Peak PHP - Let's Get Random!
Let's get random: Under the hood of PHP 7's CSPRNG NOTE: This talk was written and originally presented by Sammy Kaye Powers (https://twitter.com/SammyK). We'll be sharing with permission. 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, and how the new-goodness CSPRNG functions in PHP 7 work under the hood.
