The Random\Engine interface
Random\Engine
&reftitle.intro;
A Random\Engine provides a low-level source of randomness by
returning random bytes that are consumed by high-level APIs to perform their operations.
The Random\Engine interface allows swapping out the algorithm
used to generate randomness, because each algorithm makes different tradeoffs to fit
specific use-cases. Some algorithms are very fast, but generate lower-quality randomness,
whereas other algorithms are slower, but generate better randomness, up to
cryptographically secure randomness as provided by the Random\Engine\Secure
engine.
PHP provides several Random\Engines out of the box to accomodate
different use-cases. The Random\Engine\Secure engine that is
backed by a CSPRNG is the recommended safe default choice, unless
the application requires either reproducible sequences or very high performance.
