2. Versatility: PuTTY supports a wide range of protocols, including SSH, Telnet, SCP, and SFTP, making it suitable for various remote access and file transfer tasks.
3. User-Friendly Interface: PuTTY's straightforward interface makes it accessible to both beginners and advanced users. You don't need to be a command-line expert to use it effectively.
4. Reliability: PuTTY has a proven track record for its stability and consistent performance, making it a trusted tool for remote access.

Generating SSH Keys with PuTTYgen

Now, let's dive into the steps to set up a remote connection with PuTTY and generate SSH keys using PuTTYgen:

Step 1: Download PuTTY

The first step is to download PuTTY from its official website. You can choose the installer or the standalone executable, depending on your preferences. Once downloaded, run the installer to begin the installation process.

Step 2: Launch PuTTY

After the installation is complete, launch PuTTY by finding it in your list of installed programs or using the executable you downloaded. The PuTTY configuration window will appear.

Step 3: Configure the Connection

Now, it's time to configure your remote connection:



• Enter the Hostname or IP Address: In the PuTTY configuration window, you'll see a "Host Name (or IP address)" field. Enter the hostname or IP address of the remote server or device you want to connect to.
• Specify the Connection Type: Choose the appropriate connection type. For secure connections, select "SSH." For other types of connections, such as Telnet or serial connections, choose the corresponding option.
• Configure Other Connection Settings: Depending on your specific use case, you may need to configure additional settings like port numbers, SSH keys, or proxy settings. Refer to your system administrator or service provider for the correct configuration details.

Step 4: Save Your Session

To save time in the future, you can save your PuTTY session settings. Give your session a name in the "Saved Sessions" field, and click the "Save" button. This way, you can easily load your settings the next time you use PuTTY.

Step 5: Generate SSH Keys with PuTTYgen

PuTTYgen is a separate utility that comes with PuTTY and allows you to generate SSH key pairs for secure authentication. To generate SSH keys, follow these steps:

• Open PuTTYgen from the Start menu.
• Click the "Generate" button to create a new SSH key pair.
• Follow the on-screen instructions to generate your key. You can add a passphrase for added security.
• Save your public and private keys in a secure location.

Step 6: Open the Connection

Return to the PuTTY configuration window and click the "Open" button. PuTTY will establish a connection to the remote server using the settings you provided.

Step 7: Log In

Once the connection is established, you'll be prompted to log in. Enter your username and, if you set a passphrase, your passphrase.

Step 8: Enjoy Your Remote Connection

Congratulations! You've successfully set up a remote connection using PuTTY and generated SSH keys with PuTTYgen. You can now remotely administer servers, troubleshoot issues, transfer files securely, and perform various other tasks with the added layer of security provided by SSH keys.
