Just for laughs can anyone inform me why we are now being fed monstrosity links like below?

<script src="https://code.jquery.com/jquery-3.1.1.js" integrity="sha256-16cdPddA6VdVInumRGo6IbivbERE8p7CQR3HzTBuELA=" crossorigin="anonymous"></script>

Instead of:

<script src="https://code.jquery.com/jquery-3.1.1.js"></script>

I assume they must serve some kind of purpose.

    Yes. it's important.  It's called an INTEGRITY attribute and it's there in case the CDN is ever  hacked or goes malicious.

    Integrity is a flag that can be included in script-tags that specify the hash of an accepted script.   If the script on the server does not match the hash,  the end user’s web browser will reject it  This reduces potential risk for everyone.   These days, very important.

    Crossorgin is also required for Integrity checking.  It stops credentials from being sent with the request.

    One other thing that Nancy did not mention -

    Browsers are starting to implement 'warnings' about any scripts that are from a different server than the original, without the 'integrity/origin' attribute. This is how they are 'behind the scenes' implementing html5 ad blocking.

    Like it or not, it's the world we live in now.  Hacking attempts are far more prevalent than you may realize.  Even though the sites I run are small potatoes compared to the bigger ones, I have Secure Live monitoring on my dedicated server.  In any given week, I receive between 3-5 hacking attempt warnings.  Sometimes more.  But the system stops them and then blocks their IP.  

    Some attacks originate in Russia, some from China and some from the middle east.   It's not limited to any one regions.  So if you think you're immune, think again.    Nobody is immune.

    Well Ive been doing this for what 12 years now and none of my sites have thus far been hacked......so I'll take my chances. Its like saying I'll wear a bullet proof vest everytime I go out because there is so many terrorists looking to bring you down, but I dont see many people walkng around the supermarket dressed in bomb proof jumpers.........maybe in the US because you guys do tend blow everything out of proportion.
