Returns the number of requested hash iterations to be performed when computing the final {@code Hash} result.
A non-positive (0 or less) indicates that the {@code HashService}'s default iteration configuration should
be used. A positive value overrides the {@code HashService}'s configuration for a single request.
<p/>
Note that a {@code HashService} is free to ignore this number if it determines the number is not sufficient
to meet a desired level of security.
