Creating custom encryption & decryption function

[anomic30]

Currently, we are using a custom npm package for the encryption/decryption of the files. This package doesn't have proper asynchronous methods. So we would like to create our own custom functions which are asynchronous and error-free. These functions should be able to catch errors and show the appropriate message properly.

we can use crypto-js for encryption and decryption.
