Curious Findings: HashTab

January 4th, 2008 | EvilSeph | Curious Findings

Program Description
The best way to verify if a file is what you’re expecting is to check if the unknown file’s hash matches the hash of the file you’re expecting (usually given to you on the download page of a program, for example).

HashTab Screenshot

Since this is the internet, everyone and their dog can start up a website for a small fee – or no fee at all – which brings to question the validity of the majority of the internet’s information. This is where file hashes come into play.

As you may or may not know, I’m quite into the PSP Scene and as such often find myself updating to the latest custom firmware available or what not which usually requires official Sony update eboots.

Unfortunately, some sites feel it is necessary to upload corrupted eboots (or they do it by mistake?), upload the wrong file and name it something else…or whatever. They just like to deceive you. Or I could just be paranoid and your download could just be corrupted for another reason . The only way for you to really check how valid a file someone offers to you is, is by checking its file hash against the hash provided by the author.

And here’s where HashTab (developed by Cody Batt) helps us out. After you install HashTab, whenever you view a files properties, you will now see a new File Hashes tab where you can easily calculate the files various hashes.

HashTab supports more hash types than what is shown in the screenshot, just right click the area where the hashes are displayed and click on “Settings…” to choose the types of hashes you’d like to see.

Another useful feature HashTab provides is an interface to choose a file to compare against the current file you are dealing with. No need to type hashes out or copy and paste them, just choose the file and HashTab does the work for you.

License Type
HashTab is completely free, all you have to do is agree that “HashTab is the coolest thing ever.”

System Requirements
Windows is required in order for this application to function.

Installation

Run the setup program you downloaded and follow the on screen instructions

Uninstallation

Nice shell extension, but MD4 hash is broken in current version 2.1. Big files (up to 4GB) are not correct.

I just want to know how this program hashes so fast.. Visual basic built in hash functions are REDICULOUSLY slow. A dll called quickhash.dll for hashes costs money to remove a delay caused by the trial version AND it’s slower than this program…

Is Cody Batt reading this?
Hashtab 2.1 doesn’t work when I use it as restricted user (Windows XP Home).
Can you verify this?
Cody Batt Says:

Hey Gerolf, Cody here… you can send me email at skry…@gmail.com. What do you mean by doesn’t work? Tab doesn’t show up? Crashes? Doesn’t return the right hashes?

I can’t see why it wouldn’t work for a restricted user, unless that user doesn’t have rights to even read the file, then of course it can’t be hashed.

But how do you verify that the HashTab download _itself_ is legit?
Francois Says:

Follow-up to above post:
Before installing it, that is. Don’t see any digital signature when downloading in either Firefox or Opera. (Hardly exceptional in that as digital signatures seem to be exception rather than the rule for downloads, something I don’t get)

Also, after installing, HashTab shows CRC32 and SHA-1 hashes for the HashTab Setup file itself, yet
http://beeblebrox.org/hashtab/ only gives the MD5.

HashTab does work to visually show the MD5 hash of a file, but do not use to compare with another md5sum file as it will fail. My experience has been with the firmware files from Avocent. Avocent will allow download of the f/w file and download of the md5sum file but they place extra characters in the md5sum file that makes it fail with HashTab. The only way I can truly verify a file is to take 2 minutes and check each character in the MD5 from HashTab and the md5sum file from the source…time consuming but it works. HashTab is good for finding the MD5sum of a file but not for comparing it to another file.

Worked great when first installed… but now the Hash tab doesn’t show up, and uninstall/reinstall doesn’t bring it back. Vista 64bit OS.

Well, after further fiddling, I find that it does show up if I launch explorer myself, but not if launched by Vuze.

I believe the information covered in the discussion is top notch. I’ve been doing a research on the subject and your blog just cleared up a lot of questions. I am working on a term papers and research paper for my English class and currently reading lots of blogs to study.

The custom essay writing can demonstrate a writing skillfulness of some students. But it needs a lot of efforts to compose the perfect quality persuasive research paper. The best writing services could advice to buy research paper referring to this good topic to save time and money.
