+This is the same example as seen in hello_security in the examples in the 
+rti_workspace. The other APIs examples are available when RTI Connext is

+
+In this example, the publisher application sends a message of "Hello World" with
+a number to indicate which sample it is. This number increments by one and by
+default will go until the user stops the programs. By default, the messages are 
+sent using ecdsa but can be set to rsa or ecdsa secp384r1 by providing an 
+argument at run time.
