Arpoon Checksum!

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.

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

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

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.

Currently supported hash functions include CRC32, ADLER32, GOST, MD2, MD4, MD5, MD6, SHA1, SHA2, SHA3, RIPEMD, HAVAL, TIGER, WHIRLPOOL and BLAKE2.

MD5summer is an application for Microsoft Windows 9x, NT, ME, 2000 and XP which generates and verifies md5 checksums. Its output file is compatible with the output of the Linux GNU MD5Sum and it will also read Linux generated files. MD5summer is written in Borland Delphi 7. Source is available from the download page.

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.

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.

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. »

WinMD5 is a freeware for Windows to allow user to calculate MD5 hash or checksum for files, and verify a download.

This software allows to generate MD (Message Digest) and SHA hashes from a file or files or files in a directory. Checksum is an value calculated from a content of file by special algorithm. You can also verify the file integrity of the downloaded document or program. File Checksum Utility is very easy to use. From the graphical user interface, choose the file from your computer storage. The tool calculate and display checksum values.
