Randomness is really important in many cryptographic contexts. Unfortunately true randomness is a non-trivial achievement for computers. In fact, using weak sources of randomness can leave your application open to myriad vulnerabilities. Enter: a good cryptographically secure pseudorandom number generator (CSPRNG). We'll discuss the importance of using good sources of randomness, the CSPRNG options we had in PHP 5.x, and how the new-goodness CSPRNG functions in PHP 7 work under the hood.

Highly entertaining talk, speaker and slides. Best of the speakers actually -- it was clear he either practiced or has given this talk before. The content that would at first glance seem too nerd-core and boring was made exciting and interesting. I had no idea that random numbers were so challenging to create! /dev/urandom FTW.

Also, who's down with entropy?! Yeah, you know me!

Engaging, energetic, and effective speaker with great contents. Randomness rethought.
