DES (Data Encryption Standard) is a group symmetric cipher algorithm . des employs a 64-bit packet length and a 56-bit key length , which takes 64-bit inputs through a series of transformations to get 64-bit output. Decryption uses the same steps

First, IntroductionDES is a common type of symmetric encryption, all called Data Encryption Standard, which is the encryption standards, is a key encryption using the block algorithm. The key length is 64 bits (bit), and the key that exceeds the
