Changes between 0.9.8b and 0.9.9 [xx XXX xxxx]
*) 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.

*) 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.

*) 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.
[Douglas Stebila]
*) 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.
[Steve Henson]
*) Add a ctrl to asn1 method to allow a public key algorithm to express
a default digest type to use. In most cases this will be SHA1 but some
algorithms (such as GOST) need to specify an alternative digest. The
return value indicates how strong the prefernce is 1 means optional and
2 is mandatory (that is it is the only supported type). Modify
ASN1_item_sign() to accept a NULL digest argument to indicate it should
use the default md. Update openssl utilities to use the default digest
type for signing if it is not explicitly indicated.
[Steve Henson]
*) Use OID cross reference table in ASN1_sign() and ASN1_verify(). New
EVP_MD flag EVP_MD_FLAG_PKEY_METHOD_SIGNATURE. This uses the relevant
signing method from the key type. This effectively removes the link
between digests and public key types.
[Steve Henson]
*) Add an OID cross reference table and utility functions. Its purpose is to
translate between signature OIDs such as SHA1WithrsaEncryption and SHA1,
rsaEncryption. This will allow some of the algorithm specific hackery
needed to use the correct OID to be removed.
[Steve Henson]
*) Remove algorithm specific dependencies when setting PKCS7_SIGNER_INFO
structures for PKCS7_sign(). They are now set up by the relevant public
key ASN1 method.
[Steve Henson]
*) Add provisional EC pkey method with support for ECDSA and ECDH.
[Steve Henson]
*) Add support for key derivation (agreement) in the API, DH method and
pkeyutl.
[Steve Henson]
*) Add DSA pkey method and DH pkey methods, extend DH ASN1 method to support
public and private key formats. As a side effect these add additional
command line functionality not previously available: DSA signatures can be
generated and verified using pkeyutl and DH key support and generation in
pkey, genpkey.
[Steve Henson]
*) BeOS support.
[Oliver Tappe <zooey@hirschkaefer.de>]
*) New make target "install_html_docs" installs HTML renditions of the
manual pages.
[Oliver Tappe <zooey@hirschkaefer.de>]
*) New utility "genpkey" this is analagous to "genrsa" etc except it can
generate keys for any algorithm. Extend and update EVP_PKEY_METHOD to
support key and parameter generation and add initial key generation
functionality for RSA.
[Steve Henson]
*) Add functions for main EVP_PKEY_method operations. The undocumented
functions EVP_PKEY_{encrypt,decrypt} have been renamed to
EVP_PKEY_{encrypt,decrypt}_old.

*) Initial definitions for EVP_PKEY_METHOD. This will be a high level public
key API, doesn't do much yet.
[Steve Henson]
Dr. Stephen Henson
committed
*) New function EVP_PKEY_asn1_get0_info() to retrieve information about
public key algorithms. New option to openssl utility:
"list-public-key-algorithms" to print out info.
[Steve Henson]
*) Implement the Supported Elliptic Curves Extension for
ECC ciphersuites from draft-ietf-tls-ecc-12.txt.
[Douglas Stebila]
*) Don't free up OIDs in OBJ_cleanup() if they are in use by EVP_MD or
