o  id

    Support: All
    Default: No default    Value: Node ID

    Node ID of a potential neighbor node. You cannot modify this
    characteristic. This characteristic is set by means of an
    argument to the create command.

 o  verifier

    Support: All
    Default: No verifier   Value: Hex string, length 0-38

    Verifier to be checked from this neighbor. You may change this
    characteristic at any time; however, the change will not take
    effect until the circuit is next initialized. You cannot display
    this characteristic.

    If the verifier is not set, then a connection to the neighboring
    node whose ID matches the ID in this entry is allowed. If the
    verifier is set, the connection is allowed only if the verifier
    sent by the remote node matches the one in this entry.
