Custom certificates — Cipher suites

Custom certificates uploaded to Cloudflare will be automatically grouped together into a Certificate Pack before being deployed to the global edge.

A Certificate Pack is a group of certificates that share the same set of hostnames — for example, and * — but use different signature algorithms. Each pack can include up to three certificates, with one from each of the following signature algorithms: SHA-2/RSA, SHA-2/ECDSA, and SHA-1/RSA.
