## Example

```ts
declare const stack: Stack;
declare const flow: Flow;
declare const role: iam.IRole;
declare const secret: secretsmanager.ISecret;
declare const existingRouterOutput: RouterOutput;

// Flow output to router with transit encryption
const routerOutput = new FlowOutput(stack, 'RouterOutput', {
  flow: flow,
  output: OutputConfiguration.router({
    encryption: { role, secret },
  }),
});

// Flow source from router with transit encryption
const flowFromRouter = new Flow(stack, 'FlowFromRouter', {
  source: SourceConfiguration.router({
    routerOutput: existingRouterOutput,
    decryption: { role, secret },
  }),
});
```
