Security Considerations
| Practice | Description |
|---|---|
| Never share publicly | Do not expose the key in client-side code, public repos, or logs |
| Secure storage | Use environment variables or a secrets vault (e.g., AWS Secrets Manager, HashiCorp Vault) |
| Rotate periodically | Follow your organization’s key rotation policy |
| No hardcoding | Never embed keys directly in source code |
