AES in linux host

Hi
I have to use AES 128 CBC in my project for each new user that wants to register in my app
In the app, the user encrypt data and send it to the host
In host, I have to decrypt it and check data is valid or not
My main question is:
For 20 requests at the moment are bad for CPU?

I would not worry about it unless you start to see a cpu performace hit on it.

Just keep an eye on it. You may want to look into using JavaScript async.

What did you Try? What did you Get? What did you Expect?

Of course, but that is important using AES is correct or not in cpanel?

This may help you.

How do you Encrypt and Decrypt a PHP String?
