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.
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
- Documented in verify(1).
