Created October 15, 2010 10:00
# Merb SessionCookie unmarshalling with validation against secret key. Useful for 3rd service
# (like socket server) to map cookie -> user_id. Pretty much all of this jacked from Merb
# source and distilled into the same place.
require 'base64' # to convert Marshal.dump to ASCII
require 'openssl' # to generate the HMAC message digest
# Cookies can typically store 4096 bytes.
