function user_needs_new_hash in Acquia Connector 6.2

Check whether a user's hashed password needs to be replaced with a new hash.

This is typically called during the login process when the plain text password is available. A new hash is needed when the desired iteration count has changed through a change in the variable password_count_log2 or DRUPAL_HASH_COUNT or if the user's password hash was generated in an update like user_update_7000().

Alternative implementations of this function might use other criteria based on the fields in $account.

Parameters

$account: A user object with at least the fields from the {users} table.

Return value

TRUE or FALSE.

Code

function user_needs_new_hash($account) {

  // Check whether this was an updated password.
  if (substr($account->pass, 0, 3) != '$S$' || strlen($account->pass) != DRUPAL_HASH_LENGTH) {
    return TRUE;
  }

  // Check whether the iteration count used differs from the standard number.
  return _password_get_count_log2($account->pass) != variable_get('password_count_log2', DRUPAL_HASH_COUNT);
