SSL_GET_VERIFY_RESULT(3) Library Functions Manual SSL_GET_VERIFY_RESULT(3)
NAME
SSL_get_verify_result — get result of peer certificate verification
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.
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.
RETURN VALUES
The following return values can currently occur:
X509_V_OK
The verification succeeded or no peer certificate was presented.
Any other value
Documented in openssl(1).

HISTORY
SSL_get_verify_result() first appeared in SSLeay 0.6.1 and has been available since OpenBSD 2.4.
BUGS
If no peer certificate was presented, the returned result code is X509_V_OK. This is because no verification error occurred; however, it does not indicate success. SSL_get_verify_result() is only useful in connection with SSL_get_peer_certificate(3). GNU June 26, 2021 SSL_GET_VERIFY_RESULT(3)
