ecryptfs

I installed Ubuntu 12.04 with encrypted Home-directory. When I first booted I was given the option to store a key file to some Flash-drive (USB) or anything and there was a hint how to do it later. I wanted to do it later but now can't find where to find or how to generate the key file in any documentation.

So whats the command, where's the file? Ecryptfs-manger only offers me to generate a new pair.

Thanks a lot in advance
