算术运算实现字母的替换。凯撒加密就是一种单字母替换法：通过用户给出密钥将字母加上密码变成密文-Arithmetic operations to achieve the replacement of letters. Caesar encryption is the replacement of a single-letter law: the user is given the letter key will be encrypted into a ciphertext

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.
