The KAME project, a sub-project of the WIDE Project, was a joint effort of six organizations in Japan that aimed to provide a free IPv6 and IPsec (for both IPv4 and IPv6) protocol stack implementation for variants of the BSD Unix computer operating-system.
[1] The project began in 1998, and on November 7, 2005, it was announced that it would be finished at the end of March 2006.
[2] The name KAME is a short version of Karigome, the location of the project's offices beside Keio University SFC.
The following organizations participated in the project: FreeBSD, NetBSD and DragonFly BSD integrated IPsec and IPv6 code from the KAME project; OpenBSD integrated just IPv6 code rather than both (having developed their own IPsec stack).
racoon, KAME's user-space daemon, handles Internet Key Exchange (IKE).
