CRC32

里面主要是DES算法的 vc++实现的，在VC6.0下调试通过-DES algorithm which is mainly vc++ to achieve, in the VC6.0 debugger through the next

应用背景在这篇文章中，我将介绍一个简单的源代码，让您的数字签名PDF文档和修改它的元数据。我会用优秀的 自由港；iText  ；图书馆：itextsharp，可以下载 ；这里。你需要2008个视觉工作室能够打开和建设该项目。关键技术itextsharp提供了很多有趣的功能，创建和操纵PDF文件，但在这篇文章中，我们将只使用数字签名功能。我也会用一些功能来操作# PKCS 12证书。你唯一需要知道的是，我们的数字签名将使用从蛋白提取私钥# 12证书。

音频的水印加入算法，采用matlab实现-joined audio watermarking algorithm, using Matlab to achieve

Cryptmount是对Linux系统下的文件系统以及用户设备、文档等进行加密的系统.-Cryptmount of the Linux system and the file system of user equipment. Documents and other encryption systems.

程序使用C++展示相当强的XOR加密。 当它unencrypting文件时，包括EOF验错和自动侦查。程序很好被提供并且做在串类建立的好用法。-Program Uses C++ to Demonstrate A Fairly Strong XOR Encryption. Includes EOF error checking and automatic detection of when it is unencrypting a file. Program Is Documented Well And Also Makes Good Use of the Built In String Class.

base64加密 -base64 encrypted base64 encryption

GetDiskSerial.DLL 是一个标准的Windows动态链接库，它能够让您在你的程序中简单地获取硬盘出厂序列号。理论上讲，硬盘出厂序列号在全球都是唯一的，所以您可以利用此序列号来产生软件的机器码。 GetDiskSerial.DLL 已经成功的应用在各种流行的开发语言，比如Delphi, C++Builder, C#, Visual C++, Visual Basic, Visual Basic.NET, PowerBuilder, Visual Foxpro, Clarion。产品包里已经包含以上开发语言的调用实例。 -GetDiskSerial.DLL is a standard Windows dynamic link library, which allows you to program in your hard drive a simple access to the factory serial number. In theory, the hard disk factory serial number is unique in the world, so you can use this serial number to generate the software machine code. GetDiskSerial.DLL has successfully used in a variety of popular development languages, such as Delphi, C++ Builder, C#, Visual C++, Visual Basic, Visual Basic.NET, PowerBuilder, Visual Foxpro, Clarion. Product package already contains a call to an instance of the above development language.
