WebMay 20, 2024 · CRC32 works very well as a hash algorithm. The whole point of a CRC is to hash a stream of bytes with as few collisions as possible. That said, there are a few points to consider: CRC's are not secure. For secure hashing you need a much more computationally expensive algorithm. Different CRC flavors exist with different properties. http://duoduokou.com/algorithm/30793692028354792108.html
