I need a graphical representation of the elements of asymmetric cryptography (public key). I have not been able to find an established convention in this area and I find it difficult to find myself good candidates for:
- Private key
- Public key
- asymmetrically encrypted content
These are technical concepts, but the target audience understands the distinctions and their explicit processing is integral to the purpose of the target application.
The padlock seems pretty well established for the encrypted content, so some variants might be candidates. But which turn would be sufficiently distinctive and, if possible, suggesting a difference from a usual one?
In the same way, how can I distinguish the two types of keys so as to indicate immediately that they are different and that it is also easy to deduce or at least to know which one is which, provided that you already understand the context.
Particularly grateful for successful uses in nature, but also for good ideas. Concepts must be able to be expressed at moderate sizes.
