Abstract

The communication process always happens all the time. Various communication tools developed and used to support the achievement of the communication process. Various models of communication tools can be found, either in the form of physical (hardware) or in the form of applications (software). Interconnected computers allowing users to communicate with each other and share information.
In practice, computer network users are often faced with communication problems between users. The existence of such applications can support the successful use of a computer network within an agency.Chat application is used as a medium of communication among fellow computer users connected in a network, whether through text, image, or sound.
The built application uses the program aspect implemented into the Advanced Encryption Standard (AES) algorithm used as the standard cryptographic algorithm of Caesar Chiper. AES itself is a cryptographic algorithm by using a caesar chiper algorithm that can encrypt and decrypt data blocks. This software development is done in several stages of developer method, some of the stages, namely requirement analysis, system design, implementation, system testing and maintenance.
