Generating SSH Keys with PuTTYgen on Windows 10

When it comes to setting up secure connections between your local machine and a remote server, Secure Shell (SSH) keys play a crucial role. In this guide, we'll walk you through the process of generating SSH keys using PuTTYgen, a popular tool for Windows 10.

Getting Started with PuTTYgen

PuTTYgen is a free utility that comes bundled with the PuTTY client, which is an SSH client for Windows. To start, download and install PuTTY from the official website. Once installed, you'll find PuTTYgen in your Start menu or by searching for 'Puttygen' in the Run dialog box.

To generate an SSH key pair, follow these steps:

1. Launch PuTTYgen and click on the 'Generate' button.

2. Move your mouse around the area below the progress bar to generate random noise.

3. Type a passphrase in the Key passphrase field and confirm it by typing the same passphrase in the Confirm passphrase field.

Once you've generated your key pair, you can save it as an OpenSSH key or a PuTTY private key. Make sure to save both files in a secure location, such as an encrypted folder or a USB drive.

Understanding SSH Keys

In the world of SSH, keys are used to authenticate users and establish secure connections between servers. Public-private key pairs work by using a public key to encrypt data and a private key to decrypt it. When you generate an SSH key pair with PuTTYgen, you're creating a pair of files that contain your public and private keys.

Using Your SSH Key with PuTTY

To use your generated SSH key with PuTTY, follow these steps:

1. Launch PuTTY and navigate to the 'Connection' menu.

2. Select 'SSH' and then click on 'Auth'.

3. Click on 'Browse' next to 'Private key file for authentication' and select your private key file.

With your SSH key set up in PuTTY, you can now use it to log in to your remote server using the 'ssh' command or by opening a new session with PuTTY.

Generating SSH keys with PuTTYgen is a straightforward process that provides an additional layer of security for your connections. By following these steps, you can create and manage SSH key pairs on your Windows 10 machine, enabling you to securely access remote servers and workstations.
