CRC32 Checksum
32-bit cyclic redundancy check, or CRC-32, checksum. See wiki: Cyclic Redundancy Check for information. Polynomials are represented in LSB-first form also known as reversed representation. See wiki: Mathematics of Cyclic Redundancy Checks for information.
IEEE is by far and away the most common CRC-32 polynomial. Used by ethernet (IEEE 802.3), v.42, fddi, gzip, zip, png, ...
IEEE Result:
Castagnoli's polynomial, used in iSCSI. Has better error detection characteristics than IEEE.
