STEP 1: Select a learning scenario from the dropdown menu. Choose from 6 educational scenarios that demonstrate different aspects of cryptographic security and perfect secrecy.

STEP 2: Read the scenario description carefully to understand the cryptographic context, including the plaintext, key, and the specific vulnerability or security feature being demonstrated.

STEP 3: Use the interactive demo section to experiment with encryption. You can modify the plaintext and key values, then click "🔐 Encrypt" to see how the Vernam cipher produces ciphertext through XOR operations.

STEP 4: Make your predictions in the "Your Turn" section:

• Predict what the ciphertext will be for the given plaintext and key
• Assess whether you think the encryption scheme is secure or insecure

STEP 5: Click "✅ Check My Answer" to receive immediate feedback. The system will:

• Verify your ciphertext prediction against the correct XOR result
• Evaluate your security assessment based on cryptographic principles
• Provide detailed explanations about why the scheme is secure or vulnerable

STEP 6: Study the learning feedback to understand:

• The mathematical principles behind perfect secrecy
• Common vulnerabilities like key reuse, pattern predictability, and short key expansion
• Real-world implications of these security concepts

STEP 7: Progress through all scenarios to build comprehensive understanding of:

• When Vernam cipher achieves perfect secrecy (proper key length, randomness, single use)
• What makes encryption schemes vulnerable (key reuse, patterns, information leakage)
• How to identify and analyze cryptographic weaknesses
