"In computer networking, tcpcrypt is a transport layer communication encryption protocol. Unlike prior protocols like TLS (SSL), tcpcrypt is implemented as a TCP extension. It was designed by a team of six security and networking experts: Andrea Bittau, Mike Hamburg, Mark Handley, David Mazi\u00E8res, Dan Boneh and Quinn Slack. Tcpcrypt has been published as an Internet Draft. Experimental user-space implementations are available for Linux, Mac OS X, FreeBSD and Windows."@en . . . "Tcpcrypt"@en . . .
