This program attempts to decrypt English text encrypted by Malte's Easy Encryption API without knowing the key, only the key length.
The message must be much larger than the key (at least 20 times, maybe more) and must be English text - this probably won't work on Lua code, unless you change rateText. The running time is approximately O(size of key * size of message).

Screenshots at different key lengths:
(the last ones show why I said the message must be many times the key length)
