Cryptographic Learning system

Hi peeps,

I'm currently starting my final year for Uni and for my thesis I am going to produce a Computer Aided Learning system that will help students to learn the basics of cryptography and cryptoanalysis (Like Xor and Ceaser shift etc).

Part of the project is to research any previous knowledge on the subject area, so if any of you have heard about a system that helps peeps to learn cryptographic algorithms and approaches I would appreciate it if you repied here or even sent a mail to Here ...

Also I've been searching around for academic resources, I've found the 'Applied Cryptography' bible and I need to find a 'cryptography' forum or webring, again can anyone help me out here?

many thanks for your time, I look forwards to any replies.
