Typically, a secret is a password that you share with CDNetworks in order for the CDN configuration to work. For example, a secret could be a key used to authenticate client requests to your origin server. By creating a secret and referring to it using the secret's name via the syntax $SECRET(secretName), the key itself would not be exposed when viewing a property through the CDN Pro portal or fetching it using the CDN Pro API.
Secrets can be referenced in:
$SECRET(secretName) syntax in your Edge Logic configuration.Secrets are managed from the Secrets page. To display this page, click Edge Configurations in the left pane, and then select Secrets.
The following figure shows the key elements on the page, and the table following the figure describes them.
