In this guide, I’ll show you step by step how to secure your website by installing an SSL certificate in IIS. Having an SSL certificate is a must these days. It not only encrypts data for better security but also helps build trust with your visitors. Let’s dive in and get your website protected!

Step 1: Obtain the SSL Certificate

Ensure you have the valid SSL certificate file in .pfx format (PKCS#12 format). If the certificate is in .crt format, combine it with the private key to create a .pfx file.

Step 2 :- Convert a .crt File to .pfx Format

Friend’s just Follow these simple steps to convert your .crt file to .pfx format:

Prepare Your Private Key

• Open your private key file in a text editor like Notepad.
• Save the file with a .pem extension (e.g., privatekey.pem).
• While saving the file, ensure the file type is set to All Files to apply the .pem extension correctly.

Find a Trusted Converter Tool

• Search for “.crt to .pfx converter” on Google.
• Choose a reliable online tool for the conversion process. Click here to directly go to ssl converter.

Upload the Files

• Upload your .crt certificate file to the converter.
• Upload the .pem file you just created from the private key.

Start the Conversion

• Click on the Convert button.
• Wait for the tool to generate the .pfx file.

Download the .pfx File

• Once the conversion is complete, download the .pfx file.
• Your .pfx file is now ready to be used for SSL configuration.

Step 3 :- Install SSL Certificate in IIS Server
