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().
Sometimes there can be a sequence of errors leading to the verification
failure as reported by SSL_get_verify_result().
To get the errors, it is necessary to setup a verify callback via
SSL_CTX_set_verify(3) or SSL_set_verify(3) and retrieve the errors
from the error stack there, because once SSL_connect(3) returns,
these errors may no longer be available.
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 openssl-verify(1).
