![]() ![]() After this, the raw contents of the public key will be displayed alongside its fingerprint and a timestamp comment. You will be asked to move the mouse and press keys to improve the random number generation at the heart of SSH security. To generate a key pair with the PuTTY key generator, simply run puttygen.exe and click the Generate button in the window that appears. If you don’t already have Ubuntu on WSL, take a look at our Install Ubuntu on WSL tutorial. The puttygen.exe executable from PuTTY for Windows 7 or 8.1.The OpenSSH client built into Windows 10. ![]() RequirementsĪll you need is a PC running Windows and one of the following installed: Over the following few steps, we’ll guide you through the process of generating SSH keys using Ubuntu on WSL, OpenSSH, and PuTTY. But even without Ubuntu, SSH keys can also be generated with the free and open source OpenSSH client built into Windows 10 or with PuTTY for Windows 8.1 and earlier. Generating these keys from Linux is easy, and thanks to Ubuntu on WSL, you can follow the same process from Windows 10. 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. If you want to access your VPS from outside the Customer Portal (using any SSH client like OpenSSH ( ) or PuTTY ( )), you need to associate the generated SSH Key to the VPS.SSH, the secure shell, is often used to access remote Linux systems. Please refer to AUTHORIZED_KEYS FILE FORMAT section in the manual page for the OpenSSH server for a description of exact syntax of the " from=" option and the additional options. A good security precaution to mitigate the risk of a compromised private key is to add the " from=" option to restrict from which hosts/ip-addresses can be logged in. The " options" field can be used to place or lift restrictions on what can be done when that specific public key is used to access your virtual server. Pro tip: SSH2 public keys have the format of a single line with the fields: " options" " key-type" " base64-encoded public_key" " comment" where the " options" field is optional and typically omitted as seen in the screenshot above. The SSH key is generated and provides a fingerprint (short way to identify the long Public key).
