Implementation of Symmetric Encryption Algorithms

Cryptography considered being the most vital component in information security because it is responsible for securing all information passed through networked computers.The discussions in this paper include an overview of cryptography and symmetric encryption.This paper also discusses some of the algorithms used in our research.This paper aims to design an application that consist of some symmetric encryption algorithms which allow users to encrypt and decrypt different size of files, also the application can be used as a test field to compare between different symmetric algorithms.
