Hi Peter Wang, Normally I would include your email address as recipient, but this time I can't. For some reason linux-crypto@xxxxxxxxxxxx sends me only some subset of the mails posted to the list. Your post was one of those that wasn't delivered, but I saw it listed on one of the archives. Archives don't include real email addresses, so I can't include your email address as a recipient. One possible reason why a mount could fail like that is that the gpg encrypted key file wasn't created properly, or more specifically, it was created for version of loop-AES that you were NOT running at the time the file system was created. loop-AES README section 7 attempts to explain this problem. You can try to force the on-disk version to v2 like this: gpg --decrypt </root/datakey.gpg | head -n 64 | ( sleep 60 ; gpg --symmetric -a >/root/datakey-v2.gpg ) mount -t ext3 /dev/sda8 /mnt/crypt -o loop=/dev/loop1,encryption=AES256,gpgkey=/root/datakey-v2.gpg Or, you can try to force the on-disk version to v1 like this: gpg --decrypt </root/datakey.gpg | head -n 1 | ( sleep 60 ; gpg --symmetric -a >/root/datakey-v1.gpg ) mount -t ext3 /dev/sda8 /mnt/crypt -o loop=/dev/loop1,encryption=AES256,gpgkey=/root/datakey-v1.gpg -- Jari Ruusu 1024R/3A220F51 5B 4B F9 BB D3 3F 52 E9 DB 1D EB E3 24 0E A9 DD - Linux-crypto: cryptography in and on the Linux system Archive: http://mail.nl.linux.org/linux-crypto/
