Private messaging

A user may start a private messaging session with another user by clicking their name in the user list of a channel. A session lasts until either user disconnects.

Messages in a private messaging sessions are end-to-end encrypted, and participants are deniably authenticated toward each other. This means that the server cannot read messages sent between participants and that participants can prove to each other who they are (authentication) without leaving a cryptographic trail (deniability). See the Deniable authentication page in the appendix for more information.
