No, I don't know
Why would it matter?
It's encrypted and even if encryption of the sector itself is also AES256 to encrypt/decrypt the sector with password, the password should be hashed (and possibly salted). I believe the hash algorithm wasn't released into public documents

Do you know how AES works ?

You have the great opportunity to be the n-th to try RE the mechanism of encryption / decryption behind SmartWare.
(If it was so simple, there would be a lot of problems)

This has nothing to do with knowing AES, it is mainly about how/where those bits are stored and in order to know this I guess the datasheet of this chip is needed.

Am I the only one who senses double standards here
Anyway from what I see you still have no clue how encryption works IMHO. I just completely waisted my time trying to explain the theory to you. Pity.
