Through the graphical interface (GUI)

  1. In Windows you should probably just double-click the .exe\.jar file, and it will launch (if you have Java installed, the GUI will not work without it)
  2. In order to open the Bitcoin wallet file: choose “load wallet” and select your wallet. Then the program will ask for a password (if your wallet file\was encrypted). After entering your password, the main menu will display all public and private keys.

Through the command line (CLI)

On systems that have a command line interface (it also works on Windows, it’s a little harder to find there, they really hate their own users), you can also run it by running the following command

java -jar wallet-key-tool.jar

This will open a GUI window that you can interact with, information and error messages will be printed to stderr. If you want to increase the log level, run it like this:

java -Dorg.slf4j.simpleLogger.defaultLogLevel=TRACE -jar wallet-key-tool.jar

Note: the -D option must go before the -jar option, it is passed directly to java. The allowed log levels are ERROR, WARN, INFO, DEBUG, TRACE, the default is INFO, if you want to see stack traces use TRACE.

If you just want to dump the contents of the wallet to the console without interacting with the GUI, you can give it a filename; if you do that, it won’t try to open the GUI, it will just dump the wallet contents. to the standard output and output. Note that the dump format is still subject to change, keep that in mind when writing a parser for it.

java -jar wallet-key-tool.jar <filename>

The program will ask for a password in case the file is encrypted. If you want to avoid the password prompt, you can specify the password with key -password = “my passphrase” (you need quotes if it contains spaces). Example of a session in the console (I did not enter the passphrase, I just pressed Enter, so no private keys were decrypted):

java -jar build/libs/wallet-key-tool.jar /home/bernd/Schotter/Schotter.wallet
[main] INFO org.multibit.store.MultiBitWalletProtobufSerializer - Loading wallet extension org.multibit.walletProtect.2
Wallet is encrypted. Enter passphrase:
no passphrase entered, will skip decryption
