What is the difference between Configuration Properties and Secure Configuration Properties?

Configuration Properties: Key-value pairs stored in .yaml or .properties files, loaded via the Configuration Properties component. Values referenced in Mule XML with ${property.key}. Used for environment-specific settings (host, port, endpoint URLs). Multiple property files can be loaded per environment. Secure Configuration Properties: The Secure Properties Tool encrypts sensitive values (passwords, keys, tokens) before storing them in the properties file. The file contains encrypted values in the format ![encrypted_value]. The decryption key is supplied at deployment time as a system/environment property — never stored in the application. Usage: declare the secure properties file with a key and algorithm in the Secure Properties Config element. Both plain and encrypted values can coexist in the same file. In CloudHub, supply the decryption key as a secure property in Runtime Manager deployment settings.
