The type Tiqr_UserStorage_Encryption_Interface was not found. Maybe you did not declare it correctly or list all dependencies?

The expression return $instance also could return the type Tiqr_UserSecretStorage_Encryption_Dummy|Tiqr_UserSecretStorage_Encryption_Mcrypt which is incompatible with the documented return type Tiqr_UserStorage_Encryption_Interface.
