Nowadays smart gadgets including smart phones and tablets are gaining huge popularity. Comparing with conventional computer, smart phone is easily carried out and provides much computer functionality, such as processing, communication, data storage as well as many computers services such as web browser, video or audio player, video call, GPS, wireless network. However, smart phone have to come long way in terms of security. Encryption is used for security of information in data storage and transmission process. Various encryption algorithms like DES, 3DES, Blowfish, RSA and others are available to secure the data. In DES, key size is too small. In 3DES, key size is increase but the process is slower than other methods. We have used Advanced Encryption Standard algorithm to overcome above problems. AES algorithm is not only for security but also for great speed. It can be implemented on various platforms especially in small devices like mobile phone. Everyday data is shared, transmitted, stored for many purpose like banking, production, research and development. Hence, we need security for information. Encryption can provide security. This application allows user to run this application on android platform to encrypt the file before it is transmitted over the network. It is used for all type of file encryption such as text, docx,video,audio, pdf and image encryption. AES algorithm is used for encryption and decryption.
