Changes between 0.9.8e and 0.9.9 [xx XXX xxxx]
*) Initial incomplete changes to avoid need for function casts in OpenSSL
when OPENSSL_NO_FCAST is set: some compilers (gcc 4.2 and later) reject
their use. Safestack is reimplemented using inline functions: tests show
that these calls are typically optimized away by compilers so they have
no additional overhead. Update ASN1 to avoid use of legacy functions.
[Steve Henson]
*) Win32/64 targets are linked with Winsock2.
[Andy Polyakov]
*) Add an X509_CRL_METHOD structure to allow CRL processing to be redirected
to external functions. This can be used to increase CRL handling
efficiency especially when CRLs are very large by (for example) storing
the CRL revoked certificates in a database.
[Steve Henson]
*) Overhaul of by_dir code. Add support for dynamic loading of CRLs so
new CRLs added to a directory can be used. New command line option
-verify_return_error to s_client and s_server. This causes real errors
to be returned by the verify callback instead of carrying on no matter
what. This reflects the way a "real world" verify callback would behave.
[Steve Henson]
*) GOST engine, supporting several GOST algorithms and public key formats.
Kindly donated by Cryptocom.
[Cryptocom]
*) Partial support for Issuing Distribution Point CRL extension. CRLs
partitioned by DP are handled but no indirect CRL or reason partitioning
(yet). Complete overhaul of CRL handling: now the most suitable CRL is
selected via a scoring technique which handles IDP and AKID in CRLs.
[Steve Henson]
*) New X509_STORE_CTX callbacks lookup_crls() and lookup_certs() which
will ultimately be used for all verify operations: this will remove the
X509_STORE dependency on certificate verification and allow alternative
lookup methods. X509_STORE based implementations of these two callbacks.
[Steve Henson]
*) Allow multiple CRLs to exist in an X509_STORE with matching issuer names.
Modify get_crl() to find a valid (unexpired) CRL if possible.
[Steve Henson]
*) New function X509_CRL_match() to check if two CRLs are identical. Normally
this would be called X509_CRL_cmp() but that name is already used by
a function that just compares CRL issuer names. Cache several CRL
extensions in X509_CRL structure and cache CRLDP in X509.

*) Store a "canonical" representation of X509_NAME structure (ASN1 Name)
this maps equivalent X509_NAME structures into a consistent structure.
Name comparison can then be performed rapidly using memcmp().
[Steve Henson]
*) Non-blocking OCSP request processing. Add -timeout option to ocsp
utility.
*) Allow digests to supply their own micalg string for S/MIME type using
the ctrl EVP_MD_CTRL_MICALG.
[Steve Henson]
*) During PKCS7 signing pass the PKCS7 SignerInfo structure to the
EVP_PKEY_METHOD before and after signing via the EVP_PKEY_CTRL_PKCS7_SIGN
ctrl. It can then customise the structure before and/or after signing
if necessary.
[Steve Henson]
*) New function OBJ_add_sigid() to allow application defined signature OIDs
to be added to OpenSSLs internal tables. New function OBJ_sigid_free()
to free up any added signature OIDs.
[Steve Henson]
*) New functions EVP_CIPHER_do_all(), EVP_CIPHER_do_all_sorted(),
EVP_MD_do_all() and EVP_MD_do_all_sorted() to enumerate internal
digest and cipher tables. New options added to openssl utility:
list-message-digest-algorithms and list-cipher-algorithms.
[Steve Henson]
*) In addition to the numerical (unsigned long) thread ID, provide
for a pointer (void *) thread ID. This helps accomodate systems
that do not provide an unsigned long thread ID. OpenSSL assumes
it is in the same thread iff both the numerical and the pointer
thread ID agree; so applications are just required to define one
of them appropriately (e.g., by using a pointer to a per-thread
memory object malloc()ed by the application for the pointer-type
thread ID). Exactly analoguous to the existing functions
void CRYPTO_set_id_callback(unsigned long (*func)(void));
unsigned long (*CRYPTO_get_id_callback(void))(void);
unsigned long CRYPTO_thread_id(void);
we now have additional functions
void CRYPTO_set_idptr_callback(void *(*func)(void));
void *(*CRYPTO_get_idptr_callback(void))(void);
void *CRYPTO_thread_idptr(void);
also in <openssl/crypto.h>. The default value for
CRYPTO_thread_idptr() if the application has not provided its own
callback is &errno.
[Bodo Moeller]
*) Change the array representation of binary polynomials: the list
of degrees of non-zero coefficients is now terminated with -1.
Previously it was terminated with 0, which was also part of the
value; thus, the array representation was not applicable to
polynomials where t^0 has coefficient zero. This change makes
the array representation useful in a more general context.

*) Various modifications and fixes to SSL/TLS cipher string
handling. For ECC, the code now distinguishes between fixed ECDH
with RSA certificates on the one hand and with ECDSA certificates
on the other hand, since these are separate ciphersuites. The
unused code for Fortezza ciphersuites has been removed.
For consistency with EDH, ephemeral ECDH is now called "EECDH"
(not "ECDHE"). For consistency with the code for DH
certificates, use of ECDH certificates is now considered ECDH
authentication, not RSA or ECDSA authentication (the latter is
merely the CA's signing algorithm and not actively used in the
protocol).
The temporary ciphersuite alias "ECCdraft" is no longer
available, and ECC ciphersuites are no longer excluded from "ALL"
and "DEFAULT". The following aliases now exist for RFC 4492
ciphersuites, most of these by analogy with the DH case:
kECDHr - ECDH cert, signed with RSA
kECDHe - ECDH cert, signed with ECDSA
kECDH - ECDH cert (signed with either RSA or ECDSA)
kEECDH - ephemeral ECDH
ECDH - ECDH cert or ephemeral ECDH
aECDH - ECDH cert
aECDSA - ECDSA cert
ECDSA - ECDSA cert
AECDH - anonymous ECDH
EECDH - non-anonymous ephemeral ECDH (equivalent to "kEECDH:-AECDH")

*) Add additional S/MIME capabilities for AES and GOST ciphers if supported.
Use correct micalg parameters depending on digest(s) in signed message.
[Steve Henson]
*) Add engine support for EVP_PKEY_ASN1_METHOD. Add functions to process
an ENGINE asn1 method. Support ENGINE lookups in the ASN1 code.
[Steve Henson]
*) Initial engine support for EVP_PKEY_METHOD. New functions to permit
an engine to register a method. Add ENGINE lookups for methods and
functional reference processing.
[Steve Henson]
*) New functions EVP_Digest{Sign,Verify)*. These are enchance versions of
EVP_{Sign,Verify}* which allow an application to customise the signature
process.
[Steve Henson]
*) New -resign option to smime utility. This adds one or more signers
to an existing PKCS#7 signedData structure. Also -md option to use an
alternative message digest algorithm for signing.
[Steve Henson]
*) Tidy up PKCS#7 routines and add new functions to make it easier to
create PKCS7 structures containing multiple signers. Update smime
application to support multiple signers.
[Steve Henson]
*) New -macalg option to pkcs12 utility to allow setting of an alternative
digest MAC.
[Steve Henson]
*) Initial support for PKCS#5 v2.0 PRFs other than default SHA1 HMAC.

Reorganize PBE internals to lookup from a static table using NIDs,
add support for HMAC PBE OID translation. Add a EVP_CIPHER ctrl:
EVP_CTRL_PBE_PRF_NID this allows a cipher to specify an alternative
PRF which will be automatically used with PBES2.
[Steve Henson]
*) Replace the algorithm specific calls to generate keys in "req" with the
new API.
[Steve Henson]
*) Update PKCS#7 enveloped data routines to use new API. This is now
supported by any public key method supporting the encrypt operation. A
ctrl is added to allow the public key algorithm to examine or modify
the PKCS#7 RecipientInfo structure if it needs to: for RSA this is
a no op.
