This is the GNU TLS library. More up to date information can be found at http://www.gnu.org/software/gnutls and http://www.gnutls.org It is a TLS implementation for the GNU project. It is currently under heavy development. (and still not ready for real world programs) * The library needs libgcrypt. Libgcrypt is part of gnupg (ftp.gnupg.org) * Documentation: view the doc/ directory and the examples in the src/ directory. LICENSE ISSUES: The latest release of the gnutls library is covered under the GNU Lesser GPL License, unlike previously released versions which were licensed under the GPL. The LGPL license (found in COPYING.LIB) applies to all parts of the gnutls library except for the "OPENPGP authentication" part, and the "SRP authentication" part, which stay GPL (see the COPYING file). Both of these parts can be disabled at compile time. In order to create a library under the LGPL run the configure script with the following parameters: --disable-srp-authentication --disable-openpgp-authentication or the library will be under the GPL. In both cases the libraries are binary compatible. In the LGPL case the functions are replaced with stubs that always fail. The rationale behind this license change is that given the fact that other free libraries with similar functionality exist, keeping the gnutls library GPL would not give any practical advantage to Free software developers. Please note that in many cases it is better for a library to be licensed under the GPL, so that it provides an advantage for free software projects. The Lesser GPL is so named because it does less to protect the freedom of the users of the code that it covers. See http://www.gnu.org/philosophy/why-not-lgpl.html for more explanation. BUGS: Currently gnuTLS needs a lot of testing. By notifying the developers about a possible bug you may help a lot, since testing is really important and expensive. If you think you found a bug, report it to bug-gnutls@gnu.org, together with the needed information, in order for developers to reproduce it.
