Data Encryption Standard (DES) is the most widely used block cipher in the world. It encrypts 64-bit data using a 64-bit key.
Given a plaintext and a key, this application will compute the DES ciphertext, and log every step in the process. Simply type a hexadecimal value into one of the input boxes, and the output will update automatically.
