Como comprar Bitcoin em um banco?

Could you please elaborate on the process of purchasing Bitcoin from a bank? Are there specific banks that offer this service, or is it a general procedure that varies depending on the institution? What are the steps involved in the transaction, from initiating the purchase to receiving the Bitcoin in your digital wallet? Additionally, are there any fees associated with this method of acquisition, and if so, how are they calculated? Furthermore, are there any security measures in place to protect the customer's funds and personal information during the transaction?
