This command has been deprecated.
|
|
The \fIopenssl\-pkeyparam\fR\|(1) command should be used instead.
|
|
.PP
|
|
This command is used to manipulate or generate \s-1DSA\s0 parameter files.
|
|
.PP
|
|
\&\s-1DSA\s0 parameter generation can be a slow process and as a result the same set of
|
|
\&\s-1DSA\s0 parameters is often used to generate several distinct keys.

|
|
.IP "\fB\-help\fR" 4
|
|
.IX Item "-help"
|
|

|
.IP "\fB\-inform\fR \fB\s-1DER\s0\fR|\fB\s-1PEM\s0\fR, \fB\-outform\fR \fB\s-1DER\s0\fR|\fB\s-1PEM\s0\fR" 4
|
|
.IX Item "-inform DER|PEM, -outform DER|PEM"
|
|
The input and formats; the default is \fB\s-1PEM\s0\fR.
|
|
See \*(L"Format Options\*(R" in \fIopenssl\fR\|(1) for details.
|
|
.Sp
|
|
Parameters are a sequence of \fB\s-1ASN\s0.1 \s-1INTEGER\s0\fRs: \fBp\fR, \fBq\fR, and \fBg\fR.
|
|
This is compatible with \s-1RFC\s0 2459 \fBDSS-Parms\fR structure.
|
|
.IP "\fB\-in\fR \fIfilename\fR" 4
|
|
.IX Item "-in filename"
|
|
This specifies the input filename to read parameters from or standard input if
|
|
this option is not specified. If the \fInumbits\fR parameter is included then
|
|
this option will be ignored.
|
|
.IP "\fB\-out\fR \fIfilename\fR" 4
|
|
.IX Item "-out filename"
|
|
This specifies the output filename parameters to. Standard output is used
|
|
if this option is not present. The output filename should \fBnot\fR be the same
|
|
as the input filename.
|
|
.IP "\fB\-noout\fR" 4
|
|
.IX Item "-noout"
|
|
This option inhibits the output of the encoded version of the parameters.
|
|
.IP "\fB\-text\fR" 4
|
|
.IX Item "-text"
|
|
This option prints out the \s-1DSA\s0 parameters in human readable form.
|
|
.IP "\fB\-C\fR" 4
|
|
.IX Item "-C"
|
|
This option converts the parameters into C code. The parameters can then
|
|
be loaded by calling the \fIget_dsaXXX()\fR function.
|
|
.IP "\fB\-genkey\fR" 4
|
|
.IX Item "-genkey"
|
|
This option will generate a \s-1DSA\s0 either using the specified or generated
|
|
parameters.
|
|
.IP "\fB\-verbose\fR" 4
|
|
.IX Item "-verbose"
|
|
Print extra details about the operations being performed.
|
|
.IP "\fB\-rand\fR \fIfiles\fR, \fB\-writerand\fR \fIfile\fR" 4
|
|
.IX Item "-rand files, -writerand file"

See \*(L"Engine Options\*(R" in \fIopenssl\fR\|(1).
|
|
.IP "\fInumbits\fR" 4
|
|
.IX Item "numbits"
|
|
This option specifies that a parameter set should be generated of size
|
|
\&\fInumbits\fR. It must be the last option. If this option is included then
|
