How can I generate SSH keys on Windows with PuTTY?

You can use PuTTY to generate your SSH keys. PuTTY is a free open-source terminal emulator that functions much like the Terminal application in Mac OS X in a Windows environment.

  1. Open the PuTTYgen program.
  2. For Type of key to generate, select SSH-2 RSA.
