AVR-EAX-AES-bootloader

Bootloader for AVR microcontrollers featuring EAX mode encryption (AES underlying) in 1024 bytes

Usage:

  • Create unique key file using key_creator
  • Attach bootloader project to your own
  • Change all the settings as desired
  • Replace key_const.asm with the newly generated one
  • Upload bootloader to your device
  • Encrypt new firmware (with no bootloader) with key_creator using the same key file
  • Write your own uploader or use the provided one to upload new firmware to the bootloader, the protocol is simple

Remember: if you ever lose key_const for the device, you will be unable to upload patches to that device! There is no way to do it! Keep your key files in a safe place.
