.SH DESCRIPTION
.IX Header "DESCRIPTION"
This command generates a DSA private key from a DSA 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
.IX Item "-aes128, -aes192, -aes256, -aria128, -aria192, -aria256, -camellia128, -camellia192, -camellia256, -des, -des3, -idea"
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.
.IP \fB\-verbose\fR 4
.IX Item "-verbose"
Print extra details about the operations being performed.
.IP \fB\-quiet\fR 4
.IX Item "-quiet"
Print fewer details about the operations being performed, which may
be handy during batch scripts and pipelines.
.IP "\fB\-rand\fR \fIfiles\fR, \fB\-writerand\fR \fIfile\fR" 4
.IX Item "-rand files, -writerand file"
See "Random State Options" in \fBopenssl\fR\|(1) for details.
.IP "\fB\-engine\fR \fIid\fR" 4
.IX Item "-engine id"
See "Engine Options" in \fBopenssl\fR\|(1).
This option is deprecated.
.IP \fIparamfile\fR 4
.IX Item "paramfile"
The DSA parameter file to use. The parameters in this file determine
the size of the private key. DSA parameters can be generated and
examined using the \fBopenssl\-dsaparam\fR\|(1) command.
.IP "\fB\-provider\fR \fIname\fR" 4
.IX Item "-provider name"
.PD 0
.IP "\fB\-provider\-path\fR \fIpath\fR" 4
.IX Item "-provider-path path"
.IP "\fB\-propquery\fR \fIpropq\fR" 4
.IX Item "-propquery propq"
.PD
See "Provider Options" in \fBopenssl\fR\|(1), \fBprovider\fR\|(7), and \fBproperty\fR\|(7).
.SH NOTES
.IX Header "NOTES"
DSA key generation is little more than random number generation so it is
much quicker that RSA key generation for example.
