Algorithm for Data Encryption Standard

Requires a Wolfram Notebook System
Interact on desktop, mobile and cloud with the free Wolfram Player or other Wolfram Language products.
This Demonstration shows an example of the DES (Data Encryption Standard) algorithm, which is the most widely used encryption algorithm in the world. DES encrypts groups of 64 message bits and requires a key of 64 message bits. If a message or key is less than 64 message bits, it is padded with zeros to the right. All of the example messages are padded to the right with zeros to make a message with groups of 64 message bits.
