It also includes language bindings for Perl (Apache::Request and Apache::Cookie). gloox gloox is a C++ Jabber/XMPP library which takes care of the low-level protocol stuff. Additionally, it offers high-level interfaces for interaction with an XMPP server. It is released under the GNU GPL. Commercial licenses are available. GNU Transport Layer Security Library aims to develop a library which provides a secure layer, over a reliable transport layer. Currently the GnuTLS library implements the proposed standards by the IETF's TLS working group GOBLIN a C++ class library focussed on graph optimization and network programming problems. It deals with all of the standard graph optimization problems discussed by textbooks and in courses on combinatorial optimization GSSLib GNU Generic Security Service Library: is an implementation of the Generic Security Service API (GSSAPI). It is used by network applications to provide security services, such as authenticating SMTP/IMAP, via the GSSAPI SASL mechanism GTK-VNC GTK-VNC is a VNC viewer widget for GTK+. It is built using coroutines, allowing it to be completely asynchronous while remaining single threaded. It supports RFB protocols 3.3 through 3.8 and the VeNCrypt authentication extension providing SSL/TLS encryption with x509 certificate authentication. The core library is written in C and a binding for Python using PyGTK is available. The networking layer supports connections over both IPv4 and IPv6.
