Message definition (Concepts/OpenPGP For Beginners)

The encryption of data can be kind of reversed: Instead of creating data which only one key can understand you can create data which everyone can understand but which only one key can have created. This impossibility to create the same data without access to the respective secret key makes this data a signature. Once again: Don't ask for how this is possible unless you really like math.

Kryptering af data kan vendes om på en måde: I stedet for at lave data, som kun en nøgle kan forstå kan du lave data som alle kan forstå, men som kun kan være lavet med én nøgle. Umuligheden af at kunne oprette de samme data uden adgang til den rette hemmelige nøgle gør disse data til en digital signatur. Igen: Spørg ikke hvordan dette kan lade sig gøre med mindre du virkelig holder af matematik.
