| D | crc32.txt | 1 A brief CRC tutorial.
3 A CRC is a long-division remainder. You add the CRC to the message,
4 and the whole thing (message+CRC) is a multiple of the given
5 CRC polynomial. To check the CRC, you can either check that the
6 CRC matches the recomputed value, *or* you can check that the
7 remainder computed on the message+CRC is 0. This latter approach
9 protocols put the end-of-frame flag after the CRC.
18 To produce a 32-bit CRC, the divisor is actually a 33-bit CRC polynomial.
20 CRC is written in hex with the most significant bit omitted. (If you're
23 Note that a CRC is computed over a string of *bits*, so you have
