Returns the names of the cipher suites which could be enabled for use
on an SSL connection.  Normally, only a subset of these will actually
be enabled by default, since this list may include cipher suites which
do not support the mutual authentication of servers and clients, or
which do not protect data confidentiality.  Servers may also need
certain kinds of certificates to use certain cipher suites.
