简单的加密算法,可逆与不可逆 数据加密: 算法1:(不可逆) 将ASCII表中32~~126中的字符，加密后，显示为128~~255的字符. 128~~255的字符会让人看起来头痛些。。。。。。安全. 当ch[?]的值为偶数时：ch[?]=255-ch[?]的个位*10-ch[?]的十位 当ch[?]的值为奇数时: ch[?]=128+ch[?]的个位*10+ch[?]的十位 当ch[?]的值为质数时：ch[?]=128+ch[?]的个位

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 s

此算法用于实现一种基于查找表的混沌加密，将随机产生的一个数组加密后输出，同时也可以将解密后的数据与原始数据进行对照，本算法已经在5509芯片上进行实时运行过，用于对16bit语音信号的高16位加密，能满足实时性。-The algorithm used to achieve a look-up table based chaotic encryption, will be an array of randomly generated encrypted output, but also can d

A rainbow table is a precomputed table for reversing cryptographic hash functions, usually for cracking password hashes. Tables are usually used in recovering the plaintext password, up to a certain length consisting of a limited set of characters. I
