Please add a OTR feature to mattermost !!!

Please add a OTR feature to mattermost. From my point of view, this is a must have feature...especially if you would like to replace an existing jabber service.

This is something we're investigating, and currently blocking us:

Some private chats should by default be OTR so that not even DB admins can read them, for example all chats between specific people.

Having no search available for such private messages is understandable and OK for such private messages.

There are two libraries that have been created based on Axolotl

One by Wire.com https://github.com/wireapp/proteus
And another from SilentCircle https://github.com/cukupupas/libsalamander

Allows encrypted group chat, forward secrecy, authentication etc

There is also OMEMO, an extension to XMPP which improves on OTR encryption by allowing group chat encryption and forward secrecy.

Based on the same Axolotl protocol as Signal.

I'd suggest using Signal's improved OTR encryption protocol that amongst other things allowed encrypted *group* chats.

They've already implemented their protocol on WhatsApp so asking them directly may also be useful to help implement it.
