Prompt for Passwords

 

ScriptPW.Password
VBScript Code:
strPw = Password( "Please enter your password:" )
WScript.Echo "Your password is: " & strPw

Function Password( myPrompt )
' This function hides a password while it is being typed.
' myPrompt is the text prompting the user to type a password.
' The function clears the prompt and returns the typed password.
' This code is based on Microsoft TechNet ScriptCenter "Mask Command Line Passwords"
' http://www.microsoft.com/technet/scriptcenter/scripts/default.mspx?mfr=true

    ' Standard housekeeping
    Dim objPassword

    ' Use ScriptPW.dll by creating an object
    Set objPassword = CreateObject( "ScriptPW.Password" )

    ' Display the prompt text
    WScript.StdOut.Write myPrompt

    ' Return the typed password
    Password = objPassword.GetPassword()

    ' Clear prompt
    WScript.StdOut.Write String( Len( myPrompt ), Chr( 8 ) ) _
                       & Space( Len( myPrompt ) ) _
                       & String( Len( myPrompt ), Chr( 8 ) )
End Function
Requirements:
Windows version: XP, Server 2003, or Vista
Network: N/A
Client software: .NET Framework for Windows 98, ME, NT 4 & 2000
Script Engine: WSH, CSCRIPT.EXE only
Summarized: Works in Windows XP or later, only in CSCRIPT.EXE (uses StdOut).
Should also work in older Windows versions with .NET Framework installed (look for scriptpw.dll), only in CSCRIPT.EXE.
Doesn't work in Windows 95, nor in Windows 7.
