It provides a generic -binding to OpenSSL, utilizing the -Tcl_StackChannel API in Tcl 8.4 and higher. +binding to OpenSSL, utilizing the +Tcl_StackChannel API in TCL 8.4 and higher.

+
Specifies the private key to use as a DER encoded string (PKCS#1 DER).
-model channel
Force this channel to share the same SSL_CTX structure as the specified channel, and therefore share callbacks etc.
-password callback
-
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 CALLBACK OPTIONS - for further discussion.

CERTIFICATE VALIDATION

+ +

+By default, a client TLS connection is set to NOT request nor validate the +server certificates. 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 -require option, one of the following must be true:

+
    +
  • On Linux and Unix systems with OpenSSL already installed, if the CA +certificates are stored in the standard locations, or the SSL_CERT_DIR +or SSL_CERT_FILE env vars are set, then no other options are needed.
  • + +
  • If OpenSSL is not installed in the default location, or when using Mac OS +or Windows and OpenSSL is installed, the SSL_CERT_DIR and/or +SSL_CERT_FILE env vars or the -cadir and/or -cafile + options must be defined.
  • + +
  • 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 -castore option to "org.openssl.winstore://".
  • + +
  • If OpenSSL is not installed, the CA certificates must be downloaded and +installed with the user software. The CURL team makes them available at +CA certificates extracted +from Mozilla. Look for the cacert.pem file. You must then either +set the SSL_CERT_DIR and/or SSL_CERT_FILE env vars or the +-cadir or -cafile options must be set to the file's install +location. It is your responsibility to keep this file up to date.
  • +
+
+ +

CALLBACK OPTIONS

As indicated above, individual channels can be given their own callbacks to handle intermediate processing by the OpenSSL library, using the -command, -password, and -validate_command options passed to either of tls::socket or tls::import. -If the callback generates an error, the bgerror command will be -invoked with the error information. +Unlike previous versions of TCL TLS, only if the callback generates an error, +will the bgerror command will be invoked with the error information.

The default behavior when the -password option is not specified is for TLS to process the associated library callbacks by attempting to call tls::password. The difference between these two behaviors is a consequence of maintaining compatibility with earlier implementations.

 # Running socket tests with a remote server:
 # ------------------------------------------
-# 
+#
 # Some tests in socket.test depend on the existence of a remote server to
 # which they connect. The remote server must be an instance of tcltest and it
 # must run the script found in the file "remote.tcl" in this directory. You
 # can start the remote server on any machine reachable from the machine on
 # which you want to run the socket tests, by issuing:
-# 
+#
 #     tcltest remote.tcl -port 8048	# Or choose another port number.
-# 
+#
 # If the machine you are running the remote server on has several IP
 # interfaces, you can choose which interface the server listens on for
 # connections by specifying the -address command line flag, so:
-# 
+#
 #     tcltest remote.tcl -address your.machine.com
-# 
+#
 # These options can also be set by environment variables. On Unix, you can
 # type these commands to the shell from which the remote server is started:
-# 
+#
 #     shell% setenv serverPort 8048
 #     shell% setenv serverAddress your.machine.com
-# 
+#
 # and subsequently you can start the remote server with:
-# 
+#
 #     tcltest remote.tcl
-# 
+#
 # to have it listen on port 8048 on the interface your.machine.com.
-#     
+#
 # When the server starts, it prints out a detailed message containing its
 # configuration information, and it will block until killed with a Ctrl-C.
 # Once the remote server exists, you can run the tests in socket.test with
 # the server by setting two Tcl variables:
-# 
+#
 #     % set remoteServerIP 
 #     % set remoteServerPort 8048
-# 
+#
 # These variables are also settable from the environment. On Unix, you can:
-# 
+#
 #     shell% setenv remoteServerIP machine.where.server.runs
 #     shell% setenv remoteServerPort 8048
-# 
+#
 # The preamble of the socket.test file checks to see if the variables are set
 # either in Tcl or in the environment; if they are, it attempts to connect to
 # the server. If the connection is successful, the tests using the remote
 # server will be performed; otherwise, it will attempt to start the remote
 # server (via exec) on platforms that support this, on the local host,
