这是我上信息安全课做的作业，des的加密算法。

一个用移位思想实现的简单数据加密程序，因为不论是大写还是小写字母,其ASC码值都是按顺序排列的.故可以用相对应的ASC码值进行判断以及算法实现.-a shift ideology with a simple data encryption procedures, because both uppercase or lowercase letters, the value of ASC codes are arranged in chronological order according to the. It can be used to be the relative value of ASC code of judgment and algorithm.
