Why Is Cryptography So Important?

Cryptography is a method of protecting information and communications through the use of codes so that only those for whom the information is intended can decrypt and it. The pre-fix “crypt” means “hidden” or “vault” and the suffix “graphy” stands for “writing.”

Modern cryptography concerns itself with the following four objectives:

Procedures and protocols that meet some or all of the above criteria are known as cryptosystems. Cryptosystems are often thought to refer only to mathematical procedures and computer programs; however, they also include the regulation of human behavior, such as choosing hard-to-guess passwords, logging off unused systems, and not discussing sensitive procedures with outsiders.

Authenticated Encryption with Additional Data

The XChaCha20-Poly1305-IETF construction can safely encrypt a practically unlimited number of messages with the same key, without any practical limit to the size of a message (up to ~ 2⁶⁴ bytes). As an alternative to counters, its large nonce size (192-bit) allows random nonces to be safely used.
