MD5加密算法得VisualC＋＋6.0源程序，直接调用里面的函数即可

rda加密源代码-The source code of RSA encryption algorithm

除了上面提到的压缩方法，你也可以调用VB的工具MakeCab.exe（在VB5setupkitkitfil32或VB98WizardsPDWizard目录下）生成.cab文件。先构造一个Directive 文件(*.ddf)，然后使用Shell命令调用MakeCAB /f excel.ddf就可以生成*.cab文件。关于Directive 文件的格式，可以参考MSDN Library中的《MakeCAB: A Compression and Disk Layout Tool》一文。 -addition to the above-mentioned methods of compression, you can call VB Tools MakeCab.exe (VB5 setupkit kitfil32 or VB98 Wizards PDWizard directory) production. Cab document. First constructed a Directive document (*. DDF), then use the Shell order call MakeCAB/f excel.ddf can generate*. cab documents. Directive on the document format, they can refer to the MSDN Library "MakeCAB : A Disk Compression and Layout Tool," a text.
