18# The purpose of this test is to verify that we have actually gone
19# through and called the rekey functions in the implementation of the
20# arc4random code that we have. To do that, we look at the actual part
21# of the code that does generation. In this case, the function
22# arc4_rekey() which is a private function as part of libc.
