This document discusses SSL/TLS and its implementation on websites in Barcelona. It provides an overview of TLS including its core components like authentication, key exchange, and encryption. It then analyzes the TLS support of popular Barcelona-based websites, finding that while some offer partial TLS, only Tuenti fully implements TLS for login and browsing. Resources for further learning about TLS, HTTP/2, and performance are also referenced.
