/etc/inet/secret/ike.preshared

The /etc/inet/secret/ike.preshared file contains secret keying material that two IKE instances can use to authenticate each other. Because of the sensitive nature of this data, it is kept in the /etc/inet/secret directory, which is only accessible by root.

Pre-shared keys are delimited by open-curly-brace ({) and close-curly-brace (}) characters. There are five name-value pairs required inside a pre-shared key:

Comment lines with # appearing in the first column are also legal.

Files in this format can also be used by the ikeadm(8) command to load additional pre-shared keys into a running an in.iked(8) process.

Example 1 A Sample ike.preshared File

The following is an example of an ike.preshared file:

#
# Two pre-shared keys between myself, 10.1.1.2, and two remote
# hosts. Note that names are not allowed for IP addresses.
#
# A decent hex string can be obtained by performing:
# od -x </dev/random | head
#

{
 localidtype IP
 localid 10.1.1.2
 remoteidtype IP
 remoteid 10.21.12.4
 key 4b656265207761732068657265210c0a
}

{
 localidtype IP
 localid 10.1.1.2
 remoteidtype IP
 remoteid 10.9.1.25
 key 536f20776572652042696c6c2c2052656e65652c20616e642043687269732e0a
}

If this file is compromised, all IPsec security associations derived from secrets in this file will be compromised as well. The default permissions on ike.preshared are 0600. They should stay this way.
