After infrastructure and software, the communication in between multiple devices using applications and securing them become most important, cryptography is the mechanism using which we hide the information in public eye site from anybody and is something which is used very popularly almost anything across the internet. So we start with fundamentals of what is cryptography and how cryptography algorithms work and then come to real world scenarios on how currently our data processed on the internet is secured from the eyes of an intruder. Further, the paper enables the students to use cryptography in the most extensive and elaborate manner.
