Secure random tokens, drawn from the operating system’s own entropy.
Released v1.0.0 · 2026-09-28use "stdlib/secrets.ven"Cryptographically secure randomness, built on the interpreter's own builtin that draws entropy from the real operating system rather than a pseudo random source. It is deliberately narrow: a small set of helpers for generating secure tokens and values, not a full secrets management system.
