SSH Key Best Practices
How to Use SSH Keys
- Generate key pair (public + private)
- Copy public key to server (
~/.ssh/authorized_keys) - Keep private key on your local machine (
~/.ssh/id_rsa) - Set correct permissions:
chmod 600 ~/.ssh/id_rsa
RSA vs Ed25519
RSA: Widely supported, battle-tested. Use 2048-bit minimum (4096-bit for maximum security).
Ed25519: Modern, faster, smaller keys. Excellent choice if your servers support OpenSSH 6.5+.
Security Tips
- Never share your private key
- Add passphrase for extra protection
- Rotate keys regularly
- Use different keys for different services
Common Use Cases
- GitHub/GitLab authentication
- AWS EC2, DigitalOcean servers
- SFTP file transfers
- CI/CD deployment pipelines
⚠️ Note: This is a demonstration tool. For production use, generate keys usingssh-keygen on your local machine for maximum security.
