A certificate secret's expiry was only ever what someone typed in, so
a renewed cert (or a wrong date) meant the app's reminders were
silently wrong. A certificate secret can now be given a host:port; the
app opens a real TLS connection and reads the certificate's actual
expiry — on create/edit (if the host changes), daily, and via a
per-row "Check now" — and keeps expiryDate in sync. Because the daily
refresh runs before the existing expiry check, the reminder is always
computed from what's actually being served.
Verification is deliberately off for the connection: homelab services
routinely serve self-signed/internal-CA certs, and an already-expired
one is exactly the case worth reporting, which a verifying connection
would refuse before exposing the dates.
Failure handling avoids the silent-staleness this is meant to fix: a
failed check keeps the last known date, records why on the row (shown
as a "Check failed" badge), and is listed in the daily secrets
notification. Creating a monitored secret whose host can't be reached
and with no manual date is rejected with the reason rather than saved
blank. A non-TLS port (the likeliest typo) gets a plain-language
error instead of raw OpenSSL output.
Server-side connections to a user-supplied host:port need the same
operator role that already gates editing secrets (and running Semaphore
templates, which is strictly more powerful); the host is validated
against a strict character set before any connection is made.
New nullable secrets columns (check_host, check_port, last_checked_at,
last_check_error) via migration 0007; existing rows are unaffected.
Verified against real TLS servers (openssl-generated certs) and the
real secrets router with a stubbed session: a live 45-day cert read
back as the correct date via both an IP host (no SNI) and a hostname;
an already-expired cert reported its past date and shows as expired;
refused connections, a server that accepts but never answers (times
out), and a plain non-TLS server each produced a descriptive error
rather than a hang or crash. Through the router: create with a host
and no date reads the date; unreachable host with no date -> 400 with
the reason; unreachable with a manual date -> saved with the error
recorded; host on a non-certificate type and an invalid host string
-> 400; a hand-typed date on a monitored secret is ignored; changing
the host re-checks immediately; changing the type away from
certificate ends monitoring; a viewer gets 403 on Check now. 23 checks,
all passing (a first re-run showed 2 spurious failures that were leftover
rows from the previous run's scratch database, confirmed by a clean re-run).
Real dev database mtime untouched throughout.
