data is not a multiple of 8 bytes. For decryption, will remove the trailing characters that match this pad character from the last 8 bytes of the unencrypted data block. padmode -> Optional argument, set the padding mode, must be one of PAD_NORMAL ...
The method with symmetric encryption is used of the encryption of DES, which uses the same dense key for encryption and decryption. In this paper, introduced the design of encryption、 work of principle of DES and the the algorithm of DES in detail.The algorithm of DES has three entrance ...
5.DES algorithm decryption process is the same, the only difference is that the first iteration used Subkey K15, K14 ,..., second last with K0, the algorithm itself without any change. DES算法的解密过程一样的,区别仅仅在于第一次迭代时用子密钥K15,第二次K14、...,最后一次用K0,算法本身...
