Hello everyone! Here's a complete implementation of AES in GNU APL, that I thought might be worth sharing:
https://gist.github.com/rhaberkorn/78a982dbd49bc896175607289507cb64 It's purely educational and written to be as close to the FIPS 197 standard as possible. In fact, this was a course work for a cryptography class and left the instructor quite puzzled. ;-) Still encryption and decryption for all standard key sizes is supported. Getting rid of unused and trivial functions and the examples at the end, this is a mere 47 lines. Best regards, Robin
