About this document
Understanding the DES Algorithm Steps by Shubhra Shah is a document available to read on EtoBox.
The document summarizes how the Data Encryption Standard (DES) algorithm works to encrypt messages. DES operates on 64-bit blocks of plaintext, dividing each block into two 32-bit halves and encrypting the block using a 56-bit encryption key to produce a ciphertext block of the same size. The key is used to generate 16 subkeys through a permutation process. DES then performs multiple rounds of permutations and substitutions on the plaintext halves using the subkeys before recombining the halves to produce t
