  • Released on 13 Mar 2016
  • Suggested by I am Baas

MD5 Checksum Tool is a drag-and-drop hash checking tool that can generate a file checksum to analyze if a file has changed, usually to affirm it's legitimate and uncorrupted. The program can scan a folder and subfolders (recursively), as well as provide a report of all files, their size, and checksums. Supports very large files (4GB+) and includes a progress bar to estimate remaining time.

The program will allow the comparison of two files with their respective checksums and supports MD5, SHA1, SHA256, SHA384 and SHA512 checksums.

A 64-bit version is available (within the x64 folder).

System Requirements: Win2K / WinXP / Vista / Win7 / Win8 / Win10

There's no [portable] link anymore on the homepage (where other apps do) and I can verify that v2.8.0.0 writes it's setting to the registry.

Disregard my previous comment, something screwed up my regShot. It only writes the EulaAccepted key to the registry. Not stealth and a little annoying but otherwise portable...

Couldn't get this to run reliably at all. Constant freezes; always had to kill it with Task Manager.

HashMyFiles v2.18 Updated

webfork on 24 Mar 2016
  • 88KB (uncompressed)
  • Released on 23 Mar 2016
  • Suggested by infimum

HashMyFiles is a small utility that allows you to generate unique file identifiers (hashes) using a variety of different popular tools. These can help determine if a file has been modified or corrupted, as well as help determine the file's reputation by submitting to the VirusTotal database for malware analysis.

Formats supported ranging form fast to secure include CRC32, MD5, SHA1, 256, 384 and 512. The various hashing information can be saved to a report (text/html/xml) that includes name, path, dates, file size, version, and other info.

System Requirements: Win2K / WinXP / Vista / Win7 / Win8 / Win10
Writes settings to: Application folder
Stealth: ? Yes
Unicode support: Yes
License: Freeware
How to extract: Download the ZIP package (ANSI/Unicode) and extract to a folder of your choice. Launch HashMyFiles.exe.

I dont see a forum link for this post, I also sent the author a report, testing this version (1.97) he still didnt fix it.
I agree that NirSoft utilities are a must have, i myself use few.
From my own experience, the author is lazy when it comes to feedback.

Anyway, to produce the bug...
-Drop a large file and sop the process before its complete, lets say at 2%
-Drop a small file and it will scan old file first.
Most likely he doesn't empty a variable when you break/stop the operation. Should be an easy fix.

@Ganamyde: Point taken. Thanks for the breakdown.

MultiHasher v2.8.2 Updated

billon on 1 Mar 2016
  • 7MB (uncompressed)
  • Released on 29 Feb 2016
  • Suggested by guinness

MultiHasher is a drag-and-drop tool for creating and checking file hashes, useful for checking data integrity. The program will check files, folders, and even text using a variety of methods with both pause and cancel options for large operations. The program can then compare digests to detect changes as well as query the result to the VirusTotal database. A search tool lets you quickly track down both files or specific hashes from long lists.

A recursive checking option (entire directory trees) is available in the options menu. The program can also use existing, standard hash files such as MHX, SFV, MD5Sum, etc. to check integrity.

Supports 64-bit operating systems and available algorithms include from fastest to most secure: CRC32, MD5, RIPEMD-160, SHA 1, 256, 384, and 512. Can include one, some, or all algorithms available in testing.

System Requirements: WinXP / Vista / Win7 / Win8 / Win10
Writes settings to: Application folder
Stealth: ? Yes
License: Freeware
How to extract:
  1. Download the ZIP package and extract to a folder of your choice
  2. In the application folder, create an empty text file and rename it to:

    User Preferences.json

  3. Launch MultiHasher.exe

  • Fixed critical bugs in most hash algorithms (introduced in v2.8) that could result in wrong hash values being calculated.
  • Minor UI tweaks.
  • Fixed minor bugs.

it opens a browser for the VT results :(

PeStudio shows the results in its own GUI.

would be nice to have program like this that you enter a folder or partition of say all your portable apps and this program works slowly in the background at like 5% of CPU and checks all hashes against VT, option to upload those unknown, then stores to a small database and gives the option to recheck every so often against the hashes stored, etc. And option to select filetypes that dont need to be scanned. Would be a good security program.

I've been using this program a lot for the MD5/SHA1 and VirusTotal features for postings here on PFW. That said, I still prefer RapidCRC Unicode for hashing / checking lots of files.

Enternal on 2016-01-08 13:55

Two bugs to be aware of. The first bug is:
Make a new directory with some files in it. Drag the folder into MultiHasher and make MD5 hash calculations for all those files. Save the hash list in MultiHasher own hash format (mhx). Clear the list. Load the hash list. Drag the folder back into MultiHasher to "add" the folder. MultiHasher then hangs. Versions prior to worked fine.

With, a new major bug:
MultiHasher refuses to load mhx files that are over a certain size. From what I test so far, any mhx files that are larger than roughly 150 KB refuses to load when you drag and drop the mhx files into the MultiHasher window. Instead, MultiHasher will treat it as a regular file to be hashed rather than a list of hashes. If you tried to load the file manually (Ctrl+O), MultiHasher will do nothing for these files. Files that are less than 100 KB loads perfectly both ways.

Both bugs have been reported (1st bug about a year ago). However author never replied and even deleted the thread and my forum account. In other words, be aware of any potential new problems with new versions and always keep old versions.

These bugs does not occur if you use file formats other than their own mhx format.

Anyways, like Webfork, I now prefer RapidCRC Unicode over this. RapidCRC Unicode has been rock solid and all bugs that I have reported to the author were taken care of or were promptly responded to.

RapidCRC Unicode v0.3.19

webfork on 22 Dec 2015
  • 1MB (uncompressed)
  • Released on 6 Dec 2015
  • Suggested by Userfriendly

RapidCRC Unicode is a hashing program capable of checking and verifying the integrity of files, folders, or whole drives. The program includes process priority, ability to pause/resume analysis, job queuing, easily copy hashes to the clipboard, and multi-threaded checks. If using checksum files (e.g. .sfv or .md5) for future verification, options include the ability to generate for every analyzed file, directory, or a single checksum with all hash data.

Includes direct support for CRC hashing in the filename (common for anime releases) for example: "MyFile [45DEF3A0].avi") Other algorithms range from fast to secure, including SFV(CRC32), MD5, ED2K, SHA-1, SHA-256, and SHA-512.

A 64-bit version is available on download page. Based on the original RapidCRC but updated with extended unicode support.

System Requirements: Win2K / WinXP / Vista / Win7 / Win8
Writes settings to: Application folder
Stealth: ? Yes
Unicode support: Yes
License: GPL
How to extract:
  1. Download the Archive or Archive (x64) RAR package and extract using 7-zip or similar program to a folder of your choice
  2. Create an empty text file called options_unicode.bin in the same folder
  3. Launch RapidCRC.exe
Optionally, delete rcrcshex.dll or rcrcshex64.dll for 64-bit version. Otherwise, this shell extension file will need to be manually registered with Regsvr32 to use.

What's new?
  • Added right-click drop menu that offers the same options as the shell extension or the open file dialog (can also be triggered by holding ctrl when dropping).
  • Added option to not overwrite existing hash files in the "create ... for all" modes.

This is currently my go-to program. I tend to add it to the "send to" menu on machines I'm currently using and it works beautifully to check one or more files. Also, the ability to insert the hash directly into the file name makes so much sense. Just drag-and-drop it into the window and instantly know if there's a problem. Great solution to the multi-step check.

shoover on 2016-02-21 09:17

I think there is something wrong with the "CRC into Filename" function. This occurs with files that lack a file extension.
