At the moment only the 26 upper case characters of the latin alphabet are allowed for the caesar algorythm, used in the crack and crypto commands, but additional characters would be useful.
0-9 would allow to easily encrypt informations like coordinates
- and _ would allow to use other word delimiters, so it becomes harder to decode
Adding these additional characters we would end up with 36 characters:
ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789-_
With more allowed characters the bruteforce attack takes longer, but 36 is not a problem. But if more players want even more allowed symbols, perhaps also lowercase, then this becomes a problem if you want a useable bruteforce attack.
Or we could do something different: Keep the 26 characters but add the 10 numbers via a parallel encryption, so you can see in the encrypted text, that at this position is a encrypted number. So, if you have a key of 3, an X encrypts to a A and a 9 encrypts to a 2. This would keep the simplicity of the algorythm, but also allows encryption of numbers.
We also could allow every other sign and keep it as it is, so it's not encrypted, like we do at the moment with the space character.

I need to think about that. Any opinions?
