Hi Guys! in this article we will somehow go to the world of cryptography wherein the hackers play a hide and seek or cat and mouse with the cryptographers. The cryptographers develop encryption to secure information...now hackers break it.....steal something. The technology users caught in between believing that their private files is secure.....only to realize that hackers has stolen their private digital belongings ranging from as simple as picture of the lady you fantasize..... to as serious as bank account......etc. Anyway, in here I just show you a simple way to demonstrate bit flipping on stream cipher. This is changing part of an stream cipher encrypted message without knowing the key. I will be using RC4 which is a popular stream cipher. Then using VBA on the programming side to show you guys how to change encrypted message content.
