<para>The <varname>Key=</varname> parameter specifies the same key to use in

both directions (<varname>InputKey=</varname> and <varname>OutputKey=</varname>).
|

The <varname>Key=</varname> is either a number or an IPv4 address-like dotted quad.
|

It is used as mark-configured SAD/SPD entry as part of the lookup key (both in data
|
||||
and control path) in ip xfrm (framework used to implement IPsec protocol).

See <ulink url="http://man7.org/linux/man-pages/man8/ip-xfrm.8.html">
