Package Exports

@polkadot/wasm-crypto
@polkadot/wasm-crypto/crypto-polyfill

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@polkadot/wasm-crypto) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

@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(12);

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

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