| H A D | crc32.rst | 2 brief tutorial on CRC computation
5 A CRC is a long-division remainder. You add the CRC to the message,
6 and the whole thing (message+CRC) is a multiple of the given
7 CRC polynomial. To check the CRC, you can either check that the
8 CRC matches the recomputed value, *or* you can check that the
9 remainder computed on the message+CRC is 0. This latter approach
11 protocols put the end-of-frame flag after the CRC.
21 To produce a 32-bit CRC, the divisor is actually a 33-bit CRC polynomial.
23 CRC is written in hex with the most significant bit omitted. (If you're
26 Note that a CRC is computed over a string of *bits*, so you have
