Everybody talks about cryptography, but only a few understand what it means. This interactive session will explain the very basics of cryptography and will leave the attendants with more confidence why to use cryptography.

Many talks mentioned cryptography somewhere along the presentation and everybody just nods. But how many people actually know the insights of cryptography? Why some things work and some things don't? During this talk I will explain the difference between encoding and encryption, the most common uses of cryptography, the difference between synchronous and asynchronous encryption, hashes. I will include some history and some future developments like quantum and why we call cryptocoin cryptocoin. In a slow pace, scratching the surface for uninitiated, but the scratches will go deep enough for more initiated to get some more background.
