## Restoring encryption keys ## Restoring encryption keys
We used randomly generated keys for encryption and message signing in the provided examples, but real-world applications require consistent keys among clients. You can use the [@waku/utils](https://www.npmjs.com/package/@waku/utils) package to convert keys into a hexadecimal format for uniformity: We used randomly generated keys for encryption and message signing in the provided examples, but real-world applications require consistent keys among clients. Have a look at the [Key Pair Handling](https://github.com/waku-org/js-waku-examples/tree/master/examples/eth-pm/src/key_pair_handling) example, which demonstrates the secure storage and retrieval of key information from local storage using [Subtle Crypto](https://developer.mozilla.org/en-US/docs/Web/API/SubtleCrypto).
You can also use the [@waku/utils](https://www.npmjs.com/package/@waku/utils) package to convert keys into hexadecimal format:
```js ```js
import { bytesToHex, hexToBytes } from "@waku/utils/bytes"; import { bytesToHex, hexToBytes } from "@waku/utils/bytes";
import { generateSymmetricKey, generatePrivateKey } from "@waku/message-encryption";
// Generate random symmetric and private keys // Generate random symmetric and private keys
const symKey = generateSymmetricKey(); const symKey = generateSymmetricKey();
const privateKey = generatePrivateKey(); const privateKey = generatePrivateKey();
console.log(symKey, privateKey);
// Convert the keys to hexadecimal format // Convert the keys to hexadecimal format
const symKeyHex = bytesToHex(symKey); const symKeyHex = bytesToHex(symKey);
const privateKeyHex = bytesToHex(privateKey); const privateKeyHex = bytesToHex(privateKey);
console.log(symKeyHex, privateKeyHex);
// Restore the keys from hexadecimal format // Restore the keys from hexadecimal format
const restoredSymKey = hexToBytes(symKeyHex); const restoredSymKey = hexToBytes(symKeyHex);
const restoredPrivateKey = hexToBytes(privateKeyHex); const restoredPrivateKey = hexToBytes(privateKeyHex);
console.log(restoredSymKey, restoredPrivateKey);
``` ```

You have successfully encrypted, decrypted, and signed your messages using `symmetric` and `ECIES` encryption methods. Have a look at the [flush-notes](https://github.com/waku-org/js-waku-examples/tree/master/examples/flush-notes) example for a working demo.
