The HKDF-SHA512 for HPKE KDF implementing KdfInterface.

When using @hpke/core, the instance of this class must be specified to the kem parameter of CipherSuiteParams instead of KdfId.HkdfSha512.

The KDF class can only derive keys of the same length as the hashSize. If you want to derive keys longer than the hashSize, please use hpke-js#CipherSuite.

Examples

Example 1

import {
  Aes256Gcm,
  CipherSuite,
  DhkemP521HkdfSha512,
  HkdfSha512,
} from "http://deno.land/x/hpke/core/mod.ts";

const suite = new CipherSuite({
  kem: new DhkemP521HkdfSha512(),
  kdf: new HkdfSha512(),
  aead: new Aes256Gcm(),
});
