Struct Blake3KeyedSigner 

pub struct Blake3KeyedSigner { /* private fields */ }

BLAKE3 keyed signer for authenticated high-throughput content.

Uses signature type code SIGNATURE_TYPE_DIGEST_BLAKE3_KEYED (7), reserved on the NDN TLV SignatureType registry, distinct from the plain BLAKE3 code on purpose (see the plain-vs-keyed rationale on the type code constants above). Uses a 32-byte secret key with BLAKE3’s built-in keyed hashing mode — faster than HMAC-SHA256 while providing equivalent security guarantees.

Implementations

impl Blake3KeyedSigner

pub fn new(key: [u8; 32], key_name: Name) -> Self

Create from an exact 32-byte key. The SignatureBlake3Keyed spec (docs/wiki/src/reference/blake3-signature-spec.md) requires keys to be exactly 32 octets; the [u8; 32] argument enforces this at compile time, eliminating any silent padding or truncation that would let a caller weaken the MAC by accident.

Trait Implementations

impl Signer for Blake3KeyedSigner

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.
