The Data Encryption Standard (DES) is a symmetric-key algorithm for the encryption of digital data. Symmetric-key algorithms use the same key for both encryption and decryption, which necessitates secure key management. DES is a block cipher, meaning it encrypts data in fixed-size blocks. Specifically, DES processes data in 64-bit blocks, utilizing a 56-bit key to
