![]() ![]() If you started bitcoind, you will need to stop it before Bitcoin-QT will start again:Īt some point, you may wish to delete private keys from a wallet.dat file but as of version v0.6.0 of Bitcoin-QT/bitcoind, there is no RPC method available for this purpose. These commands will clear the passphrase and private key from memory if you used the read technique. This will lock your wallet again (so you don't have to wait for timeout) There is currently no command to import a batch of private keys so you will need to wait a minute or two for each key to be imported. If you need to import more keys, just repeat the instructions above. If no errors occurs, the import is a success and Bitcoin-QT users will be able to see the new address in the GUI immediately. (space)bitcoind importprivkey 5yourveryveryveryverylongprivatekeystring" "label-here" rescan=false This process will take from one to two minutes, depending on your CPU performance. Bitcoind will rescan the entire block data to ensure this key has not been used before. (space)bitcoind importprivkey "5yourveryveryveryverylongprivatekeystring" "my-new-key" # "my-new-key" is a label for the key/address pair and is optional Since private keys can be as important as your passphrase, you may want to use the same techniques as above to prevent their being recorded in bash history (bash variable or space before the command): The last command unlocked your wallet temporarily for 120 seconds, during which time you must import your private keys. (space)bitcoind walletpassphrase yourpassphrase 120Īnother alternative is to use a bash variable:īitcoind walletpassphrase "$x" 120 # Do not set the timeout too long or too short. Typing this directly in a bash terminal will leave your wallet passphrase directly in the bash history but there are a couple of techniques you can use to avoid this. The RPC command for unlocking an encrypted wallet is walletpassphrase. If you have an encrypted wallet (recommended), you need to unlock it temporarily before importing private keys. Close Bitcoin-QT and restart it with bitcoin-qt -server.The version of bitcoind MUST be the same as bitcoin-qt!īitcoin-QT does not enable its RPC interface by default. Close bitcoin-qt and start bitcoind -damon in Terminal Emulator.Instead, you need to start the bitcoind server.
