My boss recently implemented a new security system related to PGP/GPG.
The whole idea behind this is to sign files so that people know from who they came. They don't require us to encrypt them, just verify their authenticity.
The problem is that wrapping my head around such new and complicated concepts is getting harder and harder. We're using GPA Kleopatra.
So what I want to know:
Say I want to send a person a file, I don't know that person, it could be anybody, it doesn't have to be encrypted, and I want him to know it came from me, is there anyway for me to do that?
Again, no encryption, just authenticity verification.
You don't have to explain it to me step by step, a tutorial on some site will do. But keep it simple and straight forward.
