HP-UX

No.

As I don't use AIX so I don't know if they ship the sources with the OS, or whether SSL module is provided through some special packages or means. But for the general case, Apache needs to be compiled with SSL support if you need HTTPS. You can try to look at the Apache modules directory and check whether any shared library file named 'ssl.so' or similar exists. If the SSL module is compiled static instead you won't see the shared library but that is okay. If so then very likely the Apache is compiled with SSL support.

Probably if you intend to use the OS-packaged Apache and SSL configuration already exists in ssl.conf out of the box, then quite likely the SSL module is already compiled (but not necessarily enabled).

Then you can proceed to ssl.conf configuration as instructed in the Apache documentation or from any external resources.

If your Apache really doesn't have SSL module compiled-in, statically or dynamically, then you need to recompile Apache. Recompiling Apache involves fetching the Apache sources from the Apache Web site and running a configure script inside. On the configure command line you need to add the --enable-ssl option to compile SSL module support. As I said, this is a compilation option, not an Apache configuration directive.
