Can a customer generate an encrypted file (.ekp) when using the Lite version of Quartus or with a 60-day temporary license that I generate for them?

Hi,

No, You can not.

To generate encrypted file, you need to request for encryption feature license for Lite edition.

Please go to Intel FPGA Self Service License Center (https://fpgasupport.intel.com/Licensing/license/index.html) and the submit Contact Customer Service form (https://fpgasupport.intel.com/Licensing/license/contact.html) to request encryption feature license. In the Contact Customer Service form you need to provide your host id, NIC, number of licenses whether fixed or floating type.

please refer the below old thread for more details,
