Yeah. On top of the cost of getting a number from the cryptographically secure random number generator, I don't think using mod instead of and will cost that much. I'll make the change. We could add a few more characters ("-_@", probably others), but I think digits+letters is already a good improvement to what we currently have, without having to worry about file systems not liking some characters.
