Never read the book so not sure how integral the technical details are to the plot. But this sounds like it could be excused as a mere plot device or by appealing to the Suspension of Disbelief.
I agree it would probably be wiser narratively and aesthetically to let our hero, the Cryptographical Expert, gloss over the technical details and just say to the pushy Head Bureacrat at some point early in the novel something like, "I could try to explain this to you but I don't fully understand it myself."
The less pardonable offense where Dan Brown's writing is concerned, both in my limited experience and as others in this thread have pointed out, is the lousy writing.
