Does this allow me to turn a long string >32 chars to a UINT256? uint256 zeroValue = uint256(keccak256(abi.encodePacked(groupId))) >> 8;

npm install crypto-browserify

Edit

node_modules/react-scripts/config/webpack.config.js

insert in file around line 348:

plugins: [

... ], fallback: { "crypto": false, "crypto-browserify": require.resolve('crypto-browserify'), }

webpack.config.js:

  fallback: {
    "crypto": require.resolve('crypto-browserify'),
    "crypto-browserify": require.resolve('crypto-browserify'),
    "path": require.resolve("path-browserify"),
    "os": require.resolve("os-browserify/browser"),
    "fs": require.resolve('browserify-fs'),
    "stream": require.resolve("stream-browserify"),
  }


  Craco.config.js is now:

  const webpack = require('webpack');

module.exports = { webpack: { plugins: { add: [ // new webpack.ProvidePlugin({ // process: 'process/browser.js', // }) new webpack.ProvidePlugin({ Buffer: ['buffer', 'Buffer'], }), new webpack.ProvidePlugin({ process: 'process/browser', }), ] }, configure: { module: { rules: [ { test: /.m?js$/, resolve: { fullySpecified: false, }, }, ], }, }, }, };
