Intro: In 2000, The Rijndael algorithm is chosen as the Advanced Encryption Standard. This cipher algorithm was developed by two Belgian cryptographers, Joan Daemen and Vincent Rijmen. At its most basic level, encryption allows us to encode information so that only those who know the encrypting key can decrypt the data. Without the key, it looks like random letters and symbols. With the key, the jumble of seemingly random text turns back into its original message.
