function generateKeySync
Usage in Deno
```typescript import { generateKeySync } from "node:node__crypto.d.ts"; ```
generateKeySync(type: "hmac" | "aes",options: { length: number; },): KeyObject
Synchronously generates a new random secret key of the given `length`. The `type` will determine which validations will be performed on the `length`.
```js
const {
generateKeySync,
} = await import('node:crypto');
const key = generateKeySync('hmac', { length: 512 });
console.log(key.export().toString('hex')); // e89..........41e
```
The size of a generated HMAC key should not exceed the block size of the
underlying hash function. See [createHmac](../.././node__crypto.d.ts/~/createHmac) for more information.
