# @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 - ```js 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)); } ```
