=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<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.
