SSL_get_verify_result - get result of peer certificate verification
Synopsis #include <openssl/ssl.h> long
SSL_get_verify_result(SSL *ssl);
DESCRIPTIONSSL_get_verify_result() returns the result of the verification
of the X509 certificate presented by the peer, if any. NOTESSSL_get_verify_result() can only return one error code while
the verification of a certificate can fail because of many reasons
at the same time. Only the last verification error that occurred
during the processing is available from SSL_get_verify_result().
The verification result is part of the established session
and is restored when a session is reused.
RestrictionsIf no peer certificate was presented, the returned result
code is X509_V_OK. This is because no verification error occurred,
it does however not indicate success. SSL_get_verify_result() is
only useful in connection with SSL_get_peer_certificate(3) . RETURN VALUESThe following return values can currently occur:
X509_V_OK The verification succeeded or no peer certificate was presented.
Any other value Documented in verify(1) .
