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.

Originally written by Daiki Ueno. Converted to a RubyGem by Geoffrey Grosenbach

USAGE:

    require 'hmac'
    require 'hmac_sha1.rb'

    key = get_key_for_signing
    sha1 = HMAC::SHA1.new(key)
    sha1 << get_some_text_to_digest
    sha1 << get_some_more_text_to_digest
    puts sha1.hextdigest()

    # Or, if you like base64 encodings
    require 'base64'
    puts Base64.encode64(sha1.digest())
