Message definition (Concepts/OpenPGP For Beginners)

As the names suggest: The secret key is to be known to its owner only, and the public key should be known to everyone ideally. With symmetric encryption the problem was to safely share the password with the recipient of a message. With public keys the problem has changed: Now the hard part is to be sure that you are using the correct public key (and not a forged one an attacker tries to trick you into using).

Som navnet antyder kendes den hemmelige nøgle kun af sin ejer, mens den offentlige nøgle ideelt set skulle være kendt af alle. Med symmetrisk kryptering var problemet, hvordan du sikkert delte kodeordet med modtageren af en meddelelse. Med offentlige nøgler er problemet ændret: Nu er den vanskelige del at sikre dig, at du bruger en korrekt offentlig nøgle (og ikke en forfalsket nøgle, som en angriber prøver at narre dig til at bruge).
