|
<p>SSL_get_verify_result() returns the result of the verification of the X509 certificate presented by the peer, if any.</p>
|
||
|
|
|
||
|
|
<h1 id="NOTES">NOTES</h1>
|
||
|
|
|
||
|
|
<p>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().</p>
|
||
|
|
|
||
|
|
<p>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 <a href="../man3/SSL_CTX_set_verify.html">SSL_CTX_set_verify(3)</a> or <a href="../man3/SSL_set_verify.html">SSL_set_verify(3)</a> and retrieve the errors from the error stack there, because once <a href="../man3/SSL_connect.html">SSL_connect(3)</a> returns, these errors may no longer be available.</p>
|
||
|
|
|
||
|
|
<p>The verification result is part of the established session and is restored when a session is reused.</p>

<p>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 <a href="../man3/SSL_get_peer_certificate.html">SSL_get_peer_certificate(3)</a>.</p>
