Initially, the manual page entry for the 'openssl cmd' command used to be available at 'cmd(1)'. Later, the aliases 'openssl-cmd(1)' was introduced, which made it easier to group the openssl commands using the 'apropos(1)' command or the shell's tab completion. In order to reduce cluttering of the global manual page namespace, the manual page entries without the 'openssl-' prefix have been deprecated in OpenSSL 3.0 and will be removed in OpenSSL 4.0.

=head1 DESCRIPTION
|
|
|
|
The B<gendsa> command generates a DSA private key from a DSA parameter file
|
|
(which will be typically generated by the B<openssl dsaparam> command).
|
|
|
|
=head1 OPTIONS
|
|
|
|
=over 4
|
|
|
|
=item B<-help>
|
|
|
|
Print out a usage message.
|
|
|
|
=item B<-out 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 file...>
|
|
|
|
A file or 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 file>]
|
|
|
|
Writes random data to the specified I<file> upon exit.
|
|
This can be used with a subsequent B<-rand> flag.
|
|
|
|
=item B<-engine id>
|
|
|
|
Specifying an engine (by its unique B<id> string) will cause B<gendsa>
|
|
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 B<paramfile>
|
|
|
|
This option specifies 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 B<openssl dsaparam> command.

|
=head1 NOTES
|
|
|
|
DSA key generation is little more than random number generation so it is
|
|
much quicker that RSA key generation for example.
