NAME

6       Net::DNS::RR::TLSA - DNS TLSA resource record
7

SYNOPSIS

9           use Net::DNS;
10           $rr = Net::DNS::RR->new('name TLSA usage selector matchingtype certificate');
11

DESCRIPTION

13       The Transport Layer Security Authentication (TLSA) DNS resource record
14       is used to associate a TLS server certificate or public key with the
15       domain name where the record is found, forming a "TLSA certificate
16       association".  The semantics of how the TLSA RR is interpreted are
17       described in RFC6698.
18

METHODS

20       The available methods are those inherited from the base class augmented
21       by the type-specific methods defined in this package.
22
23       Use of undocumented package features or direct access to internal data
24       structures is discouraged and could result in program termination or
25       other unpredictable behaviour.
26
27   usage
28           $usage = $rr->usage;
29           $rr->usage( $usage );
30
31       8-bit integer value which specifies the provided association that will
32       be used to match the certificate presented in the TLS handshake.
33
34   selector
35           $selector = $rr->selector;
36           $rr->selector( $selector );
37
38       8-bit integer value which specifies which part of the TLS certificate
39       presented by the server will be matched against the association data.
40
41   matchingtype
42           $matchingtype = $rr->matchingtype;
43           $rr->matchingtype( $matchingtype );
44
45       8-bit integer value which specifies how the certificate association is
46       presented.
47
48   certificate
49   cert
50           $cert = $rr->cert;
51           $rr->cert( $cert );
52
53       Hexadecimal representation of the certificate data.
54
55   certbin
56           $certbin = $rr->certbin;
57           $rr->certbin( $certbin );
58
59       Binary representation of the certificate data.
60
61   babble
62           print $rr->babble;
63
64       The babble() method returns the 'BubbleBabble' representation of the
65       digest if the Digest::BubbleBabble package is available, otherwise an
66       empty string is returned.
67
68       BubbleBabble represents a message digest as a string of plausible
69       words, to make the digest easier to verify.  The "words" are not
70       necessarily real words, but they look more like words than a string of
71       hex characters.
72
73       The 'BubbleBabble' string is appended as a comment when the string
74       method is called.
