CRC-32B

A cyclic redundancy check (CRC) is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to digital data.
CRC32b is an implementation of the consistency algorithm, whereas CRC32 is the frame check sequence.
They only differ in their implementation details and historical uses. One works with streams, the other with frames. For the large majority of cases, this can be assumed to be equivalent in performance.
