WebLinear cryptanalysis is a powerful method of cryptanalysis of block ciphers introduced by Matsui in 1993 [ 1 ]. The attack in its current form was first applied to the Data Encryption Standard (DES), but an early variant of linear cryptanalysis, developed by Matsui and Yamagishi, was already successfully used to attack FEAL in 1992 [ 12 ].

WebOn this page we will focus on automatic cryptanalysis of substitution ciphers, i.e. writing programs to solve these ciphers for us.
