用VC6.0实现的，运用NTL大整数库实现RSA的加密和解密算法，具有较高的效率！(VC6.0 achieved by applying NTL large integer achieve RSA encryption and decryption algorithms, with high efficiency!)

MD5算法描述（略）。 设计一个模拟的系统用户安全登录界面，采用MD5算法实现用户登录口令的安全认证。要求模拟界面至少具有用户口令文件的注册和用户登录时输入的口令是否正确的结果提示两个功能。 (MD5 algorithm description (abbreviated). The design of a simulation system security log user interface, using MD5 algorithm users log on password security authentication. Analog interface requirements at least a registered user password files and user login password is entered when the correct results suggest that the two functions.)

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.)

信息加密原码，用md5算法实现，开发语言：c(original message encryption code used md5 algorithm, the development of language : c)

以DES加密算法为例理解对称密码算法，用计算机模拟DES加密解密算法。 (DES encryption algorithm as an example to understand the symmetric cipher algorithm, using computer simulation DES encryption and decryption algorithms.)

说明：  用于数字、密码等字符的加密和解密，用于数字、密码等字符的加密和解密，用于数字、密码等字符的加密和解密，用于数字、密码等字符的加密和解密(For numbers, passwords, encryption and decryption of characters for numbers, passwords, encryption and decryption of characters for numbers, passwords, encryption and decryption of characters for numbers, passwords, encryption and decryption of characters)

RSA算法的解密和加密，用扩展的欧几里得算法求乘法逆元(rsa)

说明：  信息安全相关，经典加密算法A5，通过编译(Information security-related, classic encryption algorithm A5, through compiler)

基本的DES加密算法，可以实现一些基本的功能，但是大型计算不适合(The basic DES encryption algorithm)

加密程序,很好用。亲自验证，完全正确。希望下载。(we can add and unadd a picture correctly.welcom to download.)
