Alice's TLS Dissector


Mitchell Anderson, James Brink, Oliver Clay, Daniel Chung, and Walt Li


A pedagogical tool to demonstrate the details of HTTPS/TLS protocol in action. Given a URL to browse, the tool can capture the transmitted encrypted packets while browsing the website, use the session key to decrypt the packets, and display the information along with the protocol details (e.g., TLS handshake, SSL certificate verification) on a user interface. The user interface allows users to interactively examine specific details of the connection, such as the TCP handshake, encryption algorithm, and symmetric key exchange.
