The B<CA.pl> script is a perl script that supplies the relevant command line
arguments to the B<openssl> command for some common certificate operations.
It is intended to simplify the process of certificate creation and management
by the use of some simple options.

=head1 COMMON OPTIONS

=over 4

=item B<-extra-req> | B<-extra-ca> | B<-extra-pkcs12> | B<-extra-x509> | B<-extra-verify> <extra-params>

The purpose of these parameters is to allow optional parameters to be supplied
to B<openssl> that this command executes. The B<-extra-cmd> are specific to the
option being used and the B<openssl> command getting invoked. For example
when this command invokes B<openssl req> extra parameters can be passed on
with the B<-extra-req> parameter. The
B<openssl> commands being invoked per option are documented below.
Users should consult B<openssl> command documentation for more information.

this option is the same as the B<-signreq> option except it uses the configuration
file section B<v3_ca> and so makes the signed request a valid CA certificate. This
is useful when creating intermediate CA from a root CA.
Extra params are passed on to B<openssl ca> command.
