About this tool
SSH keys authenticate Git pushes, server logins and CI deploys. ssh-keygen works locally, but browser-based generation helps when you cannot run CLI tools or need a quick Ed25519 key with fingerprint.
Generates OpenSSH public keys, PEM private keys and SHA256 fingerprints using Web Crypto with node-forge fallback. Private keys never leave your browser.
How to use
Algorithm
Choose Ed25519 (default), ECDSA P-256 or RSA.
Comment
Set an email or host comment appended to the public key.
Copy keys
Copy public key to Git/host and store private PEM securely.
