Enter ID and full name
ID and name will be visible to future communication partners using my public key.
Key_ID: I change the place holder "ID?" to my acronym.
It is recommendable to leave the appendix "-33a0" unchanged.
The appendix "-33a0" is a helper for individualisation. It helps avoiding accidental collisions with other IDs on your and your partners systems.
If my name is John Smith, I could e.g. change the ID from "ID?-33a0" to "jsmith-33a0".
