i need a good encryption programe to incorperate into my game 

so could some one show some source code on how to make a good encryption programme with out using ord

thx

Making a 'good' encryption program isn't for Turing.
You can make a decent encryption (for the average user) without (don't know why you don't want to) ord just by shuffling the letters using something like 'index'.  Then when the program reads the file it unshuffles the letters in a certain way.

You may want to check some other simple encryption methods on google, I am sure there are quite a few.

Why not be a little inventive if you don't want to use 'ord' then?  Think about this...for each character that exists in a file, do you need exactly one other letter to represent it (or vice versa)?

Ah, I see.  Why not go for compression as well ;).  It would work really well, especially if it's just text files that you is doing it for.

Hint: There are only 26 (x2 if you are using cases) letters in the alphabet, and 9 numbers, thats all the data you need for a file.  The rest is just what position in the file the character is.

-----------------------------------

there are 10 munbers... unless you are using O (as in "Oh") for 0 (zero)... but I doubt that that would help much anyways. The real question is why you're trying to encript the file, and why if you feel you need to you haven't written your own ord function?

Dang!  I knew there was a mistake there somewhere :lol:.

heh, once a long time ago, i came across a DWITE Problem, something called "Cipher 2000" or was it in ECOO? I dont know. But i solved it and i quite liked the encrption so i use that type of encryption in most of my games/programs when i save some usefull data to a text file.
