Setting CA Universal SSL Cloudflare

Saat proxy pada record DNS diaktifkan, Cloudflare akan otomatis menerbitkan Universal SSL sehingga domain atau subdomain dapat diakses melalui https://.

Secara default, sertifikat SSL biasanya diterbitkan menggunakan CA Let’s Encrypt, namun Cloudflare menyediakan opsi CA lain seperti Google Trust Services, Sectigo, dan SSL.com (tergantung ketersediaan akun/zone).

ZONE_ID=ID
AUTH_KEY=KEY
AUTH_EMAIL=EMAIL

curl -X GET \
  "https://api.cloudflare.com/client/v4/zones/$ZONE_ID/ssl/universal/settings" \
  -H "X-Auth-Key: $AUTH_KEY" \
  -H "X-Auth-Email: $AUTH_EMAIL"

  --data '{"certificate_authority":"lets_encrypt"}'

Setelah CA diganti, sertifikat SSL yang sedang aktif tidak selalu langsung berubah ke CA baru. Cloudflare dapat tetap menggunakan sertifikat lama hingga masa berlaku habis atau sampai dilakukan re-issuance otomatis.

Namun, jika Anda menambahkan subdomain baru dengan status proxy aktif, biasanya sertifikat baru akan langsung diterbitkan menggunakan CA yang saat itu sedang dipilih.
