C# 클래스 DS4Windows.Crc32Algorithm

Implements a 32-bit CRC hash algorithm compatible with Zip etc.

Crc32 should only be used for backward compatibility with older file formats and algorithms. It is not secure enough for new applications. If you need to call multiple times for the same data either use the HashAlgorithm interface or remember that the result of one Compute call needs to be ~ (XOR) before being passed in as the seed for the next Compute call.
