VB来破解access密码
因为在网上看了一下 破解 access 密码 的几个 vb 函数,就拿出来和大家一起分享一下,教大家用 vb 来编写一个简单的工具吧。 打开 vb ,新建一个标准 EXE 工程,添加 3 个 label 控件, 3 个 text 控件, 2 个 command 控件,做出如图 1 所示的界面。 要 破
打开vb,新建一个标准EXE工程,添加3个label控件,3个text控件,2个command控件,做出如图1所示的界面。

要破解access的密码需要用到下面几个函数:GetFileName,FileExists,FileName,GetStrFromBuffer,GetAccessPwd,GetPwdDirect,Hex2ByteA,LoGetEncryptStr,LoGetKey。
因为这些函数都不是Windows API函数,所以需要我们进行自定义。点击“工程”,添加一个模块,如图2,

把函数定义写进去,由于代码过长,我就不一一例举了。
接下来大家请看窗体部分的代码:
Private Sub path_Click()
Text1.Text = GetFileName(True)
End Sub
Private Sub pass_Click()
Dim sFileAs String
Dim sPasswd As String
Dim sVersion As String
sFile = Text1.Text
sPasswd = GetAccessPwd(sFile, sVersion, True)
If gbExit Then Exit Sub
Text2.Text = sVersion
Text3.Text = sPasswd
End Sub
当点击“选择路径”时,就会调用GetFileName函数来取得目标数据库的路径,然后赋值给Text1。当点击“破解密码”时,则调用GetAccessPwd函数来取得数据库的密码,把数据库的版本号传到Text2,把密码传给Text3。
现在,这个小东西已经弄好了,我们来生成EXE文件看看它的效果吧,如图3。
