_______________
*) Add SRP support.
[Tom Wu <tjw@cs.stanford.edu> and Ben Laurie]
*) Add functions to copy EVP_PKEY_METHOD and retrieve flags and id.
[Steve Henson]
*) Add EC_GFp_nistp224_method(), a 64-bit optimized implementation for
elliptic curve NIST-P224 with constant-time single point multiplication on
typical inputs. EC_GROUP_new_by_curve_name() will automatically use this
(while EC_GROUP_new_curve_GFp() currently won't and prefers the more
flexible implementations).
The implementation requires support for the nonstandard type __uint128_t,
and so is disabled by default. To include this in your build of OpenSSL,
use -DEC_NISTP224_64_GCC_128 on the Configure (or config) command line,
and run "make depend" (or "make update").
[Emilia Käsper <emilia.kasper@esat.kuleuven.be> (Google)]
*) Permit abbreviated handshakes when renegotiating using the function
SSL_renegotiate_abbreviated().
[Robin Seggelmann <seggelmann@fh-muenster.de>]
Dr. Stephen Henson
committed
*) Add call to ENGINE_register_all_complete() to
ENGINE_load_builtin_engines(), so some implementations get used
automatically instead of needing explicit application support.
[Steve Henson]
*) Add support for TLS key exporter as described in RFC5705.
[Robin Seggelmann <seggelmann@fh-muenster.de>, Steve Henson]
*) Initial TLSv1.1 support. Since TLSv1.1 is very similar to TLS v1.0 only
a few changes are required:
Add SSL_OP_NO_TLSv1_1 flag.
Add TLSv1_1 methods.
Update version checking logic to handle version 1.1.
Add explicit IV handling (ported from DTLS code).
Add command line options to s_client/s_server.

Changes between 1.0.0c and 1.0.0d [8 Feb 2011]
*) Fix parsing of OCSP stapling ClientHello extension. CVE-2011-0014
[Neel Mehta, Adam Langley, Bodo Moeller (Google)]
*) Fix bug in string printing code: if *any* escaping is enabled we must
escape the escape character (backslash) or the resulting string is
ambiguous.
[Steve Henson]
Changes between 1.0.0b and 1.0.0c [2 Dec 2010]
*) Disable code workaround for ancient and obsolete Netscape browsers
and servers: an attacker can use it in a ciphersuite downgrade attack.
Thanks to Martin Rex for discovering this bug. CVE-2010-4180
[Steve Henson]
*) Fixed J-PAKE implementation error, originally discovered by
Sebastien Martini, further info and confirmation from Stefan
Arentz and Feng Hao. Note that this fix is a security fix. CVE-2010-4252
[Ben Laurie]
Changes between 1.0.0a and 1.0.0b [16 Nov 2010]
*) Fix extension code to avoid race conditions which can result in a buffer
overrun vulnerability: resumed sessions must not be modified as they can
be shared by multiple threads. CVE-2010-3864
*) Fix WIN32 build system to correctly link an ENGINE directory into
a DLL.
[Steve Henson]
*) Check return value of int_rsa_verify in pkey_rsa_verifyrecover
(CVE-2010-1633)
[Steve Henson, Peter-Michael Hager <hager@dortmund.net>]
Changes between 0.9.8n and 1.0.0 [29 Mar 2010]
Dr. Stephen Henson
committed
*) Add "missing" function EVP_CIPHER_CTX_copy(). This copies a cipher
context. The operation can be customised via the ctrl mechanism in
case ENGINEs want to include additional functionality.
[Steve Henson]
*) Tolerate yet another broken PKCS#8 key format: private key value negative.
[Steve Henson]
*) Add new -subject_hash_old and -issuer_hash_old options to x509 utility to
output hashes compatible with older versions of OpenSSL.
[Willy Weisz <weisz@vcpc.univie.ac.at>]
*) Fix compression algorithm handling: if resuming a session use the
compression algorithm of the resumed session instead of determining
it from client hello again. Don't allow server to change algorithm.

*) Add load_crls() function to apps tidying load_certs() too. Add option
to verify utility to allow additional CRLs to be included.
[Steve Henson]
*) Update OCSP request code to permit adding custom headers to the request:
some responders need this.
[Steve Henson]
*) The function EVP_PKEY_sign() returns <=0 on error: check return code
correctly.
[Julia Lawall <julia@diku.dk>]
Dr. Stephen Henson
committed
*) Update verify callback code in apps/s_cb.c and apps/verify.c, it
needlessly dereferenced structures, used obsolete functions and
didn't handle all updated verify codes correctly.
[Steve Henson]
*) Disable MD2 in the default configuration.
*) In BIO_pop() and BIO_push() use the ctrl argument (which was NULL) to
indicate the initial BIO being pushed or popped. This makes it possible
to determine whether the BIO is the one explicitly called or as a result
of the ctrl being passed down the chain. Fix BIO_pop() and SSL BIOs so
it handles reference counts correctly and doesn't zero out the I/O bio
when it is not being explicitly popped. WARNING: applications which
included workarounds for the old buggy behaviour will need to be modified
or they could free up already freed BIOs.
[Steve Henson]
*) Extend the uni2asc/asc2uni => OPENSSL_uni2asc/OPENSSL_asc2uni
renaming to all platforms (within the 0.9.8 branch, this was
done conditionally on Netware platforms to avoid a name clash).
*) Add ECDHE and PSK support to DTLS.
[Michael Tuexen <tuexen@fh-muenster.de>]
*) Add CHECKED_STACK_OF macro to safestack.h, otherwise safestack can't
be used on C++.
[Steve Henson]
*) Add "missing" function EVP_MD_flags() (without this the only way to
retrieve a digest flags is by accessing the structure directly. Update
EVP_MD_do_all*() and EVP_CIPHER_do_all*() to include the name a digest
or cipher is registered as in the "from" argument. Print out all
registered digests in the dgst usage message instead of manually
attempting to work them out.
[Steve Henson]
Dr. Stephen Henson
committed
*) If no SSLv2 ciphers are used don't use an SSLv2 compatible client hello:
this allows the use of compression and extensions. Change default cipher
string to remove SSLv2 ciphersuites. This effectively avoids ancient SSLv2
by default unless an application cipher string requests it.
[Steve Henson]
Dr. Stephen Henson
committed
*) Alter match criteria in PKCS12_parse(). It used to try to use local
key ids to find matching certificates and keys but some PKCS#12 files
don't follow the (somewhat unwritten) rules and this strategy fails.
Now just gather all certificates together and the first private key
then look for the first certificate that matches the key.
[Steve Henson]
Dr. Stephen Henson
committed
*) Support use of registered digest and cipher names for dgst and cipher
commands instead of having to add each one as a special case. So now
you can do:
openssl sha256 foo
as well as:
openssl dgst -sha256 foo
and this works for ENGINE based algorithms too.
[Steve Henson]
*) Update Gost ENGINE to support parameter files.
[Victor B. Wagner <vitus@cryptocom.ru>]
*) Support GeneralizedTime in ca utility.
[Oliver Martin <oliver@volatilevoid.net>, Steve Henson]
*) Enhance the hash format used for certificate directory links. The new
form uses the canonical encoding (meaning equivalent names will work
even if they aren't identical) and uses SHA1 instead of MD5. This form
is incompatible with the older format and as a result c_rehash should
be used to rebuild symbolic links.
[Steve Henson]
*) Make PKCS#8 the default write format for private keys, replacing the
traditional format. This form is standardised, more secure and doesn't
include an implicit MD5 dependency.
[Steve Henson]
*) Add a $gcc_devteam_warn option to Configure. The idea is that any code
