About this document
Overview of Data Encryption Standard (DES) by divs4002 is a document available to read on EtoBox.
The Data Encryption Standard (DES) is a symmetric-key block cipher developed by NIST, first published in 1975. It consists of an encryption process involving initial and final permutations, sixteen Feistel rounds, and a DES function that applies a 48-bit key to produce a 32-bit output. Key generation for DES involves creating sixteen 48-bit keys from a 56-bit cipher key.
