介绍如何对共享软件加密。针对菜鸟！文档！

DES算法的C语言实现，大家可以参考一下。-DES algorithm to achieve the C language, we can reference.

vc环境下的pgp源码，pgp是目前很流行的一种加密算法，非常安全，正在发展中-vc environment of pgp source, pgp is a very popular encryption algorithm, very safe, developing

《DES算法的介绍和实现》配套源代码- "DES Algorithm Introduction And Realization" necessary source code

DES(Data Encrypton Standard) 算法的实现网上已经有很多，本人在此讲述的是在DES算法加密过程中如何查看16迭代过程中生成的Ki,Li,Ri,Fi,Si等，这样可以当做一个DES加密对照器，这样可以方便的发现你在加密过程中出现的错误! -DES (Data Encrypton Standard) algorithm has been achieved online many, I would like to speak on is the DES encryption algorithm to see how the process 16 iterative process of generating Ki, Li, Ri, Fi, Si, etc., can serve as a control device DES encryption, this can easily find you in the process of encryption the mistakes!

汇编程序写的Hash校检程序，分享源码，支持SHA1和MD5两种，支持拉拽，支持剪切板的复制和比对，有进行条，自动计算耗时 （使用了不太精确的计时器），速度还是可以的，大概就这样。 

实现BASE64编码-achieve BASE64 encoding

一个完整的des演示程序 ，在linux下编译通过-Des a complete demonstration of the procedures adopted in the compiler under linux

C#程序来实现生成多项式的循环冗余校验,通过修改能校验多项式-C# program to implement the cyclic redundancy check generator polynomial, by modifying the polynomial can check

利用PGP加密技术保护电子邮件安全,很不错的-The use of PGP encryption technology to protect e-mail security, very good
