[Gloucs] How to rescue data from a encrypted filesystem

How's it encrypted? If it's LUKS, then so long as the livecd has
support for the cipher you chose, the kernel has dm-crypt support, and
there's a copy of cryptsetup-luks in easy reach, you should be able
to mount it without problem with something like:

cryptsetup luksOpen /dev/hda2 rescue
<enter password>
mount /dev/mapper/rescue /mnt/rescue

Of course, if the partition was damaged in some way, then I don't
expect you could get anything from it at all.
