Loop device is a layer between filesystem and disk driver. Software encryption has some overhead, but on my primary system speed of AES is faster than what my disk can transfer. > a) LOOP-AES is implemented > b) A filesystem is placed onto a loop device > c) Wont increasing the size of the physical file affect the encryption?
