Frequently Asked Questions
How do I generate an SSH key?
Run ssh-keygen -t ed25519 -C '[email protected]'. Press Enter for default location. Enter a passphrase (recommended). Your public key is at ~/.ssh/id_ed25519.pub.
Is SSH Key Generator Guide free?
Yes, this guide on ToolPix is 100% free with no signup or installation required.
Is my data safe?
This is an interactive guide — no actual keys are generated on our server. All commands run on your own machine.
Should I use Ed25519 or RSA?
Ed25519 is recommended — it's faster, more secure, and produces shorter keys than RSA 2048/4096. Use RSA 4096 only if the target system doesn't support Ed25519.
How do I copy my public key to a server?
Use ssh-copy-id user@server to automatically append your public key to ~/.ssh/authorized_keys on the server.
