sm4国密对称算法源码和使用sample，请参考。。(sm4 source code sample)

看到RSA加密的C++类下载的人不少，我也下载了，并且稍微改动了一下，使它看上去更加易懂。在新年随手写了一套RSA文件加密，用win32dll封装使用了这个类，用C#写了文件加密和操作界面，可以实现密钥的保存和对任何文件的RSA加密操作。送给大家祝大家新年快乐。(see RSA encryption C downloaded to many people, I have downloaded and slightly altered a bit it looks more comprehensible. New Year threw in a written document RSA encryption, win32dll Compliant with the use of this category, C# to write document encryption and interface, can achieve key to the preservation of any documents and the RSA encryption operation. Give you wish you a happy New Year.)

采用c++实现RC4加密解密算法，该代码可以加密解密任意格式的文件( U91C7 u758ccc_cn R U6587 u4EF6)

编写的DES 对称加解密技术，可随时进行明文密文之间的转换，有需要的朋友可以下载测试！本人目的打算对后台数据库的敏感信息字段用该方法加密，然后用软件权限控制读取，这样即使直接SQL后台取数，也得不到明文数据。(Write DES symmetrical encryption technology, may at any time for conversion between plaintext cipher, friends in need can be download test! I purpose going to the backstage database of sensitive information field with the method of encryption, and then use software to read access control, so even if the SQL backend access directly, also can not get clear data. )

ElGamal加密算法，经过测试可以编译运行(ElGamal Encryption )

一个中国剩余定理的简单算法,密码学基础算法(Chinese Remainder Theorem a simple algorithm, based on cryptography algorithm)

自己动手写加壳程序，按照文档一步一步来，做你自己的加壳程序！(Packers to write himself, according to the document step by step, do your own packers!)

Hideseek可将秘密文件隐写到指定图片中，并可检测隐写信息，本文是对该软件的使用说明。(hide &seek to run the file through individual test run normally. Hidden secret documents can be written to the specified picture, and can detect steganographic message.)

VMPC加密解密算法。已对x86优化，其他平台也可用。(VMPC encryption and decryption algorithms. Has been optimized for x86, other platforms are also available.)
