Missing crypto polyfills from the iife build about snarkjs HOT 3 CLOSED

The issue is solved in my case by changing the build file output.globals to

globals: {
            os: "null",
            "crypto": "cryptoBrowserify"
        },

and removing crypto: empty from the virtual plugin and rebuilding snarkjs.min.js

Then create a cryptoBrowserify global variable externally, when I use the dependency.

Buffer.from is also not supported by the browser

https://github.com/iden3/snarkjs/blob/master/src/misc.js#L126

and so to make it work another dependency "buffer" is used and Buffer must be also available in the global scope.

I hope somebody else finds it useful. This solved my issue.

@StrawberryChocolateFudge I have a proper PR at #364 that you could use instead. And I'll be submitting a PR that adds browser testing for this in a minute.

Very cool! I will try it :)
