The formula is no longer:
So when you generate that new RSA-4096 or Ed25519 key, do not ask "How long will this last?" Ask: "What is its half-life under load?" And if the answer is less than the life of your session, you are finally building for the world as it is—not as 1.0 wished it to be. key half life 1.1
Key Half-Life 1.1 introduces a crucial refinement: The half-life is not just a function of time, but of access, re-use, and entropy decay. Every time the key unlocks a door—every session, every API call, every wrapped secret—the half-life shortens. Not linearly. Not predictably. But inexorably. The formula is no longer: So when you
