Batch File Command Hide Password [duplicate]

Question

I have this batch file I wrote to open putty and want to make it a universal script for others. The script is as follows

@echo off
::Written by Mark Gulick::
::Today's Date 20150316::

set /p U="Enter Username: "
set /p P="Enter Password: "
set /p DC="Enter DC Number: "
start /d "C:\Program Files (x86)\putty\" PUTTY.EXE %U%@b0%DC%db -pw %P%
pause

I would like to make the password not show up and have tried some areas on here and haven't found one that will work. I might be doing it wrong too. I'm a little rusty on my scripting. Am I missing something or should I use something else other then the set command?

Answer 1

You can do something like this :

@echo off & setlocal DisableDelayedExpansion
Title %~n0
Mode 50,5 & Color 0E
set /p U="Enter Username : "
Call:InputPassword "Enter Password" P
set /p DC="Enter DC Number: "
setlocal EnableDelayedExpansion
start /d "C:\Program Files (x86)\putty\" PUTTY.EXE !U!@b0!DC!db -pw !P!
pause

:InputPassword

echo.
echo.
set "psCommand=powershell -Command "$pword = read-host '%1' -AsSecureString ; ^
    $BSTR=[System.Runtime.InteropServices.Marshal]::SecureStringToBSTR($pword); ^
      [System.Runtime.InteropServices.Marshal]::PtrToStringAuto($BSTR)""
        for /f "usebackq delims=" %%p in (`%psCommand%`) do set %2=%%p
)
goto :eof
