Symmetric Key Cryptography: Current Trends?

The present day & age is the time when Information has become the most powerful commodity & communication online or through wireless networks has become an integral part of our lives. The data being transmitted is prone to various passive and active attacks. Thus, information security is in all likelihood the most formidable part of correspondence today. The solution to this problem is the use of cryptography techniques. Cryptography is the art and science of secret writing that changes the message from its typical structure into a garbled structure. The point of this paper is to portray an expansive review of Encryption & Decryption & provide an involved review of the various Symmetric Key Cryptography algorithms.
