What is the recommended way to set up part of a USB volume as an encrypted volume, so that I can back up those few of my files that actually contain secrets? This is not a backup over the net. I have no need to encrypt the data transmission. I already back up the bulk of my files transparently (so as not to lose the data by losing an encryption key). I just need to encrypt a few of them -- a file here and there, and a directory or two. -- hendrik
