## Name

nsec3hash — generate NSEC3 hash

## Synopsis

`nsec3hash` {`salt`} {`algorithm`} {`iterations`} {`domain`}

## DESCRIPTION

nsec3hash generates an NSEC3 hash based on a set of NSEC3 parameters. This can be used to check the validity of NSEC3 records in a signed zone.

## ARGUMENTS

salt

  The salt provided to the hash algorithm.

algorithm

  A number indicating the hash algorithm. Currently the only supported hash algorithm for NSEC3 is SHA-1, which is indicated by the number 1; consequently "1" is the only useful value for this argument.

iterations

  The number of additional times the hash should be performed.

domain

  The domain name to be hashed.
