klughammer / node-randomstring Goto Github PK

Hi! Would it be possible to have some short-hand charset options - or a separate option - for generating all upper or all lower random strings?

Ideally, my current use-case I want 0-9 plus A-Z (but not a-z).

Previously reported and fixed elsewhere:

If I generate a number of random strings in close enough proximity to each other, they're all turning out the same. After reading through your code, this seems like an issue inherent to crypto. Any ideas on how to, e.g., seed the crypto.randombytes function with a Date.now timestamp?

Unsure if it is due to it being Electron or running webpack-dev-server, but the catch block here runs indefinitely:

function safeRandomBytes(length) {
  while (true) {
    try {
      return randomBytes(length);
    } catch(e) {
      continue;
    }
  }
}

The fact that randombytes operates differently in Node and in the browser seems like it could be the underlying cause.

Hi,
I need random strings with alphanumberic and special characters (._-,~) as characters set

Hihi!

I am using your package in my ReactJS project and I realised when randomstring.generate() is called, somehow the site just hangs and becomes unresponsive. Importing the package had no issues, only when running it. Any idea why?

It can be replicated by creating a new react app, installing randomstring dependency and calling randomstring.generate() anywhere.

hard to find you because your git url is wrong on npmjs.org

For some reason this hangs Chrome indefinitely. Anyone else experiencing this?

Unable to use charset: ['numeric', '!'] with typescript as the charset type is written as string. It's properly working in javascript but unable to use it in typescript as the type should be a string[].

randomstring\index.d.ts: 9 should be a string[] instead of string so typescript users can use it.

Is there an option for an async version? If I understand correctly, using randomBytes() synchronously results in blocking on some platforms and could reduce performance for a busy server.

Feature request:

Generate gory gory unicode.

Prior art: https://www.npmjs.com/package/random-unicode.

Would it be hard to add special characters like !@#$%^ to the charset?

#FeatureRequest

Is there a solution when using a random string that has a prefix for the generated string?
For example in case I want to generate 16 random characters but they all start with "AR", is there any solution for me?
Thank you!

That second T should be Y.

numbers 0-7 are generated more often then other characters. Because the number of characters is 62. The random number from generator is 0-255. 256 is not multiple of 62.

You should replace

var index = bf.readUInt8(i) % chars.length;

with something like this:

while((random = bf.readUInt8(i++))>=248); // 248 = 4*62
index = random % 62;

to throw away the nonuniform remainder
