File encryption allows you to add another level of protection, thereby guaranteeing that the file will be read only by its creator. If this object is opened by any other user, even with administrator privileges, a blank screen or a meaningless character set will appear in front of him. In other words, the encrypted data cannot be read unless you are working in the system under your personal account. Consider the issues related to this in more detail.
