025     * 3. The KEY Resource Record
026     * 
027     *    The KEY resource record (RR) is used to store a public key that is
028     *    associated with a Domain Name System (DNS) name.  This can be the
029     *    public key of a zone, a user, or a host or other end entity. Security
030     *    aware DNS implementations MUST be designed to handle at least two
031     *    simultaneously valid keys of the same type associated with the same
032     *    name.
033     * 
034     *    The type number for the KEY RR is 25.
035     * 
036     *    A KEY RR is, like any other RR, authenticated by a SIG RR.  KEY RRs
037     *    must be signed by a zone level key.
038     * 
039     * 3.1 KEY RDATA format
040     * 
041     *    The RDATA for a KEY RR consists of flags, a protocol octet, the
042     *    algorithm number octet, and the public key itself.  The format is as
043     *    follows:
044     * 
045     *                         1 1 1 1 1 1 1 1 1 1 2 2 2 2 2 2 2 2 2 2 3 3
046     *     0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
047     *    +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
048     *    |             flags             |    protocol   |   algorithm   |
049     *    +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
050     *    |                                                               /
051     *    /                          public key                           /
052     *    /                                                               /
053     *    +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-|
054     * 
055     *    The KEY RR is not intended for storage of certificates and a separate
056     *    certificate RR has been developed for that purpose, defined in [RFC
057     *    2538].
