The IKE session encrypt key.
The IKE session authentication
key.
The key used to generate IKE
skeyid during preshared-key
authentication. "no crypto isakmp
key" command zeroizes it. This key
can have two forms based on
whether the key is related to the
hostname or the IP address.
This key generates the IKE shared
secret keys. This key is zeroized
after generating those keys.
RSA private key for IKE
authentication. Generated or
entered like any RSA key, set as
IKE RSA Authentication Key with
the "crypto keyring" or "ca trust-
point" command.
RSA public key for IKE
authentication. Generated or
entered like any RSA key, set as
IKE RSA Authentication Key with
the "crypto keyring" or "ca trust-
point" command.
RSA private key for IKE encrypted
nonces. Generated like any RSA,
with the "usage-keys" parameter
included.
RSA public key for IKE encrypted
nonces. Generated like any RSA,
with the "usage-keys" parameter
included.
The IPSec encryption key. Zeroized
when IPSec session is terminated.
The IPSec authentication key. The
zeroization is the same as above.
The key used to encrypt values of
the configuration file. This key is
zeroized when the "no key config-
key" is issued. Note that this
command does not decrypt the
configuration file, so zeroize with
care.
This key is used by the router to
authenticate itself to the peer. The
router itself gets the password (that
is used as this key) from the AAA
server and sends it onto the peer.
The password retrieved from the
