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

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.
