I managed to a get an encrypted filesystem using cryptoAPI on the kernel 2.4.x series. I've been looking around for more info but all I get are just HOWTOs to set it up but not a "HOWTO make use of it" type of document.
steps I followed...everything has been patched, I get no errors, no nothing...so it's all good.
dd if=/dev/urandom of=testFile bs=1M count=20
losetup -e idea /dev/loop0 testFile
mkfs -t ext2 /dev/loop0
#creating mount point dir
mount -o loop,encryption=idea testFile /home/frodo/ctest
so now ....my /home/frodo/ctest has a lost+found dir inside and everything...
of course, the test file is still encrypted.
1. Now should I just dump data into the directory created? if not there, where?
2. All data should be encrypted right away? I did a test by creating a clear text file named XFILE on the ctest dir but I still can see it in plain text from a different computer on the network. Did I do anything wrong?
3. or All the data I dump into the ctest directory is in turn dumped into the testFile encrypted file? if so...can I just delete the XFILE clear text file?
