Re: decryption algorithm

A couple of thoughts.

1. Is what you're doing legal? These days, reverse engineering is of
dubious legality in many jurisdictions. If it's illegal in your area,
you may be asking others to help you break the law (probably not an
earth-shattering situation but ynk).

2. I suggest looking at every letter of the alphabet in binary form
(it's a lot easier to spot patterns that way). Same thing holds for
diphthongs of interest.
