WebSep 20, 2024 · It's used in cryptography to flip bits of a message in a certain way such that the recipient can flip the same bits through knowledge of a secret key to recover the message, although anyone intercepting the message shouldn't be able to recover the original message without knowledge of this key. WebApr 12, 2024 · The Advanced Encryption Standard (AES) is a symmetric block cipher that's used for classified information by the U.S. government. Development of AES began in 1997 by NIST in response to the need for an alternative to the Data Encryption Standard (DES, discussed below) due to its vulnerability to brute-force attacks. http://aes.cryptohack.org/passwords_as_keys/ bungeecord random motd
