ARPA2 Identity Coding
The following pages detail a few encoding tricks in the local-part of an ARPA2 Identity, so in the part that usually contains the username.
Note: Local parts can be locally defined. But with the aim of allowing the same or similar ARPA2 Identities for various protocols, we are scattering the knowledge over protocols. At least in the interest of security does it seem to be a good idea to standardise them voluntarily.
