Crate uselesskey_hmac 

HMAC secret fixtures built on uselesskey-core.

Generates HMAC-SHA256, HMAC-SHA384, and HMAC-SHA512 symmetric secrets for testing. Supports deterministic and random modes.

Usage

The main entry point is the HmacFactoryExt trait, which adds the .hmac() method to Factory.

Examples

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

let fx = Factory::random();
let kp = fx.hmac("my-service", HmacSpec::hs256());
let secret = kp.secret_bytes();
assert_eq!(secret.len(), 32);

Deterministic Mode

Use deterministic mode for reproducible test fixtures:

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());

// Different labels produce different secrets
let s3 = fx.hmac("other", HmacSpec::hs384());
assert_ne!(s1.secret_bytes(), s3.secret_bytes());
