(const
SSL *ssl);
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.
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).
SSL_get_verify_result
() first appeared in
SSLeay 0.6.1 and has been available since OpenBSD
2.4.
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).
