ICRC - Concepts

Client

A user or bot. Or to be more precise: the program something uses to communicate with the icrc server.

Relay

A relay is like a group chat. Clients that are part of a relay have the key to it. The server proofs if a client has access to a relay by hashing the clients key to that relay and comparing it with a saved hash.

User index

Every relay has their own user index, which has the following columns:

• userid_relay: The id that other users use to identify a user in this relay.
• userid_main: The users "real" id. (The id they use to authenticate.)
• name: The users nickname in this relay.
• public_key: The public key to exchange symmetric encryption keys with that user.
