EXECUTIVE SUMMARY: This study entitled Development of Database in Encoding and Decoding Message Using Isolated Prime Number was conducted at the University of Rizal System-Morong, Rizal during this academic year 2018-2019. The purpose of this study was to show that a two isolated prime numbers can be a key generation to create a cryptography for securing someone's message and applying it into a database for much fluent way. By the use of a developed formula, and using the two given isolated prime numbers, the researchers created a public key for creating a key pattern that served as their guide for encrypting message. It also used encoding formula when creating the key pattern. Extended Euclidean was used for getting the private key that served as guide for decrypting message and also used decoding formula for deciphering the encrypted message. The researchers found out that database is capable in encoding and decoding message using isolated prime numbers. It helps to secure the message of two people by encrypting and decrypting. The researchers recommended future researchers to conduct further related studies.
