[Crack Hack] desende DL : 0: 自己编的DES加密、解密算法，可实现windows下任何文件的加密、解密，尤其适用使用公用电脑而一些私人的文件不想被别人看到的情况，可设置八个字节的密钥，也就是每一位可以从0到255，这样对方就算已知置换矩阵和S盒的情况下用穷举法破解的难度也在2的32次幂，还是相当安全的。加密：DESencrypt.exe 解密：DESdecrypt.exe-own addendum to the DES encryption, decryption algorithms can be realized under any windows document encryption, decryption, In particular, the use of common computer application and some private documents do not want others to see, can be set up eight bytes of keys, Each one is from 0 to 255. known each other even if such replacement matrix and the S-box using exhaustive method is difficult to decipher the two 32 power, still quite safe.

[Crack Hack] DES DL : 0: 算法流程 1.将要处理的二进制串进行IP置换 2.将密钥进行PC1置换(64位转为56位), 3.进行16轮操作,对于第i轮操作: 1)将上一次得到的PC1密钥(级除去第一次外,其他的都经过移位处理)的结果左右部分(各28位)分别循环左移1位或2位,然后将移位后的密钥进行PC2[i]置换. 2)将处理串均等分为左右两串Li,Ri(各32位),然后将右串Ri通过E盒拓展为新的右串R (48位),R 与上一步得到的PC2[i]子密钥进行异或操作,结果通过S盒输出(48为转为32位),然后通过P盒直接置换,再与Li异或. 3)将Ri赋给作出Li,R 赋值给Ri. 4)合并处理串StrText=Li+Ri. 4.将最新的处理串进行IP_1置换,置换结果即为所求的加密串或解密串加密解密的区别在每轮操作中,加密使用的PC2密钥顺序为0~15,解密使用的PC2密钥顺序为15~0. -Algorithm flow A binary string to be processed is substituted for IP 2 key the PC1 replacement (64 into 56) 16 operation, the operation for the i-th round: 1) about the results of the last PC1 key (remove the first time, the others have been shifting processing) (28) rotate left one or two, and then will shift key PC2 [i] replacement. 2) is divided into the equal treatment string around two bunches of Li, Ri (32), and then expand the right string Ri E box (48-bit), the right string R R and the previous step PC2 i] subkey XOR operation result is output via the S-box (48 to 32 conversion), and then directly through the P box replacement and XOR with Li. 3) the Ri to make Li, R is assigned to Ri. 4) merger deal with string StrText Ri = Li+. 4. Latest processing string IP_1 replacement, replacement results shall request string encryption or decryption string Encryption and decryption of difference In each round of operations, PC2 key e
