Information and data can be easily and quickly sent to consumers via a computer network. Data and information can be easily and quickly accessed by users through a computer network. Of course, this is dangerous if unauthorized persons have access to the data transmitted and cause a data breach or leakage. Security issues are one of the most important aspects of information systems. In particular, technological advances in data security systems to maintain data security have grown rapidly. Scientific disciplines such as encryption and steganography are being developed to maintain data security. (Program et al., 2016) In the implementation of not only one security technique, but can be done in combination in the security of information data. This research aims to create data security by applying cryptography to text messages, document files, and images online with advanced encryption standard (AES) algorithm calculation methods. AES is a cryptographic algorithm that can be used to eat data where the algorithm is a symmetric chipertext block that can encrypt and decrypt information. The result of the study is that users can encrypt text messages, document files, and images so that the security of the information data can be maintained because of security. (Ikbal, 2007)
