In this video I talk about the most popular messengers, their security and respect for privacy. The following will appear in the video: Signal, Wire, Whatsapp, Messenger, Session, Telegram, Skype, Chat, Zoom, Threema and Wickr Me. I have omitted many niche projects due to their low popularity (Tox, Matrix, Briar, Jami, Usecrypt or Cypherdog) - but let me know if I should consider them in the next edition. ;) Chapters: 0:00 Introduction 0:20 Sources of identity 2:11 End-to-end encryption ???? 4:38 Perfect Forward Secrecy 5:42 Business model ???? 8:08 Secure by default 9:09 SIM card cloning 11:47 Cryptographic methods used 13:12 Local data encryption 14:25 Self-destruction of messages 14:47 Openness of messengers 15:58 Audits 17:26 Metadata 17:46 Which messengers do I recommend 20:39 Which messengers do I not trust 21:47 What to do and how to live?
