Bat file

#1 Post by Marde » 27 Jul 2017 17:40

Hi

Can someone help me to create a .bat that makes my cmd ask for a login and password when the User or anyone else open it ? (is this possible?).

If the above isnt possible then a .bat dat makes the "echo" always "on" so that way everytime the cmd needs something, it will ask to the User.

Im using
Windows 8 Single Language
Sublime text editor

Thanks for anyone who read this :)

You need to store the linked MD5 Algorithm as "md5.bat".

Put this at the begining of the login section

Code: Select all

@echo off
color 4f
cls
set "psCommand=powershell -Command "$pword = read-host 'Enter 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 "%password%"=="Welcome" goto m
goto X
:X
cls
echo INCORRECT PASSWORD
echo ACCESS DENIED
pause
exit

:M
echo Welcome
Pause
cls
exit


Where the Password is Welcome put what you want the password to be

Kind Regards

and to hide the code compile the batch file into an exe file using batch to exe software that way no one can change the password or view it for that matter.

Hope this helps someone

Batch code can't be compiled. Bat2Exe programs just pack the script into something like a self-extracting archive or an installer. It has to be extracted in order to be executable.

That's wrong. At least during runtime you will find your original code somewhere in the Temp folder. (Besides of all the other possible side effects that I wrote a hundred times before.)

If you're storing your passwords in plaintext, you're doing it wrong.
Salt and hash your passwords

Incorrect it does not store the password it simply refers it it in the code nothing shows at run-time check it out

How it works is that it is written to the code inside the batch file then converted to a exe file which hides the code as exe files can not show the code.

so when run it looks for the code inside the batch file, Now i don't claim to have written the code but I know it works I have been writing code for a long time now, and have learned much about batch files as it was my Favorited subject I personally have written the ultimate batch file and it does everything you could possible what it to do. I love to learn new things and that is why I am passionate about the subject as I understand it so well

Kind Regards

But if the script is open long enough for a user to find it (like if the script asks for the user to input a password, for example), the original script can be found in the Temp folder and if you're storing the password in plain text behind an exe converter, it can easily be seen.

Nope. I told you how it works and ShadowThief already posted a screenshot. As long as you have commands in your code that wait for user interaction (like SET /P, CHOICE, PAUSE, ...) you have all the time in the world to search and find it on your hard drive (and usually you will find it in the Temp folder). I checked it out a hundred times. Furthermore you don't think of all the drawbacks and side effects caused by the fact that the script is executed in a different folder, caused by the fact that it is executed in WOW64 mode (on 64 Bit machines), caused by the fact that antivirus software might consider the created exe file as False Positive, etc.

OK I am no longer wasting any more time on this subject you clearly don't understand code here and are to ignorant and uneducated to understand how it works have it your way but the code works and well in my opinion noticed you cant answer any real batch coding questions here as I suspected you don't understand nothing about batch scripting.
