Use window.crypto in nodejs code

Question

Use window.crypto in nodejs code

I am trying to use the window.crypto.getRandomValues method in a nodejs script. From my understanding there is no window element when I run a simple code like this in node:

var array = new Uint32Array(10);
window.crypto.getRandomValues(array);

Which is why I get this error:

ReferenceError: window is not defined

How can I use this method in my code?

Thanks

You can use the built-in crypto module instead. It provides both a crypto.randomBytes() as well as a crypto.pseudoRandomBytes().

However it should be noted that these methods give you a Buffer object, you cannot pass in a Uint32Array or similar, so the API is a bit different.
