Dive into classical cryptography with Explerify's Substitution Cipher Simulator. This interactive tool lets students explore encryption and decryption using classical substitution ciphers.
Enter a plaintext message and a substitution key, then see how the message is encrypted into ciphertext. Change the key to decrypt messages back to plaintext. Visualize how letter substitution works and how different keys affect the output.
Ideal for high school and undergraduate students, this simulator helps build intuition about classical encryption techniques, key sensitivity, and secure communication concepts.
