*) Add ECDH code to fips module and fips_ecdhvs for primitives only testing.
[Steve Henson]
*) New algorithm test program fips_dhvs to handle DH primitives only testing.
[Steve Henson]
*) New function DH_compute_key_padded() to compute a DH key and pad with
leading zeroes if needed: this complies with SP800-56A et al.
[Steve Henson]
*) Initial implementation of SP800-90 DRBGs for Hash and CTR. Not used by
anything, incomplete, subject to change and largely untested at present.
[Steve Henson]
*) Modify fipscanisteronly build option to only build the necessary object
files by filtering FIPS_EX_OBJ through a perl script in crypto/Makefile.
[Steve Henson]
*) Add experimental option FIPSSYMS to give all symbols in
fipscanister.o and FIPS or fips prefix. This will avoid
conflicts with future versions of OpenSSL. Add perl script
util/fipsas.pl to preprocess assembly language source files
and rename any affected symbols.
*) Add selftest checks and algorithm block of non-fips algorithms in
FIPS mode. Remove DES2 from selftests.
[Steve Henson]
Dr. Stephen Henson
committed
*) Add ECDSA code to fips module. Add tiny fips_ecdsa_check to just
return internal method without any ENGINE dependencies. Add new
tiny fips sign and verify functions.

[Steve Henson]
*) New build option no-ec2m to disable characteristic 2 code.
[Steve Henson]
*) New build option "fipscanisteronly". This only builds fipscanister.o
and (currently) associated fips utilities. Uses the file Makefile.fips
instead of Makefile.org as the prototype.

*) Add some FIPS mode restrictions to GCM. Add internal IV generator.
Update fips_gcmtest to use IV generator.
[Steve Henson]
Dr. Stephen Henson
committed
*) Initial, experimental EVP support for AES-GCM. AAD can be input by
setting output buffer to NULL. The *Final function must be
called although it will not retrieve any additional data. The tag
can be set or retrieved with a ctrl. The IV length is by default 12
bytes (96 bits) but can be set to an alternative value. If the IV
length exceeds the maximum IV length (currently 16 bytes) it cannot be
set before the key.

*) New flag in ciphers: EVP_CIPH_FLAG_CUSTOM_CIPHER. This means the
underlying do_cipher function handles all cipher semantics itself
including padding and finalisation. This is useful if (for example)
an ENGINE cipher handles block padding itself. The behaviour of
do_cipher is subtly changed if this flag is set: the return value
is the number of characters written to the output buffer (zero is
no longer an error code) or a negative error code. Also if the
Dr. Stephen Henson

input buffer is NULL and length 0 finalisation should be performed.

[Steve Henson]
*) 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.
[Emilia Käsper <emilia.kasper@esat.kuleuven.be> (Google)]
*) 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.
[Steve Henson]
Dr. Stephen Henson
committed
*) 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

browses /reneg connection is renegotiated. If /renegcert it is
[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]
Dr. Stephen 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.
[Steve Henson]
Dr. Stephen Henson
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]
*) Add functions to copy EVP_PKEY_METHOD and retrieve flags and id.
