Abstract
Data security in digital communications is an essential aspect in today's information age. Cryptography has long been used as a solution to protect the privacy of data through the use of complex encryption algorithms. Two classical cryptographic algorithms that have proven to be effective are the Caesar cipher and the Affine cipher. However, both have their own weaknesses. This research proposes a new approach by combining the strengths of Caesar cipher and Affine cipher so that the security of a message becomes stronger. In this approach, the Caesar cipher is used as the first stage of the encryption process, followed by the application of the fine cipher as the second stage. The first stage with Caesar cipher aims to scramble open text archetypes, while the second stage with Affine cipher provides additional mathematical transformations on encrypted data.
