RekSFV is a checksum generator and verifier that can evaluate files and whole directories. When scanning, the program checks for all supported files and verifies any found checksums. The program supports drag and drop, stay-on-top, minimize to tray, shortcut keys, multiple instances, sound notification and more.

The program supports several hashing algorithms including SFV, MD5, SHA1, SHA256, SHA512.

HashMyFiles v2.23 Updated

billon on 4 May 2017
  • 95KB (uncompressed)
  • Released on 3 May 2017
  • Suggested by infimum

HashMyFiles is a small utility that allows you to generate unique file identifiers (hashes) using a variety of popular checks. 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 range form fast to secure with CRC32, MD5, SHA1, SHA256, SHA384 and SHA512. 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.

What's new?
  • Fixed the 'Mark Hash In Clipboard' option to work with unlimited amount of hashes (in previous versions it was limited to 255 characters).

One cannot copy "SHA-384" and "SHA-512" values from context menu or via a hot key- to get "SHA-384" and "SHA-512" values one have to save to file ("Save Selected Items Ctrl+S") which is awkward.

"How about dropping a gentle hint to ?"
If someone does this I will appreciate- I remember that long time ago I messaged NirSoft about something and since I got no response I will not try again. More- lately I am not in a very gentle mood. ;)

RapidCRC Unicode v0.3.23

billon on 8 Apr 2017
  • 786KB (uncompressed)
  • Released on 7 Apr 2017
  • 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 / Win10
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. Delete rcrcshex.dll or rcrcshex64.dll
  3. Create an empty text file called options_unicode.bin in the same folder
  4. Launch RapidCRC.exe
Similar/alternative apps: FileVerifier++
What's new? Fixed:
  • Usage of relative path names in hash files.
  • SHA3 calculation - previously RapidCRC was producing raw keccak hashes. This also includes a change of the file extension to sha3-224/256/512, which now matches the file extension of HashCheck with sha2/3.

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

MultiHasher v2.9

billon on 28 Jan 2017
  • 6MB (uncompressed)
  • Released on 26 Jan 2017
  • 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

How to extract:
  1. Download the ZIP package and extract to a folder of your choice

  3. In the application folder, create an empty text file and rename it to User Preferences.json
  4. Launch MultiHasher.exe

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.

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.
