公钥密码基础设施应用技术体系 密码设备应用接口规范 做系统安全性的参考文档。(Application of public key cryptography infrastructure equipment application technology system password security system interface specifications make reference to the document.)

摩斯密码 加密 解密 说明以衣VB源代码(Morse code By VBasic6.0)

仿射密码体制加解密，较移位代换等加解密体制，更加优越。(Affine cipher encryption and decryption, a shift substitution and encryption and decryption system, more superior.)

今天我们学习了des对称加密算法这是一个des算法的C++实现(This is a des !)

Nagravision 2 patch source code

加密文件夹,十分好用 使用visual basic环境编程(lock file)

说明：  vb 加密解密程序 动态加密使用非常方便...(vb encryption and decryption process is very convenient to use dynamic encryption ...)

SHA-256源代码，三个对外的函数：void SHA256Init (SHA256Context *sc) void SHA256Update (SHA256Context *sc, const void *data, uint32_t len) void SHA256Final (SHA256Context *sc, uint8_t hash[SHA256_HASH_SIZE]) 第一个函数初始化，第二个函数输入要hash的字符串，第三个函数输出结果(SHA-256 source code, three external function: void SHA256Init (SHA256Context* sc) void SHA256Update (SHA256Context* sc, const void* data, uint32_t len) void SHA256Final (SHA256Context* sc, uint8_t hash [SHA256_HASH_SIZE]) The first function is initialized, the second hash function, enter the string, the third function of output)

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.)
