Ssh Key Hetzner
If you’re looking to enhance the security of your Hetzner server, using SSH keys is a great way to do it. SSH keys provide a more secure way of logging into your server compared to traditional password authentication. In this article, we’ll guide you through the process of setting up SSH keys on your Hetzner server.
What are SSH keys?
SSH keys are a pair of cryptographic keys that can be used for secure authentication. The key pair consists of a public key and a private key. The public key is placed on servers you want to access securely, and the private key is kept on your local computer. When you try to log in to a server, your computer uses the private key to create a digital signature, which is verified by the server using the public key. This way, you can log in without the need to enter a password.
Generating SSH keys
To generate SSH keys, you can use the `ssh-keygen` command in your terminal. Open your terminal and run the following command:
ssh-keygen -t rsa -b 4096
This command will generate a new RSA key pair with a key length of 4096 bits. You can also choose a different encryption algorithm or key length if you prefer by modifying the command.
Adding your SSH key to Hetzner
Once you have generated your SSH keys, the next step is to add your public key to your Hetzner server. You can do this by logging into your server via SSH and opening the `authorized_keys` file located in the `~/.ssh/` directory. Copy the contents of your public key file (usually `id_rsa.pub`) and paste them into the `authorized_keys` file.
Logging in with SSH keys
Now that your SSH key is added to your Hetzner server, you can log in using SSH keys. When you try to connect to your server via SSH, your local computer will automatically use your private key to authenticate with the server. If everything is set up correctly, you should be able to log in without entering a password.
Conclusion
Using SSH keys on your Hetzner server is a great way to enhance security and streamline the authentication process. By following the steps outlined in this article, you can set up SSH keys on your server and enjoy the benefits of secure, passwordless authentication. Give it a try and see the difference it can make!
