Des is a 16-wheeled Feistel structure cipher with a packet length of 64 bits, a 56-bit key to encrypt a 64-bit plaintext string, and a 64-bit cipher string. Where the key is 64 bits, the utility is 56 bits, and the other 8 bits are used as parity. The process of encryption is the first 64-bit plaintext group initial replacement, then the left and right two parts after 16 rounds of iterations, and then the cycle shift and transformation, and finally th
