SSL_set_verify_result - override result of peer certificate verification
 #include <openssl/ssl.h>
 void SSL_set_verify_result(SSL *ssl, long verify_result);
SSL_set_verify_result() sets verify_result of the object
  ssl to be the result of the verification of the X509 certificate
  presented by the peer, if any.
SSL_set_verify_result() overrides the verification result. It only
  changes the verification result of the ssl object. It does not become
  part of the established session, so if the session is to be reused later, the
  original value will reappear.
The valid codes for verify_result are documented in
    verify(1).
SSL_set_verify_result() does not provide a return value.
