CRC32 Static Library for Microsoft VC++ was produced to make your CRC checking operations quick & easy to implement seamlessly without the need for an external DLL
Fast, highly optimized implementation of popular checksum algorithms: CRC32, CRC16, CRC16C (CRC-CCITT). The library allows to calculate checksums for files, memory blocks, strings, streaming data.
CRC .NET control is the checksum library for .NET developers.The library, especially written on .NET framework, provides exact and fast calculations of checksums. The library has an easy to use interface and fast and reliable infrastructure.
Simple and easy to use file hash value calculator embedded into Windows properties pages and compatible with febooti fileTweak module integration. Supports CRC32, MD5, SHA-1 and other most common hash algorithms.

CRC32 COM Component
$29.95 - Traction Software
CRC32 COM Component is for ASP, .NET, Cold Fusion, VB, VC++ and other languages.
The com component will quickly generate a CRC32 checksum from files or a text string in hex or numeric as the official polynomial used by CRC-32 in PKZip, WinZip and Ethernet.

QuickCRC MacOSX
$295 - Excel Software
QuickCRC is a tool for responsibility driven design of object-oriented software using CRC cards. CRC cards are used to discover and document classes, responsibilities, attributes and collaborations between classes. Design scenarios can be identified and simulated. Complex designs can be partitioned into multiple diagrams with easy navigation through a contents view. The inheritance graph automatically shows the class structure of the evolving design. The user can assign the attribute access of each card responsibility and the tool presents an attribute access graph.

QuickHash Library
$149.95 - SlavaSoft Inc.
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.

SFV Checker
$8.95 - Traction Software
SFV Checker uses CRC-32 technology to check each file and notifies you of any potentially bad, corrupt, incorrect size or missing files to save you hours of downloading only to find you have 1 file missing or the last file has a CRC checksum error.
The CRC value comparison is done by using a standard SFV file. If an SFV file is not available, you can drag and drop the file into the list view to produce the calculated CRC value. An informative report log is generated after file scanning that provides a list of missing and inconsistent files, as well as, a summary for the archive.
SFV Checker can also concatenate files in the list and rename multi archives on the fly, e.g. Correct file naming for .001, .002, .003 files into .rar, .r00, r01 files.
SFV Checker supports RAR, ARJ, ACE and ALL other Binary/Text file types.

Fsum Frontend
$0 -
Fsum Frontend is a free and easy-to-use tool that allows to compute message digests, checksums and HMACs for files and text strings. It supports drag-and-drop and you can handle multiple files at once. The checksum generated can be used to verify the integrity of the files.
It supports 58 algorithms: adler32, cksum, crc8, crc16, crc16 x25, crc24, crc32, crc32 bzip2, crc32 mpeg2, crc64, edonley/emule, elf32, gost, has160, haval (128, 160, 192, 224, 256 bits) (3, 4, 5 passes), md2, md4, md5, panama, ripemd128, ripemd160, ripemd256, ripemd320, sha0, sha1, sha224, sha256, sha384, sha512, sum8, sum16, sum24, sum32, sum64, sumbsd, sumsyv, tiger128, tiger160, tiger192, tiger2, whirlpool0, whirlpool1, whirlpool2, xor8.
It also supports MD5 and SFV file creation and verification.
Features:
- Calculate the checksums, message digest and HMAC of files and text strings.
- Verify files using a SFV or MD5 file and notify you if a file is corrupted or missing.
- Create a checksums file.
- Rename a file with a checksum.
