Can anyone help me with the commandline to get a Private key using a locked core wallet with a passphrase and the address?
I am trying to do this with dogecoin core but it gives me error, i have done it fine before but the wallets were not locked with a passphrase.
You simply add "walletpassphrase "your walletpassphrase here" 600 dumpprivkey [your Bitcoin address here]"
Then relock your wallet with "walletlock"
Assuming that you know how to get into the console, this shouldn't be too hard to accomplish.
