Is there a whole disk encryption software for Linux?
I am planning to install Linux on my laptop, but I am not comfortable of running my laptop without a disk encryption software such as PC Guardians. currently i am using CompuSec, but it won't work in Linux.
In case you wonder what i have on my disk, mostly me and gf and stuff. *smile.
If your kernel supports it, I had to recompile my own, you can use AES-loop encryption. I haven't used the other forms of encryption so I couldn't say how well they work, but I made a script for my live cd that would encrypt the swap, root and home partitions and create an decryption boot disc.
AES-loop encryption seemed to run quite well and I couldn't notice any real performance issuies with it
Or dm-crypt and it looks like there is a software for reading it from windows but haven't tried it.
I'm using dm-crypt since maybe 2 years, never had a problem. Half of my disk is encrypted, all my personnal datas go there. Performance can be an issue but I haven't really benchmarked it.
You could try compusec (http://www.ce-infosys.com/english/index.html). However, I have never used it myself (neither windows nor Linux) so I can't say much to it. It used to have the reputation of being pretty unreliable.
In Linux I'd really recommend to use dm_crypt for disk encryption.
Edit: Oh, in case you try compusec, please share your experience. I'd be interested to know
