Experimental support for encrypt then mac from
draft-gutmann-tls-encrypt-then-mac-02.txt

To enable it set the appropriate extension number (0x10 for the test server)
using e.g. -DTLSEXT_TYPE_encrypt_then_mac=0x10

For non-compliant peers (i.e. just about everything) this should have no
effect.

Add callbacks supporting generation and retrieval of supplemental data entries, facilitating RFC 5878 (TLS auth extensions)
Removed prior audit proof logic - audit proof support was implemented using the generic TLS extension API
Tests exercising the new supplemental data registration and callback api can be found in ssltest.c.
Implemented changes to s_server and s_client to exercise supplemental data callbacks via the -auth argument, as well as additional flags to exercise supplemental data being sent only during renegotiation.

Add support for key wrap algorithms via EVP interface.

Generalise AES wrap algorithm and add to modes, making existing
AES wrap algorithm a special case.

Move test code to evptests.txt

Extend OAEP support. Generalise the OAEP padding functions to support
arbitrary digests. Extend EVP_PKEY RSA method to handle the new OAEP
padding functions and add ctrls to set the additional parameters.

Add new methods DTLS_*_method() which support both DTLS 1.0 and DTLS 1.2 and
pick the highest version the peer supports during negotiation.

As with SSL/TLS options can change this behaviour specifically
SSL_OP_NO_DTLSv1 and SSL_OP_NO_DTLSv1_2.

Just a sample, real world applications would have to be cleverer.

Add new verify options to set checks.

Remove previous -check* commands from s_client and s_server.

Fixes to X509 hostname and email address checking. Wildcard matching support.
New test program and manual page.

to print results of checks.

the connection parameters.

New option -verify_quiet to shut up the verify callback unless there is
an error.

client hello message. Previously this could only be retrieved on an initial
connection and it was impossible to determine the cipher IDs of any uknown
ciphersuites.

change the current certificate (in s->cert->key) to the one used and then
SSL_get_certificate and SSL_get_privatekey will automatically work.

right response is stapled. Also change SSL_get_certificate() so it
returns the certificate actually sent.  See

certificates: checks for matching certificate type and issuer name
comparison.

Print out results of checks for each candidate chain tested in
s_server/s_client.

possible to have different stores per SSL structure or one store in
the parent SSL_CTX. Include distint stores for certificate chain
verification and chain building. New ctrl SSL_CTRL_BUILD_CERT_CHAIN
to build and store a certificate chain in CERT structure: returing
an error if the chain cannot be built: this will allow applications
to test if a chain is correctly configured.

Note: if the CERT based stores are not set then the parent SSL_CTX
store is used to retain compatibility with existing behaviour.

configuration).

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.
