Asking about Mcrypt PHP decryption and arabic JSON support

Hi Team,
I has a project which has encrypted JSON with PHP Mcrypt which is kinda deprecated
So, is there a function or plugin i can use to help me to decrypt this JSON files ?
i’m using v5.11 beta, which has Oauth 2.0 which included in my project too
waiting for your help

Also i’m asking about arabic support in JSON reading, if the JSON has arabic text, the katalon can’t read it and show it as a hashed view
any help in this issue too ?
