Thanks a lot for bailing me out:-) I did not know what to answer to Gisle Sælensminde. The outlook that a double layer of loop-aes could decrease security is rather shocking.
My questions and proposals never dealt with cipher analysis. I rather concentrate on things like a proper & easy to handle environment. Storing keys and tools on a usb-stick has nothing to do with strong ciphers but it is the ultimate opportunity to keep keys away from your attackers *and* encrypt all your data, not just larger parts.
As all ciphers can and will be broken I deem it important to look for alternatives on how to cover encryption. Where could the data be on a drive with no partition table? Where to start a brute force attack if there is no end and no beginning? Is it a successfull attack if you get encrypted data after you break the first layer of encryption?
I suppose and fear popular tools like truecrypt rely to much on buzzword compliant selfpromotion.
I still suppose double encryption and mixing up more than one cipher in deed does slow down attackers.

Peter
