Password Encryption/ Decryption with JS/PHP

I'm looking for a skilled developer to assist in enhancing the security of our platform by implementing a password encryption and decryption system.

Encryption in javascript needs to be done using:
<script src="https://cdnjs.cloudflare.com/ajax/libs/crypto-js/4.2.0/crypto-js.min.js"></script>

Something like this?
var encryptedMessage = CryptoJS.AES.encrypt(message, secretKey).toString();

Then this value needs to be decrypted in the php backend.
