<div class="desc"><p>Identical to <a href="crypto-random_bytes"><code>Crypto.random_bytes</code></a>: draws <code>n</code> bytes from the OS CSPRNG and returns them as a <code>2n</code>-character lowercase hex string. The two names are interchangeable; <code>random_hex</code> exists so call sites can be explicit that the return value is already hex text (not raw bytes) when that reads more clearly. The same determinism caveat applies — the result is unpredictable by design and must stay out of the reproducible simulation RNG.</p></div>
