Security
Internet Protocol Security (IPsec) is a suite of protocols for securing Internet Protocol (IP) communications by authenticating and/or encrypting each IP packet in a data stream. IPsec also includes protocols for cryptographic key establishment. IPsec was originally designed as a base specification in IPv6 (RFC 1825, RFC 1829) in 1995, but later updated. The protocol was adapted for use in IPv4 and found widespread adoption in securing virtual private networks.

—Ralph Waldo Emerson (1803–1882)
“I feel a sincere wish indeed to see our government brought back to it’s republican principles, to see that kind of government firmly fixed, to which my whole life has been devoted. I hope we shall now see it so established, as that when I retire, it may be under full security that we are to continue free and happy.”
—Thomas Jefferson (1743–1826)
