NAME

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

SYNOPSIS

9           use Net::DNS;
10           $rr = Net::DNS::RR->new('name SSHFP algorithm fptype fp');
11

DESCRIPTION

13       DNS SSH Fingerprint (SSHFP) resource records.
14

METHODS

16       The available methods are those inherited from the base class augmented
17       by the type-specific methods defined in this package.
18
19       Use of undocumented package features or direct access to internal data
20       structures is discouraged and could result in program termination or
21       other unpredictable behaviour.
22
23   algorithm
24           $algorithm = $rr->algorithm;
25           $rr->algorithm( $algorithm );
26
27       The 8-bit algorithm number describes the algorithm used to construct
28       the public key.
29
30   fptype
31           $fptype = $rr->fptype;
32           $rr->fptype( $fptype );
33
34       The 8-bit fingerprint type number describes the message-digest
35       algorithm used to calculate the fingerprint of the public key.
36
37   fingerprint
38   fp
39           $fp = $rr->fp;
40           $rr->fp( $fp );
41
42       Hexadecimal representation of the fingerprint digest.
43
44   fpbin
45           $fpbin = $rr->fpbin;
46           $rr->fpbin( $fpbin );
47
48       Returns opaque octet string representing the fingerprint digest.
49
50   babble
51           print $rr->babble;
52
53       The babble() method returns the 'BabbleBubble' representation of the
54       fingerprint if the Digest::BubbleBabble package is available, otherwise
55       an empty string is returned.
56
57       Bubble babble represents a message digest as a string of "real" words,
58       to make the fingerprint easier to remember. The "words" are not
59       necessarily real words, but they look more like words than a string of
60       hex characters.
61
62       Bubble babble fingerprinting is used by the SSH2 suite (and
63       consequently by Net::SSH::Perl, the Perl SSH implementation) to display
64       easy-to-remember key fingerprints.
65
66       The 'BubbleBabble' string is appended as a comment when the string
67       method is called.
