Trait encapsulating implementations of the HMAC constructions for a given hasher type.

Required Methods

fn bits(&self) -> usize

The number of bits in the digest length of the HMAC type.

fn kdf_hash_length( &self, key: &[u8], label: &str, context: &[u8], bits: usize, ) -> Vec<u8>

See: kdf_hash_length()

See: hkdf_extract()

fn hkdf_expand(&self, prk: &[u8], info: &str, length: usize) -> Vec<u8>

See: hkdf_expand()

fn confirm(&self, key: &[u8], counter: u16, data: &[&[u8]]) -> Vec<u8>
