This is a development mirror of OpenBSD's iked.

iked is a lean Internet Key Exchange (IKEv2) daemon which performs mutual authentication and which establishes and maintains IPsec VPN flows and security associations (SAs) between the two peers. The IKEv2 protocol is defined in RFC 5996, which combines and updates the previous standards: ISAKMP/Oakley (RFC 2408), IKE (RFC 2409), and the Internet DOI (RFC 2407). iked only supports the IKEv2 protocol; support for ISAKMP/Oakley and IKEv1 is provided by OpenBSD's isakmpd(8) or other implementations on non-OpenBSD platforms.

iked supports mutual authentication using RSA public keys and X.509 certificates, it also support responder/server-side authentication of clients using the EAP-MSCHAPv2 protocol over IKEv2. It interconnects with other IKEv2 implementations like the native IKEv2 implementation of Windows 7 or newer (aka Agile VPN) or strongSwan.

The main development of iked is being done for OpenBSD and the source tree is found in OpenBSD's CVS repository. Like most of the projects from the OpenBSD repository, the original source code does not include any portability glue (#ifdefs) and is specifically developed for OpenBSD.

The main development tree is found in the src/sbin/iked and src/usr.sbin/ikectl directories of the OpenBSD CVS repository:
