The XMPP foundation has begun standardizing the [OMEMO end-to-end encryption protocol][omemo-xep]. Therefore,
|
||
|
|
I decided it would be a good time to include support for this interesting new protocol on the xmpp.dk server.
|
||
|
|
|
||
|
|
In practice, this means I have installed a new plugin, mod_e2e_policy, which enables support for the three major
|
||
|
|
e2e encryption standards on XMPP nowadays, namely OTR (which you already know quite well), OMEMO and OpenPGP/GPG.
|
||
|
|
|
||
|
|
OMEMO provides several advantages over OTR. Among other things, it supports offline messages, group chats (which means
|
||
|
|
I can also start looking into enabling MUC conferences on the server at some point) and also it does away with
|
||
|
|
user-based fingerprints and instead uses device-based keys. This is especially useful if you're connected on multiple
|
||
|
|
devices simultaneously. As you know, this was problematic with OTR, but with OMEMO you can get end-to-end encryption
|
||
|
|
on all of your devices and hopefully never lose a message.
|
||
