何时使用此配方

Every developer needs SSH keys for Git, server access, and CI/CD. Ed25519 keys are the modern standard — faster, smaller, and more secure than RSA.

常见问题

Ed25519 vs RSA — which should I use?

Ed25519 is recommended. It's faster, has smaller keys (256-bit vs 2048-4096 bit), and provides equivalent or better security. Only use RSA if your system doesn't support Ed25519.

Should I use a passphrase for my SSH key?

Yes, always. A passphrase protects the key if your device is compromised. Use ssh-agent to avoid typing it repeatedly.
