dns-01 Cloudflare
Cert Warden has native support for Cloudflare as a DNS provider.
There are two options to configure Cloudflare. You can either create a scoped API Token or use a Global API Key.
Configuration
As with all providers, domains that should use this provider must be
specified. One wildcard provider can be configured with a sole
domain of * which will be used if Cert Warden doesn't find a domain
name on any other provider.
Then use the dropdown box to select one of the two below options.
Scoped API Token
This is the preferred option as compromise of the token will only result in a partial compromise of the related account. Additionally, there is no reason to give Cert Warden complete access to a Cloudflare account.
Global API Key
This options involves using a Cloudflare account's global key which gives full and complete access to the account.
Due to the breadth of access this key grants, it is STRONGLY recommended you DO NOT use this option.
You will need to input the account's email address and API Key.
