<p>openssl-engine - load and query engines</p>

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

<p><b>openssl engine</b> [<b>-help</b>] [<b>-v</b>] [<b>-vv</b>] [<b>-vvv</b>] [<b>-vvvv</b>] [<b>-c</b>] [<b>-t</b>] [<b>-tt</b>] [<b>-pre</b> <i>command</i>] ... [<b>-post</b> <i>command</i>] ... [<i>engine</i> ...]</p>

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

<p>This command has been deprecated. Providers should be used instead of engines.</p>

<p>This command is used to query the status and capabilities of the specified <i>engine</i>s. Engines may be specified before and after all other command-line flags. Only those specified are queried.</p>

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

<dl>

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

<p>Display an option summary.</p>

</dd>
<dt id="v--vv--vvv--vvvv"><b>-v</b> <b>-vv</b> <b>-vvv</b> <b>-vvvv</b></dt>
<dd>

<p>Provides information about each specified engine. The first flag lists all the possible run-time control commands; the second adds a description of each command; the third adds the input flags, and the final option adds the internal input flags.</p>

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

<p>Lists the capabilities of each engine.</p>

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

<p>Tests if each specified engine is available, and displays the answer.</p>

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

<p>Displays an error trace for any unavailable engine.</p>

</dd>
<dt id="pre-command"><b>-pre</b> <i>command</i></dt>
<dd>

</dd>
<dt id="post-command"><b>-post</b> <i>command</i></dt>
<dd>

<p>Command-line configuration of engines. The <b>-pre</b> command is given to the engine before it is loaded and the <b>-post</b> command is given after the engine is loaded. The <i>command</i> is of the form <i>cmd</i>:<i>val</i> where <i>cmd</i> is the command, and <i>val</i> is the value for the command. See the example below.</p>

<p>These two options are cumulative, so they may be given more than once in the same command.</p>

</dd>
</dl>

<h1 id="EXAMPLES">EXAMPLES</h1>

<p>To list all the commands available to a dynamic engine:</p>

<pre><code>$ openssl engine -t -tt -vvvv dynamic

     [ unavailable ]
     SO_PATH: Specifies the path to the new ENGINE shared library
          (input flags): STRING

          (input flags): NUMERIC
     ID: Specifies an ENGINE id name for loading
