      as encrypted strings. Since the encryption used is generally
      well known, it is possible to extract the original value from
      the string - and hence this format is not considered secure.
      Leaves specified with this type should not be modified by
      the system, and should be returned to the end-user in plain
      text. This type exists to differentiate passwords, which
      may be sensitive, from other string leaves. It could, for
      example, be used by the NMS to censor this data when
      viewed by particular users.";
