Join us for this Wednesday evening with Bernhard Esslinger to find out why crypto is good but its use is botched and how to understand cryptography and attacks, and how to react.

We'll discuss some of the typical security intrusions and why even
cryptography did not prevent companies losing passwords, customer data, secrets, and reputation. Recommendations are given for developers and managers how to implement and apply cryptography better. Then, cryptography can really fulfill its designated purpose to prevent breaches and data-loss.

However, not only the companies suffer, but also everybody in his/her daily life. For these normal people and for learners, we also have some insights, what they should be aware of and where they rely on others. For instance, even good user passwords don't help if they are stored at web servers with a weak hashing scheme. Even encryption doesn't help if a hard disk's firmware has flaws or if the malware is already delivered within the chip.

This talk is accompanied with demos of CrypTool, the world's most widespread, free e-learning programs about cryptography and cryptanalysis. For example, CrypTool can show the serious difference of resistance between a scenario where the primes for the RSA keys are generated always randomly, and a scenario where single primes are "shared".

Bernhard was head of development for the security components in the SAP R/3 system, then SAP's CISO. After heading IT security at Deutsche Bank, he is self-employed and professor at the University of Siegen. He is head of the open-source project CrypTool which has around 100 volunteers. The downloads of the offline e-learning programs come from all over the world.
