<dl>
<dt><strong>-alpn</strong> <em>list</em></dt>
<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
default directory is platform specific and can be set at
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>
<dt><strong>-certfile</strong> <em>filename</em></dt>

<dd>Specify the contents of a certificate to use, as a DER
encoded binary value (X.509 DER).</dd>
<dt><strong>-cipher</strong> <em>string</em></dt>
<dd>List of ciphers to use. String is a colon (":") separated list
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)
can also be specified. See OpenSSL documentation for the full
list of valid values. (TLS 1.2 and earlier only)</dd>

separated list of cipher suite names. (TLS 1.3 only)</dd>
<dt><strong>-command</strong> <em>callback</em></dt>

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>
<dd>Specify the Diffie-Hellman parameters file.</dd>

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>

If this is set to true, then <strong>-request</strong> must
also be set to true. (default is <em>false</em>)</dd>
<dt><strong>-securitylevel</strong> <em>integer</em></dt>
<dd>Set security level. Must be 0 to 5. The security level affects
cipher suite encryption algorithms, supported ECC curves,
supported signature algorithms, DH parameter sizes, certificate
key sizes and signature algorithms. The default is 1.
Level 3 and higher disable support for session tickets and only
accept cipher suites that provide forward secrecy.</dd>
<dt><strong>-server</strong> <em>bool</em></dt>
<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>-session_id</strong> <em>string</em></dt>
<dd>Session id to resume session.</dd>
<dt><strong>-ssl2</strong> <em>bool</em></dt>
<dd>Enable use of SSL v2. (default is <em>false</em>)</dd>
