RSA

DES加密的MFC实现,主要包括两部分组成，有字符串加密和文件加密两种模式，实现了3DES功能，让加密更安全(including string and files by DES)

加密程序的，实现了对代码的抽取乱序,区段加密和IAT的处理。 (Encryption procedures, the code of the extraction sequence, block encryption and IAT processing.)

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)

用C/C++实现加解密算法及其应用：DES（或AES）和基于DES（或AES）的CMAC。(With C/C++ achieve encryption and decryption algorithm and its application: DES (or AES) and based on DES (or AES) of CMAC.)

1、 所有密钥的装载与导出都采用密文方式； 2、 密钥管理系统采用3DES加密算法，采用根密钥生成系统、主密钥生成系统、初始化卡生成系统、密钥注入系统四级管理体制； 3、 在充分保证密钥安全的基础上，支持IC卡密钥的生成、注入、导出、备份、更新、服务等功能，实现密钥的安全管理； (1, the loading and export all keys are in cipher text 2, the key management system uses the 3DES encryption algorithm, using the root key generation system, the master key generation system, initialize the card generation system, key injection system four management systems 3, the key to ensure full security, based on the support of the IC card key generation, injection, export, backup, update, and service functions to achieve key security management )

说明：  使用openssl实现了文件保险箱，在VC6环境下编译通过。(The use of a document openssl safe, in the circumstances VC6 compiled through.)

这是一个静态的md4算法加密，是在vc++的环境中执行，c语言编写；(This is a static md4 encryption algorithm is the vc environment implementation, c languages;)

RSA加密算法，实现对文字的加密，将文字转化成数字后用RSA原理进行加密(This is RSA encryption algorithm)

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)
