Workshop: Computer Security

Basic Crypto for Everybody

3 Apr 2014

The internet is broken. Who we call, where we are, what we send each other; all this information is logged and stored for large-scale data analysis. This workshop is about opting out of this social experiment. Specifically we will be looking into preventing browser tracking and securing communication channels and online payments (TOR, GnuPG, OTR, and Bitcoin). Your computer will become (a little more) safe and private again. Get your tickets online, space is limited.

Stefan Hechenberger will show you how to conceal your identity and location from data collection agencies with the help of Tor. You'll also learn how to setup and use secure communication channels to prevent governmental spying with E2EE (end-to-end encryption). This will protect your e-mail and make sure you can instant-message privately and securely. Bring a Notebook with Windows/OSX/Linux. No prior crypto skills required.


Tor provides the foundation for a range of applications that allow organizations and individuals to share information over public networks without compromising their privacy.


End-to-end encryption means communication between two people is encrypted, and can only be read by the person with the right 'key'. This type of communication prevents third parties from being able to read the content of what you're sending. So: the government will know you sent an e-mail, but won't know what was in it.
