command. In such cases <strong>tls::import</strong> should not be
used directly.</p>

<dd>This routine sets the default options used by <strong>tls::socket</strong>
and is <em>optional</em>. If you call <strong>tls::import</strong>
<dd>Optional function to set the default options used by
<strong>tls::socket</strong>. If you call <strong>tls::import</strong>
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
to only TLS related ones.</dd>

<dd>This is a helper function that utilizes the underlying
commands (<strong>tls::import</strong>). It behaves
exactly the same as the native Tcl <strong>socket</strong>
command except that the options can include any of the
applicable <a href="#tls::import"><strong>tls:import</strong></a>
options with one additional option:
<blockquote>

socket, but must provide bi-directional flow. Also
setting session parameters for SSL handshake.</dd>

<dd>List of protocols to offer during Application-Layer
Protocol Negotiation (ALPN). For example: h2, http/1.1, etc.</dd>
<dt><strong>-cadir</strong> <em>dir</em></dt>
<dd>Specify the directory containing the CA certificates. The

compile time. This can be overridden via the <b>SSL_CERT_DIR</b>
environment variable.</dd>
<dt><strong>-cafile </strong><em>filename</em></dt>
<dd>Specify the certificate authority (CA) file to use.</dd>

encoded binary value (X.509 DER).</dd>
<dt><strong>-cipher</strong> <em>string</em></dt>

of ciphers or cipher suites. Cipher suites can be combined
using the <b>+</b> character. Prefixes can be used to permanently
remove ("!"), delete ("-"), or move a cypher to the end of
the list ("+"). Keywords <b>@STRENGTH</b> (sort by algorithm
key length), <b>@SECLEVEL=</b><i>n</i> (set security level to
n), and <b>DEFAULT</b> (use default cipher list, at start only)

separated list of cipher suite names. (TLS 1.3 only)</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>

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

to be used. See <a href="#CALLBACK OPTIONS">CALLBACK OPTIONS</a>

<dd>Request a certificate from peer during SSL handshake.
(default is <em>true</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>
<dt><strong>-ssl2</strong> <em>bool</em></dt>
<dd>Enable use of SSL v2. (default is <em>false</em>)</dd>
<dt><strong>-ssl3 </strong><em>bool</em></dt>

<dt><a name="tls::handshake"><strong>tls::handshake</strong> <em>channel</em></a></dt>
<dd>Forces handshake to take place, and returns 0 if
handshake is still in progress (non-blocking), or 1 if
the handshake was successful. If the handshake failed
this routine will throw an error.</dd>

<dt><a name="tls::status"><strong>tls::status</strong>
<em>?-local? channel</em></a></dt>
<dd>Returns the current security status of an SSL channel. The
<dd>Returns the current certificate status of an SSL channel. The
result is a list of key-value pairs describing the
connected peer. If the result is an empty list then the
SSL handshake has not yet completed.
If <em>-local</em> is given, then the certificate information
is the one used locally.</dd>
