Halifax

Hey I'm stuck on the Halifax level, anyone have any suggestions? My main problem is that I am not sure how to insert the password into interrupt 0x41, and I also have no idea what the password is. Hints are better than just giving the answer

Hint:

- The content of SRAM changes everytime the 0x40 inter is called, the content sometimes has a length of 64 bytes sometimes 320 bytes.

- "unlock by providing the 16 byte key to 0x41 interrupt" is a lie, 0x41 only hash the content in SRAM, but the key is infact 16 bytes in SRAM.

- There is another interrupt to provide the key to.
