Why Crypto Agility Matters Before QDay

[Luca76]

Crypto agility means being able to replace cryptographic algorithms without rebuilding everything from scratch. That matters before QDay because systems that are hard-coded around old assumptions will be harder to migrate when post quantum standards become normal. For small sites, the lesson is simple: keep software current, avoid custom crypto, know where certificates and keys are used, and make future upgrades boring instead of heroic.

Crypto agility is not a flashy phrase, but it is exactly what will separate easy migrations from painful ones.

[Ellie22]

Avoiding custom crypto should be printed on every developer's wall.

[Rory84]

The boring upgrade path is the goal. Heroic last-minute migrations usually mean someone ignored the problem for years.

This fits qday.forum well because it connects quantum risk with normal admin discipline.
