Hit Enter to choose the default id_rsa filename, or type in your own along with the file path /Users//.ssh/ and then hit Enter. The key for my personal server is id_rsa_website. My GitHub SSH key is named id_rsa_github. Personally, I append a unique word after id_rsa that describes which remote machine the key will be used to connect to. If you decide to provide a unique filename, you must type in the complete file path along with the filename.If you plan on having multiple SSH keys, it’s best to name each one uniquely.The terminal instructs us to enter the name of a file in which we want our private key to be saved. refers to your local computer's current user. Enter file in which to save the key(/Users//.ssh/id_rsa) Step 2: Name your SSH keysĪfter entering the command, you should get this output: Generating public/private rsa key pair. Type man ssh-keygen in your terminal for more documentation. For instance, GitHub’s documentation for generating SSH keys uses the -b option, which lets you specify how many bits in the key. There are number of options you can add to the command above. It is just a type of key based on the RSA algorithm. The -t option specifies what type of key to generate. Run the following command: ssh-keygen -t rsa All commands will be entered through the terminal. These steps will help you set up SSH keys on your own private server. Note: SSH is widely available on most operating systems, but the instructions below have all been executed on Mac OS. If you own a private server and you’re not using SSH keys for authentication, it’s time to start thinking about it. If you are accessing a remote server for professional use, there’s a damn good chance you’re already using SSH keys. There are two situations that come to mind. No password needed! You can even add a passphrase for added security, but we’ll touch on that later. If there is a match, the connection is successful. When a user makes an attempt to connect to a remote machine via SSH, the protocol will check the user’s computer for the private key that matches the public key stored on the remote machine. The public key is stored on the remote machine. They are a cryptographic public/private key pair used for authentication. One of the main advantages to using SSH are SSH keys. Tools like telnet and ftp don’t provide this layer of security. It happens behind the scenes and will not interrupt your workflow. The process of data encryption is transparent. Only when the data reaches the remote server will it decrypt. All data sent from the client (your computer) is encrypted. SSH, or Secure Socket Shell, provides users with secure access to remote machines via an encrypted connection. They have been around for a long time, but their weakness lies in the fact that they lack security. Ftp provides a way to transfer files between computers. Telnet is a terminal program that allows users to login to remote computers on the same network. There are a variety of programs that give developers this functionality. Why? Maybe to send some data or to execute commands. Software developers need a way to access remote computers from their own.
