Features:

• Converts Plain text into base three binary-like numbers
• It then changes those numbers into an encrypted message the same length as the original message(includes spaces)

Planned Features:

1. encryption key for actual security against someone who doesn't have the program
2. Save output to a user-defined file
3. Change menus to look different between encrypter and decrypter

Bugs:

It would be nice if it kept capitalization, but overall not bad!

Hmm.. seems cool.

Very Cool man look forward to using it

Hey. This is a really good program but I found a bug.
1. When decrypting 'hello' all it does is encrypt it again. But, if you decrypt 'hello' and then encrypt the string that it gave you, you will get 'hello' again.

Basically, what I am saying is that the decryption program is just another encryption program that works the opposite way as the encryption program. Doing it this way makes some words, like 'hello' not work properly. When you decrypt the encryption of 'hello' (bojn) it comes up with another word.
I think you should take another look at this…

But I think it's an awesome program apart from this bug.

EDIT: I just saw in your bug section that it says about the same thing…

Instead of (line 44 - 48)

for i=1, #message do
  letter = string.sub(message,i,i)
  letter = string.lower(letter)
  table.insert(word,characters[letter])
end

it can be

for i=1, #message do
  table.insert(word,characters[message:sub(i,i):lower()])
end

Nice crypt thingy :P/>

Your code is a mess, use local variables! I can't say if changing it won't break anything…
