A fast, highly optimized implementation of popular
checksum algorithms: CRC32, CRC16, CRC16C (CRC-CCITT).
The library allows to calculate checksums for files,
memory blocks, strings, blobs, streaming data. It is
quick, flexible, easy to use. It supports 3
interfaces: FastCRC API (the API can be used as is, or
it can be used to create wrappers for languages that
can use DLL or LIB), C++ Interface (C++ wrapper
classes to FastCRC API), and FastCRC Type Library
(includes all declarations for accessing the
functionality from programming languages that can
reference a .TLB, such as VB 5.0, VB 6.0, VBA, etc).
It allows static/dynamic linking. It has no external
dependencies such as MFC DLLs, COM/DCOM or other
component. The help file has C, C++ and Visual Basic
examples showing how to add checksum calculations to
Windows applications quickly and easily.
