Abstract - There are billions and trillions of pieces of data being produced at any given time because to the internet. The majority of it is connected to the financial industry, the intelligence sector, or perhaps personal information about people and the country. Therefore, it is essential to safeguard and protect it. Data is encrypted using cryptography, which also secures its transmission over the internet. Different methods have developed over time to cypher the original text. The most used cryptographic algorithm is the Playfair algorithm. However, it is exploited by brute force. By altering the matrix and tricking the attackers into thinking it is a different cipher, the suggested approach enhances the performance of the conventional Playfair cypher.
