Make it possible to specify iteration count for salt+password hashing
---------------------------------------------------------------------

                 Key: JBSEAM-3763
                 URL: https://jira.jboss.org/jira/browse/JBSEAM-3763
             Project: Seam
          Issue Type: Feature Request
          Components: Security
         Environment: Seam 2.1 
            Reporter: Nikolay Elenkov


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() {..}

}
