87adf1fa96 new function SSL_is_server to which returns 1 is the corresponding SSL context is for a server 2012-07-03 14:25:17 +00:00

18d7158809 Add certificate callback. If set this is called whenever a certificate
is required by client or server. An application can decide which
certificate chain to present based on arbitrary criteria: for example
supported signature algorithms. Add very simple example to s_server.
This fixes many of the problems and restrictions of the existing client
certificate callback: for example you can now clear existing certificates
and specify the whole chain.

d61ff83be9 Add new "valid_flags" field to CERT_PKEY structure which determines what
the certificate can be used for (if anything). Set valid_flags field
in new tls1_check_chain function. Simplify ssl_set_cert_masks which used
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.

a43526302f Add support for automatic ECDH temporary key parameter selection. When
enabled instead of requiring an application to hard code a (possibly
inappropriate) parameter set and delve into EC internals we just
automatically use the preferred curve.

d0595f170c Initial revision of ECC extension handling.
Tidy some code up.

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

Make supported curves configurable.

Add ctrls to retrieve shared curves: not fully integrated with rest of
ECC code yet.

c526ed410c Revise ssl code to use a CERT_PKEY structure when outputting a
certificate chain instead of an X509 structure.

This makes it easier to enhance code in future and the chain
output functions have access to the CERT_PKEY structure being
used.

8e1dc4d7ca Support for fixed DH ciphersuites.
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.

08557cf22c Initial "opaque SSL" framework. If an application defines
OPENSSL_NO_SSL_INTERN all ssl related structures are opaque
and internals cannot be directly accessed. Many applications
will need some modification to support this and most likely some
additional functions added to OpenSSL.

The advantage of this option is that any application supporting
it will still be binary compatible if SSL structures change.

13f6d57b1e Add support for magic cipher suite value (MCSV). Make secure renegotiation
work in SSLv3: initial handshake has no extensions but includes MCSV, if
server indicates RI support then renegotiation handshakes include RI.

NB: current MCSV value is bogus for testing only, will be updated when we
have an official value.

Change mismatch alerts to handshake_failure as required by spec.

Also have some debugging fprintfs so we can clearly see what is going on
if OPENSSL_RI_DEBUG is set.
