SSL_get_verify_result(3)

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 veri-
       fication of a certificate can fail because of many reasons at the same
       time. Only the last verification error that occurred during the pro-
       cessing is available from SSL_get_verify_result().

       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 how-
       ever 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 verify(1).
