Example of how to sign a message with web3 and recover the address that signed it

	var ethUtil = require('ethereumjs-util');

	var data = 'Login';
	var message = ethUtil.toBuffer(data);
	var msgHash = ethUtil.hashPersonalMessage(message);

	var privateKey = new Buffer('62debf78d596673bce224a85a90da5aecf6e781d9aadcaedd4f65586cfe670d2', "hex")
	var sig = ethUtil.ecsign(msgHash, privateKey);

	var signature = ethUtil.toBuffer(sig)
