PHP (Laravel) decrypt what CryptoJS encrypt about cryptojs-aes-php HOT 1 CLOSED

Hi.

This is not a problem with this library. I can't help you. I do not provide code support for applications that i don't have written.

But, to give you some hints nonetheless:

• cryptojs.encrypt is no default part of CryptoJS. First, original cryptojs variable called CryptoJS, not lowercase as in your code example. So it seems your old application have implemented a custom method to encrypt.
• So also "AES" is not default of the global namespace. It's originally inside CryptoJS, like CryptoJS.AES. So another thing that seems to have a custom imlementation in your old project
• You need to check what the old application really do with cryptojs.encrypt. What AES mode is used (aes-256-cbc or other).
• Then use the exact same method in php (as you already have tried with the check function).
• Verify what the out of JS is, then you must extract the correct parts in php
• Usually a AES-256-CBC cipher has 3 parts. encryptedValue, salt and initialization vector. The last 2 are usually generated along with the encrypted text

You will find all this parts and how they work together in my library for PHP and JS.

That's all, i will not provide more support here.

Have a nice day.
