One of the sessions I liked most on Microsoft Technology Summit 2011 was one delivered by Krzysztof Bińkowski – it was about certificates and PKI in context of Windows Server 2008. I’m not going to describe the session here, but wanted to share the tool that might help better understand the world of cryptography.
To better explain theory provided on his slides, Krzysztof used CrypTool. Let me cite the authors of this tool to give you a basic idea on what CrypTool is:
CrypTool is a free, open-source e-learning application, used worldwide in the implementation and analysis of cryptographic algorithms. It supports both contemporary teaching methods at schools and universities as well as awareness training for employees and civil servants.
