HashCheck Shell Extension!

[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.

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. »

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.

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

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.
