Batch file to convert text to md5sum value

Question

I need to create an windows "batch" file with following conditions. Convert the text to md5sum value I tried with below .bat file. But not working

@echo off

setlocal ENABLEDELAYEDEXPANSION

set hashmd5=$(echo -n welcome1 | md5sum | cut -c 1-32);

printpass=$printpass"#####MD5: echo.%%hashmd5 "\n"

Answer 1

Here's another version, also using certutil to generate the MD5 hash. It'll give you the MD5sum of a file or of a string argument, and can accept one line of input via the pipeline. This solution doesn't depend on an accompanying helper script.

@echo off & setlocal

set "plaintext=%~1"
set "file=%temp%\%~n0.tmp"
set md5=

if "%~1"=="/?" (
    echo Usage: %~nx0 file^|string
    echo    or: command ^| %~nx0
    echo;
    echo Example: set /P "=password" ^<NUL ^| %~nx0
    goto :EOF
)

if not defined plaintext set /P "plaintext="

if exist "%plaintext%" (
    set "file=%plaintext%"
) else for %%I in ("%file%") do if %%~zI equ 0 (
    <NUL >"%file%" set /P "=%plaintext%"
)

for /f "skip=1 delims=" %%I in ('certutil -hashfile "%file%" MD5') do (
    if not defined md5 set "md5=%%I"
)

2>NUL del "%temp%\%~n0.tmp"

echo %md5: =%

Just because I felt like the challenge, here's yet another version that can accept multiple lines via the pipeline, as well as input from file redirection. (It wasn't easy preventing StdIn.AtEndOfStream from prompting for keyboard input when the buffer was empty.)

@if (@CodeSection == @Batch) @then
@echo off & setlocal & goto main

:usage
echo Usage: %~nx0 file^|string
echo    or: command ^| %~nx0
echo    or: %~nx0 ^< file
echo;
echo Example: set /P "=password" ^<NUL ^| %~nx0
goto :EOF

:main
set "plaintext=%~1"
set "file=%temp%\%~n0.tmp"
set md5=

rem // check for input via the pipeline; timeout nearly instantly if none
start /b "" cscript /nologo /e:JScript "%~f0" "%file%" watcher
cscript /nologo /e:JScript "%~f0" "%file%"

if "%~1"=="" for %%I in ("%file%") do if %%~zI equ 0 goto usage
if "%~1"=="/?" goto usage

if not defined plaintext set /P "plaintext="

if exist "%plaintext%" (
    set "file=%plaintext%"
) else for %%I in ("%file%") do if %%~zI equ 0 (
    <NUL >"%file%" set /P "=%plaintext%"
)

for /f "skip=1 delims=" %%I in ('certutil -hashfile "%file%" MD5') do (
    if not defined md5 set "md5=%%I"
)

2>NUL del "%temp%\%~n0.tmp"

echo %md5: =%
goto :EOF

@end // end Batch / begin JScript hybrid code

var fso = WSH.CreateObject('scripting.filesystemobject');
if (WSH.Arguments.Length > 1) {
    WSH.Sleep(1);
    if (!fso.FileExists(WSH.Arguments(0)))
        WSH.CreateObject('WScript.Shell').Exec('taskkill /im "cscript.exe" /f');
} else if (!WSH.StdIn.AtEndOfStream) {
    var file = fso.CreateTextFile(WSH.Arguments(0), 1);
    file.Write(WSH.StdIn.ReadAll());
    file.Close();
}
