	with 8.2+ and dynamically adjust to the version of Tcl it was
	loaded into.  TLS will fail the test suite with Tcl 8.2-8.3.1.

	* tests/all.tcl: added catch around ::tcltest::normalizePath
	because it doesn't exist in pre-8.3 tcltest.

	* tests/simpleClient.tcl: 
	* tests/simpleServer.tcl: added simple client/server test scripts
	that use test certs and can do simple stress tests.

\`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]

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

<p>The following options are used by the cryptography commands.</p>
<br>
<h4>Cryptographic Options</h4>

<dl>
    <dt><a name="-aad_data"><strong>-aad_data</strong> <em>string</em></a></dt>
    <dd>Additional Authenticated Data (AAD).</dd>
</dl>

<dl>
    <dt><a name="-cipher"><strong>-cipher</strong> <em>name</em></a></dt>
    <dd>Name of symmetric cipher to use. Used by encrypt/decrypt command
    and CMAC &amp; GMAC hash algorithms. For CMAC, it must be one of
    <b>AES-128-CBC</b>, <b>AES-192-CBC</b>, <b>AES-256-CBC</b>, or
    <b>DES-EDE3-CBC</b>. For GMAC it should be a GCM mode cipher (e.g.
    AES-128-GCM). See <a href="#tls::ciphers"><b>tls::ciphers</b></a>
    command for the valid values. Only CCM and GCM modes (also  known as Authenticated
    Encryption with Associated Data (AEAD) modes) provide both confidentially
    and integrity protection.</dd>
</dl>

<dl>
    <dt><a name="-digest"><strong>-digest</strong> <em>name</em></a></dt>
    <dt><a name="-hash"><strong>-hash</strong> <em>name</em></a></dt>
    <dd>Name of hash function (aka message digest) to use.
    See <a href="#tls::digests"><b>tls::digests</b></a> command for the valid values.</dd>
</dl>

<dl>
    <dt><a name="-info"><strong>-info</strong> <em>string</em></a></dt>
    <dd>Optional context and application specific information. Can be a binary
    or text string. Max length is 1024 bytes for OpenSSL 1.1 and 2048 bytes for 3.0.</dd>
</dl>

<dl>
    <dt><a name="-iterations"><strong>-iterations</strong> <em>count</em></a></dt>
    <dd>Number (integer &gt; 0) of iterations to use in deriving the encryption
    key. Default is 2048. Some <a href="#KDF"><b>KDF</b></a> implementations
    require an iteration count.</dd>
</dl>

<dl>
    <dt><a name="-iv"><strong>-iv</strong> <em>string</em></a></dt>
    <dd>Initialization vector (IV) to use. Required for some ciphers and GMAC.
    Other MACs use a fixed IV. Cipher modes CBC, CFB, and OFB all need an IV,
    while ECB and CTR modes do not. A new, random IV should (must for OFB) be
    created for each use. Think of the IV as a nonce
    (number used once), it's public but random and unpredictable. See the
   <a href="#tls::cipher"><b>tls::cipher</b></a> for iv_length and when
   required (length > 0). Max is 16 bytes. If not set, it will default to \x00
   fill data.</dd>
</dl>

<dl>
    <dt><a name="-key"><strong>-key</strong> <em>string</em></a></dt>
    <dd>Encryption key to use for cryptography function. Can be a binary or
    text string. Longer keys provide better protection. Used by ciphers, HMAC,
    some CMAC, and some KDF implementations. If the length of the key is &lt;
    <b>key_length</b> it will be padded. Max is 64 bytes. If &gt; key_length,
    it will be rejected.
    See the <a href="#tls::cipher"><b>tls::cipher</b></a> for key_length.</dd>
</dl>

<dl>
    <dt><a name="-mac"><strong>-mac</strong> <em>name</em></a></dt>
    <dd>Name of Message Authentication Code (MAC) to use.
    See <a href="#tls::mac"><b>tls::macs</b></a> command for the valid values.</dd>
</dl>

<dl>
    <dt><a name="-padding"><strong>-padding</strong> <em>boolean</em></a></dt>
    <dd>Specifies whether to use PKCS#7 padding or not for block ciphers. If
    true, 1 to block size number of pad bytes will be added to the output to
    pad to the next block size. Default is true.</dd>
</dl>

<dl>
    <dt><a name="-password"><strong>-password</strong> <em>string</em></a></dt>
    <dd>Password to use for some KDF functions. If not specified, the default
    value is used. Can be a binary or text string. For KDF commands, this is
    the same as the <b>-key</b> option.</dd>
</dl>

<dl>
    <dt><a name="-properties"><strong>-properties</strong> <em>list</em></a></dt>
    <dd>List of additional properties to pass to cryptographic function.</dd>
</dl>

<dl>
    <dt><a name="-salt"><strong>-salt</strong> <em>string</em></a></dt>
    <dd>Specifies salt value to use when encrypting data. Can be a binary or
    text string. Default is to use a string of \0's. It is best to use a
    uniquely and randomly generated value. This option is used by BLAKE2 MAC
    and some KDF implementations use a non-secret unique cryptographic salt.</dd>
</dl>

<dl>
    <dt><a name="-length"><strong>-length</strong> <em>integer</em></a></dt>
    <dt><a name="-size"><strong>-size</strong> <em>integer</em></a></dt>
    <dd>Set the output length in bytes. Used by KDFs, KMAC128 and KMAC256 MACs,
    and SHAKE128 and SHAKE256 XOF hashes. The default length for KMAC128 is 32
    bytes and KMAC256 is 64 bytes. The default length for SHAKE128 is 16 bytes
    and SHAKE256 is 32 bytes.</dd>
</dl>

<dl>
    <dt><a name="-auth_tag"><strong>-tag</strong> <em>string</em></a></dt>
    <dt><a name="-tag"><strong>-tag</strong> <em>string</em></a></dt>
    <dd>Authenticated Encryption and Authenticated Data (AEAD) tag.
    Can be a binary or text string. Max is 16 bytes. A minimum of 12
    bytes is recommended.</dd>
</dl>

<dl>
    <dt><a name="-xof"><strong>-xof</strong> <em>boolean</em></a></dt>
    <dd>Set whether to use XOF. This option is used by KMAC.</dd>
</dl>

<br>
<h4>Input/Output Options</h4>

<dl>
    <dt><a name="-chan"><strong>-chan</strong> <em>channelId</em></a></dt>
    <dt><a name="-chan"><strong>-channel</strong> <em>channelId</em></a></dt>
    <dd>Add the cryptographic transformation on top of channel
	<em>channelId</em>. Automatically sets channel to binary mode. Works
	like <b>chan push</b> to create a stacked channel. If the command
	<b>fileevent</b> is to be used for channel event monitoring, all
	channels in the stack should be set to non-blocking mode. If not,
	the system may hang while waiting for data. When done, use either the
	close command or <a href="#tls::unstack"><strong>tls::unstack</strong></a>
	to remove the transform from the channel. Additional transforms cannot
	be added to channel. Example code:</dd></dl>
    <blockquote><code>
		set ch [open test_file.txt rb]<br>
		::tls::digest -digest sha256 -chan $ch<br>
		set data ""<br>
		while {![eof $ch]} {append data [read $ch 4096]}<br>
		close $ch<br>
		puts $data
    </code></blockquote>

<dl>
    <dt><a name="-command"><strong>-command</strong> <em>cmdName</em></a></dt>
    <dd>Create and return <em>cmdName</em> which is used to incrementally add
	data to a cryptographic function. To add data to the function, call
	&quot;<em>cmdName</em> <b>update</b> <em>data</em>&quot;, where
	<em>data</em> is the data to add. When done, call
	&quot;<em>cmdName</em> <b>finalize</b>&quot; to return the resulting
	value and delete <em>cmdName</em>. Example code:</dd></dl>
    <blockquote><code>
		set cmd [::tls::digest -digest sha256 -command ::tls::temp]<br>
		set data ""<br>
		append data [$cmd update "Some data. "]<br>
		append data [$cmd update "More data."]<br>
		append data [$cmd finalize]<br>
		puts $data
    </code></blockquote>

<dl>
    <dt><a name="-data"><strong>-data</strong> <em>string</em></a></dt>
    <dd>Perform the cryptographic function on <em>data</em> and return the
    result. Example code:</dd></dl>
    <blockquote><code>
		set md [::tls::digest sha256 "Some example data."]<br>
		puts $md
    </code></blockquote>

<dl>
    <dt><a name="-file"><strong>-file</strong> <em>filename</em></a></dt>
    <dt><a name="-file"><strong>-filename</strong> <em>filename</em></a></dt>
    <dd>Perform the cryptographic function on file <em>filename</em> and return
    the result. This operation will open file, read the file data, close the
    file, and return the result using the TCL file APIs, so VFS files are
    supported. Example code:</dd></dl>
    <blockquote><code>
		set md [::tls::digest -digest sha256 -file test_file.txt]<br>
		puts $md
    </code></blockquote>

<dl>
    <dt><a name="-infile"><strong>-infile</strong> <em>filename</em></a></dt>
    <dd>Specifies the file to use as data input source. This option uses the
    TCL file APIs, so VFS files are supported. Example code:</dd></dl>
    <blockquote><code>
		::tls::encrypt -cipher aes-128-cbc -key "Test key"
		-infile unencrypted.txt -outfile encrypted.dat
    </code></blockquote>

<dl>
    <dt><a name="-outfile"><strong>-outfile</strong> <em>filename</em></a></dt>
    <dd>Specifies the file to output the encryption results to. This option
    uses the TCL file APIs, so VFS files are supported. Example code:</dd></dl>
    <blockquote><code>
		::tls::decrypt -cipher aes-128-cbc -key "Test key"
		-infile encrypted.dat -outfile unencrypted.txt
    </code></blockquote>

<dl>
    <dt><a name="-keyfile"><strong>-keyfile</strong> <em>filename</em></a></dt>
    <dd>Specifies the file to get the encryption key from.</dd></dl>

<br>

<h4>Format Options</h4>

<dl>
    <dt><a name="-base64"><strong>-base64</strong></a></dt>
    <dd>Base64 encode data after encryption or decode before decryption.</dd>
</dl>

<dl>
    <dt><a name="-bin"><strong>-bin</strong></a></dt>
    <dt><a name="-bin"><strong>-binary</strong></a></dt>
    <dd>Output result of function as a binary string.</dd>
</dl>

<dl>
    <dt><a name="-hex"><strong>-hex</strong></a></dt>
    <dt><a name="-hex"><strong>-hexadecimal</strong></a></dt>
    <dd>Output result of function as a hexadecimal string. This is the default
	option unless otherwise specified.</dd>
</dl>

<br>

<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

	<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>

<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="https://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/TLS session.
</p>

<hr>

<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 command has no effect. This command supports all of the
	same options as the <strong>tls::socket</strong> 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>socket</strong> and <strong>tls::import</strong>) to create
	the connection. It behaves the same as the native TCL <strong>socket</strong>

	command, but also supports the <a href="#tls::import"><strong>tls:import</strong></a>
	command options and one additional option:</dd>
    <dl><blockquote>

	<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>

<h3><a name="CALLBACK OPTIONS">CALLBACK OPTIONS</a></h3>

<p>
As indicated above, individual channels can be given their own callbacks
to handle intermediate processing by the OpenSSL library, using the
<strong>-command</strong>, <strong>-password</strong>, and
<strong>-validate_command</strong> options passed to either of
<strong>tls::socket</strong> or <strong>tls::import</strong>.
If the callback generates an error, the <b>bgerror</b> command will be
invoked with the error information.

Reference implementations of these callbacks are provided in the
distribution as <strong>tls::callback</strong>, <strong>tls::password</strong>,
and <strong>tls::validate_command</strong> respectively.  Note that these are
<em>sample</em> implementations only.  In a more realistic deployment
you would specify your own callback scripts on each TLS channel using the
<strong>-command</strong>, <strong>-password</strong>, and <strong>-validate_command</strong> options.

</p>

<p>
The default behavior when the <strong>-command</strong> and <strong>-validate_command</strong>
options are not specified is for TLS to process the associated library callbacks
internally. The default behavior when the <strong>-password</strong> option is not
specified is for TLS to process the associated library callbacks by attempting
to call <strong>tls::password</strong>.
The difference between these two behaviors is a consequence of maintaining
compatibility with earlier implementations.
</p>

<p>
<em>
The use of the reference callbacks <strong>tls::callback</strong>,
<strong>tls::password</strong>, and <strong>tls::validate_command</strong>
is not recommended.  They may be removed from future releases.

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

TLS key logging can be enabled by setting the environment variable
<b>SSLKEYLOGFILE</b> to the name of the file to log to. Then whenever TLS
key material is generated or received it will be logged to the file. This
is useful for logging key data for network logging tools to use to
decrypt the data.

<p>
The <strong>tls::debug</strong> variable provides some additional
control over these reference callbacks.  Its value is zero by default.
Higher values produce more diagnostic output, and will also force the
verify method in <strong>tls::callback</strong> to accept the
certificate, even when it is invalid if the <b>tls::validate_command</b>
callback is used for the <b>-validatecommand</b> option.

<h4><a name="DEBUG_EXAMPLES">Debug Examples</a></h4>

<p>These examples use the default Unix platform SSL certificates. For standard
installations, -cadir and -cafile should not be needed. If your certificates
are in non-standard locations, update -cadir or use -cafile as needed.</p>

Example #1: Use HTTP package

installations, -cadir and -cafile should not be needed. If your certificates
are in non-standard locations, update -cadir or use -cafile as needed.</p>

<p>Example #1: Use HTTP package</p>
<pre><code>
package require http
package require tls
set url "https://www.tcl.tk/"

http::register https 443 [list ::tls::socket -autoservername true -require true -cadir /etc/ssl/certs \
    -command ::tls::callback -password ::tls::password -validatecommand ::tls::validate_command]
