Random String Generator

[HauntedAlaskan]

For some reason, Roblox doesn’t allow you to generate a random string without using a script. To save you some time, I have created one for you:

Example:

local module = require(script.RandomStringGen)
local key = module.Stringify(20, 3)
print(key)

Explanation:

This module consists of two parts:

1. The first integer value specifies the desired length of the string (in this case, it is set to 20).

2. The second integer value determines the composition of the string. Here are the available options:
   1 = Uppercase letters only
   2 = Uppercase and lowercase letters only
   3 = Uppercase letters, lowercase letters, and numbers

That’s all! Please let me know if you encounter any issues or have any suggestions.

This is my first time making a post like this so please leave constructive criticism

What is the use case for this?

[HauntedAlaskan]

I personally use it as a Discord to Roblox verifier (kinda like bloxlink.) It’s extremally useful for generating one-time keys.

Just by looking at the source code, this is a lot longer than it has to be. Realistically, it’s as simple as this:

local ValidCharacters = {"a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z", "A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z", "0", "1", "2", "3", "4", "5", "6", "7", "8", "9"}
local String = ``
for i = 1, len do
	String = String..ValidCharacters[math.random(1,#ValidCharacters)]
end

very true, I should probably update my random generator to use this as well.

I have shortened this resource down to two lines of code:

local http = game:FindService("HttpService")
local str = http:GenerateGUID()

[HauntedAlaskan]

To be fair, I implemented a couple other features; but I completely get your point. I got the letters using their ASCII values because for some reason my brain at 4am thought it’d be way simpler than actually typing each character out one by one.

[HauntedAlaskan]

I didn’t even know that existed, damn.

[paswa (Hello)]

string.split it. Dont type that all out in a table

[SubtotalAnt8185]

Actually, the best option is to use string:sub.

[COUNTYL1MITS (wil)]

Why not utilize math.random() and pass the resulting number into the string.char() method instead of manually typing out all possible characters?

[CodedJer (Jeremy)]

Alternatively you could just do

local String = ""

for _ = 0, Length do
   String = String .. string.char(math.random(97, 122))
end

My face when

local RandomString = (function() local t = {}; for i = 0, math.random(0, 1000) do table.insert(t, utf8.char(math.random(1, 1114111))) end; return table.concat(t, ""); end)()

Readable code be like

local randomString = game:GetService("HttpService"):GenerateGUID()

[HexadecimalLiker (Liker)]

This is a GUID, not a random string since it has the {} and dashes (i forgot the name mbmb)

if you want a TRULY random string, use the utf8 library

[SillyMeTimbers (Silly)]

local randomString = string.gsub(game:GetService("HttpService"):GenerateGUID(false), "-", "")

[HexadecimalLiker (Liker)]

As I said, it isn’t truly random as it only uses letters and numbers

What you are showing me is called an UUID

You don’t really have a random string. Though a UUID for keys is great!
But for a truly random string, utf8 has WAYYYY MORE CHARACTERS than a GUID.

[SubtotalAnt8185]

That is technically three lines. I’m assuming that is a unicode random generator.

This seems very useful for procedural tags and such, I’ll probably be using this for future projects.
