As you may have understood, in plain mode, there is no header, so no way for cryptsetup to guess the algorithm used. Thus, if it is a non-default one, it must be specified also at mount time.


Hm, makes sense. Is there some kind of a config file that I could specify the parameters in, and that would be read prior to using the defaults - similar to how some parameters for mount can be specified in /etc/fstab ?
