+=head1 NAME
+SSL_get_peer_signature_nid, SSL_get_peer_signature_type_nid - get TLS
+message signing types
+=head1 SYNOPSIS
+ #include <openssl/ssl.h>
+ int SSL_get_peer_signature_nid(SSL *ssl, int *psig_nid);
+ int SSL_get_peer_signature_type_nid(const SSL *ssl, int *psigtype_nid);
+SSL_get_peer_signature_nid() sets B<*psig_nid> to the NID of the digest used
+by the peer to sign TLS messages. 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.
+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.
