Creating and binding self-signed SSL Certificates in IIS

SSL Binding

To create and bind a self-signed SSL certificate with PowerShell and IIS, you can follow these steps:

  1. Open a PowerShell session with administrative privileges.
  2. Generate a self-signed SSL certificate using the New-SelfSignedCertificate cmdlet. Here’s an example command:
$cert = New-SelfSignedCertificate -DnsName "" -CertStoreLocation "cert:\LocalMachine\My"

Make sure to replace “” with your actual domain name. The certificate will be stored in the “My” certificate store.

  1. Export the self-signed certificate to a .pfx file, which can be easily imported into IIS. Run the following command:
$pwd = ConvertTo-SecureString -String "password" -Force -AsPlainText
Export-PfxCertificate -Cert $cert -FilePath "C:\path\to\certificate.pfx" -Password $pwd

Replace “password” with your desired password, and “C:\path\to\certificate.pfx” with the desired path and filename for the exported certificate.

  1. Import the certificate into the local machine’s certificate store. Open the Certificates MMC snap-in (certlm.msc), and import the .pfx file into the “Personal” certificate store.
  2. Open the Internet Information Services (IIS) Manager.
  3. In the left-hand pane, select the desired website, and choose “Bindings” in the Actions pane on the right-hand side.
  4. Click “Add” to add a new binding.
  5. Select the appropriate settings for the new binding, such as type (HTTPS), IP address, port, and host name (matching the one specified during certificate generation).
  6. In the SSL certificate dropdown, choose “Select” and locate the self-signed certificate you imported in Step 4.
  7. Click “OK” to save the binding settings.

Your self-signed SSL certificate is now created and bound to the specified website in IIS. Please note that self-signed certificates are not trusted by default in web browsers and may trigger security warnings when accessed by users. It’s recommended to use trusted SSL certificates for production websites.
