libsodium-wrapper reports "No secure random number generator found"

[caoster]

Here is a minimal working example:

// src/index.js
import 'node:crypto';
import _sodium from 'libsodium-wrappers';

globalThis.window = undefined;
globalThis.importScripts = undefined;

export default {
	async fetch(request) {
		globalThis.window = undefined;
		globalThis.importScripts = undefined;

		await _sodium.ready;
		return new Response('Hello');
	}
};

# wrangler.toml
name = "test"
main = "src/index.js"
compatibility_date = "2023-10-25"
compatibility_flags = [ "nodejs_compat" ]
env = { }

According to the issue at miniflare, it should work with wrangler dev. However, it keeps reporting Both wasm and asm failed to loadNo secure random number generator found at (.../node_modules/libsodium-wrappers/dist/modules/libsodium-wrappers.js:1:16026) no matter how I modify the version of wrangler (with "compatibility_date" in .toml) and libsodium.

This code works neither on my computer nor with Cloudflare workers.

Hi,

I stumbled over the same issue quite recently.

I created a PR for libsodium adding support for crypto API:
jedisct1/libsodium#1401

Minimal example that works with the patch:

export default {
  async fetch(request,env,context) {    
    const _sodium = await import("libsodium-wrappers");
    await _sodium.ready;
    let binkey = _sodium.from_base64(env.PUBKEY, _sodium.base64_variants.ORIGINAL)
    console.log(binkey);
    return new Response('Hello');
  }
};

They've merged the PR, it seems working :D
