Trait Implementations

impl<T: Kdf> HpkeKdf for KdfWithDefaults<T>

const ID: KdfId = T::ID

Identifies the KDF algorithm per IANA.

impl<T: Kdf> Identified for KdfWithDefaults<T>

const OID: &'static Oid = T::OID

The algorithm’s OID.

impl<T: Kdf> Kdf for KdfWithDefaults<T>

type MaxOutput = <T as Kdf>::MaxOutput

The size in octets of the largest key that can be created with expand, expand_multi, or extract_and_expand.

type PrkSize = <T as Kdf>::PrkSize

The size in octets of a pseudorandom key used by this Kdf.

fn extract_multi<'a, I>(ikm: I, salt: &[u8]) -> Prk<Self::PrkSize>

where I: IntoIterator<Item = &'a [u8]>,

Identical to Kdf::extract, but accepts the ikm parameter as multiple parts.

fn expand_multi<'a, I>( out: &mut [u8], prk: &Prk<Self::PrkSize>, info: I, ) -> Result<(), KdfError>

where I: IntoIterator<Item = &'a [u8], IntoIter: Clone>,

Identical to Kdf::expand, but accepts the info parameter as multiple parts.

const MAX_OUTPUT: usize = <Self::MaxOutput>::USIZE

The size in octets of the largest key that can be created with expand, expand_multi, or extract_and_expand.

const PRK_SIZE: usize = <Self::PrkSize>::USIZE

Shorthand for PrkSize.

fn extract(ikm: &[u8], salt: &[u8]) -> Prk<Self::PrkSize>

A randomness extractor that extracts a fixed-length pseudorandom key (PRK) from the Input Keying Material (IKM) and an optional salt.

fn expand( out: &mut [u8], prk: &Prk<Self::PrkSize>, info: &[u8], ) -> Result<(), KdfError>

A Pseudo Random Function (PRF) that expands the PRK with an optional info parameter into a key.

fn extract_and_expand( out: &mut [u8], ikm: &[u8], salt: &[u8], info: &[u8], ) -> Result<(), KdfError>

Performs both the extract and expand steps.

fn extract_and_expand_multi<'a, Ikm, Info>( out: &mut [u8], ikm: Ikm, salt: &[u8], info: Info, ) -> Result<(), KdfError>

where Ikm: IntoIterator<Item = &'a [u8]>, Info: IntoIterator<Item = &'a [u8]>, <Info as IntoIterator>::IntoIter: Clone,

Performs both the extract and expand steps.
