How to calculate MD5, SHA-1 and SHA-256 hashes for
files on Windows Mac and Linux.
Introduction: In computing a hash is a string of text which is attributed to each
file. These hashes can be in the form of different hashing algorithms notable
ones include MD5, SHA and SHA-256. For more background information on
hashes and technical information check this out.
These mathematical hashes also have another use which is verifying files.
When you download a file from the internet a number of things can go wrong,
the website hosting the file may have been compromised with malware or you
are downloading a file from an alternative source from the original website
which may have adware or additional components installed. Another common
issue is that the file may be corrupt due to an unstable internet connection
which would result in only parts of the file been downloaded. In this event you
can calculate the hash of the file and then check it against a hash published by
a software developer or original uploader of a file. If the hashes match then the
file is legitimate and or downloaded correctly however if it is different it may
indicate it has been modified or corrupt.
Hash toolbox is a simple software utility to help you calculate the hashes for
different files in a number of popular hashing algorithms including: MD5, SHA
and SHA-256. To get started follow these steps:
- Download and install Python 3 or higher on your computer, this is compatible
with Windows, Mac and Linux and can be found here:
- Once you have downloaded and installed python onto your computer you will
need to download Hash Toolbox which can be found at the link below:
- Next open the .zip file and extract the folder to your desktop or any other
location and open main.py
- From here you should see a window appear, simply choose “open file” and
browse to the file you wish to calculate the hash for.
- After this has completed you should see all the fields populated with the
hashes for each algorithm.
Now you may copy and paste the hash and compare it with whatever hash you
would like to verify.
The software is open source and available on github so if you would like to
