7 TCP Authentication Option (TCP-AO) provides a TCP extension aimed at verifying
8 segments between trusted peers. It adds a new TCP header option with
9 a Message Authentication Code (MAC). MACs are produced from the content
10 of a TCP segment using a hashing function with a password known to both peers.
11 The intent of TCP-AO is to deprecate TCP-MD5 providing better security,
12 key rotation and support for a variety of hashing algorithms.
