Understanding the Mysterious DES Encryption Algorithm

1 Introduction DES algorithm is a common block cipher algorithm proposed by IBM in 1971. The DES algorithm is a typical representative of block ciphers and is also the most widely used symmetric encryption algorithm. This article will detail the principles and implementation process of DES. 1.1 Plaintext Plaintext refers to data that has not … Read more
