Fernet

Fernet is a specific type of encryption that ensures data remains secure and private. It uses a combination of symmetric key cryptography, meaning the same secret key both encrypts and decrypts information. Fernet guarantees the data hasn't been tampered with by including integrity checks, and it also ensures the data remains confidential. It's widely used in applications requiring secure data transfer or storage because it’s easy to implement and provides strong security guarantees, making sure sensitive information stays protected from unauthorized access or alteration.
