=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<-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<-rand> I<files>
The files containing random data used to seed the random number generator.
Multiple files can be specified separated by an OS-dependent character.
The separator is B<;> for MS-Windows, B<,> for OpenVMS, and B<:> for
all others.
=item B<-writerand> I<file>
Writes random data to the specified I<file> upon exit.
This can be used with a subsequent B<-rand> flag.
=item B<-engine> I<id>
Specifying an engine (by its unique I<id> string) will cause this command
to attempt to obtain a functional reference to the specified engine,
thus initialising it if needed. The engine will then be set as the default
for all available algorithms.
=item B<-verbose>
Print extra details about the operations being performed.
=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.
=back
=head1 NOTES
DSA key generation is little more than random number generation so it is
much quicker that RSA key generation for example.
