Sets the value of the CommunicationEncryptionKey property required to communicate with the License Server and call any of the QLM Application API.
The communicationEncryptionKey is defined in the web.config file of your License Server. If your QLM Management Console is properly configured to connect to your License Server, you can also locate your communicationEncryptionKey from Manage Keys / Sites / Encryption Keys.
Before calling any QLM Application API that communicates with the License Server, you need to set the CommunicationEncryptionKey property. Failure to do so will typically result in an error such as "Failed to decrypt data".
