2.4.3 MsoCrc32Compute


The purpose of this algorithm is to calculate a cyclic redundancy check (CRC) checksum. Given a data stream, this function computes a 32-bit checksum using the polynomial x32+x7+x5+x3+x2+x+1. The algorithm uses big-endian bit ordering in a byte (most significant bit first). Normal representation for a polynomial is xAF.
