RapidCRC!

The HashCheck Shell Extension makes it easy for anyone to calculate and verify checksums and hashes from Windows Explorer. In addition to integrating file checksumming functionality into Windows, HashCheck can also create and verify SFV files (and other forms of checksum files, such as .md5 files). It is fast and efficient, with a very light disk and memory footprint, and it is open-source.

[Hashtab is free for personal use for Windows, NOT for Mac: it can be bought for $1.99 from the Mac App Store.]

HashMyFiles is small utility that allows you to calculate the MD5 and SHA1 hashes of one or more files in your system.

RapidCRC is an open source CRC/MD5/SHA hashing program.

Md5Checker is a free, faster, lightweight and easy-to-use tool to manage, calculate and verify MD5 checksum of multiple files/folders

QuickSFV integrates into the Windows Explorer shell and makes it very easy to verify files. Just double-click on the SFV file and QuickSFV does the rest. QuickSFV also understands several other file verification formats including CRC, CSV, and CKZ. For even quicker verification of SFV files, QuickSFV remembers which files have been previously verified and will skip them in future checks. You can always tell QuickSFV to go back and verify all files again just to be sure.

GUI frontend for fsum – a hash calculator supporting a ton of algorithms.

CHK is an advanced checksum utility — a simple application designed to help you verify the integrity of your files, find duplicates and much more!Main Features

checksum is an easy-to-use, no-nonsense BLAKE2, SHA1 & MD5 hashing program for Windows, capable of creating & verifying hashes of files and folders, even whole drives, with just one or two clicks. It is robust, lightning fast, intuitive, and completely customizable. It comes with an installer that adds hashing options to your Explorer menus, or alternatively, can be simply unzipped for portable operation. Or both.

FileVerifier++ is a Windows application for verifying the integrity of files. FileVerifier supports various algorithms by means of dynamically loadable hash libraries. It uses the Windows API and doesn't have any dependencies other than what comes with Windows (WinFVC excluded).

MD5 & SHA Checksum Utility is a tool that allows you to generate CRC32, MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes of single or multiple files. You can also verify hashes with the matching file to ensure the file integrity is correct.

cfv is a utility to both test and create .sfv, .csv, .crc, .md5(sfv-like), md5sum, bsd md5, sha1sum, and .torrent files. These files are commonly used to ensure the correct retrieval or storage of data.

This tool will generate hash strings to validate directories and files, in the same vein as hashdeep or fciv. I wrote it after giving up trying to find a decent tool to validate my backups. Although many tools like the two previously mentioned will generate hash files for directory trees, none seem to support maintaining those files as the trees change over time. Hash has many option to keeps the hash files, and the files the hashes were generated from, in sync.

CDCheck can check each of your CDs and DVDs and indicate which files are corrupted. It also provides a comparison option that lets you select a reference directory and compare the files on disk (or other media) with files on the CD or vice versa. Additional features include creation of CRC files, file recovery, detailed error reporting and more. Does not work with Audio Cds.

A file integrity verification tool:Use it to make sure files copied to CD-ROM are bit-perfect copies,Use it to make sure backups copied from one drive to another are just right,Use it to make sure files haven’t been changed or damaged over time.Multi-threaded, so your extra CPU cores get used when scanning multiple files and work gets done faster.Happy with Unicode file names, so it doesn’t fail when you’re using it on files named in Japanese, Hebrew, Chinese, or any other language.Supports multiple checksum routines (hashes), like MD5, SHA1, CRC32, RIPEMD and others.Supports recursive directory scanning.Supports Very Big Files — If it’s on your hard drive, ExactFile can handle it.Does everything popular file summer utilities do, like fsum, md5sum, sha1sum, sfv, etc, but better!Compatible with popular file checksum digest formats.For Windows 2000, XP, Vista, and 7.GUI. Easy to use to get checksums for individual files, create checksum digests, and test checksum digests. Does not require the console version or any external DLLs. »
