NAME¶
Net::DNS::RR::SSHFP - DNS SSHFP resource record
SYNOPSIS¶
use Net::DNS;
$rr = new Net::DNS::RR('name SSHFP algorithm fptype fp');
DESCRIPTION¶
DNS SSH Fingerprint (SSHFP) resource records.
METHODS¶
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¶
$algorithm = $rr->algorithm;
$rr->algorithm( $algorithm );
The 8-bit algorithm number describes the algorithm used to construct the public
key.
fptype¶
$fptype = $rr->fptype;
$rr->fptype( $fptype );
The 8-bit fingerprint type number describes the message-digest algorithm used to
calculate the fingerprint of the public key.
$fp = $rr->fp;
$rr->fp( $fp );
Hexadecimal representation of the fingerprint digest.
fpbin¶
$fpbin = $rr->fpbin;
$rr->fpbin( $fpbin );
Returns opaque octet string representing the fingerprint digest.
babble¶
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.
