[Pkg-cryptsetup-devel] Bug#365333: cryptsetup incompatibility

[Walter Hofmann]

Package: cryptsetup
Version: 2:1.0.2+1.0.3-rc3-1
Severity: important

I want to report on an incompatibility in cryptsetup which prevents me
from using the current version. This is possibly related to bug #364529,
but I cannot tell for sure.

I use cryptsetup to create an encrypted mapping with the following
command line

 cryptsetup -c aes-cbc-plain -s 256 create 'root' '/dev/hda1' <key

key is a file containing 64 hex digits (i.e. 256 bits) and a \n.

The old version of cryptsetup, which worked, built the mapping just as
if I had entered the key by hand. The new version seems to process the
key somewhat differently so that the data is not properly decrypted -- I
cannot mount the filesystem.

Unfortunately, I cannot say what the 'old' version of cryptsetup is. I
still have the binary, but it doesn't support the --version option. It
is a version that was in unstable around Nov 25 2005.

I already tried to make it work by:
 - using "-d key" on the command line and
 - removing the trailing newline in the key file
but this didn't help. 
Typing in the key on the command line still works.
