WebCRC-8, CRC-16, and CRC-32 have similar computation algorithms. To compute an n-bit binary CRC, pad the input by n bits and line it with the n-bit divisor based on the chosen polynomial. Then iteratively divide the data by the n-bit divisor by positioning the divisor below the first 1 in the input. This is effectively bitwise XOR-ing and the ...
