用Matlab实现的DES算法。在Matlab窗口输入DESDECP(a,b,n),其中a，b表示16进制的明文和密钥，n为1表示加密，否则表示加密。-DES algorithm using Matlab. In Matlab window field DESDECP (a, b, n), where a, b indicates a hexadecimal plaintext and key, n is 1 shows an encryption, or that encryption.

DES分组加密程序的Matlab版本，内容多了一些小修改和注释，实测可以使用，未改进不够16字数的自动补零问题-DES block encryption program Matlab version, as some more minor changes and comments, you can use the actual, not enough to improve the auto-fill 16 words zero problems
