If you need experiment over a memory device, use either
ramdisk, scsi_debug module to it.<br>
Another alternative is to create dm-zero device and use
plain dm-crypt (not LUKS).<span class="gmail-HOEnZb"></span><br>

E.g. 10TiB "zero" mapped device (pick your name instead of 'z'):<br>
<br>
dmsetup create z --table "0 $((10*1024*1024*1024*2)) zero"<br>
<br>
Block device node for this is:<br>
<br>
/dev/mapper/z<br>
<br>
<br>
See dmsetup(8) and device-mapper target documentation in kernel
source,<br>
for instance Documentaion/device-mapper/zero.txt.<br>
