问题
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?

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
Cls
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

This post on DOSTips references a post here by MC ND, but I can't find the original, so here it is again. Whenever you want to get a password and mask the input, simply call :getPassword target_variable input_prompt where target_variable is the name of the variable you store the password in and input_prompt is whatever you show the user to prompt them to enter their password.
@echo off
set /p "user_name=Enter username here:"
call :getPassword user_password "Enter password here: "
:: The user's password has been stored in the variable %user_password%
exit /b
::------------------------------------------------------------------------------
:: Masks user input and returns the input as a variable.
:: Password-masking code based on http://www.dostips.com/forum/viewtopic.php?p=33538#p33538
::
:: Arguments: %1 - the variable to store the password in
:: %2 - the prompt to display when receiving input
::------------------------------------------------------------------------------
:getPassword
set "_password="
:: We need a backspace to handle character removal
for /f %%a in ('"prompt;$H&for %%b in (0) do rem"') do set "BS=%%a"
:: Prompt the user
set /p "=%~2" <nul
:keyLoop
:: Retrieve a keypress
set "key="
for /f "delims=" %%a in ('xcopy /l /w "%~f0" "%~f0" 2^>nul') do if not defined key set "key=%%a"
set "key=%key:~-1%"
:: If No keypress (enter), then exit
:: If backspace, remove character from password and console
:: Otherwise, add a character to password and go ask for next one
if defined key (
if "%key%"=="%BS%" (
if defined _password (
set "_password=%_password:~0,-1%"
set /p "=!BS! !BS!"<nul
)
) else (
set "_password=%_password%%key%"
set /p "="<nul
)
goto :keyLoop
)
echo/
:: Return password to caller
set "%~1=%_password%"
goto :eof

batch-file's cannot do this alone, but if you're running batch that means you're likely on windows, and automatically have VBScript installed. You can use this to get a password with masking:
randomThing.bat
echo Blah blah blah...
:: Call a vbscript file with the outputs being set as a variable
for /f "usebackq tokens=*" %%r in (`wscript "password.vbs"`) do set retPass=%%r
:: Write back the input for example's sake.
echo What you typed in: %retPass%
password.vbs
'Call this script from a batch file to input a masked password
set objPassword = createObject("scriptPW.password")
wScript.stdOut.write "Input Password:"
strPassword = objPassword.getPassword()
wScript.echo strPassword
Note I'm answering this on mobile, and as such cannot test if this method still works. However it gets the main idea across.
