I have a virtualized linux system (vserver) that gives me all root privileges except manipulation of kernel modules. Now I wish to have a solution similar to TrueCrypt where I can create an encrypted container that I can mount as a drive. Unfortunately TrueCrypt requires me to load kernel modules which I cannot do (also FUSE is not an option).
Which alternatives do I have to encrypt a container on a system with some standard kernel modules and no means to dynamically load any more?
