About Caesar Cipher
• Caesar Cipher shifts each letter by a fixed number of positions
• ROT13 is a special case with shift 13 (encrypting twice gives original text)
• Brute Force shows all possible decryptions (0-25 shifts for English)
• Very weak encryption - used for educational purposes only
• Commonly used in CTF challenges and cryptography education
