How to add an SSL certificate to IIS?

nstalling an SSL certificate on Internet Information Services (IIS) involves importing the certificate into IIS and configuring your website to use HTTPS. The specific steps will vary depending on whether you are using a self-signed certificate or a certificate from a trusted Certificate Authority (CA).

For self-signed certificates:

1. Create a new folder to store your SSL certificate files.
2. Copy the SSL certificate file (usually named .crt) and the private key file (usually named .key) to the newly created folder.
3. Open the IIS Manager console. Navigate to the website you want to secure with SSL.
4. Right-click on the website and select “Bindings”.
5. Under “HTTP”, click on the “Add” button.
6. In the “Type” dropdown menu, select “HTTPS”.
7. In the “Protocol” dropdown menu, select “443”.
8. In the “Server Name” field, enter the hostname or IP address of your website.
9. In the “Certificate Path” field, browse to the folder containing your SSL certificate files and select the .crt file.
10. Click on “OK” to save the binding.

For certificates from a trusted CA:

1. Obtain the SSL certificate, the private key, and any intermediate certificates from the CA.
2. Import the certificate and private key into IIS using the “Add Certificate” wizard.
3. Browse to the location of the certificate files and select them.
4. Click on “Next” to import the certificate.
5. If you have intermediate certificates, you will need to import them as well.
6. Once all certificates are imported, the wizard will complete successfully.
7. Create a new binding for your website as described above, but select the imported certificate in the “Certificate Path” field.
8. Restart your IIS server to apply the changes.

Your website should now be using HTTPS and displaying a padlock icon in the address bar of web browsers.
