Including the major types of encryption function, the one-way function summary, the pseudo-random number generator, public key encryption function. You can download the source of the document and its Note : http :// in C www.libtomcrypt.org libtomcrypt builde r6 compiler for tomcrypt.lib

常见加密算法汇总的C++实现，初学加密算法者适用-Common encryption algorithm aggregate C++ Realize, learning to apply the encryption algorithm

说明：  dsa数字签名 系统功能需求： 1.对文件进行签名，生成一个独立于原文的签名文件； 2.可以对文件进行签名，在文件后追加签名信息； 3.具有密钥管理的功能，比如密钥的生成、导入、导出； 4.可以对word文档实施操作，对word文档的内容进行签名； 5.能够比对已经实施的签名，防止进行重复的签名，以防止重放攻击； 6.可以对已经签名的文件进行单独的源文件和签名信息的分离操作。(DSA digital signature System functional requirements: 1. Sign the document and generate a signature file independent of the original text. 2. The document can be signed and the signature information can be added after the document. 3. It has the function of key management, such as key generation, import and export. 4. Word documents can be operated and the contents of Word documents can be signed. 5. Ability to compare existing signatures and prevent duplicate signatures to prevent replay attacks; 6. It is possible to separate the source file from the signature information of the signed file.)

MISTY 加密算法 二进制兼容的加密算法,加密匙可到128位-MISTY binary compatible encryption algorithm encryption algorithms, encryption keys can be 128

主要介绍算法的实现方式和流水线实现，而且有详细的原理介绍，推理，源码和仿真结果-The main way of introduction Algorithm and pipelining to achieve, but also has a detailed introduction of the principle, reasoning, source code and simulation results

利用汇编语言实现DES加密算法-using assembly language to achieve DES encryption algorithm

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.
