However, sometimes you must compute a CRC in software, for example in a C or C++ program that will run CRC32 is a popular checksum algorithm used to detect data corruption. Multiple variants of the algorithm exist which have similar mathematical properties. The most common variant of the CRC32 checksum, sometimes called CRC-32b, is based on the following generator polynomial: g(x) = x 32 + x 26 + x 23 + x 22 + x 16 + x 12 + x 11 + x 10 + x 8 + x 7 + x 5 + x 4 + x 2 + x + 1.

Note that the crc32 algorithm includes a final XOR step. If incremental processing is desired then this must be undone before using the output of the algorithm as the seed for further processing. A simpler alternative is to use the PROGRAMMING INTERFACE which is intended for this mode of operation. public class CRC32 extends Object implements Checksum A class that can be used to compute the CRC-32 of a data stream. Passing a null argument to a method in this class will cause a NullPointerException to be thrown. 2017-02-12 · But if you ever are in a situation that you need to calculate a checksum using the CRC32 algorithm, I got you covered with this small function.

Simple file verification(SFV) is a file format for storing CRC32 checksums of files to verify the integrity of files.

What is Cyclic Redundancy Check and CRC-32? A cyclic redundancy check (CRC) is an error-detecting code used to detect data corruption.

The changes were added before the initial commit, but try comparing the new CMakeLists.txt and the old one (which doesn't mention SSE at all). The best option is probably Intel's zlib fork with PCLMULQDQ support described in this paper.
