Opening encrypted wallet.dat file

[ararara]

Hi all,

I have an old wallet.dat file which is encrypted (2013), which I have some guesses to what the password is.
The thing is, I have no idea how to try the password on the wallet.dat file to decrypt it.

I used Electrum, which says it can't read the file. I used blockchain.info's import wallet functionality, but later read that it's not supported anymore.

How am I supposed to open my encrypted wallet.dat file and enter a password to unlock my old Bitcoin?

When you install bitcoin core it'll generate a new wallet.dat
Swap it with the encrypted one you have.
Then go to help -> debug -> console

Code:

walletpassphrase <passphrase> <timeout>

Eg

Code:

 walletpassphrase passphrase 600

Code:

walletpassphrase <passphrase> <timeout>

Eg

Code:

 walletpassphrase passphrase 600

Thanks for your answer, I have bitcoin core installed but I don't know where to put the wallet.dat file so QT recognizes which wallet to try the passphrase on... If you understand ^^

It's located in C:\Users\YourUserName\Appdata\Roaming\BitCoin (If you're using windows Vista and above

I do not seem to have any bitcoin map in my Roaming directory....

You probably installed it to a different directory. Is your node fully in sync? If it is, the directory you are searching for should be around 150-200gb. If you still can't find it, just uninstall core, reinstall it and remember where you chose to install the blockchain this time.

Hold the windows button and the R button
Then paste this

Code:

%APPDATA%\Bitcoin

then press enter.
It should open the bitcoin data directory

I found the location and replaced the file, now when I open bitcoin QT, it shows that I can encrypt my wallet again. Seems like I did not encrypt it... Where can I find my public address/private address of the wallet?

Go to File>Receiving Address. This will display all of the addresses that were generated by you to receive payments.

If you want to get every addresses in the wallet, go to Help>Debug Console>Console and type:

Code:

listaddressgroupings

To extract the private key for each of your public address from Bitcoin-Qt, type below command under the console tab.

Code:

dumpprivkey BitcoinPublicAddress

In place of BitcoinPublicAddress you have to mention your Bitcoin public key address.

dumpprivkey BitcoinPublicAddress

In place of BitcoinPublicAddress you have to mention your Bitcoin public key address.

When dumping multiple private keys this command might be better:

Code:

dumpwallet C:\path\to\dump.txt

This command does dump all private keys into a .txt file.
But note that the private keys will be saved in this .txt file in plain text. Never execute this command on an (eventually) compromised computer.
