Have an old problem from 2012/2013 going on. I have the passphrase and wrote it down but never was able to send coins, and they still sit there.
I should have got private key first with dumpprivkey, but didn't know what I was doing. What I did do was backed up wallet and saved to thumb drives.
What I get is red error screen Linux, like file type not supported (Archive Manager?). Years ago, I remember seeing the white screen and looked "encrypted" but I could make out like litcoin info in there (related to what I think address, etc), but I haven't seen that.
So the problem originated on an old laptop. I have since moved to a new PC. I have the files saved best I can, have the passphrase.
So how could I use the passphrase on new computer with new dowload of Litecoin Core? I don't think this will work and has proven not to work so far.
Since I encrypted the wallet before I got the private key, what is the solution now?
I haven't given up, just given it some time. I was hoping Electrum would work with the passphrase thing, but their seed is 12, mine was less (words). I've tried with " " and ' ' and all one word. The new computer won't let me crack it and I don't think it would even if I got it right. Can I get some clues?
