Guidance about specific algorithms changes as cryptanalysis advances, and an organization that hard-codes one algorithm into its systems must re-engineer them when advice shifts. A system built to swap algorithms can absorb a change like this with far less effort, which is the practical lesson behind the BSI's update.",[18,34,35,38],{},[21,36,37],{},"Why it matters."," The BSI's advice shows that even post-quantum candidates are subject to ongoing scrutiny, and that national agencies will update their recommendations as cryptanalysis progresses. Organizations should read it as a reminder to favour mainstream, well-supported algorithms for new systems and to build crypto agility so that future guidance changes cost less.
