STM32H563 DA obk password calculation

I'm trying to understand how the HDPL1 is calculated based on an OBK file.

I have dumped the contents of HDPL1 / 0x0BDF0100 and can see that for a 16 length password, I have 96 bytes written, as follows

0x0BFD0100 to 0x0BFD0120, unknown calc, how is this calculated?

0x0BFD0120 to 0x0BFD0140 SHA-256 of password

0x0BFD0140 to 0x0BFD0160 zeros
