what do you mean exactly?
dumpprivkey only tells you the private key, doesn't delete it from your wallet, AFAIK.

well over a year ago, i used Armory to move my signature privkey from Qt into Armory.  i don't remember the exact sequence of commands i used to accomplish this but nonetheless i find only my pubkey remaining in Qt.

are there any remnants of the privkey in Qt or am i stuck?

Everything should be there.

To export a private key from your Satoshi bitcoin-qt client:

    1- launch your bitcoin client as usual and wait for it to load the blockchain and start up
    2- click on 'help' in the menu bar (top right)
    3- click on 'debug window'
    4- select the 'console' tab
    5- type: walletpassphrase "your walletpassphrase here" 600
    6- type: dumpprivkey [your public key here]
    7- this will return the private key, you can copy it now; ensure you clear your clipboard/history afterwards
    8- type: walletlock

Skip steps 5 and 8 in case your wallet is not encrypted.

sorry, already tried that:  Private key for address * not known (code -4)

[cypherdoc]

Make a wallet backup and then run Bitcoin-Qt with -salvagewallet command. If nothing happens try -rescan to check if wallet recognizes
transactions associated with address in question.

can you be a little more specific about the command lines involved and from what folder?

Are you sure you're trying the correct pubkey? Is the address you're trying to get the privkey from really yours? Didn't you grab it from the Address Book instead of from the Receive tab or something?

wait, in that series of instructions, was i supposed to insert the pubkey or the address?  if it is the latter, that is what i did.

and yes, this was my vanitygen address that i originally imported into this wallet but then subsequently exported to Armory.

If this definitely doesn't work you could try pywallet

You need to run Bitcoin-Qt with commands added, e.g. bitcoin-qt.exe -salvagewallet and then eventualy bitcoin-qt.exe -rescan

and on a mac and from which directory?

how would i do that?  never used it before.

On Linux it's really easy, it's a bit more complicated on Windows but still fairly simple.
Take a look at pywallet.tk and tell me if something seems strange/difficult.

As it's written in the link I just gave you (), the instructions for Mac is in the README.
I never checked myself as I don't have a Mac, they come from an user.

can i simply move a copy of the wallet.dat over to a linux computer and then use pywallet to extract private keys?

[jackjack]
