Web3 we explain the differential cryptanalysis and the idea of extracting key bits of a SPN by looking at the differences between input and output pairs. In section 4 we explain how the linear cryptanalysis can be applied to the Data Encryption Standard (DES). First by a small 3 rounds DES and then the full 16 rounds DES.
