Did I ask the wrong question? I haven't heard any more feedback. My last post gives an idea of the amount for brute force work it would take to break the loop-AES system. AES itself only has 256 bits maximum, but loop-AES is using 64 keys, instead of one, plus a random IV. Is dm-crypt only 256 bits secure when using AES cipher and using a USB stick with it? I'm trying to understand how the USB stick fits in for a start, and how large the master key is when operated like this. Anyone? Can't be that hard can it? --------------------------------------------------------------------- - http://www.saout.de/misc/dm-crypt/ To unsubscribe, e-mail: dm-crypt-unsubscribe@xxxxxxxx For additional commands, e-mail: dm-crypt-help@xxxxxxxx
