AES和DES加密算法，提供了两个函数可以AES或D。

此为国外转载函数，可将任意字符转换为md5 16为字符加密形式，而且为不可逆转换。-reproduced here for foreign functions, arbitrary characters can be converted to 16 md5 encrypted form of characters, but also to irreversible change.

将其他文件隐藏在BMP图像中！好-other documents hidden in BMP image! Good

将密钥添加到文件尾部的例子- Increases the key to the document rear part example

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.
