The result file will be nearly the same size as the original... In fact,
it will be rounded to the nearest bigger multiple of the cipher block
size. For example, if you use 3DES, the block size is 8 bytes, your
ciphered file will be rounded to the next multiple of 8 bytes (if it's
already a multiple of 8, then just add 8, there's ALWAYS a padding).
