For anyone saying "uSinG aEs-Ni iS cHeAtInG": a) AESKEYGENASSIST only supports round constants as immediate arguments, so every other implementation I saw unrolls the key expansion loop. b) I tricked a lot of smart CTF players into thinking this was a non-standard AES impl :P

c) Explain the round loop exit condition. d) Make the code smaller :P (I think this is possible, the shuffling stage was kinda optimised for obscurity rather than size)

I'm guessing it isn't bitsliced and therefore isn't constant time?

It uses AES-NI, which should be constant time, I think? That said, I wouldn't use this code for anything important...

wow i just realized you need to do the self-modification to make it it, when i first looked at the challenge thought it was just to make it harder for the reader
