I use winrar.
This can be easily done using PowerShell, and rar.exe which is part of WinRAR. Just edit the first three variables below according to your needs and run the script. You don’t even need to save it as a script, just copy-paste the code into a PowerShell window, you can use the arrow keys to edit the variables (or edit it using notepad if you like) and then press enter when you’re ready to run the script.
$winrar = "C:\Program Files\WinRAR\Rar.exe"
$passlist = @("pass1", "pass2", "pass3", "pass4")
$folder = "C:\Path\To\Folder"
cd "$folder"
foreach($file in (dir *.rar).Name) { "Checking $file..."; foreach($pass in $passlist) { .$winrar t -p"$pass" "$file" *>$null ; if($LASTEXITCODE -eq 0){ " → Password for $file is $pass"; break }}""}
This would give you an output which looks like:
Checking file1.rar...
→ Password for file1.rar is pass1
Checking file2.rar...
→ Password for file2.rar is pass2
Checking file3.rar...
→ Password for file3.rar is pass3
If there’s something you don’t understand in the code above, lemme know - happy to explain further. :)
Something like this should work on linux or mac. On windows you’ll probably need to use wsl or convert it to powershell if you can’t install the dependencies natively. The script requires bash, unrar, and find.
#!/usr/bin/env bash
while read -r rarfile; do
while read -r password; do
if unrar t -p"$password" "$rarfile" >/dev/null 2>&1; then
echo "$rarfile $password"
break
fi
echo "$rarfile password not found"
done < /path/to/passwords.list
done < <(find /path/to/rars -type f -iname '*.rar')
Ask chat gpt! It will not only tell you exactly how, and build the script for you, you will also be able to add ask custom questions when things go wrong, or get other methods.
Chatgpt is a google search on steroids.
Edit: yall can downvote gpt all you want, it took me 3 minutes to do it locally and it provided a safe and valid script.

While it might be close to good enough for casual scripts, it is much better to use existing tools for performance critical applications, such as brute forcing passwords.
Lmao. Is this not a “casual script”? The dude wants to try a handful of passwords, not brute force a leaked db.
I believe not. The question states “keywords” so it seems they want to try combinations of words they commonly used. And it makes a huge difference if the script can try one password per second or dozens/hundreds/more.
What search term do you use? I’ve just tried and it said it can’t help with that.
Me: I need to write a powershell script on windows to open a password protected zip file for which I have the password
Gpt:
Sure! Here’s how you can create and use a PowerShell script to unzip a password-protected zip file on Windows:
First, make sure you have the required module installed. You can use Expand-Archive for normal zips, but for password-protected zips, we will leverage the 7-Zip utility. You can download it from here.
After installing 7-Zip, you can use its command line interface, 7z.exe, usually located in C:\Program Files\7-Zip.
Create a PowerShell script named UnzipProtected.ps1 with the following content:
[Parameter(Mandatory=$true)]
[string]$zipFilePath,
[Parameter(Mandatory=$true)]
[string]$destinationPath,
[Parameter(Mandatory=$true)]
[string]$password
)
$sevenZipPath = "C:\Program Files\7-Zip\7z.exe"
if (-not (Test-Path $sevenZipPath)) {
Write-Error "7-Zip not found at $sevenZipPath. Please install it or adjust the path."
exit 1
}
& $sevenZipPath x -p$password -o$destinationPath $zipFilePath
if ($? -eq $true) {
Write-Host "File unzipped successfully!"
} else {
Write-Error "Failed to unzip the file."
}```
> Now, you can use the PowerShell script to unzip the password-protected file:
```.\UnzipProtected.ps1 -zipFilePath "path_to_your_zip_file.zip" -destinationPath "path_to_extract_folder" -password "yourpassword"
Replace the placeholders with the appropriate paths and password.
Note: Make sure you execute the PowerShell script with appropriate permissions (Run as Administrator if required). Also, ensure that your execution policy allows you to run scripts (Set-ExecutionPolicy RemoteSigned or Set-ExecutionPolicy Unrestricted but be aware of the security implications). Always handle passwords securely.
Me: Can you have it loop through a handful of my passwords
Gpt:
Certainly. We can adjust the script to loop through a list of passwords until the correct one is found or the list is exhausted.
Modify the UnzipProtected.ps1 script as follows:
[Parameter(Mandatory=$true)]
[string]$zipFilePath,
[Parameter(Mandatory=$true)]
[string]$destinationPath,
[Parameter(Mandatory=$true)]
[string[]]$passwords
)
$sevenZipPath = "C:\Program Files\7-Zip\7z.exe"
if (-not (Test-Path $sevenZipPath)) {
Write-Error "7-Zip not found at $sevenZipPath. Please install it or adjust the path."
exit 1
}
$success = $false
foreach ($password in $passwords) {
& $sevenZipPath x -p$password -o$destinationPath $zipFilePath
if ($? -eq $true) {
Write-Host "File unzipped successfully with password: $password"
$success = $true
break
}
}
if (-not $success) {
Write-Error "Failed to unzip the file with provided passwords."
}
You can now use the script to try multiple passwords:
.\UnzipProtected.ps1 -zipFilePath “path_to_your_zip_file.zip” -destinationPath “path_to_extract_folder” -passwords @(“password1”, “password2”, “password3”)
Replace the placeholders with the appropriate paths and the list of passwords you want to try.
Note: Be very careful with this kind of script, especially if you’re using it with real passwords. It’s essential to handle passwords securely, and not to keep them in clear text or hardcoded in scripts. Use this approach only in a controlled and secure environment.
Obviously this is an example, but you can keep talking to it to refine how you want the search to happen. If there’s an error, tell gpt what happened, or which step you aren’t able to do and it will walk you through that as well!
Was hard to copy paste over on my phone so format is a bit messed up, but you get the idea
