LXR - cryptographic data archive
In the settings of LXR we can choose between 16 and 256 slices per encryption buffer. This is equivalent to a memory of 4 MB to 64 MB.
Now, assuming we have already encrypted 1 GB of data. This has resulted in 4096 (or 212) slices or extracted files on disk (this is the value of N in the graphics below). If one would select k=16 slices from these 4096 in the correct order, then one would need to test 2150 combinations, also written as 1’000’000’000’000’000’000’000’000’000’000’000’000’000’000’000.
This number grows quickly as we require more slices to form a larger buffer, as can be seen from the graphics below.
