Exclamation Post Installation Partition Level Encryption on Redhat 5: Reopened


Hi, I've been tasked at work to look up possible solutions for partition level encryption on a pre-installed system running Redhat 5 (and unfortunately that's unchangeable) but I know little to nothing about this kind of stuff... It needs to be Free and Open source, If you have any suggestions on what to use I would greatly appreciate it.

Past that I need pros and cons of each, but I can research those on my own once I get a list of possibles, I just need a place to start... thanks

Have you ever heard of truecrypt? http://www.truecrypt.org/
Might be your best bet, if you are looking for the best encryption, etc.

I have, the problem is it needs to be Open Source...

I've found a few that I'm trying to compare, but I'm not sure which will work with RH5 yet, looks like my list that I have to narrow down is:

FREEOTFE
sm-crypt/LUKS
Cryptoloop
Loop-AES


possible scramdisk? but 4 lunix doesn't seem to have partition level encryption built in. (found out it does) Do you have any experience/advice on any of these?

edith, no my problem with scramdisk was that it doesn't allow two factor authentication, which is more of a quirk than a real problem. So it doesn't factor in until later on, after I compile a more reformed list

I use LUKS for full hard drive encryption, and then I have separate true crypt partitions. And on the contrary, truecrypt IS open source

Well I did give you the link in my first post to it

And here is a link regarding LUKS installation on RHEL - http://www.fatmin.com/2011/03/rhel-h...-and-luks.html

Now I remember why I had originally crossed TrueCrypt off of my list, it was because of the sketchiness of the domain registration and makers. This part particularly "to raise suspicions about the provenance of the product and speculate about the possible existence of vulnerabilities or backdoors that might exist in the source code or executables." I proposed it and Luks side-by-side (and because of the nature of my work, and the original trademark being registered in Czech Republic, they decided luks was going to be the safer bet) and they agreed to do luks, so we're running that right now...

I just had a quick question on it...

If I have multiple passwords on luks, is there a way to set it up so that every user has their own location that no one else can access (master key access is ok, I'd just not like one compromised pass to lead to the whole system being compromised...)?
