B<rsa_pss_rsae_*> and B<rsa_pss_pss_*> signatures, it's necessary to check
the type of public key in the peer's certificate.

=head1 RETURN VALUES
These functions return 1 for success and 0 for failure. There are several
possible reasons for failure: the cipher suite has no signature (e.g. it
uses RSA key exchange or is anonymous), the TLS version is below 1.2 or
-the functions were called before the peer signed a message.
