unpack encrypted file using passwords list

[KozakMak]

there is a password-protected zip archive
there is a txt file with a list of passwords

How can I quickly go through this list and unpack the archive?

You could use 7-Zip with a CMD file like this:

Code: Select all

@echo off
setlocal enabledelayedexpansion
cls

set archive=%1
set szexe="C:\PathTo\7-Zip24\7z.exe"
set pw_list="C:\PathTo\7-Zip24\passwords.txt"

for /F "usebackq delims=" %%P in (%pw_list%) do (
	%szexe% t -p%%P %archive% > nul 2>&1
	if !errorlevel! EQU 0 (echo Password: && echo %%P && pause && goto :eof)
)
pause

Put the CMD file on a button with parameter "%P%N"

You could use 7-Zip

will https://www.7-zip.org/a/7zr.exe be enough?

set szexe="C:\PathTo\7-Zip24\7z.exe"

without set will be better... using path

set pw_list="C:\PathTo\7-Zip24\passwords.txt"

can you make that .txt = archive name? e.g for encryptedarchive.zip searching encryptedarchive.txt in same folder

7zr only supports 7z files, you could use 7za.exe for more formats.

I'm note quite sure what you mean. Do you have the 7-Zip path in your "path" environment variable? Then you could use 7za.exe instead of %szexe%, see "rem" line below.
Or do you have the 7za.exe in the same folder as the archives? Then you could use the second "rem" line.

Use this CMD file with parameters

Code: Select all

%P%N

and adjust the szexe path.

Code: Select all

@echo off
setlocal enabledelayedexpansion

set archive=%1
set pw_list=%~dpn1.txt

set szexe="c:\PathTo\7za.exe"
 
for /F "usebackq delims=" %%P in ("%pw_list%") do (
	%szexe% l -p%%P %archive%  > nul 2>&1
	rem or 7za.exe l -p%%P %archive%  > nul 2>&1
	rem %~dp17za.exe l -p%%P %archive%  > nul 2>&1
	if !errorlevel! EQU 0 (echo Password: && echo %%P && pause && goto :eof)
)
pause

For debugging:

Code: Select all

setlocal enabledelayedexpansion

set archive=%1
set pw_list=%~dpn1.txt

set szexe="c:\PathTo\7za.exe"
 
for /F "usebackq delims=" %%P in ("%pw_list%") do (
	%szexe% l -p%%P %archive%
	rem or 7za.exe l -p%%P %archive%
	rem %~dp17za.exe l -p%%P %archive%
	if !errorlevel! EQU 0 (echo Password: && echo %%P && pause && goto :eof)
)
pause

* Edit: replaced t(est) with l(ist) argument. Should be faster.
