🔐 SSH Key Generator: Create a Secure Key Pair Online
SSH keys are used for secure passwordless access to VPS and servers. Instead of using passwords, you authorize with a public/private key pair. It’s safer, faster, and more convenient. With our online SSH key generator, you can quickly create RSA or ED25519 key pairs right in your browser.
🧩 What Are SSH Keys?
SSH keys are a cryptographic pair:
- 🔑 Private key — stays on your local machine and is never shared
- 🔓 Public key — is copied to the server in
~/.ssh/authorized_keys
Key-based authentication is resistant to brute-force and MITM attacks, especially when password login is disabled.
⚙ How to Generate SSH Keys Online
- 🧮 Go to the SSH Key Generator page
- 🔧 Choose a key type: RSA (2048/4096) or ED25519
- 🖊 Optionally, add a comment (e.g.,
alex@vps
) - 📥 Click “Generate” to receive your private and public keys
- 💾 Download both keys and store the private one securely
🔐 Using SSH Keys to Connect
1. Copy the public key to the server:
echo "ssh-rsa AAAA... user@host" >> ~/.ssh/authorized_keys
2. Set correct permissions:
chmod 700 ~/.ssh chmod 600 ~/.ssh/authorized_keys
3. Connect to the server:
ssh -i /path/to/private_key root@IP
💡 Security Best Practices
- 🔒 Never share your private key with anyone
- 🧊 Use a passphrase when generating your key
- 🛡 Disable password login on your server (via
sshd_config
) - 🚫 Don’t store keys in shared or cloud folders
- 📤 You can use
ssh-copy-id
to copy the public key to your server
