  Why use MD5 anymore Fed Requires SHA2 based algorithms....  cracked

  Cracked, Some scenarios don't care about the possibility of someone introducing a collision; for example when hashing local files to quickly identify duplicates. Similarly, some communication protocols require MD5; for example, HTTP's digest access authentication: en.wikipedia.org/.../Digest_access_authentication I'm all for using the strongest algorithm possible - it's just that sometimes it's not necessary - or possible. :)

  Your CRC32 class has a static constructor with the comment: "Table values must be computed; not possible to remove the static constructor." Of course it is - just create a private static function to build the table and assign it inline: private static readonly uint[] _crc32Table = BuildTable(); private static uint[] BuildTable() {    uint[] result = new uint[256];    ...    return result; }
