ANSSI favours a phased transition rather than a single switch, and it makes hybrid schemes mandatory for long-term products from 2025. A hybrid scheme pairs a classical algorithm with a post-quantum one, so a system stays secure if either later proves weak.",[18,28,29],{},"Targeting long-term products first reflects the harvest-now-decrypt-later risk.
