25 =head1 DESCRIPTION
26
27 This command has been deprecated.
28 The L<openssl-pkeyparam(1)> command should be used instead.
29
30 This command is used to manipulate or generate DSA parameter files.
31
32 DSA parameter generation can be a slow process and as a result the same set of
33 DSA parameters is often used to generate several distinct keys.

35 =head1 OPTIONS
36
37 =over 4
38
39 =item B<-help>
40
41 Print out a usage message.
42
43 =item B<-inform> B<DER>|B<PEM>, B<-outform> B<DER>|B<PEM>
44
45 The input and formats; the default is B<PEM>.
46 See L<openssl(1)/Format Options> for details.
47
48 Parameters are a sequence of B<ASN.1 INTEGER>s: B<p>, B<q>, and B<g>.
49 This is compatible with RFC 2459 B<DSS-Parms> structure.
50
51 =item B<-in> I<filename>
52
53 This specifies the input filename to read parameters from or standard input if
54 this option is not specified. If the I<numbits> parameter is included then
55 this option will be ignored.
56
57 =item B<-out> I<filename>
58
59 This specifies the output filename parameters to. Standard output is used
60 if this option is not present. The output filename should B<not> be the same
61 as the input filename.
62
63 =item B<-noout>
64
65 This option inhibits the output of the encoded version of the parameters.
66
67 =item B<-text>
68
69 This option prints out the DSA parameters in human readable form.
70
71 =item B<-C>
72
73 This option converts the parameters into C code. The parameters can then
74 be loaded by calling the get_dsaXXX() function.
75
76 =item B<-genkey>
77
78 This option will generate a DSA either using the specified or generated
79 parameters.
80
81
82 =item B<-verbose>
83
84 Print extra details about the operations being performed.
85
86 {- $OpenSSL::safe::opt_r_item -}
87
88 {- $OpenSSL::safe::opt_engine_item -}
89
90 =item I<numbits>
91
92 This option specifies that a parameter set should be generated of size
93 I<numbits>. It must be the last option. If this option is included then
94 the input file (if any) is ignored.
