Changes between 0.9.5a and 0.9.6 [xx XXX 2000]
*) Fix BN_mul_word for the case where the word is 0. (We have to use
BN_zero, we may not return a BIGNUM with an array consisting of
words set to zero.)
[Bodo Moeller]
*) Avoid calling abort() from within the library when problems are
detected, except if preprocessor symbols have been defined
(such as REF_CHECK, BN_DEBUG etc.).
[Bodo Moeller]
*) New openssl application 'rsautl'. This utility can be
used for low level RSA operations. DER public key
BIO/fp routines also added.
[Steve Henson]
*) New Configure entry and patches for compiling on QNX 4.
[Andreas Schneider <andreas@ds3.etech.fh-hamburg.de>]
*) A demo state-machine implementation was sponsored by
Nuron (http://www.nuron.com/) and is now available in
demos/state_machine.
[Ben Laurie]
*) New options added to the 'dgst' utility for signature
generation and verification.
[Steve Henson]
*) Unrecognized PKCS#7 content types are now handled via a
catch all ASN1_TYPE structure. This allows unsupported
types to be stored as a "blob" and an application can
encode and decode it manually.
[Steve Henson]
*) Fix various signed/unsigned issues to make a_strex.c
compile under VC++.
[Oscar Jacobsson <oscar.jacobsson@celocom.com>]
*) ASN1 fixes. i2d_ASN1_OBJECT was not returning the correct
length if passed a buffer. ASN1_INTEGER_to_BN failed
if passed a NULL BN and its argument was negative.
[Steve Henson, pointed out by Sven Heiberg <sven@tartu.cyber.ee>]
*) Modification to PKCS#7 encoding routines to output definite
length encoding. Since currently the whole structures are in
memory there's not real point in using indefinite length
constructed encoding. However if OpenSSL is compiled with
the flag PKCS7_INDEFINITE_ENCODING the old form is used.
[Steve Henson]
*) Added BIO_vprintf() and BIO_vsnprintf().
[Richard Levitte]
*) Added more prefixes to parse for in the the strings written
through a logging bio, to cover all the levels that are available
through syslog. The prefixes are now:
PANIC, EMERG, EMR => LOG_EMERG
ALERT, ALR => LOG_ALERT
CRIT, CRI => LOG_CRIT
ERROR, ERR => LOG_ERR
WARNING, WARN, WAR => LOG_WARNING
NOTICE, NOTE, NOT => LOG_NOTICE
INFO, INF => LOG_INFO
DEBUG, DBG => LOG_DEBUG
and as before, if none of those prefixes are present at the
beginning of the string, LOG_ERR is chosen.
On Win32, the LOG_* levels are mapped according to this:
LOG_EMERG, LOG_ALERT, LOG_CRIT, LOG_ERR => EVENTLOG_ERROR_TYPE
LOG_WARNING => EVENTLOG_WARNING_TYPE
LOG_NOTICE, LOG_INFO, LOG_DEBUG => EVENTLOG_INFORMATION_TYPE
[Richard Levitte]
*) Made it possible to reconfigure with just the configuration
argument "reconf" or "reconfigure". The command line arguments
are stored in Makefile.ssl in the variable CONFIGURE_ARGS,
and are retrieved from there when reconfiguring.

*) MD4 implemented.
[Assar Westerlund <assar@sics.se>, Richard Levitte]

*) Add the arguments -CAfile and -CApath to the pkcs12 utility.
[Richard Levitte]
*) The obj_dat.pl script was messing up the sorting of object
names. The reason was that it compared the quoted version
of strings as a result "OCSP" > "OCSP Signing" because
" > SPACE. Changed script to store unquoted versions of
names and add quotes on output. It was also omitting some
names from the lookup table if they were given a default
value (that is if SN is missing it is given the same
value as LN and vice versa), these are now added on the
grounds that if an object has a name we should be able to
look it up. Finally added warning output when duplicate
short or long names are found.

*) Changes needed for Tandem NSK.

*) Fix SSL 2.0 rollback checking: Due to an off-by-one error in
RSA_padding_check_SSLv23(), special padding was never detected
and thus the SSL 3.0/TLS 1.0 countermeasure against protocol
version rollback attacks was not effective.
In s23_clnt.c, don't use special rollback-attack detection padding
(RSA_SSLV23_PADDING) if SSL 2.0 is the only protocol enabled in the
client; similarly, in s23_srvr.c, don't do the rollback check if
SSL 2.0 is the only protocol enabled in the server.
[Bodo Moeller]
*) Make it possible to get hexdumps of unprintable data with 'openssl
asn1parse'. By implication, the functions ASN1_parse_dump() and
BIO_dump_indent() are added.
[Richard Levitte]
*) New functions ASN1_STRING_print_ex() and X509_NAME_print_ex()
these print out strings and name structures based on various
flags including RFC2253 support and proper handling of
multibyte characters. Added options to the 'x509' utility
to allow the various flags to be set.
[Steve Henson]
*) Various fixes to use ASN1_TIME instead of ASN1_UTCTIME.
Also change the functions X509_cmp_current_time() and
X509_gmtime_adj() work with an ASN1_TIME structure,
this will enable certificates using GeneralizedTime in validity
dates to be checked.
[Steve Henson]
*) Make the NEG_PUBKEY_BUG code (which tolerates invalid
negative public key encodings) on by default,
NO_NEG_PUBKEY_BUG can be set to disable it.
[Steve Henson]
*) New function c2i_ASN1_OBJECT() which acts on ASN1_OBJECT
content octets. An i2c_ASN1_OBJECT is unnecessary because
the encoding can be trivially obtained from the structure.
[Steve Henson]
*) crypto/err.c locking bugfix: Use write locks (CRYPTO_w_[un]lock),
not read locks (CRYPTO_r_[un]lock).
[Bodo Moeller]
*) A first attempt at creating official support for shared
libraries through configuration. I've kept it so the
default is static libraries only, and the OpenSSL programs
are always statically linked for now, but there are
preparations for dynamic linking in place.
This has been tested on Linux and True64.
[Richard Levitte]
*) Randomness polling function for Win9x, as described in:
Peter Gutmann, Software Generation of Practically Strong
Random Numbers.
[Ulf Möller]
*) Fix so PRNG is seeded in req if using an already existing
DSA key.
[Steve Henson]
*) New options to smime application. -inform and -outform
allow alternative formats for the S/MIME message including
PEM and DER. The -content option allows the content to be
specified separately. This should allow things like Netscape
form signing output easier to verify.
[Steve Henson]
*) Fix the ASN1 encoding of tags using the 'long form'.
[Steve Henson]
*) New ASN1 functions, i2c_* and c2i_* for INTEGER and BIT
STRING types. These convert content octets to and from the
underlying type. The actual tag and length octets are
already assumed to have been read in and checked. These
are needed because all other string types have virtually
identical handling apart from the tag. By having versions
of the ASN1 functions that just operate on content octets
IMPLICIT tagging can be handled properly. It also allows
the ASN1_ENUMERATED code to be cut down because ASN1_ENUMERATED
and ASN1_INTEGER are identical apart from the tag.
[Steve Henson]
*) Change the handling of OID objects as follows:
- New object identifiers are inserted in objects.txt, following
the syntax given in objects.README.
- objects.pl is used to process obj_mac.num and create a new
obj_mac.h.
- obj_dat.pl is used to create a new obj_dat.h, using the data in
