    Recipe 5.14. Parallelizing Encryption and Decryption in Arbitrary Modes (Breaking Compatibility)

    5.14.1. Problem

    You are using a cipher mode that is not intrinsically parallelizable, but you have a large data set and want to take advantage of multiple processors at your disposal.

    5.14.2. Solution

    Treat the data as multiple streams of interleaved data.
