NAME
SSL_get_verify_result - get result of peer certificate verification
LIBRARY
libcrypto, -lcrypto
SYNOPSIS
#include <openssl/ssl.h>
long SSL_get_verify_result(const SSL *ssl);
DESCRIPTION
SSL_get_verify_result() returns the result of the verification of the X509 certificate presented by the peer, if any.
NOTES
SSL_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.
BUGS
If 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 VALUES
The following return values can currently occur:
-
X509_V_OK
-
The verification succeeded or no peer certificate was presented.
-
Any other value
-
