Hi all, I've a question for you. This is how I encrypt a file: head -c 2925 /dev/random | uuencode -m - | head -n 66 | tail -n 65 \ | gpg --symmetric -a >/tmp/keyfile.gpg dd if=/dev/zero of=/tmp/file.img bs=1M count=10 head -c 15 /dev/urandom | uuencode -m - | head -n 2 | tail -n 1 \ | losetup -e AES256 -K /tmp/keyfile.gpg /dev/loop1 /tmp/file.img mkfs.ext2 /dev/loop1 mount /dev/loop1 /mnt/crypt (This is my complete procedure, please check it out :) ) I want to use two different keys for encryption the single file, but one key must be have a time-limit validity. Is it possibile? Thanks in advance for the help. - Linux-crypto: cryptography in and on the Linux system Archive: http://mail.nl.linux.org/linux-crypto/
