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 -

import { u8aToHex } from '@polkadot/util';
import { bip39Generate, bip39ToSeed, waitReady } from '@polkadot/wasm-crypto';

// 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));
