DESCRIPTION:Over the years\, Delta Chat has matured to be an easy-to-use\, 
 secure\,\nand even fast decentralized FOSS messenger app for all platforms
 .\nIn this talk we discuss two key security architectures:   \n\n- Autocry
 pt and SecureJoin key distribution protocols for achieving\n  automatic en
 d-to-end encrypted messaging safe against MITM attacks\, and\n\n- the open
 -signup Chatmail server network which successfully uses strict\n  cryptogr
 aphic interoperability contraints (DKIM\, OpenPGP\, TLS) \n  instead of IP
 -reputation and spam classification methods.\n\nWe also highlight the six 
 independent security audits and analysis conducted so far.
