SSL_get_verify_result3ssl
Get result of peer certificate verification
Usage
#include <openssl/ssl.h>long SSL_get_verify_result(const SSL *ssl);
Overview
SSL_get_verify_result() returns the result of the verification of the X509 certificate presented by the peer, if any. ssl MUST NOT be NULL.
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.
Return values
The following return values can currently occur:
X509_V_OK
|
The verification succeeded or no peer certificate was presented. |
|---|---|
Any other value
