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.

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.

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.
