What is cryptography?

Cryptography is the study of encryption and decryption, how to make files and folders unreadable to unauthorized users, how to make the network connection more secure, so that it is unbreakable, and the strength of the randomness, so that it is harder for anyone to guess the key or the input. Cryptography is how we can achieve more secure and robust connections to elevate our privacy.

Advancements in cryptography makes it harder to break encryptions so that encrypted files and folders, or encrypted network connections are only accessible to authorized users.
