(#10377) Add spec test for --enc-ssl option
(#10377) Add spec test for --enc-ssl option

This patch adds spec test behavior coverage for the --enc-ssl command
line option.  Without this test, we don't have any test coverage for
--enc-ssl.

The test fails as expected if the option is removed or renamed in the
action.
