About SSH Keys
SSH keys provide a secure, passwordless way to authenticate with servers. Ed25519 is the modern recommended algorithm — faster and more secure than RSA with shorter keys.
Generate SSH key pairs for secure passwordless authentication. Supports Ed25519 (recommended) and RSA 4096-bit algorithms. Keys are generated entirely in your browser — never sent to any server.

Frequently Asked Questions
Ed25519 vs RSA — which is better?▼
Ed25519 is recommended — it is faster, more secure, and produces shorter keys. Use RSA only if your target system does not support Ed25519.
