Dive into classical cryptography with Explerify's Hill Cipher Simulator. This interactive tool helps students explore encryption and decryption using the Hill cipher.
Enter a plaintext message and define a key matrix, then see how encryption transforms letters into numbers and applies modular matrix multiplication to produce ciphertext. Change the key matrix to decrypt messages back to plaintext and explore how linear algebra powers this cipher.
Ideal for high school and undergraduate students, this simulator builds intuition about classical encryption techniques, matrix-based ciphers, modular arithmetic, and secure communication concepts.
