vbcs decrypt/encrypt javascript api

Summary:

I need to decrypt/encrypt data in my vbcs's site. I've read about a lot of js api's i can use

Please, can someone advice about a js api i can use? May be a browser's native funcionality that allows me to easily encrypt/decryt by providing a simple token by a final user

I you can supply an example, i would appreciate
