This is a port of OpenBSD's OpenIKED to different Unix-like operating systems, including Linux, macOS, FreeBSD and NetBSD.

The official documentation for OpenIKED are the man pages for each tool:

• iked(8)
• ikectl(8)
• iked.conf(5)

and the OpenBSD VPN FAQ.

Portable OpenIKED is built using cmake. It requires a working C compiler, standard library and headers, a yacc compatible parser generator, libevent, and libcrypto from either LibreSSL or OpenSSL.
