Key Comment

Optional comment to identify this key (e.g., user@hostname)

Keys are generated locally in your browser and never leave your device. To protect the private key with a passphrase, run ssh-keygen -p -f <keyfile> after saving it.

Key Type Information

RSA

Traditional algorithm with wide support. Larger key sizes provide more security but slower operations.

Ed25519

Modern, fast, and secure. Recommended for new deployments with good compatibility.

ECDSA

Elliptic curve based algorithm offering good security with smaller key sizes.
