Methods

impl Hkdf

HKDF (HMAC-based Extract-and-Expand Key Derivation Function) as specified in the RFC 5869.

Usage examples:

use orion::hkdf::Hkdf;
use orion::util::gen_rand_key;

let key = gen_rand_key(10);
let salt = gen_rand_key(10);
let info = gen_rand_key(10);

let dk = Hkdf { salt: salt, data: key, info: info, hmac: 256, length: 50 };
dk.hkdf_compute();

pub fn hkdf_extract(&self, data: &[u8], salt: &[u8]) -> Vec<u8>

Return HMAC matching argument passsed to Hkdf.

pub fn hkdf_compute(&self) -> Vec<u8>

The HKDF Expand step. Returns an HKDF.
