Methods

`impl Hkdf`
[src]

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

Usage examples:

use orion::hkdf::Hkdf;
use orion::functions;

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

let prk = Hkdf::hmac_SHA512.hkdf_extract(&salt, &key);
let d_key = Hkdf::hmac_SHA512.hkdf_expand(&prk, &info, 50);

`fn hkdf_extract(&self, salt: &[u8], ikm: &[u8]) -> Vec<u8>`
[src]

The HKDF Extract step. Returns a PRK (HMAC) from passed salt and IKM.

`fn hkdf_expand(&self, prk: &[u8], info: &[u8], okm_len: usize) -> Vec<u8>`
[src]

The HKDF Expand step. Returns an HKDF.
