分析RSA算法的应用现状，论证文件加密应用RSA算法的可行性和意义。设计一套完整实用的RSA文件加密解决方案，具体编码实现。对RSA算法进行研究，从常规RSA算法出发，用C++实现RSA加密算法类库，并在32位windows平台封装成组件。在.Net平台引用此组件，实现可以对任意文件进行RSA加密 (Analysis of Application of RSA algorithm, file encryption application demonstration of the feasibility of RSA algorithm and significance. Design of a complete file encryption RSA practical solutions to achieve specific coding. Research on the RSA algorithm, starting from the conventional RSA algorithm using C++ class library to achieve RSA encryption algorithm, and in 32-bit windows platform components into a package. In. Net platform, referred to this component, the realization of arbitrary files on RSA encryption)

说明：  dsa数字签名 系统功能需求： 1.对文件进行签名，生成一个独立于原文的签名文件； 2.可以对文件进行签名，在文件后追加签名信息； 3.具有密钥管理的功能，比如密钥的生成、导入、导出； 4.可以对word文档实施操作，对word文档的内容进行签名； 5.能够比对已经实施的签名，防止进行重复的签名，以防止重放攻击； 6.可以对已经签名的文件进行单独的源文件和签名信息的分离操作。(DSA digital signature System functional requirements: 1. Sign the document and generate a signature file independent of the original text. 2. The document can be signed and the signature information can be added after the document. 3. It has the function of key management, such as key generation, import and export. 4. Word documents can be operated and the contents of Word documents can be signed. 5. Ability to compare existing signatures and prevent duplicate signatures to prevent replay attacks; 6. It is possible to separate the source file from the signature information of the signed file.)

VB文件加密器（异或加密）,有需要的就下载吧。(VB file encryption (XOR encryption), there is a need to download it.)

说明：  鉴于语音信号的“即时性 ”特点 ,在分析了混沌掩盖、混沌调制进行加密利弊的基上 ,构造了一种混沌切换加密方案 ,对语音进行了更安全有效地加密.(DESIGNOFVOICEENCRYPTIONCOMMUNICATIONSYSTEMBASEDONCOMPUTERNETWORK)
