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.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
