The efforts of the open source community, and especially Scott Arciszewski from Paragon Initiative Enterprises, have resulted into a welcome increase in security for PHP applications, changes that are coming to big projects like WordPress, Laravel, and Symfony.
Starting with WordPress 4.4, Laravel 5.2 and Symfony 2.8, these projects will feature built-in support for CSPRNG (Cryptographically Secure PseudoRandom Number Generator).
CSPRNG is a random number generation algorithm specifically designed for usage in cryptography. Security experts recommend CSPRNG algorithms for generating salt hashes, keys, nonces, and data padding. This is because CSPRNG generates true random numbers with a high entropy (randomness), meaning they are harder to crack in brute-force attacks.
