| |
| =head1 DESCRIPTION |
| |
| This command is used to manipulate or generate DSA parameter files. |
| |
| DSA parameter generation can be a slow process and as a result the same set of |
| DSA parameters is often used to generate several distinct keys. |
| |
| =head1 OPTIONS |
| |
| =over 4 |
| |
| =item B<-help> |
| |
| Print out a usage message. |
| |
| =item B<-inform> B<DER>|B<PEM> |
| |
| The DSA parameters input format; unspecified by default. |
| See L<openssl-format-options(1)> for details. |
| |
| =item B<-outform> B<DER>|B<PEM> |
| |
| The DSA parameters output format; the default is B<PEM>. |
| See L<openssl-format-options(1)> for details. |
| |
| Parameters are a sequence of B<ASN.1 INTEGER>s: B<p>, B<q>, and B<g>. |
| This is compatible with RFC 2459 B<DSS-Parms> structure. |
| |
| =item B<-in> I<filename> |
| |
| This specifies the input filename to read parameters from or standard input if |
| this option is not specified. If the I<numbits> parameter is included then |
| this option will be ignored. |
| |
| =item B<-out> I<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<-genkey> |
| |
| This option will generate a DSA either using the specified or generated |
| parameters. |
| |
| |
| =item B<-verbose> |
| |
| Print extra details about the operations being performed. |
| |
| =item B<-quiet> |
| |
| Print fewer details about the operations being performed, which may |
| be handy during batch scripts and pipelines. |
| |
| {- $OpenSSL::safe::opt_r_item -} |
| |
| {- $OpenSSL::safe::opt_engine_item -} |
| |
| =item I<numbits> |
| |
| This option specifies that a parameter set should be generated of size |
| I<numbits>. It must be the last option. If this option is included then |
| the input file (if any) is ignored. |
| |
| {- $OpenSSL::safe::opt_provider_item -} |
