It is implemented as a macro. + +SSL_get_peer_signature_type_nid() sets B<*psigtype_nid> to the signature +type used by the peer to sign TLS messages. Currently the signature type +is the NID of the public key type used for signing except for PSS signing +where it is B<EVP_PKEY_RSA_PSS>. To differentiate between +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. + +=head1 SEE ALSO + +L<ssl(7)>, L<SSL_get_peer_certificate(3)>, + +=head1 COPYRIGHT + +Copyright 2017-2018 The OpenSSL Project Authors.
