aes256加密解密算法，256bit秘钥，配有例子 。(aes256 encrypt and decrypt)

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加密操作的窗体应用程序。经过加密的文件以及密钥文件都是文本文件。给出关键类类图、整个应用程序的结构描述文档、关键模块流程图、较详细的接口文档、所有源代码。对应用程序进行测试，对测试结果进行分析研究，进而对应用程序进行改进，对关键算法进行尽可能的优化，最终得到一个在windows运行的可以用指定密钥对任意文件进行RSA加密并可解密的完整应用程序，和一些相关的可移植组件。 (RSA algorithm analysis application, appraisal document RSA encryption algorithm application of the feasibility and significance. Practical design of a complete set of documents RSA encryption solution to achieve specific coding. RSA algorithm to study conventional RSA algorithm, using C to achieve RSA encryption algorithm library. and 32% Packaging windows platform components. In. Net platform invocation components can be achieved for arbitrary document RSA encryption operation Window applications. After an encrypted file and key documents are text documents. Class is the key category map, the entire application document describes the structure, the key modules flowchart, more detailed interface documentation, All source code. Application procedures for conducting tests on the test results)
