Windows - Set Up Trusted CA-Signed TLS Server Certificate

You can set up trusted CA-Signed TLS server certificate to ensure that traffic between clients and desktops is not fraudulent.

Prerequisites

  • Replace the default self-signed TLS server certificate with a trusted CA-signed TLS server certificate. See Replacing the Default Self-Signed TLS Server Certificate. This creates a certificate that has the Friendly Name value vdm.

  • If the client's static content is served by the desktop, set up static content delivery. See Windows - Set Up the Desktop for Omnissa Horizon Web Client.

  • Familiarize yourself with the Windows Certificate Store. See "Configure Omnissa Horizon Connection Server to Use a New TLS Certificate" in the Omnissa Horizon 8 Installation and Upgrade document.

Procedure

  1. In the Windows Certificate Store, navigate to Personal > Certificates.

  2. Double-click the certificate with Friendly Name vdm.

  3. Click the Details tab.

  4. Copy the Thumbprint value.

  5. Start the Windows Registry Editor.

  6. Navigate to the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Omnissa\Horizon\Blast\Config.

  7. Add a new String (REG_SZ) value, SSLHash, to this registry key.

  8. Set the SSLHash value to the Thumbprint value.
