"DESCRIPTION"
Header "DESCRIPTION" \fBSSL_get_peer_signature_nid() sets *psig_nid to the \s-1NID\s0 of the digest used
by the peer to sign \s-1TLS\s0 messages. It is implemented as a macro.
\fBSSL_get_peer_signature_type_nid() sets *psigtype_nid to the signature type used by the peer to sign \s-1TLS\s0 messages. Currently the signature type is the \s-1NID\s0 of the public key type used for signing except for \s-1PSS\s0 signing where it is \s-1EVP_PKEY_RSA_PSS\s0. To differentiate between \fBrsa_pss_rsae_* and rsa_pss_pss_* signatures, it's necessary to check the type of public key in the peer's certificate.
\fBSSL_get_signature_nid() and SSL_get_signature_type_nid() return the equivalent information for the local end of the connection.
"RETURN VALUES"
Header "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 \s-1RSA\s0 key exchange or is anonymous), the \s-1TLS\s0 version is below 1.2 or
the functions were called too early, e.g. before the peer signed a message.
