=head1 DESCRIPTION

This command generates a DSA private key from a DSA parameter file
(which will be typically generated by the L<openssl-dsaparam(1)> command).

=head1 OPTIONS

=over 4

=item B<-help>

Print out a usage message.

=item B<-out> I<filename>

Output the key to the specified file. If this argument is not specified then
standard output is used.

=item B<-passout> I<arg>

The passphrase used for the output file.
See L<openssl(1)/Pass Phrase Options>.

=item B<-aes128>, B<-aes192>, B<-aes256>, B<-aria128>, B<-aria192>, B<-aria256>, B<-camellia128>, B<-camellia192>, B<-camellia256>, B<-des>, B<-des3>, B<-idea>

These options encrypt the private key with specified
cipher before outputting it. A pass phrase is prompted for.
If none of these options is specified no encryption is used.

=item B<-verbose>

Print extra details about the operations being performed.

{- $OpenSSL::safe::opt_r_item -}

{- $OpenSSL::safe::opt_engine_item -}

=item I<paramfile>

The DSA parameter file to use. The parameters in this file determine
the size of the private key. DSA parameters can be generated and
examined using the L<openssl-dsaparam(1)> command.

=head1 NOTES

DSA key generation is little more than random number generation so it is
much quicker that RSA key generation for example.
