an SSL signature (MD5 and SHA1 message digests with PKCS #1 padding
and no algorithm identifier) is created.
-The random number generator must be seeded prior to calling RSA_sign().
-
RSA_verify() verifies that the signature B<sigbuf> of size B<siglen>
matches a given message digest B<m> of size B<m_len>. B<type> denotes
the message digest algorithm that was used to generate the signature.
