FROM THIS LINK: HOW TO CREATE THE SECURE BOOT KEY (SBK) from the UID

http://projects.pappkartong.se/a500/

Generating the SBK

To generate the SBK from the UID (assuming UID is a hexadecimal string)

1. Discard any leading 0x in the UID

2. Split the UID into four 4 character strings

3. For each part, take the ascii values and multiply with 100 raised to the position.

e.g. "89AB" => 56*100**3 + 57*100**2 + 65*100**2 + 66*100**0 = 56576566.

4. xor

5. If using a little-endian architecture, swap the byte order

6. Print the key

55520055 => 35:35:35:32:30:30:35:35

Sorry this is so verbose, but I wanted to show all of my steps.

THIS IS WHERE I AM STUCK, any ideas?
