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.

What's new?
  • Forced use of relative paths when saving verification files in the same drive as the hashed files.
  • Fixed: Some verification files may not be saved in the correct format (Vista and later).
  • Fixed: Couple of issues related to VirusTotal service.
  • Fixed: Closing MultiHasher causes MRU list to be erased.
  • Fixed minor bugs.

If you use category All Files it will make a .json file

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.

RapidCRC Unicode v0.3.18 Updated

Checker on 19 Nov 2015
  • 1MB (uncompressed)
  • Released on 18 Nov 2015
  • Suggested by Userfriendly

RapidCRC Unicode is a hashing program capable of checking files, folders, or whole drives. The program includes process priority inside the Window, ability to pause/resume analysis, copy hashes to the clipboard, job queuing, 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.

  • Added SHA3 to shell extension.
  • Added SHA3 extensions to installer.

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.

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.

v2.03 still has same error described by ganamyde

Have a look to HashMyFiles

Bob on 2010-12-13 13:27

I agree that HashMyFiles is the best one for multiple files I have found to date. It's small, quick and even integrates into the right click menu if you want it there.

webfork on 2011-12-31 22:07

Works great to create/verify companion hashes for individual files. Wish there was a way to work in a batch mode.

Now what we need is a way to generate hashes for all files
in directories

abc on 2012-06-09 04:33

Needs support for SHA-2 (SHA-224, SHA-256, SHA-384, and SHA-512), it's becoming more common now days. The interface is quite good though

den4b on 2014-02-20 21:32

I just wanted to let you know that your suggestions have been heard and implemented.

@ Jon: Latest version can compute multiple hashes simultaneously.

@ abc: SHA-256 and SHA-512 have been added in the latest version.
