Extracting private keys from wallet.dats?

[michaeladair]

Is there any way to extract wallet keys without having to turn off my wallet and change wallet.dats? I'm wondering this because here has to be an easier way if I'm stuck with a ton of wallet.dats, I'm wanting to code a bot to do this for me and put em all in a text file. Any ideas?

pywallet?

If you're using bitcoin-qt (bitcoin core) wallet, you can open Help/Debug and go to the console. Enter

dumpprivkey "bitcoinaddress"

to extract the private key. If you encrypted your wallet, you must enter the wallet passphrase with "walletpassphrase" first.

Private key is shortly after a "keyA" ascii sequence in the file.

They should be useful, especially if you want to code the priv key searcher.

Can this be done in cmd using a language like autoit or something... With the wallet.dats on hand?

not just with the wallet.dat.
 To run this comand you have to run the client on your computer ( bitcoin core )

This requires to change the wallet.dat files each time. OP could just use pywallet.
