Re: cryptoloop confusion
Hi,
[Probably not related much to your problems, but you might find it
interesting]
If all you want is file system encryption you can try the loop-AES patche
http://loop-aes.sourceforge.net/
If used it for a long time on my laptop and it's been perfectly usable
(stable, fast to some excent, no problems when upgrading kernels, etc..). It
uses de AES cryptosystem, of proven strength . The compilation/instalation
procedure is quite easy, also
Cheers
Pedro
