authorities right click the venafi certificate and select export > pkcs12 select the export selected option, specify a unique name for the export file, and select \[ next ] enter a file password of your choice and select \[ next ] select \[ finish ] to initiate the export move both the venafi certificate and the root ca certificate that you exported in the export the root ca certificate section to the computer that runs the venafi tpp instance a later section shows you how to configure and use them for tls communication with the {{k3}}
