== DESCRIPTION:
  
This module provides common interface to HMAC functionality. HMAC is a kind of "Message Authentication Code" (MAC) 
algorithm whose standard is documented in RFC2104. Namely, a MAC provides a way to check the integrity of information 
transmitted over or stored in an unreliable medium, based on a secret key.
