=head1 DESCRIPTION
|
||
|
|
|
||
|
|
This command is used to manipulate or generate DSA parameter files.
|
||
|
|
|
||
|
|
=head1 OPTIONS
|
||
|
|
|
||
|
|
=over 4
|
||
|
|
|
||
|
|
=item B<-inform DER|PEM>
|
||
|
|
|
||
|
|
This specifies the input format. The B<DER> option uses an ASN1 DER encoded
|
||
|
|
form compatible with RFC2459 (PKIX) DSS-Parms that is a SEQUENCE consisting
|
||
|
|
of p, q and g respectively. The PEM form is the default format: it consists
|
||
|
|
of the B<DER> format base64 encoded with additional header and footer lines.
|
||
|
|
|
||
|
|
=item B<-outform DER|PEM>
|
||
|
|
|
||
|
|
This specifies the output format, the options have the same meaning as the
|
||
|
|
B<-inform> option.
|
||
|
|
|
||
|
|
=item B<-in filename>
|
||
|
|
|
||
|
|
This specifies the input filename to read parameters from or standard input if
|
||
|
|
this option is not specified. If the B<numbits> parameter is included then
|
||
|
|
this option will be ignored.
|
||
|
|
|
||
|
|
=item B<-out filename>
|
||
|
|
|
||
|
|
This specifies the output filename parameters to. Standard output is used
|
||
|
|
if this option is not present. The output filename should B<not> be the same
|
||
|
|
as the input filename.
|
||
|
|
|
||
|
|
=item B<-noout>
|
||
|
|
|
||
|
|
this option inhibits the output of the encoded version of the parameters.
|
||
|
|
|
||
|
|
=item B<-text>
|
||
|
|
|
||
|
|
this option prints out the DSA parameters in human readable form.
|
||
|
|
|
||
|
|
=item B<-C>
|
||
|
|
|
||
|
|
this option converts the parameters into C code. The parameters can then
|
||
|
|
be loaded by calling the B<get_dsaXXX()> function.
|
||
|
|
|
||
|
|
=item B<-genkey>
|
||
|
|
|
||
|
|
this option will generate a DSA either using the specified or generated
|
||
|
|
parameters.
|
||
|
|
|
||
|
|
=item B<-rand file:file>
|
||
|
|
|
||
|
|
a file or files containing random data used to seed the random number
|
||
|
|
generator. Multiple files can be specified separated by B<:>.
|
||
|
|
|
||
|
|
=item B<numbits>
|
||
|
|
|
||
|
|
this option specifies that a parameter set should be generated of size
|
||
|
|
B<numbits>. It must be the last option. If this option is included then
|
||
|
|
the input file (if any) is ignored.

=head1 NOTES
|
||
|
|
|
||
|
|
DSA parameter generation is a slow process and as a result the same set of
|
||
|
|
DSA parameters is often used to generate several distinct keys.
