PHP - Manual: Random\Engine\Secure
2025-02-27
(PHP 8 >= 8.2.0)
Generates cryptographically secure randomness using the operating system’s CSPRNG.
The randomness generated by this Random\Engine is suitable for all applications, including the generation of long-term secrets, such as encryption keys.
The Random\Engine\Secure engine is the recommended safe default choice, unless the application requires either reproducible sequences or very high performance.
