RSA

测试对字符串的MD4。运行环境：vs2008 （注意选择“多字符”编译）-Testing of the string MD4. Operating environment: vs2008 (attention to the selection " multi-character" compilation)

1.本程序没有写密码更改,本程序的密码是MD5加密过的 2.默认登陆密码为 dmlt 3.更改密码可以在数据库里面操作,取得MD5加密的密码可以在Http://www.cmd5.com中取得 4.本程序解决了sql注入问题,在安全上大大提升 (1. This program does not write the password change, password, this procedure is MD5 encrypted 2. The default login password is dmlt 3. Change the password can be operated in a , get MD5 encrypted password can be Http: // www.cmd5.com achieved 4. this program solves the problem sql injection, greatly enhance the security )

VC++实现文件加密功能的源代码，这只是一个简单的例子，如果你感兴趣可以更加深入的研究一下。-VC file encryption function in the source code, this is just a simple example, if you are interested more in-depth study.

椭圆曲线的实现(ECC)，椭圆曲线算法是代数几何、数论等多个数学分支的一个交叉点，一直被人们认为是纯理论学科。而椭圆曲线密码体制，是基于椭圆曲线离散对数问题的一种公钥密码体制(Realization of elliptic curves (ECC), elliptic curve algorithm is algebraic geometry, a number of mathematical intersection of number theory and other branches, has been considered a purely theoretical discipline. The elliptic curve cryptosystem is based on elliptic curve discrete logarithm problem as a public-key cryptosystem)

这段代码适用于matlab的ECC加密。它包含ECC加密算法的所有必要活动；

MD5算法的详细介绍，很容易理解，给人豁然开朗的感觉-MD5 algorithm is a detailed description, it is easy to understand, gives a clear insight into feelings

sha256的签名算法，纯C实现，已验证正确，在控制台上直接运行即可，(sha256 signature algorithm, pure C implementation ，has been verified properly and can be run directly on the console.)
