As far as I know "neural" and "cryptography" are words that are
never used together except in the context of snake-oil.

The issue is that neural systems are a heuristic optimization.
Cryptography means systems that are specifically designed so that
no possible heuristic (nor, indeed, any known computing algorithm
whatsoever, in the absence of the key) can make useful headway.

If neural anything can identify a single statistical trend to train
itself to find, then any cryptography it can find such a pattern in
is hopelessly broken.
