Title: Associating previous transaction IDs with new wallet / signature-based recovery Post by: mattmill30 on January 29, 2018, 01:50:33 AM I am new to the world of cryptocurrencies, so appologies if this is a noob question.
I setup the core clients for Bitcoin, Litecoin and zcash, but hadn't recieved any transactions. Since then I've replaced my computer and don't have access to the wallets anymore, but I've also now been sent transactions to the public keys. Because I know the public transaction keys, but I don't have the private keys, is it possible to regenerate the private keys? If it is possible, how would I then add the public and private keys to a new wallet? Alternatively I can get access to the previous harddrive, but it has been formatted. Is there a signature-based deep scanner available to detect wallet files?

Knowing the transaction IDs doesn’t change that, as TXIDs are intended to be public anyway.
As for salvaging files from a formatted drive, that’s often trivial and there are ‘unformat’ tools available. Things become more complicated if new files have been written to the drive. If there are large amounts of money at stake, consider sending the drive off to a data recovery expert. There’s information available e.g. at https://www.krollontrack.co.uk. Unfortunately I don’t know if there are any specific tools available to find wallet files.

Pretty nicely explained there is no such tool until now which can specifically find out the wallet based files. Moreover there is no way until you remember the private key to add the seed into the new wallet. Public key is useless when it comes to accessing your seed.

Moreover the second one might not have a free version.

Is there a signature-based deep scanner available to detect wallet files? You *might* be able to use Pywallet to scan the formatted drive looking for wallets and or keys. It has a --recover mode that scans the drive. Might take a while depending on drive size.It works with Bitcoin... And I believe you can use the --otherversion parameter to make it look for litecoin... Not sure if it works for zcash ???
