*) If a candidate issuer certificate is already part of the constructed
path ignore it: new debug notification X509_V_ERR_PATH_LOOP for this case.
[Steve Henson]
*) Improve forward-security support: add functions
void SSL_CTX_set_not_resumable_session_callback(SSL_CTX *ctx, int (*cb)(SSL *ssl, int is_forward_secure))
void SSL_set_not_resumable_session_callback(SSL *ssl, int (*cb)(SSL *ssl, int is_forward_secure))
for use by SSL/TLS servers; the callback function will be called whenever a
new session is created, and gets to decide whether the session may be
cached to make it resumable (return 0) or not (return 1). (As by the
SSL/TLS protocol specifications, the session_id sent by the server will be
empty to indicate that the session is not resumable; also, the server will
not generate RFC 4507 (RFC 5077) session tickets.)
A simple reasonable callback implementation is to return is_forward_secure.
This parameter will be set to 1 or 0 depending on the ciphersuite selected
by the SSL/TLS server library, indicating whether it can provide forward
security.

*) Add Next Protocol Negotiation,
http://tools.ietf.org/html/draft-agl-tls-nextprotoneg-00. Can be
disabled with a no-npn flag to config or Configure. Code donated
by Google.
[Adam Langley <agl@google.com> and Ben Laurie]
*) Use type ossl_ssize_t instad of ssize_t which isn't available on
all platforms. Move ssize_t definition from e_os.h to the public
header file e_os2.h as it now appears in public header file cms.h
[Steve Henson]
*) New function OPENSSL_gmtime_diff to find the difference in days
and seconds between two tm structures. This will be used to provide
additional functionality for ASN1_TIME.
[Steve Henson]
*) New -sigopt option to the ca, req and x509 utilities. Additional
signature parameters can be passed using this option and in
*) Add RSA PSS signing function. This will generate and set the
appropriate AlgorithmIdentifiers for PSS based on those in the
corresponding EVP_MD_CTX structure. No application support yet.
[Steve Henson]
*) Support for companion algorithm specific ASN1 signing routines.
New function ASN1_item_sign_ctx() signs a pre-initialised
EVP_MD_CTX structure and sets AlgorithmIdentifiers based on
the appropriate parameters.
[Steve Henson]
*) Add new algorithm specific ASN1 verification initialisation function
to EVP_PKEY_ASN1_METHOD: this is not in EVP_PKEY_METHOD since the ASN1
handling will be the same no matter what EVP_PKEY_METHOD is used.
Add a PSS handler to support verification of PSS signatures: checked
against a number of sample certificates.
[Steve Henson]
*) Add signature printing for PSS. Add PSS OIDs.

*) Add algorithm specific signature printing. An individual ASN1 method
can now print out signatures instead of the standard hex dump.
More complex signatures (e.g. PSS) can print out more meaningful
information. Include DSA version that prints out the signature
parameters r, s.

*) Add -trusted_first option which attempts to find certificates in the
trusted store even if an untrusted chain is also supplied.

*) Initial experimental support for explicitly trusted non-root CAs.
OpenSSL still tries to build a complete chain to a root but if an
intermediate CA has a trust setting included that is used. The first
setting is used: whether to trust or reject.
[Steve Henson]
*) New -verify_name option in command line utilities to set verification
parameters by name.
[Steve Henson]
*) Initial CMAC implementation. WARNING: EXPERIMENTAL, API MAY CHANGE.
Add CMAC pkey methods.
*) Experiemental regnegotiation in s_server -www mode. If the client

[Steve Henson]
*) Add an "external" session cache for debugging purposes to s_server. This
should help trace issues which normally are only apparent in deployed
multi-process servers.
[Steve Henson]
*) Experiemental password based recipient info support for CMS library:
implementing RFC3211.
[Steve Henson]

committed
*) Split password based encryption into PBES2 and PBKDF2 functions. This
neatly separates the code into cipher and PBE sections and is required
for some algorithms that split PBES2 into separate pieces (such as
password based CMS).
*) Extensive audit of libcrypto with DEBUG_UNUSED. Fix many cases where
return value is ignored. NB. The functions RAND_add(), RAND_seed(),
BIO_set_cipher() and some obscure PEM functions were changed so they
can now return an error. The RAND changes required a change to the
RAND_METHOD structure.

committed
*) New macro __owur for "OpenSSL Warn Unused Result". This makes use of
a gcc attribute to warn if the result of a function is ignored. This
is enable if DEBUG_UNUSED is set. Add to several functions in evp.h
whose return value is often ignored.
[Steve Henson]
Changes between 1.0.0c and 1.0.1 [xx XXX xxxx]
*) 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>]

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.
[Steve Henson]
Changes between 1.0.0c and 1.0.0d [xx XXX xxxx]
*) 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]
*) 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]
Changes between 1.0.0 and 1.0.0a [01 Jun 2010]
*) Check return value of int_rsa_verify in pkey_rsa_verifyrecover
(CVE-2010-1633)
