I’m following this tutorial: digitalocean.com/community/tutorials/initial-server-setup-with-ubuntu-14-04

In step four “Add Public Key Authentication” it says “To generate a new key pair, enter the following command at the terminal of your local machine (ie. your computer)

I enter “ssh-keygen” in my “command prompt” and receive the following error:

‘ssh-keygen’ is not recognized as an internal or external command,
operable program or batch file.

What am I doing wrong?

Hi @bkozlowski, welcome to the community.

I have just the answer for your question. The tutorial you saw was assuming that both the host and the server machines ran linux.

ssh-keygen is a UNIX only command and of course doesn’t work on a Windows computer.

There is a way around this using a program called PuTTYGen. I have a video on youtube that shows how to use it and then use PuTTY+Pagent to load your ey in and connect to the server. I also show how to add the key to the server from a Windows computer.


Please let me know if you have any questions



These commands are for Linux/OS X systems. Since you’re running Windows, you’ll need to use PuTTy gen to generate the SSH keys and PuTTy to SSH into your Droplet.

This tutorial runs through creating SSH keys with PuTTY to connect to your virtual server.
