Research direction

Start with browser.js at the linked implementation and reproduce the failure by using randombytes@2.1.0 in a browser environment built with Vite. Trace the browser-side crypto initialization and verify that the build no longer raises "global is not defined" while still accessing the browser crypto implementation.

Written by the indexing model from the issue text.

Description

When using randombytes@2.1.0 in a browser environment with Vite as the build tool, the following error occurs:

Uncaught ReferenceError: global is not defined

This error stems from the browser.js implementation attempting to access the global object which is not available in browser DOM environments:

var Buffer = require('safe-buffer').Buffer
var crypto = global.crypto || global.msCrypto

As the source code mentioned below crypto is defined correctly
