Hashculator

A tool to compute file hash for a single file or file in the entire directory.

What's the deal?

Linux has its own commandline in computing for the hash file in its system. Thus a simple,

echo -n [file]| md5sum

would do the trick.

In Windows there are 2 ways. One way, you can utilize certutil.exe by commmandline. Thus, this..

Another way you can use powershell command Get-FileHash to provide what you're looking for.

So, what's the deal with this tool? During a certain malware investigation activity I am having, applying those ways add up to my task beyond the investigation itself. So that got me thinking to create a program that would compute for the hash of a single file or files in your local or external drive. I have designed this program to be more efficient and faster, all you need is to provide the exact file location.

Functionalities

Launching the app , we are to decide to what hash algorithm we want to have

Let's try the SHA1 conversion, with just 3 keyboard hits.

And voila! We just have the entire directory's SHA1 hash.

Let's then test for just a file. We want to have the SHA1 of whois_result.json on the same directory.

Then above is the result, same hash value as what is on above.

More....

Let's mess with the tool a little bit more. For instance, we wanted to get the entire SHA256 of my external drive, D.

Finally let's try to get the md5 of file locaiton C:\IT Sec Reads

That's my hashcalc tool, please provide comments for feedbacks and suggestions.
