I need a somewhat simple encrypting method of storing data that can be decrypted. This was the only thing I could get to work. When I try EzCrypto I run into an error "uninitialized constant" or something. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
