<appsummary>The SSL application provides secure communication over
sockets.</appsummary>
<section>
<title>DEPENDENCIES</title>
<p>The ssl application uses the Erlang applications public_key and
crypto to handle public keys and encryption, hence these
applications needs to be loaded for the ssl application to work. In
an embedded environment that means they need to be started with
application:start/[1,2] before the ssl application is started.
</p>
</section>
<section>
<title>ENVIRONMENT</title>
<p>The following application environment configuration parameters
are defined for the SSL application. Refer to application(3) for
more information about configuration parameters.
</p>
<p>Note that the environment parameters can be set on the command line,
for instance,</p>
<p><c>erl ... -ssl protocol_version '[sslv3, tlsv1]' ...</c>.
</p>
<taglist>
<tag><c><![CDATA[protocol_version = [sslv3|tlsv1] <optional>]]></c>.</tag>
<item>
<p>Protocol that will be supported by started clients and
servers. If this option is not set it will default to all
protocols currently supported by the erlang ssl application.
Note that this option may be overridden by the version option
to ssl:connect/[2,3] and ssl:listen/2.
</p>
</item>
<tag><c><![CDATA[session_lifetime = integer() <optional>]]></c></tag>
<item>
<p>The lifetime of session data in seconds.
</p>
</item>
<tag><c><![CDATA[session_cb = atom() <optional>]]></c></tag>
<item>
<p>

</p>
</item>
<tag><c><![CDATA[session_cb_init_args = list() <optional>]]></c></tag>
<item>
