成为一名密码朋克

If you're living in 2021, you might not realize just how tightly your everyday life is tied to cryptography. Whether it's WeChat messages to friends, residential access cards, ride-hailing app auto-location, buying train tickets, browsing websites, or streaming videos, complex cryptographic algorithms are at work behind all of these. Beyond securing military secrets and protecting bank accounts, it is also the foundation of today's booming blockchain and cryptocurrencies. As a discipline that deals with abstract digital concepts, it is hard to make it engaging without losing its systematic integrity and professional rigor. But in reality, cryptography is full of mystery and fun. Gold, treasure, conspiracy theories... the act of decryption itself sparks natural curiosity. That's why we developed this interactive cryptography video project — Become a Crypto Punk. It starts with basic cryptography fundamentals, guides you to master more complex algorithms, and draws you into the world of cryptography through stories. You'll learn why each cipher was invented, its limitations, and what cipher solutions resolved those flaws. Every cipher comes with detailed explanations, paired with real decryption cases you can try out for yourself.
