I hope for an email renaissance, as email is the working example of a decentral, securable, interoperable, multi-use communication standard. It is much more useful to people as many realize. > I would also would love GnuPG to get up-to-speed with a number of modern > threat scenarios and use cases that currently are solved (good or bad I > can't say) by Signal or Threema or <preferred-smartphone-chat-app>. > > I don't know if GnuPG is, by design, a tool oriented to other use cases. GnuPG (as I understand it) is designed for asynchronous communication and a key pair holder can stay anonymous. So GnuPG is not really designed for online use (like with webpages and services, where there is TLS and CMS client certificates) and not for streaming or file systems either (because missing regular throughput or random access). The problem with messengers is that they are more inclined towards online usage and they need a central registry. As example as far as I know, perfect forward secrecy only works if there is an online connection to negociate the keys. To allow a pseudo asynchronous use, the double Double Ratchet Algorithm used in some messengers uses prekeys that have to be generated and uploaded so a server. And I guess you can deplete them. There are GnuPG/OpenPGPv4 based solutions with messenger properties, e.g. https://xmpp.org/extensions/xep-0373.html aka OpenPGP for XMPP (though OMEMO is probably more distributed) https://delta.chat/en Best Regards, Bernhard -- https://intevation.de/~bernhard +49 541 33 508 3-3 Intevation GmbH, Osnabrück, DE; Amtsgericht Osnabrück, HRB 18998 Geschäftsführer: Frank Koormann, Bernhard Reiter
