## 12. Security Considerations

### 12.1 Handle State Encryption
```java
public class SecureHandleStorage {
    private final SecretKey encryptionKey;
    
    public void saveEncrypted(HandleInfo handle, Path file) throws Exception {

    /**
     * The key for user roles in the request attribute.

- New Metrics Added for Encryption Configuration Controller
  
  This release adds new metrics to the Encryption Configuration Controller to help monitor the automatic reloading of encryption configuration. The new metrics include:
  
  - `apiserver_encryption_config_controller_automatic_reload_failures_total`: Total number of failed automatic reloads of encryption configuration.

  - The `--experimental-encryption-provider-config` flag is deprecated in favor of `--encryption-provider-config`. The old flag is accepted with a warning but will be removed in 1.14. ([#71206](https://github.com/kubernetes/kubernetes/pull/71206), [@stlaz](https://github.com/stlaz))
