Description Sergiy Borodych 2003-12-03 09:53:06 UTC

After upgrade util-linux from util-linux-2.12 to util-linux-2.12-r1
root@work portage # /sbin/losetup -e aes-cbc /dev/loop0 /dev/hda4
You must specify a key size (in bits) for use with CryptoAPI encryption.
root@work portage # /sbin/losetup -e aes-cbc -k 256 /dev/loop0 /dev/hda4
/sbin/losetup: invalid option -- k
usage:
  /sbin/losetup loop_device                                      # give info
  /sbin/losetup -d loop_device                                   # delete
  /sbin/losetup [ -e encryption ] [ -o offset ] loop_device file # setup

Comment 1 Brad House 2003-12-03 10:28:39 UTC

The proper way to do this as of 2.12 with the cryptoapi
patches is to use
-e aes-cbc-256
instead of using -k.  
You must also use 'hashalot' to generate your key,
such as
rmd160 | /sbin/losetup -e aes-cbc-256 /dev/loop0 /dev/hda4

Also, 2.12 did not have any crypto api support at all or
the -k support, so you MUST have been using 2.11z before
then for any sort of crypto support.

Thanks 
it help me under gentoo-sources-2.4.20-r9
/sbin/losetup -e aes-cbc-256 /dev/loop0 /dev/hda4

Comment 5 Sergiy Borodych 2003-12-10 01:01:52 UTC

After installing gentoo-sources-2.4.22-r1
I can't find 
root@work src # modprobe cryptoloop
modprobe: Can't locate module cryptoloop
(I run genkernel --config and can't find like it options)
And I can't use my crypto fs
root@work src # /sbin/losetup -e aes-cbc-256 /dev/loop0 /dev/hda4

Comment 6 Sergiy Borodych 2003-12-10 02:08:32 UTC

after aplied patch-cryptoloop-jari-2.4.22.0 on gentoo-sources-2.4.22-r1 
all works
Why this patch not include in gentoo-sources-2.4.22-r1 ???
