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 click on "Calculate" button and the tool will immediately show its hash code information along with some important file information such as size, attributes, creation date, etc.
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.
