The acts_as_authentic method allows you to pass a :crypto_provider option. This allows you to use any type of encryption you like. Just create a class with a class level encrypt and matches? method. See example below.
class MyAwesomeEncryptionMethod def self.encrypt(*tokens) # the tokens passed wil be an array of objects, what type of object is irrelevant # just do what you need to do with them and return a single encrypted string. # for example, you will most likely join all of the objects into a single string and then encrypt that string end def self.matches?(crypted, *tokens) # return true if the crypted string matches the tokens. # depending on your algorithm you might decrypt the string then compare it to the token, or you might # encrypt the tokens and make sure it matches the crypted string, its up to you end end
