New Panasonic Decrypter Hash?

[Maxpower3]

Do you have any info on the new way to decrypt the password.

The Xor key only works on some older models.

If I compare different bios,
I notice that it changes only one byte every 2 bytes. (see screen)

I think that the key is not false but the way of decrypting has to change.

Otherwise what interest to find the Xor key identical or almost,
if it was a hash, it would not need to be presented anymore?



if it can help for research

It is not only with newer panasonics but some other laptops aswell. You can still XOR decrypt using the same XOR key but what you get as a result is a 192 bit encrypted key which needs to be decrypted aswell. Once I saw that, I stopped trying because laptops with such encryption have been easily opened up so I just used a programmer to delete the passwords.

New Panasonic algorythm looks like this :
Password -> SHA1 -> XOR = hash

There are several different algorithms. Not possible to decrypt password. You are wasting your time.

Re:bios password?

I have a CF-53 mk3, here in the company with the bios blocked. I can only unlock by reading the eeprom?
