Of course I have no idea how this encryption works in openSUSE and it may just be a bug in the encryption system in 12.1 - I just don't know. All I know at the moment is what I learnt earlier today from personal experience. Sorry, I don't see what your problem is.
You have an encrypted partition. To mount it you need to give the key so the system can read it. Once its mounted it behaves like a normal file system because its the file system not the files that are encrypted.
So of course if you copy using file oriented tools like cp, rsync, cpio, tar ... which can read the files, the output will be clear.
And even if you copy with DD -- WHILE THE FILE SYSTEM IS MOUNTED - it will be in the clear.
I repeat: its the encryption at the block level, not the file level.
There is no bug in 12.1
You have no idea how encryption works ... but really you do. You've just forgotten that its the block you've encrypted not the files.
<SIGH> I said that I didn't know how the encryption worked on the home partition which v12.1 encrypted - and I damn well meant it so don't say that I "...really do"! It's only in this thread that I now discovered that there is block-level encryption and file-level encryption. Don't ever assume anything! Remember, "Assumption is the mother of all f***-ups!"
