uselesskey-hmac

HMAC secret fixtures for testing — generates deterministic or random symmetric secrets for HS256, HS384, and HS512 workflows.

Part of the uselesskey workspace. Use the facade crate for the simplest experience, or depend on this crate directly for minimal compile time.

Usage

use uselesskey_core::Factory;
use uselesskey_hmac::{HmacFactoryExt, HmacSpec};

let fx = Factory::random();
let secret = fx.hmac("issuer", HmacSpec::hs256());

assert_eq!(secret.secret_bytes().len(), 32);

Specs

Deterministic Mode

use uselesskey_core::{Factory, Seed};
use uselesskey_hmac::{HmacFactoryExt, HmacSpec};

let seed = Seed::from_env_value("test-seed").unwrap();
let fx = Factory::deterministic(seed);

// Same seed + label + spec = same secret
let s1 = fx.hmac("issuer", HmacSpec::hs384());
let s2 = fx.hmac("issuer", HmacSpec::hs384());
assert_eq!(s1.secret_bytes(), s2.secret_bytes());
