How To Convert .pem To .ppk Keypair From AWS

To convert a .pem file to a .ppk file (PuTTY Private Key) for use with PuTTY or other tools that require .ppk files, you need to use PuTTYgen, a tool provided by PuTTY. Here’s how to do it:

Steps to Convert .pem to .ppk:

1. Download and Install PuTTYgen:
   • If you haven’t already, download and install PuTTY (which includes PuTTYgen) from PuTTY’s official website.
2. Open PuTTYgen:
   • After installation, open the PuTTYgen application. You can find it in your Start Menu under PuTTY or search for “PuTTYgen” directly.
3. Load the .pem File:
   • In PuTTYgen, click on Load.
   • 
     • In the file dialog, change the file type filter to All Files (.).
     • Navigate to the .pem file you downloaded from AWS (for example, the key pair you use to connect to your EC2 instance) and select it.
     • 
4. Convert to .ppk:
   • Once the .pem file is loaded, click on Save private key.
   • You will be prompted with a warning about saving the key without a passphrase. You can choose to either add a passphrase for extra security or save it without one.
   • Save the file with a .ppk extension (e.g., my-key.ppk).
5. Use the .ppk Key:
   • You can now use this .ppk file with PuTTY or other tools that require the .ppk format for authentication.

Example with PuTTY:

• When you want to connect to your EC2 instance using PuTTY, open the PuTTY application.
• Under the Session category, input the hostname or IP address of your EC2 instance.
• Go to Connection → SSH → Auth.
• Click on Browse and select the .ppk key you saved earlier.
• Click Open to initiate the connection to your EC2 instance.

That’s it! You’ve successfully converted your .pem file to a .ppk file for use with PuTTY or other tools that require the .ppk format.
