Generate a pseudo-random string in Lua

random-string.lua

-- Generate a pseudo-random string
-- If this is run more than once in the same second given by os.time(), it will generate the same string

local chars = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!@#$%^&*()_+-={}|[]`~'
local length = 40
local randomString = ''

math.randomseed(os.time())

charTable = {}
for c in chars:gmatch"." do
    table.insert(charTable, c)
end

for i = 1, length do
    randomString = randomString .. charTable[math.random(1, #charTable)]
end

print(randomString)

Wow thank you!

Thx
