Main > Software Development > Components & libraries > FastCRC Library

  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.

Key features of FastCRC Library:

• 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 from different programming languages which have the possibility to reference a Type Library, such as VB 5.0, VB 6.0, VBA, etc.);

• Supports static linking and dynamic linking (like MFC);

• No external dependencies such as MFC DLLs, COM/DCOM or other resources;

• Excellent documentation with examples in C/C++ and Visual Basic.
