Fsum Frontend is a free and easy-to-use tool that allows to compute message digests, checksums and HMACs for files and text strings. It supports drag-and-drop and you can handle multiple files at once. The checksum generated can be used to verify the integrity of the files.
It also supports SFV, MD5, SHA1/SHA2 files creation and verification.
Base32 encoding (Request 1911022) and Bubble Babble encoding. Option to generate a checksum file in another location (Request 1912905). Generate hash files for strings (Request 1921681). Generate hash files for each file of the user input (Request 1921682). Bug fixed: fix the error "4invalid UTF-8 sequence" that stop the verification process (Bug 1934374).
RapidCRC is a tool for windows for checking and creating CRC32 and MD5 checksums (.sfv/.md5 files). Goal is to use the fastest available (assembly) implementations for this task. Specialty: direct support for CRC32 checksums stored in filenames.

What is an .SFV? -- 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.
What is an .MD5? -- In a sense, .MD5 did not exist until now, as md5sum is a popular Unix format similar to .SFV and Unix does not use file extensions the way Windows based systems do. .MD5 uses the md5 algorithm to compute its checksums, rather than the crc32 method used by .SFV. The md5 algorithm is almost as fast as crc32, but it is much more accurate at detecting changes in files.
If you need to ensure that your data or data you download is error free, this program is for you.
If you've got an .SFV or .MD5 file, this is the program for you. If you'd like to create an .SFV or .MD5 file, this is the program for you.
Here are some key features of "hkSFV":

(leaves no trace in the registry, even goes one step further than most programs and restores previous file associations when you remove it) · One-click creation and checking of .SFV's and .MD5's · Flawless & smooth upgrading to new versions (simply install the new version) · Automatic association with .SFV files, and an option to fix file association when other programs steal it · Handles .SFV and .MD5 files from any other program invisibly (including files created on *nix) · Database / cache of previously checked files · Batch .SFV and .MD5 checking! - queue up and check many .SFV's and .MD5's in one pass, specify a directory and check all the .SFV's and .MD5's in that directory (including subdirectories, if you want) · Automatically find renamed files while checking .SFV or .MD5 files · Enqueue .SFV's or .MD5's during file verification · Recursive directory support during creation and verification · Supports creation of .bad and .missing files, or deleting failed files · Drag and drop .SFV or .MD5 file or directory to create/check .SFV or .MD5 · Explorer Info Tooltip
A free tool that allows you to open and create SFV files, verifying them and determining if you have corrupt parts
FlashSFV is a small, simple, easy-to-use and free tool that allows you to open and create SFV files, verifying them and determining if you have corrupt parts, in addition to which parts are bad or missing.
What is SFV? - Simple file verification (SFV) is a file format for storing checksums of files in order to verify the integrity of files. SFV can be used to detect random corruptions in a file, but should not be used for checking authenticity.
What formats are supported? FlashSFV supports CRC32 and MD5.
A software application to manage, compute, and verify your files' MD5s.
Did your computer ever infected by some new Viruses, Trojans or other threats even you had installed an Anti-Virus program? Did you have no idea which installation files are "good" and which are "bad" when you rebuild your system after a big Viruses explosion? Did you know even the files are disinfected, they are still permanently modified? (For example, the virus codes are removed, but blanks are left. They probably can't be executed properly after disinfected.)
Why should I use Md5Checker? · To verify the integrity of downloaded files: With Md5Checker, user can calculate MD5 checksum of downloaded files and compare them with provided when downloading via HTTP, FTP, P2P, etc. · To detect unknown viruses: Only-for-existing-viruses DB based anti-virus programs can rarely detect all emerged new (i.e. not in the DB) viruses in time. As a supplement, Md5Checker checks whether files are original. By that user can detect any change of file including virus infection. · To make sure that the installation files are secure: System will be re-infected by viruses time and again while reinstalling software if the installation file had been infected. To avoid this, Md5Checker user can calculate and save the MD5 checksum right after downloaded/copied installation files, i.e. make sure these files are original (This step can be skipped if there are MD5 checksum downloaded/copied along with these files), and verify these files again upon using them. · To make sure that files in a removable storage device are secure: In order to avoid bringing in viruses from using the removable storage device, Md5Checker user can calculate, save MD5 checksum in advance and verify files afterwards in the device. It is also a good idea to copy Md5Checker into the device to be able to check files anywhere and anytime. Note: Don't forget to check the copied Md5Checker. · To check out the security status of the system: It will indicate that the system was infected if the MD5 checksum of one executable file was changed without any action. · To find out the virus source: It will indicate that one executable file is the virus source if the MD5 checksum of other several executable files have changed unexpectedly after executed this file. · To calculate MD5 checksum for publishing: File distributors and software authors can use Md5Checker to calculate MD5 checksum of their files and publish them on the website.

Powerful SFV creator and checker, supporting MD5 and CRC32.
AmoK SFV Utility is a small tool for creating and checking .sfv files. SFV stands for "Simple File Verification" and is a standard for describing a checksum for a file list. With a sfv file you can easily check if a download (of multiple files) is complete or if files are missing or files are damaged.
AmoK SFV Utility creates and checks .sfv files. In contrast to most other tools, AmoK SFV Utility cannot only use CRC32 but also MD5 (120 Bit). Furthermore, any user can set a comment in the sfv file.
