CryptoJS 3.x AES encryption/decryption on client side with Javascript and on server side with PHP

I've long researched to make this working for me and i want to share my solution to make it possible to encrypt/decrypt data from/to CryptoJS and PHP. This works with CryptoJS 3.x and PHP with openssl support.

I use a JSON format for encryption/decryption to be able to use any possible object/array/string data on both sides. I also use the standard AES implementation from CryptoJS with a passphrase. I don't generate special keys, iv's or salts.

Requirements

• PHP 5.4+ or higher
• PHP with OpenSSL Support: http://php.net/manual/en/openssl.installation.php
