Abstract

Data is very important for humans, data is also needed to collect information. But given that cybercrime crime has occurred in the digital era today. Therefore, data security is very important to be considered. Inside the company has important data. One of the companies in Karawang, namely PT Adyawinsa Stamping Industries, has a data input application that is the company's asset data. Many data crime problems make database systems vulnerable to manipulation. Therefore, the implementation of data security for asset data is implemented using Playfair Cipher cryptography. The Playfair Cipher encrypts letter pairs (bigram or digraph) into letter pairs, not single letters as in other classic ciphers. The purpose of this study is an application that is able to encrypt data using the Playfair Cipher cryptographic algorithm and the application is also capable of performing decryption of data in a database that has been encrypted then entering data that has been encrypted into the database. The results of this study indicate that the system built has successfully performed encryption and decryption of asset data against user names and asset names using the Playfair Cipher cryptographic algorithm. There are differences in the results of the decryption tested in this study. However, the application can set the decryption results with the tools contained in the application.
