# Function: createDeviceKey()

```ts
function createDeviceKey(dbName?): Promise<DeviceKey>;
```

Defined in: [packages/core/src/identity/device-key.ts:26](https://github.com/leifriksheim/minca/blob/main/core/src/identity/device-key.ts#L26)

Makes a key for this device and remembers it. Non-extractable on purpose:
a CryptoKey survives IndexedDB, and no code path can turn it back into bytes.

## Parameters

| Parameter | Type | Default value |
| ------ | ------ | ------ |
| `dbName?` | `string` | `DB_NAME` |

## Returns

`Promise`\<[`DeviceKey`](https://minca.dev/api/core/interfaces/DeviceKey.md)\>
