Evolution of cloud makes users to manage the data and applications online. It is the responsibility of the cloud service providers to care of data secure in terms of transferring and efficient by providing reliable performance. There are many challenges that are faced by the service providers to achieve the trust of the user. User feels insecure while the data is send to the cloud servers, when the data is more confident and uses applications that provide security to the data (by encryption and decryption). These applications to encrypt data will consume more time and systems resources. All these applications work depending upon the operating system of the user. This proposed approach will reduce user’s burden in interacting to the cloud through browsers add-on. This add-on is designed by AES encryption methodology with a SHA-2 key which is proved to be secure. The main aim of this paper is to explore various environments and design cloud based applications which are more user friendly at the same time reduce hardware cost. This design also highlights a threat to the mailing servers as they can’t find the transmitting information from the user.
