Specifies the number of times to apply the hash function (which is specified by the derby.authentication.builtin.algorithm property) on the credentials. Iteration slows down attackers by forcing them to spend more time calculating hashes.
This property is in effect only if NATIVE or BUILTIN authentication is specified by the derby.authentication.provider property and if the derby.authentication.builtin.algorithm property has a non-null value.
The minimum value is 1.
