The value of tmnxIPsecSAEncryptionKey specifies the key used
for the encryption algorithm defined by the
tmnxIPsecTransformEncrAlgorithm in the IPsec transform indexed
by tmnxIPsecSAManualTransformId.
The length of the key must match the length required by the
encryption algorithm. If a key of another length is set, the
request will fail with an 'inconsistentValue' error.
There is no default value for tmnxIPsecSAEncryptionKey and
this is a required object when creating an entry in
tmnxIPsecSATable. If tmnxIPsecSAEncryptionKey is not specified
when creating an entry, the request will fail with an
'inconsistentValue' error.
