Abstract: In the modern existence Data communication is a copious key to share the data from one faction to another faction through the nexus or transmission medium using few social media like Whatsapp, Messanger, Facebook in between this, third faction might obtain or retrieve the entropy or data. Cryptography is mainly used for authentication scope. For this equip Cryptography concept and algorithms are applied in an every social media (ex: twitter, Facebook, Instagram, LinkeIn), agencies, institutions, industries, etc. The view of DES, AES and RSA is one the major concern of this paper to explore, how these crypt theories are secure the data by the use of encryption and decryption. This paper takes a simple literature survey and also comparing the relationship between DES, AES and RSA crypt notion. In which they are one of the significant modules to secure and/or the messages using crypt file keys. In these, DES, AES and RSA concepts are used to protect the file with the service of encryption and decryption affair. The main intent of the DES, AES and RSA in cryptography is to secure the files. According to this all the key size is static. In this paper describes how cryptosystems are protecting the plaintext from the unsupported client.
