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

Quote

dumpprivkey "bitcoinaddress"

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

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

Here is some info how to call the bitcoind API from various languages:

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

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

Private key is shortly after a "keyA" ascii sequence in the file.
Some technical details are here: https://bitcointalk.org/index.php?topic=22697.0;topicseen
They should be useful, especially if you want to code the priv key searcher.

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?
