Need PIN from dump! Please?

[kiszka]

while i'm waiting for my transponders i started to investigate the Pin code decryption of the Alfa/Bosch 60653687 code2 93c56 16 bits file - i located the crypted pin bytes on 67-69 , using Effi or Zedbull i can generate calculated pincodes by changing these bytes in the 93c56 file , for example 00 00 00 gives pin code B8C73 (would translate to pin 28373) and FF FF FF gives pin code 4738C which translates to pin 47383.
My own pincode would be decoded from bytes 29 5F 5C which would give pin 27691.
the first two file bytes generate only the first pin number, the second and third file bytes generate pin number 2 and 3 and the last two file bytes generate the last two pin numbers.
I already tried many random combinations but i did not yet find the algo yet , i see some odd/even and xor relationship but with enough patience it should be possible to extract the logic behind the pin calculation.
Maybe there are members with a good eye for logic interaction between the numbers, i'm not so good at it but i will give it a try, maybe someone can beat me figuring it out....

I think it's a waste of time because you already have the pin
even if someone decrypts it for you
You still have to write data to the key
so your work does not make sense, unless you write your own program, keep working

yes you're probably right but i always want to understand how things work, just picking a ready solution is not very satifying....
So i will give it a try, will post my findings if i found the pin algo !

It still play with Effi and find algorithm

[yellowstilo]

you mean you know how the pin is decrypted from the file ?

no, i don't know and see no point, waste of time

i did try to login with pincode with 2 different files and programmed transponders but still no joy, the Examiner Smart does not accept the pincodes....
To be continued....

i finally managed to login with the pincode using the Examiner Smart HD tester - i used a 93c56 file from DK with PIN 55292 but i had to flip the bytes of the entire file before the tester accepted it - in the "normal" way it produced a lot of unreadable garbage info .
It was also strange to see the pincode did not change although the bytes were moved to other locations so i guess it will be some sum calculation of a fixed part of the file where the byte order is not important ....
