Changes between 0.9.8n and 1.0.0 [29 Mar 2010]

*) 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@xxxxx>]

*) 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.
[Steve Henson]

*) 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@xxxxx>]

*) 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.
[Steve Henson]

*) 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).
[Guenter <lists@xxxxx>]

*) Add ECDHE and PSK support to DTLS.
[Michael Tuexen <tuexen@xxxxx>]

*) 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]

*) 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]

*) 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]

*) 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@xxxxx>]

*) Support GeneralizedTime in ca utility.
[Oliver Martin <oliver@xxxxx>, 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
committed to OpenSSL should pass this lot as a minimum.
[Steve Henson]

*) Add session ticket override functionality for use by EAP-FAST.
[Jouni Malinen <j@xxxxx>]

*) Modify HMAC functions to return a value. Since these can be implemented
in an ENGINE errors can occur.
[Steve Henson]

*) Type-checked OBJ_bsearch_ex.
[Ben Laurie]

*) Type-checked OBJ_bsearch. Also some constification necessitated
by type-checking. Still to come: TXT_DB, bsearch(?),
OBJ_bsearch_ex, qsort, CRYPTO_EX_DATA, ASN1_VALUE, ASN1_STRING,
CONF_VALUE.
[Ben Laurie]

*) New function OPENSSL_gmtime_adj() to add a specific number of days and
seconds to a tm structure directly, instead of going through OS
specific date routines. This avoids any issues with OS routines such
as the year 2038 bug. New *_adj() functions for ASN1 time structures
and X509_time_adj_ex() to cover the extended range. The existing
X509_time_adj() is still usable and will no longer have any date issues.
[Steve Henson]

*) Delta CRL support. New use deltas option which will attempt to locate
and search any appropriate delta CRLs available.

This work was sponsored by Google.
[Steve Henson]

*) Support for CRLs partitioned by reason code. Reorganise CRL processing
code and add additional score elements. Validate alternate CRL paths
as part of the CRL checking and indicate a new error "CRL path validation
error" in this case. Applications wanting additional details can use
the verify callback and check the new "parent" field. If this is not
NULL CRL path validation is taking place. Existing applications wont
see this because it requires extended CRL support which is off by
default.

This work was sponsored by Google.
[Steve Henson]

*) Support for freshest CRL extension.

This work was sponsored by Google.
[Steve Henson]

*) Initial indirect CRL support. Currently only supported in the CRLs
passed directly and not via lookup. Process certificate issuer
CRL entry extension and lookup CRL entries by bother issuer name
and serial number. Check and process CRL issuer entry in IDP extension.

This work was sponsored by Google.
[Steve Henson]

*) Add support for distinct certificate and CRL paths. The CRL issuer
certificate is validated separately in this case. Only enabled if
an extended CRL support flag is set: this flag will enable additional
CRL functionality in future.

This work was sponsored by Google.
[Steve Henson]

*) Add support for policy mappings extension.

This work was sponsored by Google.
[Steve Henson]

*) Fixes to pathlength constraint, self issued certificate handling,
policy processing to align with RFC3280 and PKITS tests.

This work was sponsored by Google.
[Steve Henson]

*) Support for name constraints certificate extension. DN, email, DNS
and URI types are currently supported.

This work was sponsored by Google.
[Steve Henson]

*) To cater for systems that provide a pointer-based thread ID rather
than numeric, deprecate the current numeric thread ID mechanism and
replace it with a structure and associated callback type. This
mechanism allows a numeric "hash" to be extracted from a thread ID in
either case, and on platforms where pointers are larger than 'long',
mixing is done to help ensure the numeric 'hash' is usable even if it
can't be guaranteed unique. The default mechanism is to use "&errno"
as a pointer-based thread ID to distinguish between threads.

Applications that want to provide their own thread IDs should now use
CRYPTO_THREADID_set_callback() to register a callback that will call
either CRYPTO_THREADID_set_numeric() or CRYPTO_THREADID_set_pointer().

Note that ERR_remove_state() is now deprecated, because it is tied
to the assumption that thread IDs are numeric. ERR_remove_state(0)
to free the current thread's error state should be replaced by
ERR_remove_thread_state(NULL).

(This new approach replaces the functions CRYPTO_set_idptr_callback(),
CRYPTO_get_idptr_callback(), and CRYPTO_thread_idptr() that existed in
OpenSSL 0.9.9-dev between June 2006 and August 2008. Also, if an
application was previously providing a numeric thread callback that
was inappropriate for distinguishing threads, then uniqueness might
have been obtained with &errno that happened immediately in the
intermediate development versions of OpenSSL; this is no longer the
case, the numeric thread callback will now override the automatic use
of &errno.)
[Geoff Thorpe, with help from Bodo Moeller]

*) Initial support for different CRL issuing certificates. This covers a
simple case where the self issued certificates in the chain exist and
the real CRL issuer is higher in the existing chain.

This work was sponsored by Google.
[Steve Henson]

*) Removed effectively defunct crypto/store from the build.
[Ben Laurie]

*) Revamp of STACK to provide stronger type-checking. Still to come:
TXT_DB, bsearch(?), OBJ_bsearch, qsort, CRYPTO_EX_DATA, ASN1_VALUE,
ASN1_STRING, CONF_VALUE.
[Ben Laurie]

*) Add a new SSL_MODE_RELEASE_BUFFERS mode flag to release unused buffer
RAM on SSL connections. This option can save about 34k per idle SSL.
[Nick Mathewson]

*) Revamp of LHASH to provide stronger type-checking. Still to come:
STACK, TXT_DB, bsearch, qsort.
[Ben Laurie]

*) Initial support for Cryptographic Message Syntax (aka CMS) based
on RFC3850, RFC3851 and RFC3852. New cms directory and cms utility,
support for data, signedData, compressedData, digestedData and
encryptedData, envelopedData types included. Scripts to check against
RFC4134 examples draft and interop and consistency checks of many
content types and variants.
[Steve Henson]

*) Add options to enc utility to support use of zlib compression BIO.
[Steve Henson]

*) Extend mk1mf to support importing of options and assembly language
files from Configure script, currently only included in VC-WIN32.
The assembly language rules can now optionally generate the source
files from the associated perl scripts.
[Steve Henson]

*) Implement remaining functionality needed to support GOST ciphersuites.
Interop testing has been performed using CryptoPro implementations.
[Victor B. Wagner <vitus@xxxxx>]

*) s390x assembler pack.
[Andy Polyakov]

*) ARMv4 assembler pack. ARMv4 refers to v4 and later ISA, not CPU
"family."
[Andy Polyakov]

*) Implement Opaque PRF Input TLS extension as specified in
draft-rescorla-tls-opaque-prf-input-00.txt. Since this is not an
official specification yet and no extension type assignment by
IANA exists, this extension (for now) will have to be explicitly
enabled when building OpenSSL by providing the extension number
to use. For example, specify an option

-DTLSEXT_TYPE_opaque_prf_input=0x9527

to the "config" or "Configure" script to enable the extension,
assuming extension number 0x9527 (which is a completely arbitrary
and unofficial assignment based on the MD5 hash of the Internet
Draft). Note that by doing so, you potentially lose
interoperability with other TLS implementations since these might
be using the same extension number for other purposes.

SSL_set_tlsext_opaque_prf_input(ssl, src, len) is used to set the
opaque PRF input value to use in the handshake. This will create
an interal copy of the length-'len' string at 'src', and will
return non-zero for success.

To get more control and flexibility, provide a callback function
by using

SSL_CTX_set_tlsext_opaque_prf_input_callback(ctx, cb)
SSL_CTX_set_tlsext_opaque_prf_input_callback_arg(ctx, arg)

where

int (*cb)(SSL *, void *peerinput, size_t len, void *arg);
void *arg;

Callback function 'cb' will be called in handshakes, and is
expected to use SSL_set_tlsext_opaque_prf_input() as appropriate.
Argument 'arg' is for application purposes (the value as given to
SSL_CTX_set_tlsext_opaque_prf_input_callback_arg() will directly
be provided to the callback function). The callback function
has to return non-zero to report success: usually 1 to use opaque
PRF input just if possible, or 2 to enforce use of the opaque PRF
input. In the latter case, the library will abort the handshake
if opaque PRF input is not successfully negotiated.

Arguments 'peerinput' and 'len' given to the callback function
will always be NULL and 0 in the case of a client. A server will
see the client's opaque PRF input through these variables if
available (NULL and 0 otherwise). Note that if the server
provides an opaque PRF input, the length must be the same as the
length of the client's opaque PRF input.

Note that the callback function will only be called when creating
a new session (session resumption can resume whatever was
previously negotiated), and will not be called in SSL 2.0
handshakes; thus, SSL_CTX_set_options(ctx, SSL_OP_NO_SSLv2) or
SSL_set_options(ssl, SSL_OP_NO_SSLv2) is especially recommended
for applications that need to enforce opaque PRF input.

[Bodo Moeller]

*) Update ssl code to support digests other than SHA1+MD5 for handshake
MAC.

[Victor B. Wagner <vitus@xxxxx>]

*) Add RFC4507 support to OpenSSL. This includes the corrections in
RFC4507bis. The encrypted ticket format is an encrypted encoded
SSL_SESSION structure, that way new session features are automatically
supported.

If a client application caches session in an SSL_SESSION structure
support is transparent because tickets are now stored in the encoded
SSL_SESSION.

The SSL_CTX structure automatically generates keys for ticket
protection in servers so again support should be possible
with no application modification.

If a client or server wishes to disable RFC4507 support then the option
SSL_OP_NO_TICKET can be set.

Add a TLS extension debugging callback to allow the contents of any client
or server extensions to be examined.

This work was sponsored by Google.
[Steve Henson]

*) Final changes to avoid use of pointer pointer casts in OpenSSL.
OpenSSL should now compile cleanly on gcc 4.2
[Peter Hartley <pdh@xxxxx>, Steve Henson]

*) Update SSL library to use new EVP_PKEY MAC API. Include generic MAC
support including streaming MAC support: this is required for GOST
ciphersuite support.
[Victor B. Wagner <vitus@xxxxx>, Steve Henson]

*) Add option -stream to use PKCS#7 streaming in smime utility. New
function i2d_PKCS7_bio_stream() and PEM_write_PKCS7_bio_stream()
to output in BER and PEM format.
[Steve Henson]

*) Experimental support for use of HMAC via EVP_PKEY interface. This
allows HMAC to be handled via the EVP_DigestSign*() interface. The
EVP_PKEY "key" in this case is the HMAC key, potentially allowing
ENGINE support for HMAC keys which are unextractable. New -mac and
-macopt options to dgst utility.
[Steve Henson]

*) New option -sigopt to dgst utility. Update dgst to use
EVP_Digest{Sign,Verify}*. These two changes make it possible to use
alternative signing paramaters such as X9.31 or PSS in the dgst
utility.
[Steve Henson]

*) Change ssl_cipher_apply_rule(), the internal function that does
the work each time a ciphersuite string requests enabling
("foo+bar"), moving ("+foo+bar"), disabling ("-foo+bar", or
removing ("!foo+bar") a class of ciphersuites: Now it maintains
the order of disabled ciphersuites such that those ciphersuites
that most recently went from enabled to disabled not only stay
in order with respect to each other, but also have higher priority
than other disabled ciphersuites the next time ciphersuites are
enabled again.

This means that you can now say, e.g., "PSK:-PSK:HIGH" to enable
the same ciphersuites as with "HIGH" alone, but in a specific
order where the PSK ciphersuites come first (since they are the
most recently disabled ciphersuites when "HIGH" is parsed).

Also, change ssl_create_cipher_list() (using this new
funcionality) such that between otherwise identical
cihpersuites, ephemeral ECDH is preferred over ephemeral DH in
the default order.
[Bodo Moeller]

*) Change ssl_create_cipher_list() so that it automatically
arranges the ciphersuites in reasonable order before starting
to process the rule string. Thus, the definition for "DEFAULT"
(SSL_DEFAULT_CIPHER_LIST) now is just "ALL:!aNULL:!eNULL", but
remains equivalent to "AES:ALL:!aNULL:!eNULL:+aECDH:+kRSA:+RC4:@STRENGTH".
This makes it much easier to arrive at a reasonable default order
in applications for which anonymous ciphers are OK (meaning
that you can't actually use DEFAULT).
[Bodo Moeller; suggested by Victor Duchovni]

*) Split the SSL/TLS algorithm mask (as used for ciphersuite string
processing) into multiple integers instead of setting
"SSL_MKEY_MASK" bits, "SSL_AUTH_MASK" bits, "SSL_ENC_MASK",
"SSL_MAC_MASK", and "SSL_SSL_MASK" bits all in a single integer.
(These masks as well as the individual bit definitions are hidden
away into the non-exported interface ssl/ssl_locl.h, so this
change to the definition of the SSL_CIPHER structure shouldn't
affect applications.) This give us more bits for each of these
categories, so there is no longer a need to coagulate AES128 and
AES256 into a single algorithm bit, and to coagulate Camellia128
and Camellia256 into a single algorithm bit, which has led to all
kinds of kludges.

Thus, among other things, the kludge introduced in 0.9.7m and
0.9.8e for masking out AES256 independently of AES128 or masking
out Camellia256 independently of AES256 is not needed here in 0.9.9.

With the change, we also introduce new ciphersuite aliases that
so far were missing: "AES128", "AES256", "CAMELLIA128", and
"CAMELLIA256".
[Bodo Moeller]

*) Add support for dsa-with-SHA224 and dsa-with-SHA256.
Use the leftmost N bytes of the signature input if the input is
larger than the prime q (with N being the size in bytes of q).
[Nils Larsch]

*) Very *very* experimental PKCS#7 streaming encoder support. Nothing uses
it yet and it is largely untested.
[Steve Henson]

*) Add support for the ecdsa-with-SHA224/256/384/512 signature types.
[Nils Larsch]

*) Initial incomplete changes to avoid need for function casts in OpenSSL
some compilers (gcc 4.2 and later) reject their use. Safestack is
reimplemented. 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.
[Steve Henson]

*) 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.
[Steve Henson]

*) 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]

*) 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")

[Bodo Moeller]

*) 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@xxxxx>]

*) New make target "install_html_docs" installs HTML renditions of the
manual pages.
[Oliver Tappe <zooey@xxxxx>]

*) 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.
[Steve Henson]

*) Initial definitions for EVP_PKEY_METHOD. This will be a high level public
key API, doesn't do much yet.
[Steve Henson]

*) 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
EVP_CIPHER structures to avoid later problems in EVP_cleanup().
[Steve Henson]

*) New utilities pkey and pkeyparam. These are similar to algorithm specific
utilities such as rsa, dsa, dsaparam etc except they process any key
type.
[Steve Henson]

*) Transfer public key printing routines to EVP_PKEY_ASN1_METHOD. New
functions EVP_PKEY_print_public(), EVP_PKEY_print_private(),
EVP_PKEY_print_param() to print public key data from an EVP_PKEY
structure.
[Steve Henson]

*) Initial support for pluggable public key ASN1.
De-spaghettify the public key ASN1 handling. Move public and private
key ASN1 handling to a new EVP_PKEY_ASN1_METHOD structure. Relocate
algorithm specific handling to a single module within the relevant
algorithm directory. Add functions to allow (near) opaque processing
of public and private key structures.
[Steve Henson]

*) Implement the Supported Point Formats Extension for
ECC ciphersuites from draft-ietf-tls-ecc-12.txt.
[Douglas Stebila]

*) Add initial support for RFC 4279 PSK TLS ciphersuites. Add members
for the psk identity [hint] and the psk callback functions to the
SSL_SESSION, SSL and SSL_CTX structure.

New ciphersuites:
PSK-RC4-SHA, PSK-3DES-EDE-CBC-SHA, PSK-AES128-CBC-SHA,
PSK-AES256-CBC-SHA

New functions:
SSL_CTX_use_psk_identity_hint
SSL_get_psk_identity_hint
SSL_get_psk_identity
SSL_use_psk_identity_hint

[Mika Kousa and Pasi Eronen of Nokia Corporation]

*) Add RFC 3161 compliant time stamp request creation, response generation
and response verification functionality.
