About this tool
Kubernetes Secret Generator is a free browser-based tool for creating Kubernetes Secret manifests from plain-text key-value pairs. Values are Base64-encoded locally in your browser and are not sent to a server.
Kubernetes Secret Generator
Generate Kubernetes Secret manifests with Base64-encoded values for passwords, tokens, keys, and other configuration data.
Secret Data
Enter plain-text values. They are Base64-encoded automatically for the generated Kubernetes Secret.
Generated Kubernetes Secret
Base64-encoded Secret manifest
apiVersion: v1
kind: Secret
metadata:
name: ""
type: Opaque
data: {}Security note: Values are processed locally in your browser. Kubernetes Secret manifests use Base64 encoding, which is not encryption. Do not treat Base64-encoded Secret values as safe for public repositories or untrusted environments.

Kubernetes Manifest Analyzer
Analyze Kubernetes manifests to inspect resources, workloads, replicas, containers, images, labels, selectors, references, and common configuration issues.

Kubernetes Quantity Converter
Convert Kubernetes CPU and memory quantities between millicores, cores, bytes, decimal units, and binary units.
Generate Kubernetes Secret YAML
Enter a Secret name, optional namespace, and one or more key-value pairs to generate a Kubernetes Secret manifest.
The generated YAML uses the Kubernetes v1 Secret format with an Opaque type and automatically converts each value to Base64.
Base64 Encoding and Kubernetes Secrets
Kubernetes Secret data is commonly represented as Base64-encoded values in YAML manifests. Base64 is an encoding format, not encryption.
Anyone who can access the Secret manifest or the encoded value may be able to decode it. Production workloads should use appropriate Kubernetes access controls and secret-management practices.
When to Use a Kubernetes Secret
- Store application usernames and passwords.
- Create Secret manifests for local Kubernetes development.
- Prepare configuration values for Kubernetes deployments.
- Generate Secret YAML for testing and troubleshooting.
- Convert plain-text key-value pairs into Kubernetes Secret data.
Are Secret Values Sent to a Server?
No. Secret generation and Base64 encoding happen entirely in your browser. The values you enter are not uploaded to ToolTunnel's servers.
Even though processing is local, avoid entering production credentials into browser tools unless your security policy explicitly permits it.
Frequently Asked Questions
▶What is a Kubernetes Secret?
A Kubernetes Secret is an API object used to store sensitive configuration data such as passwords, tokens, keys, and credentials.
▶Are Kubernetes Secrets encrypted?
Base64 encoding in a Kubernetes Secret manifest is not encryption. Kubernetes can protect stored Secret data using encryption at rest when the cluster is configured appropriately.
▶Why are Kubernetes Secret values Base64 encoded?
Kubernetes Secret data is represented using Base64 so arbitrary byte values can be safely represented in YAML and the Kubernetes API.
▶Can I create multiple Secret values?
Yes. Add as many key-value entries as needed and the generator will include each valid entry in the generated Secret manifest.
▶Are my Secret values uploaded to ToolTunnel?
No. The generator performs Base64 encoding locally in your browser and does not send the entered values to ToolTunnel's servers.
▶Can I use the generated YAML with kubectl?
Yes. The generated output is a standard Kubernetes Secret manifest and can be applied with kubectl after reviewing it and ensuring it meets your cluster's security requirements.
