Also add ctrl to set client certificate types. If not used sensible values
will be included based on supported signature algorithms: for example if
we don't include any DSA signing algorithms the DSA certificate type is
omitted.
Fix restriction in old code where certificate types would be truncated
if it exceeded TLS_CT_NUMBER.
the permitted signature algorithms for server and client authentication
are the same but it is now possible to set different algorithms for client
authentication only.

to have similar checks in it.
Add new "cert_flags" field to CERT structure and include a "strict mode".
This enforces some TLS certificate requirements (such as only permitting
certificate signature algorithms contained in the supported algorithms
extension) which some implementations ignore: this option should be used
with caution as it could cause interoperability issues.

inappropriate) parameter set and delve into EC internals we just

Don't allocate a structure to handle ECC extensions when it is used for

Make supported curves configurable.

Before this the only way to add a custom chain was in the parent SSL_CTX
(which is shared by all key types and SSL structures) or rely on auto
chain building (which is performed on each handshake) from the trust store.
The cipher definitions of these ciphersuites have been around since SSLeay
but were always disabled. Now OpenSSL supports DH certificates they can be
finally enabled.
Various additional changes were needed to make them work properly: many
unused fixed DH sections of code were untested.
New function to retrieve compression method from SSL_SESSION structure.
Delete SSL_SESSION_get_id_len and SSL_SESSION_get0_id functions
as they duplicate functionality of SSL_SESSION_get_id. Note: these functions
have never appeared in any release version of OpenSSL.

At present only RSA key exchange ciphersuites work with TLS v1.2 as the
