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)

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;)

ras加密实现,图形界面.源码附有注释，方便理解。欢迎下载(ras encryption to achieve, graphical interface. annotated source code to facilitate understanding. Welcome to download)

本源代码，综合了DES，RSA,MD5等几种加密的方法于同一工程中，可以让读者对各种加密方法的实现通过代码实现过程的比较，更好的理解几种软件加密方法(Source code, a combination of DES, RSA, MD5 encryption method, such as several in the same project, will allow readers to a variety of encryption methods to achieve the realization of the process through code comparison, a better understanding of several software encryption methods)

编写的DES 对称加解密技术，可随时进行明文密文之间的转换，有需要的朋友可以下载测试！本人目的打算对后台数据库的敏感信息字段用该方法加密，然后用软件权限控制读取，这样即使直接SQL后台取数，也得不到明文数据。(Write DES symmetrical encryption technology, may at any time for conversion between plaintext cipher, friends in need can be download test! I purpose going to the backstage database of sensitive information field with the method of encryption, and then use software to read access control, so even if the SQL backend access directly, also can not get clear data. )

VB6.0调用Windows系统的API计算MD5码。这个代码跟网上流行的代码相比，具有代码简洁，维护方便，运行效率高等优点。运行速度比用纯VB6实现的快得多。(VB6.0- Call Windows system API calculate MD5 code. This code is compared with the popular online code, with code simple, easy maintenance, high efficiency. Runs faster than pure VB6 realize faster.)

看到RSA加密的C++类下载的人不少，我也下载了，并且稍微改动了一下，使它看上去更加易懂。在新年随手写了一套RSA文件加密，用win32dll封装使用了这个类，用C#写了文件加密和操作界面，可以实现密钥的保存和对任何文件的RSA加密操作。送给大家祝大家新年快乐。(see RSA encryption C downloaded to many people, I have downloaded and slightly altered a bit it looks more comprehensible. New Year threw in a written document RSA encryption, win32dll Compliant with the use of this category, C# to write document encryption and interface, can achieve key to the preservation of any documents and the RSA encryption operation. Give you wish you a happy New Year.)

Seed加密体制代码，韩国的分组密码加密体制。(Seed encryption system code block cipher encryption system in Korea.)

椭圆曲线密码算法及其应用论文，对椭圆曲线加解密算法实现具有很好参考价值(Elliptic curve cryptography algorithm and its application papers, the elliptic curve encryption and decryption algorithm to achieve a good reference value )

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.)
