Struct HmacSignatureVerifier 

pub struct HmacSignatureVerifier { /* private fields */ }

HMAC-SHA256 signature verifier.

Signs messages with HMAC-SHA256 and uses constant-time comparison during verification to prevent timing attacks.

Implementations

impl HmacSignatureVerifier

pub fn new(key: &[u8]) -> Self

Create a signature verifier, deriving from a key of arbitrary length.

pub fn from_key_str(key: &str) -> Self

Create from a string key.

Trait Implementations

impl SignatureVerifier for HmacSignatureVerifier

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

Sign a message.

fn verify(&self, message: &[u8], signature: &[u8]) -> bool

Verify a message signature (constant-time comparison).
