Easy Zip FIle Password Cracker

After searching today for a free password cracking application for zip file, I decided to make my own. All that is required is 7-zip, a decent word list, and this trusty batch file.

# usage zip_crack.bat
#note: Does not handle passwords with spaces.
@echo off
SET targetfile=%2

SETLOCAL ENABLEDELAYEDEXPANSION

FOR /F %%i IN (%targetfile%) DO (
echo %%i

7z.exe e -y -p"%%i" %1
IF !ERRORLEVEL! == 0 (
ECHO %%i >> CREDS.txt
)


)
