\`configure' configures tls 1.8.0 to adapt to many kinds of systems.

Usage: $0 [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE.  See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:
  -h, --help              display this help and exit
      --help=short        display options specific to this package
      --help=recursive    display the short help of all the included packages
  -V, --version           display version information and exit
  -q, --quiet, --silent   do not print \`checking ...' messages
      --cache-file=FILE   cache test results in FILE [disabled]
  -C, --config-cache      alias for \`--cache-file=config.cache'
  -n, --no-create         do not create output files
      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

Installation directories:
  --prefix=PREFIX         install architecture-independent files in PREFIX
                          [$ac_default_prefix]
  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                          [PREFIX]

By default, \`make install' will install all the files in
\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
an installation prefix other than \`$ac_default_prefix' using \`--prefix',
for instance \`--prefix=\$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:
  --bindir=DIR            user executables [EPREFIX/bin]
  --sbindir=DIR           system admin executables [EPREFIX/sbin]
  --libexecdir=DIR        program executables [EPREFIX/libexec]

  TCLTLS_SSL_CFLAGS
              C compiler flags for OpenSSL or LibreSSL
  TCLTLS_SSL_INCLUDES
              C compiler include paths for OpenSSL or LibreSSL
  TCLTLS_SSL_LIBS
              libraries to pass to the linker for OpenSSL or LibreSSL

Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.

Report bugs to the package provider.

<h3><a name="DESCRIPTION">DESCRIPTION</a></h3>

<p>This extension provides TCL script access to secure socket communications
using the Transport Layer Security (TLS) protocol. It provides a generic
binding to <a href="http://www.openssl.org/">OpenSSL</a>, utilizing the
<strong>Tcl_StackChannel</strong> API in Tcl 8.4 and higher.
These sockets behave exactly the same as channels created using the built-in
<strong>socket</strong> command, along with additional options for controlling
the SSL session.
</p>



<h3><a name="COMMANDS">COMMANDS</a></h3>

<p>Typically one would use the <strong>tls::socket </strong>command
which provides compatibility with the native Tcl <strong>socket</strong>
command. In such cases <strong>tls::import</strong> should not be
used directly.</p>

<dl>
    <dt><a name="tls::init"><b>tls::init </b><i>?options?</i></a></dt>
    <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>
    <dt>&nbsp;</dt>
    <dt><a name="tls::socket"><b>tls::socket </b><em>?options?
	host port</em></a></dt>
    <dt><b>tls::socket</b><em> ?-server command? ?options? port</em></dt>
    <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 the options can also include any of the
	applicable <a href="#tls::import"><strong>tls:import</strong></a>
	options with one additional option:</dd>
<blockquote>
    <dl>
	<dt><strong>-autoservername</strong> <em>bool</em></dt>
	<dd>Automatically set the -servername argument to the <em>host</em>
	    argument (default is <em>false</em>).</dd>
    </dl>
</blockquote>

    <dt><a name="tls::import"><b>tls::import </b><i>channel
	?options?</i></a></dt>
    <dd>Add SSL/TLS encryption to a regular Tcl channel. It need
	not be a socket, but must provide bi-directional flow. Also
	set session parameters for SSL handshake.</dd>

<blockquote>
    <dl>
	<dt><strong>-alpn</strong> <em>list</em></dt>
	<dd>List of protocols to offer during Application-Layer
	    Protocol Negotiation (ALPN). For example: <em>h2</em> and
	    <em>http/1.1</em>, but not <em>h3</em> or <em>quic</em>.</dd>
	<dt><strong>-cadir</strong> <em>dir</em></dt>

	<dd>Set the CA certificates path. 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>Set the certificate authority (CA) certificates file. The default
	    is the cert.pem file in the OpsnSSL directory. This can also be
	    overridden via the <b>SSL_CERT_FILE</b> environment variable.</dd>
	<dt><strong>-certfile</strong> <em>filename</em></dt>
	<dd>Specify the filename with the certificate to use.</dd>

	<dt><strong>-cert</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. Ciphers 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>
	<dt><strong>-ciphersuites</strong> <em>string</em></dt>
	<dd>List of cipher suites to use. String is a colon (":")
	    separated list of cipher suite names. (TLS 1.3 only)</dd>
	<dt><strong>-command</strong> <em>callback</em></dt>
	<dd>Callback command to invoke at several points during the handshake.
	    This is used to pass errors and tracing information, and
	    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>
	<dt><strong>-keyfile</strong> <em>filename</em></dt>
	<dd>Specify the private key file. (default is
	    value of -certfile)</dd>
	<dt><strong>-key</strong> <em>filename</em></dt>
	<dd>Specify the private key to use as a DER encoded value (PKCS#1 DER)</dd>
	<dt><strong>-model</strong> <em>channel</em></dt>
	<dd>Force this channel to share the same <em><strong>SSL_CTX</strong></em>
	    structure as the specified <em>channel</em>, and
	    therefore share callbacks etc.</dd>
	<dt><strong>-password</strong> <em>callback</em></dt>
	<dd>Callback command to invoke when OpenSSL needs to obtain a password.
	    Typically used 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>-post_handshake</strong> <em>bool</em></dt>
	<dd>Allow post-handshake ticket updates.</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>
	<dd>Require a valid certificate from peer during SSL handshake.
	    If this is set to true, then <strong>-request</strong> must
	    also be set to true and a either a -cadir, -cafile, or platform
	    default must be provided in order to validate against.
	    (default is <em>false</em>)</dd>
	<dt><strong>-security_level</strong> <em>integer</em></dt>
	<dd>Set security level. Must be 0 to 5. The security level affects
	    the 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>Set to act as a server and respond with a server handshake when
	    a client connects and provides a client handshake.
	    (default is <em>false</em>)</dd>
	<dt><strong>-servername</strong> <em>host</em></dt>
	<dd>Specify server's hostname. Used to set the TLS 'Server Name
	    Indication' (SNI) extension. Set to the expected servername
	    in the server's certificate or one of the subjectAltName
	    alternates.</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>
	<dt><strong>-ssl3 </strong><em>bool</em></dt>
	<dd>Enable use of SSL v3. (default is <em>false</em>)</dd>
	<dt>-<strong>tls1</strong> <em>bool</em></dt>
	<dd>Enable use of TLS v1. (default is <em>true</em>)</dd>

	<dt>-<strong>tls1.3</strong> <em>bool</em></dt>
	<dd>Enable use of TLS v1.3 (default is <em>true</em>)</dd>
