function user_needs_new_hash in Simple LDAP 7
Same name and namespace in other branches
- 7.2 simple_ldap_user/simple_ldap_user.password.inc \user_needs_new_hash()
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
object $account: A user object with at least the fields from the {users} table.
Return value
boolean 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;
}
// Ensure that $count_log2 is within set bounds.
$count_log2 = _password_enforce_log2_boundaries(variable_get('password_count_log2', DRUPAL_HASH_COUNT));
// Check whether the iteration count used differs from the standard number.
return _password_get_count_log2($account->pass) !== $count_log2;
