Hi Siva,
Thanks for the response.
Please note that it would not be possible without communication with the master key. This is per product design.
You may take the C2V file from customer and generate 'format' v2c using Sentinel hasp server. Applying this format v2c file on customer's machine will format the Sentinel Hasp HL key.
Feel free to get back to us.
Regards,
Gaurav Bhanot
