[App Request] More secure messaging using Retroshare

Another secure communication solution is Retroshare (open source, Qt based). There is a linux/windows/apple version and there seems to be a qt mobile version. And there is a retromessage mobile version. Retroshare security is based on pgp keys. http://retroshare.sourceforge.net/downloads.html http://retromessenger.sourceforge.net/ Anyone care to explore this on Jolla?
