I have been developing a web app and used many autogenerated ETH addresses. I stored all of them into one folder in the next format:
/storage 123456789/ mainnet.eth.privateKey: "0xdeadbeefdeadbeef...deadbeef" mainnet.btc.privateKey "Kw123123123...AbCDeF" .../
Where the dir is always some generated number, and it stores raw private keys (WIF for bitcoin).
During development, I have used a few addresses to store real ETH. But unfortunately, I haven't keep track of the IDs for those addresses. And one of this addresses now has some amount of ETH which would be nice to get back.
However, the amount of directories is overwhelming (over 100 at least), because they've been autogenerating for each launch if not provided.
Still, I am pretty sure it sits on one of the machines I have been developing on. Of course, Now I can go through them manually, checking one by one, but that would be too long, in the end, there is no millions locked.
So the question is if there is any utility that automatically searches a private key and matches address to given address or a tool that just checks a balance for any string that looks like private key?
Maybe there exists a command line snippet to check balance for found private-keys-alike string?
