what can be done with this I know nothing about how this works.
It's encrypted for a reason: So anyone who got his hands on it wont be able to decrypt the private key without the owner's password.
(
it's doing its job)
So even if this is legit, there's nothing you can do about it if you don't have any idea what the password could be.
Bruteforcing it requires a significant part of the password to have a reasonable chance even if it'll take years, unless it's a weak short password (
which less likely to be the case)
Brutefore isn't cheap either, so if you ever want to try;
make sure that you're going for it because you're actually sure about the information that you will give to the bruteforce tool/service.
Not because you feel it'll work or you'll just waste your time and money (
hardware/power) or someone else's.
If someone claimed that he can decrypt it without any hint for an up-front fee, that's a scammer.
