Welcome to OTRv4!

This is the place where the team keeps notes.

What is OTRv4?

OTRv4 is the version 4 of the OTR protocol. OTR cryptographic protocol that provides encryption for instant messaging conversations.

The conversation around the needs for having a 4th version of OTR started at a meeting had in Valencia, Spain at the IFF (some notes are here). A version of this protocol has already been reviewed as mentioned here.
