This particular algorithm is a brute force attack on the popular DES Encryption standard. The DES algorithm consists of 4 main classes which will be briefly discussed -The first class takes into consideration the assumption that the in the inputs a

DES加密解密程序 Requirement: Simple interface with inputs (M, K)/(C, K) and output (C)/(M) is required in the program. All data are presented in the hexadecimal format.-DES encryption and decryption procedures
