TLS version intolerance

Working around bugs in legacy TLS stacks

Slides from a short talk at the Berlin AppSec & Crypto Meetup, a continuation of Hanno Böck’s talk about TLS version intolerance from a month before. He explained how with TLS 1.3 just around the corner there again are growing compatibility concerns about legacy TLS stacks. I covered the latest TLS WG developments around version negotiation for TLS 1.3 and GREASE.
