Cryptography in Microcontroller

One of my junior at President University, Edi Permadi finally released his works on the net about en/decryption and hashing method for PIC16F84. I personally like cryptography as well as its implementation in hardware (microcontroller or IC design). His works which already published are :

My comment :

It is a very interesting implementation, however NIST has chosen Rijndael to replace DES. I hope in the future he will be able to implement Rijndael in microcontroller or FPGA.

MD5 is no longer secure, it has collision. SHA1 is much better.
