.SH NAME
Net::DNS::RR::TLSA \- DNS TLSA resource record
.SH SYNOPSIS
.IX Header "SYNOPSIS"
.Vb 2
\&    use Net::DNS;
\&    $rr = Net::DNS::RR\->new(\*(Aqname TLSA usage selector matchingtype certificate\*(Aq);
.Ve
.SH DESCRIPTION
.IX Header "DESCRIPTION"
The Transport Layer Security Authentication (TLSA) DNS resource record
is used to associate a TLS server certificate or public key with the
domain name where the record is found, forming a "TLSA certificate
association".  The semantics of how the TLSA RR is interpreted are
described in RFC6698.
.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 usage
.IX Subsection "usage"
.Vb 2
\&    $usage = $rr\->usage;
\&    $rr\->usage( $usage );
.Ve
.PP
8\-bit integer value which specifies the provided association that
will be used to match the certificate presented in the TLS handshake.
.SS selector
.IX Subsection "selector"
.Vb 2
\&    $selector = $rr\->selector;
\&    $rr\->selector( $selector );
.Ve
.PP
8\-bit integer value which specifies which part of the TLS certificate
presented by the server will be matched against the association data.
.SS matchingtype
.IX Subsection "matchingtype"
.Vb 2
\&    $matchingtype = $rr\->matchingtype;
\&    $rr\->matchingtype( $matchingtype );
.Ve
.PP
8\-bit integer value which specifies how the certificate association
is presented.
.SS certificate
.IX Subsection "certificate"
.SS cert
.IX Subsection "cert"
.Vb 2
\&    $cert = $rr\->cert;
\&    $rr\->cert( $cert );
.Ve
.PP
Hexadecimal representation of the certificate data.
.SS certbin
.IX Subsection "certbin"
.Vb 2
\&    $certbin = $rr\->certbin;
\&    $rr\->certbin( $certbin );
.Ve
.PP
Binary representation of the certificate data.
.SS babble
.IX Subsection "babble"
.Vb 1
\&    print $rr\->babble;
.Ve
.PP
The \fBbabble()\fR method returns the 'BubbleBabble' representation of the
digest if the Digest::BubbleBabble package is available, otherwise
an empty string is returned.
.PP
BubbleBabble represents a message digest as a string of plausible
words, to make the digest easier to verify.  The "words" are not
necessarily real words, but they look more like words than a string
of hex characters.
.PP
The 'BubbleBabble' string is appended as a comment when the string
method is called.
