I'm looking for assistence to reverse a 28-32bit crc algorithm.

Example:

data checksum

0B202898 A3B85990

0B202871 25F78360

0B202869 09DF6460

I will generate more examples if needed. Its not fully proven the algorithm is crc but it's my best guess. Please note that the checksum is always ending four zero bits (might be an error in the algorithm).

What I'm looking for, is a C/C++ implementation to calculate checksum for given data.
