<p>The <strong>gendsa</strong> command generates a DSA private key from a DSA parameter file
|
|
(which will be typically generated by the <strong>openssl dsaparam</strong> command).</p>

<p>These options encrypt the private key with specified

<p>A file or files containing random data used to seed the random number

|
generator.
|

Multiple files can be specified separated by an OS-dependent character.

The separator is <strong>;</strong> for MS-Windows, <strong>,</strong> for OpenVMS, and <strong>:</strong> for

|
all others.</p>

<p>Writes random data to the specified <em>file</em> upon exit.

This can be used with a subsequent <strong>-rand</strong> flag.</p>
|

</dd>
|
|
<dt><strong><a name="engine_id" class="item"><strong>-engine id</strong></a></strong></dt>
|

<dd>
|
|
<p>Specifying an engine (by its unique <strong>id</strong> string) will cause <strong>gendsa</strong>
|
|
to attempt to obtain a functional reference to the specified engine,
|
|
thus initialising it if needed. The engine will then be set as the default
|
|
for all available algorithms.</p>

<p>This option specifies 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 <strong>openssl dsaparam</strong> command.</p>

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