Security Why Hybrid Encryption Matters 13 min read Why Use Two Locks When One Should Be Enough? The front door of your house probably has one lock. That works fine for everyday life. But the vault at a bank has a time-lock mechanism, a combination dial, and a physical key requirement. Nuclear missile silos require two officers to turn their keys simultaneously. Airplane cockpit doors have multiple independent locking mechanisms. The more important something is, the more layers of protection it gets. Cryptographers apply the same principle through something called hybrid encryption : using two completely independent encryption algorithms at the same time, so that an attacker must break both to access the data. QNSQY combines two key encapsulation algorithms in every encryption operation: ML-KEM : A post-quantum algorithm standardized by NIST as FIPS 203 in August 2024. Based on lattice mathematics that quantum computers cannot efficiently solve.…
