Fast, highly optimized implementation of popular CRC algorithms

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. FastCRC Library is easy to use, quick, flexible.

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.

Here are some key features of "FastCRC Library":

Support of:
· 3 checksum algorithms: CRC16, CRC16C (CRC-CCITT), CRC32.

Support of 3 interfaces:
· FastCRC API (The FastCRC API can be used as is, or it can be used to create wrappers for other languages that use DLLs).
· C++ Interface (C++ wrapper classes to FastCRC API).
· FastCRC Type Library (Includes all declarations for accessing the FastCRC Library from different programming languages which have the possibility to reference a Type Library, such as VB 5.0, VB 6.0, VBA, etc.)

Support for:
· Static Linking
· Dynamic Linking
· No external dependencies such as MFC DLLs, COM/DCOM or other resources.
· Excellent documentation (MFC-style help).
