I have an encrypted private key and I know the passphrase, plus I have a salt. Is It possible to get the private key? It is from an old Bitcoin core wallet. Thanks for any help.
I do not understand. What do you have? Wallet file? Or private key exported?
Usually when you export from Bitcoin Core (dumpprivkey) it exports key to WIF format, which is not encrypted. (starting with 5.... 51 characters or starting with K or L... 52 characters).
I have a wallet.dat file that I recovered from a hard drive using recovery software. I ran pywallet through it, and all it showed was one encrypted private key and a salt and I knew the correct passphrase, which I used . I have also used pywallet on the full 400G drive, and all those recovered files found by that method have included address, public key, master key etc. The lone encrypted private key is different to any of the ones found by doing the full drive search.
