Description
This class implements the HMAC message authentication code algorithm, as specified in RFC 2104. The underlying DigestEngine (MD5Engine, SHA1Engine, etc.) must be given as template argument. Since the HMACEngine is a DigestEngine, it can be used with the DigestStream class to create a HMAC for a stream.
