Data actions (encryption, decoding) !

Hello, I would like to suggest a feature to add encryption actions of text and files. It's so important so we can secure our data, to store it, or to send it. There's an application that you can use to know methods and algorithms (Crypto - Tools for Encryption & Cryptography)
and actions to encode and decode Json values, and also add different data types such as lists and more. The app is insane and with these actions we can communicate with other tools and programs easily and securely.
and thanks for reading this and I appreciate your time and effort. Thank you !

One method is to add a dot (.) before file names to hide them within your device. You can do this with the shell script action by using the mv command. mv /storage/emulated/0/text.txt /storage/emulated/0/.text.txt

Maybe you can use text manipulation to implement this: https://en.wikipedia.org/wiki/Caesar_cipher
Of course you will need to make one the opposite so that the recipient can read it as normal text.

Alternatively, you can use the shell script action to zip a file/folder and then change the .zip extension.
Read here about zipping but ignore the installation part as it will already be installed: https://linuxize.com/post/how-to-zip-files-and-directories-in-linux

Then you can alter the .zip extension with the mv command again.

you can unzip with:
unzip /storage/emulated/0/text.zip
