GenerateKey

实现对单文件的DES加密解密，不限制大小，DES加密部分自写，非调用，用于学习DES原理。(The realization of the single document DES encryption and decryption, no limit to the size, DES encryption part self written, non call, for learning DES principle.)

基于vc++的音频加密软件的设计通过查阅资料对当今比较广泛使用的音频加密算法进行选择，并对其中的三种算法进行其性能方面的比较，找出其中加密性能较好(Audio encryption software design based on VC++through access to information is widely used for today s audio encryption algorithm to choose, and the three kinds of algorithms are compared, and its performance to find out one encryption)

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)

基于miracl大数库的椭圆曲线EC的签名算法的c语言实现(Database based on large numbers miracl elliptic curve signature algorithm EC for c-language implementation)

AES128bit加密算法。在PDF文档中有详细算法描述(AES128bit encryption algorithm. PDF documents are detailed in the algorithm description)

Base64的编码程序 基于VC++编写的(Base64 encoding program written with VC++)

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)

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.)
