Feat: encrypt one share using aes-256 and store it in db

I have added the functionality of encrypting one of the shares using the AES-256-CBC encrypting module and then storing it into the respective field of the user's database. Also, I fixed some function naming issues of the encrypting modules for AES, AWS, and GCP

This video demonstrates the encryption of the share as well as saving it in the database:
