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

    use Net::DNS;
    $rr = new Net::DNS::RR('name SSHFP algorithm fptype fp');

DNS SSH Fingerprint (SSHFP) resource records.

The available methods are those inherited from the base class augmented by the type-specific methods defined in this package.

Use of undocumented package features or direct access to internal data structures is discouraged and could result in program termination or other unpredictable behaviour.

    $algorithm = $rr->algorithm;

The 8-bit algorithm number describes the algorithm used to construct the public key.

    $fptype = $rr->fptype;

The 8-bit fingerprint type number describes the message-digest algorithm used to calculate the fingerprint of the public key.

    $fp = $rr->fp;

Hexadecimal representation of the fingerprint digest.

    $fpbin = $rr->fpbin;

Returns opaque octet string representing the fingerprint digest.

    print $rr->babble;

The babble() method returns the 'BabbleBubble' representation of the fingerprint if the Digest::BubbleBabble package is available, otherwise an empty string is returned.

Bubble babble represents a message digest as a string of "real" words, to make the fingerprint easier to remember. The "words" are not necessarily real words, but they look more like words than a string of hex characters.

Bubble babble fingerprinting is used by the SSH2 suite (and consequently by Net::SSH::Perl, the Perl SSH implementation) to display easy-to-remember key fingerprints.

The 'BubbleBabble' string is appended as a comment to the RDATA when the string method is called.
