I'd like to setup a cryptographic filesystem using the loopback device in combination with ext2 fs.
Which of the crypto codecs supplied by the international kernel patch should I choose to get a secure but still fast fs ?
Are there other crypto fs implementations for linux ?
There are. You will not have to do it yourself - except you have any special needs. (If you have, you might want to have a look at my homepage (sorry, in german) below "Forschung - Veröffentlichungen:" (one paper in english) -- we are developing a new group-aware crypto fs for Linux, but there is only a - unpublished - very early prototype by now.) Existing solutions (not complete): TCFS: Uses some kind of local NFS link to make encryption transparent for the user; uses repository on existing file system http://tcfs.dia.unisa.it/ PPDD: Derived from loopback device. Uses whole partition or file of fixed size http://linux01.gwdg.de/~alatham HTH Regards Johannes ----------------------------------------------------------------- Dipl.-Inform.
