MD5 算法


增加 padding 使得数据长度(bit为单位)模 512 为 448。
如果数据长度正好是模 512 为 448, 增加 512 个填充 bit,
也就是说填充的个数为 1-512 。第一个 bit 为 1,其余全部为0。


将数据长度转换为 64bit 的数值,如果长度超过 64bit
所能表示的数据长度的范围,值保留最后 64bit,
增加到前面填充的数据后面,使得最后的数据为 512bit 的整数倍。
也就是 32bit 的 16 倍的整数倍。在 RFC1321 中,32bit
称为一个 word。


用到 4 个变量,分别为 A、B、C、D,均为 32bit 长。初始化为:
