alt Hacker NewsLooking in the binary for the polynomial and knowing what the common ones are from experience is an easy way.
Normally, the polynomial is going to be found right next to a loop that is ingesting bytes incrementally.
Looking in the binary for the polynomial and knowing what the common ones are from experience is an easy way.
Normally, the polynomial is going to be found right next to a loop that is ingesting bytes incrementally.
The polynomial is not present in the binary. The table was obfuscated so this approach will not work here (and it's pretty common to do this specifically to stop such a simply look at the bytes in a binary).
