Hmm, to follow up on my previous post, it seems that the problem is not when I tried using aes as I thought, that was the one that worked originally, and after that I had tried blowfish -- and it is blowfish that blows it. I just created two different loop devices with aes and everything went fine, at least with the 128 bit key. Made one of 3000k and was able to create a reiserfs file system on that and mount it okay. -- Harmon Seaver, MLIS CyberShamanix Work 920-203-9633 hseaver@xxxxxxxxxxxxxxxxx Home 920-233-5820 hseaver@xxxxxxxxxxxxx http://www.cybershamanix.com/resume.html Linux-crypto: cryptography in and on the Linux system Archive: http://mail.nl.linux.org/linux-crypto/
