Enum Algorithm 

pub enum Algorithm {
    Rs256,
    Es256,
    Hs256,
}

JWT signing algorithm.

The variant determines both the JWT alg header value and the expected format of the key data passed to JwtSigner::new.

Variants

Rs256

RSASSA-PKCS1-v1_5 with SHA-256 (RS256).

Key data: PKCS#8 PEM (-----BEGIN PRIVATE KEY-----). Typical RSA modulus size is 2048 bits. Used by GitHub App, Google Cloud service accounts, and most server-to-server JWT flows.

Es256

ECDSA on curve P-256 with SHA-256 (ES256).

Key data: PKCS#8 PEM. Used by Apple (Sign in with Apple, APNs Provider API) and other services that prefer compact signatures.

Hs256

HMAC with SHA-256 (HS256).

Key data: raw shared-secret bytes. Used for symmetric authentication schemes such as custom gateways and Supabase.
