It utilizes either the OpenSSL or LibreSSL software library. Version 2.0 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 --enable-deterministic --with-builtin-dh-params-size=2048 $ 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-deterministic enable deterministic DH parameters --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 --with-builtin-dh-params-size=<bits> specify the size of the built-in, precomputed, DH params 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.
