024/**
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].
