Transport-level encryption with Tcpcrypt
By Jake Edge
August 25, 2010

It has been said that the US National Security Agency (NSA) blocked the
implementation of encryption in the TCP/IP protocol for the original
ARPANET, because it wanted to be able to listen in on the traffic that
crossed that early precursor to the internet. Since that time, we have
been relegated to always sending clear-text packets via TCP/IP. Higher
level application protocols (i.e. ssh, HTTPS, etc.) have enabled
encryption for some traffic, but the vast majority of internet
communication is still in the clear. The Tcpcrypt project is an attempt
to change that, transparently, so that two conforming nodes can encrypt
all of the data portion of any packets they exchange.
