Hi Greg. I would at least flip one bit at a time on the first byte of your data to see if the transformation is bitwise.
I'm actually making good progress on this -- it turns out there *is* a way of deducing the polynomial by looking at the effect of single-bit flips. It's actually quite simple, with no brute-force searching needed at all. Things get a bit tricky when you don't quite know all of the data that goes into the CRC, though, which seems to be the case here... I'm writing up an essay on my experiences. I'll post a link when it's finished. -- Greg -- http://mail.python.org/mailman/listinfo/python-list
