Des algorithm in detail
WebMar 14, 2024 · Data Encryption Standard (DES) is a block cipher algorithm that creates plain text in blocks of 64 bits and transform them to ciphertext using keys of 48 bits. It is a symmetric key algorithm, which defines that the similar key is used for encrypting and decrypting information. WebJan 3, 2024 · DES is a complex algorithm that works by dividing an input text into smaller 64-bit blocks. Each block then goes through an initial permutation, and the result of the initial permutation is further divided into two parts called LPT and RPT. These two parts then go through the Feistel function for 16 rounds.
