Password Generator

This script was created as a request from my friend.
The script will randomly print a string of chosen length or random if the argument says "ran", of random letters, numbers and basic symbols.

local args = {...}
local chars = {"a", "A", "b", "B", "c", "C", "d", "D", "e", "E", "f", "F", "g", "G", "h", "H", "i", "I", "j", "J", "k", "K", "l", "L", "m", "M", "n", "N", "o", "O", "p", "P", "q", "Q", "r", "R", "s", "S", "t", "T", "u", "U", "v", "V", "w", "W", "x", "X", "y", "Y", "z", "Z", "1", "2", "3", "4", "5", "6", "7", "8", "9", "0", "!", "@", "-", "_", "#", "%", "$", "*", "+"}
local pass = ""
if args[1] ~= "ran" then
  char = tonumber(args[1])
else
  char = math.random(8, 32)
end
for i = 1, char do
  local ranChar = math.random(1, #chars)
  pass = pass..chars[ranChar]
end
print(pass)

I realize this could of been done with "string.char()" however, I got lazy and I only wanted chars that ALMOST every keyboard has. You can edit out the "$" in the table if your keyboard does not support this.

Note: I do realize how simple this is however, I find it useful to use if you want to be safe. I also do not plan on updating this since it is so simple.

could be used for some encryption thing. +1

It is not encryption. This is completely random. This was designed so you can random get a password when you wanted a new account. So you run the script, write the output down in a notebook, then when ever you need to login you just look at the notebook. This is meant to make password hard to bruteforce, due to the fact that it is completely random.

I keep getting a error at
for i = 1, char do
how do you fix this

Try this.

Locked upon request.
