@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 -

import { u8aToHex } from 'https://deno.land/x/polkadot@0.2.40/util/mod.ts';
import { bip39Generate, bip39ToSeed, waitReady } from 'https://deno.land/x/polkadot@0.2.40/wasm-crypto/mod.ts';

await waitReady();

const phrase = bip39Generate(12);

const seed = bip39ToSeed(phrase, '');

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