SSH Key Generator: Create a Secure Key Pair Online

Reference: the former tool

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

1. Go to the SSH Key Generator page
2. Choose a key type: RSA (2048/4096) or ED25519
3. Optionally, add a comment (e.g., alex@vps)
4. Click “Generate” to receive your private and public keys
5. 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
