directly this routine has no effect. Any of the options
that <strong>tls::socket</strong> accepts can be set
using this command, though you should limit your options

exactly the same as the native Tcl <strong>socket</strong>

applicable <a href="#tls::import"><strong>tls:import</strong></a>
options with one additional option:

Protocol Negotiation (ALPN). For example: h2, http/1.1, etc.</dd>

<dd>Specify the certificate authority (CA) file to use.</dd>

<dt><strong>-command</strong> <em>callback</em></dt>
<dd>Callback to invoke at several points during the handshake.

it can allow Tcl scripts to perform their own certificate
validation in place of the default validation provided by
OpenSSL. See <a href="#CALLBACK OPTIONS">CALLBACK OPTIONS</a>
for further discussion.</dd>
<dt><strong>-dhparams </strong><em>filename</em></dt>

structure as the specified <em>channel</em>, and
therefore share callbacks etc.</dd>
<dt><strong>-password</strong> <em>callback</em></dt>
<dd>Callback to invoke when OpenSSL needs to obtain a password,
typically to unlock the private key of a certificate. The
callback should return a string which represents the password
to be used. See <a href="#CALLBACK OPTIONS">CALLBACK OPTIONS</a>
for further discussion.</dd>
<dt><strong>-request </strong><em>bool</em></dt>
<dd>Request a certificate from peer during SSL handshake.
(default is <em>true</em>)</dd>
<dt><strong>-require</strong> <em>bool</em></dt>

If this is set to true, then <strong>-request</strong> must
also be set to true. (default is <em>false</em>)</dd>

<dd>Handshake as server if true, else handshake as
client. (default is <em>false</em>)</dd>
<dt><strong>-servername</strong> <em>host</em></dt>
<dd>Specify server hostname. Only available if the OpenSSL library
the package is linked against supports the TLS hostname extension
for 'Server Name Indication' (SNI). Use to name the logical host
we are talking to and expecting a certificate for.</dd>

<dd>Enable use of SSL v2. (default is <em>false</em>)</dd>
<dt><strong>-ssl3 </strong><em>bool</em></dt>

this routine will throw an error.</dd>
