called when RSA_sign() and RSA_verify() are used. This is useful
2860 if rsa_pub_dec() and rsa_priv_enc() equivalents are not available.
2861 For this to work properly RSA_public_decrypt() and RSA_private_encrypt()
2862 should *not* be used: RSA_sign() and RSA_verify() must be used instead.
2863 This necessitated the support of an extra signature type NID_md5_sha1
2864 for SSL signatures and modifications to the SSL library to use it instead
2865 of calling RSA_public_decrypt() and RSA_private_encrypt().
2868 *) Add new -verify -CAfile and -CApath options to the crl program, these
2869 will lookup a CRL issuers certificate and verify the signature in a
2870 similar way to the verify program. Tidy up the crl program so it
2871 no longer accesses structures directly. Make the ASN1 CRL parsing a bit
2872 less strict. It will now permit CRL extensions even if it is not
2873 a V2 CRL: this will allow it to tolerate some broken CRLs.
2876 *) Initialize all non-automatic variables each time one of the openssl
2877 sub-programs is started (this is necessary as they may be started
2878 multiple times from the "OpenSSL>" prompt).
2879 [Lennart Bang, Bodo Moeller]
2881 *) Preliminary compilation option RSA_NULL which disables RSA crypto without
2882 removing all other RSA functionality (this is what NO_RSA does). This
2883 is so (for example) those in the US can disable those operations covered
2884 by the RSA patent while allowing storage and parsing of RSA keys and RSA
2888 *) Non-copying interface to BIO pairs.
2889 (still largely untested)
2892 *) New function ANS1_tag2str() to convert an ASN1 tag to a descriptive
2893 ASCII string. This was handled independently in various places before.
2896 *) New functions UTF8_getc() and UTF8_putc() that parse and generate
2897 UTF8 strings a character at a time.
2900 *) Use client_version from client hello to select the protocol
2901 (s23_srvr.c) and for RSA client key exchange verification
2902 (s3_srvr.c), as required by the SSL 3.0/TLS 1.0 specifications.
2905 *) Add various utility functions to handle SPKACs, these were previously
2906 handled by poking round in the structure internals. Added new function
2907 NETSCAPE_SPKI_print() to print out SPKAC and a new utility 'spkac' to
2908 print, verify and generate SPKACs. Based on an original idea from
2909 Massimiliano Pala <madwolf@comune.modena.it> but extensively modified.
2912 *) RIPEMD160 is operational on all platforms and is back in 'make test'.
2915 *) Allow the config file extension section to be overwritten on the
2916 command line. Based on an original idea from Massimiliano Pala
2917 <madwolf@comune.modena.it>. The new option is called -extensions
2918 and can be applied to ca, req and x509. Also -reqexts to override
2919 the request extensions in req and -crlexts to override the crl extensions
2923 *) Add new feature to the SPKAC handling in ca. Now you can include
2924 the same field multiple times by preceding it by "XXXX." for example:
2927 this is the same syntax as used in the req config file.
2930 *) Allow certificate extensions to be added to certificate requests. These
2931 are specified in a 'req_extensions' option of the req section of the
2932 config file. They can be printed out with the -text option to req but
2933 are otherwise ignored at present.
2936 *) Fix a horrible bug in enc_read() in crypto/evp/bio_enc.c: if the first
2937 data read consists of only the final block it would not decrypted because
2938 EVP_CipherUpdate() would correctly report zero bytes had been decrypted.
2939 A misplaced 'break' also meant the decrypted final block might not be
2940 copied until the next read.
2943 *) Initial support for DH_METHOD. Again based on RSA_METHOD. Also added
2944 a few extra parameters to the DH structure: these will be useful if
2945 for example we want the value of 'q' or implement X9.42 DH.
2948 *) Initial support for DSA_METHOD. This is based on the RSA_METHOD and
2949 provides hooks that allow the default DSA functions or functions on a
2950 "per key" basis to be replaced. This allows hardware acceleration and
2951 hardware key storage to be handled without major modification to the
2952 library. Also added low level modexp hooks and CRYPTO_EX structure and
2953 associated functions.
2956 *) Add a new flag to memory BIOs, BIO_FLAG_MEM_RDONLY. This marks the BIO
2957 as "read only": it can't be written to and the buffer it points to will
2958 not be freed. Reading from a read only BIO is much more efficient than
2959 a normal memory BIO. This was added because there are several times when
2960 an area of memory needs to be read from a BIO. The previous method was
2961 to create a memory BIO and write the data to it, this results in two
2962 copies of the data and an O(n^2) reading algorithm. There is a new
2963 function BIO_new_mem_buf() which creates a read only memory BIO from
2964 an area of memory. Also modified the PKCS#7 routines to use read only
2968 *) Bugfix: ssl23_get_client_hello did not work properly when called in
2969 state SSL23_ST_SR_CLNT_HELLO_B, i.e. when the first 7 bytes of
2970 a SSLv2-compatible client hello for SSLv3 or TLSv1 could be read,
2971 but a retry condition occured while trying to read the rest.
2974 *) The PKCS7_ENC_CONTENT_new() function was setting the content type as
2975 NID_pkcs7_encrypted by default: this was wrong since this should almost
2976 always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle
2977 the encrypted data type: this is a more sensible place to put it and it
2978 allows the PKCS#12 code to be tidied up that duplicated this
2982 *) Changed obj_dat.pl script so it takes its input and output files on
2983 the command line. This should avoid shell escape redirection problems
2987 *) Initial support for certificate extension requests, these are included
2988 in things like Xenroll certificate requests. Included functions to allow
2989 extensions to be obtained and added.
2992 *) -crlf option to s_client and s_server for sending newlines as
2993 CRLF (as required by many protocols).
2996 Changes between 0.9.3a and 0.9.4 [09 Aug 1999]
2998 *) Install libRSAglue.a when OpenSSL is built with RSAref.
2999 [Ralf S. Engelschall]
3001 *) A few more ``#ifndef NO_FP_API / #endif'' pairs for consistency.
3002 [Andrija Antonijevic <TheAntony2@bigfoot.com>]
3004 *) Fix -startdate and -enddate (which was missing) arguments to 'ca'
3008 *) New function DSA_dup_DH, which duplicates DSA parameters/keys as
3009 DH parameters/keys (q is lost during that conversion, but the resulting
3010 DH parameters contain its length).
3012 For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is
3013 much faster than DH_generate_parameters (which creates parameters
3014 where p = 2*q + 1), and also the smaller q makes DH computations
3015 much more efficient (160-bit exponentiation instead of 1024-bit
3016 exponentiation); so this provides a convenient way to support DHE
3017 ciphersuites in SSL/TLS servers (see ssl/ssltest.c). It is of
3018 utter importance to use
3019 SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
3021 SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
3022 when such DH parameters are used, because otherwise small subgroup
3023 attacks may become possible!
3026 *) Avoid memory leak in i2d_DHparams.
3029 *) Allow the -k option to be used more than once in the enc program:
3030 this allows the same encrypted message to be read by multiple recipients.
3033 *) New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts
3034 an ASN1_OBJECT to a text string. If the "no_name" parameter is set then
3035 it will always use the numerical form of the OID, even if it has a short
3039 *) Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp
3040 method only got called if p,q,dmp1,dmq1,iqmp components were present,
3041 otherwise bn_mod_exp was called. In the case of hardware keys for example
3042 no private key components need be present and it might store extra data
3043 in the RSA structure, which cannot be accessed from bn_mod_exp.
3044 By setting RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for
3045 private key operations.
3048 *) Added support for SPARC Linux.
3051 *) pem_password_cb function type incompatibly changed from
3052 typedef int pem_password_cb(char *buf, int size, int rwflag);
3054 ....(char *buf, int size, int rwflag, void *userdata);
3055 so that applications can pass data to their callbacks:
3056 The PEM[_ASN1]_{read,write}... functions and macros now take an
3057 additional void * argument, which is just handed through whenever
3058 the password callback is called.
3059 [Damien Miller <dmiller@ilogic.com.au>; tiny changes by Bodo Moeller]
3061 New function SSL_CTX_set_default_passwd_cb_userdata.
3063 Compatibility note: As many C implementations push function arguments
3064 onto the stack in reverse order, the new library version is likely to
3065 interoperate with programs that have been compiled with the old
3066 pem_password_cb definition (PEM_whatever takes some data that
3067 happens to be on the stack as its last argument, and the callback
3068 just ignores this garbage); but there is no guarantee whatsoever that
3071 *) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=...
3072 (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused
3073 problems not only on Windows, but also on some Unix platforms.
3074 To avoid problematic command lines, these definitions are now in an
3075 auto-generated file crypto/buildinf.h (created by crypto/Makefile.ssl
3076 for standard "make" builds, by util/mk1mf.pl for "mk1mf" builds).
3079 *) MIPS III/IV assembler module is reimplemented.
3082 *) More DES library cleanups: remove references to srand/rand and
3083 delete an unused file.
3086 *) Add support for the the free Netwide assembler (NASM) under Win32,
3087 since not many people have MASM (ml) and it can be hard to obtain.
3088 This is currently experimental but it seems to work OK and pass all
3089 the tests. Check out INSTALL.W32 for info.
3092 *) Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections
3093 without temporary keys kept an extra copy of the server key,
3094 and connections with temporary keys did not free everything in case
3098 *) New function RSA_check_key and new openssl rsa option -check
3099 for verifying the consistency of RSA keys.
3100 [Ulf Moeller, Bodo Moeller]
3102 *) Various changes to make Win32 compile work:
3103 1. Casts to avoid "loss of data" warnings in p5_crpt2.c
3104 2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned
3105 comparison" warnings.
3106 3. Add sk_<TYPE>_sort to DEF file generator and do make update.
3109 *) Add a debugging option to PKCS#5 v2 key generation function: when
3110 you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and
3111 derived keys are printed to stderr.
3114 *) Copy the flags in ASN1_STRING_dup().
3115 [Roman E. Pavlov <pre@mo.msk.ru>]
3117 *) The x509 application mishandled signing requests containing DSA
3118 keys when the signing key was also DSA and the parameters didn't match.
3120 It was supposed to omit the parameters when they matched the signing key:
3121 the verifying software was then supposed to automatically use the CA's
3122 parameters if they were absent from the end user certificate.
3124 Omitting parameters is no longer recommended. The test was also
3125 the wrong way round! This was probably due to unusual behaviour in
3126 EVP_cmp_parameters() which returns 1 if the parameters match.
3127 This meant that parameters were omitted when they *didn't* match and
3128 the certificate was useless. Certificates signed with 'ca' didn't have
3130 [Steve Henson, reported by Doug Erickson <Doug.Erickson@Part.NET>]
3132 *) Memory leak checking (-DCRYPTO_MDEBUG) had some problems.
3133 The interface is as follows:
3134 Applications can use
3135 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(),
3136 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop();
3137 "off" is now the default.
3138 The library internally uses
3139 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(),
3140 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on()
3141 to disable memory-checking temporarily.
3143 Some inconsistent states that previously were possible (and were
3144 even the default) are now avoided.
3146 -DCRYPTO_MDEBUG_TIME is new and additionally stores the current time
3147 with each memory chunk allocated; this is occasionally more helpful
3148 than just having a counter.
3150 -DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID.
3152 -DCRYPTO_MDEBUG_ALL enables all of the above, plus any future
3156 *) Introduce "mode" for SSL structures (with defaults in SSL_CTX),
3157 which largely parallels "options", but is for changing API behaviour,
3158 whereas "options" are about protocol behaviour.
3159 Initial "mode" flags are:
3161 SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when
3162 a single record has been written.
3163 SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write
3164 retries use the same buffer location.
3165 (But all of the contents must be
3169 *) Bugfix: SSL_set_mode ignored its parameter, only SSL_CTX_set_mode
3172 *) Fix problems with no-hmac etc.
3173 [Ulf Möller, pointed out by Brian Wellington <bwelling@tislabs.com>]
3175 *) New functions RSA_get_default_method(), RSA_set_method() and
3176 RSA_get_method(). These allows replacement of RSA_METHODs without having
3177 to mess around with the internals of an RSA structure.
3180 *) Fix memory leaks in DSA_do_sign and DSA_is_prime.
3181 Also really enable memory leak checks in openssl.c and in some
3183 [Chad C. Mulligan, Bodo Moeller]
3185 *) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess
3186 up the length of negative integers. This has now been simplified to just
3187 store the length when it is first determined and use it later, rather
3188 than trying to keep track of where data is copied and updating it to
3190 [Steve Henson, reported by Brien Wheeler
3191 <bwheeler@authentica-security.com>]
3193 *) Add a new function PKCS7_signatureVerify. This allows the verification
3194 of a PKCS#7 signature but with the signing certificate passed to the
3195 function itself. This contrasts with PKCS7_dataVerify which assumes the
3196 certificate is present in the PKCS#7 structure. This isn't always the
3197 case: certificates can be omitted from a PKCS#7 structure and be
3198 distributed by "out of band" means (such as a certificate database).
3201 *) Complete the PEM_* macros with DECLARE_PEM versions to replace the
3202 function prototypes in pem.h, also change util/mkdef.pl to add the
3203 necessary function names.
3206 *) mk1mf.pl (used by Windows builds) did not properly read the
3207 options set by Configure in the top level Makefile, and Configure
3208 was not even able to write more than one option correctly.
3209 Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended.
3212 *) New functions CONF_load_bio() and CONF_load_fp() to allow a config
3213 file to be loaded from a BIO or FILE pointer. The BIO version will
3214 for example allow memory BIOs to contain config info.
3217 *) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS.
3218 Whoever hopes to achieve shared-library compatibility across versions
3219 must use this, not the compile-time macro.
3220 (Exercise 0.9.4: Which is the minimum library version required by
3222 Note: All this applies only to multi-threaded programs, others don't
3226 *) Add missing case to s3_clnt.c state machine -- one of the new SSL tests
3227 through a BIO pair triggered the default case, i.e.
3228 SSLerr(...,SSL_R_UNKNOWN_STATE).
3231 *) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications
3232 can use the SSL library even if none of the specific BIOs is
3236 *) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value
3237 for the encoded length.
3238 [Jeon KyoungHo <khjeon@sds.samsung.co.kr>]
3240 *) Add initial documentation of the X509V3 functions.
3243 *) Add a new pair of functions PEM_write_PKCS8PrivateKey() and
3244 PEM_write_bio_PKCS8PrivateKey() that are equivalent to
3245 PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more
3246 secure PKCS#8 private key format with a high iteration count.
3249 *) Fix determination of Perl interpreter: A perl or perl5
3250 _directory_ in $PATH was also accepted as the interpreter.
3251 [Ralf S. Engelschall]
3253 *) Fix demos/sign/sign.c: well there wasn't anything strictly speaking
3254 wrong with it but it was very old and did things like calling
3255 PEM_ASN1_read() directly and used MD5 for the hash not to mention some
3259 *) Fix demos/selfsign.c: it used obsolete and deleted functions, changed
3260 to use the new extension code.
3263 *) Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c
3264 with macros. This should make it easier to change their form, add extra
3265 arguments etc. Fix a few PEM prototypes which didn't have cipher as a
3269 *) Add to configuration table a new entry that can specify an alternative
3270 name for unistd.h (for pre-POSIX systems); we need this for NeXTstep,
3271 according to Mark Crispin <MRC@Panda.COM>.
3275 *) DES CBC did not update the IV. Weird.
3278 des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does.
3279 Changing the behaviour of the former might break existing programs --
3280 where IV updating is needed, des_ncbc_encrypt can be used.
3283 *) When bntest is run from "make test" it drives bc to check its
3284 calculations, as well as internally checking them. If an internal check
3285 fails, it needs to cause bc to give a non-zero result or make test carries
3286 on without noticing the failure. Fixed.
3289 *) DES library cleanups.
3292 *) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be
3293 used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit
3294 ciphers. NOTE: although the key derivation function has been verified
3295 against some published test vectors it has not been extensively tested
3296 yet. Added a -v2 "cipher" option to pkcs8 application to allow the use
3300 *) Instead of "mkdir -p", which is not fully portable, use new
3301 Perl script "util/mkdir-p.pl".
3304 *) Rewrite the way password based encryption (PBE) is handled. It used to
3305 assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter
3306 structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms
3307 but doesn't apply to PKCS#5 v2.0 where it can be something else. Now
3308 the 'parameter' field of the AlgorithmIdentifier is passed to the
3309 underlying key generation function so it must do its own ASN1 parsing.
3310 This has also changed the EVP_PBE_CipherInit() function which now has a
3311 'parameter' argument instead of literal salt and iteration count values
3312 and the function EVP_PBE_ALGOR_CipherInit() has been deleted.
3315 *) Support for PKCS#5 v1.5 compatible password based encryption algorithms
3316 and PKCS#8 functionality. New 'pkcs8' application linked to openssl.
3317 Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE
3318 KEY" because this clashed with PKCS#8 unencrypted string. Since this
3319 value was just used as a "magic string" and not used directly its
3320 value doesn't matter.
3323 *) Introduce some semblance of const correctness to BN. Shame C doesn't
3327 *) "linux-sparc64" configuration (ultrapenguin).
3328 [Ray Miller <ray.miller@oucs.ox.ac.uk>]
3329 "linux-sparc" configuration.
3330 [Christian Forster <fo@hawo.stw.uni-erlangen.de>]
3332 *) config now generates no-xxx options for missing ciphers.
3335 *) Support the EBCDIC character set (work in progress).
3336 File ebcdic.c not yet included because it has a different license.
3337 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
3339 *) Support BS2000/OSD-POSIX.
3340 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
3342 *) Make callbacks for key generation use void * instead of char *.
3345 *) Make S/MIME samples compile (not yet tested).
3348 *) Additional typesafe stacks.
3351 *) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x).
3355 Changes between 0.9.3 and 0.9.3a [29 May 1999]
3357 *) New configuration variant "sco5-gcc".
3359 *) Updated some demos.
3360 [Sean O Riordain, Wade Scholine]
3362 *) Add missing BIO_free at exit of pkcs12 application.
3365 *) Fix memory leak in conf.c.
3368 *) Updates for Win32 to assembler version of MD5.
3371 *) Set #! path to perl in apps/der_chop to where we found it
3372 instead of using a fixed path.
3375 *) SHA library changes for irix64-mips4-cc.
3378 *) Improvements for VMS support.
3382 Changes between 0.9.2b and 0.9.3 [24 May 1999]
3384 *) Bignum library bug fix. IRIX 6 passes "make test" now!
3385 This also avoids the problems with SC4.2 and unpatched SC5.
3386 [Andy Polyakov <appro@fy.chalmers.se>]
3388 *) New functions sk_num, sk_value and sk_set to replace the previous macros.
3389 These are required because of the typesafe stack would otherwise break
3390 existing code. If old code used a structure member which used to be STACK
3391 and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with
3392 sk_num or sk_value it would produce an error because the num, data members
3393 are not present in STACK_OF. Now it just produces a warning. sk_set
3394 replaces the old method of assigning a value to sk_value
3395 (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code
3396 that does this will no longer work (and should use sk_set instead) but
3397 this could be regarded as a "questionable" behaviour anyway.
3400 *) Fix most of the other PKCS#7 bugs. The "experimental" code can now
3401 correctly handle encrypted S/MIME data.
3404 *) Change type of various DES function arguments from des_cblock
3405 (which means, in function argument declarations, pointer to char)
3406 to des_cblock * (meaning pointer to array with 8 char elements),
3407 which allows the compiler to do more typechecking; it was like
3408 that back in SSLeay, but with lots of ugly casts.
3410 Introduce new type const_des_cblock.
3413 *) Reorganise the PKCS#7 library and get rid of some of the more obvious
3414 problems: find RecipientInfo structure that matches recipient certificate
3415 and initialise the ASN1 structures properly based on passed cipher.
3418 *) Belatedly make the BN tests actually check the results.
3421 *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion
3422 to and from BNs: it was completely broken. New compilation option
3423 NEG_PUBKEY_BUG to allow for some broken certificates that encode public
3424 key elements as negative integers.
3427 *) Reorganize and speed up MD5.
3428 [Andy Polyakov <appro@fy.chalmers.se>]
3431 [Richard Levitte <richard@levitte.org>]
3433 *) New option -out to asn1parse to allow the parsed structure to be
3434 output to a file. This is most useful when combined with the -strparse
3435 option to examine the output of things like OCTET STRINGS.
3438 *) Make SSL library a little more fool-proof by not requiring any longer
3439 that SSL_set_{accept,connect}_state be called before
3440 SSL_{accept,connect} may be used (SSL_set_..._state is omitted
3441 in many applications because usually everything *appeared* to work as
3442 intended anyway -- now it really works as intended).
3445 *) Move openssl.cnf out of lib/.
3448 *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall
3449 -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
3450 -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+
3451 [Ralf S. Engelschall]
3453 *) Various fixes to the EVP and PKCS#7 code. It may now be able to
3454 handle PKCS#7 enveloped data properly.
3455 [Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve]
3457 *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
3458 copying pointers. The cert_st handling is changed by this in
3459 various ways (and thus what used to be known as ctx->default_cert
3460 is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
3461 any longer when s->cert does not give us what we need).
3462 ssl_cert_instantiate becomes obsolete by this change.
3463 As soon as we've got the new code right (possibly it already is?),
3464 we have solved a couple of bugs of the earlier code where s->cert
3465 was used as if it could not have been shared with other SSL structures.
3467 Note that using the SSL API in certain dirty ways now will result
3468 in different behaviour than observed with earlier library versions:
3469 Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
3470 does not influence s as it used to.
3472 In order to clean up things more thoroughly, inside SSL_SESSION
3473 we don't use CERT any longer, but a new structure SESS_CERT
3474 that holds per-session data (if available); currently, this is
3475 the peer's certificate chain and, for clients, the server's certificate
3476 and temporary key. CERT holds only those values that can have
3477 meaningful defaults in an SSL_CTX.
3480 *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure
3481 from the internal representation. Various PKCS#7 fixes: remove some
3482 evil casts and set the enc_dig_alg field properly based on the signing
3486 *) Allow PKCS#12 password to be set from the command line or the
3487 environment. Let 'ca' get its config file name from the environment
3488 variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req'
3492 *) Allow certificate policies extension to use an IA5STRING for the
3493 organization field. This is contrary to the PKIX definition but
3494 VeriSign uses it and IE5 only recognises this form. Document 'x509'
3498 *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic,
3499 without disallowing inline assembler and the like for non-pedantic builds.
3502 *) Support Borland C++ builder.
3503 [Janez Jere <jj@void.si>, modified by Ulf Möller]
3508 *) SHA-1 cleanups and performance enhancements.
3509 [Andy Polyakov <appro@fy.chalmers.se>]
3511 *) Sparc v8plus assembler for the bignum library.
3512 [Andy Polyakov <appro@fy.chalmers.se>]
3514 *) Accept any -xxx and +xxx compiler options in Configure.
3517 *) Update HPUX configuration.
3520 *) Add missing sk_<type>_unshift() function to safestack.h
3521 [Ralf S. Engelschall]
3523 *) New function SSL_CTX_use_certificate_chain_file that sets the
3524 "extra_cert"s in addition to the certificate. (This makes sense
3525 only for "PEM" format files, as chains as a whole are not
3529 *) Support verify_depth from the SSL API.
3530 x509_vfy.c had what can be considered an off-by-one-error:
3531 Its depth (which was not part of the external interface)
3532 was actually counting the number of certificates in a chain;
3533 now it really counts the depth.
3536 *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used
3537 instead of X509err, which often resulted in confusing error
3538 messages since the error codes are not globally unique
3539 (e.g. an alleged error in ssl3_accept when a certificate
3540 didn't match the private key).
3542 *) New function SSL_CTX_set_session_id_context that allows to set a default
3543 value (so that you don't need SSL_set_session_id_context for each
3544 connection using the SSL_CTX).
3547 *) OAEP decoding bug fix.
3550 *) Support INSTALL_PREFIX for package builders, as proposed by
3554 *) New Configure options "threads" and "no-threads". For systems
3555 where the proper compiler options are known (currently Solaris
3556 and Linux), "threads" is the default.
3559 *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
3562 *) Install various scripts to $(OPENSSLDIR)/misc, not to
3563 $(INSTALLTOP)/bin -- they shouldn't clutter directories
3564 such as /usr/local/bin.
3567 *) "make linux-shared" to build shared libraries.
3568 [Niels Poppe <niels@netbox.org>]
3570 *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
3573 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
3574 extension adding in x509 utility.
3577 *) Remove NOPROTO sections and error code comments.
3580 *) Partial rewrite of the DEF file generator to now parse the ANSI
3584 *) New Configure options --prefix=DIR and --openssldir=DIR.
3587 *) Complete rewrite of the error code script(s). It is all now handled
3588 by one script at the top level which handles error code gathering,
3589 header rewriting and C source file generation. It should be much better
3590 than the old method: it now uses a modified version of Ulf's parser to
3591 read the ANSI prototypes in all header files (thus the old K&R definitions
3592 aren't needed for error creation any more) and do a better job of
3593 translating function codes into names. The old 'ASN1 error code imbedded
3594 in a comment' is no longer necessary and it doesn't use .err files which
3595 have now been deleted. Also the error code call doesn't have to appear all
3596 on one line (which resulted in some large lines...).
3599 *) Change #include filenames from <foo.h> to <openssl/foo.h>.
3602 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
3603 0 (which usually indicates a closed connection), but continue reading.
3606 *) Fix some race conditions.
3609 *) Add support for CRL distribution points extension. Add Certificate
3610 Policies and CRL distribution points documentation.
3613 *) Move the autogenerated header file parts to crypto/opensslconf.h.
3616 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
3617 8 of keying material. Merlin has also confirmed interop with this fix
3618 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
3619 [Merlin Hughes <merlin@baltimore.ie>]
3621 *) Fix lots of warnings.
3622 [Richard Levitte <levitte@stacken.kth.se>]
3624 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
3625 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
3626 [Richard Levitte <levitte@stacken.kth.se>]
3628 *) Fix problems with sizeof(long) == 8.
3629 [Andy Polyakov <appro@fy.chalmers.se>]
3631 *) Change functions to ANSI C.
3634 *) Fix typos in error codes.
3635 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf Möller]
3637 *) Remove defunct assembler files from Configure.
3640 *) SPARC v8 assembler BIGNUM implementation.
3641 [Andy Polyakov <appro@fy.chalmers.se>]
3643 *) Support for Certificate Policies extension: both print and set.
3644 Various additions to support the r2i method this uses.
3647 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
3648 return a const string when you are expecting an allocated buffer.
3651 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
3652 types DirectoryString and DisplayText.
3655 *) Add code to allow r2i extensions to access the configuration database,
3656 add an LHASH database driver and add several ctx helper functions.
3659 *) Fix an evil bug in bn_expand2() which caused various BN functions to
3660 fail when they extended the size of a BIGNUM.
3663 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
3664 support typesafe stack.
3667 *) Fix typo in SSL_[gs]et_options().
3668 [Nils Frostberg <nils@medcom.se>]
3670 *) Delete various functions and files that belonged to the (now obsolete)
3671 old X509V3 handling code.
3674 *) New Configure option "rsaref".
3677 *) Don't auto-generate pem.h.
3680 *) Introduce type-safe ASN.1 SETs.
3683 *) Convert various additional casted stacks to type-safe STACK_OF() variants.
3684 [Ben Laurie, Ralf S. Engelschall, Steve Henson]
3686 *) Introduce type-safe STACKs. This will almost certainly break lots of code
3687 that links with OpenSSL (well at least cause lots of warnings), but fear
3688 not: the conversion is trivial, and it eliminates loads of evil casts. A
3689 few STACKed things have been converted already. Feel free to convert more.
3690 In the fullness of time, I'll do away with the STACK type altogether.
3693 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
3694 specified in <certfile> by updating the entry in the index.txt file.
3695 This way one no longer has to edit the index.txt file manually for
3696 revoking a certificate. The -revoke option does the gory details now.
3697 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
3699 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
3700 `-text' option at all and this way the `-noout -text' combination was
3701 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
3702 [Ralf S. Engelschall]
3704 *) Make sure a corresponding plain text error message exists for the
3705 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
3706 verify callback function determined that a certificate was revoked.
3707 [Ralf S. Engelschall]
3709 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
3710 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
3711 all available cipers including rc5, which was forgotten until now.
3712 In order to let the testing shell script know which algorithms
3713 are available, a new (up to now undocumented) command
3714 "openssl list-cipher-commands" is used.
3717 *) Bugfix: s_client occasionally would sleep in select() when
3718 it should have checked SSL_pending() first.
3721 *) New functions DSA_do_sign and DSA_do_verify to provide access to
3722 the raw DSA values prior to ASN.1 encoding.
3725 *) Tweaks to Configure
3726 [Niels Poppe <niels@netbox.org>]
3728 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
3732 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
3735 *) New config option to avoid instructions that are illegal on the 80386.
3736 The default code is faster, but requires at least a 486.
3739 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
3740 SSL2_SERVER_VERSION (not used at all) macros, which are now the
3741 same as SSL2_VERSION anyway.
3744 *) New "-showcerts" option for s_client.
3747 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
3748 application. Various cleanups and fixes.
3751 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
3752 modify error routines to work internally. Add error codes and PBE init
3753 to library startup routines.
3756 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
3757 packing functions to asn1 and evp. Changed function names and error
3758 codes along the way.
3761 *) PKCS12 integration: and so it begins... First of several patches to
3762 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
3763 objects to objects.h
3766 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
3767 and display support for Thawte strong extranet extension.
3770 *) Add LinuxPPC support.
3771 [Jeff Dubrule <igor@pobox.org>]
3773 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
3774 bn_div_words in alpha.s.
3775 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
3777 *) Make sure the RSA OAEP test is skipped under -DRSAref because
3778 OAEP isn't supported when OpenSSL is built with RSAref.
3779 [Ulf Moeller <ulf@fitug.de>]
3781 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
3782 so they no longer are missing under -DNOPROTO.
3783 [Soren S. Jorvang <soren@t.dk>]
3786 Changes between 0.9.1c and 0.9.2b [22 Mar 1999]
3788 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
3789 doesn't work when the session is reused. Coming soon!
3792 *) Fix a security hole, that allows sessions to be reused in the wrong
3793 context thus bypassing client cert protection! All software that uses
3794 client certs and session caches in multiple contexts NEEDS PATCHING to
3795 allow session reuse! A fuller solution is in the works.
3796 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
3798 *) Some more source tree cleanups (removed obsolete files
3799 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
3800 permission on "config" script to be executable) and a fix for the INSTALL
3802 [Ulf Moeller <ulf@fitug.de>]
3804 *) Remove some legacy and erroneous uses of malloc, free instead of
3806 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
3808 *) Make rsa_oaep_test return non-zero on error.
3809 [Ulf Moeller <ulf@fitug.de>]
3811 *) Add support for native Solaris shared libraries. Configure
3812 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
3813 if someone would make that last step automatic.
3814 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
3816 *) ctx_size was not built with the right compiler during "make links". Fixed.
3819 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
3820 except NULL ciphers". This means the default cipher list will no longer
3821 enable NULL ciphers. They need to be specifically enabled e.g. with
3822 the string "DEFAULT:eNULL".
3825 *) Fix to RSA private encryption routines: if p < q then it would
3826 occasionally produce an invalid result. This will only happen with
3827 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
3830 *) Be less restrictive and allow also `perl util/perlpath.pl
3831 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
3832 because this way one can also use an interpreter named `perl5' (which is
3833 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
3834 installed as `perl').
3835 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
3837 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
3838 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
3840 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
3841 advapi32.lib to Win32 build and change the pem test comparision
3842 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
3843 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
3844 and crypto/des/ede_cbcm_enc.c.
3847 *) DES quad checksum was broken on big-endian architectures. Fixed.
3850 *) Comment out two functions in bio.h that aren't implemented. Fix up the
3851 Win32 test batch file so it (might) work again. The Win32 test batch file
3852 is horrible: I feel ill....
3855 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
3856 in e_os.h. Audit of header files to check ANSI and non ANSI
3857 sections: 10 functions were absent from non ANSI section and not exported
3858 from Windows DLLs. Fixed up libeay.num for new functions.
3861 *) Make `openssl version' output lines consistent.
3862 [Ralf S. Engelschall]
3864 *) Fix Win32 symbol export lists for BIO functions: Added
3865 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
3866 to ms/libeay{16,32}.def.
3867 [Ralf S. Engelschall]
3869 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
3870 fine under Unix and passes some trivial tests I've now added. But the
3871 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
3872 added to make sure no one expects that this stuff really works in the
3873 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
3874 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
3876 [Ralf S. Engelschall]
3878 *) Fix the generation of two part addresses in perl.
3879 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
3881 *) Add config entry for Linux on MIPS.
3882 [John Tobey <jtobey@channel1.com>]
3884 *) Make links whenever Configure is run, unless we are on Windoze.
3887 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
3888 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
3892 *) Add a useful kludge to allow package maintainers to specify compiler and
3893 other platforms details on the command line without having to patch the
3894 Configure script everytime: One now can use ``perl Configure
3895 <id>:<details>'', i.e. platform ids are allowed to have details appended
3896 to them (seperated by colons). This is treated as there would be a static
3897 pre-configured entry in Configure's %table under key <id> with value
3898 <details> and ``perl Configure <id>'' is called. So, when you want to
3899 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
3900 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
3901 now, which overrides the FreeBSD-elf entry on-the-fly.
3902 [Ralf S. Engelschall]
3904 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
3907 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
3908 on the `perl Configure ...' command line. This way one can compile
3909 OpenSSL libraries with Position Independent Code (PIC) which is needed
3910 for linking it into DSOs.
3911 [Ralf S. Engelschall]
3913 *) Remarkably, export ciphers were totally broken and no-one had noticed!
3917 *) Cleaned up the LICENSE document: The official contact for any license
3918 questions now is the OpenSSL core team under openssl-core@openssl.org.
3919 And add a paragraph about the dual-license situation to make sure people
3920 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
3921 to the OpenSSL toolkit.
3922 [Ralf S. Engelschall]
3924 *) General source tree makefile cleanups: Made `making xxx in yyy...'
3925 display consistent in the source tree and replaced `/bin/rm' by `rm'.
3926 Additonally cleaned up the `make links' target: Remove unnecessary
3927 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
3928 to speed processing and no longer clutter the display with confusing
3929 stuff. Instead only the actually done links are displayed.
3930 [Ralf S. Engelschall]
3932 *) Permit null encryption ciphersuites, used for authentication only. It used
3933 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
3934 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
3938 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
3939 signed attributes when verifying signatures (this would break them),
3940 the detached data encoding was wrong and public keys obtained using
3941 X509_get_pubkey() weren't freed.
3944 *) Add text documentation for the BUFFER functions. Also added a work around
3945 to a Win95 console bug. This was triggered by the password read stuff: the
3946 last character typed gets carried over to the next fread(). If you were
3947 generating a new cert request using 'req' for example then the last
3948 character of the passphrase would be CR which would then enter the first
3952 *) Added the new `Includes OpenSSL Cryptography Software' button as
3953 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
3954 button and can be used by applications based on OpenSSL to show the
3955 relationship to the OpenSSL project.
3956 [Ralf S. Engelschall]
3958 *) Remove confusing variables in function signatures in files
3959 ssl/ssl_lib.c and ssl/ssl.h.
3960 [Lennart Bong <lob@kulthea.stacken.kth.se>]
3962 *) Don't install bss_file.c under PREFIX/include/
3963 [Lennart Bong <lob@kulthea.stacken.kth.se>]
3965 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
3966 functions that return function pointers and has support for NT specific
3967 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
3968 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
3969 unsigned to signed types: this was killing the Win32 compile.
3972 *) Add new certificate file to stack functions,
3973 SSL_add_dir_cert_subjects_to_stack() and
3974 SSL_add_file_cert_subjects_to_stack(). These largely supplant
3975 SSL_load_client_CA_file(), and can be used to add multiple certs easily
3976 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
3977 This means that Apache-SSL and similar packages don't have to mess around
3978 to add as many CAs as they want to the preferred list.
3981 *) Experiment with doxygen documentation. Currently only partially applied to
3983 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
3984 openssl.doxy as the configuration file.
3987 *) Get rid of remaining C++-style comments which strict C compilers hate.
3988 [Ralf S. Engelschall, pointed out by Carlos Amengual]
3990 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
3991 compiled in by default: it has problems with large keys.
3994 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
3995 DH private keys and/or callback functions which directly correspond to
3996 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
3997 is needed for applications which have to configure certificates on a
3998 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
4000 For the RSA certificate situation is makes no difference, but
4001 for the DSA certificate situation this fixes the "no shared cipher"
4002 problem where the OpenSSL cipher selection procedure failed because the
4003 temporary keys were not overtaken from the context and the API provided
4004 no way to reconfigure them.
4005 The new functions now let applications reconfigure the stuff and they
4006 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
4007 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
4008 non-public-API function ssl_cert_instantiate() is used as a helper
4009 function and also to reduce code redundancy inside ssl_rsa.c.
4010 [Ralf S. Engelschall]
4012 *) Move s_server -dcert and -dkey options out of the undocumented feature
4013 area because they are useful for the DSA situation and should be
4014 recognized by the users.
4015 [Ralf S. Engelschall]
4017 *) Fix the cipher decision scheme for export ciphers: the export bits are
4018 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
4019 SSL_EXP_MASK. So, the original variable has to be used instead of the
4020 already masked variable.
4021 [Richard Levitte <levitte@stacken.kth.se>]
4023 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
4024 [Richard Levitte <levitte@stacken.kth.se>]
4026 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
4027 from `int' to `unsigned int' because it's a length and initialized by
4028 EVP_DigestFinal() which expects an `unsigned int *'.
4029 [Richard Levitte <levitte@stacken.kth.se>]
4031 *) Don't hard-code path to Perl interpreter on shebang line of Configure
4032 script. Instead use the usual Shell->Perl transition trick.
4033 [Ralf S. Engelschall]
4035 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
4036 (in addition to RSA certificates) to match the behaviour of `openssl dsa
4037 -noout -modulus' as it's already the case for `openssl rsa -noout
4038 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
4039 currently the public key is printed (a decision which was already done by
4040 `openssl dsa -modulus' in the past) which serves a similar purpose.
4041 Additionally the NO_RSA no longer completely removes the whole -modulus
4042 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
4044 [Ralf S. Engelschall]
4046 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
4047 BIO. See the source (crypto/evp/bio_ok.c) for more info.
4048 [Arne Ansper <arne@ats.cyber.ee>]
4050 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
4051 to be added. Now both 'req' and 'ca' can use new objects defined in the
4055 *) Add cool BIO that does syslog (or event log on NT).
4056 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
4058 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
4059 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
4060 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
4061 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
4064 *) Add preliminary config info for new extension code.
4067 *) Make RSA_NO_PADDING really use no padding.
4068 [Ulf Moeller <ulf@fitug.de>]
4070 *) Generate errors when private/public key check is done.
4073 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
4074 for some CRL extensions and new objects added.
4077 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
4078 key usage extension and fuller support for authority key id.
4081 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
4082 padding method for RSA, which is recommended for new applications in PKCS
4083 #1 v2.0 (RFC 2437, October 1998).
4084 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
4085 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
4086 against Bleichbacher's attack on RSA.
4087 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
4090 *) Updates to the new SSL compression code
4091 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
4093 *) Fix so that the version number in the master secret, when passed
4094 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
4095 (because the server will not accept higher), that the version number
4096 is 0x03,0x01, not 0x03,0x00
4097 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
4099 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
4100 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
4101 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
4104 *) Support for RAW extensions where an arbitrary extension can be
4105 created by including its DER encoding. See apps/openssl.cnf for
4109 *) Make sure latest Perl versions don't interpret some generated C array
4110 code as Perl array code in the crypto/err/err_genc.pl script.
4111 [Lars Weber <3weber@informatik.uni-hamburg.de>]
4113 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
4114 not many people have the assembler. Various Win32 compilation fixes and
4115 update to the INSTALL.W32 file with (hopefully) more accurate Win32
4119 *) Modify configure script 'Configure' to automatically create crypto/date.h
4120 file under Win32 and also build pem.h from pem.org. New script
4121 util/mkfiles.pl to create the MINFO file on environments that can't do a
4122 'make files': perl util/mkfiles.pl >MINFO should work.
4125 *) Major rework of DES function declarations, in the pursuit of correctness
4126 and purity. As a result, many evil casts evaporated, and some weirdness,
4127 too. You may find this causes warnings in your code. Zapping your evil
4128 casts will probably fix them. Mostly.
4131 *) Fix for a typo in asn1.h. Bug fix to object creation script
4132 obj_dat.pl. It considered a zero in an object definition to mean
4133 "end of object": none of the objects in objects.h have any zeros
4134 so it wasn't spotted.
4135 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
4137 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
4138 Masking (CBCM). In the absence of test vectors, the best I have been able
4139 to do is check that the decrypt undoes the encrypt, so far. Send me test
4140 vectors if you have them.
4143 *) Correct calculation of key length for export ciphers (too much space was
4144 allocated for null ciphers). This has not been tested!
4147 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
4148 message is now correct (it understands "crypto" and "ssl" on its
4149 command line). There is also now an "update" option. This will update
4150 the util/ssleay.num and util/libeay.num files with any new functions.
4152 perl util/mkdef.pl crypto ssl update
4153 it will update them.
4156 *) Overhauled the Perl interface (perl/*):
4157 - ported BN stuff to OpenSSL's different BN library
4158 - made the perl/ source tree CVS-aware
4159 - renamed the package from SSLeay to OpenSSL (the files still contain
4160 their history because I've copied them in the repository)
4161 - removed obsolete files (the test scripts will be replaced
4162 by better Test::Harness variants in the future)
4163 [Ralf S. Engelschall]
4165 *) First cut for a very conservative source tree cleanup:
4166 1. merge various obsolete readme texts into doc/ssleay.txt
4167 where we collect the old documents and readme texts.
4168 2. remove the first part of files where I'm already sure that we no
4169 longer need them because of three reasons: either they are just temporary
4170 files which were left by Eric or they are preserved original files where
4171 I've verified that the diff is also available in the CVS via "cvs diff
4172 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
4173 the crypto/md/ stuff).
4174 [Ralf S. Engelschall]
4176 *) More extension code. Incomplete support for subject and issuer alt
4177 name, issuer and authority key id. Change the i2v function parameters
4178 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
4179 what that's for :-) Fix to ASN1 macro which messed up
4180 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
4183 *) Preliminary support for ENUMERATED type. This is largely copied from the
4187 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
4188 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
4190 *) Make sure `make rehash' target really finds the `openssl' program.
4191 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
4193 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
4194 like to hear about it if this slows down other processors.
4197 *) Add CygWin32 platform information to Configure script.
4198 [Alan Batie <batie@aahz.jf.intel.com>]
4200 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
4201 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
4203 *) New program nseq to manipulate netscape certificate sequences
4206 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
4210 *) Fixes to BN code. Previously the default was to define BN_RECURSION
4211 but the BN code had some problems that would cause failures when
4212 doing certificate verification and some other functions.
4213 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
4215 *) Add ASN1 and PEM code to support netscape certificate sequences.
4218 *) Add ASN1 and PEM code to support netscape certificate sequences.
4221 *) Add several PKIX and private extended key usage OIDs.
4224 *) Modify the 'ca' program to handle the new extension code. Modify
4225 openssl.cnf for new extension format, add comments.
4228 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
4229 and add a sample to openssl.cnf so req -x509 now adds appropriate
4233 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
4234 error code, add initial support to X509_print() and x509 application.
4237 *) Takes a deep breath and start addding X509 V3 extension support code. Add
4238 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
4239 stuff is currently isolated and isn't even compiled yet.
4242 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
4243 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
4244 Removed the versions check from X509 routines when loading extensions:
4245 this allows certain broken certificates that don't set the version
4246 properly to be processed.
4249 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
4250 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
4251 can still be regenerated with "make depend".
4254 *) Spelling mistake in C version of CAST-128.
4255 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
4257 *) Changes to the error generation code. The perl script err-code.pl
4258 now reads in the old error codes and retains the old numbers, only
4259 adding new ones if necessary. It also only changes the .err files if new
4260 codes are added. The makefiles have been modified to only insert errors
4261 when needed (to avoid needlessly modifying header files). This is done
4262 by only inserting errors if the .err file is newer than the auto generated
4263 C file. To rebuild all the error codes from scratch (the old behaviour)
4264 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
4265 or delete all the .err files.
4268 *) CAST-128 was incorrectly implemented for short keys. The C version has
4269 been fixed, but is untested. The assembler versions are also fixed, but
4270 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
4271 to regenerate it if needed.
4272 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
4273 Hagino <itojun@kame.net>]
4275 *) File was opened incorrectly in randfile.c.
4276 [Ulf Möller <ulf@fitug.de>]
4278 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
4279 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
4280 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
4281 al: it's just almost always a UTCTime. Note this patch adds new error
4282 codes so do a "make errors" if there are problems.
4285 *) Correct Linux 1 recognition in config.
4286 [Ulf Möller <ulf@fitug.de>]
4288 *) Remove pointless MD5 hash when using DSA keys in ca.
4289 [Anonymous <nobody@replay.com>]
4291 *) Generate an error if given an empty string as a cert directory. Also
4292 generate an error if handed NULL (previously returned 0 to indicate an
4293 error, but didn't set one).
4294 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
4296 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
4299 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
4300 parameters. This was causing a warning which killed off the Win32 compile.
4303 *) Remove C++ style comments from crypto/bn/bn_local.h.
4304 [Neil Costigan <neil.costigan@celocom.com>]
4306 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
4307 based on a text string, looking up short and long names and finally
4308 "dot" format. The "dot" format stuff didn't work. Added new function
4309 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
4310 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
4311 OID is not part of the table.
4314 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
4315 X509_LOOKUP_by_alias().
4318 *) Sort openssl functions by name.
4321 *) Get the gendsa program working (hopefully) and add it to app list. Remove
4322 encryption from sample DSA keys (in case anyone is interested the password
4326 *) Make _all_ *_free functions accept a NULL pointer.
4327 [Frans Heymans <fheymans@isaserver.be>]
4329 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
4331 [Anonymous <nobody@replay.com>]
4333 *) s_server should send the CAfile as acceptable CAs, not its own cert.
4334 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
4336 *) Don't blow it for numeric -newkey arguments to apps/req.
4337 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
4339 *) Temp key "for export" tests were wrong in s3_srvr.c.
4340 [Anonymous <nobody@replay.com>]
4342 *) Add prototype for temp key callback functions
4343 SSL_CTX_set_tmp_{rsa,dh}_callback().
4346 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
4347 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
4350 *) X509_name_add_entry() freed the wrong thing after an error.
4351 [Arne Ansper <arne@ats.cyber.ee>]
4353 *) rsa_eay.c would attempt to free a NULL context.
4354 [Arne Ansper <arne@ats.cyber.ee>]
4356 *) BIO_s_socket() had a broken should_retry() on Windoze.
4357 [Arne Ansper <arne@ats.cyber.ee>]
4359 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
4360 [Arne Ansper <arne@ats.cyber.ee>]
4362 *) Make sure the already existing X509_STORE->depth variable is initialized
4363 in X509_STORE_new(), but document the fact that this variable is still
4364 unused in the certificate verification process.
4365 [Ralf S. Engelschall]
4367 *) Fix the various library and apps files to free up pkeys obtained from
4368 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
4371 *) Fix reference counting in X509_PUBKEY_get(). This makes
4372 demos/maurice/example2.c work, amongst others, probably.
4373 [Steve Henson and Ben Laurie]
4375 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
4376 `openssl' and second, the shortcut symlinks for the `openssl <command>'
4377 are no longer created. This way we have a single and consistent command
4378 line interface `openssl <command>', similar to `cvs <command>'.
4379 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
4381 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
4382 BIT STRING wrapper always have zero unused bits.
4385 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
4388 *) Make the top-level INSTALL documentation easier to understand.
4391 *) Makefiles updated to exit if an error occurs in a sub-directory
4392 make (including if user presses ^C) [Paul Sutton]
4394 *) Make Montgomery context stuff explicit in RSA data structure.
4397 *) Fix build order of pem and err to allow for generated pem.h.
4400 *) Fix renumbering bug in X509_NAME_delete_entry().
4403 *) Enhanced the err-ins.pl script so it makes the error library number
4404 global and can add a library name. This is needed for external ASN1 and
4405 other error libraries.
4408 *) Fixed sk_insert which never worked properly.
4411 *) Fix ASN1 macros so they can handle indefinite length construted
4412 EXPLICIT tags. Some non standard certificates use these: they can now
4416 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
4417 into a single doc/ssleay.txt bundle. This way the information is still
4418 preserved but no longer messes up this directory. Now it's new room for
4419 the new set of documenation files.
4420 [Ralf S. Engelschall]
4422 *) SETs were incorrectly DER encoded. This was a major pain, because they
4423 shared code with SEQUENCEs, which aren't coded the same. This means that
4424 almost everything to do with SETs or SEQUENCEs has either changed name or
4425 number of arguments.
4426 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
4428 *) Fix test data to work with the above.
4431 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
4432 was already fixed by Eric for 0.9.1 it seems.
4433 [Ben Laurie - pointed out by Ulf Möller <ulf@fitug.de>]
4435 *) Autodetect FreeBSD3.
4438 *) Fix various bugs in Configure. This affects the following platforms:
4442 unixware-2.0-pentium
4446 *) Eliminate generated files from CVS. Reorder tests to regenerate files
4447 before they are needed.
4450 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
4454 Changes between 0.9.1b and 0.9.1c [23-Dec-1998]
4456 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
4457 changed SSLeay to OpenSSL in version strings.
4458 [Ralf S. Engelschall]
4460 *) Some fixups to the top-level documents.
4463 *) Fixed the nasty bug where rsaref.h was not found under compile-time
4464 because the symlink to include/ was missing.
4465 [Ralf S. Engelschall]
4467 *) Incorporated the popular no-RSA/DSA-only patches
4468 which allow to compile a RSA-free SSLeay.
4469 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
4471 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
4472 when "ssleay" is still not found.
4473 [Ralf S. Engelschall]
4475 *) Added more platforms to Configure: Cray T3E, HPUX 11,
4476 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
4478 *) Updated the README file.
4479 [Ralf S. Engelschall]
4481 *) Added various .cvsignore files in the CVS repository subdirs
4482 to make a "cvs update" really silent.
4483 [Ralf S. Engelschall]
4485 *) Recompiled the error-definition header files and added
4486 missing symbols to the Win32 linker tables.
4487 [Ralf S. Engelschall]
4489 *) Cleaned up the top-level documents;
4490 o new files: CHANGES and LICENSE
4491 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
4492 o merged COPYRIGHT into LICENSE
4493 o removed obsolete TODO file
4494 o renamed MICROSOFT to INSTALL.W32
4495 [Ralf S. Engelschall]
4497 *) Removed dummy files from the 0.9.1b source tree:
4498 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
4499 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f

4502 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
4503 [Ralf S. Engelschall]
4505 *) Added various platform portability fixes.
4508 *) The Genesis of the OpenSSL rpject:
4509 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
4510 Young and Tim J. Hudson created while they were working for C2Net until
4512 [The OpenSSL Project]
4515 Changes between 0.9.0b and 0.9.1b [not released]
4517 *) Updated a few CA certificates under certs/
4520 *) Changed some BIGNUM api stuff.
4523 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
4524 DGUX x86, Linux Alpha, etc.
4527 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
4528 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
4532 *) Add -strparse option to asn1pars program which parses nested
4534 [Dr Stephen Henson <shenson@bigfoot.com>]
4536 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
4539 *) DSA fix for "ca" program.
4542 *) Added "-genkey" option to "dsaparam" program.
4545 *) Added RIPE MD160 (rmd160) message digest.
4548 *) Added -a (all) option to "ssleay version" command.
4551 *) Added PLATFORM define which is the id given to Configure.
4554 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
4557 *) Extended the ASN.1 parser routines.
4560 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
4563 *) Added a BN_CTX to the BN library.
4566 *) Fixed the weak key values in DES library
4569 *) Changed API in EVP library for cipher aliases.
4572 *) Added support for RC2/64bit cipher.
4575 *) Converted the lhash library to the crypto/mem.c functions.
4578 *) Added more recognized ASN.1 object ids.
4581 *) Added more RSA padding checks for SSL/TLS.
4584 *) Added BIO proxy/filter functionality.
4587 *) Added extra_certs to SSL_CTX which can be used
4588 send extra CA certificates to the client in the CA cert chain sending
4589 process. It can be configured with SSL_CTX_add_extra_chain_cert().
4592 *) Now Fortezza is denied in the authentication phase because
4593 this is key exchange mechanism is not supported by SSLeay at all.
4596 *) Additional PKCS1 checks.
4599 *) Support the string "TLSv1" for all TLS v1 ciphers.
4602 *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
4603 ex_data index of the SSL context in the X509_STORE_CTX ex_data.
4606 *) Fixed a few memory leaks.
4609 *) Fixed various code and comment typos.
4612 *) A minor bug in ssl/s3_clnt.c where there would always be 4 0
4613 bytes sent in the client random.
