Chaos MD5 is a free MD5 generator for Windows, input any file into the program and it will generate an MD5 checksum unique signature for that file which can be used for file identification or integrity checks. Chaos MD5 does not require installation, simply copy it to a hard drive or USB device to run.

HashOnClick is a program to calculate the CRC-32, MD5, or SHA-1 hash value for a file, it is implemented as a shell extension in the Windows Explorer right-click menu. Many web sites list the MD5 value of a file so that you can check your download to see if the file is the correct size. Some FTP servers let you retrieve the MD5 value of a file (via the XMD5 FTP extension). CRC32 values are used in Zip files, and some FTP servers let you retrieve the CRC32 value of a file (via the XCRC FTP extension).

The famous MD5 algorithm presents an easy and highly secure way of verifying the integrity of files. Software is often accompanied by an MD5 'hash' (or 'checksum') that serves as a unique identifier for the contents of the file - if the file contents change then so does the MD5 hash, making it easy to verify the integrity of files. Single-line text, multi-line text and file contents are all supported inputs. The resulting MD5 hash is displayed in a textbox for easy clipboard copying.

MD5 Checker is a free utility to verify downloads with an MD5 checksum, you can also create your own MD5 checksum if required. Tiny full Windows program to verify MD5 checksums - where an MD5 code is given for a download file, using this software, if the codes match, the download is good.

Mat-MD5 is a free software that allows you to check the MD5 value for each file processed and compare it with other MD5 strings. It will process one or more files and it will add the result value to a list. You can add your MD5 value to compare by typing it or by copying it from an external file, so you can easly compare your values. It is very useful for example, when you download a big file - such as an *.ISO - and you want to check if it is the correct one. You can save your results to an external file; if takes too much time to check for a file you can stop the process when you want.

File Integrity Verification & Encryption (FIVE) is a simple application that has been designed to encrypt/decrypt files (with the AES) and to detect whether files have been modified between 2 uses of FIVE (with SHA1). Ideally FIVE.EXE should be stored on and used from a write-protected medium such as a CD-ROM or floppy disk to prevent unauthorised modifications.

A fast and handy command line utility for file integrity verification. It offers a choice of 13 of the most popular hash and checksum functions for file message digest and checksum calculation. The most common use for FSUM is checking data files for corruption. A message digest or checksum calculation might be performed on data before transferring it from one location to another. Making the same calculation after the transfer and comparing the before and after results, you can determine if the received data is corrupted or not. If the results match, then the received data is likely accurate.

digestIT 2004 is a very simple message digest application that allows you to quickly calculate the MD5 or SHA-1 checksum of any file or multiple files or verify a single file against an MD5 or SHA-1 checksum string.

Simple utility to create checksum files based on the MD5 hash routine. Recursively scans a selected folder and creates the checkfile data which can then be loaded in for testing to determine if the files have changed at all. Great for putting in the root folder of a CD-ROM to make sure the disc isn't defective when it is burned or mass produced.

hkSFV is simply the easiest, most intuitive and automatic way to create or check SFV and MD5 files. If you need to ensure that your data or data you download is error free, this program is for you. An SFV file is a tiny list of files and CRCs, which allow you to check to see if the files you have downloaded are exactly what you are expecting. The CRC algorithm used in .SFV files allows you to see if the file you have has been changed, even a single byte, since the .SFV file was created.

dsSFV is an essential tool for integrity verification of downloaded or copied MP3, AVI, ISO and other files. dsSFV can scan entire folders and create a list of file CRCs in the popular "Simple File Verification" format, or verify an existing SFV list. This can also be used to detect any file tampering by viruses, hackers, crackers, etc. dsSFV is a very small, fast and efficient application designed without VB, MFC, or similar bloatware. Deep integration with the system makes it extremely simple to use. dsSFV offers many unique options, including logging, diagnostics, statistics, built-in SFV editor, as well as flawless processing of SFV files from other systems like UNIX or Mac.
