Create a encrypted pendrive/usb stick using cryptsetup and openluks

I've a problem to get this working again (got it working once on debian) but i switched to Arch Linux and i forgot the internet page how to get a usb stcik fully encrypted using cryptsetup and openluks.
as far as i know iI need openluks so i can also open the encrypted usb stick at my work with a windows pc using Freeofte.
can someone give me a manual or a link to a usb encrypted with archlinux using cryptsetup and openluks.

if everytthing is set up correctly (in debian) the automount function should pop up asking for a passprase when pluging in the USB in my linux box (now archlinux)

Arch Linux has excellent wiki pages, when you have a question, you should have a look at them in the first place.

Re: Create a encrypted pendrive/usb stick using cryptsetup and openluks

so i got a usb now who's asking for a passphrase, but not working on windows and or linux (seems that there is no partition (?????.)
This is what i did so far.

crypsetup --verbose -c aes-xts-plain -y -s 256 luksFormat /dev/sdb1
cryptsetup luksOpen /dev/sdb1 vault

What am i Missing?

seems that indeed a partition was not created...

i did the following

mkfs.vfat /dev/mapper/vault

cryptsetup luksClose /dev/mapper/vault

replaced the usb en accessable under linux.

Will now test it on Free OFTE on Windows......

Of course with the first step you only created an encrypted container, then (as you already did) you have to create a filesystem on the top of it, too. Now you should be able to mount that pendrive of yours.
