What method is used to create keystores for Mule applications?

The method used to create keystores for Mule applications is Java Keytool. This tool is a command-line utility that comes with the Java Development Kit (JDK) and is specifically designed for managing keystores, which store cryptographic keys and certificates used for secure communications.

Java Keytool allows developers to create, import, export, and manage keys and certificates efficiently. By utilizing this tool, a developer can generate self-signed certificates or manage certificates issued by recognized authorities. The ease of use and the ability to integrate with Java applications make it the industry standard for handling keystores in Java-based environments, including Mule applications.

The other methods mentioned do not provide the requisite functionality or security best practices for creating and managing keystores effectively within MuleSoft applications.
