> DERBY-5539 introduced two new properties that control how BUILTIN stores
> credentials:
> - derby.authentication.builtin.saltLength (default: 16)
> This property specifies the number of bytes of random salt that will be added
> to the credentials before hashing them. (Purpose of the property: Make it
> infeasible to construct rainbow tables.)
> - derby.authentication.builtin.iterations (default: 1000, minimum: 1)
> This property specifies the number of times to apply the hash function (which
> is specified by derby.authentication.builtin.algorithm) on the credentials.
> (Purpose of the property: Slow down attackers as they'll need to spend more
> time calculating hashes.)
> Both the properties have effect only if BUILTIN authentication is enabled and
> derby.authentication.builtin.algorithm has a non-null value.
