[−][src]Struct hkdf::HkdfExtract

pub struct HkdfExtract<D> where
    D: Update + BlockInput + FixedOutput + Reset + Default + Clone,
    D::BlockSize: ArrayLength<u8>,
    D::OutputSize: ArrayLength<u8>,  { /* fields omitted */ }

Structure representing the streaming context of an HKDF-Extract operation

let mut extract_ctx = HkdfExtract::<Sha256>::new(Some(b"mysalt"));
extract_ctx.input_ikm(b"hello");
extract_ctx.input_ikm(b" world");
let (streamed_res, _) = extract_ctx.finalize();

let (oneshot_res, _) = Hkdf::<Sha256>::extract(Some(b"mysalt"), b"hello world");
assert_eq!(streamed_res, oneshot_res);

Implementations

impl<D> HkdfExtract<D> where
    D: Update + BlockInput + FixedOutput + Reset + Default + Clone,
    D::BlockSize: ArrayLength<u8>,
    D::OutputSize: ArrayLength<u8>, [src]

pub fn new(salt: Option<&[u8]>) -> HkdfExtract<D>[src]

Initiates the HKDF-Extract context with the given optional salt

pub fn input_ikm(&mut self, ikm: &[u8])[src]

Feeds in additional input key material to the HKDF-Extract context

pub fn finalize(self) -> (GenericArray<u8, D::OutputSize>, Hkdf<D>)[src]

Completes the HKDF-Extract operation, returning both the generated pseudorandom key and Hkdf struct for expanding.
