-# = digest/hmac.rb
-#
-# An implementation of HMAC keyed-hashing algorithm
-#
-# == Overview
-#
-# This library adds a method named hmac() to Digest classes, which
-# creates a Digest class for calculating HMAC digests.
-#
-# == Examples
-#
-# require 'digest/hmac'
-#
-# # one-liner example
-# puts Digest::HMAC.hexdigest("data", "hash key", Digest::SHA1)
-#
-# # rather longer one
-# hmac = Digest::HMAC.new("foo", Digest::RMD160)
-#
-# buf = ""
-# while stream.read(16384, buf)
-# hmac.update(buf)
-# end
-#
-# puts hmac.bubblebabble
