Topic: Extracting Private Key (Read 85 times)

Import the private key using gpg on Linux and look at the meta information.

However, if you import the private key into a PGP app, it may contain some helpful information.

Could you please give me an example of such a program for mac os or Linux and how do i use it with my file to get more information about the file.
How do you think, basically, can the file in the format PKCS1 private key (unencrypted) in PEM contain private key BTC.
I've been googling for days and i haven't moved anywhere yet. I read, that servers like BitGo use JS when creating the new wallet and generate files in similar format.
Although, i don't really know much in programming to say that.
Thanks!

I suspect that the wallet is a custodial wallet and that access to your account can be gained using the the RSA private key. I am not that familiar with the different custodial wallets, so I can't tell you which one it is.

However, if you import the private key into a PGP app, it may contain some helpful information.

When I enter the password it says - bad magic number and makes an empty bitcoin-wallet-decrypted-backup file.

If I leave the password field empty and click enter, it doesn’t print and makes an empty bitcoin-wallet-decrypted-backup file.

Thanks, I'll try now.

What's the purpose of using that tool?
It is not a tool to generate or create a wallet read this below if what it is used for.


About the backup wallet that your friend created for you it might be a Schildbach wallet backup there is a tool to decrypt the wallet on their GitHub documentation. Check the link below for the guide

- https://github.com/bitcoin-wallet/bitcoin-wallet/blob/main/wallet/README.recover.md

That website has nothing to do with Bitcoin. Not sure why you are using it at all?

The PGP key will have a public key. The public key can be sent to someone to encrypt a message which only your private key can decrypt.

Yes, I know that, but what do I do with this file? Where do I use it?

Do not share your private key with anyone, else your coins would be stolen.

The private key above is PGP encryption, not bitcoin private key.

Bitcoin private key will start from xprv, yprv or zprv for master private key, while it will start from 5, K or L for child private key.

Brief background: in 2017 my friend created a new BTC wallet for me and made a USB backup copy for me. Sadly I didn't take part in the process of creating the wallet and I don't know on what platform was it created. Currently, I am trying to get access to my funds, but I absolutely don't understand how do I do it with USB backup copy.
To sum up: I have an address for my wallet, password, file called enc without file extension (pem, dat, text, etc.)

I opened this file using password that I used when creating the wallet in the http://bitwiseshiftleft.github.io/sjcl/demo/ service and got this content.

And then I absolutely don't understand what to do with this file.

In this thread  https://bitcointalksearch.org/topic/extracting-privat-key-from-pem-file-5309706 people say that you can extract PRIVATE KEY BTC out of such a file, but I don't understand if this is my case. In other posts I've seen people mention similar file for the BitGo wallet, but there iter":10000,"ks":256 + to recover BitGo wallet you not only need User Key but also ( Backup Key+BitGo Public Key ).
I would be grateful for any help!

P.S - Files in the examples are changed.
