UPDATE: New version 1.0.1 released which comes with a fix for an issue causing font problem in a few systems. A few other enhancements have also been implemented in this new version.
Almost all of use download software and other files from Internet. It might be a free and small software or a large ISO file of a free public beta release of Windows 8. Many times when we download a file from a website, the website also provides hash code (CRC, SHA-1, MD5 or SHA-256) to verify the downloaded file.
"Hash Code" is a unique identifier which helps you in validating the integrity of a file. Many times when you download a large file, you can use its hash code to verify whether the file was downloaded correctly or it got corrupted during the transfer process.
Hash code might come very handy when you download a file using a 3rd party uploading website or a mirror website. You can check the downloaded file with the help of its hash code and can determine whether the file is genuine or was modified to put malicious code.
Now the question comes how to verify hash code of a file? Here is the answer!
"Hash Tool" is a small, free and portable tool created by AskVG reader "Shashi kumar Sinha" which helps you in calculating and verifying hash code of a file.
You just need to run the tool, drag-n-drop the file in its window or select the file using "Browse" button and the tool will immediately show its hash code information.
It shows MD5, CRC32, SHA1 and SHA256 hash values for the file. You can copy a particular hash code using "Copy" button given after the hash code text box.
It also allows you to match hash codes. Just type the hash code in text box and then select the file. It'll immediately match the hash codes and will tell you whether the hash codes are similar or not.
It also allows you to save the hash code values in a text file using "Save To File" button.
Its a portable software so you don't need to install it. Simply run the EXE file and enjoy the software.
You can download it using following link:
Following are the hash values of "Hash Tool":
File : Hash Tool.exe
CRC-32 : FAF66F7C
MD5 : B6706E24B1D6D3DE7C01116562B9BD7B
SHA1 : 24443B77A7B1505984840CCCDDC80CFDF66CFE8C
SHA256 : 4BD709EE8E67E6AD69B9EF4B1B5892D884750151C80E1FFD2C4F194835228BEA

Hi VG! Thanks for share, this will increase my toolbox. :-)
I'm using for several years a similar tool but it is a shell extension, I don't know if you featured it any time, but follow the description:
"The HashCheck Shell Extension makes it easy for anyone to calculate and verify checksums and hashes from Windows Explorer. In addition to integrating file checksumming functionality into Windows, HashCheck can also create and verify SFV files (and other forms of checksum files, such as .md5 files). It is fast and efficient, with a very light disk and memory footprint, and it is open-source."
It is from code.kliu.org/hashcheck and it is an open-source project and didn't disappointed me until now.

Thanks so much Shashi for this most valuable tool ! Thanks also to Vishal for his write up on this software, which is always informative and helpfull ! This software is going to be very usefull in identifying and validating the integrity of a file/files ! Again thankyou for this incrediable tool and it is portable which is another plus ! Cheers Mates !

Nice!
I have Hash Tab installed and this will come in handy for use on machines where it's bad manners to install programs without permission. Thanks
Bill
I agree, HashTab is the best of those programs, for windows. I already use it for long time, and it's integration with windows is very good.
KaYu
Thanks...this tool is very helpful!!
ZD
Wow very handy tool.... but it's require me to run it as an administrator... which I can't use drag and drop feature then... :(
hitesh
Good and usefull tool !
pl show file name on the screen for which hash details are shown. Currently it shows only hash codes (but for which file?)
Shashi kumar Sinha
@Hitesh, It shows hash codes for files you selected or dragged on hash tool window. You can use save to file button to save all required information.
VG
^^ Actually hitesh gave a good idea. Showing file name in program window would be great. You can add a label or text box to show the selected file name or full path. :)

Shashi, can you tell me the code on how to completely hide the maximize and minimize and close buttons?
I am making a program.
Will send it to Vishal soon!
