About this tool

What Kubernetes Secret does

Kubernetes stores values under data as Base64, not encryption. ParseNest extracts and decodes common Secret manifests directly in the browser.

Common uses

  • Debug a Secret copied from kubectl
  • Detect invalid Base64 values
  • Compare data and stringData behavior

Privacy and limitations

The manifest never leaves the browser. Avoid pasting service-account tokens into any tool you do not control.

Always validate security-sensitive output in the authoritative application or platform.

Frequently asked questions

Are Kubernetes Secrets encrypted?

Base64 is only encoding. Encryption at rest depends on cluster configuration.

What is stringData?

stringData accepts clear text at write time; the API server converts it into data.
