The Random\Engine\Secure class

    (PHP 8 >= 8.2.0)

    Introduction

    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.
