Kubernetes Secret YAML Generator

Generate a Kubernetes Secret manifest with base64-encoded values - entirely in your browser, values never leave your device.

Add key-value pairs to store as a Secret - this tool base64-encodes them and generates the manifest entirely in your browser.

Everything below is encoded entirely in your browser - nothing you type is sent to or stored on any server. That said, avoid pasting real production credentials into any browser-based tool unless truly necessary, and remember: base64 is encoding, not encryption - anyone who can read the Secret can trivially decode it.

Base64 is an encoding, not encryption - anyone with API access to read the Secret (or the raw manifest file) can trivially decode the values back to plain text.

What Is a Kubernetes Secret?

A Kubernetes Secret is structurally almost identical to a ConfigMap, but intended for sensitive values (passwords, tokens, keys) - its data field values are stored base64-encoded rather than plain text.

Why Use This Tool?

Manually base64-encoding several values and assembling the YAML by hand is tedious and error-prone. This tool does the encoding and generates the manifest for you, and does so entirely in your browser - nothing you enter is transmitted anywhere.

How to Use It

  1. Add the key-value pairs you want to store.
  2. This tool base64-encodes each value automatically.
  3. Copy the generated Secret YAML.

Important Notes

Base64 encoding is not encryption - it's trivially reversible, and a Secret's real protection comes from Kubernetes RBAC controlling who can read it, and (ideally) encryption at rest on the cluster. Avoid pasting real production credentials into any browser-based tool unless you've verified exactly how it processes your input - this one processes everything locally and transmits nothing, but always be cautious with genuinely sensitive values.

Frequently Asked Questions

No. Base64 is only an encoding and anyone can decode it. Protect Secrets with RBAC, enable encryption at rest, and never commit real Secret manifests to Git.

No. Encoding happens entirely in your browser, so the values never leave your device.

data expects base64-encoded values; stringData accepts plain text and Kubernetes encodes it for you when the Secret is created.
