Building a tool that will allow even the most non-savvy user to extract wallets from drives, hard drives, flash drives, cd's etc.  It is read-only, air-gapped and bootable.  Basically, it is an SSD that automatically scans storage media regardless of it has been reformatted or wiped (but not zero'd).  It boots, and once executed scans drives that are plugged into it and extracts what have been identified as wallet.dat files or homologates thereof.

The app will test against various versions of Bitcoin core to cover all possible iterations of the original Bitcoin Wallet.  The tools to brute force a password will also be loadable in the application.  You pay no one for a service, or pay a commission percentage of your wallet balance, you own it, it is  your tool.

What's fair $100?
