Interactive Encryption Simulator

Test your understanding of Plaintext, Keys, and Ciphertext.

The Scenario: You are sending a private message over a wireless network. To stop interceptors from reading it, we will use a basic algorithm (a Caesar Cipher) to scramble it.

1. Enter your Plaintext (The original message)

2. Choose your Encryption Key Shift: 3

This key tells the algorithm how many letters to shift forward in the alphabet.

3. Intercepted Ciphertext (The scrambled data sent over the network)

Exam Connection

If a hacker intercepts the wireless signal, they only see the Ciphertext above. Without knowing the specific Key you used, the intercepted data is meaningless to them.
