Struct HmacSha256Signer 

pub struct HmacSha256Signer { /* private fields */ }

HMAC-SHA256 signer for symmetric (pre-shared key) authentication.

Significantly faster than Ed25519 (~10x) since it only computes a keyed hash rather than elliptic curve math.

Implementations

impl HmacSha256Signer

pub fn new(key_bytes: &[u8], key_name: Name) -> Self

Create from raw key bytes (any length; 32+ bytes recommended).

Trait Implementations

impl Signer for HmacSha256Signer

fn sig_type(&self) -> SignatureType

fn key_name(&self) -> &Name

fn sign<'a>( &'a self, region: &'a [u8], ) -> Pin<Box<dyn Future<Output = Result<Bytes, TrustError>> + Send + 'a>>

fn sign_sync(&self, region: &[u8]) -> Result<Bytes, TrustError>

Synchronous signing — avoids Box::pin and async state machine overhead.

fn cert_name(&self) -> Option<&Name>

The certificate name to embed as a key locator in SignatureInfo, if any.

fn public_key(&self) -> Option<Bytes>

Return the raw public key bytes, if available.
