PuTTY is a free and open-source SSH and telnet client. It is primarily developed by Simon Tatham for Microsoft Windows but now it supports a wide variety of other operating systems. Public key authentication is a feature of PuTTY, in which, we can configure SSH Keys to allow password less logins to Linux machines from our PuTTY terminals.

In this article, we are configuring SSH Keys using PuTTYgen and then configure a CentOS 7 machine for password less logins by PuTTY client.

One Microsoft Windows based client and a CentOS 7 based server. Splinter cell conviction product key generator.

Generate SSH Keys using PuTTYgen:

If you want to use this key generated directly, I would suggest you use something like MINGW32/MINGW64, Cygwin, etc. Which allow you to use the ssh command in Command Prompt or some other terminal-like window. How to Generate SSH Keys on PuTTY. 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. Home Key-Based SSH Logins With PuTTY - Page 2 Scan your Web-Server for Malware with ISPProtect now. Get Free Trial.

PuTTYgen is included with PuTTY SSH client. Both are free and open source and distributed under MIT License. Therefore, it is available for free download at PuTTY official website.

We have already installed PuTTY SSH client on our MS Windows client.

Search and run PuTTYgen application.

Click on Generate button to generate a SSH Public/Private keys pair.

Meanwhile, we are required to scroll mouse in the area under the progress bar for randomization and generation of SSH Keys.

PuTTYgen has generated a SSH Public/Private keys pair.

Click on Save private key button to save the SSH Private Key locally.

Since, we are not defining any passphrase, therefore, PuTTYgen is displaying the above warning.

Ignore it and click on Yes.

We have saved our SSH Private Key in a local directory. You can also save your SSH Public Key in the same way, if you plan to use this same SSH Keys pair for more than one Linux machines.

Select the generated SSH Public Key and copy it to clipboard.

Configure SSH Keys for Password Less Logins to CentOS 7:

Connect to our CentOS 7 machine using PuTTY and insert SSH Public Key in ~/.ssh/authorized_keys file.

Now, open PuTTY and add a session for that CentOS 7 server.

Besides other settings, we are required to include our SSH Private Key as follows:

Save first and then open this session.

Our CentOS 7 server won’t prompt for a password this time. Generate a new ssh key on mac.

We have successfully configured SSH Keys using PuTTYgen for password less logins to Linux machines.

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).
The resulting generated files from the PuTTY Key Generator can be used to set up public key authentication with a remote server, allowing for more secure authentication over normal password based authentication (requires disabling password based authentication).
Download the PuTTY Key Generator
You can download puttygen from the following url:
https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html
Run puttygen.exe
When puttygen has loaded you will be presented with a screen such as this:
Generate the public and private keys
Click the “Generate” button on the main window to start the process of generating the key data.
While this is happening, you will need to move your mouse around in the blank area at the top of the application. This is used to help randomize the data used to generate the keys.
Once the progress bar has gone through, the public and private key data will have been generated, and you are ready to save the keys.
Saving the public and private keys
Public Key:
Simply press the “Save public key” button. This will be used on the remote host you want to be able to connect into remotely, using the private key.
Private Key:
You have the option to enter a passphrase if you want to make the key more secure. Enter that in, and the confirmed passphrase.
After thats done (or if you dont want to use a passphrase), simply press the “Save private key” button. Store this key in a safe place.
