Beside, it turned out that cipher wasn't secure at all. Frequency analysis will break it, if you actually bother to try. A letter/number will be translated into a 3 digit number, and that number will remain the same throughout the whole cipher text.
If you, for amusement or out of general interest in cryptography, want to check out a really hard cipher to break, find a "one time pad" generator and a "Vigenere" encryptor. Of course, since computers are utterly unabl to generate truely random numbers, this is like I said "just" a really hard cipher to break. Get truely random numbers, and it is truely unbreakable.
