 RSA_sign() signs the message digest B<m> of size B<m_len> using the
-private key B<rsa> as specified in PKCS #1 v2.0. It stores the
-signature in B<sigret> and the signature size in B<siglen>. B<sigret>

+B<sigret> must point to RSA_size(B<rsa>) bytes of memory.
 Note that PKCS #1 adds meta-data, placing limits on the size of the
 key that can be used.
