Information

What are SSH Keys?

SSH keys are cryptographic key pairs used for secure authentication to SSH servers. They consist of a public key (shared) and a private key (kept secret), providing a more secure alternative to password authentication.

Key types comparison:

RSA: Most widely supported, good for legacy systems
Ed25519: Modern, fast, and secure - recommended for new setups
ECDSA: Good balance of security and performance

Our SSH Key Generator creates cryptographically secure key pairs using your browser's WebCrypto API, ensuring your private keys never leave your device for maximum security.
