Struct HmacSha3_256 

pub struct HmacSha3_256;

HMAC-SHA3-256 message authentication code (32-byte tag).

Uses hmac::SimpleHmac because sha3 0.12’s types do not expose the block-level CoreProxy trait required by hmac::Hmac<D>.

Trait Implementations

impl Clone for HmacSha3_256

fn clone(&self) -> HmacSha3_256

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HmacSha3_256

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for HmacSha3_256

fn default() -> HmacSha3_256

Returns the “default value” for a type.

impl Mac for HmacSha3_256

fn name(&self) -> &'static str

Human-readable algorithm identifier (e.g. "HMAC-SHA-256").

fn key_len(&self) -> usize

Required key length (minimum acceptable length; MACs are often variable).

fn output_len(&self) -> usize

Output tag length in bytes.

fn mac(&self, key: &[u8], msg: &[u8], out: &mut [u8]) -> Result<(), CryptoError>

Compute a MAC tag for msg under key and write it into out.

fn verify(&self, key: &[u8], msg: &[u8], tag: &[u8]) -> Result<(), CryptoError>

Verify a MAC tag in constant time.

fn mac_to_vec(&self, key: &[u8], msg: &[u8]) -> Result<Vec<u8>, CryptoError>

Convenience: compute MAC and return the tag as a Vec<u8>.
