Instructions

How to Use This Tool

1

Select Algorithm

Choose your preferred key algorithm: Ed25519 (highly recommended) or RSA (4096-bit).

2

Add Email Comment

Enter your email address to append a comment label (-C tag) to the public key.

3

Configure Filename

Specify a custom filename parameter to prevent overwriting existing keys in ~/.ssh/.

4

Run Locally

Copy the generated command string and paste it into your local terminal to create the key files.

Example

Generating a secure Ed25519 key for GitHub

Select the Ed25519 algorithm option, enter your email 'developer@work.com', and copy the command: 'ssh-keygen -t ed25519 -C "developer@work.com"'. Run this in your local bash shell to generate your secure key pair.

Questions

Frequently Asked Questions

Does this tool generate actual private keys in my browser?
No. This tool is an SSH key command helper that generates ready-to-run ssh-keygen terminal commands. You execute the command locally in your terminal to ensure private keys are never exposed.
Should I paste my private keys here to validate them?
No! You must never paste private SSH keys into any web interface. This tool only provides templates for local execution.
Are my command parameters private?
Yes. The command formatting logic runs entirely on your local device using JavaScript. No network requests are made with your settings.
