algorithm(+Algorithm): One of sha1 (default), sha224, sha256, sha384 or sha512
encoding(+Encoding): If Data is a sequence of character codes, this must be translated into a sequence of bytes, because that is what the hashing requires. The default encoding is utf8. The other meaningful value is octet, claiming that Data contains raw bytes.
