+  <code class="sig">Crypto.random_bytes(n) -&gt; string</code>
+  <div class="desc"><p>Draws <code>n</code> bytes from the operating system's cryptographically-secure random number generator and returns them as a <code>2n</code>-character lowercase hex string. Use it for unguessable tokens, nonces, and session secrets — anything whose whole value is that an attacker cannot predict it. The result is hex rather than raw bytes for the same reason digests are: a <code>str</code> is null-terminated and raw random bytes can contain a zero byte, so hex is the form you can safely store and compare.</p><p>This is deliberately **non-deterministic** — it must never seed the lockstep simulation RNG (<a href="ns-Random"><code>Random</code></a>). Two calls return different values. On a platform without an OS CSPRNG (for example a bare wasm target) the draw degrades to zeroes rather than faulting; treat a real CSPRNG there as a platform-layer responsibility.</p></div>
