Help with old Wallet Master Key

[DarkDTox]

BTC Hi Guys I have dug out an old bitcoin wallet master key from 2013

I'm not great with the old stuff and it was originally with schildback.wallet. All the GitHub data is there, but need some assisatnce to decrypt it and check it.

BTC Hi Guys I have dug out an old bitcoin wallet master key from 2013

Please first confirm what you have:

1) Master private key as you claim, it starts with "xprv..."
2) A .wallet file.
3) Individual private keys usually beginning with 5, K or L.

If you have "xprv.." I would assume it is a BIP32 wallet. In that case you have two options.

1. Download Electrum and import the key: https://electrum.org/.
2. Save/download this website https://iancoleman.io/bip39/ and then open it in your browser locally (you need to open the index.html file probably). You can input the master private key there (BIP32 Root Key) and derive your addresses. You may need hardened derivation ticked, check addresses of both in case you are unable to locate anything.
In any case if you are genuine about this, do not share any of this information with anyone. If there are any funds on that wallet they can steal them using your key and you won't be able to do anything about it. Are you absolutely sure you had funds on this wallet?

Do a run down on this thread first: [HOW-TO] Export Bitcoin private keys (in WIF) from Bitcoin Android (schildbach)
See if anything in the OP and replies look similar to your "Master Key" and other files as your post suggests that it's encrypted.
Also, that's posted in a dedicated board for Bitcoin Wallet for Android so try to search the board and you may find a thread or two with similar issue that was solved.

If nothing helps, you should describe what you have in detail like providing "not-actual-examples" and the feasibility of decoding it (if you know or at least have an idea of the password).

What do you mean by digging up an old master key? Is it the password/passphrase of the wallet app?

You cited "Schildback.wallet", you are probably referring to the Bitcoin Wallet app (Schildbach Wallet) , in this wallet, the backup is done by exporting a file encrypted by the user password, is this password you are referring to, right?

Also, if you have added a PIN CODE to protect the wallet from unauthorized spending, even if you manage to decrypt the backup file (e.g Bitcoin-Wallet-Backup-2014-11-15-15 28), you need to use Bitcoinj to decipher the wallet file pin to export private keys. There are several related topics about decoding the backup of this wallet

Unfortunately it's difficult to decrypt, it is recommended to install the Bitcoin Wallet application for Android again and try to decrypt there.

I had an old Schildbach wallet backup on my PC that I couldn't figure out how to recover.

I found a thread on Reddit (https://www.reddit.com/r/Bitcoin/comments/1k801iz/comment/n4veq30/?context=3) which detailed a Python script for decrypting it (along with the password that I already knew) which helped me recover my seed phrase and import it into Electrum. I hope this helps you too!

I think it would be much easier if you had a password for your "schildback.wallet" because you could directly import it to the app.
The app still exists on F-Droid; just use the link from this link below.

If you want to decrypt it and extract the private key, Schildbach has a guide you can follow from this link below.
