Hello all,<br><br>I'm trying to create an encrypted loopback filesystem, but it bombs when<br>I run the command:<br><br># losetup -e aes256 /dev/loop0 `pwd`/file.bin<br>ioctl: LOOP_SET_STATUS: Invalid argument, requested cipher or key length
<br>(256 bits) not supported by kernel.<br><br>I also tried aes (without the 256) with the same results:<br>ioctl: LOOP_SET_STATUS: Invalid argument, requested cipher or key length<br>(128 bits) not supported by kernel.<br>
<br>I am running the 2.6.20-16-generic kernel, I have loop-aes-utils<br>installed, and I have both the loop and aes modules loaded.<br><br>When I type 'cat /proc/crypto', I get for aes:<br>min keysize : 16<br>max keysize : 32
<br><br>I did a search but it turned up nothing useful -- everything I found<br>simply said to install the loop-aes-utils package, which I already have.<br><br>Can anyone tell me what I have wrong?<br><br>--<br>ubuntu-users mailing list
