[Solved] CRC Algorithm

[Firestryke31]

Hey all, I've looked (somewhat briefly, admittedly) for a page describing a CRC algorithm (specifically, I need "CCITT32 CRC"). Unfortunately, everything I found was either code (which I don't want to deal with licensing crap), over my head, or 404. I was wondering if anyone could point me to a page that described the algorithm in a way that a college CSCI freshman might understand. Thank you for your help.

Wikipedia has a pretty simple explanation of how to do CRCs

So is CCITT32 just the regular old CRC32 algorithm? I think my confusion arises mostly from the many different names for the algorithms.

All 32bit CRC algorithms are identical. The only difference is the "polynomial" used to generate the sums. If you do a google search on CCITT32, then all you need to do is check the polynomial against the CRC32 page in our wiki (0x04C11DB7) -- if it matches, then it is just regular old CRC32.

Oh, okay. Well, in that case I'm good to go. Thank you both for your help!
