\&\s-1DNS SSH\s0 Fingerprint (\s-1SSHFP\s0) resource records.
.SH "METHODS"
.IX Header "METHODS"
The available methods are those inherited from the base class augmented
by the type-specific methods defined in this package.
.PP
Use of undocumented package features or direct access to internal data
structures is discouraged and could result in program termination or
other unpredictable behaviour.
.SS "algorithm"
.IX Subsection "algorithm"
.Vb 2
\&    $algorithm = $rr\->algorithm;
\&    $rr\->algorithm( $algorithm );
.Ve
.PP
The 8\-bit algorithm number describes the algorithm used to
construct the public key.
.SS "fptype"
.IX Subsection "fptype"
.Vb 2
\&    $fptype = $rr\->fptype;
\&    $rr\->fptype( $fptype );
.Ve
.PP
The 8\-bit fingerprint type number describes the message-digest
algorithm used to calculate the fingerprint of the public key.
.SS "fp"
.IX Subsection "fp"
.Vb 2
\&    $fp = $rr\->fp;
\&    $rr\->fp( $fp );
.Ve
.PP
Hexadecimal representation of the fingerprint digest.
.SS "fpbin"
.IX Subsection "fpbin"
.Vb 2
\&    $fpbin = $rr\->fpbin;
\&    $rr\->fpbin( $fpbin );
.Ve
.PP
Returns opaque octet string representing the fingerprint digest.
.SS "babble"
.IX Subsection "babble"
.Vb 1
\&    print $rr\->babble;
.Ve
.PP
The \fIbabble()\fR method returns the 'BabbleBubble' representation of
the fingerprint if the Digest::BubbleBabble package is available,
otherwise an empty string is returned.
.PP
Bubble babble represents a message digest as a string of \*(L"real\*(R"
words, to make the fingerprint easier to remember. The \*(L"words\*(R"
are not necessarily real words, but they look more like words
than a string of hex characters.
.PP
Bubble babble fingerprinting is used by the \s-1SSH2\s0 suite (and
consequently by Net::SSH::Perl, the Perl \s-1SSH\s0 implementation)
to display easy-to-remember key fingerprints.
.PP
The 'BubbleBabble' string is appended as a comment to the \s-1RDATA\s0
when the string method is called.
