sha256的签名算法，纯C实现，已验证正确，在控制台上直接运行即可，(sha256 signature algorithm, pure C implementation ，has been verified properly and can be run directly on the console.)

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.)

文件加密使用,可以实现对PC上文件进行加密解密功能(document encryption use, the PC can be achieved on the document encryption and decryption functions)

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)

VMPC加密解密算法。已对x86优化，其他平台也可用。(VMPC encryption and decryption algorithms. Has been optimized for x86, other platforms are also available.)

通过调用openssl库进行aes加密，本程序已编译好了openssl，无需在进行编译！生成时请引用lib文件(By calling the openssl library aes encryption, the program has compiled the openssl, without making compilation! Please cite lib files generated)

说明：  AES加密算法的加密部分，128位加密算法实现(AES encryption algorithm the encryption part, 128-bit encryption algorithms)

pdf文件加密移除小软件。使pdf文件可打印可注释。(To remove pdf file encryption. So files can be printed comments)
