Forgot the password for my old RAR files, Want to try the passwords/keywords which I frequently use. How can I try them at once rather than typing them every single time for every .rar file?

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.

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

Lmao. Is this not a "casual script"? The dude wants to try a handful of passwords, not brute force a leaked db.
