GNU Transport Layer Security Library, is afree software implementation of the SSL and TLS protocols. Its purpose is to offer anapplication programming interface (API) for applications to enable secure communication protocols over their network transport layer.Features
GnuTLS has the following features:
* SSL 3.0, TLS 1.0, TLS 1.1 protocols and the currently in draft TLS 1.2 protocol
*Secure remote password protocol (SRP) for TLS authentication
*Pre-shared key (PSK) for TLS authentication
* TLS Extension mechanism
* TLS Compression
*X.509 and OpenPGP certificate handlingLicence and motivation
GnuTLS is licensed under the
GNU Lesser General Public License ; some parts are licensed under theGNU General Public License .GnuTLS was initially created to allow applications of the
GNU project to use secure protocols such as TLS. AlthoughOpenSSL already existed, OpenSSL's license is not compatible with the GPL [cite web

GNOME ,CenterIM ,Exim , Mutt,Slrn , Lynx, and CUPS. [ [http://www.gnu.org/software/gnutls/programs.html The GNU Transport Layer Security Library] ]See also
