Do this first before you do all suggestion above.
Make sure to make an original copy of your wallet.dat because I heard someone here experience corrupted wallet.dat file after they imported it to the latest version of Bitcoin core wallet.
So for your wallet safety make sure you have the original wallet.dat and only use the copy file to import it into the Bitcoin core folder.

You can decrypt your wallet file, extract the data, and export it to any wallet. the problem is you will need to be connected to the Internet to check your balance.
being offline does not mean that you are safe, you need airggapped system which means that your device has never been and will never connect to the Internet to be safe.

Because you want to do this offline, it might be difficult to identify exactly which addresses you need to dump the private keys for... so you might need to use the dumpwallet command to dump all the private keys from your wallet.dat instead of using dumpprivkey:
The dump_filename can include the full path if you want.
NOTE: if you're using Windows 10... it can sometimes be a bit "fussy" about letting you output the dump file onto C: drive due to various folder permissions etc.
So, in that instance, make sure you either create a temp folder that you can write permissions to, or that you specify the full path to a folder that you have write permissions for.
Code:
dumpwallet [dump_filename]

It was from Bitcoin wallet. I have a feeling the copy of it might have been stolen and someone could have changed the password as my email back then got hacked and i didnt bother much afterward as someone did change the password as i had written jn the saved email.
Was it specifically Bitcoin Core? Do you have the address of your wallet that has funds? If you do you can check it on a block explorer and see it yourself if you got robbed.I just want help how can i open it offline or will it open using my old password without connecting it to the network.
You can open it offline and get your private keys to import them to electrum. By stop syncing, or turning off your internet connection, you can click Help --> Debug Window --> Console.That would work if you enter it on console:
Code:
dumpprivkey [ADDRESS_HERE]
You may also need to enter this before the above:
Code:
walletpassphrase "your password" 600
You don't need to be connected to the network to run Bitcoin Core and open your wallet
Hi i have a walet file saved in from 2014. It was from Bitcoin wallet. I have a feeling the copy of it might have been stolen and someone could have changed the password as my email back then got hacked and i didnt bother much afterward as someone did change the password as i had written jn the saved email. But suddenly going through my old cds i came accross my wallet.dat file. I still remember the password . I just want help how can i open it offline or will it open using my old password without connecting it to the network. I am hoping to take my private key out and usebit in electrum to retrive my old coins.Please help. Cheers. Jap
