我的任务
分享C++ Builder做DES的加解密
最好是一个C++ Builder可以引用的文件，然后直接调用其中的加密函数进行加密，解密函数进行解密即可。
如有请告知如何使用？或发送E-MAIL：hateqing@163.com，谢谢赐教。

des代码网上大把，搜索一下就有了，怎么最近老是有人问我要。
包括d3des都可以找到的

[CODE c/c++]
DES算法加密解密控件for C Builder
可以将需要加密的文字加密成16进制或非16进制的字符串；也可以反过来解密之。
操作十分方便，只需放入本控件，然后调用4个加解密函数即可轻松完成！
Copy this directory to bcb working directory opening des.bpk and install.
Example:
String x,y;
x = WCDESComp1->EncryStrHex("I love CHINA","abcdefg");
y = WCDESComp1->DecryStrHex(x,"abcdefg") ;
ShowMessage("Encrypt \"I love CHINA\" is " x "\nDecrypt is \"" y "\"");
