.SH NAME
Net::DNS::RR::NSEC3PARAM \- DNS NSEC3PARAM resource record
.SH SYNOPSIS
.IX Header "SYNOPSIS"
.Vb 2
\&    use Net::DNS;
\&    $rr = Net::DNS::RR\->new(\*(Aqname NSEC3PARAM algorithm flags iterations salt\*(Aq);
.Ve
.SH DESCRIPTION
.IX Header "DESCRIPTION"
Class for DNSSEC NSEC3PARAM resource records.
.PP
The NSEC3PARAM RR contains the NSEC3 parameters (hash algorithm,
flags, iterations and salt) needed to calculate hashed ownernames.
.PP
The presence of an NSEC3PARAM RR at a zone apex indicates that the
specified parameters may be used by authoritative servers to choose
an appropriate set of NSEC3 records for negative responses.
.PP
The NSEC3PARAM RR is not used by validators or resolvers.
.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 Hash Algorithm field is represented as an unsigned decimal
integer.  The value has a maximum of 255.
.SS flags
.IX Subsection "flags"
.Vb 2
\&    $flags = $rr\->flags;
\&    $rr\->flags( $flags );
.Ve
.PP
The Flags field is represented as an unsigned decimal integer.
The value has a maximum of 255.
.SS iterations
.IX Subsection "iterations"
.Vb 2
\&    $iterations = $rr\->iterations;
\&    $rr\->iterations( $iterations );
.Ve
.PP
The Iterations field is represented as an unsigned decimal
integer.  The value is between 0 and 65535, inclusive.
.SS salt
.IX Subsection "salt"
.Vb 2
\&    $salt = $rr\->salt;
\&    $rr\->salt( $salt );
.Ve
.PP
The Salt field is represented as a contiguous sequence of hexadecimal
digits. A "\-" (unquoted) is used in string format to indicate that the
salt field is absent.
.SS saltbin
.IX Subsection "saltbin"
.Vb 2
\&    $saltbin = $rr\->saltbin;
\&    $rr\->saltbin( $saltbin );
.Ve
.PP
The Salt field as a sequence of octets.
