I've written an AES (Advanced Encryption Standard) library for Arduino. It supports 128, 192 and 256 bit key sizes. Code space overhead is about 4KB I think, each instance requires 240 bytes RAM for subkeys. Fairly tightly coded and checked against official test vectors for ECB mode. Also CBC mode s…

Glad you like it. Next project is elliptic curve public key cryptography! (Only half joking)
