Struct HmacSigner 

pub struct HmacSigner { /* private fields */ }

HMAC-SHA256 (HS256) implementation of TokenSigner and TokenVerifier.

Cloning is cheap — the secret is stored behind Arc.

Implementations

impl HmacSigner

pub fn new(secret: impl AsRef<[u8]>) -> Self

Creates a new HmacSigner with the given secret.

Trait Implementations

impl Clone for HmacSigner

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl From<HmacSigner> for Arc<dyn TokenSigner>

fn from(signer: HmacSigner) -> Self

Converts to this type from the input type.

impl From<HmacSigner> for Arc<dyn TokenVerifier>

fn from(signer: HmacSigner) -> Self

Converts to this type from the input type.

impl TokenSigner for HmacSigner

fn sign(&self, header_payload: &[u8]) -> Result<Vec<u8>>

Signs header_payload and returns the raw signature bytes.

impl TokenVerifier for HmacSigner

fn verify(&self, header_payload: &[u8], signature: &[u8]) -> Result<()>

Verifies that signature was produced by signing header_payload with the same key.

fn algorithm_name(&self) -> &str

Returns the JWT algorithm name used in the token header (e.g., "HS256").
