Key Half Life 1.1 Site

Where ( u ) is the number of uses, and ( \lambda ) is the leakage coefficient—a number you must empirically measure, because every system has its own.

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

This is the quiet revolution of 1.1: moving from static security to kinetic security . The half-life is not a warning. It is a design parameter. Where ( u ) is the number of

Consider a master key used to derive subkeys for microservices. In version 1.0, you might rotate that master key every 90 days. In 1.1, you realize: after 1000 derivations, the key’s effective strength has halved. Not because the math broke, but because side channels, memory scraping, and log leaks chip away at the secret bit by bit. The half-life is not a warning
