WebJun 6, 2024 · 1 Answer. Theoretically as pointed out by @CodesInChaos there is no need to rotate keys as long as they remain secret. Also as @CodesInChaos points out, you need to architect the system for key rotation in the event of key compromise. The best way to do that is to build key rotation into the app and operational tooling, and then put procedures ...
