Custom certificates — Cipher suites
Before deploying custom certificates to Cloudflare’s global network, Cloudflare automatically groups the certificates into certificate packs.
A certificate pack is a group of certificates that share the same set of hostnames — for example, example.com and *.example.com — but use different signature algorithms.
Each pack can include up to three certificates, one from each of the following signature algorithms:
SHA-2/RSASHA-2/ECDSASHA-1/RSA
