Core factory, deterministic derivation, and cache primitives for uselesskey test fixtures.

Most test suites should depend on the facade crate (uselesskey). Use uselesskey-core directly when building extension crates or when you need only the core primitives.

What It Provides

  • Factory in random and deterministic modes
  • Order-independent derivation from (domain, label, spec, variant)
  • Per-process cache for generated artifacts (powered by uselesskey-core-cache)
  • Generic negative helpers for corrupted PEM / truncated DER
  • Tempfile sinks when std is enabled (implemented in uselesskey-core-sink)

Features

Feature Description
std (default) Random mode, env seed helpers, tempfile sink, concurrent cache
default-features = false no_std deterministic derivation and negative helpers

Example

use uselesskey_core::{Factory, Mode, Seed};

// Deterministic mode: same seed always produces the same artifacts
let seed = Seed::from_env_value("ci-seed").unwrap();
let fx = Factory::deterministic(seed);

assert!(matches!(fx.mode(), Mode::Deterministic { .. }));

// Random mode: different keys each run (still cached per-process)
let fx = Factory::random();
