Implementation and Analysis of various Encryption Techniques with Blowfish on various Data Files

In today's information technology era, data security is a big concern. Because data is stored in various locations throughout the world, it becomes especially dangerous in the cloud environment. Encryption is a technique, and various encryption methods play an imperative role to provide cloud data security. In cloud computing, encryption algorithms are employed to protect data security. The goal of data security is to limit access to just those who are concerned and permitted. In this work, we explain file size using AES, DES, BLOWFISH and Pailier, and compare their performance based on the examination of various data formats such as text files, image files, and word documents, among others, at various setups for individual users.
