Hi, yes you may encrypt the new design file with the same key. In fact, you can only program the design file encrypted with the same key.

Hi,

Thank you for your reply.

I didn't mean a new design file, but other data that we store on the flash.

During operation, nios read/write data from/to the flash. Is there an option to encrypt this data using the existing mechanism that deals with flash encryption (Design secure feature), or we need to use another encryption block to be in the middle between nios and flash?
