+SSL_CTX_check_private_key() checks the consistency of a private key with

+key/certificate pair (RSA/DSA) is installed, the last item installed will
+be checked. If e.g. the last item was a RSA certificate or key, the RSA

+the same check for B<ssl>. If no key/certificate was explicitly added for
+this B<ssl>, the last item added into B<ctx> will be checked.

 The internal certificate store of OpenSSL can hold two private key/certificate
