- Changes between 0.9.6 and 0.9.7 [xx XXX 2000]
+ Changes between 0.9.6 and 0.9.7 [xx XXX 2001]
+
+ Both OpenSSL 0.9.6a (bugfix release, 5 Apr 2001) and OpenSSL 0.9.7
+ are based on OpenSSL 0.9.6.
+ Change log entries are tagged as follows:
+ -) applies to 0.9.6a (/0.9.6b) only
+ *) applies to 0.9.6a (/0.9.6b) and 0.9.7
+ +) applies to 0.9.7 only
+
+ +) Implement binary inversion algorithm for BN_mod_inverse in addition
+ to the algorithm using long divison. The binary algorithm can be
+ used only if the modulus is odd. On 32-bit systems, it is faster
+ only for relatively small moduli (roughly 20-30% for 128-bit moduli,
+ roughly 5-15% for 256-bit moduli), so we use it only for moduli
+ up to 450 bits. In 64-bit environments, the binary algorithm
+ appears to be advantageous for much longer moduli; here we use it
+ for moduli up to 2048 bits.
+ [Bodo Moeller]
+
+ *) Change bctest again: '-x' expressions are not available in all
+ versions of 'test'.
+ [Bodo Moeller]
+
+ -) OpenSSL 0.9.6a released [5 Apr 2001]
+
+ *) Fix a couple of memory leaks in PKCS7_dataDecode()
+ [Steve Henson, reported by Heyun Zheng <hzheng@atdsprint.com>]
*) Change Configure and Makefiles to provide EXE_EXT, which will contain
the default extension for executables, if any. Also, make the perl
CygWin.
[Richard Levitte]
- *) Rewrite CHOICE field setting in ASN1_item_ex_d2i(). The old code
+ +) Rewrite CHOICE field setting in ASN1_item_ex_d2i(). The old code
could not support the combine flag in choice fields.
[Steve Henson]
+ -) Fix for asn1_GetSequence() for indefinite length constructed data.
+ If SEQUENCE is length is indefinite just set c->slen to the total
+ amount of data available.
+ [Steve Henson, reported by shige@FreeBSD.org]
+ [This change does not apply to 0.9.7.]
+
*) Change bctest to avoid here-documents inside command substitution
(workaround for FreeBSD /bin/sh bug).
+ For compatibility with Ultrix, avoid shell functions (introduced
+ in the bctest version that searches along $PATH).
[Bodo Moeller]
*) Rename 'des_encrypt' to 'des_encrypt1'. This avoids the clashes
*) Disabled incorrect Alpha assembler code.
[Richard Levitte]
+ -) Fix PKCS#7 decode routines so they correctly update the length
+ after reading an EOC for the EXPLICIT tag.
+ [Steve Henson]
+ [This change does not apply to 0.9.7.]
+
*) Fix bug in PKCS#12 key generation routines. This was triggered
if a 3DES key was generated with a 0 initial byte. Include
PKCS12_BROKEN_KEYGEN compilation option to retain the old
it when found.
[Tim Rice <tim@multitalents.net> via Richard Levitte]
- *) Add a 'copy_extensions' option to the 'ca' utility. This copies
+ +) Add a 'copy_extensions' option to the 'ca' utility. This copies
extensions from a certificate request to the certificate.
[Steve Henson]
- *) Allow multiple 'certopt' and 'nameopt' options to be separated
+ +) Allow multiple 'certopt' and 'nameopt' options to be separated
by commas. Add 'namopt' and 'certopt' options to the 'ca' config
file: this allows the display of the certificate about to be
signed to be customised, to allow certain fields to be included
don't write to the wrong index in ERR_set_error_data.
[Bodo Moeller]
- *) Function EC_POINTs_mul for simultaneous scalar multiplication
+ +) Function EC_POINTs_mul for simultaneous scalar multiplication
of an arbitrary number of elliptic curve points, optionally
including the generator defined for the EC_GROUP.
EC_POINT_mul is a simple wrapper function for the typical case
generator).
[Bodo Moeller]
- *) First EC_METHODs for curves over GF(p):
+ +) First EC_METHODs for curves over GF(p):
EC_GFp_simple_method() uses the basic BN_mod_mul and BN_mod_sqr
operations and provides various method functions that can also
implementation directly derived from source code provided by
Lenka Fibikova <fibikova@exp-math.uni-essen.de>]

+ +) Framework for elliptic curves (crypto/ec/ec.h, crypto/ec/ec_lcl.h,
crypto/ec/ec_lib.c):
Curves are EC_GROUP objects (with an optional group generator)
than GF(p), some functions are limited to that for now.
[Bodo Moeller]
- *) Add the -HTTP option to s_server. It is similar to -WWW, but requires
+ +) Add the -HTTP option to s_server. It is similar to -WWW, but requires
that the file contains a complete HTTP response.
[Richard Levitte]
- *) Add the ec directory to mkdef.pl and mkfiles.pl. In mkdef.pl
+ +) Add the ec directory to mkdef.pl and mkfiles.pl. In mkdef.pl
change the def and num file printf format specifier from "%-40sXXX"
to "%-39s XXX". The latter will always guarantee a space after the
field while the former will cause them to run together if the field
is 40 of more characters long.
[Steve Henson]
- *) Constify the cipher and digest 'method' functions and structures
+ +) Constify the cipher and digest 'method' functions and structures
and modify related functions to take constant EVP_MD and EVP_CIPHER
pointers.
[Steve Henson]
*) Replace rdtsc with _emit statements for VC++ version 5.
[Jeremy Cooper <jeremy@baymoo.org>]
- *) Hide BN_CTX structure details in bn_lcl.h instead of publishing them
+ +) Hide BN_CTX structure details in bn_lcl.h instead of publishing them
in <openssl/bn.h>. Also further increase BN_CTX_NUM to 32.
[Bodo Moeller]
- *) Modify EVP_Digest*() routines so they now return values. Although the
+ +) Modify EVP_Digest*() routines so they now return values. Although the
internal software routines can never fail additional hardware versions
might.
[Steve Henson]
- *) Clean up crypto/err/err.h and change some error codes to avoid conflicts:
+ +) Clean up crypto/err/err.h and change some error codes to avoid conflicts:
Previously ERR_R_FATAL was too small and coincided with ERR_LIB_PKCS7
(= ERR_R_PKCS7_LIB); it is now 64 instead of 32.
Add new error code 'ERR_R_INTERNAL_ERROR'.
[Bodo Moeller]
- *) Don't overuse locks in crypto/err/err.c: For data retrieval, CRYPTO_r_lock
+ +) Don't overuse locks in crypto/err/err.c: For data retrieval, CRYPTO_r_lock
suffices.
[Bodo Moeller]
- *) New option '-subj arg' for 'openssl req' and 'openssl ca'. This
+ +) New option '-subj arg' for 'openssl req' and 'openssl ca'. This
sets the subject name for a new request or supersedes the
subject name in a given request. Formats that can be parsed are
'CN=Some Name, OU=myOU, C=IT'
*) Make it possible to reuse SSLv2 sessions.
[Richard Levitte]
- *) Introduce the possibility to access global variables through
+ +) Introduce the possibility to access global variables through
functions on platform were that's the best way to handle exporting
global variables in shared libraries. To enable this functionality,
one must configure with "EXPORT_VAR_AS_FN" or defined the C macro
X509_NAME_get_index_by_NID() since 0 is a valid index.
[Steve Henson reported by Massimiliano Pala <madwolf@opensca.org>]
- *) In BN_div() keep a copy of the sign of 'num' before writing the
+ +) In BN_div() keep a copy of the sign of 'num' before writing the
result to 'rm' because if rm==num the value will be overwritten
and produce the wrong result if 'num' is negative: this caused
problems with BN_mod() and BN_nnmod().
[Steve Henson]
- *) Function OCSP_request_verify(). This checks the signature on an
+ +) Function OCSP_request_verify(). This checks the signature on an
OCSP request and verifies the signer certificate. The signer
certificate is just checked for a generic purpose and OCSP request
trust settings.
[Steve Henson]
- *) Add OCSP_check_validity() function to check the validity of OCSP
+ +) Add OCSP_check_validity() function to check the validity of OCSP
responses. OCSP responses are prepared in real time and may only
be a few seconds old. Simply checking that the current time lies
between thisUpdate and nextUpdate max reject otherwise valid responses
ocsp utility.
[Steve Henson]
- *) If signature or public key algorithm is unrecognized print out its

OID rather that just UNKOWN.
[Steve Henson]
PKCS7_verify() fails with non detached data.
[Steve Henson]
- *) Change OCSP_cert_to_id() to tolerate a NULL subject certificate and
+ +) Change OCSP_cert_to_id() to tolerate a NULL subject certificate and
OCSP_cert_id_new() a NULL serialNumber. This allows a partial certificate
ID to be generated from the issuer certificate alone which can then be
passed to OCSP_id_issuer_cmp().
[Steve Henson]
- *) New compilation option ASN1_ITEM_FUNCTIONS. This causes the new
+ +) New compilation option ASN1_ITEM_FUNCTIONS. This causes the new
ASN1 modules to export functions returning ASN1_ITEM pointers
instead of the ASN1_ITEM structures themselves. This adds several
new macros which allow the underlying ASN1 function/structure to
functions returning pointers to structures is not.
[Steve Henson]
- *) Add support for overriding the generation of SSL/TLS session IDs.
+ +) Add support for overriding the generation of SSL/TLS session IDs.
These callbacks can be registered either in an SSL_CTX or per SSL.
The purpose of this is to allow applications to control, if they wish,
the arbitrary values chosen for use as session IDs, particularly as it
to use such a feature) has been added to "s_server".
[Geoff Thorpe, Lutz Jaenicke]
- *) Modify mkdef.pl to recognise and parse prprocessor conditionals
+ +) Modify mkdef.pl to recognise and parse prprocessor conditionals
of the form '#if defined(...) || defined(...) || ...' and
'#if !defined(...) && !defined(...) && ...'. This also avoids
the growing number of special cases it was previously handling.
New function OPENSSL_issetugid().
[Ulf Moeller]
- *) Make all configuration macros available for application by making
+ +) Make all configuration macros available for application by making
sure they are available in opensslconf.h, by giving them names starting
with "OPENSSL_" to avoid conflicts with other packages and by making
sure e_os2.h will cover all platform-specific cases together with
what is available.
[Richard Levitte]
- *) New option -set_serial to 'req' and 'x509' this allows the serial
+ +) New option -set_serial to 'req' and 'x509' this allows the serial
number to use to be specified on the command line. Previously self
signed certificates were hard coded with serial number 0 and the
CA options of 'x509' had to use a serial number in a file which was
assumption that thread ID 0 is impossible).
[Bodo Moeller]
- *) New options to 'ca' utility to support V2 CRL entry extensions.
+ +) New options to 'ca' utility to support V2 CRL entry extensions.
Currently CRL reason, invalidity date and hold instruction are
supported. Add new CRL extensions to V3 code and some new objects.
[Steve Henson]
*) Add "-rand" option also to s_client and s_server.
[Lutz Jaenicke]
- *) New function EVP_CIPHER_CTX_set_padding() this is used to
+ +) New function EVP_CIPHER_CTX_set_padding() this is used to
disable standard block padding (aka PKCS#5 padding) in the EVP
API, which was previously mandatory. This means that the data is
not padded in any way and so the total length much be a multiple
of the block size, otherwise an error occurs.
[Steve Henson]
- *) Initial (incomplete) OCSP SSL support.
+ +) Initial (incomplete) OCSP SSL support.
[Steve Henson]
*) Fix CPU detection on Irix 6.x.
[Kurt Hockenbury <khockenb@stevens-tech.edu> and
"Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
- *) New function OCSP_parse_url(). This splits up a URL into its host,
+ +) New function OCSP_parse_url(). This splits up a URL into its host,
port and path components: primarily to parse OCSP URLs. New -url
option to ocsp utility.
[Steve Henson]
- *) New nonce behavior. The return value of OCSP_check_nonce() now
+ +) New nonce behavior. The return value of OCSP_check_nonce() now
reflects the various checks performed. Applications can decide
whether to tolerate certain situations such as an absent nonce
in a response when one was present in a request: the ocsp application
the request is nonce-less.
[Steve Henson]
+ *) Fix X509_NAME bug which produced incorrect encoding if X509_NAME
+ was empty.
+ [This change does not apply to 0.9.7.]
+
*) Use the cached encoding of an X509_NAME structure rather than
copying it. This is apparently the reason for the libsafe "errors"
but the code is actually correct.
[Steve Henson]
- *) Disable stdin buffering in load_cert (apps/apps.c) so that no certs are
+ +) Disable stdin buffering in load_cert (apps/apps.c) so that no certs are
skipped when using openssl x509 multiple times on a single input file,
e.g. "(openssl x509 -out cert1; openssl x509 -out cert2) <certs".
[Bodo Moeller]
- *) Make ASN1_UTCTIME_set_string() and ASN1_GENERALIZEDTIME_set_string()
+ +) Make ASN1_UTCTIME_set_string() and ASN1_GENERALIZEDTIME_set_string()
set string type: to handle setting ASN1_TIME structures. Fix ca
utility to correctly initialize revocation date of CRLs.
[Steve Henson]
- *) New option SSL_OP_CIPHER_SERVER_PREFERENCE allows the server to override
+ +) New option SSL_OP_CIPHER_SERVER_PREFERENCE allows the server to override
the clients preferred ciphersuites and rather use its own preferences.
Should help to work around M$ SGC (Server Gated Cryptography) bug in
Internet Explorer by ensuring unchanged hash method during stepup.
[Lutz Jaenicke]
- *) Make mkdef.pl recognise all DECLARE_ASN1 macros, change rijndael
+ +) Make mkdef.pl recognise all DECLARE_ASN1 macros, change rijndael
to aes and add a new 'exist' option to print out symbols that don't
appear to exist.
[Steve Henson]

and leaves the highest bit random.
[Ulf Moeller, Bodo Moeller]
- *) Update Rijndael code to version 3.0 and change EVP AES ciphers to

handle the new API. Currently only ECB, CBC modes supported. Add new
AES OIDs. Add TLS AES ciphersuites as described in the "AES Ciphersuites
for TLS" draft-ietf-tls-ciphersuite-03.txt.
*) Fix potential buffer overrun for EBCDIC.
[Ulf Moeller]
- *) New function OCSP_copy_nonce() to copy nonce value (if present) from

request to response.
[Steve Henson]
- *) Functions for OCSP responders. OCSP_request_onereq_count(),
+ +) Functions for OCSP responders. OCSP_request_onereq_count(),
OCSP_request_onereq_get0(), OCSP_onereq_get0_id() and OCSP_id_get0_info()
extract information from a certificate request. OCSP_response_create()
creates a response and optionally adds a basic response structure.
(converts ASN1_TIME to GeneralizedTime).
[Steve Henson]
- *) Various new functions. EVP_Digest() combines EVP_Digest{Init,Update,Final}()
+ +) Various new functions. EVP_Digest() combines EVP_Digest{Init,Update,Final}()
in a single operation. X509_get0_pubkey_bitstr() extracts the public_key
structure from a certificate. X509_pubkey_digest() digests tha public_key
contents: this is used in various key identifiers.
headers.
[Richard Levitte]
- *) Make sk_sort() tolerate a NULL argument.
+ +) Make sk_sort() tolerate a NULL argument.
[Steve Henson reported by Massimiliano Pala <madwolf@comune.modena.it>]
- *) New OCSP verify flag OCSP_TRUSTOTHER. When set the "other" certificates
+ +) New OCSP verify flag OCSP_TRUSTOTHER. When set the "other" certificates
passed by the function are trusted implicitly. If any of them signed the
reponse then it is assumed to be valid and is not verified.
[Steve Henson]
+ -) Make the CRL encoding routines work with empty SEQUENCE OF. The
+ macros previously used would not encode an empty SEQUENCE OF
+ and break the signature.
+ [Steve Henson]
+ [This change does not apply to 0.9.7.]
+
*) Zero the premaster secret after deriving the master secret in
DH ciphersuites.

to data. This was previously part of the PKCS7 ASN1 code. This
was causing problems with OpenSSL created PKCS#12 and PKCS#7 structures.
[Steve Henson, reported by Kenneth R. Robinette
<support@securenetterm.com>]
- *) Add CRYPTO_push_info() and CRYPTO_pop_info() calls to new ASN1
+ +) Add CRYPTO_push_info() and CRYPTO_pop_info() calls to new ASN1
routines: without these tracing memory leaks is very painful.
Fix leaks in PKCS12 and PKCS7 routines.
[Steve Henson]
*) ./config script fixes.
[Ulf Moeller, Richard Levitte]
- *) Make X509_time_adj() cope with the new behaviour of ASN1_TIME_new().
+ +) Make X509_time_adj() cope with the new behaviour of ASN1_TIME_new().
Previously it initialised the 'type' argument to V_ASN1_UTCTIME which
effectively meant GeneralizedTime would never be used. Now it
is initialised to -1 but X509_time_adj() now has to check the value
[Steve Henson, reported by Kenneth R. Robinette
<support@securenetterm.com>]
- *) Fixes to BN_to_ASN1_INTEGER when bn is zero. This would previously
+ +) Fixes to BN_to_ASN1_INTEGER when bn is zero. This would previously
result in a zero length in the ASN1_INTEGER structure which was
not consistent with the structure when d2i_ASN1_INTEGER() was used
and would cause ASN1_INTEGER_cmp() to fail. Enhance s2i_ASN1_INTEGER()
*) Fix 'openssl passwd -1'.
[Bodo Moeller]
- *) Add summary printout to ocsp utility. The various functions which
+ +) Add summary printout to ocsp utility. The various functions which
convert status values to strings have been renamed to:
OCSP_response_status_str(), OCSP_cert_status_str() and
OCSP_crl_reason_str() and are no longer static. New options
printout format cleaned up.
[Steve Henson]
- *) Add additional OCSP certificate checks. These are those specified
+ +) Add additional OCSP certificate checks. These are those specified
in RFC2560. This consists of two separate checks: the CA of the
certificate being checked must either be the OCSP signer certificate
or the issuer of the OCSP signer certificate. In the latter case the
in the OCSP_CERTID structures of the response.
[Steve Henson]
- *) Initial OCSP certificate verification added to OCSP_basic_verify()
+ +) Initial OCSP certificate verification added to OCSP_basic_verify()
and related routines. This uses the standard OpenSSL certificate
verify routines to perform initial checks (just CA validity) and
to obtain the certificate chain. Then additional checks will be
chains to that CA is an acceptable OCSP signing certificate.
[Steve Henson]
- *) New '-extfile ...' option to 'openssl ca' for reading X.509v3
+ +) New '-extfile ...' option to 'openssl ca' for reading X.509v3
extensions from a separate configuration file.
As when reading extensions from the main configuration file,
the '-extensions ...' option may be used for specifying the
by adding an extra length parameter to asc2uni().
[Steve Henson, reported by <oddissey@samsung.co.kr>]
- *) New OCSP utility. Allows OCSP requests to be generated or
+ +) New OCSP utility. Allows OCSP requests to be generated or
read. The request can be sent to a responder and the output
parsed, outputed or printed in text form. Not complete yet:
still needs to check the OCSP response validity.
[Steve Henson]
- *) New subcommands for 'openssl ca':
+ +) New subcommands for 'openssl ca':
'openssl ca -status <serial>' prints the status of the cert with
the given serial number (according to the index file).
'openssl ca -updatedb' updates the expiry status of certificates
in the index file.
[Massimiliano Pala <madwolf@comune.modena.it>]
- *) New '-newreq-nodes' command option to CA.pl. This is like
+ +) New '-newreq-nodes' command option to CA.pl. This is like
'-newreq', but calls 'openssl req' with the '-nodes' option
so that the resulting key is not encrypted.
[Damien Miller <djm@mindrot.org>]
- *) New configuration for the GNU Hurd.

is currently incomplete. Currently just finds the signer's
certificate and verifies the signature on the response.
[Steve Henson]

file name and line number information in additional arguments
(a const char* and an int). The basic functionality remains, as
well as the original possibility to just replace malloc(),
These are present in some PKCS#12 files.
[Steve Henson]
- *) Finish off removing the remaining LHASH function pointer casts.
+ +) Finish off removing the remaining LHASH function pointer casts.
There should no longer be any prototype-casting required when using
the LHASH abstraction, and any casts that remain are "bugs". See
the callback types and macros at the head of lhash.h for details
(and "OBJ_cleanup" in crypto/objects/obj_dat.c as an example).
[Geoff Thorpe]
- *) Add automatic query of EGD sockets in RAND_poll() for the unix variant.
+ +) Add automatic query of EGD sockets in RAND_poll() for the unix variant.
If an EGD or PRNGD is running and enough entropy is returned, automatic
seeding like with /dev/[u]random will be performed.
Positions tried are: /etc/entropy, /var/run/egd-pool.
[Lutz Jaenicke]
- *) Change the Unix RAND_poll() variant to be able to poll several

random devices, as specified by DEVRANDOM, until a sufficient amount
of data has been collected. We spend at most 10 ms on each file
(select timeout) and read in non-blocking mode. DEVRANDOM now
For VMS, there's a currently-empty rand_vms.c.
[Richard Levitte]

provide utility functions which an application needing
to issue a request to an OCSP responder and analyse the
response will typically need: as opposed to those which an

This doesn't copy the supplied OCSP_CERTID and avoids the
need to free up the newly created id. Change return type
to OCSP_ONEREQ to return the internal OCSP_ONEREQ structure.

various functions. Extensions are now handled using the new
OCSP extension code. New simple OCSP HTTP function which
can be used to send requests and parse the response.
[Steve Henson]

+ +) Fix the PKCS#7 (S/MIME) code to work with new ASN1. Two new
ASN1_ITEM structures help with sign and verify. PKCS7_ATTR_SIGN
uses the special reorder version of SET OF to sort the attributes
and reorder them to match the encoded order. This resolves a long
to produce the required SET OF.
[Steve Henson]
- *) Have mk1mf.pl generate the macros OPENSSL_BUILD_SHLIBCRYPTO and
+ +) Have mk1mf.pl generate the macros OPENSSL_BUILD_SHLIBCRYPTO and
OPENSSL_BUILD_SHLIBSSL and use them appropriately in the header
files to get correct declarations of the ASN.1 item variables.
[Richard Levitte]
- *) Rewrite of PKCS#12 code to use new ASN1 functionality. Replace many
+ +) Rewrite of PKCS#12 code to use new ASN1 functionality. Replace many
PKCS#12 macros with real functions. Fix two unrelated ASN1 bugs:
asn1_check_tlen() would sometimes attempt to use 'ctx' when it was
NULL and ASN1_TYPE was not dereferenced properly in asn1_ex_c2i().
ASN1_ITEM and no wrapper functions.
[Steve Henson]
- *) New functions or ASN1_item_d2i_fp() and ASN1_item_d2i_bio(). These
+ +) New functions or ASN1_item_d2i_fp() and ASN1_item_d2i_bio(). These
replace the old function pointer based I/O routines. Change most of
the *_d2i_bio() and *_d2i_fp() functions to use these.
[Steve Henson]
- *) Enhance mkdef.pl to be more accepting about spacing in C preprocessor
+ +) Enhance mkdef.pl to be more accepting about spacing in C preprocessor
lines, recognice more "algorithms" that can be deselected, and make
it complain about algorithm deselection that isn't recognised.
[Richard Levitte]
- *) New ASN1 functions to handle dup, sign, verify, digest, pack and
+ +) New ASN1 functions to handle dup, sign, verify, digest, pack and
unpack operations in terms of ASN1_ITEM. Modify existing wrappers
to use new functions. Add NO_ASN1_OLD which can be set to remove
some old style ASN1 functions: this can be used to determine if old
code will still work when these eventually go away.
[Steve Henson]
- *) New extension functions for OCSP structures, these follow the

same conventions as certificates and CRLs.
[Steve Henson]
- *) New function X509V3_add1_i2d(). This automatically encodes and
+ +) New function X509V3_add1_i2d(). This automatically encodes and
adds an extension. Its behaviour can be customised with various
flags to append, replace or delete. Various wrappers added for
certifcates and CRLs.
[Steve Henson]

entries for variables.
[Steve Henson]
*) Fix a deadlock in CRYPTO_mem_leaks().
[Bodo Moeller]
- *) Add functionality to apps/openssl.c for detecting locking

problems: As the program is single-threaded, all we have
to do is register a locking callback using an array for
storing which locks are currently held by the program.
