<p>openssl-gendsa - generate a DSA private key from a set of parameters</p>

<h1 id="SYNOPSIS">SYNOPSIS</h1>

<h1 id="DESCRIPTION">DESCRIPTION</h1>

<p>This command generates a DSA private key from a DSA parameter file (which will be typically generated by the <a href="../man1/openssl-dsaparam.html">openssl-dsaparam(1)</a> command).</p>

<h1 id="OPTIONS">OPTIONS</h1>

<dl>

<dt id="help"><b>-help</b></dt>
<dd>

<p>Print out a usage message.</p>

</dd>
<dt id="out-filename"><b>-out</b> <i>filename</i></dt>
<dd>

<p>Output the key to the specified file. If this argument is not specified then standard output is used.</p>

</dd>
<dt id="passout-arg"><b>-passout</b> <i>arg</i></dt>
<dd>

<p>The passphrase used for the output file. See <a href="../man1/openssl-passphrase-options.html">openssl-passphrase-options(1)</a>.</p>

</dd>
<dt id="aes128--aes192--aes256--aria128--aria192--aria256--camellia128--camellia192--camellia256--des--des3--idea"><b>-aes128</b>, <b>-aes192</b>, <b>-aes256</b>, <b>-aria128</b>, <b>-aria192</b>, <b>-aria256</b>, <b>-camellia128</b>, <b>-camellia192</b>, <b>-camellia256</b>, <b>-des</b>, <b>-des3</b>, <b>-idea</b></dt>
<dd>

<p>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.</p>

<p>Note that all options must be given before the <i>paramfile</i> argument.</p>

</dd>
<dt id="verbose"><b>-verbose</b></dt>
<dd>

<p>Print extra details about the operations being performed.</p>

</dd>
<dt id="quiet"><b>-quiet</b></dt>
<dd>

<p>Print fewer details about the operations being performed, which may be handy during batch scripts and pipelines.</p>

</dd>
<dt id="rand-files--writerand-file"><b>-rand</b> <i>files</i>, <b>-writerand</b> <i>file</i></dt>
<dd>

<p>See <a href="../man1/openssl.html">&quot;Random State Options&quot; in openssl(1)</a> for details.</p>

</dd>
<dt id="engine-id"><b>-engine</b> <i>id</i></dt>
<dd>

<p>See <a href="../man1/openssl.html">&quot;Engine Options&quot; in openssl(1)</a>. This option is deprecated.</p>

</dd>
<dt id="paramfile"><i>paramfile</i></dt>
<dd>

<p>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 <a href="../man1/openssl-dsaparam.html">openssl-dsaparam(1)</a> command.</p>

</dd>

<dd>

</dd>

<h1 id="NOTES">NOTES</h1>

<p>DSA key generation is little more than random number generation so it is much quicker that RSA key generation for example.</p>
