Changes between 0.9.5a and 0.9.6 [xx XXX 2000]
*) Avoid 'thread_hash' memory leak in crypto/err/err.c by freeing
it in ERR_remove_state if appropriate, and change ERR_get_state
accordingly to avoid race conditions (this is necessary because
thread_hash is no longer constant once set).

*) RSA_get_default_method() will now cause a default
RSA_METHOD to be chosen if one doesn't exist already.
Previously this was only set during a call to RSA_new()
or RSA_new_method(NULL) meaning it was possible for
RSA_get_default_method() to return NULL.
[Geoff Thorpe]
*) Added native name translation to the existing DSO code
that will convert (if the flag to do so is set) filenames
that are sufficiently small and have no path information
into a canonical native form. Eg. "blah" converted to
"libblah.so" or "blah.dll" etc.
[Geoff Thorpe]
*) New function ERR_error_string_n(e, buf, len) which is like
ERR_error_string(e, buf), but writes at most 'len' bytes
including the 0 terminator. For ERR_error_string_n, 'buf'
may not be NULL.
[Damien Miller <djm@mindrot.org>, Bodo Moeller]
*) CONF library reworked to become more general. A new CONF
configuration file reader "class" is implemented as well as a
new functions (NCONF_*, for "New CONF") to handle it. The now
old CONF_* functions are still there, but are reimplemented to
work in terms of the new functions. Also, a set of functions
to handle the internal storage of the configuration data is
provided to make it easier to write new configuration file
reader "classes" (I can definitely see something reading a
configuration file in XML format, for example), called _CONF_*,
or "the configuration storage API"...
The new configuration file reading functions are:
NCONF_new, NCONF_free, NCONF_load, NCONF_load_fp, NCONF_load_bio,
NCONF_get_section, NCONF_get_string, NCONF_get_numbre
NCONF_default, NCONF_WIN32
NCONF_dump_fp, NCONF_dump_bio
NCONF_default and NCONF_WIN32 are method (or "class") choosers,
NCONF_new creates a new CONF object. This works in the same way
as other interfaces in OpenSSL, like the BIO interface.
NCONF_dump_* dump the internal storage of the configuration file,
which is useful for debugging. All other functions take the same
arguments as the old CONF_* functions wth the exception of the
first that must be a `CONF *' instead of a `LHASH *'.
To make it easer to use the new classes with the old CONF_* functions,
the function CONF_set_default_method is provided.

*) Add '-tls1' option to 'openssl ciphers', which was already
mentioned in the documentation but had not been implemented.
(This option is not yet really useful because even the additional
experimental TLS 1.0 ciphers are currently treated as SSL 3.0 ciphers.)
[Bodo Moeller]
*) Initial DSO code added into libcrypto for letting OpenSSL (and
OpenSSL-based applications) load shared libraries and bind to
them in a portable way.
[Geoff Thorpe, with contributions from Richard Levitte]
Changes between 0.9.5 and 0.9.5a [1 Apr 2000]
*) Make sure _lrotl and _lrotr are only used with MSVC.
*) Use lock CRYPTO_LOCK_RAND correctly in ssleay_rand_status
(the default implementation of RAND_status).
*) Rename openssl x509 option '-crlext', which was added in 0.9.5,
to '-clrext' (= clear extensions), as intended and documented.
[Bodo Moeller; inconsistency pointed out by Michael Attili
<attili@amaxo.com>]
*) Fix for HMAC. It wasn't zeroing the rest of the block if the key length
was larger than the MD block size.
[Steve Henson, pointed out by Yost William <YostW@tce.com>]
*) Modernise PKCS12_parse() so it uses STACK_OF(X509) for its ca argument
fix a leak when the ca argument was passed as NULL. Stop X509_PUBKEY_set()
using the passed key: if the passed key was a private key the result
of X509_print(), for example, would be to print out all the private key
components.
[Steve Henson]
*) des_quad_cksum() byte order bug fix.
[Ulf Möller, using the problem description in krb4-0.9.7, where
the solution is attributed to Derrick J Brashear <shadow@DEMENTIA.ORG>]
*) Fix so V_ASN1_APP_CHOOSE works again: however its use is strongly
discouraged.
[Steve Henson, pointed out by Brian Korver <briank@cs.stanford.edu>]
*) For easily testing in shell scripts whether some command
'openssl XXX' exists, the new pseudo-command 'openssl no-XXX'
returns with exit code 0 iff no command of the given name is available.
'no-XXX' is printed in this case, 'XXX' otherwise. In both cases,
the output goes to stdout and nothing is printed to stderr.
Additional arguments are always ignored.
Since for each cipher there is a command of the same name,
the 'no-cipher' compilation switches can be tested this way.
('openssl no-XXX' is not able to detect pseudo-commands such
as 'quit', 'list-XXX-commands', or 'no-XXX' itself.)
[Bodo Moeller]
*) Update test suite so that 'make test' succeeds in 'no-rsa' configuration.
[Bodo Moeller]
*) For SSL_[CTX_]set_tmp_dh, don't create a DH key if SSL_OP_SINGLE_DH_USE
is set; it will be thrown away anyway because each handshake creates
its own key.
ssl_cert_dup, which is used by SSL_new, now copies DH keys in addition
to parameters -- in previous versions (since OpenSSL 0.9.3) the
'default key' from SSL_CTX_set_tmp_dh would always be lost, meanining
you effectivly got SSL_OP_SINGLE_DH_USE when using this macro.
[Bodo Moeller]
*) New s_client option -ign_eof: EOF at stdin is ignored, and
'Q' and 'R' lose their special meanings (quit/renegotiate).
This is part of what -quiet does; unlike -quiet, -ign_eof
does not suppress any output.
[Richard Levitte]
purpose X509_PURPOSE_ANY is "any purpose" which automatically
accepts a certificate or CA, this was the previous behaviour,
with all the associated security issues.
X509_TRUST_COMPAT is the old trust behaviour: only and
automatically trust self signed roots in certificate store. A
new trust setting X509_TRUST_DEFAULT is used to specify that
a purpose has no associated trust setting and it should instead
use the value in the default purpose.
[Steve Henson]
*) Fix the PKCS#8 DSA private key code so it decodes keys again
and fix a memory leak.
[Steve Henson]
*) In util/mkerr.pl (which implements 'make errors'), preserve
reason strings from the previous version of the .c file, as
the default to have only downcase letters (and digits) in
automatically generated reasons codes is not always appropriate.
[Bodo Moeller]
*) In ERR_load_ERR_strings(), build an ERR_LIB_SYS error reason table
using strerror. Previously, ERR_reason_error_string() returned
library names as reason strings for SYSerr; but SYSerr is a special
case where small numbers are errno values, not library numbers.
[Bodo Moeller]
*) Add '-dsaparam' option to 'openssl dhparam' application. This
converts DSA parameters into DH parameters. (When creating parameters,
DSA_generate_parameters is used.)
[Bodo Moeller]
*) Include 'length' (recommended exponent length) in C code generated
by 'openssl dhparam -C'.
[Bodo Moeller]
*) The second argument to set_label in perlasm was already being used
so couldn't be used as a "file scope" flag. Moved to third argument
which was free.
[Steve Henson]
*) In PEM_ASN1_write_bio and some other functions, use RAND_pseudo_bytes
instead of RAND_bytes for encryption IVs and salts.
[Bodo Moeller]
*) Include RAND_status() into RAND_METHOD instead of implementing
it only for md_rand.c Otherwise replacing the PRNG by calling
RAND_set_rand_method would be impossible.
[Bodo Moeller]
*) Don't let DSA_generate_key() enter an infinite loop if the random
number generation fails.
[Bodo Moeller]
*) New 'rand' application for creating pseudo-random output.
[Bodo Moeller]
*) Added configuration support for Linux/IA64
