encrypted filesystem without loopback device and fuse - possible?
 

Hi!

I'm using a virtual host where I cannot change the kernel and they have neither loopback device nor FUSE in it. is there any other way to (create and) use an encrypted filesystem? or does anyone know a userspace program that accesses an (encrypted) filesystem image and allows copying into and out of it?


thanks,
Nils

Yes, it is possible. In fact it is now preferred. There is a new driver called dm-crypt. It works with device mapper. Here is some information.

Here is a discussion about cryptoloop vs. dm-crypt. It says that even the cryptoloop maintainer prefers dm-crypt.

but again that requires being able to configure the kernel. they still run on a 2.4 kernel, so that is out of question too.. I think my only possibility is some userspace programm..

Maybe with gpg? But the usage will be a pain
