Successfully identified passphrase but can't decrypt keys

[dkori]

I was able to successfully identify the correct passphrase for a very old wallet.dat file (last used December 2013) using the btcrecover tool (thanks so much! I'll definitely donate once I have access to the funds again).

However, when I try to use the passphrase to dump the decrypted wallet using pywallet, the program crashes. I'm able to dump the wallet with encrypted public keys using pywallet when I don't enter a passphrase.

I'd like to avoid installing Bitcoin Core and downloading the entire block chain, and I also don't know if the wallet is even compatible since it's so old. Is there a way for me to use btcrecover to dump the decrypted private keys now that I have the right passphrase? Thanks again!!

I think you can export the private keys from Bitcoin Qt using commands in the debug window even if offline or if the blockchain has not yet synchronized. The instructions at these two links seem to be the same. I think you can do these steps without it being synchronized.

This might help too.

If you export your private keys without syncing the blockchain, make sure you get your change addresses. I did that once and left some in a change address that I didn’t realize existed.
