With the patch below the full 12 bytes of the MCU ID is now taken into account, instead of only the last 4 bytes. Note: HW5 only. Does not introduce any changes for HW 1-4.
To retest and reopen in case the XOR method would not suffice.

New test release available at:
Here a sha256 hash sum is calculated instead of a xor, making change more leveled over all available bytes, instead of a single one.
Test scenario:
User reported, that some of his devices have the same serial number. This could come from GD32 MCU's not behaving according to the STM32 specification, having the same value in the serial number RO register.
Firmware: latest Hardware: GD32-based, probably latest GnuPG: 2.2.27
