.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This command generates a \s-1DSA\s0 private key from a \s-1DSA\s0 parameter file
(which will be typically generated by the \fBopenssl\-dsaparam\fR\|(1) command).
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-help\fR" 4
.IX Item "-help"
Print out a usage message.
.IP "\fB\-out\fR \fIfilename\fR" 4
.IX Item "-out filename"
Output the key to the specified file. If this argument is not specified then
standard output is used.
.IP "\fB\-passout\fR \fIarg\fR" 4
.IX Item "-passout arg"
The passphrase used for the output file.
See \fBopenssl\-passphrase\-options\fR\|(1).
.IP "\fB\-aes128\fR, \fB\-aes192\fR, \fB\-aes256\fR, \fB\-aria128\fR, \fB\-aria192\fR, \fB\-aria256\fR, \fB\-camellia128\fR, \fB\-camellia192\fR, \fB\-camellia256\fR, \fB\-des\fR, \fB\-des3\fR, \fB\-idea\fR" 4

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.
.Sp
Note that all options must be given before the \fIparamfile\fR argument.
Otherwise they are ignored.
.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"Random State Options\*(R" in \fBopenssl\fR\|(1) for details.
.IP "\fB\-engine\fR \fIid\fR" 4
.IX Item "-engine id"
See \*(L"Engine Options\*(R" in \fBopenssl\fR\|(1).
This option is deprecated.
.IP "\fIparamfile\fR" 4
.IX Item "paramfile"
The \s-1DSA\s0 parameter file to use. The parameters in this file determine
the size of the private key. \s-1DSA\s0 parameters can be generated and
examined using the \fBopenssl\-dsaparam\fR\|(1) command.

.PD
See \*(L"Provider Options\*(R" in \fBopenssl\fR\|(1), \fBprovider\fR\|(7), and \fBproperty\fR\|(7).
.SH "NOTES"
.IX Header "NOTES"
\&\s-1DSA\s0 key generation is little more than random number generation so it is
much quicker that \s-1RSA\s0 key generation for example.
