Dec 18, 2019 In this tutorial, we will walk through how to generate SSH keys on Ubuntu 18.04 machines. We will also show you how to set up an SSH key-based authentication and connect to your remote Linux servers without entering a password. Log on to your Ubuntu server with the credentials of the user that you want to create the private/public key for. Create a directory to store the public key using the commands below: $ mkdir /.ssh. Then, open the authorizedkeys file for editing using a nano editor by typing the commands below: $ nano /.ssh/authorizedkeys. If you don't already have an SSH key, you must generate a new SSH key.If you're unsure whether you already have an SSH key, check for existing keys. If you don't want to reenter your passphrase every time you use your SSH key, you can add your key to the SSH agent, which manages your SSH keys and remembers your passphrase.
SSH, the secure shell, is often used to access remote Linux systems. But its authentication mechanism, where a private local key is paired with a public remote key, is used to secure all kinds of online services, from GitHub and Launchpad to Linux running on Microsoft’s Azure cloud.
Generating these keys from Linux is easy, and thanks to Ubuntu on Windows, you can follow the same process from Windows 10. But even without Ubuntu, SSH keys can also be generated with the free and open source Windows application, PuTTy
Aug 09, 2018 Generate SSH Keys on Windows 10 with Ubuntu. Launch Bash on Ubuntu on Windows from the start menu and make sure SSH is installed by entering following command at the command prompt: sudo apt install ssh. The key generation process is identical to the process on a native Linux or Ubuntu installation.
Over the following few steps, we’ll guide you through the process of generating SSH keys using both Ubuntu on Windows and PuTTY.
