Think You Really Get Crypto? Prove It.
Cryptography isn’t just about memorizing algorithms or acronyms.
It’s about knowing how encryption, hashing, and protocols work in real life—and what can go wrong when they’re used the wrong way.
This quiz challenges your real-world understanding of cryptography, from the basics to the stuff that trips up even experienced pros.
You’ll face questions based on:
- Symmetric and asymmetric encryption (AES, RSA, etc.)
- Hashing algorithms and digital signatures
- Real-world crypto protocols (TLS, PGP, etc.)
- Common crypto attacks and pitfalls
- Practical use cases and case studies
Each question has four options. Only one is correct.
No sign-up required.
