Cryptography, specifically encryption, plays a pivotal role in protecting data from unauthorized access. However, not all encryption methods are equally effective, as some exhibit vulnerabilities. This research proposing a novel encryption method that builds upon established techniques to enhance data security. The proposed method combines the strengths of the Festial encryption method and the Advanced Encryption Standard (AES) to create an algorithm that exhibits superior resistance against attacks. The proposed encryption method successfully mitigates vulnerabilities, demonstrating enhanced resilience against unauthorized access attempts and minimizing the potential for data leakage. By prioritizing security and advancing encryption technologies, it can effectively protect personal information, maintain data confidentiality and integrity, and establish a safer digital environment for individuals and organizations.
