Feat: added encryption of shares

I've added AES encryption to the shares generated during the secret splitting process. This ensures that even if someone gets their hands on the shares, they won't be able to access the original secret without the proper keys.

Hi @lakshayvaishnav why are we not using IV over here ?

would like to know if it was a deliberate decision and if not then we need to use IV while encrypting
