Jeezus. Didn't understand any of that

You guys didn't really understand my thing tho. You see, you assume that all the h's are the same. I'm not really that stpid(I think) The h gets a different number assigned to it each time. Sometimes it has the same time assigned. Its completely random, and it has a 1000 numbers to choose from. Therefore, a small encrypted message of

hello world i am a little bit of encrypted text with a bad algo

can look like:

99 12 43 20 19 48 67 23 10...

no repetitions for a veeeery long time, since it has a 1000 numbers for each letter. How are you gonna crack something like that, if its just a random sequence of numbers with no repetition?

However, there are always geniuses who can crack such messages in surprisingly short times, with intuition, tricks, heuristics, trial and error and lots of calculations.

Yep, I suspect the blokes over at the NSA will make piecemeal of this, but consider: as long as you update the keys regularly, and keep them huge, and the encrypted text small, it offers some pretty nice security... impractical for large corporations that want to keep millions of papers daily secure tho...
