      public PBEParameterSpec(byte[] salt, int iterationCount)
      Constructs a parameter set for password-based encryption as defined in the PKCS #5 standard.
      Parameters:
      salt - the salt. The contents of salt are copied to protect against subsequent modification.
      iterationCount - the iteration count.
      Throws:
      NullPointerException - if salt is null.
