[pkg-cryptsetup-devel] Bug#471729: cryptsetup: crude solution

[Christian Pernegger]

Package: cryptsetup
Version: 2:1.0.6-6
Followup-For: Bug #471729


In the end, I did this:

#!/bin/sh

#set -x 

UUID= # UUID of the USB stick's fs here

UUID_PATH="/dev/disk/by-uuid/$UUID"
MNT_DIR="/usb-key"
KEYFILE="$MNT_DIR/$1"

IN_FD="/proc/self/fd/2"

if ! lsmod | grep -q usb_storage; then
    echo >&2 "Loading USB support ..."
    modprobe usb-storage
    sleep 5
    udevsettle
fi

MOUNTED=0

if [ -b "$UUID_PATH" ]; then
    mkdir "$MNT_DIR" && mount -t ext2 -o ro "$UUID_PATH" "$MNT_DIR" && MOUNTED=1
fi

if [ $MOUNTED -eq 1 -a -e "$KEYFILE" ] ; then
    cat "$KEYFILE"
else
    echo >&2 "Key $1 not found, please enter fallback passphrase:"
    stty <$IN_FD -echo
    read <$IN_FD -rs -t 10 key
    stty <$IN_FD echo
    echo -n $key
fi

if [ $MOUNTED -eq 1 ] ; then
    umount "$MNT_DIR"
    rmdir "$MNT_DIR"
fi
