Secure password hashing functions for user authentication.

Code

  // Check whether this was an updated password.
  if ((substr($account->password, 0, 3) != '$S$') || (strlen($account->password) != FP_HASH_LENGTH)) {

  }
  // Ensure that $count_log2 is within set bounds.
  $count_log2 = _password_enforce_log2_boundaries(variable_get('password_count_log2', FP_HASH_COUNT));
  // Check whether the iteration count used differs from the standard number.
  return (_password_get_count_log2($account->password) !== $count_log2);
