encryption-enabled bootloader
« on: June 13, 2010, 12:48:32 pm »
We have a device with a PIC18F... microcontroller. Our customers should be able to update the
firmware by usb, so we need to provide them with the HEX file.
However, we would like to encrypt the HEX file, so that they cannot decompile it.

Thus, we need a kind-of encryption-enabled bootloader.
Do you have such a product, or any solution to protect our code?

Best regards,
David
