Overview

Code in this file solves challenge 17 of set 3 of the Cryptopals.

Code in this file solves challenge 12 and 14 of set 2 of the Cryptopals.

Code in this file is an alternative implementation of the byte-at-a-time attack that I found in the wild. It's a smarter solution, and is about 18% faster than the other one (less memory usage, too). This is a port of the original solution in Python.
