(Optional) Retrieve the public key of the Unwired Server to populate its value in the provisioning file.
During startup, the server verification key is stored in a text file called SUP_HOME\Servers\MessagingServer\ServerVerificationKey.txt . It is created only at messaging service startup, so you must start the messaging service once to generate this file. The file is Base64 encoded, and the contents must be used as the value for the serververificationkey= key.
