ruby-hmac: HMAC for RubyThis 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.
NOTE: If your apps can assume Ruby/OpenSSL available, consider using OpenSSL::HMAC instead.
