Cryptography Fundamentals Assessment

100 multiple-choice questions spanning classical ciphers, symmetric and asymmetric cryptography, hashing and MACs, key management and PKI, TLS and network security, authentication, post-quantum cryptography, and general security principles. Answer each question for immediate feedback and an explanation, then get a final score and tier at the end. Takes about 35-45 minutes -- or stop anytime, your score reflects what you've answered so far.

What This Assessment Covers

The 100 questions span the full arc of cryptography as a practical field, organized across nine areas: classical ciphers and cryptanalysis, symmetric cryptography, asymmetric cryptography, hash functions and MACs, key management and PKI, TLS and network security, authentication and passwords, post-quantum cryptography, and general security principles and attack patterns. It's designed as a genuine knowledge check, not a marketing quiz — every question has one unambiguously correct answer and a real explanation, and answer order is randomized per question so there's no positional pattern to game.
