Symmetric encryption is generally faster than asymmetric encryption. That is the basic reason to use symmetric encryption with larger amounts of data. The time difference between the two methods will increase linearly as the amount of data increases.

Modern improvements stores, transfer data at higher rate. Traditional methods which provide security to the information. Using single encryption algorithms are more prone to issues and these are implemented without knowing its shortcomings. This proposed algorithms provides new step to avoid shortcomings. We resemble some famous algorithms as follows. Firstly, we create a new algorithms, In order to provide security issue and time constraint of operation. Secondly, We combine AES using multiplexing of keys, Improvement of DES key size and blowfish algorithm, then we encrypt data using the proposed algorithm. This can enhance the security and complicates the Encryption. In this paper we provide both the encryption and decryption that supports in real time application and algorithm has a practical value.5Index Terms— Hybrid encryption, Advance Encryption Standard(AES), Data Encryption Standard(DES), Blowfish, Key length.I. INTRODUCTION Encryption is a method of converting plain text to cipher text using some base keys and
