What is SSH Keys?

An SSH key generator that produces an RSA key pair in the browser, outputting the public key in OpenSSH format and the private key in PEM.

How it works

An RSA key pair is generated with the Web Crypto API; the public key is converted to OpenSSH format and the private key exported as PKCS#8 PEM.

Frequently asked questions

Should I use a browser-generated key in production?

Browser-generated private keys should be treated as demo/throwaway. For production keys, prefer ssh-keygen in a trusted terminal.
