On the command line, use the importprivkey command.
EDIT:
Using this utility? or the bitcoind utility? bitcoind --help doesn't show any options for importing a private key.I'm not 100% prepared to use a 3rd party utility unless/until someone confirms it works with the latest official bitcoind client and an unencrypted wallet.
In the standard client. Don't use
--help, just use
help.
--help means you are asking about startup parameters.
help means that you are asking about RPC calls / daemon commands.
It really is just
bitcoind importprivkey
but you may need to play with quotes and escapes, depending on your system. The WIF key is the one labelled Privkey: in vanitygen's output, it starts with a 5.
Thanks for the response/clarification.
I'm on Win7 64, but "bitcoind help" gives me:
C:\Program Files (x86)\Bitcoin\daemon>bitcoind help
error: You must set rpcpassword= in the configuration file:
C:\PATHTOMYBITCOIND_INSTALL\bitcoin.conf
If the file does not exist, create it with owner-readable-only file permissions.So I went and created it - and it complains the server isn't running. Do I need to be running my own bitcoind instance Instead of / in addition to the -qt GUI??
"Bitcoin-qt.exe help" = does nothing other than start the windows gui.
"bitcoind-qt.exe --help" gives pops up a window full of options that you can't resize and that scrolls off the bottom of my screen (1680x1050).
Ideally I have 4 different Vanity addresses, and I'd like to import/setup a separate wallet for each one. - One for personal use, one for Dev, one for a friend, and one for the office.
If I'm running the bitcoind server - am I able to specify which wallet to use on startup or can I do that dynamically?
Sorry if this belongs over in the N00b section.
