Now that you have an SSH key pair, you're ready to configure yourĪpp's system user so you can SSH or SFTP in using +-+ Configure an SSH/SFTP User for Your Key Method 1: Using ssh-copy-id You'll also be shown a fingerprint and 'visual fingerprint' of Your public key has been saved in /Users/yourname/.ssh/id_rsa.pub. Your identification has been saved in /Users/yourname/.ssh/id_rsa. The one named id_rsa.pub is your public key. The one named id_rsa is your private key. Enter passphrase (empty for no passphrase):Īfter you choose a password, your public and private keys will be

It's a good idea to use a password on your private key. Using a password means a password will be required to use the

Next, you'll be asked to choose a password. Enter file in which to save the key (/Users/yourname/.ssh/id_rsa): Press Enter to choose the default location. The default location is good unless you already have a key. You'll be prompted to choose the location to store the keys. It will look like this when you run it: laptop1:~ yourname$ ssh-keygen To generate an SSH key pair, run the command ssh-keygen. Private key from the server after you've generated it. Just remember to copy your keys to your laptop and delete your If you're using Windows, you can generate the keys on your server.

You should generate your key pair on your laptop, not on your server.Īll Mac and Linux systems include a command called ssh-keygen The SSH server and client programs take care of this for you. You don't have to do the math or implement the key exchange yourself.

Later, anytime you want to authenticate, the person (or the server)Īsks you to prove you have the private key that corresponds to.

Give someone (or a server) the public key.

Public key authentication works like this: It's like proving you know a password without having to show someone If you have the private key, you can prove you have it without showing These two keys have a very special and beautiful mathematical property: Keys come in pairs of a public key and a private key.Įach key pair is unique, and the two keys work together. Without needing to manage many different passwords.

However, using public key authentication provides many benefits when working If you use very strong SSH/SFTP passwords, your accounts are already Public key authentication is a way of logging into anĪ cryptographic key rather than a password.

You can generate a key pair using the RSA algorithm.← ServerPilot Docs How to Use SSH Public Key Authentication Overview In order to configure SSH key authentication, you will need to generate an SSH key pair on your local system. RequirementsĪ server running Ubuntu 20.04 operating system.Ī root password is set up on your server. In this post, we will show you how to set up public-key authentication to connect to a remote Linux server. You will need to copy this key to the remote server you intend to log in to. Public Key - The Public key is created with the name id_rsa.pub. Private Key - The private key is created with the name id_rsa and store on your local system. SSH key pairs are stored in plain-text files and consists of two parts: In this method, only users with a public key can able to connect to a server. It helps you to prevent brute force attacks. This method uses a cryptographic key pair for validation. Public Key Authentication is a secure method to log in to a remote server without providing a password. There are two ways to connect remote SSH servers, password-based authentication and key-based authentication.

It is often used by the system administrators to connect and manage remote Linux servers.

SSH is a free, open-source, and secure protocol used for managing remote servers via command-line interface.
