=head1 DESCRIPTION
It is intended to simplify the process of certificate creation and management
by the use of some simple options.
+The script is intended as a simple front end for the L<openssl(1)> program for
+use by a beginner. Its behaviour isn't always what is wanted. For more control
+over the behaviour of the certificate commands call the L<openssl(1)> command
+directly.
+
+Most of the filenames mentioned below can be modified by editing the
+B<CA.pl> script.
+
+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:
+
+ perl -S CA.pl
+
+can be used and the B<OPENSSL_CONF> environment variable can be set to point to
+the correct path of the configuration file.
+
=head1 OPTIONS

are created in a directory called F<demoCA> in the current directory.
Uses L<openssl-req(1)> and L<openssl-ca(1)>.
+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 directory if it already exists.

-=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:
-
- perl -S CA.pl
-
-can be used and the B<OPENSSL_CONF> environment variable changed to point to
-the correct path of the configuration file.
-
-The script is intended as a simple front end for the L<openssl(1)> program for
-use by a beginner. Its behaviour isn't always what is wanted. For more control
-over the behaviour of the certificate commands call the L<openssl(1)> command
-directly.
