6 Net::DNS::SEC::Keyset - DNSSEC Keyset object class
7
9 use Net::DNS::SEC::Keyset;
10
12 A keyset is an "administrative" unit used for DNSSEC maintenance.
13
14 This class provides interfaces for creating, reading and writing
15 keysets.
16
17 Object methods are provided to extract DNSKEY, RRSIG and DS records.
18
19 Note that this class is still being developed. Attributes and methods
20 are subject to change.
21
22 new (from file)
23 $keyset = Net::DNS::SEC::Keyset->new( $filename );
24 $keyset = Net::DNS::SEC::Keyset->new( $filename, $directory );
25 die Net::DNS::SEC::Keyset->keyset_err unless $keyset;
26
27 Constructor method which reads the specified keyset file and returns a
28 keyset object.
29
30 The optional second argument specifies the filename base directory.
31
32 Sets keyset_err and returns undef on failure.
33
34 new (by signing keys)
35 $keyset = Net::DNS::SEC::Keyset->new( [@keyrr], $privatekeypath );
36 die Net::DNS::SEC::Keyset->keyset_err unless $keyset;
37
38 Creates a keyset object from the keys provided through the reference to
39 an array of Net::DNS::RR::DNSKEY objects.
40
41 The method will create and self-sign the whole keyset. The private keys
42 as generated by the BIND dnssec-keygen tool are assumed to be in the
43 current directory or, if specified, the directory indicated by
44 $privatekeypath.
45
46 Sets keyset_err and returns undef on failure.
47
48 new (from key and sig RRsets)
49 $keyset = Net::DNS::Keyset->new( [@keyrr], [@sigrr] );
50 die Net::DNS::SEC::Keyset->keyset_err unless $keyset;
51
52 Creates a keyset object from the keys provided through the references
53 to arrays of Net::DNS::RR::DNSKEY and Net::DNS::RR::RRSIG objects.
54
55 Sets keyset_err and returns undef on failure.
56
57 new (from Packet)
58 $resolver = Net::DNS::Resolver->new;
59 $resolver->dnssec(1);
60
61 $reply = $res->send ( "example.com", "DNSKEY" );
62
63 $keyset = Net::DNS::SEC::Keyset->new( $reply );
64 die Net::DNS::SEC::Keyset->keyset_err unless $keyset;
65
66 Creates a keyset object from a Net::DNS::Packet that contains the
67 answer to a query for key records at the zone apex.
68
69 This is the method you should use for automatically fetching keys.
70
71 Sets keyset_err and returns undef on failure.
72
73 keys
74 @keyrr = $keyset->keys;
75
76 Returns an array of Net::DNS::RR::DNSKEY objects.
77
78 sigs
79 @sigrr = $keyset->sigs;
80
81 Returns an array of Net::DNS::RR::RRSIG objects.
82
83 extract_ds
84 @ds = $keyset->extract_ds(); # default SHA-1
85 @ds = $keyset->extract_ds( digtype => 'SHA-256' );
86 die Net::DNS::SEC::Keyset->keyset_err unless @ds;
87
88 Extracts DS records from the keyset. Note that the keyset will be
89 verified during extraction. All keys will need to have a valid self-
90 signature.
91
92 The method sets keyset_err if verification fails.
93
94 verify
95 @keytags = $keyset->verify();
96 die Net::DNS::SEC::Keyset->keyset_err unless @keytags;
97
98 $keyset->verify( $keytag ) || die $keyset->keyset_err;
99
100 If no arguments are given:
101
102 • Verifies if all signatures present verify the keyset.
103
104 • Verifies if there are DNSKEYs with the SEP flag set, there is at
105 least one RRSIG made using that key.
106
107 • Verifies that if there are no DNSKEYs with the SEP flag set there is
108 at least one RRSIG made with one of the keys from the keyset.
109
110 If an argument is given, it is should be the numeric keytag of the key
111 in the keyset which will be verified using the corresponding RRSIG.
112
113 The method returns a list of keytags of verified keys in the keyset.
114
115 The method sets keyset_err and returns empty list if verification
116 fails.
117
118 keyset_err
119 $keyset_err = Net::DNS::SEC::Keyset->keyset_err;
120
121 Returns the keyset error string.
122
123 string
124 $string = $keyset->string;
125
126 Returns a string representation of the keyset.
127
128 print
129 $keyset->print; # similar to print( $keyset->string )
130
131 Prints the keyset.
132
133 writekeyset
134 $keyset->writekeyset;
135 $keyset->writekeyset( $path );
136 $keyset->writekeyset( $prefix );
137 $keyset->writekeyset( $prefix, $path );
138
139 Writes the keyset to a file named "keyset-<domain>." in the current
140 working directory or directory defined by the optional $path argument.
141
142 The optional $prefix argument specifies the prefix that will be
143 prepended to the domain name to form the keyset filename.
