SSH Key Generator
Generate SSH key pairs in OpenSSH format with SHA-256 fingerprints entirely in your browser.
Generate SSH key pairs in your browser
SSH keys authenticate you to servers and Git hosts without passwords. This generator creates Ed25519, ECDSA P-256, or RSA key pairs in OpenSSH format with a SHA-256 fingerprint. Private keys never leave your device.

Frequently Asked Questions
Which algorithm should I choose?
Ed25519 is the modern default: short keys, fast signatures, and strong security. Use RSA 4096 only when a legacy system requires it.
Where do I put the public key?
Add the public key line to ~/.ssh/authorized_keys on a server or to your Git hosting account SSH settings.
Is browser generation safe?
Keys are created locally. For high-assurance production access, many teams still prefer ssh-keygen on a trusted machine with a passphrase.
What is the fingerprint for?
The SHA-256 fingerprint helps you confirm you are using the correct public key when comparing server or host key listings.
