Esqueça WhatsApp, conheça o Briar! A Evolução dos Aplicativos de Mensagens

Mobile messengers have largely replaced email and SMS for most people. Many
provide more security by default while being easier to use. However, most
existing messaging applications (even WhatsApp) are still not where we need
them to be. This presentation will show the short-comings of the existing
messengers and show how Briar improves the status quo.

Briar is completely Free Software and works peer-to-peer. It is designed to
resist surveillance and censorship by an adversary with capabilities matching
those of the NSA while still being easy to use.
