@polkadot/wasm-crypto

Wrapper around crypto hashing functions

Usage

Install the package (also requires @polkadot/util for TextEncoder polyfills - not included here as a dependency to keep the tree lean)

yarn add @polkadot/wasm-crypto @polkadot/util

Use it -

const { u8aToHex } = require('@polkadot/util');
const { bio39Generate, bip39ToSeed, waitReady } = require('@polkadot/wasm-crypto');

async function main () {
  // first wait until the WASM has been loaded (async init)
  await waitReady();

  // generate phrase
  const phrase = bip39Generate();

  // get ed25519 seed from phrase
  const seed = bip39ToSeed(phrase, '');

  // display
  console.log('phrase:', phrase);
  console.log('seed:', u8aToHex(seed));
}
