# Generating S-Boxes For Block Ciphers
## Abstract
In this paper, we will explore methods for generating cryptographically strong s-boxes, using almost perfect nonlinear functions. We will also look at methods for determining the quality of any given s-box. In addition to looking at the theory, we implement the algorithms we find, using the python 3 programming language.
