HashTab is a simple free utility that provides Windows extensions to calculate file hashes. HashTab supports many hash algorithms such as MD5, SHA1, SHA2, RipeMD, HAVAL and Whirlpool. While there are many tools around to perform Hash checks, HashTab propably does it the most simple and easy way. It adds a simple tab to the File properties (and hence the name I assume).


When you right-click the file and select properties, click the “File hashes” tab. HashTab quickly calculates all the file hashes on the file. Now, check this against the original hash and see if they match.

For instance, the following is a classical example, I download the following ZIP files of the internet and they are basically two different version of the same software. One download crashed and one downloaded OK. So, lets put Hashtab to test here. I compared them with the Hash from the download websites.

The one failed to properly download didn’t match the Hash from the download site while the other did. Clearly proving the integrity of the file downloaded.

While the Hash problem caused here could be a simple download issue but potential security can be issued by checking the integrity of the file downloaded from the internet and you can’t find a better way to than using HasTab.
