Cryptopals Set 2: Block Crypto

Moving on to the second set we move into the territory of breaking modern cryptography. We mainly concern ourselves with ECB and CBC mode and various ways to break systems that use these modes in an unsafe manner.

Cryptopals Set 1: Basics

In this first set we cover some of the fundamental building blocks we will use for many of the coming challenges. We also warm up our cryptanalysis skills by breaking a couple classical cipher systems.
