 Optimized and fast implementation of Crc32 algorithm in pure .NET.

+*(But if you need, I can add native implementation which is twice faster .NET version with transparent .net wrapper)*
 
 This library is port of [Crc32C.NET](https://crc32c.angeloflogic.com/) by Robert Važan but for Crc32 algorithm. 
 
-If you did not catch the difference, it is *C* (Castagnoli). I recommend to use Crc32C, not usual CRC32, because it is faster (up to 20GB/s) and slightly better in error detection. But if you need exactly Crc32, this library is the best choice.
