details in s_client.

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.

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.

appropriate checks in tls1_check_chain.

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.

Support - as a file for standard input or output.

Add -badsig option to generate invalid signatures for testing.

New -rmd option to specify digest to sign OCSP responses with.

Add new verify options to set checks.

Don't verify our own responses.

modification to the OCSP helper purpose breaks normal OCSP verification. It is
no longer needed now we can trust partial chains.
