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).

SEE ALSO¶

openssl(1), ssl(3), SSL_CTX_set_verify(3), SSL_get0_peername(3), SSL_get_peer_certificate(3), SSL_set_verify_result(3)

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).
