In my home directory there is a file called -. Seeing inside it was hard, but I finally managed to do it.
At the top was this:
-----BEGIN PGP PUBLIC KEY BLOCK-----
followed by a bunch of characters. Then at the end was
-----END PGP PUBLIC KEY BLOCK-----
I don't have pgp or gpgp installed. And another strange thing is that the date of the file is from last year, way before I installed this OS!
What could be happening here!?
