Key Half Life 1.1 [repack] | Complete

[ P(t) = 2^{-t/T} ]

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. [ P(t) = 2^{-t/T} ] So when you

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. It is a design parameter

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.

Version 1.0 of key half-life was simple. It said: After time T, a cryptographic key has a 50% chance of being compromised. That was the era of Moore’s Law as a gentle slope, where attack surfaces were smaller and trust was implicit. But threats don't stand still.

In the quiet hum of the data center, where servers breathe recycled air and LEDs blink in endless binary rhythm, a clock is ticking. Not the clock of seconds or minutes, but one measured in decryption attempts, brute-force hashes, and quantum advance warnings. This is the half-life of a key—specifically, Key Half-Life 1.1.
