A highly optimized implementation of the most popular CRC algorithms.

The library allows Windows developers to perform checksum calculations for memory blocks, strings, blobs, streaming data and files in their applications.

FastCRC Library was designed to be fast, flexible and extremely easy to use.

FastCRC Library Main Features:

• 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.
