Using puttyGen, I've been able to get a openssh public key, that is printed in the window, but not a private key. I can only save a private key using the Save button, and it save a format that is not like the one we have using the.nix tool. How can we use windows tool in order to generate a VALID openssh compatible public and private key?

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

Over the following few steps, we’ll guide you through the process of generating SSH keys using both Ubuntu on Windows and PuTTY.
