you missed the point which was there is no correct "one". there are lots and lots of correct values that can give you the same exact results and there is no way to know which one was the one used.

since you claim you've received a solution through telegram, i'm wondering whether i am missing something or your solution is not working. if it does could you tell me what my a and b are with the following w1 and w2? it should be trivial if you have a working solution.

here is SHA256 hash of ab (a concatenated with b) as string so that you can know i am not going to change a and b
