SSL_get_verify_result(3)

NAME
SSL_get_verify_result - get result of peer certificate verification

LIBRARY
libcrypto, -lcrypto

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().

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).
