                 When it comes to writing code, there’s nothing we take more serious than authentication and security. Modern single page applications bring along new challenges. By using solutions like the OpenID Connect protocol and JSON Web Tokens we can improve the user experience when authenticating with your apps, providing a seamless authentication process.
             </div><div class="abstract">
                 In this talk I will try to explain in depth, the way JSON Web Tokens work and can be used to secure your single page apps. I will explain the difference between using opaque tokens and JWTs. The talks will also give an overview of a modern authentication flow and a step by step breakdown of how it works exactly. No specific previous knowledge is required, but it helps the audience has some experience with authenticating users.

                 Voice recognition technology is revolutionising the way we interact with machines, but the currently available systems are expensive and proprietary. Common Voice is a massive global database of donated voices that lets anyone quickly and easily train voice-enabled apps in potentially every language. And offer developers and technologists multilingual datasets to train machine-learning models which enable them to build a wave of innovative products and services.

                 The CrypTech Hardware Security Module (HSM) Project is an international project developing an open-source hardware cryptographic engine design that meets the needs of high assurance Internet infrastructure systems. Until today, HSMs used for CA certificate signing, DNSSEC and Tor, for example, were highly expensive, proprietary tamper protected black boxes. CrypTech is changing that, making HSMs open and available to everyone.
