8.8Mule Secure Configuration Properties

Mule has a Secure Configuration Properties extension.

It lets you store encrypted values in YAML or .properties files.

Encrypted values look conceptually like:

salesforce:
  clientSecret: "![encrypted-value-here]"

MuleSoft requires encrypted values to be wrapped in:

![...]

and allows YAML or properties files.

Then your Mule configuration refers to the secure property.
