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?
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 ^^
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?
