Which bits of the key are used for parity checking in DES?
Thursday, 08 May 2025 by Theresa Sittel
The Data Encryption Standard (DES) is a symmetric-key block cipher that was once a widely used method for data encryption. It operates on 64-bit blocks and uses a 56-bit key for encryption and decryption processes. One of the lesser-known aspects of DES is the inclusion of parity bits within its key structure, which are used
