This video was recorded at Code BEAM V 2020 - codesync.global/conferences/code-beam-sto/ TLS the OTP way | Ingela Anderton Andin - Software Engineer ABSTRACT TLS-1.3 is a major upgrade of the TLS-1.2 protocol. A lot of legacy is thrown out and new mechanisms will replace old flawed ones. Most of the TLS handshake will be encrypted as opposed to earlier when most of the first handshake was in plain text and encryption started first when sending the final handshake confirmation message. TLS-1.3 also puts new requirements on TLS-1.2 to pave the way for migration. Supervisors, generic behaviours, logger, gb_trees, ets, queue models, maps, try catch, binaries, records how are they used and why. OBJECTIVES Spread good design principles with Erlang/OTP and security knowledge by sharing design decisions, trade-offs and optimisations that we have done implementing TLS (all versions from SSL 3.0 to TLS 1.3 but with the biggest focus on TLS-1.3) in Erlang. TARGET AUDIENCE People interested in using Erlang/OTP to its full potential, and also people interested in TLS-1.3 in particular and security in general. • Follow us on social: Twitter: https://twitter.com/CodeBEAMio LinkedIn: https://www.linkedin.com/company/27159258 • Looking for a unique learning experience?
