In attachment you have 2 series of data: SEED (S1-S4) and KEY (K1-K4). Both SEED and KEY are 32-bit long, but actually they consist of two 16-bit numbers, so we can consider it as 16-bit. The task is to determine a formula or algorithm, which converts SEED into KEY (hash-table of all combinations is not an option). If you see at the binary representation (...BIN columns in attachment) - obviously there exists a relation between SEED and KEY. Some bit shifting, swapping, negating, multiplication should be enough to calculate the KEY.

Hi, the working formulas for K3 and K4 are similar and contain about 20 arithmetic and bitwise operations. K1 and K2 are also similar containing about 30 operations. There are also 5 constants, repeatedly used by the formulas. All 4 formulas were carefully verified to be correct for all rows in the table.

Hello, I have a lot of seed key algorithms. Please send me more details about this algorithm: - From what controller is it? Car model, year and so on. - Which application did you take the log from? Kind regards, dragomir_goranov
