Introduction to cryptography

Cryptography is a branch of mathematics responsible for safeguarding information exchange between communicating parties and includes techniques for message integrity checking, sender/receiver identity authentication, and digital signatures. It directly supports the Confidentiality element of the CIA triad, a core model of information security.

Here are four common cryptography algorithms:
