Examining DES-based Cipher Suite Support within the TLS Ecosystem

Explore the prevalence and implications of DES-based cipher suite support in the TLS ecosystem through this insightful conference talk. Delve into the background of DES encryption, understand its significance, and examine where it's still being used. Learn about passive analysis techniques, TLS connections, and DES ciphers. Discover findings from a comprehensive census using automated tools, revealing DES support across top websites and countries. Investigate Triple DES support and specific case studies, such as Canada's DES usage. Analyze the limitations of the study and key diagrams illustrating the ecosystem. Understand the reasons behind continued DES support and learn how to remove it from systems. Examine OpenSSL and browser support for DES, identifying key players still utilizing this outdated encryption method. Conclude with a summary of findings and engage in a Q&A session, with references to the accompanying research paper.
