One effective way of securing SSH access to your cloud server is to usea public-private key pair. This means that a public key is placed onthe server and a private key is placed on your local workstation.Using a key pair makes it impossible for someone to log in by using justa password, as long as you set up SSH to deny password-basedauthentication.
This article provides steps for generating RSA keys by using PuTTYgen onWindows for secure SSH authentication with OpenSSH.
Generate keys
Navigate to the private key in your file system and select it. The public key is redisplayed again in the appropriate format. Now that you have your generated key pair saved on your computer and ready to use, you can: Add your public key to your DigitalOcean account to be able to embed it in new Droplets on creation.
You have an RSA private key as a result of the public and private key self-generated key pair This tutorial will not convert on how to generate a pair of public and private keys. Because PuTTY doesn’t understand the idrsa private key we need to convert the private key to a putty client format in.ppk. Generate SSH Keys on Windows with PuTTYGen (the PuTTY Key Generator) June 9, 2017 Windows To generate SSH public and private key pairs on Windows, one of the easiest tools to use, is the PuTTY Key Generator “puttygen.exe” (which can be downloaded from here ).
In Windows, use PuTTYgen to generate your public and private keys.
- If needed, download PuTTYgen from the PuTTY download page.(PuTTYgen might have been installed previously with PuTTY or WinSCP.)
- Launch the program, and then click the Generate button.The program generates the keys for you.
- Enter a unique key passphrase in the Key passphrase andConfirm passphrase fields.For additional information about using passphrases,see Log in with a SSH Private Key on Windows.
- Save the public and private keys by clicking the Save public keyand Save private key buttons.
- From the Public key for pasting into OpenSSH authorized_keys filefield at the top of the window, copy all the text (starting with ssh-rsa)to your clipboard by pressing Ctrl-C.You need this key available on your clipboard to paste eitherinto the public key tool in the Control Panel or directly into theauthorized keys on your cloud server.
Use the key pair
You can use the RSA key pair in the following ways.
Specify your SSH key when creating a new cloud server
When you create a cloud server, you can assign a public key from the list of keys.If your key is not already in the list, you may add it, and then assign it.
Add a new public key to the list
- Under Advanced Options on the Create Server page, click Manage SSHKeys.
- Select public key for the cloud server from the SSH Keys listand click Add Public Key.
- Enter the key name, select the region, and paste the entire publickey into the Public Key field. Then click Add Public Key.
- Go back to the Create Server page, and confirm that your key is listedin the SSH Key list.
Assign a public key
- Under Advanced Options on the Create Server page, select the publickey you want to use from the SSH key drop-down menu.
- When you are done specifying the all the other details for the server,click Create Server.
Assign your SSH Key to an existing cloud server
To make use of your newly generated RSA key pair, you must tell PuTTY touse it when connecting to your cloud server.
- To edit the file (or create it), run the following command on the cloud server:
- Paste the text onto its own line in the file.You must have the key available in your clipboard to paste it. The key and itsassociated text (the ssh-rsa identified at the start and the comment at the end)must be on one line in the file. If the text is word-wrapped onto multiple linesan error might occur when connecting.
- If you created the authorized_keys file, change its permissionsafter you’re done editing it by running the following command:
- Open PuTTY, and go to the SSH > Auth section.
- Browse to the location of the key file, and load the private key.
- Go to the Session page, and save the session. This saves the configurationso that PuTTY uses the key every time that you connect to your cloudserver.
After you save your session, your key is loaded automatically when youconnect to your server.

With security becoming increasingly important in today’s modern world of information theft and privacy concerns, keeping your server safe and secure has almost become a necessity. While several methods exist to properly secure your server, from using a long password to two-factor authentication, they can be quite a hassle to set up and use on a day-to-day basis. However, private keys offer a good balance between convenience and security.
In an earlier article, we saw how to generate a private/public key pair. We also saw that we need to use the “puttygen” tool to convert it into a format that’s accepted by a lot of software programs like WinSCP for SFTP access, and so on.
In this article, we’ll show you how to use a private key to allow you to log into a server without the need for typing in a password. This comes with several benefits. In order to set up logging in using a private key on your server, you will have to have done the following first in order for this to work:
- Generated a private/public key pair on your server
- If via the command line, you’ve put your private key into the “authorized_keys” file
- You’ve downloaded your private key
- You’ve converted it to the “PPK” format

Why Not Use a Password Instead?
When logging in via SSH, you can choose to use a password or a key file. Authentication usually hinges on one or more of three things:
- Something you know
- Something you have
- Something you are
A password belongs to the first category – something you know. And something you know can also be known by other people. Something you know can also be guessed. In general, passwords are slowly being phased out for serious security applications – or at the very least, they’re being combined with other forms of authentication.
Something you have, on the other hand, is a lot more difficult to fake. A private key on your local computer isn’t as vulnerable as a password. Passwords are also susceptible to “man-in-the-middle” attacks, where a hacker can intercept your password in plain text when you connect to the server and then use it whenever they want.
A private key connection, however, doesn’t allow man-in-the-middle attacks. Your private key is never sent over the public network. By working through a complex sequence of cryptographic algorithms, SSH key authentication is completely safe from snooping.
For these reasons, you want to use private key authentication whenever you can.
Step 1: Downloading PuTTY
A prerequisite to using private keys to log in would be that you need to convert the private key you downloaded from your server into a “PPK” file for use with 3rd party programs. One such program is called PuTTY, and it’s something of a standard connection tool in the server world. You can download it from here, and grab the version that suits you best, like this:
Download PuTTY From their Website
It’s a standalone program and doesn’t require any installation process. Microsoft office 2016 product key generator free download. So once you download it, you can just run it and get started right away.
Step 2: Configuring Your Credentials with PuTTY
Generated A Putty Private Keys
To set up PuTTY, run the executable file and after the interface opens, click the “Sessions” tab on the left (it should be selected by default). Now enter your hostname and the port number. Normally the port number for SSH is 2222, but our test server is set to use a custom port to make it difficult for attackers to randomly make attempts to log in. Just replace 7022 from the screenshot below with the port number used by your server:
If you’re hosting with a hosting provider that has a custom SSH port, make sure you check with them as to what their port is.
Step 3: Specify the Private Key
Now expand “SSH” on the left-hand side, and click “Auth”, as shown here:
Creating Putty Private Key
Select the Private Key from its Location
Click “Browse” and navigate to the location of your private key. Select it (it should be in the .PPK format) and you’re done! Click “Open” and an SSH window should open up. Enter the username with which you generated your private key and if all goes well, it should log in like this:

And that’s it – you’ve successfully opened an SSH session with private key authentication using PuTTY.

Of course, you don’t have to create and set up your private and public key pair on your Ubuntu 16.04 VPS if you use one of our Linux VPS Hosting services, in which case you can simply ask our expert Linux admins to set up the SSH keys for you.
