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

HashTools is an application that calculates hashes for given files. It can calculate CRC32, MD5, SHA1, SHA256, SHA384 and SHA512 hashes, and generate an SFV file for your files if needed. HashTools can also add itself to the Windows Explorer context menu for easy. Just select a file to generate a hash for, click on the button for the type of hash to generate and watch the result magically appear. Once a hash is generated you can copy it to the clipboard, or automatically compare hashes to make sure your file is intact. »

MultiHasher is a freeware file hash calculator. No Spyware! No Adware! No Viruses! 100% Freeware! Clean & simple.

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.

RHash (Recursive Hasher) is a console utility for computing and verifying hash sums of files. It supports CRC32, MD4, MD5, SHA1, SHA256, SHA512, Tiger, DC++ TTH, BitTorrent BTIH, ED2K, AICH, GOST R 34.11-94, RIPEMD-160, HAS-160, EDON-R 256/512, Whirlpool and Snefru-128/256 algorithms. Hash sums are used to ensure and verify integrity of large volumes of data for a long-term storing or transferring.

A fast and easy-to-use calculator that allows to compute message digests, checksums and HMACs for files, as well as for text and hex strings. It offers a choice of 13 of the most popular hash and checksum algorithms for calculations.

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.

Computes the MD5, SHA-1, SHA-256, Tiger, or Whirlpool message digest for any number of files while optionally recursively digging through the directory structure. Can also match input files against lists of known hashes in a variety of formats.

A program to verify and write checksumfiles.It supports SFV and MD5, even some exotic MD5 file types.Very easy to use, with a wizard interface.

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.

MD5 File Hasher allows you to quick and easy determine MD5 checksums of files of arbitrary size.
