How to assign password to secure string in VB Scri

I have a script comprising of batch files that generate powershell scripts. I've taken it upon myself to accomplish the same task via VB Script. So far I've assigned most of the info I need to strings. But I would like to have a prompt for a password that is stored as a secure string and can be outputted to a text file for later use in further scripts. So far the only code I've found doesn't work I think perhaps because it was intended for VB rather than VBS. Any help greatly appreciated.

The powershell code previously used was.

    echo Please enter admin credentials (This will be stored in a secure string:
    powershell -Command "& { read-host -assecurestring | convertfrom- securestring | out-file C:\S3BS\reports\input.txt; } "

If you are executing the VBScript via cscript.exe something like;

cscript.exe /nologo "test.vbs"

You can use the WScript object to access the StdIn (for input) and StdOut (for output) streams to the command window using a script like this;

Function PromptForInput(prompt)
  Dim prog : prog = WScript.Fullname
  If LCase(Right(prog, 12)) = "\cscript.exe" Then
    Call WScript.StdOut.WriteLine(prompt & " ")
    PromptForInput = WScript.StdIn.ReadLine()
  Else
    Call Err.Raise(vbObjectError + 5, "Must be called from cscript.exe")
  End If
End Function

Dim input
input = PromptForInput("Did you wish to continue? [Y/N]")
Select Case UCase(input)
Case "Y", "N"
  Call WScript.StdOut.Writeline("You chose: " & UCase(input))
Case Else
  Call WScript.StdOut.Writeline("Invalid option!")
End Select

Output:

Did you wish to continue? [Y/N]
y
You chose: Y

You can adapt it to prompt for passwords but be aware that the input is not hidden so all the characters typed are visible in the command window until it's closed.

I think this function PasswordBox can help you, just give a try ;)

' Just an example of how to use the function
 '
 wsh.echo "You entered: ", _
          Join(PasswordBox("Enter UID and password", _
               "Testing"), ", ")

You can use this small code with powershell and batch

@ECHO OFF
Title Type a password with powershell and batch
:CheckPassword
Mode con cols=50 lines=3
cls & color 0A & echo.
set MyPassword=Hackoo
set "psCommand=powershell -Command "$pword = read-host 'Enter your password' -AsSecureString ; ^
    $BSTR=[System.Runtime.InteropServices.Marshal]::SecureStringToBSTR($pword); ^
        [System.Runtime.InteropServices.Marshal]::PtrToStringAuto($BSTR)""
for /f "usebackq delims=" %%p in (`%psCommand%`) do set password=%%p
if %MyPassword%==%password% (Goto:Good) else (Goto:Bad)
exit/b
::***********************************************************************************************
:Good
Cls & Color 0A
echo(
echo                   Good Password
TimeOut /T 2 /NoBreak>nul
Exit
::***********************************************************************************************
:Bad
Cls & Color 0C
echo(
echo                   Bad password
TimeOut /T 1 /NoBreak>nul
Goto:CheckPassword
::***********************************************************************************************
