Mitigate cache-timing attack in CBC mode. This is done by implementing
...
compressed tables (2x compression factor) and by pre-fetching them into
processor cache prior every CBC en-/decryption pass. One can argue why
just CBC? Well, it's commonly used mode in real-life applications and
API allows us to amortize the prefetch costs for larger data chunks...
