Cryptography is essential for protecting data and information in computing systems. Billions of people worldwide rely on cryptography daily. The increasing size of information in web applications, often in petabytes and exabytes, exceeds the capabilities of conventional security frameworks. To address this, we propose a new cryptography algorithm RBJ25 with matrix order N, consisting of three parts: column operation of the matrix, secret key generation, and five subparts to protect information (implementation discussed in detail). Decryption involves three reverse steps. This algorithm is compared with traditional algorithms like AES and ChaCha20. © 2020 Elsevier B.V., All rights reserved.
