文字加密器解密

‘壹’ 文件加密器的密码忘记了，怎么解密啊

以压缩文件为例，解决方法：

1、首先下一款文件密码破解工具，解压并双击运行其中的“RARPasswordUnlocker.exe”程序，即可启动WINRAR压缩文件密码破解程序。

‘贰’ 运用VB对文字进行加密解密

'这是我从网上找到的一段加密解密的代码，很不错，应该符合要求。
'文本框的multiline属性是用来设置是否可以接受多行文本，只能在窗体上手工设置。
'文本框的scrollbars属性是用来设置是否有垂直和水平滚动条的，也只能在窗体上手工设置。
'keyAscii不清楚是作什么用的。
'两个StrConv函数用的太好了，我没想到能处理的这么简单。
