                Have you got a XOR key ? Cant calculate without key. But why you need to calculate , just fill all of this string in dump with 00 (zeroes).
                Try HERE (you`ll need a XOR Key), but in almost all cases password is HASHED.

                          There is nothing funny

                          just use her brain and the info on the page.

                          Everything is indicated here.

                          You have all the links to find and understand the principle of operation.

                          Too easy to share my files that I took hours to create.

                          They are provided in another tool which is not yet available.

                          If you want to understand, search a little.
                          Otherwise just ask for your password

                          Just Google search for “Recovering the BIOS password from a Panasonic CF-U1 mk2”, you’ll find a GitHub post with details.

                            Why you need to calculate is because otherwise you would need to remove the screen to do that. I doubt anybody would want to do that on a surface if decrypting is this easy.

                                  Hello all. I recently acquired a small army of surfaces and they're functional, but they have a bios password. I've been trying to figure out how to do it myself since there's so many of them, but I'm stuck at the actual decrypting part. I followed the guide from the Panasonic bios recovery on github, but I'm unsure of where the author got the second hex string from. Thanks for any and all help and I have attached a bios file from one of the devices.

                                  Code:
                                  00000000000000000000000000000000
                                        00000000000000000000000000000000
                                        00000000000000001A93F22641BA2C4D

                                    If you have a bunch of these, there's a probability that the supervisor password may be the same in all of them, for this one it is (pswrd is case-sensitive):
                                    password = ADP@LSC

                                    There's a GitHub post with the information you are looking for, it's related with a Panasonic ToughBook laptop, you need the XOR key and all you have to do is XOR the "password-block" (you extracted from AMITSEVAR) versus the "xor-key", you will get the result which will be in Hexadecimal numbers (0-9, A-F), then just do the HEX conversion to ASCII to get the password.

                                        Discard the 00h NULL bytes and this translates to:
                                        password = rj45b105

                                        ...just XOR the contents of AMITSESetup variable block contents versus the XOR-key.
