用PHP加密URL参数并用Javascript解密

Question

I have the following situation - online coloring pages that work in JavaScript. I'll be passing the coloring image URI to the script. I'd like to encrypt that URI somehow so that it's not that easy for bots to download my coloring images:

http://01smile.com/products/games/html5games/coloringbook_3%28mass%20parameter%20beta%29/index.html?i=http://01smile.com/products/games/girl.gif&p=http://01smile.com/products/games/paper.png

So the above link will be pasted on a page generated with PHP.

What encryption procedure could I use in PHP to encrypt the image URI that would I then be able to decrypt in JavaScript? I'm not looking for some high level of security - just to deter scraper bots.

You can use Base64 encoding https://en.wikipedia.org/wiki/Base64

PHP - https://php.net/manual/ru/function.base64-decode.php https://php.net/manual/ru/function.base64-encode.php

JS - https://developer.mozilla.org/en-US/docs/Web/API/WindowBase64.btoa https://developer.mozilla.org/en-US/docs/Web/API/WindowBase64.atob
