I have a password-protected RAR archive I'm interested in opening, and I received nonsense instructions on how to get the password (all legal, as far as I can trace).

I cross-referred four languages of the instructions; it didn't help. Do any of you know a way where I can just get through this?

Sorry to say, I'm not sure you can do anything short of trying to brute-force the password (key). If it's simple, it might not take long. If it's complex, you're better off saving your time.

And I don't have any recommendations, software-wise. I've never been in that situation. Good luck.

A quick google search indicated that password-protected RAR archives are actually encrypted using a hash of the password, and so the only way to break them are brute force attacks (either by checking all possible passwords, or a dictionary of likely passwords). There are some utilities you can download which will perform the brute force attack for you, but I can't vouch for their usefulness or safety. You may be better off trying to obtain the password or contents of the RAR some other way.
