TIdHashCRC32
Implements methods used to calculate a 32-bit CRC value for data in an input stream.

TIdHashCRC32 = class(TIdHash32)
Description
TIdHashCRC32 is a TIdHash32 descendant that implements methods used to calculate a 32-bit Cyclic Redundnacy Check (CRC) value for data in an input stream. TIdHashCRC32 uses a pre-computed 1024-byte lookup table for faster calculation of CRC values.
