What encoding mechanism is used in Kubernetes Secrets?

• A. Base64
• B. AES
• C. UTF-8
• D. JSON

Answer: (A)

Base64 is used. Kubernetes Secrets store their data as base64-encoded strings in the Secret object's data field, so values can be represented safely in text-based manifests. When you create a Secret, you can provide plain text via stringData and Kubernetes will encode those values to base64 in data. Viewing a Secret shows base64 strings, which you can decode to read the original content. Remember, this is encoding for transport and storage in YAML/JSON, not encryption for confidentiality; enable encryption at rest or use an external secret management solution if you need real protection.
