Update CA.pl podpage, and script
Merge the NOTES section into the relevant parts of the manpage. Add the $EXTRA parameter in consistent places (the end) to call commands. Document that multiple -extra-XXX might be needed.

=head1 DSA CERTIFICATES
|
||||
|
||||
Although the B<CA.pl> creates RSA CAs and requests it is still possible to
|
||||
use it with DSA certificates and requests using the L<openssl-req(1)> command
|
||||
directly. The following example shows the steps that would typically be taken.
|
||||
|
||||
Create some DSA parameters:
|
||||
|
||||
openssl dsaparam -out dsap.pem 1024
|
||||
|
||||
Create a DSA CA certificate and private key:
|
||||
|
||||
openssl req -x509 -newkey dsa:dsap.pem -keyout cacert.pem -out cacert.pem
|
||||
|
||||
Create the CA directories and files:
|
||||
|
||||
CA.pl -newca
|
||||
|
||||
enter a filename (for example, F<cacert.pem>) when prompted for the CA file
|
||||
name.
|
||||
|
||||
Create a DSA certificate request and private key (a different set of parameters
|
||||
can optionally be created first):
|
||||
|
||||
openssl req -out newreq.pem -newkey dsa:dsap.pem
|
||||
|
||||
Sign the request:
|
||||
|
||||
CA.pl -signreq
|
||||
|
||||
=head1 ENVIRONMENT
|
||||
|
||||
The environment variable B<OPENSSL> may be used to specify the name of
|
||||
the OpenSSL program. It can be a full pathname, or a relative one.
|
||||
|
||||
The environment variable B<OPENSSL_CONFIG> may be used to specify a
|
||||
configuration option and value to the B<req> and B<ca> commands invoked by
|
||||
this script. It's value should be the option and pathname, as in
|
||||
C<-config /path/to/conf-file>.
|
||||
|
||||
=head1 NOTES
|
||||
|
||||
Most of the filenames mentioned can be modified by editing the B<CA.pl> script.
|
||||
|
||||
If the F<demoCA> directory already exists then the B<-newca> command will not
|
||||
overwrite it and will do nothing. This can happen if a previous call using
|
||||
the B<-newca> option terminated abnormally. To get the correct behaviour
|
||||
delete the demoCA directory if it already exists.
|
||||
|
||||
Under some environments it may not be possible to run the B<CA.pl> script
|
||||
directly (for example Win32) and the default configuration file location may
|
||||
be wrong. In this case the command:
|
||||

|
||||

||||
can be used and the B<OPENSSL_CONF> environment variable changed to point to

the correct path of the configuration file.
