Signal depends on Google Play Services since it uses Google Cloud Messaging to talk to Open Whisper System's central server (which you need to personally trust). It's de facto lead developer, Moxie Marlinspike, is bemusingly hostile to any attempt to remove this unwanted dependency, closing a pull request for WebSockets support for little or no justification, attacking those who are pushing for this, and threatening the LibreSignal project with a ban from Open Whisper System's service with the additional mention of legal proceedings. I can't personally recommend Signal to anyone because I can't use it. No matter to me because i've got no friends haha XD>>1841
There's a reason there are so many secure messaging efforts, because somebody thinks "hey that system is like kicking dead whales down the beach" and instead of trying to change it or fix it they go and roll their own. Sometimes, though, this is required since the architecture and approach is different, say between distribution using DHT (Tox) and centralisation with a third party server you need to trust (Signal).>>1853>djb's NaCl is the gold standard
libsodium is the new hotness with API compatibility with NaCl as well as an improved build system and portability. https://github.com/jedisct1/libsodium>>1916
Quote from the Antox developer on IRC (paraphrasing slightly): "Antox is a really well designed app. I don't use it though I like battery life LOL"
This is Tox's biggest failure in my opinion; you can't have a joined up identity on your phone and your laptop, for example, and the distributed model is just a plain bad idea for running on a mobile phone, since you need to be listening and jostling for peers all the time, which has it's impact on battery life and data usage.>>1918
Tox had a major soykafstorm when one of the leaders involved in the project nicked the Tox Foundation charity's dosh and used it to fund his own little jolly. Their split amounted to a new website being registered.
