Part of the Secure Coding: Cryptography domain, which makes up ~12% of our current practice bank. EC-Council does not publish an official question count, but from its 120-minute exam (~50–80 total, ~6–10 in this domain), expect 1–2 from this objective — we provide 30 practice questions to prepare you well beyond it.
