     "GnuTLS is a project that 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.

\"The TLS protocol provides communications privacy over the
Internet. The protocol allows client/server applications to communicate
in a way that is designed to prevent eavesdropping, tampering, or
message forgery.\"")
