A fast, highly optimized implementation of hash and checksum algorithms: MD2, MD4, MD5, SHA-1, SHA-2 (256, 384, 512), RIPEMD (128, 160, 256, 320), PANAMA, TIGER, CRC-32, CRC-16, CRC-CCITT, ADLER32. The library allows to calculate hashes (message digests), checksums and HMACs for files, memory blocks, strings, blobs, streaming data. It is quick, flexible, easy to use. It supports 3 interfaces: QuickHash 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 QuickHash API), and QuickHash 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 hash, checksum and HMAC calculations to Windows applications quickly and easily.
