<H2>DESCRIPTION</H2>
The <B>gendsa</B> command generates a <FONT SIZE="-1">DSA</FONT> private key from a <FONT SIZE="-1">DSA</FONT> parameter file
(which will be typically generated by the <B>openssl dsaparam</B> command).
<A NAME="lbAE">&nbsp;</A>
<H2>OPTIONS</H2>
<DL COMPACT>
<DT id="1"><B>-help</B><DD>
Print out a usage message.
<DT id="2"><B>-out filename</B><DD>
Output the key to the specified file. If this argument is not specified then
standard output is used.
<DT id="3"><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><DD>
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.
<DT id="4"><B>-rand file...</B><DD>
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 <B>;</B> for MS-Windows, <B>,</B> for OpenVMS, and <B>:</B> for
all others.
<DT id="5">[<B>-writerand file</B>]<DD>
Writes random data to the specified <I>file</I> upon exit.
This can be used with a subsequent <B>-rand</B> flag.
<DT id="6"><B>-engine id</B><DD>
Specifying an engine (by its unique <B>id</B> string) will cause <B>gendsa</B>
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.
<DT id="7"><B>paramfile</B><DD>
This option specifies the <FONT SIZE="-1">DSA</FONT> parameter file to use. The parameters in this
file determine the size of the private key. <FONT SIZE="-1">DSA</FONT> parameters can be generated
and examined using the <B>openssl dsaparam</B> command.
</DL>
<A NAME="lbAF">&nbsp;</A>
<H2>NOTES</H2>
<FONT SIZE="-1">DSA</FONT> key generation is little more than random number generation so it is
much quicker that <FONT SIZE="-1">RSA</FONT> key generation for example.
