 Commands to setup crypted partition:
-  cryptsetup -c aes-xts-plain64 --key-size 512 --hash sha512 -y luksFormat /dev/mmcblk0p2
+  openssl enc -aes-256-ctr -pass pass:"$(dd if=/dev/urandom bs=128 count=1 2>/dev/null | base64)" -nosalt < /dev/zero > /dev/mmcblk0_foo
-  cryptsetup luksClose /dev/mapper/sdhome
+  cryptsetup -c aes-xts-plain64 --key-size 512 --hash sha512 -y luksFormat /dev/mmcblk0p2
+  cryptsetup luksOpen /dev/mmcblk0p2 sdhome
   mkfs.ext4 -j -m 1 -O dir_index,filetype -L homecrypt /dev/mapper/sdhome
+Note: on a old android device i used these settings, because the kernel does not support the cipher above:
+  cryptsetup luksDump ...
+  Cipher name:    twofish
+  Cipher mode:    cbc-plain
+  Hash spec:      sha1
+Test:
+  mount /dev/mapper/sdhome /mnt/sd/
+  # cop< stuff ..
+  umount /mnt/sd
+  cryptsetup luksClose /dev/mapper/sdhome
+  # retry
 Mount the partition in linux bootscript:
