Nowadays, distributed resources from the cloud computing are shared in open environment via network such as medical report, banking and privacy information. Therefore, the user can access their data easily from anywhere. At the same time, there are several problems which are the data might be altered and steal by the hacker or unauthorized user. This problem makes the environment is unsafe to share the data. Hence, the data need the security to keep it safe. So, the encryption will give the protection. It is used during transmission process to encrypt the information. This project can help the user to keep their information or data in secret message to the receiver in original message without alter by unauthorized user. The encrypt file that sent to the receiver on the Gmail need to decrypt before the user can open the file. The file is transferred securely without being modified. The privacy of the data is being protected from the malicious insider during transmission to the cloud. In this project, it focused on text document type. The hybrid cryptography is used to encrypt and decrypt the file. It used the symmetric and asymmetric key to make it more secured. The AES algorithm is for encrypt the file and RSA algorithm is used for decrypt the file. This algorithm is used because it fast and more secure for transferring the file. The aim of this project is to ensure the confidential data is not reachable from unauthorized user by implementing the key of encryption. In the future, the researcher can do some cryptography on the image, video and audio to make it secured during the transmission.
