I have found an old wallet.dat file when clearing out my old HDD’s. It looks like wallet backup files from 2013-2014 with the format LTC28112013.
I installed the latest litecoin wallet on my windows machine and added the file and renamed it wallet.dat and the client updated including all the coins in the wallet. Problem is the wallet is encrypted, its asking for the wallet passphrase when i try to transfer the contents of the wallet. Is there anyway around this?
