does anyone know if it is possible, with the WD My Cloud device, to setup an encrypted virtual volume/drive?
I mean, an image file, which can be mounted from Linux as a file system and which is encrypted on the flight.
I’ve tried these instructions: http://encryptionhowto.sourceforge.net/Encryption-HOWTO-4.html, but I couldn’t even mount a non-encrypted device:
WDMyCloud:~/tmp# losetup /dev/loop0 $(pwd)/crypto.img /dev/loop0: No such device or address WDMyCloud:~/tmp#
The same with the -e option (tried serpent, twofish, blowfish, aes). It seems that the loop module isn’t available in this device’s kernel (‘modprobe loop’ fails and a ‘find’ under /lib/modules can’t find anything like *loop*).
Thanks in advance for any help.
