Encrypting sensitive data

I am storing some sensitive data like personal details of members and I want to make sure it’s rock solid and secure. My thinking is to create encryption keys to encrypt the data and create a decrypt key for each member of staff where their key is encrypted with their password. Is all this possible in Wappler? I want to make sure that even if someone gets all the code and all the data, they still can’t actually access anything important.

I also want to encrypt any uploaded documents/files in the same way.
