Greetings to everyone of you.
Me and my brother used to have BTC on bitcoin core, and we encrypted it.
But last year the device that we used for that specific wallet and also the notes of password were on my room, but the house got caught on fire and unfortunately everything was burnt down.
But last week i opened my hard drive to put my wedding pics on it, ive found the backup of wallet.dat on it, but we have no idea how the password could be.
Is it anyone here that can give help and solve the problem.
Thanks a lot for your time.
Best Regards!

If your wallet was encrypted like passphrase protection, then you can do this below steps..

If it's your wallet.dat file, then you can know some password hints of your own. Let you try with bruteforce method of hashcat(GPU method), BTCrecover(CPU method) and pywallet method.

If you tried and still you encountering with no luck on getting passphrase, Then you can try this method.

You can do this when it is your own wallet. If you are trying to do on some other people wallet.dat files, the it will be considered as stealing. However, Here you going to crack the private key of the encrypted wallet.dat files through reverse engineering core wallet called cracked btc core qt wallet. It can show the private key by typing dumpprivkey BTCaddress in console , even it was encrypted wallet.dat.

You can open your wallet.dat file through text format and press ctrl+F to search box and type name to find the btc address of wallet.dat file. You can dumpprivkey with the shown address in wallet.dat file for getting private key.

First, You should Install the Bitcoin Core wallet -0.18.1 https://bitcoincore.org/bin/bitcoin-core-0.18.1/

Second, Remove the wallet.dat in Bitcoin directory and move your wallet.dat file in bitcoin directory. The installed wallet.dat should be replaced with your wallet.dat that needs to be recovered.

Third, Watch the video to see how to dumpprivkey of your address without walletpassphrase or password to view the private key - https://youtu.be/C_yNMPnnqS0?si=8Ukr9VPA1c-igz3P

Once you get the private key of your encrypted wallet.dat file, then install electrum in your PC. https://electrum.org/#download

Open your electrum wallet -> Create new -> Import private key(last option) -> Paste your private key and click ok to get your wallet view and spendable.
