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.

Indigo Rose's Visual Patch provides software developers with a comprehensive solution for creating secure full-history software update patches. Designed for use on all 32-bit Windows platforms, these compact, self-installing patch files can be distributed on diskette or CD-ROM or sent via email, web or LAN.
Unlike setup programs, which contain all of the files needed to run an application, patches created with Visual Patch contain only the files that changed from the previous releases. Since users must have an eligible previous version of an application installed in order to make use of a patch, developers are free to make patches available to everyone - on a public web page, for instance - without permitting unauthorized use of their software.
Visual Patch's point-and-click integrated development environment visually indicates the differences among product releases and automatically builds only those changes into the patch. Developers will spend less time preparing updates for distribution and more time working on their software product.
Features of Visual Patch include full-history patching to bring all in-field versions up to date using a single self-extracting executable, a familiar "wizard" style runtime interface, customizable dialogs, use of key files and CRC-32 checks to ensure accuracy, international language support, extensive system editors including registry and shortcut icons, conditions, variables and much more.
Indigo Rose provides software developers with tools to manage the complete software deployment life cycle. From multimedia application and CD-ROM front-end creation using AutoPlay Media Studio to automated Internet-based software installation, updating and patching with Setup Factory, TrueUpdate and Visual Patch, Indigo Rose offers an array of easy to use solutions. Privately held, Indigo Rose has been developing innovative software development tools since 1991 that are used by thousands of corporate, government and ISV developers.

CDCheck is utility for prevention, detection and recovery of damaged files with emphasis on error detection. It can check each your CD/DVD (or any other media) and indicate which files are corrupted. CDCheck reporting features tell you exactly where the problems are. Files on CDs, zip drives, USB keys etc. can get damaged in a number of ways, so the program helps you determine whether your data is safe before it's too late. The program also provides extremly fast binary compare for effectively checking that file transfers (burning, copying...) were accomplished successfully and alerts you of differences. Besides that CDCheck supports creation and checking of MD5, CRC-32, SHA... hashes in SFV, MD5 and CRC file formats. This provides means to check backups for possible loss of information or verify file transfers where comparing is not possible (transfer over mail etc.). The program can be used with all local or removable media (CDs, DVDs, disk drives, floppy disks, ZIP drives, USB keys...) visible by the operating system (Windows Explorer) and also with audio CDs. In addition CDCheck also gives detailed information (manufacturer, type, capacity...) about inserted CD or DVD media.

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
The CRC is a "digital fingerprint" of a file, With CRC32 you can "melt down" a huge 20 MB (or even much bigger) file to have a small, handy reference to it, a single 32-bit number like 7d9c42fb (hexadecimal notation) which would unambiguously reflect the entire contents of this huge file. Now if some changes to this file happened, no matter how small, maybe only a single wrong bit somewhere in the middle, a new CRC-32 calculation would yield a completely different reference number (say 3faa83bd). So there?d be no doubt about it - this is not the same file anymore. On the other hand if the reference number was still the same (7d9c42fb) you might be sure that the file hasn?t changed.
The algorithm of CRC32 is exactly the same as that internally used by PKZIP and WinZip; i.e. the CRCs calculated by PKZIP and CRC32 are identical. That?s another fine thing about CRC32 - it calculates compatible, widely used 32-bit checksums, not just any numbers. You can use the 'pkunzip.exe -vt filename.zip' command to see that PKZIP?s CRC-32 values of files stored inside the filename.zip are identical to that calculated by CRC32 for these files.
Though you can use CRC32 to calculate 32-bit checksums of any file the real strength and usefulness of CRC32 is in comparing Wave Sound Files to see if their non-silent music parts are identical. In particular CRC32 may come in handy when comparing two different extractions of a CD Digital Audio track to ensure that the performed digital copy is perfect.

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.
NEW in v1.11 - can create sfv files and automatically scan folders for .sfv files and check them

The Registry Drill is the most in-depth Registry utility available today. It goes through the Registry character by character searching for any possible errors. The Drill has two main components, the Quick Drill which quickly searches the Registry for 15 different possible types of errors that other Registry cleaners do not. The Deep Drill goes through the entire Registry slowly and carefully, looking for more than 50 different kinds of errors.
