Abstract

In today's information-based and all-digital era, data and information exchange is very easy to do from anywhere and anytime. Presentation and storage of information or data can now be stored in digital format and have various forms such as text, image, audio, video, and multimedia. So in the process of digital data exchange required a security to ensure that data sent from the sender to the receiver is completely original and intact data. This research aims to design and build a data security / cryptosystem application and implement the Rivest Shamir Adleman (RSA) algorithm and SHA-512 hash functions into the cryptosystem and the digital data used are document type files (.doc / .docx and .pdf ), text type (.txt) files, and audio (.mp3 and .wav) files. Stages of research conducted include preparation and data collection, needs analysis, process analysis, system design, implementation and testing, and evaluation of results. The result of this research is cryptosystem that can perform the process of encryption and decryption well so that fulfill the security aspects of cryptography that is confidentiality, data integrity, authentication and non-disclosure
