Which key types can I generate?

RSA and EC (elliptic-curve) key pairs, with selectable key sizes, all produced through the browser's Web Crypto API.

Are these keys safe to use on real servers?

Yes. The Web Crypto API uses a cryptographically secure generator. As with any key, keep the private half secret and never share it.

Standard PEM/OpenSSH-compatible output you can paste into authorized_keys or your Git host's SSH settings.

No. The pair is generated locally by the Web Crypto API and is never sent off your device — that is the whole point of generating it client-side.
