@envelopa/argon2

Argon2id KDF provider for Envelopa.

Envelopa requires a KdfProvider at vault creation and unlock. This package supplies the default Argon2id implementation using WASM (hash-wasm), compatible with Node.js >= 20 and modern browsers.

Install

npm install @envelopa/argon2

You typically install this alongside envelopa:

npm install envelopa @envelopa/argon2

Usage

import { argon2id } from '@envelopa/argon2';
import { createVault, unlockVault } from 'envelopa';

const kdfProvider = argon2id();

const { header, session } = await createVault({
  password: 'user-password',
  kdfProvider,
});

const unlocked = await unlockVault({
  password: 'user-password',
  header,
  kdfProvider,
});

session.destroy();
unlocked.destroy();

Create one provider instance and reuse it across your application. Omit the kdf option in production to use Envelopa's default Argon2id parameters (64 MiB memory).
