From Ancient Codes to Digital Secrets: I built a cryptography time machine 🔐⏳

What if you could crack the oldest Hebrew cipher, decode Spartan military messages, break Caesar's secret communications, or understand how Turing defeated Enigma?

That's exactly what Cryptographia offers: a gamified web experience that transforms 2,500 years of cryptography history into 16 interactive puzzles — designed for schools and cybersecurity awareness training.

Each challenge immerses you in a different era:

🔄 1500 BC → Atbash Cipher (Hebrew tradition)

🛡️ 500 BC → The Spartan Scytale

🔥 150 BC → Polybius Square (Greek torches)

🏛️ 50 BC → Caesar's Cipher

📜 1586 → Vigenère (French diplomacy)

⚡ 1844 → Rail Fence + Morse Code

👑 1854 → Playfair Cipher (British Army)

🔢 1917 → XOR Cipher

⚙️ 1940 → Enigma at Bletchley Park

💻 1960 → Hexadecimal

🖥️ 1963 → Binary Code

🌐 1980 → ROT13 (Internet culture)

📧 1985 → Steganography

📨 1987 → Base64

🔐 1991 → MD5 Hash

📱 1994 → QR Code

The approach? Making cybersecurity education fun and accessible through interactive storytelling. No prior technical knowledge required — students learn fundamental encryption concepts while solving historical puzzles, discovering how each innovation shaped our digital world.

Perfect for classrooms, coding clubs, and cybersecurity awareness programs.

The project is 100% open source, mobile-optimized, and deployed on GitHub Pages.
