Why does Kubernetes store Secret data as Base64 encoded strings rather than encrypting them by default?

hard📝 Conceptual Q10 of 15

Kubernetes - Secrets

ABase64 encoding ensures data is safely transmitted and stored as text without altering content.

BBase64 encoding provides strong encryption to protect Secrets from unauthorized access.

CKubernetes automatically encrypts Secrets at rest, so Base64 is unnecessary for security.

DBase64 encoding compresses the Secret data to reduce storage size.

Step-by-Step Solution

Solution:

Step 1: Understand Base64 purpose
Base64 encoding converts binary data into ASCII text, making it safe for transmission and storage in YAML/JSON.
Step 2: Clarify encryption vs encoding
Base64 is not encryption; it does not provide confidentiality or security.
Step 3: Kubernetes default behavior
Kubernetes stores Secrets as Base64 encoded strings by default; encryption at rest is optional and configured separately.
Final Answer:
Option A -> Option A
Quick Check:
Base64 encodes data as text, not encrypts it [OK]

Quick Trick: Base64 encodes data for text safety, not security [OK]
