Tim: Well this is the one area in which loop-aes is not a winner, and at least for me it does create a problem (as I have need for encrypted CD-ROMs which are readable under Linux and Windows). I am not enough of a Windows programmer to port it myself (or I would gladly). I know if I spent the time to learn how to do programming in the Windows environment enough to write a driver to read an encrypted filesystem I could certainly do it. The problem is I do not have the time to dedicate to such a project, and I presume Jari is in the same boat with respect to his programming abilities, or something makes me think he would have already written it. I am however working a friend to try to get the information to build such a port, as I think there is definite demand for it. Do not get me wrong, I like being a Linux bigot as much as the next guy, but there comes a point when one must own up to the fact that using Windows is part of working in the business world, and so therefore I am relegated to doing so in certain circumstances. Do not get me wrong, I have great appreciation for loop-aes as a piece of software, and Jari has done nothing less than a masterful job of writing it. I just would like to see it support Windows. I am trying to find a public domain driver for Windows which implements ext2 or ext3 under Windows. Then I would modify it to read using the encryption / decryption techniques used by loop-aes.

I just tried yesterday burning an encrypted image to a CD using Nero in Win NT 4.0 and it failed, but I think that's due to the software. It seems like it needs an ISO image to burn correctly. As for using the CDs under Windows, I don't think you would need a virtual Linux filesystem, you can simply create a FAT32 image (mkdosfs -F 32 image.img), rather than an ext2 one (although there is a performance hit for this, and I would love ext2 for Windows ;). Don't try burning a FAT32 image onto a CD though yet, I've never gotten windows to recognize the CD, I think it expects an ISO CD, and won't mount a FAT32 one. Windows loop-aes might need to address this? If I'm wrong, somebody please let me know how to do it, the ISO filesystem is too limiting for most of what I do and I don't want to lock myself into Linux if I don't have to. -Tim "IT3 Stuart Blake Tener, USNR-R" wrote: > > Tim, et al.: > > Well now, this is quite useful information!
