Single Step KDF (NIST SP 800-56C)

Single-Step Key Derivation function following NIST SP 800-56C revision 1, chapter 4 in TypeScript/JavaScript fully compatible with NodeJS.

Quick start

Add dependency to your proyect:

  • Yarn:

yarn add single-step-kdf-nist

  • npm:

npm i single-step-kdf-nist

Simple example:


import { singleStepKDF, hexToBytes, bytesToHex } from "single-step-kdf";

const hexSingleStepKDF = () => {
  const sharedSecretString = "test";
  const sharedSecret: Uint8Array = hexToBytes(sharedSecretString);
  const fixedInfo = JSON.stringify({ info: "some info" });

  const kdf = singleStepKDF(
    "sha256",
    sharedSecret,
    32,
    hexToBytes(fixedInfo)
  );

  return bytesToHex(kdf).toUpperCase();
};

Build

Use yarn to build the project.
