Add checksum calculations to your Windows apps quickly and easily. Features: Implementation of the most popular checksum algorithms: CRC32(Cyclic Redundancy Check 32), CRC16, CRC16C (CRC-CCITT). It allows Windows developers to calculate in their applications checksums for memory blocks, strings, blobs, streaming data and single files; Fast, flexible and extremely easy to use.

Supports 3 interfaces: FastCRC API (FastCRC API can be used as is, or it can be used to create wrappers for other languages that can use DLLs), C++ Interface (wrapper classes to FastCRC API) and FastCRC Type Library (includes all declarations for accessing FastCRC Library functionality from different programming languages, which have the possibility to reference a .TLB, such as VB 5.0, VB 6.0, VBA, etc.), supports static linking(LIB) and dynamic linking (DLL) (like MFC), no external dependencies such as MFC DLLs, COM/DCOM, or other resources, or components, and excellent documentation with examples in C/C++ and Visual Basic.
