TLS Cert Expiry Scanner
A read-only script that scans your fleet's listening TLS ports, extracts every cert in use, and produces a dated report ranking each by days-to-expiry, SANs, issuer, and chain health. Catches the self-signed cert your predecessor installed on the internal API three years ago before it breaks prod on a Sunday.
