Net::DNS::RR::NSEC3PARAM \- DNS NSEC3PARAM resource record
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\f(CW\*(C`use Net::DNS::RR;\*(C'\fR
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Class for \s-1DNS\s0 Address (\s-1NSEC3PARAM\s0) resource records.
.PP
The \s-1NSEC3PARAM\s0 \s-1RR\s0 contains the \s-1NSEC3\s0 parameters (hash algorithm,
flags, iterations and salt) needed to calculate hashed ownernames.
The presence of an \s-1NSEC3PARAM\s0 \s-1RR\s0 at a zone apex indicates that the
specified parameters may be used by authoritative servers to choose an
appropriate set of \s-1NSEC3\s0 records for negative responses.
.SH "METHODS"
.IX Header "METHODS"
.SS "hashalgo"
.IX Subsection "hashalgo"
Reads and sets the hashalgo (hash algorithm) attribute.
.SS "flags"
.IX Subsection "flags"
Reads and sets the flag field. Check the \s-1IANA\s0 registry for valid values.
At the time of code release the only defined value was 0x00
.SS "iterations"
.IX Subsection "iterations"
Reads and sets the iterations field
.SS "salt"
.IX Subsection "salt"
Reads and sets the salt value. Accepts and returns a string with a
number in hexadecimal notation.
