I am looking for a linux sw that allows mounting a (usually large) file as a seprate encrypted filesystem.
IN WIndows there is a similar commercial product - safeboot vdisk.
what about linux ? I know it supports encrypted partitions, but I just want a file on the normal partition to be mountable as an encrypted fs
I followed the
Encrypted filesystem HOWTO - but Sisce I am using kernel 2.6.3-4mdk and there are various cryptomodules available by default, which I loaded with modprobe, I hoped not to have to recompile the kernel - as the howto suggests.
Still, when executing
losetup -e ...
the result is invariably:
ioctl: LOOP_SET_STATUS: Invalid argument, requested cipher or key length (128 bits) not supported by kernel
what does it take to create an encrypted fs on mdk 10 ?

Are you sure that loop, cryptoloop and cryptoapi modules are loaded? Check also the man page of losetup. If there is only XOR and NONE listed as available ciphers, mandrake has not applied the necessary patch to util-linux.
