I don't think you will be able to use that site, as there are some other background things happening that I don't think that website supports, but assuming you can decrypt the master key, then it should theoretically be possible to then decrypt individual private keys.
As for decrypting the master key, I found this project which claims to be able to extract the encrypted master key, salt, IV etc from a wallet.dat: https://github.com/brichard19/core-decrypt
There is also an OpenCL based project included (and a precompiled .exe
) that claims to be able to test the master key decryption using a password dictionary. The idea being that you can identify what the wallet passphrase is... it doesn't decrypt individual keys, and it doesn't show the decrypted master key etc. It just seems to test the "encrypted master key" decryption using passwords you pass in.
If this information regarding wallet.dat encryption is still valid: https://en.bitcoin.it/wiki/Wallet_encryption
Then it looks like you would need to start playing with your wallet passphrase, SHA512 and OpenSSL "EVP_BytesToKey" functionality (along with the extracted IV, Salt, iteration count etc as extracted by the python script) to derive the "key" needed to decrypt the "encrypted master key"...
and then once you have the "unencrypted master key", you should be able to decrypt the individual private keys.
The passphrase is no problem as I already know it. I wonder if the salt and iteration are viewable within the wallet file? How do these various scripts find them?As for decrypting the master key, I found this project which claims to be able to extract the encrypted master key, salt, IV etc from a wallet.dat: https://github.com/brichard19/core-decrypt
