About this document
DES Algorithm Overview and Process by Mainford Mutandavari is a document available to read on EtoBox.
DES is a symmetric encryption algorithm that uses a 64-bit block size and 56-bit key. It operates on 64-bit plaintext blocks by performing an initial permutation followed by 16 rounds of substitution and permutation using 48-bit subkeys generated from the original key. The final output is subjected to an inverse permutation to produce the 64-bit ciphertext.
