I'm setting up a computer with CentOS 6.4 and a mirrored software
RAID. I would like it to be encrypted so I was wondering what the best
configuration is. The only info I could find is
but it appears to be a bit old and the info on the wiki (
http://wiki.centos.org/HowTos/EncryptTmpSwapHome ) doesn't seem to
address RAIDs.

My main question is will it be better to encrypt the RAID itself or
the two partitions used by the RAID? Any other things I should be
aware of?
