@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 { bip39Generate, 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));
}
