type DESMode

type DESMode uint

DESMode ECB(electronic code book)是最简单的方式，它将明文分组加密后的结果直接成为密文分组。 优缺点：模式操作简单；明文中的重复内容将在密文中表现出来，特别对于图像数据和明文变化较少的数据；适于短报文的加密传递。

CBC(cipher block chaining)的原理是加密算法的输入是当前的明文分组和前一密文分组的异或，第一个明文分组和一个初始向量进行异或，这样同一个明文分组重复出现时会产生不同的密文分组。 特点：同一个明文分组重复出现时产生不同的密文分组；加密函数的输入是当前的明文分组和前一个密文分组的异或；每个明文分组的加密函数的输入与明文分组之间不再有固定的关系；适合加密长消息。
