I have the algorithms for Ford and Smart. My email is {removed by admin}.

Or, even better, share the algorithm publicly for the benefit of all.

Hello, I'm interested in algorithms for Ford!

Send me your contact, Please!

I have a ECU that gives an eight byte seed
I have 3 pairs of seed and keys
SEED: A2 AF 8E 55 C9 0D CC 7B / KEY: 7F 5D 4A 62 86 C7 B4 C9
SEED: 9E A7 6B CD B0 B3 DE 05 / KEY: DE FB C3 D7 32 26 42 9E
SEED: 1A 5E 0F 7C B2 88 9D BA / KEY: F2 FE 5A AA 72 02 CD 9F
I also heard that its easier to get the algorithm from the binary but i don't have an experience in disassembly.
I can post the binary if it would help
If someone can figure this algorithm out please tell me how you did it since I'm not interested in finding the algorithm i want to learn how to find it
Thanks guys

Hi!

CAN someone send me Smart for two (451) seed key?
Thank you!

Hi I'm new to the forum but have done a fair bit of CAN & OBDII hacking over the years.

I have a Honda 2011 CRZ ECU and am wanting to decode the seed/key challenge.

Here are some captured valid challenge and response byte pairs.

Any ideas on how it is working and generating the response?

Challenge $E3 $C5
Response  $82 $CB

Challenge $79 $71
Response  $04 $35

Challenge $84 $15
Response  $ED $85

Challenge $9B $B6
Response  $6F $C9

Challenge $C7 $B0
Response  $1A $DD

Challenge $AB $19
Response  $9A $69


I want to PM a couple of members including 'diagtoola' but I am unable to use PM (new member) so perhaps the admin can set that for me . Thanks.

If you Google my name username in reverse in relation to Honda IMA stuff you will find me online to message me directly.
