public_key: Public RSA key is present in private key
Change the return value from {#'RSAPublicKey'{}, #'RSAPrivateKey'{}} to #'RSAPrivateKey'{} This conforms to the #'ECPrivateKey'{} return value. Note that DH key will be returned as {Public::integer(), Private::integer()} as there is no key structure (record) only two integers. Maybe we would like to add extraction functions for the public key from the private ones later.
