Validity window of the gateway leaf cert in days (default 30). Validity window of the gateway leaf cert in days (default ~10y).
Short-lived by design ahead of the CA/Browser-Forum's move The leaf is re-signed by the (stable) CA when it is missing or
toward ~47-day max lifetimes which bounds the blast radius of a within 30 days of expiry; because it shares the CA anchor, a
leaf-key compromise. The leaf is re-signed by the (stable) CA rotation does not disturb consumer trust. Browsers may warn on
when it is missing or near expiry; because it shares the CA long-lived leaves, but agents and federation peers validate
anchor, a rotation does not disturb consumer trust. Agents and against the CA, not browser CA/B-forum limits.
federation peers validate against the CA, not browser CA/B-forum
limits. NOTE: at this short a window the re-sign must run more
often than the leaf lifetime. Today `hive-tls-ca` re-signs at
service activation (boot/rebuild) only there is no periodic
re-sign timer yet so a hive that does not reboot within the
validity window would let the leaf expire. Keep that in mind (or
add a re-sign timer) when running a hive that stays up for long
stretches without a rebuild.
