KIMI's optional-SSL commit hardened ssl_protocols/ssl_ciphers per-vhost but
left the system nginx.conf http{} defaults untouched, so the default server
and any non-ServerKit vhost could still negotiate TLS 1.0/1.1 and weak ciphers
(the scan's "insecure TLS versions" / "weak ciphers in TLS 1.2" findings).
- install.sh: harden_global_tls() rewrites (or injects) ssl_protocols and
ssl_ciphers in /etc/nginx/nginx.conf to TLS1.2/1.3 + AEAD-only. Editing the
line in place avoids nginx's duplicate-directive error on Debian/Ubuntu,
which already set ssl_protocols in http{}.
- update.sh: re-applies the floor so existing installs harden on upgrade too.
- Persist the panel domain to /etc/serverkit/panel-domain; update.sh recovers
it from there (or the live cert path) instead of the commented-out .env
SERVERKIT_PUBLIC_URL grep, which never matched -> secure installs were
getting the YOUR_DOMAIN placeholder re-applied and nginx -t failing on update.
- update.sh now degrades to the HTTP config when a secure cert is missing,
rather than leaving nginx unable to reload.
Global TLS settings are inert in HTTP-only mode, so optional SSL is unaffected.
