Cryptography is the backbone for secure communication over networks. The rapid growth of digital data and its security raises the concern for developing more advanced techniques in cryptography. Cryptography is the physical process that scrambles the information by rearrangement and substitution of content, making it unreadable to anyone except the person capable of unscrambling it. Whereas the techniques used for deciphering a message without any knowledge of enciphering is called as Cryptanalysis i.e., "Breaking the code". Now, cryptography is not limited to only text data.
