    Key class

    This class can contains all types of keys that are used in DNSSEC. Mostly used to store private keys, since public keys can also be stored in a ldns_rr with type LDNS_RR_TYPE_DNSKEY. This class can also store some variables that influence the signatures generated by signing with this key, for instance the inception date.

    **Usage**

     >>> import ldns
     >>> ldns.ldns_init_random(open("/dev/random","rb"), 512/8)
     >>> key = ldns.ldns_key.new_frm_algorithm(ldns.LDNS_SIGN_DSA, 512) #generate new DSA key
     >>> print key

    **Usage**

    This class is able to read and parse the content of zone file by doing:

    >>> import ldns
    >>> zone = ldns.ldns_zone.new_frm_fp(open("zone.txt","r"), None, 0, ldns.LDNS_RR_CLASS_IN)
    >>> print zone.soa()
    example.	600	IN	SOA	example. admin.example. 2008022501 28800 7200 604800 18000
    >>> print zone.rrs()
    example.	600	IN	MX	10 mail.example.
    example.	600	IN	NS	ns1.example.
    example.	600	IN	NS	ns2.example.
    example.	600	IN	A	192.168.1.1

    The ``zone.txt`` file contains the following records::

       $ORIGIN example.
       $TTL 600

       example.        IN SOA  example. admin.example. (

                                       7200       ; retry (2 hours)

       rdfs.

       **Usage**

           test.nic.cz. is sub-domain of nic.cz.

       The following two examples show the creation of :class:`ldns_dname`
       from :class:`ldns_rdf`. The first shows the creation of

           >>> print dn
           a.ns.nic.cz.
