CBR: Facebook launches open source group chat encryption tool

CBR: Facebook launches open source group chat encryption tool . “Facebook has made a new tool available via GitHub that allows users to apply encryption to their social media group chats. Named the Asynchronous Ratcheting Tree, the open source tool is designed to enhance the security of Facebook Messenger, WhatsApp and the Signal App among others. In the event of a security breach, the tool would work to re-establish security, instead of simply leaving the entry point open for a hacker to return to in future.”
