The explanation of cipher, which is below the calculator, assumes an elementary knowledge of matrices. WebSep 28, 2024 · We will study Hill Cipher encryption and decryption procedures in solving 2×2 and 3×3 matrices. Although it can be used for higher matrices (4×4, 5×5, or 6×6), it also requires a higher and advanced level of mathematics, adding more complexity. Here, we have used simple examples that provide in-depth knowledge on this topic.
