New Year's Greetings — Part 2 Level 1

by Marc Gutgesell, published on 3/21/2016

This series consists of five parts which are based on each other and that will be getting more and more complicated with each part. Part 4 contains a little New Year's greeting of the author and part 5 teaches us something about the weaknesses of this method. Part 2 modifies the encryption of part 1 a little bit.
