> The current default implementation of password hashing hashes the salt and password only one time. Since having a number of iterations when generating the hash value is a generally accepted security practice (Cf. PKCS#5), it would be nice if one could specify the iteration count as a parameter to UserPassword. 
> Suggestion:
> Add an 'iterationCount' attribute to the UserPassword annotation.
> Example usage:
> class User {
>   @UserPassword(hash="sha1", iterationCount=1000)
>   String getPasswordHash() {..}
> }
