超级兔子有一个文件加密功能，文件被加密以后，打开该文件时，回转到控制面板，可是我们忘了密码怎么办呢？这里提供了一个简单方法-Super rabbit has a file encryption, file is encrypted then, open the file, back to the control panel, but we forget the password how to do? Here provides a simple way

21加密算法,用vB语言编写实现,可了解各种加密算法的结构(21, encryption algorithm, and realize vB languages, can understand the structure of a variety of encryption algorithms)

uthash 是一个C语言的哈希表，支持各种结构类型的存储、添加、删除，这些操作都在固定的时间完成，跟哈希表本身的大小无关。键也可以是任何类型的数据。-is a C language uthash the hash table to support a variety of structural types of storage, add, delete, these operators are in a fixed time to complete, with the hash table size in itself has nothing to do. Keys can also be any type of data.
