Trait Implementations

impl<'a> Hkdf for HkdfUsingHmac<'a>

fn extract_from_zero_ikm(&self, salt: Option<&[u8]>) -> Box<dyn HkdfExpander>

HKDF-Extract(salt, 0_HashLen)

fn extract_from_secret( &self, salt: Option<&[u8]>, secret: &[u8], ) -> Box<dyn HkdfExpander>

HKDF-Extract(salt, secret)

fn expander_for_okm(&self, okm: &OkmBlock) -> Box<dyn HkdfExpander>

Build a HkdfExpander using okm as the secret PRK.

fn hmac_sign(&self, key: &OkmBlock, message: &[u8]) -> Tag

Signs message using key viewed as a HMAC key.

fn extract_from_kx_shared_secret( &self, salt: Option<&[u8]>, kx: Box<dyn ActiveKeyExchange>, peer_pub_key: &[u8], ) -> Result<Box<dyn HkdfExpander>, Error>

HKDF-Extract(salt, shared_secret) where shared_secret is the result of a key exchange.

fn fips(&self) -> bool

Return true if this is backed by a FIPS-approved implementation.
