## 2. Create Kubernetes secret

[Kubernetes secrets](https://kubernetes.io/docs/concepts/configuration/secret) are intended to hold sensitive information.
We'll use secrets to hold the TLS certificate and key. To create a secret, update the paths to `private.key` and `public.crt`
below.

Then type

```sh

/**
 * Secure credential storage with encryption at rest.
 *
 * Provides secure storage of passwords and other sensitive credentials
 * using AES-GCM encryption with PBKDF2 key derivation.
 *
 * Features:
 * - Encrypts credentials at rest using AES-256-GCM
 * - Uses PBKDF2 for key derivation from master password
 * - Secure wiping of sensitive data
 * - Thread-safe operations
 * - Protection against timing attacks

Latency sensitive applications may notice an increased latency due to a request to the external plugin upon every authenticated request to MinIO. User are advised to provision their infrastructure such that latency and performance is acceptable.
