<![CDATA[Cryptography is the science or art of securing messages and is done by a cryptographer. The guaranteed data includes several aspects such as messages security such as confidentiality, data integrity, and authentication. One of the cryptographic algorithms that are often used in securing data is the RSA algorithm. RSA stands for the names of the founders of this algorithm, namely Ron, Shamir, and Adleman. RSA is an algorithm that uses the concept of public-key cryptography (the asymmetry/key used to encrypt is different from the one used to decrypt). The importance of information causes the desired information to be accessed only by certain people. The unwanted fall of information to other parties can be detrimental to the party holding the data. This study discusses the use of the RSA algorithm to build a document security system prototype. The study results explain that the RSA algorithm can secure essential documents based on university case studies]]>
