PuTTY is probably the most famous software using this format and nearly everyone on Windows uses it. To give these windows ssh users access to a Linux system, SFTP server, Git repository or other systems that use the OpenSSH key format, you need to convert an SSH2 public key into the OpenSSH format. This article describes how to do exactly that. How to Convert OpenSSH keys to Putty (.ppk) on Linux June 3, 2019 by Hayden James, in Blog Linux. PuTTYgen is an key generator for creating SSH keys for PuTTY. PuTTYgen is comparable in certain respects to the ssh-keygen tool. PuTTYgen can be used to create public and private key pairs (in.ppk file format). Convert your private key using PuTTYgen. Locate the private key (.pem file) for the key pair that you specified when you launched the instance. Convert the.pem file to a.ppk file for use with PuTTY. Save the text file in the same folder where you saved the private key, using the.pub extension to indicate that the file contains a public key. If you or others are going to use an SSH client that requires the OpenSSH format for private keys (such as the ssh utility on Linux), export the private key: On the Conversions menu, choose Export. Before completing the steps in this section, make sure that you either have SSH key-based authentication configured for the root account on this server, or preferably, that you have SSH key-based authentication configured for an account on this server with sudo access. This step will lock down password-based logins, so ensuring that you have.

SSH keys are one of the most secure SSH authentication options. It is definitely more secure than the usual SSH password authentication. Therefore, it is highly recommended to use SSH Key authentication method for connections to your servers.

With password authentication, you can connect to your server from any location, you only need to fill in your password. However, if your password gets leaked, it is a major risk as anyone who knows your password will be able to get into the server.

SSH Key authentication only allows connections from clients whose key matches the one on the server. Basically, you generate a key pair (private key and public key). The private key is placed on your local machine and the public key is uploaded to the server. When connecting to the server, a validation of these two keys is made and if the key pair passes the validation you are allowed to connect. Of course, you can upload keys of multiple users so that you or other authorized users would be able to connect to the server from different computers.

As you can see this is a much safer connection method. In this tutorial, we will focus on Windows users who use PuTTY for connections to the server and show how to generate PuTTYSSH Keys. If you want to generate SSH Keys on Linux or Mac, see this tutorial.

What you’ll need

Before you begin this guide you’ll need the following:

Access to your Linux server / VPS
PuTTY and PuTTYgen installed on your computer (Download here)

Step 1 — Downloading PuTTYgen

Most of you have PuTTY installed on your computers already, however, to generate SSH Keys you also will need PuTTYgen.

Download PuTTYgenhere
You should be able to see this file downloaded:

No installation is required for PuTTYgen, it will run when you execute the file.

Step 2 — Generating your SSH Key pair

Open up PuTTYgen by double clicking on the puttygen.exe file you have downloaded in Step 1.
You should be able to see a window like this:
Before generating your SSH Key pair, you can edit some settings, for example, key length, however, in most cases the default options will work just fine.
Generate your SSH Key pair by clicking the Generate button.
When the progress bar starts loading, move your mouse randomly across the area to load up the bar and generate your key pair.
Your public SSH key will be displayed on the screen:
For additional security it is highly recommended to think of a passphrase for your SSH key (However, you can also leave it empty):
Save your private key to any desired location on your computer and name it anything you like.
Save your public key to the same location on your computer and name it anything you like.

And that is it, you have generated your SSH Key pair. The private key will stay on your computer (do not provide it to anyone) while your public key needs to be uploaded to the server you wish to connect to.

Step 3 — Setting up your private key on PuTTY

In order for the server to recognize your computer when connecting from PuTTY, you need to attach the private key to PuTTY.

Open up PuTTY.
Navigate to Connection -> SSH -> Auth in the left sidebar.
Browse for your private key file in the field Private key for authentication
Select the private key file with .ppk ending and click Open.

Step 4 – Adding public key to server

Lastly, you need to upload your public key to the server:

On your local computer, open public key file (id_rsa.pub) you generated in Step 2 with any text editor and copy its contents (public key).
Connect to your VPS using Putty. See this guide for detailed steps.
If .ssh folder does not exist, create it together with authorized_keys file with the following command:
mkdir ~/.ssh | touch ~/.ssh/authorized_keys
Secure SSH Key file by changing permissions:
chmod 0700 ~/.ssh; chmod 0644 ~/.ssh/authorized_keys
Open authorized_keys file with vim text editor:
vim ~/.ssh/authorized_keys
Press i key on your keyboard and right mouse button to paste the public key.
Press Esc button and type in :x, hit Enter button. This command will save changes made to the file.

That is it, you can now use SSH keys instead of SSH password authentication to connect to your VPS.

Conclusion

You have learned how to generate PuTTY SSH Keys using PuTTYgen. This will make your connection to the server a lot more secure and convenient as you will not need to fill in the password each time. We recommend using this way of SSH authentication at all times and disable password authentication for good to completely secure your server. To find out how to completely disable SSH Password authentication on your server and use SSH Key authentication instead, follow this tutorial: How to disable SSH Password authentication on VPS.

Introduction

SSH can handle authentication using a traditional username and password combination or by using a public and private key pair. The SSH key pair establishes trust between the client and server, thereby removing the need for a password during authentication. While not required, the SSH private key can be encrypted with a passphrase for added security.

The PuTTY SSH client for Microsoft Windows does not share the same key format as the OpenSSH client. Therefore, it is necessary to create a new SSH public and private key using the PuTTYgen tool or convert an existing OpenSSH private key.

Requirements

PuTTY SSH client for Microsoft Windows
Remote server accessible over OpenSSH

Install PuTTY and PuTTYgen

Both PuTTY and PuTTYgen are required to convert OpenSSH keys and to connect to the server over SSH. These two tools can be downloaded individually or, preferably, as a Windows installer from the PuTTY Download Page.

Once the PuTTY Windows installer is downloaded, double-click the executable in the Download folder and follow the installation wizard. The default settings are suitable for most inst
