To comply with industry or security regulations, you can replace the default TLS certificates that the HTML Access Agent generates with certificates that a Certificate Authority (CA) signs.
When you install the HTML Access Agent on remote desktops, the HTML Access Agent service creates default self-signed certificates. The service presents the default certificates to browsers that use Horizon Client for Chrome.
In the guest operating system on the desktop virtual machine, this service is called the VMware Blast service.
To replace the default certificates with signed certificates that you obtain from a CA, you must import a certificate into the Windows local computer certificate store on each remote desktop. You must also set a registry value that allows the HTML Access Agent to use the new certificate.
If you replace the default HTML Access Agent certificates with CA-signed certificates, configure a unique certificate on each remote desktop. Do not configure a CA-signed certificate on a parent virtual machine or template that you use to create a desktop pool. That approach results in hundreds or thousands of remote desktops that have identical certificates.
