    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. :)

    Is there a way to call the unrar command via command line and pass the password as a parameter? There should be.

    If there is not with winrar, try the 7zip commandlet for powershell, that should definitely be able to do what you want.

    Write a quick skript that reads your passwords from a text file into a variable, use a foreach-object loop to iterate over the variable and each time call the unrar command and use the current password.

    Not sure if this is elegant, but that’s the first thing that comes to my mind.

      Isn’t that the tool that let’s you brute force weak encrypted containers? I remember saving my sister that got a pin secured container and the pin was coming over mail/on a different channel (she needed it as fast as possible)…

      Well it was a 4 digit pin and my very old notebook took a few hours. Even less if my sister would have told me that it was a 4 digit nummeric pin and not alphanumeric.

      So yea. Hashcat will be your friend. Afaik can also take guesses.

        How fast it is depends entirely on the application.

        But yes, it can do all sorts of fancy things like rule expansions, word combinations and custom character brute force.

        It sits in that conceptual corner.

        Hashcat is the standard password recovery tool. It supports a whole bunch of applications. It’s fast and optimized. It’s by definition the right tool for the job.

        Kali is a Linux distribution that incorporates a bunch of security related tools, including hashcat. But you can just download the hashcat program and run it on windows or Mac.

  • 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.

        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!

      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.
