25 Years of SSL - Secure(ish) Sockets Layer

slides:none on file

Timeline from 1994 to today traces concrete breakages and fixes: SSLv1 fails in initial demo, SSLv2 is broken in months, SSLv3 survives until POODLE (2014/2015), TLS 1.0 is essentially a renamed 3.1 in 1999, TLS 1.1 sees almost no uptake, while TLS 1.2 adoption via performance (session resumption) rockets usage; TLS 1.3 appears in 2018 with faster handshakes. Data sources (Google transparency, Mozilla, crawler.ninja, top‑1M scans) show rapid HTTPS growth but a worrying plateau. Browsers remove green padlocks and add red “not secure” warnings; LetsEncrypt and Comodo enable both legit and phishing sites; Kazakhstan attempts TLS interception via forced root certs.
