Tool Command Language (TCL) Transport Layer Security (TLS) Extension

Intro
=====

This package provides an extension which implements Secure Socket Layer (SSL)
and Transport Layer Security (TLS) over Transmission Control Protocol (TCP)
network communication channels. It utilizes either the OpenSSL or LibreSSL
software library.

Version 1.9 also provides a cryptography library providing TCL scripts access
to the crypto capabilities of the OpenSSL library.


Description
===========

This extension works by creating a layered TCL Channel on top of an existing
bi-directional channel created by the TLS socket command. All existing socket
functionality is supported, in addition to several new options. Both client
and server modes are supported.


Documentation
=============

See the doc directory for the full usage documentation.


Compatibility
=============




This package requires TCL 8.5 or later.







This package is compatible with:
- OpenSSL v1.1.1 or later. See (http://www.openssl.org/



- LibreSSL (TBD version)








Installation
============

This package uses the Tcl Extension Architecture (TEA) to build and install on
any supported Unix, Mac, or MS Windows system. Either the OpenSSL or LibreSSL
software libraries must be built and available prior to building TCL TLS.

UNIX and Linux
--------------

The standard TEA config, make and install process is supported.

	$ cd tcltls
	$ ./configure --enable-64bit
	$ make
	$ make test
	$ make install

The supported configure options include all of the standard TEA configure script
options, plus:

  --disable-tls1          disable TLS1 protocol
  --disable-tls1_1        disable TLS1.1 protocol
  --disable-tls1_2        disable TLS1.2 protocol
  --disable-tls1_3        disable TLS1.3 protocol

  --enable-ssl-fastpath   enable using the underlying file descriptor for talking directly to the SSL library
  --enable-hardening      enable hardening attempts
  --enable-static-ssl     enable static linking to the SSL library

If either TCL or OpenSSL are installed in non-standard locations, the following
configure options are available. For all options, see ./configure --help.

  --with-tcl=<dir>			path to where tclCondig.sh file resides
  --with-tclinclude=<dir>		directory containing the public Tcl header files
  --with-openssl-dir=<dir>		path to root directory of OpenSSL or LibreSSL installation
  --with-openssl-includedir=<dir>	path to include directory of OpenSSL or LibreSSL installation
  --with-openssl-libdir=<dir>		path to lib directory of OpenSSL or LibreSSL installation
  --with-openssl-pkgconfig=<dir>	path to root directory of OpenSSL or LibreSSL pkgconfigdir


MacOS
-----

The standard TEA installation process is supported. Use the --with-tcl option
to set the TCL path if the ActiveState or other non-Apple version of TCL is to
be used.

	$ cd tcltls
	$ ./configure --with-tcl=/Library/Frameworks/Tcl.framework/
	$ make
	$ make test
	$ make install


Windows
-------

If installing with MinGW, use the TEA build process. If using MS Visual C

(MSVC), see the win/README.txt file for the installation instructions.

Tool Command Language (TCL) Transport Layer Security (TLS) Extension

Intro

and Transport Layer Security (TLS) encryption over Transmission Control
Protocol (TCP) network communication channels utilizing the OpenSSL library.






Description
===========

This extension works by creating a layered TCL Channel on top of an existing
bi-directional channel created by the TLS socket command. All existing socket
functionality is supported in addition to several new options. Both client and
server modes are supported.


Documentation
=============

See the doc directory for the full usage documentation.


Compatibility
=============

TCL
---

This package requires TCL 8.5 or later. It will also work with TCL 9, but it is
not binary compatible between major TCL versions. This means if this extension
is built with TCL 8.x it will not load into TCL 9 or vice versa. It is best
to compile both separately then install them with the compatible TCL versions.

OpenSSL
-------

This package is compatible with OpenSSL v1.1.1 or later, though 3.2 or later is
preferred. See http://www.openssl.org/. Please note that there are a few API
incompatibilities between OpenSSL 1.1.1 and 3.x, so if this extension is built
against OpenSSL 1.1.1 it is not binary compatible with OpenSSL 3.x or vice
versa.

TCLTLS
------

There were several changes made in the callback command arguments between
versions 1.7 and 2.0. See the doc/tls.html for what changed and library/tls.tcl
for example handler functions that are backwards compatible.


Installation
============

This package uses the TCL Extension Architecture (TEA) to build and install on
any supported Unix, Mac, or MS Windows system. It depends on the OpenSSL
libraries being available prior to building the TCLTLS extension.

UNIX and Linux
--------------

The standard TEA config, make, and install process is supported.

	$ cd tcltls
	$ ./configure --enable-64bit
	$ make
	$ make test
	$ make install

The supported configure options include all of the standard TEA configure
script options, plus:

  --disable-tls1          disable TLS1 protocol
  --disable-tls1_1        disable TLS1.1 protocol
  --disable-tls1_2        disable TLS1.2 protocol
  --disable-tls1_3        disable TLS1.3 protocol
  --enable-debug          enable debugging mode and output more status
  --enable-ssl-fastpath   enable using the underlying file descriptor for talking directly to the SSL library
  --enable-hardening      enable hardening attempts
  --enable-static-ssl     enable static linking to the SSL library

If either TCL or OpenSSL are installed in non-standard locations, the following
configure options are available. For all options, see ./configure --help.

  --with-tcl=<dir>			path to where tclCondig.sh file resides
  --with-tclinclude=<dir>		directory containing the public Tcl header files
  --with-openssl-dir=<dir>		path to root directory of OpenSSL installation
  --with-openssl-includedir=<dir>	path to include directory of OpenSSL installation
  --with-openssl-libdir=<dir>		path to lib directory of OpenSSL installation
  --with-openssl-pkgconfig=<dir>	path to root directory of OpenSSL pkg-config directory


MacOS
-----

The standard TEA installation process is supported. Use the --with-tcl option
to set the TCL path if the ActiveState or other non-Apple version of TCL is to
be used.

	$ cd tcltls
	$ ./configure --with-tcl=/Library/Frameworks/Tcl.framework/
	$ make
	$ make test
	$ make install


Windows
-------

If installing with MinGW, use the TEA build process. If using MS Visual C
(MSVC), see win/README.txt for the build and installation instructions.


Certificate Validation
----------------------

If OpenSSL is not installed on the system, the Certificate Authority (CA)
provided certificates must be downloaded and installed with the software.
These are used for certificate validation. The CURL team makes them available
at https://curl.se/docs/caextract.html. Look for the cacert.pem file.

'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]
  --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
  --sharedstatedir=DIR    modifiable architecture-independent data [PREFIX/com]
  --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
  --runstatedir=DIR       modifiable per-process data [LOCALSTATEDIR/run]
  --libdir=DIR            object code libraries [EPREFIX/lib]
  --includedir=DIR        C header files [PREFIX/include]
  --oldincludedir=DIR     C header files for non-gcc [/usr/include]
  --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]
  --datadir=DIR           read-only architecture-independent data [DATAROOTDIR]
  --infodir=DIR           info documentation [DATAROOTDIR/info]

<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.

	    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

	    delete ("-"), or move a cipher 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.</dd>

	    therefore share callbacks etc.</dd>
	<dt><strong>-password</strong> <em>callback</em></dt>
	<dd>Specifies the callback command to invoke when OpenSSL needs to
	    obtain a password. This is typically used to unlock the private key of
	    a certificate. The callback should return a password string.
	    See <a href="#CALLBACK OPTIONS">CALLBACK OPTIONS</a> for more info.</dd>

	<dt><strong>-post_handshake</strong> <em>bool</em></dt>
	<dd>Allow post-handshake session ticket updates.</dd>

	    See <a href="#CERTIFICATE VALIDATION">CERTIFICATE VALIDATION</a>.</dd>
	<dt><strong>-security_level</strong> <em>integer</em></dt>
	<dd>Specifies the security level (value from 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 prior to OpenSSL 3.2
	    and 2 thereafter. Level 3 and higher disable support for session
	    tickets and only accept cipher suites that provide forward secrecy.</dd>

	<dt><strong>-validatecommand</strong> <em>callback</em></dt>
	<dd>Specifies the callback command to invoke to validate protocol
	    config parameters during the protocol negotiation phase. This can be
	    used by TCL scripts to perform their own certificate validation to
	    supplement the default validation provided by OpenSSL. The script must
	    return a boolean true to continue the negotiation. See

<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.
</p>

<blockquote>
<dl>

    <dt><strong>-command</strong> <em>callback</em></dt>
    <dd>
	Invokes the specified <em>callback</em> script at several points
	during the OpenSSL handshake and use. See below for the possible
	arguments passed to the callback script. Values returned from the
	callback are ignored.

	<br>
	<br>

	<dl>

	<dt>
	  <strong>error</strong> <em>channelId message</em>
	</dt>
	<dd>
	  This form of callback is invoked whenever an error occurs during the
	  initial connection, handshake, or I/O operations. The <em>message</em>
	  argument can be from the Tcl_ErrnoMsg, OpenSSL function
	  <code>ERR_reason_error_string()</code>, or a custom message.
	</dd>

	<br>

	<dt>
	  <strong>info</strong> <em>channelId major minor message type</em>
	</dt>
	<dd>
	  This form of callback is invoked by the OpenSSL function
	  <code>SSL_set_info_callback()</code> during the initial connection
	  and handshake operations. The <em>type</em> argument is new for
	  TLS 1.8. The arguments are:
	  <br>
	  <ul>
	  <li>Possible values for <em>major</em> are:
	  <code>handshake, alert, connect, accept</code>.</li>
	  <li>Possible values for <em>minor</em> are:
	  <code>start, done, read, write, loop, exit</code>.</li>
	  <li>The <em>message</em> argument is a descriptive string which may
	  be generated either by <code>SSL_state_string_long()</code> or by
	  <code>SSL_alert_desc_string_long()</code>, depending on the context.</li>
	  <li>For alerts, the possible values for <em>type</em> are:
	  <code>warning, fatal, and unknown</code>. For others,
	  <code>info</code> is used.</li>
	  </ul>
	</dd>

	<dt>
	  <strong>message</strong> <em>channelId direction version content_type message</em>
	</dt>
	<dd>
	  This form of callback is invoked by the OpenSSL function
	  <code>SSL_set_msg_callback()</code> whenever a message is sent or
	  received during the initial connection, handshake, or I/O operations.
	  It is only available when OpenSSL is complied with the
	  <em>enable-ssl-trace</em> option. Arguments are: <em>direction</em>
	  is <b>Sent</b> or <b>Received</b>, <em>version</em> is the protocol
	  version, <em>content_type</em> is the message content type, and
	  <em>message</em> is more info from the <code>SSL_trace</code> API.
	  This callback is new for TLS 1.8.
	</dd>
	<br>

	<dt>
	  <strong>session</strong> <em>channelId session_id ticket lifetime</em>
	</dt>
	<dd>
	  This form of callback is invoked by the OpenSSL function
	  <code>SSL_CTX_sess_set_new_cb()</code> whenever a new session id is
	  sent by the server during the initial connection and handshake, but
	  can also be received later if the <b>-post_handshake</b> option is
	  used. Arguments are: <em>session_id</em> is the current
	  session identifier, <em>ticket</em> is the session ticket info, and
	  <em>lifetime</em> is the the ticket lifetime in seconds.
	  This callback is new for TLS 1.8.
	</dd>
	<br>
	</dl>
    </dd>

    <br>

    <dt><strong>-password</strong> <em>callback</em></dt>
    <dd>
	Invokes the specified <em>callback</em> script when OpenSSL needs to
	obtain a password. See below for the possible arguments passed to
	the callback script. See below for valid return values.

	<br>
	<br>

	<dl>

	<dt>
	  <strong>password</strong> <em>rwflag size</em>
	</dt>
	<dd>
	  Invoked when loading or storing a PEM certificate with encryption.
	  Where <em>rwflag</em> is 0 for reading/decryption or 1 for
	  writing/encryption (can prompt user to confirm) and
	  <em>size</em> is the max password length in bytes.
	  The callback should return the password as a string.
	  Both arguments are new for TLS 1.8.
	</dd>

    </dd>

    <br>


    <dt><strong>-validatecommand</strong> <em>callback</em></dt>
    <dd>
	Invokes the specified <em>callback</em> script during handshake in
	order to validate the provided value(s). See below for the possible
	arguments passed to the callback script. If not specified, OpenSSL
	will accept valid certificates and extensions.
	To reject the value and abort the connection, the callback should return 0.
	To accept the value and continue the connection, it should return 1.
	To reject the value, but continue the connection, it should return 2.

	<br>
	<br>

	<dl>

	<dt>
	  <strong>alpn</strong> <em>channelId protocol match</em>
	</dt>
	<dd>
	  For servers, this form of callback is invoked when the client ALPN
	  extension is received. If <em>match</em> is true, <em>protocol</em>
	  is the first <b>-alpn</b> option specified protocol common to both
	  the client and server. If not, the first client specified protocol is
	  used. It is called after the hello and ALPN callbacks.
	  This callback is new for TLS 1.8.
	</dd>

	<br>

	<dt>
	  <strong>hello</strong> <em>channelId servername</em>
	</dt>
	<dd>
	  For servers, this form of callback is invoked during client hello
	  message processing. The purpose is so the server can select the
	  appropriate certificate to present to the client, and to make other
	  configuration adjustments relevant to that server name and its
	  configuration. It is called before the SNI and ALPN callbacks.
	  This callback is new for TLS 1.8.
	</dd>

	<br>

	<dt>
	  <strong>sni</strong> <em>channelId servername</em>
	</dt>
	<dd>
	  For servers, this form of callback is invoked when the Server Name
	  Indication (SNI) extension is received. The <em>servername</em>
	  argument is the client provided server name in the <b>-servername</b>
	  option. The purpose is so when a server supports multiple names, the
	  right certificate can be used. It is called after the hello callback
	  but before the ALPN callback.
	  This callback is new for TLS 1.8.
	</dd>

	<br>

	<dt>
	  <strong>verify</strong> <em>channelId depth cert status error</em>
	</dt>
	<dd>
	  This form of callback is invoked by OpenSSL when a new certificate
	  is received from the peer. It allows the client to check the
	  certificate verification results and choose whether to continue
	  or not. It is called for each certificate in the certificate chain.
	  <ul>
	  <li>The <em>depth</em> argument is the integer depth of the
	  certificate in the certificate chain, where 0 is the peer certificate
	  and higher values going up to the Certificate Authority (CA).</li>
	  <li>The <em>cert</em> argument is a list of key-value pairs similar
	  to those returned by
	  <a href="#tls::status"><strong>tls::status</strong></a>.</li>
	  <li>The <em>status</em> argument is the boolean validity of the
	  current certificate where 0 is invalid and 1 is valid.</li>
	  <li>The <em>error</em> argument is the error message, if any, generated
	  by <code>X509_STORE_CTX_get_error()</code>.</li>
	  </ul>
	</dd>
	<br>
	</dl>
    </dd>
</dl>

<p>
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.
</em>
</p>




<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.
</p>

<p>
<em>
The use of the variable <strong>tls::debug</strong> is not recommended.
It may be removed from future releases.
</em>
</p>

<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>
<br>
Example #1: Use HTTP package


<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]

<h3><a name="CERTIFICATE VALIDATION">CERTIFICATE VALIDATION</a></h3>

<h4>Summary of command line options:</h4>
<p>The following options are used for certificate validation:</p>
<ul>
<li>The <b>-cadir</b> option specifies the directory where the Certificate
Authority (CA) certificates are stored. The default is platform specific, but
is usually "/etc/ssl/certs" on Linux/Unix systems. The default location can be
overridden via the <b>SSL_CERT_DIR</b> environment variable.</li>
<li>The <b>-cafile </b> option specifies the file that contains all of the
Certificate Authority (CA) certificates in the PEM file format. The default is
<b>cert.pem</b>, in the OpenSSL directory. On Linux/Unix systems, this is
usually "/etc/ssl/ca-bundle.pem". The default file can be overridden via the
<b>SSL_CERT_FILE</b> environment variable.</li>
<li>The <b>-castore</b> option contains the URI to the Certificate Authority
(CA) store, which may be a single container or a catalog of containers.
Starting with OpenSSL 3.2 on Windows, set this to "org.openssl.winstore://" to
use the built-in Windows Certificate Store. The Windows cert store only
supports root certificate stores.</li>
<li>The <b>-request</b> option is used to request the server send its
certificate chain as part of the connection negotiation process. This is
needed to do certificate validation. The default is true. In addition, the
client can manually inspect and accept or reject each certificate using the
<b>-validatecommand</b> option.</li>
<li>The <b>-require</b> option is used to require certificate validation be
performed as part of the connection negotiation process. A valid CA directory,
file, or store must be present for this to work.</li>
</ul>

<br>
<h4>When are command line options needed:</h4>
<p>
By default, a client TLS connection does NOT validate the server certificate
chain. This limitation is due to the lack of a common cross platform
database of Certificate Authority (CA) provided certificates to validate
against. Many Linux systems natively support OpenSSL and thus have these
certificates installed as part of the OS, but MacOS and Windows do not. In
order to use the <b>-require</b> option, one of the following must be true:</p>
<ul>
<li>On Linux and Unix systems with OpenSSL already installed, if the CA
certificates are stored in the standard locations, or the <b>SSL_CERT_DIR</b>
or <b>SSL_CERT_FILE</b> env vars are set, then no other options are needed.</li>

<li>If OpenSSL is not installed in the default location, or when using Mac OS
or Windows and OpenSSL is installed, the <b>SSL_CERT_DIR</b> and/or 
<b>SSL_CERT_FILE</b> env vars or the <b>-cadir</b> and/or <b>-cafile</b>
 options must be defined.</li>

<li>On Windows, starting in OpenSSL 3.2, it is now possible to access the
built-in Windows Certificate Store from OpenSSL. This can be achieved by
setting the <b>-castore</b> option to "<b>org.openssl.winstore://</b>".</li>

<li>If OpenSSL is not installed, the CA certificates must be downloaded and
installed with the user software. The CURL team makes them available at
<a href="https://curl.se/docs/caextract.html">CA certificates extracted
from Mozilla</a> in the <b>cacert.pem</b> file. You must then either
set the <b>SSL_CERT_DIR</b> and/or <b>SSL_CERT_FILE</b> env vars or the
<b>-cadir</b> or <b>-cafile</b> options must be set to the file's install
location. It is your responsibility to keep this file up to date.</li>
</ul>

<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>.
Unlike previous versions of TCL TLS, only if the callback generates an error,
will the <b>bgerror</b> command will be invoked with the error information.
</p>


<dl>

    <dt><strong>-command</strong> <em>callback</em></dt>
    <dd>
	Invokes the specified <em>callback</em> script at several points
	during the OpenSSL handshake and use. See below for the possible
	arguments passed to the callback script. Values returned from the
	callback are ignored.

    <br>


    <dl>

	<dt>
	<strong>error</strong> <em>channelId message</em>
	</dt>
	<dd>
	    This form of callback is invoked whenever an error occurs during the
	    initial connection, handshake, or I/O operations. The <em>message</em>
	    argument can be from the Tcl_ErrnoMsg, OpenSSL function
	    <code>ERR_reason_error_string()</code>, or a custom message.
	</dd>

	<br>

	<dt>
	    <strong>info</strong> <em>channelId major minor message type</em>
	</dt>
	<dd>
	     This form of callback is invoked by the OpenSSL function
	    <code>SSL_set_info_callback()</code> during the initial connection
	    and handshake operations. The <em>type</em> argument is new for
	    TLS 1.8. The arguments are:
	<br>
	<ul>
	<li>Possible values for <em>major</em> are:
	    <code>handshake, alert, connect, accept</code>.</li>
	<li>Possible values for <em>minor</em> are:
	    <code>start, done, read, write, loop, exit</code>.</li>
	<li>The <em>message</em> argument is a descriptive string which may
	    be generated either by <code>SSL_state_string_long()</code> or by
	    <code>SSL_alert_desc_string_long()</code>, depending on the context.</li>
	<li>For alerts, the possible values for <em>type</em> are:
	    <code>warning, fatal, and unknown</code>. For others,
	    <code>info</code> is used.</li>
	</ul>
	</dd>

	<dt>
	<strong>message</strong> <em>channelId direction version content_type message</em>
	</dt>
	<dd>
	    This form of callback is invoked by the OpenSSL function
	    <code>SSL_set_msg_callback()</code> whenever a message is sent or
	    received during the initial connection, handshake, or I/O operations.
	    It is only available when OpenSSL is complied with the
	    <em>enable-ssl-trace</em> option. Arguments are: <em>direction</em>
	    is <b>Sent</b> or <b>Received</b>, <em>version</em> is the protocol
	    version, <em>content_type</em> is the message content type, and
	    <em>message</em> is more info from the <code>SSL_trace</code> API.
	    This callback is new for TLS 1.8.
	</dd>
	<br>

	<dt>
	<strong>session</strong> <em>channelId session_id ticket lifetime</em>
	</dt>
	<dd>
	    This form of callback is invoked by the OpenSSL function
	    <code>SSL_CTX_sess_set_new_cb()</code> whenever a new session id is
	    sent by the server during the initial connection and handshake, but
	    can also be received later if the <b>-post_handshake</b> option is
	    used. Arguments are: <em>session_id</em> is the current
	    session identifier, <em>ticket</em> is the session ticket info, and
	    <em>lifetime</em> is the the ticket lifetime in seconds.
	    This callback is new for TLS 1.8.
	</dd>

    </dl>
    </dd>
</dl>
<br>
<dl>
    <dt><strong>-password</strong> <em>callback</em></dt>
    <dd>
	Invokes the specified <em>callback</em> script when OpenSSL needs to
	obtain a password. See below for the possible arguments passed to
	the callback script. See below for valid return values.

	<br>


	<dl>

	    <dt>
	    <strong>password</strong> <em>rwflag size</em>
	    </dt>
	    <dd>
		Invoked when loading or storing a PEM certificate with encryption.
		Where <em>rwflag</em> is 0 for reading/decryption or 1 for
		writing/encryption (can prompt user to confirm) and <em>size</em> is
		the max password length in bytes. The callback should return the

		password as a string. Both arguments are new for TLS 1.8.
	    </dd>
	</dl>
    </dd>
</dl>
<br>
<dl>

    <dt><strong>-validatecommand</strong> <em>callback</em></dt>
    <dd>
	Invokes the specified <em>callback</em> script during handshake in
	order to validate the provided value(s). See below for the possible
	arguments passed to the callback script. If not specified, OpenSSL
	will accept valid certificates and extensions.
	To reject the value and abort the connection, the callback should return 0.
	To accept the value and continue the connection, it should return 1.
	To reject the value, but continue the connection, it should return 2.

	<br>


	<dl>

	    <dt>
		<strong>alpn</strong> <em>channelId protocol match</em>
		</dt>
	    <dd>
		For servers, this form of callback is invoked when the client ALPN
		extension is received. If <em>match</em> is true, <em>protocol</em>
		is the first <b>-alpn</b> option specified protocol common to both
		the client and server. If not, the first client specified protocol is
		used. It is called after the hello and ALPN callbacks.
		This callback is new for TLS 1.8.
	    </dd>

	    <br>

	    <dt>
		<strong>hello</strong> <em>channelId servername</em>
	    </dt>
	    <dd>
		For servers, this form of callback is invoked during client hello
		message processing. The purpose is so the server can select the
		appropriate certificate to present to the client, and to make other
		configuration adjustments relevant to that server name and its
		configuration. It is called before the SNI and ALPN callbacks.
		This callback is new for TLS 1.8.
	    </dd>

	    <br>

	    <dt>
		<strong>sni</strong> <em>channelId servername</em>
	    </dt>
	    <dd>
		For servers, this form of callback is invoked when the Server Name
		Indication (SNI) extension is received. The <em>servername</em>
		argument is the client provided server name in the <b>-servername</b>
		option. The purpose is so when a server supports multiple names, the
		right certificate can be used. It is called after the hello callback
		but before the ALPN callback.
		This callback is new for TLS 1.8.
	    </dd>

	    <br>

	    <dt>
		<strong>verify</strong> <em>channelId depth cert status error</em>
	    </dt>
	    <dd>
		This form of callback is invoked by OpenSSL when a new certificate
		is received from the peer. It allows the client to check the
		certificate verification results and choose whether to continue
		or not. It is called for each certificate in the certificate chain.
		<ul>
		<li>The <em>depth</em> argument is the integer depth of the
		certificate in the certificate chain, where 0 is the peer certificate
		and higher values going up to the Certificate Authority (CA).</li>
		<li>The <em>cert</em> argument is a list of key-value pairs similar
		to those returned by
		<a href="#tls::status"><strong>tls::status</strong></a>.</li>
		<li>The <em>status</em> argument is the boolean validity of the
		current certificate where 0 is invalid and 1 is valid.</li>
		<li>The <em>error</em> argument is the error message, if any, generated
		by <code>X509_STORE_CTX_get_error()</code>.</li>
		</ul>
	    </dd>
	    <br>
	</dl>
    </dd>
</dl>


<p>
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.
</em>
</p>
<br>

<hr>

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

<p>For most debugging needs, the <b>-callback</b> option can be used to provide
sufficient insight and information on the TLS handshake and progress. If further
troubleshooting insight is needed, the compile time option <b>--enable-debug</b>
can be used to get detailed execution flow status.</p>

<p>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>


<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.</p>




<p><em>The use of the variable <strong>tls::debug</strong> is not recommended.
It may be removed from future releases.</em></p>



<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>
