The ID card, the passport, the electronic health card, smart meter gateways and SSL/TLS work because there is an underlying public key infrastructure (PKI). In the workshop “PKI in a nutshell”, we will show the mechanisms, tools, formats and components of a PKI and how they function and work together.

The workshop uses a “bottom-up” approach. With 8 concrete openssl commands a PKI will be built up, concepts and mechanisms of a PKI will be explained based on these commands. The theoretical basics will be explained and knowledge will be imparted by means of practical examples.

The event is aimed at software developers and architects as well as system administrators who work with PKI systems. The whole event will be held in English and is limited to 25 participants.
