| D | crc32.txt | 5 A CRC is a long-division remainder. You add the CRC to the message,
9 remainder computed on the message+CRC is 0. This latter approach
20 Like all division, the remainder is always smaller than the divisor.
36 and append it to the current remainder. Then you figure out the
37 appropriate multiple of the divisor to subtract to being the remainder
39 and to make the XOR cancel, it's just a copy of bit 32 of the remainder.
43 the polynomial from the remainder and we're back to where we started,
49 multiple = remainder & 0x80000000 ? CRCPOLY : 0;
50 remainder = (remainder << 1 | next_input_bit()) ^ multiple;
53 Notice how, to get at bit 32 of the shifted remainder, we look
