des经典加密算法，实现数据交互过程中的保密(des classical encryption algorithm, data confidentiality during the interaction)

二进制文件操作工具 可以对二进制文件合并、分拆、加密、解密的工具，再对两个可执行文件进行合并后，显示第一个文件的信息，并且正常使用，第二个被忽略。(Binary file binary file manipulation tools can merge, split, encrypt, decrypt tool, and then the merger of two executable files, show the first file, and normal use, the second is ignored.)

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.)

带MD5摘要计算的登录程序,实现部分功能模块和部分界面(MD5 Abstract calculated with log procedures)

今天我们学习了des对称加密算法这是一个des算法的C++实现(This is a des !)

椭圆曲线加密算法，设置服务器一步的源代码(elliptic curve encryption algorithm, the step to set up the server source code)

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.)

AES加密，并完成基于AES的CAMC操作(AES encryption and the AES operation is completed based on CAMC)

说明：  一个移位加密算法的源代码，跟大家交流一下。(a shift encryption algorithm source code sharing with you what.)

实现透明加密,驱动模型，文件过滤系统介绍(To achieve transparent encryption, drive model, document filtering system introduced)
