Peace be upon you
How are you guys? today I am going to show you something I have done as a data security assignment, the assignment was a presentation and application, me and other 3 guys were suppose to write something about MARS and Application, I helped in the Presentation and took the application :D, do you understand anything?
Well, let us begin the whole thing is about encryption algorithm called MARS, developer by IBM, you can find more about it
And here is the presentation
So, the idea is to make application for the ready made code of IBM, so the plane was todo simple application that do simple encryption and decryption, here is snapshots for the application, you can find the code here (Cocoa Touch Objective C project)
Lets see the application.
Here is the result, and as we use OFB + Random IV, when you reencrypt by just clicking back and next, you will get anther result
Now you have got your data
I have added little part for some fun it is the Mode of Operation , you can read more about it here
The mode that I have used was "OFB, output feed back"
I hope that you enjoy the application and the presentation :)
Thanks for your time.
