Learn you some ‘ssl’ for much security!
Talk in three words: TLS, security, troubleshooting
Erlang/OTP’s built-in ‘ssl’ application forms the basis of many client and server packages. Unfortunately it has quite a few quirks, potentially leading to weak security. This talk highlights the most important client and server settings for ‘ssl’ sockets, how the defaults have evolved across OTP versions, and how popular libraries build on them. Topics include cipher suite selection, server hostname verification, known certificate issues (wildcard SAN, cross-signed CA), revocation checks, ECDSA servers, and more.
Learn to apply secure TLS configurations to clients and servers, either directly with the OTP ‘ssl’ application or through the many libraries that rely on it: Ranch, Cowboy, Plug, Phoenix, httpc, Hackney, HTTPoison, etc.
Anyone building applications that include TLS client or server functionality, directly or through packages, which means just about anyone developing on the BEAM.
