What is Advanced Encryption Standard?
[[File:VeraCrypt screenshot.png|thumb|VeraCrypt is a program that gives the option to use AES for encryption]] In [[cryptography]], the '''Advanced Encryption Standard''' ('''AES'''), is a [[Symmetric-key algorithm|symmetric-key]], [[block cipher]]<ref>{{Cite web|url=https://cryptobook.nakov.com/symmetric-key-ciphers/aes-cipher-concepts|title=The AES Cipher - Concepts|website=cryptobook.nakov.com|access-date=2019-10-08}}</ref> algorithm that was selected by the [[National Institute of Standards and Technology|National Institute of Standards and Technology (NIST)]] in 2001. It was selected for [[Encryption|encrypting]] data.
