Hi, my name is Anderson Souza, I hope I can help you with your issue.
File encryption helps protect your data by encrypting it. Only someone with the right encryption key (such as a password) can decrypt it.

The basic concept behind the use of encryption is that it can only be undone by someone who has the decryption key. Without it, it will not be possible to access the files.
