# @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));
|
|
}
|
|
```
