The Dynamic Data Masking installation contains a .jar file that you must save on the client machine. The .jar file contains a Java agent, a transformer that intercepts the method calls of JDBC objects, and proxy classes for JDBC classes. You can find the .jar file in the following location:

<Dynamic Data Masking installation>\Wrappers\jdbc\GenericJDBC.jar

You must perform additional configuration steps based on the client and operating system.
