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
- Add the key-value pairs you want to store.
- This tool base64-encodes each value automatically.
- 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.
