If you actually want to see the linux loopback code I mentioned, here's the real announcement. _Mark_ ------- Start of forwarded message ------- From: almesber@nessie.cs.id.ethz.ch (Werner Almesberger) Newsgroups: comp.os.linux.announce Subject: New loop devices, even with DES encryption Keywords: loop devices, DES, mount regular files Date: 1 Jun 93 20:13:47 GMT Followup-To: comp.os.linux Organization: Swiss Federal Institute of Technology (ETH), Zurich, CH Version 0 of the new loop devices patch is in tsx-11.mit.edu:/pub/linux/BETA/loop and nic.funet.fi:/pub/OS/Linux/BETA/loop The files are: lo.0.tar.z The loop devices patch des.0.tar.z DES-encryption for the kernel Note: If you're FTPing from outside the U.S. or Canada, please get the DES patch from nic.funet.fi, because of the well-known US export restrictions. (DES encryption is optional. The loop devices also work without it.) Loop devices give you the ability to mount file systems from regular files. Additionally, you can use them to have more than one file system on one partition and to have transparent on-line encryption of all your data. The loop devices patch is relative to ALPHA 0.99pl10, but it'll probably work with 0.99pl9 and 0.99pl10 too. The DES patch should work with any recent kernel. This is a new implementation of loop devices by Theodore Ts'o, I'm just maintaining the code. Unlike my old loop devices, which are also in some versions of SLS, the new loop devices will continue to work after variable block sizes are added to the kernel. The DES code is derived from Eric Young's DES library. I originally wanted to use UFC crypt, but its memory requirements make it a bit difficult to handle. Maybe later. - Werner -- _________________________________________________________________________ / Werner Almesberger, ETH Zuerich, CH almesber@nessie.cs.id.ethz.ch / /_IFW_A44__Tel._+41_1_254_7213__________________almesber@bernina.ethz.ch_/ ------- End of forwarded message -------
